In this Volume twenty-two groups of Rhynchophora, all belonging to the Subfamily Curculionine, the Sitonina to the Cryptorrhynchina inclusive, are dealt with. The classification adopted is mainly that of Lacordaire, modified to some extent to conform with the system followed by Leconte and Horn, who were the first to detect the real structural differences between the Otiorrhynchine and the Curculionine proper. The ‘ Munich Catalogue’ gives but little idea of the vast number of Rhynchophora, especially as regards the group Cryptorrhynchina, inhabiting Tropical America, and it will already be seen that they are probably more than twice as numerous in species as the Phytophaga in this region. Gemminger and Harold (1871-6) give, for the whole world, Rhynchophora [Curculionide, Anthribide, Brenthide, and Scolytide | 11,591 species, and for the Phytophaga [Chrysomelide, Hispide, and Cassidide] 10,196 species. In this Volume alone, one of four or five that will be required, no fewer than 1365 species are enumerated ; whereas the total number of Central-American Phytophaga (inclusive of Hispide and Cassidide) as given in this work (1892-4) is 2619. In Schénherr’s ‘Genera et Species Curculionidum,’ concluded in 1845, scarcely any species are recorded from Central America proper, 7. ¢. from between Mexico and the South-American mainland, and it is therefore not surprising that a very large proportion of the species enumerated are new. A few of those described, however, will no doubt prove to be synonymous with South-American forms when the types can be compared. The identification of closely allied obscure species from description alone, from specimens from such distant localities as Mexico and Brazil respectively, is obviously so uncertain that it is preferable to describe such forms as new, notwithstanding the risk of adding to the synonymy. The genera of the group Cryptorrhynchina still remain in inextricable confusion, and little more has been done vil INTRODUCTION. here than to follow Chevrolat, Pascoe, and Faust in placing a certain number of the more striking forms under separate generic names. The completion of such a task is beyond the scope of the present work, and it can only be attempted when the whole of the American Rhynchophorous fauna is studied. Amongst the various groups enumerated, it may be noted that only one of those at all numerous in species, the Anthonomina, is about equally well represented in the United States of North America. The Hyperina, Cleonina (Lizus excepted), Pissodina, Erirrhina, Tychiina, and Balaninina are mostly Holarctic, the species becoming fewer in number within the tropics, such well-known genera as Cleonus and Pissodes not extending south of Mexico. On the other hand, the groups Cryptorrhynchina, Hylobiina, Cholina, &c., the members of which mostly attack trees in their various stages of decay, are extremely numerous, both in species and individuals, throughout the warmer regions of America. The Sitonina have doubtless been introduced into Mexico from Europe. The food-plants and habits of scarcely any of the Central-American Curculionine have been observed, unfortunately, though it may be stated in a general way that a very large proportion of the specimens belonging to the groups Hylobiina, Anchonina, Otidocephalina, Erodiscina, Lamosaccina, Cholina, and Cryptorrhynchina obtained by the present writer were beaten from the withered leaves or branches of fallen deciduous trees in forest-clearings. One species, however, Anthonomus grandis, the ‘* Mexican Cotton-boll Weevil,” has now become notorious as a destructive insect wherever cotton is cultivated. We are indebted to the authorities of the Berlin Museum for the loan of their Mexican and Central-American Otidovephalina; to Dr. Chr. Aurivillius and Dr. Yngve Sjostedt, of the Stockholm Museum, for communicating a number of types described in Schonherr’s work, as well as some others contained in the Chevrolat collection ; . and to Dr. K. M. Heller, of the Dresden Museum, for the loan of many Cryptorrhynchids described by Faust. Prof. G. Biolley, of San José, Costa Rica, has from time to time forwarded various Costa Rican forms, thus helping us to give a better account of the fauna of that country than we have been able to do with the other families of beetles already treated. Mr. H. F. Wickham, of Iowa City, too, has again been kind enough to supply specimens of many North-American species, invaluable for comparison with Mexican insects. INTRODUCTION. Vii Of the thirty-five plates issued, all of which have been drawn and lithographed by Mr. FE. Wilson, of Cambridge, nineteen (Plates X. and XVIII.—XXXV. inclusive) are coloured and one (Plate XII.) partially coloured. The complete classified list of the species figured, as given in the other Volumes of Coleoptera already finished, has been omitted as unnecessary, the supplement to the present Volume being very short.

The numerous “Groups” of Curculionine will be dealt with as is most convenient, there being no other possible method of arranging the enormous amount of undescribed material amassed by us, unless publication is delayed till the whole of these insects have been thoroughly studied.—Ep.

Group HYPERINA. Hypérides, Lacordaire ; Phytonomini, Leconte & Horn (part.) ; Hyperini, Bedel, Petri. This group contains but few representatives in Tropical America, and these mostly belonging to the genera Isorrhinus and Phelypera. Listronotus, Jekel (a genus represented in Mexico, and extremely closely allied to Desiantha, Pase., of Australia), referred to the Hyperina by Leconte and Horn, seems to me to be more nearly related to the Erirrhina. HYPERA. Hypera, Germar, Mag. Ent. iv. p. 335 (part.) (1821); Capiomont, Ann. Soc. Ent. Fr. 1867, p. 490; Petri, Monogr. Hyperini, pp. 6, 25 (1901). - This genus, even if Phytonomus is retained as distinct, includes numerous represen tatives, most of which inhabit the Palearctic region. The single species now added from the mountains of Western Mexico is a very remarkable form *. * In the Sallé collection there is a specimen of Phytonomus rumicis (Linn.) labelled as from “ Mexico,” but further evidence is required before it can be admitted into our list. P. rumicis (?=diversus, Gyll., and comptus, Say) has, however, been recorded from North America. HYPERA.—ISORRHINUS. 3 1. Hypera ocellata, sp. n. (Tab. I. figg. 1, 2; 1a, profile of head; 14, meso- and metasternal side-pieces.) Oblong-ovate, black, shining ; thickly clothed above and beneath with small, narrow, grey scales, these becoming piliform on the head, rostrum, antenne, and legs, and on the terminal ventral segments, the upper surface also with scattered decumbent hairs; the elytra with eleven conspicuous black spots, each surrounded by a line of fulvous or ochreous scales—one on the humeral callus, one at the apex, and two on the dise of each elytron, and three on the suture (the anterior one of these being immediately behind the scutellum),—and a line of ochreous scales along the outer margin ; the head also with a line of similarly coloured scales extending round the eyes, except in front. Head densely, very finely punctate, foveate between the eyes; the latter transverse, somewhat coarsely facetted, and separated by a space about equalling their own length; rostrum stout, about as long as the prothorax, gradually widening outwards, densely punctate to near the tip, which is smooth ; joints 1 and 2 of the funiculus subequal in length, the scape reaching back to the anterior margin of the eye. Prothorax transverse, barely one-half the width of the elytra, narrowed and slightly constricted in front, the sides parallel from the middle to the base, the surface densely, very finely punctate. Elytra oblong-oval, truncate at the base, the humeri obliquely truncated and somewhat swollen, the disc flattened anteriorly ; finely punctate-striate, the interstices almost flat and minutely, rugulosely punctate. Beneath closely, very finely punctate. Ventral segments 1 and 2 very broadly and feebly depressed down the middle in the ¢. Length * 94, breadth 44 millim. (¢ 2.) Hab. Muxico, Omilteme in Guerrero 8000 feet (H. H. Smith). Two specimens. In its essential characters this insect agrees very well with [/ypera, but the general coloration is very peculiar, the elytra having eleven irregularly shaped black spots, each surrounded by a ring of ochreous or fulvous scales. The eyes are somewhat widely separated. ISORRHINUS. Isorhinus, Capiomont, Ann. Soc. Ent. Fr. 1867, p. 443 ; Petri, Monogr. Hyperini, p. 5 (1901). Isorrhinus, Gemminger & Harold, Cat. Col. viii. p. 2389. A genus including a few Mexican species f, and differing from Phelypera in the very short rostrum. J. gibbus and J. undatus have the eyes larger and more rounded than in either of the forms described by Capiomont, J. gidbus also having the prothorax widened behind, the elytra gibbous towards the base, and the legs elongate. It is unnecessary, however, to treat either of these insects as generically distinct from Lsorrhinus. 1. Isorrhinus fuscomaculatus. (Tab. I. figg. 2 ¢; 2a, profile of head.) 2. Lsorhinus fuscomaculatus, Capiom. Ann. Soc. Ent. Fr. 1867, p. 444°. 3. Iserhinus chevrolati, Capiom. loc. cit. p. 445°. Hab. Mexico (coll. Chevrolat?), Tuspan, Yucatan 4.—? Borrvia}. I. fuscomaculatus and I. chevrolati are, no doubt, sexes of the same species, one of * The length is given exclusive of the rostrum in all the species described in this volume. + The locality ‘ Bolivia” quoted for one of them is probably a mistake. BB 2 4 | RHYNCHOPHORA. each of them being now before me, and these are female and male respectively ; the male is labelled with the locality “Tuspan.” In this insect the eyes are coarsely facetted and very narrowly separated above. ‘The elytraare irregularly and subequally tessellated with fuscous and ochreous scales; and the prothorax has a line of ochreous scales down the middle. ‘The male has the first ventral segment sulcate, and the fifth slightly depressed down the middle, there being a patch of dark brown scales on either side of this space at the apex. One of the types of J. chevrolati, from Tuspan, is figured. 2. Isorrhinus depressus, sp. n. (Tab. I. figg. 8, ¢; 34, profile of head.) Oblong-ovate, depressed, piceous, the antenns and the tarsi in part ferruginous ; variegated above with rather coarse, piliform, fuscous and cinereous scales, and with scattered decumbent hairs, the prothorax with a median line of cinereous scales ; the squamosity of the under surface and legs in great part cinereous. Rostrum short and stout, closely punctate ; joints 1 and 2 of the funiculus equal in length; eyes large, somewhat coarsely facetted, almost contiguous above. Prothorax transverse, densely punctate, the sides parallel from the middle to the base. Elytra more than one-half wider than the prothorax, moderately long, flattened on the disc to about the middle, subparallel in their basal half, the humeri rounded; seriate- punctate, the interstices feebly convex, and closely, very minutely punctate. First ventral segment broadly and deeply, and the fifth shallowly, depressed down the middle, and the latter with a broad patch of blackish scales at the tip, in the ¢. Length 5-6, breadth 23-3 millim. (d 2.) Hab. Mexico, Cuernavaca in Morelos (/ége). Eleven specimens. Very like I. fuscomaculatus, but less convex, the elytra flattened on the disc anteriorly and with the sides straighter, the eyes larger and almost contiguous above. The dark scales predominate on the elytra. 3. Isorrhinus confusus. (Tab. I. figg. 4, 9; 44, profile of head.) Phytonomus confusus, Boh. in Schénh. Gen. Cure. vi. 2, p. 350°. Tsorhinus confusus, Capiom. Ann. Soc. Ent. Fr. 1867, p. 446’. Hab. Mexico (coll. Chevrolat'), Oaxaca (Hoge). The type of this species, kindly lent by Dr. Aurivillius, is a male, and a female obtained by Herr Hége at Oaxaca agrees very well with it, except in its much larger size. Both have the elytra asymmetrically tessellated with patches of fuscous scales, the rest of their squamosity being ochraceous. ‘There is a line of ashy scales down the middle of the prothorax. ‘The eyes are rather finely facetted, and separated above by a space about equalling the length of the first joint of the funiculus. The first ventral segment is depressed down the middle in the male. Compared with J. depressus the present species is much smaller and less elongate, the eyes are less approximate above - and more finely facetted, and the elytra are more irregularly tessellated with fuscous, the light colour predominating. ISORRHINUS. 5 4. Isorrhinus gibbus, sp. n. (Tab. I. figg. 5, 5a, ¢ ; 6, 2 ; 6a, last ventral segment, 2.) Ovate, robust, black, the antenne in part ferruginous; thickly clothed with narrow intermixed reddish-brown (or fuscous) and whitish scales, which have a cupreous or violaceous iridescence in certain lights, and also with scattered decumbent dark hairs, the squamosity of the scutellum black, and that of the under surface and legs in part whitish, that of the under surface sometimes almost entirely of this colour. Head closely punctate, faintly foveate between the eyes; the latter large, finely facetted, somewhat prominent, rounded as viewed from the side, separated above by a space about equalling one-half the width of the rostrum; rostrum very short and stout, closely punctate, deeply triangularly impressed at the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, subconical, the sides rounded and converging in front and straight behind; the surface densely, minutely punctate, with slightly larger punctures intermixed. Elytra oval, gibbous towards the base, about one-half wider than the prothorax, gradually narrowing from a little below the shoulders, which are rounded; rather finely seriate-punctate, the interstices almost flat and rugulosely punctate, the fifth very little raised posteriorly. Beneath closely punctate. First and fifth ventral segments broadly depressed along the middle in the ¢, the fifth foveate at the apex inthe 9. Legs elongate. Length 9-103, breadth 43-53 millim. (d Q.) Hab. Mexico, Acapulco, Iguala, Matamoros Izucar, Juquila (Hoge), Mescala in Guerrero (H. H. Smith). Sent in plenty from Acapulco. This species differs from the typical Jsorrhiné in the larger and more rounded eyes (though they are still broader than long), which are finely facetted and not all approximate above, the posteriorly widened prothorax, the gibbous elytra, the longer legs, &c. In the form of the eyes it nearly agrees with I. undatus, except that in the latter they are a little more transverse. 5. Isorrhinus undatus, sp.n. (Tab. I. fig. 7, 3; 74, profile of head.) Ovate, convex, black, the antennee in part and the tarsal claws ferruginous ; densely clothed with brown or brownish-grey piliform scales, and with scattered decumbent hairs, the elytra usually with a more or less distinct, common, angulate, grey or greyish-ochreous fascia a little beyond the middle ; the squamosity of the under surface and legs cinereous or brownish-cinereous. Rostrum short and stout, closely punctate, except at the tip, feebly carinate down the middle ; joints 1 and 2 of the funiculus subequal in length ; eyes large, rather prominent, finely facetted, narrowly separated above in the 2 and almost contiguous in the ¢. Prothorax transverse, the sides rounded and converging anteriorly and straight behind ; the surface densely, finely punctate, transversely depressed in front of the basal margin. Elytra more than one-half wider than the prothorax, subcordiform in the g, somewhat parallel-sided in the 9; seriate- punctate, the interstices flat and closely, rugulosely punctate. Beneath closely, finely punctate. First and second ventral segments broadly and shallowly depressed down the middle, and the fifth flattened and sparsely. squamose along the centre, in the ¢. Length 6-7}, breadth 34-4 millim. (¢ @.) Hab. Mexico, Ventanas, Acapulco, Juquila (Hdge). Sent in numbers from Ventanas, in Western Mexico. Differs from J. fuscomaculatus in its broader and more robust form, the larger, more prominent, and finely facetted eyes, the piliform squamosity of the upper surface, &c. The elytra usually have a common angulated pallid fascia (formed by an oblong patch at the middle of the suture and a transverse postmedian fascia on the disc of each elytron) beyond the 6 RHYNCHOPHORA. middle. The metathoracic episterna are broad, but they are a little more narrowed behind than in J. fuscomaculatus. PHELYPERA. Phelypera, Capiomont, Ann. Soc. Ent. Fr. 1867 ; Petri, Monogr. Hyperini, p. 5 (1901). Eight species were referred to this genus by Capiomont, one of these being a cma and widely distributed insect within our limits, the genus ranging from Mexico to Uruguay. I. Pronotum without transverse impression at the base. 1. Phelypera isthmica, sp. n. (Tab. I. figg. 8, ; 84, profile of head.) Broad-ovate, pitchy-black, the antenne and tarsi in part ferruginous ; thickly clothed with narrow tawny scales, the elytra mottled with whitish and blackish scales, the lighter-coloured ones showing a tendency to form spots on the alternate interstices. Head closely punctate ; the eyes large, coarsely facetted, and contiguous above; rostrum slightly longer than the prothorax, moderately stout, thickly punctured, obsoletely carinate down the middle ; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, as wide at the middle as at the base, the sides slightly sinuate behind and rounded and converging in front, the hind angles acute ; the surface densely, finely punctate, without trace of transverse depression before the base. Elytra comparatively short, broad, nearly twice the width of the prothorax, the humeri rounded ; rather coarsely seriate-punctate, the interstices convex, and minutely, rugulosely punctate, the fifth very little raised posteriorly. Beneath closely, finely punctate. First and second ventral segments slightly depressed along the middle. Legs comparatively short. Length 7, breadth 4 millim. (¢ .) Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). One specimen, slightly abraded. This insect has the head and rostrum formed as in P. distigma, but differs otherwise in the less dilated, unimpressed thorax, the shorter, dissimilarly coloured elytra, which are without sete and have the fifth interstice much less raised posteriorly, the shorter legs, &c. II. Pronotum transversely impressed at the base. 2. Phelypera distigma. (Tab. I. figg. 9,¢,var.; 94, profile of head; 10, 2 .) Phytonomus distigma, Boh. in Schénh. Gen.

PHELYPERA.—HILIPUS. 7 A very variable species as noted by Capiomont. Both light and dark forms (one of each of which is figured) have been found at Tapachula, Acapulco, and Chacoj. The males have the rostrum shorter than in the female, and the first ventral segment broadly depressed in the middle behind. Group HYLOBIINA. This group is nearly equivalent to the “ Hylobiides vrais” and the ‘ Molytides ” of Lacordaire, the “‘ Hylobiini” of Leconte and Horn, and the “Curculionini” of Bedel, except that Pissodes, Anchonus, and Oncorrhinus are excluded, the two latter belonging to the “ Anchonina,” which is distinguishable by the globose, smooth, deeply inserted head. The Hylobiina are chiefly recognizable by the long curved claw at the apex of each of the tibia, the apex itself being oblique, dilated, and concave, with the corbel closely ciliate on either edge; and the stout or moderately stout rostrum, with the anterior opening of the scrobes almost always visible from above. The gula, except in Telys, is transversely strigose. The strongly retractile legs and the powerful tibial claws enable these insects to cling very firmly to the foliage and bark of trees. In most of the genera the femora are acutely spined and the wings fully developed. Hilipus represents Hylobius* in Tropical America. Anchonomorpha and Rhecas form a connecting-link with.the “ Anchonina,” the first-mentioned having the first and second ventral segments connate at the middle, and the latter having the elytra soldered together. | HILIPUS. Heilipus, Germar, Ins. Spec. Nov. p. 399 (1824) ; Lacordaire, Gen. Col. vi. p. 457. Hilipus, Gemminger & Harold, Cat. Col. viii. p. 2425. Hilipus, as here restricted, still includes a vast number of species, and in this respect must far outnumber Otiorrhynchus, one of the most numerously represented genera of the Rhynchophora. It might be further subdivided, as noted by Lacordaire, by the exclusion of the forms having the inner apical angle of the tibie mucronate f (our Section II.) ; but as this would -remove: more than half the species from the genus, and as it is in some cases a peculiarity of the female only, I do not think it advisable to adopt this course. The insects here referred to Hilipus have the scrobes formed to receive the scape only of the antenna; the seventh joint of the funiculus not forming part of the club; the eyes large and more or less approximating above; the scutellum mode- rately large; the femora clavate and acutely dentate ; and the tibie armed with a long claw at the apex, this (in the species of Section I1.) being sometimes ditferently placed * In the Sallé collection there is a mutilated specimen of Hylobius pales, Herbst (=assimilis, Boh.), labelled as from “‘ Toxpam, Mexico,” but there must be some mistake about the locality. + To avoid confusion the term “‘ mucronate ” is here applied only to the smaller tooth at the inner apical angle of the tibie, the larger, apical, one being called the “ claw.” 8 RHYNCHOPHORA. in the two sexes. In Hilipus and the allied genera the tibie are furnished with two matted, long, spine-like tufts of hair near the inner apical angle, these projecting forwards on either side of the claw. The males are usually distinguishable by the shorter and more rugose rostrum, and often by a longitudinal depression on the first ventral segment, or two tufts of matted piliform scales at its apex, as well as by the different position of the tibial claw in some cases. Various modifications of structure are to be found in H. securiger (a peculiarly;formed antennal club in the ¢ ), H. appen- diculatus (the claw of the posterior tibia replaced by a spoon-shaped process in the ¢ ), H. strigipectus (a dense brush of long hairs on the first and second joints of the anterior tarsi in the 3), H. empiricus, H. penicillatus, &c. The genus is characteristic of the forest-regions of Tropical America, the various species attacking the branches of fallen trees, by beating which very many forms were obtained by myself in Guatemala and the State of Panama.

Mextco2, Playa Vicente, Toxpam (Sai/é), Jalapa, Cordova, and Paso de San Juan in Vera Cruz (Hoge), Ojo Chico and Jalapilla (fide Chevrolat 1). Apparently not uncommon in the State of Vera Cruz. Distinguishable from H. elegans and other allied forms by the broad, sinuous, white vittee not reaching the apex of the elytra, though sometimes extending along the suture to near the tip. The head is deeply foveate between the eyes, which are narrowly separated. The antenne are inserted before the middle of the rostrum, which is longer in the female than in the male; the first and second joints of the funiculus are subequal in length. The venter is broadly depressed down the middle in the males, The sculpture of the prothorax and elytra is variable. 2. Hilipus elegans. (Tab. I. figg. 12, ¢; 124, profile of head; 13, 3, var.) Heilipus elegans, Guér. Icon. Régne Anim., Ins. p. 148’. Hab. Guatemata, Cerro Zunil (Champion); Costa Rica (Pittier, in Mus. Brit.) ; Panama, Bugaba, Volcan de Chiriqui 2000 to 8000 feet, Caldera, David (Champion), Chiriqui (ex Boucard).—Co.omsiat. A very variable insect, but always separable from the Mexican H. cruciatus by the sinuous whitish or pale ochreous vitte extending to the apex of the elytra, and more or less surrounding the subapical callosities, which are bare at the summit, as is also the suture. In both species the elytral vittze are sometimes broadly interrupted beyond the middle, and often show a tendency to become broken up into spots; and in H. elegans they are sometimes again interrupted (as described by Guérin) before the apex, so as to leave an isolated apical spot. The fifteen specimens from Cerro Zunil (fig. 13) have the inner and outer margins of these stripes much less indented, and the subapical callosities indicated by a large bare spot. Amongst our long series from Chiriqui, one only (the insect obtained from Boucard) shows the broad depression on the disc of the prothorax before the base, mentioned by Guérin, and exhibited in the South- American individuals before me; others, again, from the same district, are much less elongate. The rostrum is curved and stout. The antenne are inserted before the middle in both sexes, but nearer the tip in the males than in the females. Length (excluding rostrum) varying from 9-17 millim. 3. Hilipus albopictus, sp. n. (Tab. I. fig. 14, ¢.) Very like H. cruciatus, Chevr., but differing as follows:—The white markings much reduced in extent—the humeral patch on the elytra represented by a narrow stripe extending forwards from the second one, and forming a continuation of the prothoracic vitta, which is also much narrowed before the middle, the BIOL. CENTR.-AMER., Coleopt., Vol. IV. Pt. 4, May 1902. CC 10 | RHYNCHOPHORA. anteapical patch represented by an angulated transverse fascia ; the rostrum carinate at the base; the prothorax less rounded at the sides, and therefore somewhat conical in shape, irregularly granulate (due to the punctures being confluent and the interstices raised), without trace of raised median line; the elytra closely seriato-granulatc, the punctures of the striw scarcely discernible; the upper surface duller and thickly clothed with narrow, minute, greyish scales, Length 16, breadth 63 millim. (d.-) Hab. Muxtco, Cuernavaca in Morelos (H. H. Smith). One specimen. This may be an extremely aberrant form of H. cruciatus ; but as we have nothing intermediate, and the insect inhabits a different district in Mexico, it is worthy of a name. In Dr. Sharp’s collection there is a single (2?) example of a very closely allied species, from Colombia, labelled H. mirus, Chevr. (=viator, Jekel), n. sp. 4. Hilipus fenestratus, sp.n. (Tab. I. fig. 19, ¢ .) Oblong-oval, moderately shining, black or piceous, the prothorax with a white vitta on each side, narrowing in front; the elytra each with three large, white, oblong, suboval patches—one at the base, oblique, directed outward, another, below it, directed inward and downward (these two often connected laterally and forming a large curved or S-shaped patch), and a third, transverse, sometimes connected with the opposite one at the suture,—each enclosing numerous bare longitudinal spaces, and sometimes with an additional white spot before the apex; the legs, rostrum, and under surface with scattered, narrow, white scales. Head deeply foveate between the eyes, which are narrowly separated ; rostrum comparatively slender, curved, about one-third longer than the prothorax, coarsely punctured at the sides towards the base, for the rest almost smooth ; antenne inserted long before the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, rounded at the sides before the middle, and much narrowed in front; the surface coarsely, irregularly punctate, and often with minute interstitial punctures and indications of a smooth median line anteriorly. Elytra moderately elongate, one-half wider than the prothorax, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices flat and in some specimens transversely wrinkled. First ventral segment broadly depressed down the middle in the male. Length 12-154, breadth 43-63 millim. (¢ 9.) Hab. Guatremaa, San Juan and Purula in Vera Paz (Champion). Found in plenty in the forest-regions of Alta Vera Paz. This species is closely allied to H. cruciatus, but has a longer rostrum, with the antenne inserted further from the tip, the prothoracic vitte narrow, and the elytral markings very differently arranged, each of the three large patches enclosing numerous, bare, parallel, longitudinal spaces. A specimen in the British Museum, labelled “ Mexico,” may belong here; but it has the white elytral patches much reduced in size, and without the distinct black lines. : 5. Hilipus albovenosus, sp.n. (‘I'ab. I. fig. 16, 2.) Oblong-ovate, shining, black, the prothorax with a white vitta on each side; the elytra with a double series of zigzag white lines, which here and there coalesce, so as to enclose three subtriangular spaces on the disc of each elytron, these spaces in one specimen including a small white spot; eke win ee rostrum, and legs with a few scattered, narrow, white scales, the propleura with a line of white scales Evi front of the anterior coxe, and the ventral segments exch with a few white scales along their anterior HILIPUS. 11 margin towards the sides, Head deeply foveate between the eyes, which are narrowly separated ; rostrum stout, curved, about as long as the prothorax, thickly punctured towards the base, smooth at the tip; antenng inserted a little before the apex of the rostrum, joint 1 of the funiculus slightly longer than 2. - Prothorax about as long as broad, much narrowed in front, and slightly sinuate at the sides behind, sparsely punctate, and with indications of a smooth, raised, median line towards the apex. Elytra one- half wider than the prothorax, subparallel towards the base, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices smooth and flat. Ventral segments 1 and 2 broadly depressed down the middle in the male. Length 123-16, breadth 5-6} millim. (¢ 9.) Hab. Mexico, Orizaba (Sal/lé). Two specimens, the female much smaller than the male, and also differing from it in having the white lines on the elytra a little wider and extending down the suture towards the apex. JH. albovenosus is a close ally of the Mexican H. cruciatus; it may be nothing more than an extreme form of H. fenestratus, but I have seen nothing intermediate. 6. Hilipus hieroglyphicus, sp. n. (Tab. I. fig. 17, ¢ .) Elongate-oval, moderately shining, black, the antennal scape in part and the tips of the tarsi reddish ; the prothorax with a narrow submarginal vitta, which is continued down the elytra to near the middle, and has three short branches extending inward and one outward, some very small spots on the elytra inside this, an oblique fascia at about one-third from the apex, and four more or less coalescent streaks beyond it, white; the legs, rostrum, and under surface with scattered, narrow, white scales. Head deeply foveate between the eyes, which are somewhat distant; rostrum stout, curved, not longer than the prothorax, closely, coarsely punctate, much smoother at the tip; antenne inserted a little before the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed in front, and sinuate at the sides behind; the surface very sparsely, coarsely, shallowly punctate, with traces of a smooth, raised, median line in front. Elytra elongate, much wider than the prothorax, almost parallel to about the middle, conjointly rounded at the apex, the humeri rounded, seriate-punctate, depressed behind the scutellum, the interstices flat. First ventral segment broadly and shallowly depressed down the middle. : Length 144, breadth 53 millim. (? 2.) Hab. Guatemaua, Purula in Vera Paz (Champion). One specimen. The arrangement of the elytral markings, the elongate anterior streak of which is somewhat E-shaped, distinguishes this insect from H. sticticopterus and other species with white submarginal prothoracic vitte and comparatively smooth upper surface. 7. Hilipus limbatus, sp. n. (Lab. I. figg. 18, ¢; 184, profile of head.) Oblong-ovate, rather broad, shining, piceous; the prothorax with a broad vitta on each side and the elytra with a still broader, strongly sinuous one on the outer part of the disc (formed by a coalescent curved stripe and a large apical patch), the latter nearly reaching the suture towards the apex and enclosing a rounded bare space on the subapical callosities, brownish-ochreous, edged on either side with white; the rest of the upper surface clothed with minute ochreous scales ; the under surface and legs with scattered, narrow, whitish scales, the propleura with a line of larger whitish scales before the anterior cox. Head foveate between the eyes, which are narrowly separated ; rostrum moderately stout, feebly curved, nearly twice as long as the prothorax, punctured laterally on the basal half, for the rest almost smooth; antennz CC 2 12 RHYNCHOPHORA. inserted at about the middle of the rostrum, joint 1 of the funiculus nearly one-half longer than 2. Prothorax broader than long, rounded at the sides, narrowed in front, depressed on the disc at the base ; coarsely, confluently punctate, with a smooth, raised, median line. Elytra one-half wider than the prothorax, subparallel in their basal half, depressed behind the scutellum, conjointly rounded at the apex, the humeri rounded; deeply seriate-punctate, the interstices flat and transversely wrinkled. First ventral segment depressed in the middle. Length 10, breadth 43 millim. (¢.) Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). One specimen. Very like some of the smaller and less elongate forms of the variable H. elegans; but with a longer, more slender, and less curved rostrum, the antenne inserted at about the middle of the latter and with a more elongate basal joint to the funiculus, the prothorax more transverse, &c. The markings of the upper surface are brownish, bordered on their edge with white, and very like those of some of the Guatemalan specimens of H. elegans. 8. Hilipus rectirostris, sp. n. (Tab. I. figg. 19, 2; 19a, profile of head.) Oblong-ovate, comparatively broad and short, shining, piceous, the femora in part and the rostrum more or less rufescent ; the prothorax with a broad whitish vitta on each side; the elytra with a very broad curved stripe on the outer part of the disc, extending from the base to about the middle, and a large apical patch, the two connected in one specimen, and the latter reaching the suture before the apex and enclosing a small bare spot on the subapical callosities, whitish or pale ochreous; the rest of the surface and the legs clothed with narrow ochreous scales. Head deeply foveate between the eyes, which are narrowly separated ; rostrum a little longer than the prothorax, stout, almost straight, thickly punctured, except towards the tip, obsoletely carinate at the base; antenne inserted far before the middle of the rostrum, joint 1 of the funiculus longer than 2. Prothorax broader than long, the sides much rounded and converging anteriorly; coarsely, confluently punctate, and with a smooth median carina. Elytra about one-half wider than the prothorax, comparatively short, subparallel towards the base, depressed behind the scutellum, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate, the interstices transversely wrinkled and towards the base granulate. Length 7-8, breadth 34-43 millim. (9.) Hab. Mexico (Sallé); Guatemana, Cerro Zunil (Champion). Two specimens, the Guatemalan one figured differing from the other in having the elytral markings longitudinally confluent. Differs from H. elegans and H. limbatus in the almost straight rostrum, which is also much shorter and stouter than in the jast-mentioned insect, and the relatively shorter elytra. There are two nearly allied South-American forms in the British Museum, labelled H. draco (Fabr.) and H. parvulus, Boh., respectively. 9. Hilipus ornatus, sp. n. (Tab. I. fig. 20, ¢.) Narrow, subcylindrical, shining ; rufo-piceous, the prothorax with a moderately broad whitish vitta on each side, narrowing in front; the elytra with a broad, irregular, sinuous stripe at the sides extending from the base to about the middle, from which a short ramus runs inward posteriorly to the third row of punctures, and a large transverse oval patch before the apex, nearly reaching the suture and enclosing a bare smooth space at the tip of the anteapical callus, also whitish, the edges of both markings more or less excised ; the upper surface elsewhere clothed with a fine ochreous pubescence; the under surface and legs with - HILIPUS. 13 narrow whitish scales. Head deeply foveate and punctured between the eyes, which are somewhat distant ; rostrum stout, curved, longer than the prothorax, somewhat coarsely punctured, except towards the tip, obsoletely carinate at the base, and with a short sulcus between the points of insertion of the antenne ; the latter inserted at about one-third from the apex of the rostrum, and with joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, somewhat rounded at the sides, irregularly punctate, the punctures becoming coarser and transversely confluent towards the base, the disc with a smooth central line, the flanks obsoletely granulate. Elytra elongate, subparallel in their basal half, conjointly rounded at the apex, a little more than one-fourth wider than the prothorax, flattened towards the suture, the humeri obliquely rounded, obtuse in front; seriate-punctate, the interstices transversely wrinkled. First ventral segment somewhat deeply depressed down the middle. Length 11, breadth 33 millim. ( 92.) Hab. Panama, Volcan de Chiriqui (Champion). One specimen. This species is coloured almost exactly like some of the small varieties of H. elegans occurring in the same district; but may be readily distinguish- able therefrom by its narrow subcylindrical shape, and the relatively much narrower elytra. The whitish markings are slightly tinged with ochreous, and those on the elytra more or less excised at the edges. 10. Hilipus furcatus, sp.n. (Tab. I. fig. 21, ¢.) Narrow, subcylindrical, shining, black; the prothorax with a rather broad whitish vitta on each side, which is continued down the outer part of the elytra to far beyond the middle, and there connected with a curved oblique fascia extending from near the outer margin to the suture before the apex, and has two rami extending inwards to the second or third row of punctures and another running outwards to near the margin ; the legs, rostrum, and under surface with scattered, narrow, white scales. Head coarsely punctured and foveate between the eyes, which are somewhat distant; rostrum stout, curved, about as long as the prothorax, coarsely punctured at the sides towards the base, for the rest almost smooth ; antenns inserted some distance before the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax convex, about as long as broad, rounded at the sides, narrowed in front, almost parallel behind ; the surface with widely scattered punctures, Elytra elongate, widest a little beyond the middle and here barely one-third wider than the prothorax, conjointly rounded at the apex, the humeri rounded; rather coarsely seriate-punctate, the interstices transversely wrinkled. Length 104, breadth 3} millim. (2.) Hab. Muxico, Jalapa (Hoge). One specimen. This insect somewhat resembles H. hieroglyphicus in general colora- tion; but is of more cylindrical shape, with the thorax more rounded at the sides and the elytra relatively narrower. 11. Hilipus cylindricus, sp. n. (Tab. I. fig. 22, 9.) Narrow, elongate, cylindrical, shining, rufo-piceous, blackish below the shoulders and at the apex of the elytra, clothed above with very minute, piliform, ochreous scales, which tend to become more concentrated towards the sides of the prothorax ; the prothorax with a small whitish spot on either side at the base ; the elytra with numerous more or less coalescent spots at and below the humeri, forming an irregular, oblong, humeral patch and an oblique one behind it, and others before the apex, the latter forming a common transverse fascia, ochreous; the under surface and legs with scattered, narrow, whitish scales, Head foveate and thickly punctured between the eyes, which are somewhat distant; rostrum stout, curved, longer than the prothorax, thickly punctured towards the base and smooth at the tip, and with a 14 RHYNCHOPHORA. short sulcus between the points of insertion of the antenne ; the latter inserted at about one-third from the apex of the rostrum, and with joints 1 and 2 of the funiculus equal in length. Prothorax rather longer than broad, the sides slightly rounded and converging a little towards the apex; the surface somewhat coarsely, confluently punctate, with a smooth, raised, median line in front, the interspaces here and there asperate. Elytra elongate, subparallel to beyond the middle, conjointly rounded at the apex, rather more than one-third wider than the prothorax, the humeri obliquely rounded, obtuse in front; seriate-punctate, the interstices transversely wrinkled. First and second ventral segments feebly depressed in the middle behind. . Length 10, breadth 3 millim. ( 9.) Hab. Nicaracva, Chontales (Belt). One specimen. Not unlike H. ornatus, but still narrower and more cylindrical, the prothorax without marginal vitte, the elytral markings reduced in extent and formed by coalescent spots. 12. Hilipus collectus. (Tab. I. figg. 23, 3; 234, profile of head.) Hilipus collectus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 68°. Hab. Nicaracua, Chontales 1 (Belt, Janson). We have received five specimens of this species. It is chiefly recognizable by the disposition of the pale ochreous markings on the upper surface, these consisting of a small spot or oblong streak on either side of the base of the prothorax and numerous spots on the elytra, the latter more or less concentrated in places, and showing a tendency to form a patch at the shoulders, an oblique fascia below this, and a transverse, common, anteapical band. The second joint of the funiculus is a little shorter than the first. 13. Hilipus trifasciatus, sp.n. (Tab. I. figg. 24, ¢; 25, 3, var. f.) Oblong-ovate, moderately shining, black, the head, the prothorax (except at the base and apex), the incras- sate portion of the femora, the apical joint of the tarsi, and the metasternum, in part, often rufous; the upper surface in fresh specimens thickly clothed with a very short fulvous or greyish pubescence ; the prothorax sometimes with an interrupted ochreous vitta on each side, usually reduced to a single spot at the base, and a similarly coloured streak beneath in front of the anterior coxe; the elytra with numerous patches of ochreous or whitish scales, these concentrated in places and forming three interrupted transverse fascie ; the underside and legs clothed with scattered, narrow, white scales. Head deeply foveate between the narrowly separated eyes; rostrum stout, curved, as long as or a little longer than the prothorax, irregularly and rugosely punctured at the sides, and sometimes carinate in the middle towards the base, for the rest almost smooth; antenne inserted far before the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, moderately convex, rounded at the sides, much narrowed in front and slightly so towards the base; the surface rather coarsely, irregularly punctate, usually with indications of a smooth central line, the interspaces sometimes more or less granulate. Scutellum sometimes with a few white scales. Elytra about one-half wider than and fully three times as long as the prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices flat, in some specimens faintly transversely wrinkled or obsoletely granulate. Venter smooth, in the ¢ broadly depressed down the middle of the first two segments. Var. a. Duller, the spots on the elytra less numerous; the prothorax sparsely punctured or with a few widely scattered granules. HILIPUS. 15 Var. /3. Prothorax very sparsely finely punctate, and with a short ochreous vitta on each side at the base ; the ochreous markings on the elytra in the form of short longitudinal streaks. (Fig. 25.) Length 10-18, breadth 41-7} millim. (¢ @.) Hab. Nicaraaua, Chontales (Belt, Janson, Richardson). Sent in plenty from Chontales, the form « indiscriminately with the type, by all three collectors, a few examples only showing a tendency to granulation on the prothorax and elytra. The elytral markings resemble those of H. collectus, from which the insect differs in its comparatively broader form, smoother rostrum, more distinctly punctured prothorax, &c. The var. f (fig. 25) is represented by a single specimen. 14. Hilipus belti, sp. n. (Tab. I. fig. 26, 2.) Oblong-ovate, shining, black, the prothorax (except at the base and apex), the incrassate portion of the femora and the side-pieces of the metasternum rufous; the prothorax with a small patch of white scales on each side in front; the elytra with numerous, irregular, transverse or oblique patches of white scales, tending to form fascize; the underside and legs with scattered, narrow, white scales. Head deeply foveate between the eyes, which are somewhat widely separated; rostrum very stout, curved, sparsely punctured towards the base, smoother at the tip, the antennal grooves rapidly descending; antenne as in 4. trifasciatus. Prothorax conical, distinctly longer than broad, sparsely punctate. Elytra more than three times the length and (at the widest part) nearly twice the width of the prothorax, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices faintly transversely wrinkled. Length 20, breadth 74 millim. (2.) Hab. Nicaragua, Chontales (Belt). ‘The above description is taken from a single female specimen, which is separable at a glance from the same sex of H. trifasciatus by the longer, conical prothorax, the more widely separated eyes, and the stouter and smoother rostrum. A male from Chontales (Janson) may belong here, as it has a similar head and rostrum; but the general shape of the prothorax is very like that of H. trifasciatus, except that there is a broad deep depression on each side of the disc before the middle. The prothorax, however, appears to be abnormally formed in this insect, which cannot, therefore, be certainly located till further material has been obtained. No such sexual difference in the form of the prothorax is known to me amongst any of the other species of the genus. 15. Hilipus albonotatus, sp. n. (Tab. II. fig. 1, ¢.) Elongate-oval, moderately shining, piceous or rufo-piceous ; the prothorax with a broad vitta on each side, narrowing in front, and the elytra with a small spot on the fifth interstice at the base, a short, oblique, angulated fascia towards the sides before the middle, and another before the apex, the latter nearly reaching the suture, white; the legs, rostrum, and under surface with scattered, narrow, whitish scales. Head deeply foveate between the eyes, which are narrowly separated ; rostrum distinctly longer than the prothorax, stout, curved, coarsely, sparsely punctate, except towards the tip, which is much smoother, the antennal grooves narrowly separated behind; antenne inserted a little before the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax slightly longer than broad, narrowing -4n front; the surface sparsely punctate, with a narrow, ill-defined, smooth space down the middle. Elytra elongate, one-half wider than the prothorax, widest at the base, conjointly rounded at the apex, 16 RHYNCHOPHORA. the sides almost straight to beyond the middle, the humeri rounded; flattened on the disc, depressed behind the scutellum, rather finely seriate-punctate, the interstices flat. Venter depressed along the middle towards the base. Length 133-15, breadth 43-5 millim. (¢ Q.) Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). Six specimens, apparently including both sexes, some of them having a longer ventral depression than others. Distinguishable from all the other Central-American forms by the disposition of the white markings on the elytra, these showing no tendency to vary. The antennal grooves are only separated by a very narrow ridge at the base of the rostrum beneath. 16. Hilipus albomaculatus, sp. n. (Tab. II. fig. 2, 2.) Oblong-oval, moderately shining, piceous ; the prothorax with a broad vitta on each side, narrowing in front, this being continued on the elytra to near the middle in the form of a broad, curved, submarginal band, and the elytra also with a broad auteapical fascia, not quite reaching the suture, white; the under surface and legs with scattered, narrow, white scales. Head deeply foveate between the narrowly separated eyes ; rostrum distinctly longer than the prothorax, curved, stout, coarsely, closely punctate and obsoletely carinate towards the base, much smoother at the tip, the antennal grooves narrowly separated behind 5 joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed in front and slightly so behind, sparsely punctate, with a narrow smooth space down the middle towards the apex. Elytra moderately elongate, widest a little below the base, conjointly rounded at the apex, the humeri broadly rounded and not at all prominent ; rather finely seriate-punctate, the interstices flat, the scutellar region depressed. Length 14, breadth 34 millim. (9.) Hab. Guatemata, Senahu in Vera Paz (Champion). One specimen. Very like H. albonotatus, but more robust, with shorter and stouter legs, the elytra broader and widest a little below the base, the prothoracic vitte continued on to the basal portion of the wing-cases in the form of a broad, curved, sub- marginal stripe, which extends inwards to the third row of punctures, and (like the subapical fascia) is not excised on either edge. 17. Hilipus stictopterus, sp. n. (Tab. II. figg. 3, ¢ ; 4, 3, var.) Elongate-oval, dull or slightly shining, black or piceous, the head and rostrum usually rufescent; the pro- thorax with a broad vitta on each side above and a narrow line in front of the anterior coxe whitish or pale ochreous; the elytra with numerous, more or less coalescent, similarly-coloured spots towards the sides, extending from the base to the apex; the under surface, legs, and rostrum with scattered, narrow, whitish scales. Head very deeply foveate between the eyes, which are narrowly separated ; rostrum about as long as the prothorax, stout, curved, thickly and rather coarsely punctured, except at the tip, which is much smoother ; antenne inserted a little before the apex of the rostrum, joint 1 of the funiculus slightly longer than 2. Prothorax as long as broad, narrowing from the middle forwards ; the surface closely punctate in some examples, almost smooth in others, and with indications of a smooth, raised, central line anteriorly. Elytra elongate, one-half wider than the prothorax, very gradually narrowing from the base, conjointly rounded at the apex, the humeri rounded; flattened on the disc, depressed behind the scutellum, seriate-punctate, the interstices broad and faintly transversely wrinkled. Ventral segments 1 and 2 with a few scattered punctures, and in the ¢ broadly depressed along the middle. HILIPUS. 1? Var. The elytral spots coalescent and forming a sinuous submarginal vitta (fig. 4). Length 123-16, breadth 34-53 millim. (¢ 9.) Hab. Panama, Volcan de Chiriqui (Champion). Found in plenty by myself on the slopes of the Volcan de Chiriqui, the form with a few shallow widely-scattered punctures only on the disc of the prothorax predominating. The variety, of which a single specimen only was captured, is very like the Costa- Rican Z. bivittatus, but has the prothorax more narrowed in front and the coalescent spots on the sides of the elytra forming sinuous vitte. The present species is nearly allied to H. collectus, from which it may be known by the complete prothoracic vitte, and by the elytral spots being concentrated along the outer part of the disc, showing no tendency to form oblique fasciz. The specimens with a closely punctured prothorax are more shining than the others. 18. Hilipus bivittatus, sp.n. (Tab. II. fig. 5, 2.) Elongate, subcylindrical, moderately shining ; the prothorax and elytra each with a broad submarginal pale ochreous vitta, the two vitte not confluent at the apex, the elytra in one specimen (2?) also with two detached similarly-coloured spots on the third interstice; the under surface with scattered ochreous scales, which are concentrated into small patches towards the sides; the legs and rostrum with narrow whitish scales. Head deeply foveate between the eyes, which are rather narrowly separated ; rostrum stout, curved, as long as the prothorax, rugosely punctured towards the base, almost smooth at the tip; antennee inserted far before the middle of the rostrum, joint 1 of the funiculus slightly longer than 2. Prothorax longer than broad, very little narrowed in front, the sides more parallel in the ?; the surface coarsely punctured (except upon the space occupied by the vittee), and with indications of a raised central line, the flanks rugosely punctured and in one specimen (2) granulate. Elytra elongate, subparallel to beyond the middle, at least one-half wider than the prothorax, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices broad and more or less wrinkled transversely. Ventral segments 1 and 2 with a few scattered punctures, and in the ¢ broadly depressed down-the middle. Length, g 13, 2 19; breadth, ¢ 4, Q 6 millim. Hab. Costa Rica (Van Patten), Caché (Rogers). One pair. The female has the prothorax longer and less narrowed anteriorly than in the male, and also much more coarsely and closely punctured. This species is allied to H. peplus, Guér., and other South-American forms, from which it may be distinguished by its narrower and more parallel shape, the straighter elytral vitte, &c. From H. norrisii, Guér.

Hilipus areolatus, sp. n. (Tab. II. fig. 6, ¢.) Elongate-ovate, shining, black or pitchy-black, the rostrum and tarsi sometimes reddish ; the prothorax with two lines of ochreous scales on each side, these becoming coalescent at the base and apex and enclosing an elongate-triangular space ; the elytra with two zigzag lines of similarly-coloured scales on the disc and another down the sutural stria, which are here and there connected so as to enclose large triangular spaces, the lines themselves becoming more tortuous at the apex; the rest of the upper surface, as well BIOL.

Head almost impunctate, deeply foveate between the eyes, which are narrowly separated ; rostrum curved, considerably longer than the prothorax, moderately stout, with a few scattered punctures only at the sides towards the base ; antenne inserted far before the middle of the rostrum, joint 1 of the funiculus longer than 2. Prothorax about as long as broad, rounded at the sides anteriorly, coarsely, confluently punctate, and sometimes with a narrow smooth space or raised line down the middle. Elytra rather convex, about one-half wider than the prothorax, sub- parallel at the base, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices smooth and flat.

Six examples. Easily distinguishable from all the other Central-American species of the genus by the network of narrow lines of ochreous scales on the upper surface, those on the prothorax enclosing a triangular space on each side, and those on the elytra here and there connected on the disc, enclosing large triangular spaces, except towards the apex, where the lines become tortuous. The South-American H. mysticus, Pasc., is an allied form, but differs from the present species in having the upper surface smoother, the femora partly red, and the sinuous lines on the elytra differently arranged, not forming a zigzag line on the disc of each. 20. Hilipus clathratus, sp.n. (Tab. IIL. figg. 7, ¢; 74, profile of head.) Oblong-ovate, shining, pitchy-black, the rostrum and the legs and antenne in part rufescent; the prothorax with a rather narrow ochreous vitta on each side, which curves inwards at the apex; the elytra with various sharply-defined ochreous lines—two of these enclosing a very large, common, rhomboidal space on the dise before the middle, the anterior line sending off a branch in front to meet the prothoracic vitta, the posterior line followed by two transverse ones (one oblique and the other curved),—and the outer and apical margins, a curved streak behind the subapical callus, and the punctures of the striew also, more or less clothed with similarly-coloured scales ; the rest of the upper surface with widely-scattered, narrow, ochreous, and the under surface and legs with whitish, scales, the pleura and each of the ventral segments 1-4 at the sides in front with lines of larger ochreous scales. Head deeply foveate between the eyes, which are rather narrowly separated; rostrum very nearly twice as long as the prothorax, rather slender, feebly curved, smooth, with a few scattered punctures only at the sides towards the base ; antenne inserted at about the middle of the rostrum, joint 1 of the funiculus nearly twice as long as 2. Prothorax broader than long, rounded at the sides and much narrowed in front, very coarsely confluently punctate, and with a smooth, raised, median line anteriorly. Hlytra one-half wider than the prothorax, parallel at the base and narrowing thence to the tip, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate, the interstices smooth and flat.

The type is stated to have passed its metamorphosis in a fruit of Persea (Laurus) drymifolia. H., lauri is easily recognizable by its very long rostrum, conical prothorax, and some- what cordiform elytra, the latter with two short, narrow, transverse, pale ochreous fascie. 22. Hilipus longirostris, sp.n. (Tab. IT. figg. 9, 2; 94, profile of head.) Oblong-ovate, shining, piceous, the rostrum, antenna, and legs reddish; the prothorax with an ill-defined oblique vitta on each side of the disc, which becomes very narrow in front and is formed of intermixed white and fulvous scales, the disc with scattered ochreous pubescence; the elytra with various oblong or rounded fulvous spots, which form an irregular curved series on the outer part of the disc below the base, a common, sinuous, transverse, subapical fascia, and a rounded apical patch, these markings interspersed with very small pure white spots, the rest of the surface with minute, scattered, ochreous scales; the under surface, legs, and rostrum with scattered, narrow, white scales. Head deeply foveate between the eyes, which are narrowly separated; rostrum slender, about three times as long as the prothorax, strongly curved, thickly punctured towards the base; antenne inserted slightly before the middle of the rostrum, joint 1 of the funiculus one-half longer than 2. Prothorax a little broader than long, deeply bisinuate at the base, narrowed in front, the sides rounded anteriorly and almost straight behind ; coarsely confluently punctate, and with a narrow smooth space down the middle. LElytra about one-half wider than the prothorax, narrowing from a little below the base, flattened on the disc, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate, the discoidal interstices strongly transversely rugose, the punctures of the striz thus appearing to be transversely confluent. Metasternum and venter almost smooth. Length 12, breadth 42 millim. (2.) Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). One example. This species is extremely like H. mixtus and H. atomarius, both of which inhabit the same district, but it is readily separable therefrom by the exceedingly long, curved, and slender rostrum. 23. Hilipus atomarius, sp.n. (Tab. II. figg. 10, 2; 10a, profile of head.) Oblong-ovate, shining, piceous or rufo-piceous, the rostrum rufescent at the apex in one specimen; the prothorax with a narrow white vitta on each side, upon which a few ochreous scales are visible, and scattered whitish pubescence ; the elytra with various oblong or rounded fulvous spots, which form a curved longitudinal series on the outer part of. the disc below the base, a common, sinuous, transverse, subapical fascia, and a small apical patch, these markings interspersed with very small white spots, which become larger at the base, the rest of the surface with scattered ochreous or white scales; the under surface, legs, and rostrum with scattered, narrow, white scales. Head very deeply foveate between’ the eyes, which are narrowly separated; rostrum stout, moderately curved, nearly twice as long as the prothorax in the 9, shorter in the ¢, rugosely punctured in its basal half; antenne inserted at about one-third from the apex of the rostrum in the ¢, further back in the 2, joint 1 of the funiculus slightly longer than 2. Prothorax a little longer than broad, narrowed in front, rounded at the sides anteriorly; coarsely, confluently punctate, and with a smooth, raised, median line. Elytra one-half wider than the prothorax, widest a little below the base and narrowing thence to the apex, flattened on the DD 2 20 RHYNCHOPHORA. disc, the apices conjointly rounded, the humeri rounded ; coarsely seriate-punctate, the discoidal interstices transversely rugose, the punctures of the striw thus appearing to be transversely contluent, Ventral segment 1 broadly depressed along the middle in the male, and narrowly 80 in the female. Length 11-14, breadth 43-5? millim. (d 2.) Hab. Paxama, Bugaba, Volcan de Chiriqui (Champion). One pair. Very like H. longirostris, but with a much stouter and shorter rostrum, even in the female; the prothoracic vitte more distinctly defined; the markings of the elytra very similar, except that there are larger patches of white scales at the base in the present insect. 24. Hilipus mixtus, sp. n. (Tab. Il. figg. 11, ¢; 11, profile of head.) Oblong-ovate, shining, piceous, the tarsi and the tip of the rostrum rufescent; the prothorax with an ill-defined oblique vitta on each side formed of intermixed white and fulvous scales, the disc with scattered ochreous pubescence; the elytra with various oblong or rounded fulvous spots, which tend to form an oblique fascia below the shoulders, a short transverse fascia before the middle (the two together forming an irregular curved band), a complete subapical arcuate fascia, and an apical patch, the rest of the surface with very small, scattered, whitish spots and narrow, minute, ochreous scales; the under surface, rostrum, and legs with scattered, narrow, white scales. Head very deeply foveate between the eyes, which are narrowly separated ; rostrum stout, curved, about one-third longer than the prothorax, thickly punctured towards the base, almost smooth at the tip; antenne inserted towards the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax a little longer than broad, much narrowed in front, rounded at the sides before the middle; coarsely confluently punctate, and with indications of a smooth, raised, median line. Elytra convex, one-half wider than the prothorax, widest about the middle, and slightly narrowing thence to the base, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices transversely rugose. Ventral segments 1 and 2 very broadly depressed down the middle. Length 14, breadth 54 millim. (¢-) Hab. Panama, Volcan de Chiriqui 5000 feet (Champion). One specimen. Very like H. atomarius and H. longirostris, but with a shorter rostrum, a longer prothorax, and more convex elytra, the latter widest at the middle and narrowing forwards. The differences are too great to admit of its being treated as the male of H. longirostris, the female only of which is known. ‘The present species is also a close ally of the South-American /H. apiatus, Oliv., which is a larger insect and has the elytral spots irregularly scattered over the whole surface, and nowhere ageregated so as to form fasciz. 25. Hilipus guttiger, sp.n. (Tab. II. figg. 12, ¢; 124, profile of head.) Oblong-ovate, shining, piceous or rufo-piceous, the prothorax (except at the base), head, rostrum, and legs sometimes rufous; the prothorax with an ill-defined, narrow, oblique, whitish vitta on each side and for the rest clothed with scattered ochreous pubescence ; the elytra with a broad curved stripe on the outer part of the disc extending from the base to about the middle (in one specimen divided into two), and a very large rounded patch immediately before the apex, the latter extending to the suture, but not to the apical angle, and enclosing a bare spot on the subapical callus, ochreous or pale ochreous, the rest of the surface with scattered, minute, whitish or ochreous scales, which fill up the depressions of the surface and form small spots; the under surface, legs, and rostrum with scattered, narrow, whitish scales. Head foveate between the eyes, which are narrowly separated; rostrum about three-fourths longer than the . HILIPUS. 21 prothorax, feebly curved, moderately stout, thickly punctured towards the base ; antenne inserted far before the middle of the rostrum, joint 1 of the funiculus nearly twice as long as 2. Prothorax broader than long, narrowed in front, and rounded at the sides before the middle; coarsely confluently punctate, and with an incomplete, smooth, raised, median line. Elytra comparatively short, one-half wider than the prothorax, subparallel towards the base, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate, the interstices strongly transversely wrinkled. Length 8-94, breadth 4-44 millim. (¢.) Hab. Mexico, Toxpam (Sallé); Guaremata, Zapote (Champion); Panama, Volcan. de Chiriqui (Champion). One specimen from each locality. This species somewhat resembles Z. rectirostris, H. limbatus, H. elegans, &c.; but has narrow ill-defined prothoracic vittee and trans- versely rugose elytra, the depressions of the surface between the markings being clothed with minute ochreous or whitish scales, so as to form numerous, small, coalescent spots. 26. Hilipus 12-guttatus, sp. n. (Tab. II. figg. 13, ¢; 134, profile of head.). Elongate-ovate, shining, the rostrum and the prothorax and femora in great part rufous; the elytra each with six fulvous spots—one at the base, two in an oblique line on the outer part of the disc before the middle, and three before the apex, the outer anterior one of these in the form of a short curved fascia,— the foves filled with pale ochreous scales; the depressions on the prothorax, as well as the under surface and legs, clothed with whitish scales.

Elytra one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; irregularly seriato-foveate, the fovere here and there transversely confluent, the interstices smooth and shining. Ventral segments 1 and 2 broadly depressed down the middle. Length 11, breadth 43 millim. (¢.) Hab. Nicaraeva, Chontales (Belt). One specimen. An isolated form, distinguishable by its convex rugose prothorax and foveolate elytra, the latter each with six fulvous spots and the fovee filled with pale ochreous scales. Not unlike H. paradorus, Pasc., from Cayenne, but more elongate and with a much shorter rostrum, the eyes not rounded, the femoral tooth sim ple. 27. Hilipus ahrensi. (Tab. II. fig. 14, ¢.-) Heilipus ahrensi, Boh, in Schonh, Gen. Cure. vii. 2, p. 80°. Hab. Mexico, Oaxaca ! (Sal/é). Easily distinguishable from its Central-American allies by the very coarse transverse _ wrinkling of the prothorax and elytra, and the peculiar coloration, the prothorax having two small pale ochreous spots on the disc in front and a large similarly-coloured 22 RHYNCHOPHORA. patch at each of the hind angles, the elytra with various pale ochreous spots, these tending to form a straight, transverse, median, and a curved subapical, fascia. ‘The male has the first ventral segment broadly depressed down the middle. The head is deeply foveate between the eyes. The scrobes are directed downwards, and are separated only by an acute ridge at the base of the rostrum beneath. H. wndabundus, Boh., from Brazil, is very like the present species. 28. Hilipus sexmaculatus, sp.n. (Tab. II. figg. 1, 3; 15a, profile of head.) Elongate-ovate, piceous, the prothorax with a rather narrow whitish vitta on each side; the elytra with a small transverse spot at the shoulders, a short, oblique, angulated fascia at the sides before the middle, and an irregular transverse spot or fascia on the disc before the apex, also white; the depressions on the rest of the upper surface thickly clothed with minute ochreous scales, amongst which on the prothorax some much longer ones are visible; the under surface, head, rostrum, and legs with scattered, narrow, whitish or ochreous scales, the pleura and the sides of the ventral segments 1—4 with patches of whitish scales. Head deeply foveate between the eyes, which are narrowly separated ; rostrum very stout, strongly curved, about one-fourth longer than the prothorax, rugosely punctured, except towards the tip, the scrobes directed downwards and separated only by a narrow ridge at the base ; antennz inserted a little before the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length.

LElytra elongate, one- half wider than the prothorax, flattened on the disc, subparallel towards the base, conjointly rounded at the apex, the humeri rounded ; the entire surface granulate, the granulations here and there transversely confluent. Ventral segments coarsely sparsely punctate, 1 and 2 broadly depressed down the middle in the male. Length 15-164, breadth 53-63 millim. (d 9.) Hab. Guatemaa, Cerro Zunil (Champion). Numerous specimens, varying only in the size of the elytral spots. The upper surface is sculptured very much as in J. albifrons, which, however, is a much narrower insect, with immaculate prothorax and elytra. This is one of many species of Hilipus found by myself in forest-clearings on the Pacific slope of the Cerro Zunil, in the immediate vicinity of the coffee-plantation known as “ Las Nubes.” 29. Hilipus albifrons, sp.n. (Tab. II. fig. 16, ¢ .) Elongate-ovate, rather narrow, pitchy-black, the head with a patch of pale ochreous or whitish scales behind the eyes; the prothorax and elytra covered with small, smooth, shining, granular elevations, which here and there on the elytra are arranged in transverse irregular series, the interspaces dull and densely clothed with minute ochreous scales: the under surface, rostrum, aud legs with scattered, narrow, whitish scales, the ventral segments each with a transverse patch of pale ochreous scales on either side in front. Head densely, rugosely punctured, foveate between the eyes, which are narrowly separated; rostrum very stout, strongly curved, slightly longer than the prothorax, densely, rugosely punctate, except towards the tip, the scrobes directed downwards and separated only by a narrow ridge at the base ; antenne inserted far before the middle of the rostrum, joint 1 of the funiculus slightly longer than 2, Prothorax convex, a little longer than broad, narrowed in front, the sides rounded anteriorly and almost straight behind. Elytra elongate, one-half wider than the prothorax, subparallel at the base, conjointly rounded at the apex, flattened on the disc, the subapical callosities rather prominent, the humeri rounded. Metasternum comparatively elongate, very coarsely confluently punctured at the sides. Ventral segments very sparsely, rather coarsely punctate, the first slightly depressed down the middle in the male. . Length 13-143, breadth 43-5 millim. (¢ 9.) HILIPUS. 23 Hab. Guatemata, Purula in Vera Paz (Champion). Four specimens. A very distinct species, easily identified by the patch of whitish- ochreous scales on the head, the flattened elongate elytra, and the uniformly granulate upper surface. 80. Hilipus empiricus. (Tab. II. figg. 17, ¢; 17a, profile of head; 17 6, rostrum from beneath.) Hilipus empiricus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 71. Hab. Guaremata, Teleman (Champion); Nicaracua, Chontales! (Belé); PANAMA, Caldera in Chiriqui (Champion). We possess six specimens of this peculiar species. Apart from the confluent scrobes *, it is recognizable by the broad, sinuous, sordid ochreous elytral vitte, which extend from the base to the apex (or are occasionally interrupted), leaving two confluent, common, diagonal patches on the disc and a transverse one before the apex, the prothorax also with broad similarly-coloured vitte. The elytra are flattened on the disc, coarsely seriate-punctate; the prothorax is as long as broad, coarsely rugose, and with a smooth median carina; the rostrum is strongly curved and slightly longer than the prothorax; the antenne are inserted before the middle of the rostrum in both sexes; the second joint of the funiculus is slightly shorter than the first; the eyes are narrowly separated above and beneath. ‘The first and second ventral segments are broadly depressed down the middle in the male. H. velamen, Boh., H. tetanicus and H. designatus, Pasc., are allied forms. Secrion II. 31. Hilipus securiger, sp. n. (Tab. II. figg. 18, ¢; 184, profile of head ; 18 6, antenna.) Oblong-ovate, very robust, slightly shining, black, the rostrum and legs more or less piceous; the prothorax sparsely clothed with fulvous piliform scales, these tending to form a narrow, irregular, sinuous vitta on each side of the disc and some spots on the flanks, the scutellum with white scales ; the elytra clothed with brownish-fulvous piliform scales, with very small, irregularly scattered, white or ochreous spots, and an oblong dark brown patch on the fourth interstice at about the middle; the mesepimera with a patch of fulvous scales below the humeri; the under surface and legs with widely-scattered, narrow, whitish scales. Head closely punctured, the eyes large and approximate ; rostrum curved, moderately stout, considerably longer than the prothorax, rugosely punctured in its basal half, the scrobes extending forwards from the points of insertion of the antenne to near the tip; antenne inserted at about the middle of the rostrum in both sexes, joints 1 and 2 of the funiculus subequal in length. Prothorax convex, nearlv as long as broad, bisinuate at the base, rounded at the sides, abruptly constricted and narrowed in front; con- spicuously granulate, with an interrupted, smooth, median carina. LElytra one-half wider than the prothorax, subtruncate at the base, gradually narrowing almost from the shoulders, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate, the interspaces dull, granulate. Lateral portions of the metasternum coarsely foveolate. * A character not noticed by Pascoe. 24 RHYNCHOPHORA. g. First ventral segment, and the metasternum also, very broadly and shallowly depressed down the middle, this space being pilose and closely punctate, and the fifth segment with a transverse depression at the apex. Club of the antenne securiform, and the seventh joint of the funiculus furnished with a cluster of fulvous bristly hairs. Length 14-163, breadth 63-73 millim. (d 2.) Hab. Guaremata, Cubilguitz in Vera Paz (Champion) ; Nicaragua, Chontales (Belt, Richardson). Two males and three females. A large robust species, distinguishable by the irregularly-scattered, minute, white or ochreous spots on the elytra, the approximate eyes, the convex granulated prothorax, and peculiar male-characters. The lateral grooves of the rostrum (scrobes) extend forwards beyond the points of insertion of the antenne to near the tip. This character, alone, will separate H. securiger from the following nearly allied form. The oblong, blackish, velvety patch on the fourth elytral interstice is not easily seen in abraded specimens. The abnormally-formed antennal club of the male is a very remarkable peculiarity. 32. Hilipus nigrofasciatus, sp. n. (Tab. II. figg. 19, ¢; 194, profile of head.) Oblong-ovate, robust, slightly shining, black or piceous; the prothorax variegated with fulvous scales, the scutellum and a spot below the humeri densely clothed with white scales, the elytra variegated with fulvous and blackish scales, the latter forming a broad, irregular, angulated, transverse fascia a little beyond the middle, the edges of this being here and there indicated by scattered small pure white spots, which are variable in number, all the scales narrow and piliform; the under surface and legs with scattered, narrow, whitish scales. Head closely punctured, the eyes large and contiguous; rostrum curved, moderately stout, considerably longer than the prothorax, thickly punctured towards the base, smooth towards the tip; antenne inserted at about the middle of the rostrum in both sexes, joints 1 and 2 of the funiculus subequal in length. Prothorax considerably broader than long, convex, bisinuate at the base, rounded at the sides, abruptly constricted and narrowed in front; sparsely and finely granulate, with a more or less distinct, smooth, raised, central line. Elytra convex, about one-half wider than the prothorax, gradually narrowing from a little below the base, conjointly rounded at the apex, the humeri rounded; deeply seriate-punctate, the interspaces dull, obsoletely or finely granulate. Lateral portions of the metasternum coarsely foveolate. ¢. First ventral segment, and the metasternum also, very broadly and shallowly depressed down the middle, this space being pilose and closely punctate, and the fifth segment with a transverse depression before the apex.

A common species within our limits, extending to Northern Mexico and occurring on both the Atlantic and Pacific slopes. Distinguishable by its broad short form and the peculiar maculation of the upper surface, the prothorax having a large ochreous patch at the sides in front and the elytra a similarly-coloured one on the disc before the apex, and both, in addition, with numerous, scattered, white spots, those on the middle of the disc of the prothorax and on the base and anterior portion of the elytra being the most conspicuous. The eyes are almost contiguous above; the rostrum in the male is short, stout, rugosely punctured, and carinate, it being smoother and more slender in the female; the first and second joints of the funiculus are equal in length ; the scutellum is without white scales; and the metasternum is almost smooth. The first ventral segment is narrowly sulcate down the middle from the base to the apex in the male. H. multiguttatus (Fabr.) is a nearly-allied form, having the ochreous patches on the prothorax and elytra replaced by white spots. 34, Hilipus leucostictus, sp. n. (Tab. II. figg. 21, ¢; 21a, profile of head.) Oblong-ovate, subopaque, black or piceous, the legs and rostrum usually reddish; the upper surface clothed with brownish-ochreous piliform scales, the elytra sometimes variegated with blackish ones; the pro- thorax with two white spots on the disc and one on each side in front, and the elytra each with five conspicuous white spots—four in an oblique series on the disc, extending from the base to near the apex (the third the largest, and the second and fourth sometimes obsolete or indistinct), and one at the side below the base,—and often a few other smaller ones scattered along the outer margin posteriorly and on disc, the scutellum also with white scales; the under surface clothed with narrow ochreous and whitish scales, the pleura sometimes with white spots; the legs with whitish scales. Head closely punctured, the eyes contiguous; rostrum not very stout, curved, much longer than the prothorax, finely punctured towards the base; antenne inserted a little before the middle of the rostrum, joint 2 of the funiculus slightly longer than 1. Prothorax a little broader than long, convex, strongly rounded at the sides and narrowed in front, feebly bisinuate at the base; sparsely granulate and with an abbreviated median carina. Elytra one-half wider than the prothorax, truncate at the base, subparallel before the middle, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate, the punctures deep and transverse, the interstices narrow and in some specimens finely granulate. Metasternum coarsely foveolate at the sides. Ventral segment 1 depressed along the middle in the ¢. Anterior and inter- mediate tibize curved. Length 10-113, breadth 43-5 millim. (d¢ 9.) Hab.

Very like HW. multiguttatus (Fabr.) and H. guttatus, Boh., but with the elytra truncate at the base and the white spots differently placed, the four on the disc being almost equidistant and arranged in an oblique line. The single specimen from Chiapas has the elytra variegated with blackish scales and the second white spot in the discoidal series absent. 35. Hilipus chiriquensis, sp. n. (Tab. II. fig. 22, ¢ .) Very like H. leucostictus and differing as follows :—The eyes separated by a narrow space, the rostrum more coarsely punctured towards the base, the prothorax less rounded at the sides and much more sparsely granulate, with a longer and more distinct median carina, the serrate punctures on the elytra rounded (instead of transverse) and more scattered ; the prothorax with six very small white spots—two on the dise, one on each side in front and one on each flank; the elytra with a small white spot on the fourth interstice below the base (absent on the left elytron), several others (five or six on each elytron) a little beyond the middle, these forming an irregular, common, transverse fascia, and a larger one at the sides a short distance below the humeri. Length 10, breadth 43 millim. (<¢.) Hab. Panama, Volcan de Chiriqui (Champion). One specimen. Perhaps an extreme form of H. leucostictus, differing, however, in the sculpture of the prothorax and elytra, as well as in the arrangement of the white spots. 36. Hilipus rotundicollis, sp.n. (Tab.

Oblong-ovate, dull, black, the legs and rostrum piceous or nigro-piceous; the upper surface clothed with brownish-fulvous piliform scales, the prothorax with two small whitish or pale ochreous spots on the disc before the middle and one on each side in front, and the elytra with several small similarly-coloured spots —one at the base near the shoulder, two (obliquely placed) on the flanks some distanee below the base, one on the fourth interstice a little beyond the middle, and some others along the outer margin, being the most distinct,—and each with two velvety-black patches on the disc—one at the middle, subquadrate, the other towards the apex, irregular, and formed by two interrupted coalescent streaks,—the scutellum clothed with pale ochreous scales; the under surface with narrow fulvous, and the legs with whitish, scales. Head closely punctured, the eyes approximate; rostrum comparatively slender, curved, about one-half longer than the prothorax in the ¢, a little shorter in the 2, thickly punctured to the middle and smooth beyond ; antenne inserted at the middle of the rostrum, joint 2 of the funiculus slightly longer than 1. Prothorax convex, a little broader than long, strongly rounded at the sides almost from the apex to the base, abruptly constricted and narrowed in front; granulate and with a smooth median carina. Elytra rather short, one-half wider than the prothorax, gradually narrowing from a little below the base, which is subtruncate, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate and very finely granulate, the interspaces dull.

British Hoypuras, Rio Sarstoon (Blancaneauz). One pair. Closely allied to H. leucostictus and H. chiriquensis, both of which have similarly-placed whitish spots on the prothorax; but differing from these insects in having two velvety-black patches on the disc of each elytron, placed one behind the other, as well as in the very small size and position of the whitish spots. The — HILIPUS. aT prothorax is even more rounded at the sides than in H. leucostictus, and the elytra are less elongate than in that species. 37. Hilipus rusticus. Heilipus rusticus, Boh. in Schénh.

We possess thirteen specimens of this species, distinguishable by its large size, the scattered series of smooth, prominent, conical tubercles on the elytra, the apices of the latter being separately acuminate and the subapical callosities prominent, the sparsely tuberculate, carinate prothorax, &c. The rostrum is longer than the prothorax, stout, closely punctured towards the base, and has a short longitudinal groove between the points of insertion of the antenne. The latter are inserted far before the middle of the rostrum; the second joint of the funiculus is, at most, a little longer than the first *. The head is deeply foveate between the eyes. ‘The elytra have a large, sub- triangular, black or brown, velvety patch on the disc about the middle, but this is not always visible in old or dirty specimens and it is not mentioned by Pascoe. ‘The males have the first ventral segment depressed in the centre. 39. Hilipus spiculosus, sp. n. (Tab. II. fig. 25, ¢.) Oblong-ovate, opaque, black, the antennw and tarsi rufo-piceous; the prothorax and elytra densely clothed with brown scales, the elytra each with a small, elongate-triangular, velvety-black patch on the disc, the scutellum, rostrum, legs, and under surface with whitish pilitorm scales. Head shallowly foveate between the eyes, which are somewhat narrowly separated ; rostrum stout, feebly curved, a little longer than the prothorax, rugosely punctured in its basal half ; antenne inserted before the middle of the rostrum, joint 2 of the funiculus slightly longer than 1. Prothorax convex, transverse, rounded at the ‘sides, constricted and narrowed in front, strongly bisinuate at the base ; sparsely tuberculate, each of the elevations bearing a short decumbent seta in front, faintly carinate down the middle. Elytra one-half wider than, and nearly three times the length of, the prothorax, sinuato-truncate at the base, subparallel anteriorly, conjointly rounded at the apex, which is slightly emarginate at the suture, the humeri somewhat angulate externally ; the surface very uneven, coarsely seriate-punctate, the interstices with numerous, scattered, irregularly-arranged, smooth, conical tubercles, those on the disc large and prominent, each bearing a * Never twice as long, as stated by Pascoe.

Hab. Nicaracua, Chontales (Belt). One specimen. Allied to the South-American H. muricatus and H. tuberculatus, but not agreeing with the descriptions of those species. From H. phrynodes it may be known by its much smaller size, the shorter rostrum, the more convex, more closely tuberculate, and obsoletely carinate prothorax, the shorter elytra, the apices of which are very feebly emarginate, &c. H. aspredo, Pasc., is also a very similar form. 40. Hilipus frontalis. (Tab. II. fig. 26, ¢.) Hilipus frontalis, Pasc. Trans. Ent. Soc. Lond. 1889, p. 586, t. 17. fig. 5°. Hab. Nicaracua, Chontales 1 (belt). Recognizable by the coarsely tuberculate prothorax and elytra, the latter each with two rounded patches of ochreous scales (one at the base close to the shoulder, and the other some distance beyond the middle near the suture), the head also with a large rounded patch of similarly-coloured scales. The rostrum is very stout, a little longer than the prothorax, and coarsely foveolate on the basal half. The antenne are inserted before the middle of the rostrum; the second joint of the funiculus is slightly longer than the first. The eyes are somewhat widely separated. The male has the first ventral segment deeply sulcate down the middle behind. Two specimens only have been received by us, both of this sex. 41. Hilipus appendiculatus, sp.n. (Tab.

Differs from the other Central-American species of the genus in the form of the hind tibie of the male, these being strongly sinuous and produced at the inner apical angle into a flattened, spoon-shaped process, the usual claw being entirely absent in this sex. All the tibiee have two long, matted, spine-like pencils of hair at the apex. The velvety-black spot on each elytron is more obliquely placed than in any of the other similarly-coloured Hilip: inhabiting our region. 42. Hilipus suspensus. (Tab. III. figg. 1, 1a, 2.)

This is a species with velvety-black markings on the prothorax and elytra, there being a sinuous streak on either side of the disc of the former, and an elongate patch of variable extent on the disc of each of the latter (this being often broken up and reduced to narrow streaks), the elytral markings extending more or less posteriorly so as to include the various fulvous or whitish discoidal spots; the prothorax has a fulvous stripe on each side exterior to the black one, and on the flanks there is a large, sinuous, white-edged, fulvous patch ; the scutellum is clothed with white scales; the elytra have each a small fulvous spot at the base and an oblique white patch on the outer margin below the shoulder; the rest of the upper surface is thickly clothed with minute, narrow, chocolate-brown scales. The rostrum is curved, closely punctured from the base to the apex, moderately stout and considerably longer than the prothorax in the male, longer and more slender in the female. The head is not foveate between the eyes, which are narrowly separated. The first and second joints of the funiculus are subequal in length. ‘he disc of the prothorax and the base of the elytra are obsoletely granulate. The first ventral segment is unimpressed in both sexes. 43. Hilipus pulchellus, sp. n. (Tab. III. fig. 2, 2.)

Head not or faintly foveate between the eyes, which are rather narrowly separated ; rostrum curved, closely punctured to the tip, a narrow space along the middle excepted, very stout and considerably longer than the prothorax in the ¢, longer and a little more slender in the 2, the apex shining ; joint 2 of the funiculus longer than 1. Prothorax slightly broader than long, moderately rounded at the sides, bisinuate at the base, narrowed and constricted in front, sparsely granulate. Elytra one-half wider than the prothorax, flattened along the suture anteriorly, gradually narrowing from the base, the apices conjointly rounded, the humeri rounded externally and slightly hollowed in front, the third interstice somewhat costate towards the base; seriate-punctate and sparsely granulate, each of the smooth elevations bearing a short decumbent seta behind. First ventral segment somewhat deeply depressed along the middle behind in the male. Length 123-133, breadth 53-6 millim. (d @.) Hab. Nicaragua (Sallé), Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion).

Nicaraaua, Chontales (Belt, Janson); Panama, Bugaba (Champion).—Sovutu America !, Cayenne ?, Bolivia ?, &c. This species may be recognized by the large velvety-black mark on the disc of each elytron, this being triangular in shape and extending downwards at the inner angle, often meeting a similarly-coloured longitudinal streak on the third interstice, followed by a large ochreous or greyish evanescent patch. ‘The head is shallowly canaliculate between the eyes. The rostrum is short and broad, carinate, and not longer than the prothorax; the scrobes are lateral and in great part visible from above. The prothorax has a narrow oblique line of greyish or ochreous scales on each side of the disc. The males have a dense transverse patch of ochreous scales (sometimes divided into two) at the middle of the posterior margin of the first ventral segment, which is unimpressed in both sexes. The South-American specimens I have seen are considerably larger than any of the nine obtained in our region. 45. Hilipus exustus. (Tab. III. fig. 4, 2.) Hilipus exustus, Pasc. Trans. Ent. Soc.

The rostrum is very stout, about as long as the prothorax. The second joint of the funiculus is very little longer than the first *. The head is obsoletely foveate between the eyes, which are rather narrowly separated. ‘The tibie have a triangular tooth at the middle and an acute one at the inner apical angle, and the terminal hook is long and sharp. The males have a slightly shorter rostrum than the females and the first ventral segment depressed along the middle. Nine specimens have been seen from within our limits. 46. Hilipus cynicus. (Tab.

The fourteen specimens received of this species show considerable variation in the size and shape of the large velvety-black patch on the disc of each elytron, and also in the extent of the encircling ring of ochreous or ashy scales: in four (out of the seven) examples obtained north of Nicaragua the black patch is reduced in size, rounded, and with, at most, a faint line of ashy scales round it; in the two individuals from Chiriqui, as in some of those from Chontales, the black patch is very large and angular, and encircled (except on the outer edge) by a rather broad line of ochreous scales. In fresh specimens there is an angulated line of ochreous or greyish scales on each side of the disc of the prothorax. The rostrum is very stout, the antenne inserted near the tip; the eyes are somewhat distant; the prothorax and elytra are granulate ; the first ventral segment is flattened or very faintly depressed in the middle in the male. A typical specimen from Nicaragua is figured. 47, Hilipus intensus, (Tab. III. fig. 6, ¢.) Hilipus intensus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 79°. Hab.

Recognizable by the very large, posteriorly excised, velvety-black patch on the disc of each elytron beyond the middle, this patch bordered with a narrow line of ochreous scales, and sometimes followed by a small triangular one. The rostrum is stout, feebly curved, considerably longer than the prothorax in the male, smoother at the apex and still longer in the female, rugose and 5-carinate towards the base. The head is sulcate between the eyes, which are very narrowly separated. The prothorax and elytra are sparsely granulate, each of the smooth, tuberculiform, elytral elevations bearing a short decumbent seta; they have the surface clothed (except upon the velvety patch) with minute, rounded, brownish scales. The scutellum is clothed with whitish scales. The males have the metasternum and first ventral segment very broadly and shallowly depressed down the middle. 48. Hilipus flavolineatus, sp. n. (Lab. III. figg. 7, 2; 7a, profile of head.) Oblong-ovate, opaque, black, somewhat thickly clothed with very minute, rounded, brown scales; the elytra each with a very large, oval, velvety-black, lateral patch, extending inwards to near the second row of punctures and limited internally by a line of pale ochreous scales, which is continued forwards round the humeri to the base of the sixth interstice, the scutellum also clothed with pale ochreous scales ; the under surface and legs very sparsely clothed with piliform ochreous scales. Head foveate between the eyes, which are rather widely separated ; rostrum dull, strongly curved, stout, considerably longer than the prothorax, sparsely, finely punctate, smoother towards the tip, with a smooth narrow space down the middle; antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, convex, rounded at the sides, abruptly constricted and narrowed in front, very sparsely granulate, the elevations transverse and not very prominent. Elytra one-half wider than the prothorax, sinuate at the base, subparallel to near the middle, conjointly rounded at the apex, but with the sutural angles somewhat pointed, the humeri rounded externally and concave in front; finely seriate-punctate, the punctures becoming coarse towards the base, the interstices (except upon the velvety patch) with a single, widely-scattered, irregular series of rather prominent granular elevations, each of which bears a short decumbent seta on its posterior edge. Metasternum very sparsely foveolate towards the sides. Ventral surface almost smooth, the first segment unimpressed. Length 11-12, breadth 5-53 millim. (@.) Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). Two specimens. Not unlike the South-American H. zoubkofii, H. ocellatus, &c., but with the velvety-black patch on each elytron very large and lateral, the interstices each with a single series of scattered, setigerous, granular elevations. From H. intensus, which has similar minute scales on the upper surface, it may be distinguished by the more curved non-carinate rostrum, the much larger and differently-shaped velvety patches on the elytra (which are not bordered externally with a line of ochreous scales), the more widely separated eyes, &c. 49. Hilipus nigromaculatus, sp.n. (Tab III. fig. 8.) Oblong-ovate, slightly shining, black, thickly clothed with narrow brown scales; the elytra each with a very large, oval, velvety-black, lateral patch, extending inwards to about the second row of punctures and limited internally by a line of ochreous scales; the under surface and legs sparsely clothed with piliform whitish or ochreous scales.

Prothorax convex, broader than long, moderately rounded at the sides, feebly constricted and much narrowed in front, sparsely granulate. Elytra one-half wider than the prothorax, sinuate at the base, subparallel to near the middle, conjointly rounded at the apex, the humeri rounded; seriate-punctate and finely granulate, the interstices transversely wrinkled towards the base. Length 10-114, breadth 43-53 millim. Hab. Mexico, Jalapa ({Hége); Panama, Bugaba, Volcan de Chiriqui (Champion). Three specimens, probably including both sexes. Very like H. flavolineatus, but slightly shining, the prothorax a little less constricted in front and more finely granulate, the elytra more closely and not so coarsely granulate, with the humeri less hollowed in front, the velvety-black patches less elongate, and the line of ochreous scales bordering them internally not extending sinuously forward to the base, the brownish scales on the prothorax and elytra more elongate. 50. Hilipus decoratus, sp.n. (Tab. III. fig. 9, ¢.) Oblong-ovate, opaque, black, the upper surface thickly clothed with griseous and brown scales, the latter usually forming two obscure vitte on the disc of the prothorax and various spots on the disc of the elytra, each elytron with a large rounded or rounded-triangular velvety-black. patch on the outer part of the disc and a similarly-coloured triangular mark near the suture before the apex ; the under surface thickly squamose, the legs with piliform scales. Head not or feebly sulcate between the eyes, which are somewhat widely separated; rostrum stout, in the ¢ slightly curved, about as long as the prothorax, and closely punctured and laterally sulcate towards the base, in the 2 longer, more curved, and smoother at the tip; joint 2 of the funiculus slightly longer than 1. Prothorax broader than long, rounded at the sides, narrowed in front, very sparsely granulate, the granules larger on the disc than on the flanks. Elytra a little more than one-half wider than the prothorax, gradually narrowing from the base, the latter sinuato-truncate, conjointly rounded at the apex, the humeri swollen, rounded externally; the surface uneven, the third interstice interruptedly costate and the subapical callosities prominent, seriate- punctate, the interstices with widely-scattered, smooth, prominent tubercles, each of these bearing a short, pallid, decumbent seta. 3. First ventral segment hollowed down the middle, the depression limited on either side posteriorly by a dense cluster of ochreous scales, and the fifth with a deep transverse sulcus on each side before the apex. Length 8-9, breadth 33-4 millim. (¢ @.) Hab. Guatemata, Sinanja, Panima and Senahu in Vera Paz (Champion). Five examples, all from the vicinity of the Polochic Valley. This species appears to be a near ally of H. muricatus, Boh., from Colombia, but it does not fully accord with the description of that insect, nor with a specimen thus named in the British Museum. It is also very similar to H. prodigialis, Germ., from Brazil, but is much smaller and the black patch on the elytra is not emarginate behind as in that species. The fifth ventral segment in the male has a deep transverse groove towards the apex, which is interrupted in the middle, whereas in the female the groove is shallow and uninterrupted. 51.

Prothorax transverse, rounded at the sides, strongly bisinuate at the base, constricted and narrowed in front, granulate, and sometimes with traces of an abbreviated median carina. Elytra one-half wider than the prothorax, parallel towards the base, the latter sinuate, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate, and in some specimens finely granulate, the interstices smooth and transversely wrinkled.

Specimens of the form here selected as typical of this species are labelled Z. circu liferus, Jekel, in the Sallé collection. In Guatemala the variety, which seems to be the Hilipus described by Boheman under the preoccupied name of H. biplagiatus, is confined to the Pacific slope, and was found in plenty at Zapote, and the typical form to the Atlantic slope. H. biplagiatus, Boh., which looks very distinct at first sight, merely differs from H. circuliferus in having the velvety-black spot on the disc of the elytra reduced in size, or broken up into spots, and not encircled by a line of greyish or ochreous scales. Of the forty specimens before me, twenty-two belong to the former. From H. cynicus the present species may be separated by its much smaller size, the less prominent humeri, &c. 52. Hilipus atrosignatus, sp.n. (Tab. III. fig. 12.) Oblong-ovate, subopaque, black, the head, rostrum, and legs rufo-piceous, the antennee and tarsi rufescent ; the upper surface variegated with whitish and brown scales, the whitish ones forming a short median and a sinuous submarginal line on the prothorax, a spot on the scutellum, and a line round the large, rounded, velvety-black patch on the disc of each elytron, the latter also with a small velvety-black spot on the subapical callus; the under surface and legs sparsely clothed with whitish and ochreous piliform scales. Head foveate between the eyes, which are rather narrowly separated; rostrum stout, feebly curved, a little longer than the prothorax, thickly punctured and laterally sulcate towards the base ; joint 2 of the funiculus slightly longer than 1. Prothorax transverse, strongly bisinuate at the base, rounded at the sides, constricted and narrowed in front; sparsely, coarsely granulate, Elytra rather HILIPUS. 35 short, one-half wider than the prothorax, parallel towards the base, conjointly rounded at the apex, the humeri rounded externally and hollowed in front; seriate-punctate and sparsely, coarsely granulate, the smooth granular elevations each bearing a short decumbent seta. First ventral segment un- impressed. Length 93, breadth 44 millim. Hab. Nicaragua, Chontales (Belt). One specimen, probably a male. A second example (?%), found by myself at Bugaba, Panama, belongs to this or to a very closely-allied species. It differs from the Nicaraguan insect in having the prothorax and elytra much more finely granulate, the interstices of the latter transversely wrinkled towards the base, the rostrum mote elongate. 53. Hilipus asperatus, sp.n. (Tab. III. fig. 13.) Oblong-ovate, black, the head, rostrum, antenne, and legs rufo-piceous ; the prothorax and elytta somewhat thickly clothed with intermixed fulvous and whitish scales, the whitish ones on the prothorax coarse and piliform, the elytra each with a triangular, brownish-black, velvety patch on the disc and a transverse similarly-coloured streak near the apex; the scutellum with whitish scales; the under surface and legs sparsely clothed with ochreous and whitish piliform scales. Head foveate between the eyes, which are rather narrowly separated; rostrum short and very stout, feebly curved, very little longer than the prothorax, towards the base rugosely punctured and laterally sulcate; joints 1 and 2 of the funiculus subequal in length. Prothorax convex, much broader than long, rounded at the sides, considerably narrowed in front, strongly bisinuate at the base, coarsely granulate, without trace of median carina. Elytra comparatively short, one-half wider than the prothorax, sinuate at the base, gradually narrowing from a little below the humeri, the latter rounded externally, the apices conjointly rounded; the surface uneven, coarsely seriate-punctate, the interstices with scattered series of smooth tubercles, those on the third interstice large, each bearing a rather long decumbent seta, the subapical callosities prominent, Ventral segments 1-4 very sparsely, minutely punctate, the first unimpressed. Length 9, breadth 4 millim. Hab. Guaremaua, Cubilguitz in Vera Paz (Champion). One specimen, no doubt a male, the rostrum being very short. Recognizable by the coarsely tuberculate, transverse thorax, the rather stout, tuberculate, setigerous elytra, each of which has a small triangular, dark, velvety patch on the disc, &c. Compared with H. spiculosus it is less elongate and much smaller, the elytra are narrower and more finely tuberculate, the tubercles on the prothorax, on the contrary, being larger. 54. Hilipus costaricensis, sp. n. (Tab. III. fig. 14.) Oblong-ovate, black, shining, the rostrum and the legs in part piceous, the tips of the tarsi and the scape rufescent ; the upper surface variegated with rather coarse, narrow, ochreous and whitish scales, the elytra each with a very large, black, subtriangular, lateral patch (extending from a little below the shoulder to near the tip, and inwards to the third interstice) and a small transverse black mark before the apex ; the legs and under surface with scattered, coarse, piliform, whitish and ochreous scales. Head closely punctate, not foveate between the eyes, the latter large and somewhat narrowly separated ; rostrum moderately stout, feebly curved, much longer than the prothorax, shining, sparsely punctate ; antenne inserted considerably before the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax convex, transverse, rounced at the sides, constricted in front, and FF 2 36 RHYNCHOPHORA. strongly bisinuate at the base; the surface coarsely granulate, the elevations smooth and shining and transverse in shape on the disc, in the centre of which is a smooth oblong prominence. Elytra one-half wider than, and three times the length of, the prothorax, subtruncate ,at the base and subparallel thence to the middle, flattened on the disc anteriorly, the humeri rounded, the subapica callosities prominent, the apical portion somewhat abruptly declivous, the apices conjointly rounded ; deeply seriate-punctate, the interstices slightly convex and each with a scattered series of smooth tubercles.

Legs comparatively short; tibisze mucronate, the claw arising from near the outer angle. Length 83, breadth 4 millim. (2.) Hab. Costa Rica, Pital del Naranjo (Biolley, in Mus. Brit.). Two specimens. This species is perhaps nearest allied to H. asperatus, H. nevulus, and If. atrosignatus, but has relatively shorter and broader elytra, the black patch very large and laterally placed, a long rostrum, &c. The shorter prothorax, more parallel elytra, &c., separate it from H. decoratus. The white scales on the upper surface are chiefly confined to a space on the disc of the elytra beyond the middle, the scutellum, and a line down the middle of the prothorax. 55. Hilipus trinotatus, sp.n. (Tab. III. figg. 15; 15, profile of head &c.) Elongate-ovate, black, the prothorax (except along the middle in front), scutellum, and elytra densely clothed with flavo-cinereous scales, the disc of the prothorax and of that of the basal half of the elytra mottled with brown, the elytra with a very large, subtriangular, sharply-defined patch at the sides a little beyond the middle and a common apical patch brownish-black ; the head, rostrum, under surface, and legs sparsely clothed with piliform greyish scales.

Elytra comparatively elongate, subparallel in their basal half, one-fourth wider than the prothorax, flattened on the disc, conjointly rounded at the apex, but with the sutural angles somewhat pointed, the humeri rounded; coarsely seriate-punctate, the interstices narrow, transversely rugose, and also very sparsely but conspicuously granulate. First ventral segment faintly depressed in the middle behind. ‘Tibia acutely mucronate, the curved apical claw also long. Length 133, breadth 5 millim. Hab. Nicaracva, Chontales (Belt). One specimen, probably a female. A very distinct species, not unlike H. jocosus, but more elongate, densely squamose (the scales completely hiding the sculpture, with the exception of the smooth granular elevations), the antenne stouter, with a shorter club, the prothorax more rounded at the sides, the anterior tibie strongly mucronate at the tip, &c. 56.

The entire upper surface is sparsely granulate, the elytra flattened towards the suture. In the males the first ventral segment is slightly emarginate at the apex, and furnished with a dense patch of ochreous and brown seales in the centre behind, the other scales on the ventral surface being white. 57. Hilipus quadrinodosus, sp. n. (Tab. ITI. figg. 17, ¢ ; 17 a, profile of elytra.) Oblong-ovate, dull, piceous, more or less mottled with black, the upper surface variegated with a somewhat: dense clothing of rather coarse whitish and fulvous scales, the elytra also with intermixed dark brown scales and with a transverse series of small velvety-black streaks on the dise at about one-third from the apex, that on the fifth interstice the longest; the under surface and legs with whitish and fulvous scales, those on the pleura coarse and closely placed. Head rugosely punctured, not foveate between the eyes, which are somewhat narrowly separated; rostrum very stout, not longer than the prothorax, feebly curved, rugosely punctured; joints 1 and 2 of the funiculus subequal in length. Prothorax convex, broader than long, rounded at the sides, narrowed and constricted in front, strongly bisinuate at the base; granulate, the elevations coarser and more transverse on the disc than at the sides. Elytra one-half wider tham the prothorax, subparallel in their basal half, strongly sinuate: at the base, conjointly rounded at the apex, the humeri rounded; coarsely seriate-punctate and conspicuously granulate, the interstices transversely wrinkled, the third shortly costate at about one-third from the apex and then abruptly declivous, the blunt tooth thus formed being as prominent as the subapical callus, these elevations limiting the flattened space on the apical declivity. Metasternum transversely strigose. Ventral segments finely, shallowly punctate, the first sometimes notched in the centre of the apical margin. _ Length 114-123, breadth 53-53 millim. (d @-) Hab. Guatemata, Rio Maria Linda, Pacific slope (Champion) ; Nicaragua, Chontales (Belt). Four specimens. Not unlike H. jocosus, but less elongate and relatively broader ; the elytra more coarsely granulate, with the third interstice raised into a blunt tooth posteriorly, and the velvety-black markings consisting of a transverse series of three or four small streaks on the disc at about one-third from the apex, the streak on the fifth interstice being longer than the others; the metasternum transversely strigose. The quadrinodose apical declivity of the elytra separates the present species from the other allied Central-American forms. 38 RHYNCHOPHORA. 58. Hilipus lutosus. (Tab. III. fig. 18, ¢.)

Very like /. jocosus, but less elongate, the eyes somewhat narrowly separated, the prothorax more transverse, the elytral markings very different, &c. The common, subapical, white fascia on the elytra is broad and sharply limited in front, and usually preceded by a transverse patch of blackish scales. There is also a broad dense band of white scales extending along the pro- and mesopleura, this being partly visible from above. The rest of the squamosity is fine and rather sparse. The type is immature, and has the legs red, with a black patch at the apex of the femora. 59. Hilipus quadrisignatus, sp. n. (Tab. III. fig. 19.) Oblong-ovate, black, the tarsi rufescent ; the prothorax and elytra with the interspaces between the smooth shining tubercles thickly clothed with rather coarse, whitish, ochreous, and fulvous scales, the elytra each with a conspicuous, moderately large, transverse, velvety-black patch on the disc about the middle and an oblong one near the suture before the apex, these markings edged with fulvous scales ; the head, scutellum, under surface, and legs with ochreous scales, the squamosity of the under surface coarse and rather close.

Nicaragua, Chontales (Belt). Three specimens. Distinguishable by the two conspicuous velvety-black patches on each elytron—one median, transverse; the other oblong and subapical. From H. jocosus and other allied species it may be recognized by the numerous, smooth, small, shining tubercles on the prothorax and elytra, the variegate and rather coarse squamosity, and the shape of the velvety-black patches on the elytra. 60. Hilipus nevulus. (Tab. III. fig. 20.) Heilipus nevulus, Mann. in Schénh. Gen. Cure. iii. p. 188°. Oblong-ovate, shining, nigro-piceous or black; the upper surface between the smooth granular elevations variegated with a somewhat dense clothing of narrow, coarse, whitish and fulvous scales, the elytra also with intermixed blackish scales and with an oblong, conspicuous, velvety-black patch on the fourth interstice beyond the middle; the under surface sparsely clothed with coarse, narrow, whitish or ochreous scales, the legs with whitish piliform scales. Head densely punetured, foveate between the eyes, which are somewhat widely separated ; rostrum stout, shining, moderately curved, a little longer than the head and prothorax united, closely punctured towards the base ; joints 1 and 2 of the funiculus equal in length. Prothorax transverse, rounded at the sides, narrowed and constricted in front; sparsely, rather coarsely granulate, the elevations transverse or oblique, and with a smooth, abbreviated, median carina. lytra one-half wider than the prothorax, feebly sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; coarsely seriate-punctate and conspicuously granulate, the interstices transversely wrinkled towards the base, the third very slightly raised to about the middle, the sutura] region appearing flattened. Beneath sparsely, finely punctate, the sides of the metasternum and the fifth ventral segment foveolate, the first segment unimpressed. Length 10-11, breadth 4443 millim. Hab. Panama, Volcan de Chiriqui (Champion).—BraziL, Minas Geraes 1. Two specimens, probably females, agreeing very nearly with the description and with Brazilian examples thus named in the British Museum (from Jekel’s collection). ‘The present species is recognizable by the oblong velvety-black patch on the fourth elytral interstice, the long rostrum, the granulate upper surface, &c. 61. Hilipus decussatus, (Tab. IIL. fig. 21.) Heilipus decussatus, Boh. in Schénh. Gen. Cure. vil. 2, p. 93°. Hab. Mexico (coll. Chevrolat !), Toxpam (Saldé). — In this species the prothorax has an oblique, angulated, white vitta on each side of the disc, and the elytra have a common, interrupted, X-shaped, white mark (extending from the humeri to the subapical callosities), and outside this a large, subtriangular, velvety-black patch. The upper surface is conspicuously granulate. The antenne are inserted a little before the middle of the rostrum, which is long and curved, and. closely punctured to the tip; the second joint of the funiculus is 4() RHYNCHOPHORA. much longer than the first. The two specimens received appear to be male and female. 62. Hilipus adustus, sp. n. (Tab. III. fig. 22, ¢.) Elongate-ovate, opaque, black, the rostrum and antenne piceous, the legs partly rufescent; the prothorax and elytra densely clothed with minute fulvo-cinereous and reddish-brown scales, the elytra variegated with black spots and streaks and the prothorax with a small, triangular, black mark on each side of the disc; the under surface densely squamose, the head and legs with piliform scales. Head foveate between the eyes, which are rather narrowly separated; rostrum moderately stout, feebly curved, a little longer than the prothorax, densely punctate; antenne inserted before the middle of the rostrum, joints 1 and 2 of the funiculus equal in length. Prothorax broader than long, transversely convex, uneven, moderately rounded at the sides, narrowed and constricted in front, bisinuate at the base ; very sparsely and finely granulate, and with a distinct prominence on each side of the disc. Llytra one-half wider than the prothorax, narrowing from a little below the base, conjointly rounded at the apex, the base subtruncate, the humeri rounded; the surface uneven, seriate-punctate, the interstices with scattered, small, smooth granules, the third, fifth, and seventh interruptedly costate. First ventral segment with a smooth, triangular, glabrous space in the middle behind. Tibie sharply mucronate at the inner apical angle, the hind pair strongly bisinuate within, so as to appear triangularly dilated at the middle. Length 18, breadth 5 millim. (¢.) Hab. Mexico, Cerro de Plumas (f/0ge). One specimen. This insect seems to be allied to the Brazilian H. leoninus, Boh. The following species, H. lentiginosus, is not unlike it, and has similar male-characters. The tibial claw in both sexes arises from near the outer apical angle, the tibie thus being ‘“ unguiculate” (instead of “ mucronate”), in the sense of Lacordaire. 63. Hilipus lentiginosus, sp. n. (Tab. III. figg. 28, 9 ; 23a, profile of head.) Oblong-ovate, black, the head, rostrum, legs, and antenne rufo-piceous; the prothorax and elytra variegated with a dense clothing of small fulvous and whitish scales, the latter forming an irregular patch on the disc of the prothorax and another on each flank, and an oblique fascia on the disc of each elytron before the middle and a transverse one beyond it, the elytra also with a curved, longitudinal, velvety-black streak on the disc between the fascie and some similarly-coloured marks near the apex; the scutellum with whitish scales ; beneath thickly squamose, the legs with fulvous and whitish piliform scales. Head foveate between the eyes, which are rather narrowly separated; rostrum not very stout, shining, feebly curved, finely and rather closely punctate towards the base, a little longer than the prothorax in the ¢, considerably more elongate in the 2 ; joints 1 and 2 of the funiculus subequal in length. Prothorax broader than long, transversely convex, rounded at the sides, constricted and narrowed in front, strongly bisinuate at the base, sparsely and rather coarsely granulate. Elytra one-half wider than the prothorax, gradually narrowing from a little below the humeri, which are rounded, the base sinuate, the apices conjointly rounded ; seriate-punctate, the interstices each with a scattered series of rather prominent, smooth, granular elevations. First ventral segment in the g with a smooth, transverse, glabrous space in the middle at the apex, this being preceded by a dense patch of scales. Tibize mucronate, the hind pair strongly bisinuate within. Length 10-12, breadth 47-5 millim. (¢ 9.) Ilab. Nicaracva, Chontales (Janson); Panama, Bugaba (Champion). A male from Panama and a female from Nicaragua. Very like Z. adustus, from HILIPUS. 4] which it differs in the smoother and less thickened rostrum (¢ and @), the less uneven upper surface, the more closely granulate prothorax, and the sub-bifasciate elytra. 64. Hilipus angulosus, sp. n. (Tab. III. figg. 24; 24a, profile.) Oblong-ovate, opaque, black, the antenne and tarsi obscurely rufescent, the upper surface thickly clothed with minute greyish scales, those on the scutellum whitish ; the elytra each with a “\-shaped streak on the disc about the middle and three marks before the apex (the central one V-shaped) velvety-black, and a common, evanescent, whitish fascia on the apical declivity, the space between this and the dark anterior streak being clothed with brownish scales ; the under surface, rostrum, and legs with whitish piliform scales. Head sulcate between the eyes, which are rather narrowly separated; rostrum very stout, distinctly widening outwards, curved, about as long as the prothorax, rugosely punctured, towards the base obsoletely carinate in the middle and at the sides; antenns inserted near the apex of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax convex, transverse, moderately rounded at the sides, constricted and narrowed in front, strongly bisinuate at the base; the surface uneven, and very sparsely, irregularly, finely granulate. Elytra fully one-half wider than the prothorax, parallel in their anterior half, sinuato-truncate at the base, slightly emarginate at the apex, flattened along the suture, the humeri somewhat angular externally ; coarsely seriate-punctate, the interstices with widely- scattered, irregularly-arranged, smooth granules, each of these bearing a short decumbent seta; the subapical callosities, and the third, fifth, and seventh interstices at about the middle, angularly or acutely raised, these elevations and the black fascia limiting a large flattened space on the apical declivity. Ventral surface very finely punctate, the first suture feebly bisinuate. Length 114, breadth 5 millim. (?¢.) Hab. Payama, Bugaba (Champion). One specimen only of this curious form has been obtained. There is a Brazilian insect very like it at the British Museum labelled with the MS. name ZH. signatus, a term already applied to a different species. The subapical callosities on the elytra are dentiform and very prominent. . 65. Hilipus strigipectus, sp.n. (Tab. II1. figg. 25, ¢; 25a, metasternum.) Oblong-ovate, slightly shining, piceous or rufo-piceous, maculated with black; the upper surface variegated - with a somewhat dense clothing of small ashy, fulvous, and brownish scales, the ashy scales tending to form three streaks or a cruciform patch on the disc of the prothorax and two interrupted fascize on the elytra, the fulvous ones predominating on the head, on the sides of the prothorax, and on the scutellum, the elytra each with a small rounded or oval velvety-black patch on the dise beyond the middle; the under surface thickly clothed with coarse, fulvous or whitish, piliform scales, the legs with long, similarly- coloured hairs, the four hinder tibia with very long and fine hairs on the inner side towards the tip. Head densely punctured, shallowly foveate between the eyes, which are rather widely separated ; rostrum feebly curved, shining, rugosely punctured—in the ¢ stout, widening outwards, about as long ‘as the prothorax, and obsoletely carinate at the base, in the 2 longer, more slender, and smoother at the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax convex, nearly as long as broad, moderately rounded at the sides, constricted and narrowed in front, strongly sinuate at the base; sparsely granulate, the anterior portion densely punctate. Elytra one-half wider than the prothorax, strongly sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, flattened along the suture, and somewhat abruptly declivous at the sides, the humeri rounded and prominent; seriate- punctate and also granulate, the interstices transversely wrinkled, the third slightly raised. Metasternum very finely and closely transversely strigose, deeply sulcate down the middle, glabrous.

Mexico, Cerro de Plumas (£/6ge). Three specimens. Closely allied to H. guadrinodosus, with which it agrees in the transversely strigose metasternum; but smaller and narrower, with more prominent humeri; the elytra less uneven and without a prominence on the third interstice, the velvety-black spot placed further from the apex ; the rostrum not so stout. The strigose surface of the metasternum looks as if it might be used for stridulatory purposes. ‘The dense brush of long hairs on the first and second joints of the anterior tarsi in the male is a very remarkable character. 66. Hilipus punctipectus, sp. n. Extremely like H. strigipectus, but differing as follows:—The prothorax with a rather large patch of fulvous scales on each side at the base, the velvety-black patch on the disc of each elytron a little more elongate, the piliform scales on the under surface not so coarse, longer, and more abundant; the rostrum (¢) stouter and a little longer, densely ragose to the tip, so as to appear dull; the metasternum clothed with piliform scales like the rest of the under surface, closely and simply punctate, shallowly sulcate down the middle; first ventral segment( ¢ ) impressed down the middle from the base to the apex ; first and second joints of the anterior tarsi (¢) without brushes of long hair; the intermediate and hind tibie without additional long hairs on the inner side towards the apex. Length 11, breadth 45 milim. Hab. Mexico, San Andres Tuxtla (Sal/é). One specimen, so like //. strigipectus as to be separable only by the characters mentioned, the general coloration and facies being almost exactly similar. 67. Hilipus bioculatus. (Tab.

It may be recognized by its comparatively broad short form and shining surface, the elytra each with a small, oval, velvety-black spot on the disc beyond the middle, this spot surrounded by a line of ochreous or whitish scales, the rest of the upper surface being sparsely clothed with narrow greyish or brownish scales. The first two ventral segments are convex, and unimpressed in both sexes. : HILIPUS. 43 68. Hilipus cxcus, sp. n. (Tab. III. fig. 27, 2.) Heilipus cecus, Chevyr. in litt. Oblong-ovate, opaque, the granular elevations only shining, black, thickly clothed with brownish piliform scales, with a few whitish ones intermixed, these latter tending to form a sinuous interrupted line on either side of the prothorax, the elytra variegated with blackish scales, and each with a small, conspicuous, oblong or oval, velvety-black patch on the fourth interstice slightly beyond the middle, the scutellum clothed with white or pale ochreous scales; the under surface and legs with scattered, narrow, whitish scales. Head foveate between the eyes, which are rather narrowly separated ; rostrum slightly curved, moderately stout, considerably longer than the prothorax, thickly punctured towards the base; antennw inserted before the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax much broader than long, rounded at the sides, constricted and much narrowed in front, sparsely granulate, the elevations smooth and transverse, without trace of median carina. Elytra one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate- punctate, the interstices with smooth, transverse, granular elevations, and transversely wrinkled towards the base. Metasternum foveolate along the outer margins. Ventral segments 1 and 2 rather convex, 1-4 sparsely and finely, and 5 coarsely, punctate, 1 unimpressed in the male. Length 10-12, breadth 43-53 millim. (¢ Q.) Hab. Mexico, Toxpam (Sallé), Jalapa (Hoge, Trujillo). Sent in plenty from Jalapa. ‘The specimens in the Sallé collection are labelled with the MS. name H. cewcus, Chevr. Allied to H. bioculatus, from which it differs in the opaque and more densely squamose upper surface, and in having the smooth, transverse, granular elevations on the elytra extending to the base, instead of being confined to the apical declivity, those on the prothorax being also more prominent. No definite male-characters are visible beneath. There is a WHilipus from Brazil very like H. cecus in Dr. Sharp’s collection labelled H. fallax, Sch., but this insect has the scales on the upper surface much less elongate, and the elevations on the elytra more transverse. 69. Hilipus unifasciatus, sp.n. (Tab. IV. fig. 1, 2.) Heilipus unifasciatus, Chevr. in litt. Oblong-ovate, shining, black; variegated above with very small widely-scattered patches of whitish or ochreous, rather coarse piliform scales, and also with very minute, loosely-attached, narrow, brownish ones, the larger scales sometimes aggregated so as to form a narrow, irregular, sinuous, postmedian fascia on the elytra and a short median line at the base of the prothorax and a sinuous one on each side of its disc, the scutellum with whitish scales; the under surface very sparsely, and the legs more thickly, clothed with whitish piliform scales. Head closely punctured, foveate between the eyes, which are narrowly separated; rostrum stout, feebly curved in the ¢, nearly as long as the head and prothorax, and closely or rugosely punctured towards the base, in the ? smoother at the tip and a little more elongate, the antennal grooves widely separated at the base beneath; joints 1 and 2 of the funicuius equal in length. Prothorax transverse, rounded at the sides, narrowed and constricted in front and narrowed behind, strongly bisinuate at the base; sparsely granulate at the sides and towards the base, a space on the anterior part of the disc being impressed with intermixed, minute, and rather coarse punc- tures. Elytra one-third wider, and about two and one-half times longer, than the prothorax, sinuate at the base, gradually narrowing from the rounded, somewhat swollen humeri, conjointly rounded at the apex ; deeply seriate-punctate, the punctures becoming finer and more scattered towards the apex, the interstices slightly wrinkled towards the base and in some specimens finely granulate on the apical GG 2 44 RHYNCHOPHORA. declivity. Sides of the metasternum and the apex of the fifth ventral segment coarsely foveolate, ventral segments 1-4 very sparsely, minutely punctate, 1 slightly depressed in the middle in the male. Length 74-11, breadth 33-5 millim. (d @.) Hab. British Honpvras, Rio Sarstoon (Blancaneaux) ; GuaTemaua, Panzos (Conradt, Champion), Chacoj, San Juan, Senahu (Champion); Nicaracua, Chontales (Beit) ; Panama, Bugaba, Volcan de Chiriqui (Champion).—CotomBia (Mus. Brit.). Var. The squamosity of the upper surface a little more abundant; the elytra more rugose towards the base, with the interstices faintly granulate, the punctures usually very coarse on the basal half. (¢ 2.) Hab. Mexico, Sierra de Durango, Amatan, Motzorongo (Blot), Toxpam (Sallé), Misantla (Hége). Of this variable species, which may be known by its shining and very sparsely squamose surface (approaching JI. bioculatus in this respect), we have received a long series of specimens from within our limits, those from the Sallé collection being labelled H. unifasciatus, Chevr. There is an example of it, too, from Colombia, in Dr. Sharp’s collection, ticketed H. indistinctus, Jekel. Very similar forms seem to be generally known under the name of H. clavipes (Fabr.); but I cannot reconcile our insect with Boheman’s description of the Fabrician species, in which he says that it is of the length of Cleonus sulcirostris, and has the elytra four times as long as the thorax, &c. The minute brownish scales are easily abraded, the larger ones only being conspicuous. Compared with H. bioculatus, the present species is relatively narrower. 70. Hilipus cinctipennis, sp. n. Oblong-ovate, subopaque, black, the upper surface clothed with very fine, piliform, fulvous or brownish scales, the elytra each with a rather broad transverse fascia of coarser whitish or ochreous scales on the disc a little beyond the middle; the under surface and legs with scattered, whitish, piliform scales. Head deeply foveate between the eyes, which are somewhat widely separated ; rostrum stout, feebly curved, short, not longer than the prothorax, closely punctured, smoother at the apex and along the middle; joints 1 and 2 of the funiculus equal in length. Prothorax broader than long, moderately rounded at the sides, strongly bisinuate at the base, narrowed and constricted in front ; subgranulate and also punctate at the sides and base, a space on the anterior part of the disc irregularly punctured (the entire surface, when viewed under a strong lens, densely minutely reticulate). Elytra about one-third wider than, and three times the length of, the prothorax, subparallel in their basal half, somewhat compressed at the sides before the middle, strongly sinuate at the base, conjointly rounded at the apex, the humeri rounded and a little swollen; seriate-punctate, the punctures on the apical declivity almost obsolete and replaced by scattered granular elevations, the interstices transversely wrinkled towards the base. Ventral segments 1-4 very sparsely, minutely punctate, 1 flattened or faintly depressed in the middle. Length 9-113, breadth 33-4? millim. (¢.) Hab. Mexico (Sailé); Guatemauta, Panzos (Champion); Nicaragua, Chontales (Janson). A single specimen from each locality (the one from Mexico being immature), evidently males, the rostrum being short and stout in all of them. Very like H. unifasciatus, but less shining, the prothorax and elytra without small scattered HILIPUS. AH patches of whitish scales, the fascia on the elytra broader, more transverse, and more distant from the apex, the punctures on the actual declivity almost obsolete and replaced by scattered granules, the prothorax less rounded at the sides. ‘he tibie- are sharply mucronate in the Mexican example, feebly so in the others. 71. Hilipus crux-alba, sp. n. (Tab. IV. fig. 2, 2.) Oblong-ovate, somewhat shining, black or pitchy-black, variegated above with small scattered patches of coarse, piliform, fulvous scales, and also with very minute brownish ones, the elytra each with a large, irregular, cruciform patch of intermixed coarse, whitish and fulvous scales on the disc beyond the middle ; the pleura with coarse, and the rest of the under surface and the legs with piliform whitish scales. Head closely punctate, deeply foveate between the eyes, the latter rather widely separated; rostrum curved, in the ¢ stout, not longer than the prothorax, and rugosely punctured to the tip, in the 9 more slender, as long as the head and prothorax, and smoother towards the tip, the antennal grooves rapidly descending and somewhat narrowly separated at the base beneath; antenne inserted near the apex of the rostrum in the ¢, much further back in the 9, joints 1 and 2 of the funiculus equal in length. Prothorax convex, transverse, rounded at: the sides, constricted and narrowed in front, strongly pisinuate at the base, broadly and deeply emarginate at the apex (so as to appear to have rather prominent ocular lobes); somewhat closely granulate, the apex closely punctate, and sometimes with a faint, abbreviated, median carina. Elytra one-half broader than, and two and one-half times the length of, the prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded; very coarsely and closely seriate-punctate, the interstices narrow, somewhat raised, transversely wrinkled, and finely granulate. Beneath very sparsely, minutely punctate, the sides of the metasternum and the apex of the first ventral segment foveolate, the first segment unimpressed in both sexes. Length 9-10, breadth 4-43 millim. (¢ 9.) Hab. Mexico, Jalapa, Misantla (Hoge), Temax in North Yucatan (Gaumer). Nine specimens. It is possible that these may prove to be a form of H. tugusti, which is also said to have somewhat prominent ocular lobes to the prothorax; but as Boheman does not mention the granulation of the elytra, &c., our insect must be treated as distinct for the present. The rapidly-descending scrobes, the closer granulation of the upper surface, the large cruciform patch on the disc of each elytron, the more deeply emarginate apex of the prothorax, &c., readily separate H. crux-alba from H. unifasciatus. H. albosignatus, Kirsch, from Bogota, must also be a nearly-allied form. 72. Hilipus scutellaris, sp.n. (Tab. IV. fig. 3.) Oblong-ovate, slightly shining, black, the head, rostrum, legs, and antennz more or less piceous or rufo-piceous, the upper surface variegated with narrow fulvous and blackish scales ; the elytra each with a subtriangular velvety-black or dark brown patch on the disc beyond the middle, this being followed by two or three small pure white spots, and sometimes preceded by a single one, and with several small white spots along the outer margin, there being also one on the mesepimera; the prothorax with a small white spot at the base on each side and one in front of the anterior cox, the scutellum also clothed with white scales ; the under surface and legs very sparsely clothed with narrow whitish scales. Head closely punctured, foveate or sulcate between the eyes, which are somewhat narrowly separated ; rostrum curved, moderately stout, much longer than the prothorax, thickly punctured to the middle; antenn inserted near the middle of the rostrum, joint 2 of the funiculus a little longer than 1. Prothorax convex, broader than long, bisinuate at the base, rounded at the sides, narrowed and constricted in front, sparsely conspicuously granulate, without trace of central ridge. Elytra one-half wider than the prothorax, subparallel at the 46 RHYNCHOPHORA. base, conjointly rounded at the apex, the humeri rounded; seriate-punctate and finely granulate, the interstices transversely wrinkled. Metasternum deeply foveate along the outer edge. Venter convex towards the base, segments 1-4 almost smooth, unimpressed. Length 11-18, breadth 43-5} millim. Hab. Nicaracva (Sallé), Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion). Six examples, probably including both sexes, the males of some of the allied forms (H. bioculatus and H. cecus) also having the first ventral segment unimpressed. ‘The present species is very like H. nigrofasciatus; but is narrower and less robust, the eyes are not contiguous above, the prothorax has two white spots at the base and is more coarsely granulate, the outer edges only of the metasternum are foveolate, &c. 73. Hilipus pulverulentus, sp.n. (Tab. IV. fig. 4.) Oblong-ovate, shining, rufo-piceous, the head, rostrum, and tarsi rufescent; the upper surface (the head excepted) somewhat thickly clothed with tawny scales, the legs and under surface with long piliform scales. Head foveate between the eyes, which are somewhat widely separated ; rostrum moderately stout, curved, one-half longer than the prothorax, closely and finely punctured towards the base; antenne inserted at about the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club longer than the five preceding joints united. Prothorax much broader than long, convex, rounded at the sides, constricted and considerably narrowed in front, strongly bisinuate at the base; the surface, except for a narrow space along the middle behind, finely and rather sparsely granulate, the interspaces densely, minutely punctate. Elytra one-fourth. wider than the prothorax, strongly sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices transversely wrinkled and finely granulate. First ventral segment faintly depressed down the middle behind. Length 124, breadth 5 millim. Hab. Nicaragua, Chontales (Belt). One specimen, probably a female, though the first ventral segment is distinctly impressed in the middle. Chiefly distinguishable by the dense uniform tawny clothing of the prothorax, scutellum, and elytra, the strongly-sinuate base of the latter, and the finely-granulated upper surface. H. pulverulentus is closely allied to the South- American H. pertyi, Schonh. (=rufipes, Boh.), but differs from it in having the squamosity of the elytra uniformly tawny (instead of variegate with black and white), and the elytra themselves less elongate. 74. Hilipus fulvisquamis, sp.n. (Tab. IV. fig. 5, 2.) Oblong-ovate, moderately shining, rufo-piceous, the rostrum and legs sometimes rufescent; the upper surface somewhat thickly clothed with bright fulvous piliform scales, which on the pronotum are concentrated into two broad oblique vitte: (a space down the middle and the flanks being very sparsely squamose); the elytra with a small spot or transverse mark on the disc a little beyond the middle, sometimes extending outward to near the margin, and usually a small spot immediately behind the subapical callosities, black ; the legs and under surface sparsely clothed with whitish and fulvous piliform scales. Head foveate between the eyes, which are somewhat widely separated ; rostrum feebly curved, stout, and about one- fourth longer than the prothorax in the ¢, a little longer and more slender in the 9, rather closely punctured towards the base; antenne inserted a little before the apex of the rostrum in the @, further back in the @, joint 2 of the funiculus longer than 1(¢), or 1 and 2 subequal in length (2 ). HILIPUS. 47 Prothorax broader than long, moderately rounded at the sides, considerably narrowed in front, bisinuate at the base, sparsely granulate. Elytra one-half wider than the prothorax, subparallel towards the base, conjointly rounded at the apex, the humeri rounded; seriate-punctate, the interstices transversely wrinkled and also granulate. Ventral segment 1 in the ¢ shallowly grooved down the middle, and with a dense oblong patch of ochreous and white scales on each side of the depression; in the Q sometimes depressed along the middle behind. Tibise mucronate in the 9, obsoletely so in the ¢, Length 94-12, breadth 33-5 millim. (¢ 2.) Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet, Bugaba (Champion). Eleven specimens. Not unlike H. pulverulentus, but narrower and less robust, the prothorax narrower, less rounded at the sides, and with the fulvous clothing more or less concentrated into two broad converging vittee on the disc; the elytra less sinuate at the base, and with a transverse black mark or fascia beyond the middle (sometimes reduced to a small spot), and usually a spot beyond it. 75. Hilipus hyperoides, sp. n. Oblong-ovate, shining, black, the legs and antenne in part piceous or rufo-piceous; the upper surface some- what thickly clothed with fulvous scales, with some whitish ones intermixed, the latter concentrated into a small patch on the disc of each elytron beyond the middle and also covering the scutellum; the under surface and legs with scattercd, whitish, piliform scales. Head closely punctured, foveate between the eyes, which are widely separated; rostrum moderately stout, curved—in the g about as long as the prothorax and closely punctured throughout, in the Q a little longer, more slender, and smoother at the tip; joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the sides, abruptly constricted and narrowed in front, strongly bisinuate at the base ; closely granulate at the sides, sparsely and transversely so on the dise. Elytra one-half wider than, and three times as long as, the prothorax, sinuate at the base, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded and somewhat swollen; deeply seriate-punctate, the interstices broad, granulate on the apical declivity, the outer ones granulate and transversely rugose. Metasternum and ventral segments 1-4 very sparsely, minutely punctate, the first segment unimpressed in both sexes, the metasternum short, foveolate along the outer margin. Legs comparatively short, the tibie feebly mucronate. Length 8, breadth 3? millim. (¢ 2.) Hab. Mexico, Santecomapan in Oaxaca (Sallé); British Honpuras (Blancaneauz). - Two rather worn specimens. ‘This species resembles H. dioculatus in general shape, except that it is smaller and less convex, and has relatively shorter elytra. The amount of white squamosity is variable, it being more abundant in the Mexican insect than in the one from Honduras. 76. Hilipus sulcifer, sp. n. (Tab. IV. figg. 6, 6; 6a, terminal ventral segments, 9 .) Elongate-ovate, black or piceous, the antenne and legs sometimes partly rufescent; mottled above with a somewhat dense clothing of fulvous and whitish scales, the latter often aggregated so as to form an oblique stripe on the outer part of the elytra below the base and a common apical patch, the elytra with a spot on the outer part of the disc beyond the middle (in some specimens large and sharply defined, in others indistinct), an oblong one close to the suture at the apex, and sometimes several others on the apical half, black; the under surface and legs thickly clothed with whitish and fulvous scales. Head rugosely punctured and not or feebly foveate between the eyes, which are rather narrowly separated; rostrum in the ¢ stout, feebly curved, as long as or longer than the prothorax, rugosely punctured and obsoletely quadricarinate towards the base, smoother at the tip, that of the 2 a little longer and smoother, the 48 RHYNCHOPHORA. antennal grooves in both sexes rapidly descending and closed behind; antenne inserted slightly before the middle of the rostrum, joint 2 of the funiculus distinctly shorter than 1. Prothorax transverse, more or less rounded at the sides, narrowed and constricted in front; coarsely or finely granulate, and with a short, conspicuous, median carina at the middle. Elytra moderately long, one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex, flattened on the disc, with the third interstice often more or less costate, the humeri rounded; seriate-punctate, the interstices granulate and usually transversely rugose. Metasternum long, foveolate at the sides. Ventral segments somewhat closely, finely punctate, the fifth with a sharply-defined, deep, narrow sulcus down the middle in both sexes, the first furnished with two backwardly-projecting matted tufts of fulvous piliform scales at the middle behind in the ¢. Length 63-9, breadth 24-34 millim. Hab. Mexico (Sallé), Ventanas in Durango (Forrer), Jalapa, Cordova (Hége); GuatTeMaLA, Chacoj, Teleman, Mirandilla, Cerro Zunil (Champion); Nicaragua, Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion). The twenty-one specimens referred to this species agree in baving the fifth ventral segment sulcate down the middle and the second joint of the funiculus shorter than the first; but there is great variation amongst them in the sculpture and coloration of the prothorax and elytra (the smoothest specimens having the prothorax straighter at the base and less rounded at the sides), and in the relative length and sculpture of the rostrum. The extreme forms were obtained with the more typical ones at several localities, and there can be little doubt that they all belong to one variable species. H. sulcifer resembles H. trinotatus in general facies, except that it is much smaller. 77. Hilipus penicillatus, sp. n. (Tab. IV. figg. 7, 2; 7a, part of under surface, 3.) _Oblong-ovate, black or piceous, the legs and antennze sometimes partly rufescent; thickly clothed with small, rounded, greyish-brown scales, the prothorax with intermixed piliform scales, the elytra more or less mottled with ochreous or whitish towards the apex, and each with a transverse or A -shaped velvety-black mark on the disc beyond the middle, and a short black streak or triangular mark near the suture before the apex, the scales on the scutellum whitish ; the under surface and legs thickly clothed with ochreous or whitish scales, those on the pleura mostly rounded, the others piliform. Head rugosely punctate, shallowly foveate between the eyes, the latter somewhat narrowly separated ; rostrum in the ¢ very stout, moderately curved, not longer than the prothorax, rugosely punctured and tri- or quadricarinate at the base, in the 2 a little longer and smoother, the antennal grooves descending to the lower angle of the eye and closed behind ; antenne inserted near the apex of the rostrumin the ¢, further back in the @, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, convex, moderately rounded at the sides, constricted and narrowed in front, feebly bisinuate at the base ; rather coarsely granulate, without trace of median carina. Elytra one-half wider than, and three times the length of, the prothorax, parallel. in their basal half, subtruncate at the base, conjointly rounded at the apex, the humeri rounded and rather prominent ; seriate-punctate, the interstices transversely wrinkled, the third interruptedly costate, and all of them with smooth scattered granular elevations, each bearing a long decumbent seta. Metasternum and venter very minutely punctate, with scattered coarse punctures, these being deeply impressed on the second ventral segment; first ventral segment broadly produced in the middle behind in both sexes, and with two matted tufts of ochreous piliform scales in the middle at the apex in the ¢. Length 5-74, breadth 24-31 millim. (¢ 9.) . Hab. GuateMaLa, San Juan in Vera Paz (Champion); Panama, Bugaba, Volcan de Chiriqui (Champion). HILIPUS. 49 Fourteen specimens, one only being from Guatemala. This species, except that it is very much smaller, has the same general shape and coloration as H. angulosus, in which the apex of the first ventral segment is slightly produced in the centre behind. In the setigerous elytra it resembles H. asperatus, &c. The following species is unknown to me. It may belong to Hilipinus. 78. Hilipus tugusti. Heilipus tugusti, Boh. in Schénh. Gen. Cure. vii. 2, p. 45°, Hab. Mexico (coll. Chevrolat'). I am unable to certainly identify this species amongst our material, and the type of it cannot be found in the Chevrolat collection at Stockholm. It is described as nigro- piceous in colour, variegated above with yellowish piliform scales, the elytra with a large, transverse, fulvous patch far beyond the middle. The prothorax broader than long, rounded at the sides, closely granulate throughout, and with rather prominent ocular lobes. The elytra one-half broader than, and nearly three times as long as, the prothorax, with the sides straight to beyond the middle, and then convergent to the apex, which is rounded; rather deeply and closely seriate-punctate, with the interstices narrow, subconvex, and transversely rugose. | In my remarks under J. belti (antea, p. 15) mention is made of a nearly allied form with a peculiarly shaped prothorax: a second specimen of this insect has since come to hand, and a description of it is therefore appended :— 14 (a). Hilipus compressicollis, sp.n. (Tab. IV. fig. 8, ¢.) Oblong-ovate, shining, black, a broad space extending across the entire disc of the prothorax and the incrassate portion of the femora rufous; the elytra with numerous, irregular, whitish, transverse spots and markings, the latter tending to form two common angulated fascie, one before, the other beyond the middle. Head foveate between the eyes; rostrum stout, curved, about as long as the prothorax, sparsely punctate towards the base. Prothorax broader than long, rounded at the sides, sinuously narrowed behind and constricted and much narrowed in front, the disc broadly and obliquely depressed on each side before the middle (the depression extending inward from the lateral constriction), the base very strongly bisinuate, the surface sparsely, irregularly punctate. lytra one-half wider than the prothorax, subparallel towards the base, seriate-punctate, the interstices faintly transversely wrinkled. Venter with a broad depression extending down the middle of segments 1 and 2. Length 16-17, breadth 64-64 millim. (¢.) Hab.

Lond. 1881, p. 96. Parameleus, Faust, Stett. ent. Zeit. 1892, p. 33. In the species referred to this genus the anterior opening of the scrobes is visible from above, the scrobes. themselves extending forwards at the base of the rostrum beneath, so as to receive the first joint of the funiculus, being, in fact, W-shaped in both sexes. The antenne are inserted near the apex of the rostrum in both male and female. The tibie are more or less distinctly mucronate at the inner apical angle (at least in the females), the claw arising from about the middle of the apical margin in the female, and from at or near the inner angle in the male. Arniticus includes several South-American forms described by Pascoe and Faust, as well as Hilipus lituratus and H. perturbatus, Boh., H. arrogans, Pasc., and others. Two are now added from within our limits. 1. Arniticus cingulatus, sp. n. (Tab. IV. figg. 9, ¢; 9a, profile of head and rostrum; 9 4, front tibia, ¢ ; 10, front tibia, 2 .) Oblong-ovate, black or piceous, the upper surface variegated with ochreous, whitish, and black scales, the whitish scales forming two narrow, sinuous, oblique vitte on the prothorax, a triangular spot on the scutellum, and an irregular humeral patch and a broad curved, transverse, ante-apical fascia on the elytra; the under surface and legs with scattered ochreous or whitish scales. Head rugose, feebly foveate between the eyes, which are rather narrowly separated ; rostrum about one-third longer than the prothorax, stout, moderately curved, rugose almost to the tip; joint 2 of the funiculus twice as long as 1. Prothorax transverse, rounded at the sides anteriorly, slightly constricted before the apex and subparallel behind ; rather sparsely granulate, and with a sharply-defined incomplete median carina. Llytra about one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex, the sutural angles somewhat pointed, the humeri rounded externally and truncate in front; deeply seriate- punctate, the interstices more or less convex, each with a somewhat closely placed series of setigerous granular elevations. Venter broadly depressed down the middle towards the base in the gd. Tibi with the claw arising from the inner angle in the ¢, mucronate in the 2. Length 10-134, breadth 4-6 millim. (¢ 2.) Hab. Guatemata, El Tumbador, Cerro Zunil, San Isidro, Panajachel, Mirandilla (Champion) ; Panama, Volcan de Chiriqui, Caldera (Champion). Found in abundance at Cerro Zunil and sparingly elsewhere, all the localities being on the Pacific slope. The coloration is somewhat variable, four of the specimens (from Panajachel, Mirandilla, San Isidro, and Chiriqui respectively) having the light markings pale ochreous, instead of white. A. cingulatus is extremely like the Colombian A. lituratus (Boh.), but that insect has a much broader prothorax, and the elytral setee shorter and less conspicuous. | * Erratum:—lIn the description of H. belti (anted, p. 15)—For “ side-pieces of the metasternum rufous,” read “ metasternum, the side-pieces excepted, rufous.” ARNITICUS.—HILIPINUS. 51 2. Arniticus setiger, sp.n. (Tab. IV. fig. 11, 2.) Oblong-ovate, nigro-piceous, the upper surface variegated with ochreous, whitish, and black scales, the whitish scales forming a triangular spot on the scutellum, a small spot at the base of the fifth interstice of the elytra, and a narrow, curved, transverse, more or less distinct fascia on the disc of the latter beyond the middle ; the under surface and legs clothed with ochreous scales. Head rugose, feebly foveate between the eyes, which are rather narrowly separated; rostrum stout, moderately curved, about one-third longer than the prothorax, longitudinally rugose, smoother at the tip in the ; joint 2 of the funiculus nearly twice as long as 1. Prothorax transverse, rounded at the sides, much narrowed anteriorly and slightly constricted before the apex ; sparsely granulate and with an abbreviated median carina. Elytra about one-half wider than the prothorax, subparallel to near the middle, conjointly rounded at the apex, the sutural angles somewhat pointed, the humeri rounded ; deeply seriate-punctate, the interstices somewhat convex, each with a widely scattered series of granular elevations, these being furnished posteriorly with a long, semierect, stout, pallid seta.

Nicaracua, Chontales (Belt). _ Seven examples of the typical form, and two of the variety, which should perhaps be treated as a separate species. Very like A. cingulatus, but less elongate, the prothorax more rounded at the sides and without distinct vitte, the elytra with fewer granular elevations in the interstitial series and these bearing longer and stouter sete. From A. perturbatus (Boh.) it differs in having a more distinctly carinate prothorax and longer elytral sete. HILIPINUS, gen. nov. Scrobes partly visible from above, open and extending forward on the inner side beneath, in the ¢ reaching to at least the middle of the rostrum, and receiving the whole or part of the funiculus, and sometimes the club also, in the @ receiving the basal joint only of the funiculus. Tibial claw arising from: the inner apical angle of the tibia in the d, and from near the middle of the apical margin in the Q, the inner apical angle mucronate in the 2. Tibie usually more or less sulcate on their outer edge, and the rostrum also on either side above. The other characters as in Hilipus. This group of species, the characters of which were in part noticed by Lacordaire (Gen.

The antenne are inserted in both sexes near the apex of the rostrum. The humeri in many of the species are angular in front. The rostrum in the male has two prominences at the base beneath, these sometimes forming sharp teeth.

Elongate, broad, robust, black, variegated above with minute fulvous scales, with still smaller scales intermixed ; the under surface and legs also clothed with fulvous scales, those on the pleura and the sides of the venter coarser than the rest. Head densely, rugulosely punctured, not foveate between the eyes, which are somewhat widely separated; rostrum very stout, broad, feebly curved, a little longer than the prothorax, rugulosely punctured to the tip and indefinitely tricarinate, laterally sulcate, the scrobes in great part visible from above and forming deep sinuous furrows beneath for the reception of the funiculus and club ; joint 2 of the funiculus considerably longer than 1. Prothorax transverse, feebly bisinuate at the base and deeply emarginate at the apex, the sides almost straight behind and arcuate and converging anteriorly, strongly constricted in front; the surface densely, very minutely punctate and also very finely granulate, with an interrupted median carina. Elytra one-fifth wider than, and three and one-half times as long as, the prothorax, moderately convex to the middle and flattened on the disc thence to the apex, the sides subparallel to beyond the basal half, the apices a little produced at the sutural angle, the humeri rounded externally and truncate in front; shallowly and rather finely seriate-punctate, the interstices broad, densely rugulose, and minutely granulate. Venter closely, finely punctate, the first and second segments very broadly depressed down the middle. Tibiz shallowly sulcate. Length 214, breadth 9 millim. (<¢.) Hab. Guatemata, Chacoj in the Polochic Valley (Champion). One specimen. This species, which is more elongate in form than the allied H. ascius and H. biguttatus, is remarkable from the fact of having the rostrum sufficiently sulcate beneath to receive the entire antenna in repose, the sulci curving outwards towards the apex of the rostrum and widely separated at its base. H. corruptor (Boh.), from Brazil, is very like H. ingens, but the rostrum in the male of the latter 1 is not nearly so stout, and has the funicular grooves parallel. HILIPINUS. O93 2. Hilipinus biguttatus, sp.n. (Tab. IV. fig. 18, ¢.)

Head rugulosely punctured, not foveate between the eyes, which are widely separated ; rostrum very stout, broad, feebly curved, slightly longer than the prothorax, rugosely punctured and tricarinate, smoother at the tip, sulcate laterally, the scrobes in great part visible from above and forming broad deep furrows beneath for the reception of the funiculus, these becoming divergent towards the apex; joint 2 of the funiculus twice as long as 1. Prothorax transverse, gradually and arcuately narrowing from a little before the base to the apex, constricted in front, the apex broadly and deeply emarginate, the base feebly bisinuate ; closely and finely granulate, with indications of an abbreviated median carina. Elytra rather convex, about one-fifth wider than, and three times the length of, the prothorax, subparallel in their basal half, the apices mucronate, the humeri rounded externally and truncate in front; seriate-punctate, the interstices broad, transversely rugulose, and finely granulate, Ventral segments finely, rather sparsely punctate, the first broadly depressed in the middle. Length 18, breadth 8 millim. (¢.) Hab. Panama, Chiriqui (coll. Godman & Salvin). One specimen. A close ally of the Brazilian H/. ascius (Germ.), differing from that species in its broader form, the presence of a very large, lateral, brownish-black, velvety patch on each elytron, and the broader and deeper sulci on the underside of the rostrum in the male. 3. Hilipinus laticollis, sp.n. (Tab. IV. fig. 14, 2.) Oblong, robust, slightly shining, black or piceous; thickly clothed with minute scales, which are mostly fulvous in colour, the elytra with a common, indeterminate, transverse, blackish-brown fascia at about the middle followed by a whitish one, and also with a few scattered whitish scales, the scutellum clothed with whitish scales; the under surface and legs with fulvous piliform scales. Head densely rugose, not foveate, the eyes rather widely separated; rostrum (3) broad, very stout, a little longer than the prothorax, longitudinally rugose and also carinate, laterally suleate, the antennal grooves in great part visible from above, (@) a little longer, narrower, and much smoother towards the tip; joint 2 of the funiculus nearly twice as long as 1. Prothorax transverse, broad, deeply emarginate at the apex, feebly pisinuate at the base, the sides rounded anteriorly, almost straight behind, and constricted in front ; closely and very finely granulate, with an abbreviated median carina. Elytra about one-fifth wider than, and three times the length of, the prothorax, moderately convex, subparallel in their basal half, conjointly rounded and considerably produced at the apex, with the sutural angle slightly dentiform, the humeri - rounded externally and truncate in front; closely seriate-punctate, the interstices somewhat convex, trans- versely rugulose, and very finely granulate. Venter sparsely punctate, the first and second segments very broadly depressed down the middle in the male. . Length 14-154, breadth 54-63 millim. (¢ 2.) Hab. Ntcaraeua, Chontales (Belt). Two males and two females. Smaller and less elongate than H. ingens, and more oblong than Hi. biguttatus and H. ascius, and differing from all three in the maculation of the elytra, these having an irregular, common, dark fascia at about the middle followed by a whitish one. The prothorax is very broad, as in H. ingens, but less 54 RHYNCHOPHORA. abruptly constricted in front. H. maculosus (Boh.), from Brazil, is also an allied, broader form. 4, Hilipinus alternatus, sp. n. Oblong-ovate, slightly shining, black; the head and prothorax variegated with small fulvous scales, the scutellum clothed with whitish ones; the elytra thickly clothed with fulvous scales, and each with a subquadrate brownish-black spot about the middle of the disc and a smaller subtriangular one near the apex, the stria with alternate brownish-black and whitish spots, the base with a fulvous spot near the shoulder; the under surface and legs clothed with fulvous and whitish scales. Head densely, rugosely punctate, not foveate, the eyes rather widely separated ; rostrum stout, a little longer than the prothorax, feebly curved, sparsely punctate, much smoother towards the tip, deeply sulcate laterally ; joint 2 of the funiculus nearly twice as long as 1. Prothorax transverse, deeply emarginate at the apex, feebly bisinuate at the base, the sides moderately rounded, constricted and much narrowed in front; closely granulate and with an interrupted median carina. Elytra about one-fourth wider than, and three times the length of, the prothorax, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded externally and truncate in front; seriate-punctate, the interstices finely granulate. Venter sparsely, minutely punctate, with coarser punctures intermixed, the first segment depressed down the middle behind. Length 114, breadth 51 millim. (Q.) Hab. Guatemata, Torola (Champion). One specimen, from the “tierra caliente” of the Pacific slope, evidently a female (to judge from the form of the rostrum), though it has a depression on the first ventral segment. This species isa close ally of H. laticollis, but is much smaller, and has less elongate and very differently marked elytra, each of the strie being maculated with small whitish spots alternating with oblong brownish-black ones, there being also a conspicuous subquadrate blackish spot on the middle of the disc. From similarly- coloured varieties of H. punctatoscabratus the broader form and: more robust build, and: the less rugose elytral interstices, sufficiently distinguish it. 5.

Dr. Aurivillius has been kind enough to lend us the type (¢) of this very variable species, which is not uncommon in Mexico and Guatemala. The elytra are elongate, not much wider than the prothorax, subparallel to the middle and then gradually . narrowed to the apex, which is broadly produced and often dentiform at the sutural * The type is labelled as from “Toulepec,” as stated by Boheman, but this is probably a mistake for *“« Tultepec.” HILIPINUS. — 59 angle. The rostrum is stout, rugose, and more or less carinate in the male, smoother and more slender in the female. The upper surface is more or less variegated with fulvous, whitish or greyish, and brown scales, and there is always a line of pallid scales on each side of the base of the prothorax, a similarly-coloured patch on the scutellum, and another at the base of the elytra near the shoulder, each elytron often having a large irregular black patch (particularly noticeable in immature specimens, but not visible in the type) on the middle of the disc: specimens thus marked are labelled H. biplagiatus, Chevr., in the Sallé collection. The males have a broad depression down the middle of the first or first and second ventral segments. In some specimens the tibiz are faintly sulcate. ‘The species varies greatly in size, from 7-12 millim. in length and 3-5 millim. in breadth. A female of large size from Purula, Guatemala, has the elytra very much broader than the prothorax, with a sharply defined black patch on the disc of each, and the sutural angles produced into a long tooth; it may belong to a different species. A pair from Capetillo are very small and narrow, and these also may have to be separated. 6. Hilipinus mucronatus, sp. n. Oblong-ovate, moderately broad, black, the femora and tibie in part obscurely rufescent ; somewhat thickly clothed with minute fuscous scales, the prothorax with a very small ochreous spot at the base on each side, the elytra with a large rounded velvety-black patch on the disc beyond the middle, followed by two or three small ochreous spots, and aiso with a few other scattered similar spots ; the legs and under surface with scattered, minute, fulvous, piliform scales. Head rugosely punctate, faintly foveate between the eyes ; rostrum moderately stout, feebly curved, much longer than the prothorax, sulcate laterally, closely, finely punctate, the punctuation becoming rugose towards the base. Prothorax strongly transverse, rounded at the sides, and narrowing from a little before the base to the apex, constricted in front, the base almost straight; the surface closely and somewhat coarsely granulate, with an abbreviated median carina. Elytra about one-half wider, and three and one-third times longer, than the prothorax, sub- parallel in their basal half, the apices broadly produced and conjointly rounded, each furnished with a rather long blunt tooth near the sutural angle, the humeri rounded ; seriate-punctate, the interstices. densely rugulose and granulate throughout. Legs elongate. First ventral segment depressed in the middle. Length 134, breadth 6 milim. (@.-) Hab. Mexico, Colonia (Lohr). One specimen. Nearly allied to H. punctatoscabratus, but larger and with a much longer rostrum than in the female of that species ; the elytra separately mucronate at the apex, and with a large, rounded, velvety-black patch on the dise followed by two or three small ochreous spots. 7. Hilipinus scabiosus, sp. n. (Tab. IV. fig. 16, ¢ .) Oblong-ovate, broad, moderately shining, black, the antenna piceous ; the base of the rostrum, the prethorax, scutellum, and elytra clothed with scattered ochreous scales, which tend to form longitudinal streaks on the disc of the latter towards the apex, where they are intermixed with some white ones, the rest of the upper surface clothed with minute fuscous scales ; the legs and under surface thickly, and the middle of the metasternum and the venter sparsely, clothed with ochreous scales. Head rugosely punctured, not 56 RHYNCHOPHORA. foveate between the eyes, which are rather narrowly separated; rostrum stout, feebly curved, rugosely punctured and tricarinate towards the base, almost smooth at the tip, sulcate laterally ; joint 2 of the funiculus nearly twice as long as 1. Prothorax transverse, much narrowed in front and slightly so behind, the sides rounded ; coarsely and closely granulate throughout, with an incomplete median carina. Elytra about one-third wider than the prothorax, comparatively short, subparallel in their basal half, conjointly rounded at the apex, the humeri rounded externally and truncate in front; very coarsely seriate-punctate, the interstices rugose and also granulate. Ventral surface coarsely, sparsely punctate. Legs short and stout, the tibie feebly mucronate. Length 11, breadth 5 millim. (@.) Hab. Panama, Bugaba (Champion). One specimen. Recognizable by its short broad form, peculiar coloration, closely granulate prothorax, and densely squamose legs. 8. Hilipinus fusiformis, sp. n. Subfusiform, fmoderately shining, piceous, the head, rostrum, and legs more or less rufescent ; the upper surface (? abraded) with a few scattered ochreous scales, which are aggregated into an oblique line on each side of the prothorax and two minute spots on the outer part of the disc of each elytron (one at one- third from the base, and the other at one-third from the apex); the under surface with scattered whitish and ochreous scales, the ventral surface and legs with whitish piliform scales. Head densely punctate, shallowly impressed between the eyes, which are somewhat widely separated ; rostrum (¢) broad and stout, curved towards the tip, slightly longer than the prothorax, densely, rugosely punctate from the base to the apex, conspicuously carinate down the middle, and sulcate at the sides, the grooves beneath separated at the base by two flattened dentiform prominences ; joints 1 and 2 of the funiculus equal in length. Prothorax transverse, subconical, closely granulate, the elevations here and there obliquely confluent on the disc, and with an abbreviated median carina. Elytra convex, rather more than three times the length of, and about one-third wider than, the prothorax, considerably produced at the apex, gradually narrowing from the base, the humeri truncate in front and rounded externally, the subapical callosities not prominent ; coarsely and closely seriate-punctate, the interstices smooth and narrow, and on the apical declivity finely granulate. Ventral segments ( 3) 1-5 sparsely, minutely punctate, 1 and 2 with a broad depression down the middle, and 5 depressed on each side. ‘Tibie deeply sulcate on their outer edge. Length 104, breadth 44 millim. (¢.) Hab. Guaremaa, Purula in Vera Paz (Champion). One specimen. In the sulcate tibie and the grooving of the underside of: the rostrum this species agrees with H. sulcirostris and H. sulcicrus, from which it differs in the conical prothorax, the shorter second joint of the funiculus, and the obtuse humeri, the elytra themselves being more convex and gradually narrowing from the base. Viewed in profile, the rostrum is sinuous on its lower edge, this being due to the funicular grooves extending outwards towards the apex. 9. Hilipinus quadrimaculatus, sp.n. (Tab. IV. fig. 17, ¢.) Oblong-ovate, slightly shining, piceous or rufous; the prothorax with an oblique vitta on each side, and the elytra with a rounded or transverse patch at the sides below the shoulders and a rather broad transverse fascia on the disc some distance before the apex, whitish or pale ochreous; the rest of the upper surface clothed with minute scattered ochreous scales; the under surface and legs with scattered narrow white scales, the cilia at the outer apical angles of the four hinder tibiee blackish. Head densely punctured, without distinct fovea between the eyes, which are somewhat widely separated; rostrum a little longer HILIPINUS. 57 than the prothorax, curved, very stout, rugosely punctured except at the tip, sulcate laterally, the antennal grooves in the ¢ extending sinuously forwards beneath ; joint 1 of the funiculus slightly shorter than 2. Prothorax broader than long, rounded at the sides, considerably narrowed in front and slightly so behind ; granulate, and sometimes with an abbreviated median carina, Elytra moderately long, a little flattened on the disc, subparallel at the base, about one-third wider than the prothorax, the humeri rounded externally and subangular in front, the apices somewhat produced and with the sutural angle pointed ; yery coarsely seriate-punctate, the interstices narrow and more or less granulate. Tibie more or less sulcate along their outer edge. First ventral segment sulcate down the middle in the male. Length 9-134, breadth 33-5} millim. (¢ 9.) Hab. Guatremata, El Tumbador and Cerro Zunil, 4000 to 5000 feet (Champion). Found in plenty on the Pacific slope. A close ally of H. integellus (Boh.), but with very different and much more definite whitish markings, these consisting of two sharply- limited spots or fascie on each elytron and a submarginal vitta on either side of the prothorax. . 10. Hilipinus humeralis, sp.n. (Tab. IV. fig. 18, ¢ .) Oblong-ovate, subopaque, piceous or rufo-piceous ; the prothorax with an oblique vitta on each side, and the elytra with a small spot at the shoulder and a large triangular one below it (the two often coalescent and forming a short curved stripe), as well as a broad transverse fascia on the disc some distance before the apex, whitish or pale ochreous ; the rest of the upper surface clothed with minute scattered ochreous scales ; the under surface and legs with scattered, narrow, white scales, the cilia at the apex of the four hinder tibia ochreous. Head closely punctured, not or obsoletely foveate between the eyes, which are somewhat widely separated ; rostrum about one-third longer than the prothorax, curved, very stout, rugosely punctured, except at the tip, suleate laterally; joint 1 of the funiculus slightly shorter than 2. Prothorax much broader than long, rounded at the sides, narrowed and constricted in front and slightly narrowed behind; granulate, and with a smooth median carina. Elytra moderately long, subparallel at the base, about one-third wider than the prothorax, the humeri rounded externally and subangular in front, the apices somewhat produced and with the sutural angle pointed; very coarsely seriate-punctate, the interstices granulate. First ventral segment sulcate down the middle in the male. Tibis obsoletely sulcate on their outer edge. Length 84-114, breadth 33-5 millim. (¢ 2.) Hab. Guatemata, Cerro Zunil, Purula (Champion). Found in numbers at Cerro Zunil with H. quadrimaculatus, of which at first sight it would appear to be nothing more than a varietal form; apart, however, from the additional humeral spot, which is often confluent with the second one, the prothorax is more transverse, and the subapical fascia on the elytra is much broader, forming a large transverse-oval patch on the middle of the disc. 11.

The prothorax is transverse, rounded at the sides, constricted in front, granulate, with a median carina and two irregular, narrow, sinuous, evanescent, ochreous vitte. The elytra are considerably produced at the apex, coarsely seriate-punctate, with the interstices granulate; the markings are sordid-ochreous in colour, and chiefly consist of a large irregular patch on the outer part of the disc before the middle, from which a branch extends forward to the base, a large angulated or cruciform patch on the disc before the apex, and, sometimes, an apical spot. The first ventral segment is deeply depressed down the middle in the male, and the fifth very coarsely punctured. ‘The head is rugosely punctured, not foveate between the eyes, which are rather narrowly separated. The rostrum in the male is about as long as the prothorax, very stout, densely, rugosely punctured, and towards the base carinate and laterally sulcate, the antennal grooves extending far forward along the middle beneath, and forming deep sulci for the reception of the funiculus. 12. Hilipinus sulcicrus, sp.n. (Tab. IV. fig. 20, ¢.) Oblong-ovate, slightly shining; piceous or rufo-piceous, the prothorax with a broad curved vitta on each side, the elytra with a very broad, irregular, sinuous, more or less interrupted, band extending from just within the humeri to the suture a little before the apex, and the head with a few scales between the eyes, white or whitish ; the rest of the upper surface with minute ochreous scales, the under surface and legs with narrow white scales, Head closely punctured, not or obsoletely foveate between the eyes, which are rather narrowly separated; rostrum very stout, curved, a little longer than the prothorax, rugosely punctured almost to the tip, carinate along the middle and shallowly sulcate at the sides ; joint 1 of the funiculus slightly shorter than 2. Prothorax strongly transverse, rounded at the sides, narrowed and constricted in front, and slightly narrowed behind; closely granulate, and with an incomplete median carina. Elytra rather short, about one-fourth wider than the prothorax, subparallel below the base, the humeri rounded externally and angular in front, the apices conjointly rounded ; coarsely seriate-punctate, the interstices granulate. Ventral segments 1—4 almost smooth, 5 coarsely punctured, 1 depressed down the middle behind in the male. Tibiz sulcate on their outer edge. Length 74-9, breadth 3? millim. (d¢ 2.) Hab. Panama, Bugaba (Champion). Three specimens. Very like ZH. integellus, but easily distinguishable therefrom by the broad white prothoracic vitte (the space occupied by these being free from granules), which are continued as an irregular more or Jess interrupted band down the elytra to the suture before the apex, the latter also less produced. The general coloration is very like that of Hilipus cruciatus and its allies. 13. Hilipinus sulcirostris, sp.n. (Tab. IV. fig. 21, 2.) Oblong-ovate, subopaque, nigro-piceous; the prothorax with a sinuous, oblique, pure white vitta on each side, which becomes very narrow in front; the elytra with an irregular curved stripe on the outer part of the disc extending down the basal third, and an interrupted cruciform patch on the disc some distance before the apex, also white ; the rest of the upper surface clothed with minute ochreous scales, which on the elytra are intermixed with fuscous ones, so as to form small spots; the under surface and legs with narrow white scales. Head densely, rugosely punctured, not foveate between the eyes, which are rather HILIPINUS. 59 narrowly separated; rostrum exceedingly stout, curved, a little longer than the prothorax, densely, rugosely punctured almost to the tip, obsoletely carinate, sulcate laterally, the antennal grooves extending far forward along the middle beneath, forming broad, deep, sinuous sulci; joint 1 of the funiculus slightly shorter than 2. Prothorax strongly transverse, rounded at the sides, much narrowed in front and slightly so behind ; granulate, and with an incomplete median carina. Elytra about one-third wider than the prothorax, subparallel below the base, the humeri rounded externally and subangular in front, the apices conjointly rounded; coarsely seriate-punctate, the interstices granulate. Ventral segment 1 sulcate down the middle. Tibiz sulcate on their outer edge. Length 10, breadth 43 millim. (¢.) Hab. Guatemaa (Conradt). One specimen. Allied to H. integellus and H. sulcicrus, but with a still stouter and more rugose rostrum, which is obsoletely carinate above and has longer, broader, and deeper grooves beneath for the reception of the funiculus of the antenne. The prothoracic and elytral markings resemble those of H. integellus, except that they are pure white, and there is no trace of an apical spot; the prothorax, too, is more transverse than in that species. 14. Hilipinus dentirostris, sp.n. (Tab. IV. figg. 22, ¢; 224, profile of head and rostrum.) Oblong-ovate, slightly shining, rufo-piceous, the legs rufescent, with joints 1-3 of the tarsi blackish ; the prothorax with a very small spot on each side at the base near the hind angles, the elytra with a small spot just within the humeri, about five others in an oblique series below this, and a somewhat cruciform mark on the disc towards the apex, white, the rest of the upper surface clothed with minute greyish scales; the under surface and legs with narrow whitish scales. Head rugulosely punctured, the eyes somewhat widely separated ; rostrum very stout, curved, a little longer than the prothorax, rugose almost to the tip, finely carinate down the middle, the antennal grooves extending far forward along the centre beneath and separated at the base by two dentiform prominences ; joint 1 of the funiculus slightly shorter than 2. Prothorax much broader than long, moderately rounded at the sides, constricted before the apex, much narrowed anteriorly and slightly so at the base; finely granulate and with indications of a raised line down the middle. Elytra moderately long, narrowing almost from the shoulders, barely one- fourth wider than the prothorax, sinuate at the base, the humeri angular in front and rounded externally, the apices somewhat produced and conjointly rounded; rather coarsely seriate-punctate, the interstices transversely rugose and granulate. Venter deeply depressed along the middle. Tibi obsoletely sulcate on their outer edge. Length 11, breadth 43 millim. (¢.) Hab. Nicaracua, Chontales (Belt). One specimen. Allied to H. integellus and H. sulcirostris, but with the white markings of the upper surface reduced to small spots, the rostrum armed with two dentiform prominences at the base beneath, the prothorax finely granulate. The grooves on the underside of the rostrum are broad, becoming evanescent beyond the middle. 15. Hilipinus curvirostris, sp. n. Elongate-ovate, narrow, shining, piceous, the antennal scape and the legs in part rufescent; above and beneath clothed with scattered, coarse, oblong, ochreous and whitish scales; the legs with whitish piliform scales. II 2 60 RITYNCHOPHORA. Head densely punctate, foveate between the eyes, which are somewhat widely separated; rostrum stout, strongly curved, about as long as the head and prothorax, for two-thirds of its length densely rugosely punctate, and also carinate and laterally sulcate, the apical third minutely punctate and more shining, the antennal grooves extending shallowly forwards along the middle beneath ; joint 2 of the funiculus much longer than 1. Prothorax strongly transverse, convex, rounded at the sides, abruptly constricted and much narrowed in front, moderately bisinuate at the base; closely and rather coarsely granulate, carinate along the middle towards the apex. Elytra convex, a little wider than, and three times as long as, the prothorax, subparallel in their basal half, the base subtruncate, the humeri obtuse, the apices considerably produced and conjointly rounded, the subapical callosities not prominent ; coarsely and deeply seriate-punctate, the interstices smooth, rather convex, about the same width as the punctures, feebly, transversely wrinkled, and also very faintly granulate. Ventral segments sparsely and finely, the apex of the fifth coarsely, punctate, the first depressed along the middle. Tibize sulcate on their outer edge. Length 84, breadth 3} millim. (<d.) Hab. Panama, Volcan de Chiriqui (Champion). One specimen, apparently somewhat abraded, the scales on the elytra not forming definite markings. This insect agrees with H. imtegellus in having grooves on the underside of the rostrum (except that they are shallower), as well as in the sulcate tibie; but it differs from that species and other allied forms in the short convex prothorax, the strongly curved rostrum, the subtruncate base of the elytra, the obtuse humeri, &c. The second joint of the funiculus, as in H. integellus, H. sulcicrus, and H. sulcirostris, is much longer than the first. ‘The coarsely granulate prothorax, the less elongate, posteriorly narrowed elytra, &c., separate AH. curvirostris from H. punctatoscabratus. 16. Hilipinus occultus. (Tab. IV. fig. 23, 2.) Hilipus occultus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 90°. Hab. Nicaragua, Chontales! (Belt); Costa Rica (Mus. Brit.); Panama, Bugaba (Champion). This insect is extremely like H. integellus, but it is smaller and less robust, the second joint of the funiculus is relatively longer (not, however, more than twice as long as the first, as stated by Pascoe), and the antennal grooves on the underside of the rostrum are shallower. Of the five specimens before me, one only is of the male sex. 17. Hilipinus guatemalensis, sp. n. Oblong-ovate, slightly shining, piceous ; the elytra with a large irregular patch on the outer part of the disc before the middle, from which a branch extends forward to the base, a large somewhat cruciform patch on the disc at about one-third from the apex, and an apical spot, obscure ferruginous ; the prothorax with an indefinite sinuous vitta on each side, formed by scattered fulvous scales, the elytral markings also clothed with fulvous scales, and sometimes bordered with a few ochreous or whitish ones, the rest of the sparse squamosity of the upper surface obscurely coloured; the under surface and legs with widely scattered, piliform, whitish scales. Head rugosely punctured, obsoletely foveate between the eyes, which HILIPINUS.—TELYS. 61 are somewhat widely separated ; rostrum moderately stout, curved, a little longer than the prothorax, densely, rugosely punctate, carinate, and laterally sulcate, smoother at the tip, in the Q less densely punctate, and much smoother in its apical half; joint 2 of the funiculus nearly twice as long as 1. Prothorax transverse, rounded at the sides, constricted and much narrowed in front and slightly narrowed behind, strongly bisinuate at the base; the surface somewhat closely granulate, a narrow space along the middle and a sinuous one on either side excepted, and with an abbreviated median carina, Elytra convex, about one-third wider than the prothorax, considerably produced at the apex, subparallel at the base, the humeri somewhat angular in front, the apices slightly prominent at the sutural angle; coarsely seriate- punctate, and finely granulate, the interstices transversely rugulose. Venter and metasternum almost smooth, the first ventral segment depressed down the middle in the male. Tibia obsoletely sulcate or a little flattened on their outer edge. Length 9-11, breadth 33-42 millim. (3 2.) Hab. Guatemaa, Cerro Zunil, Senahu, Sinanja (Champion). Six specimens, all more or less abraded. ‘This insect is extremely like H. integellus and H. occultus, the general coloration of the elytra being similar; but the tibiz are less distinctly sulcate, and the humeri are not so angular in front. The second joint of the funiculus is elongate, as in H. occultus, and the grooves on the underside of the male rostrum are formed as in that species, these being shallower than in the same sex of HH. integellus, in which they are separated by an acute ridge. 18. Hilipinus ochreopictus, sp.n. (Tab. IV. fig. 24, 2 :) Oblong-ovate, shining, the head and prothorax duller, black or piceous ; the prothorax with a small spot on each side at the base, and the elytra with one at the shoulder, several others below this, and about six clustered together on the disc at some distance before the apex (in one specimen united into a cruciform patch), ochreous; the rest of the upper surface clothed with minute fuscous scales; the under surface and legs with scattered, narrow, white scales, the propleura with an ochreous spot before the anterior coxe. Head thickly punctured, feebly foveate between the narrowly separated eyes; rostrum a little longer than the prothorax, stout, curved, rugosely punctured, obsoletely carinate towards the base, and sulcate laterally in the ¢, smoother in the 2, the antennal grooves in the male extending shallowly forwards beneath for the reception of the basal joints of the funiculus; joint 1 of the funiculus slightly shorter than 2. Prothorax broader than long, much narrowed in front, the sides rounded anteriorly and almost straight behind; finely and rather sparsely umbilicate-punctate, and with a more or less distinct smooth median line. Elytra about one-fourth wider than the prothorax, subparallel below the base, conjointly rounded at the apex, the humeri angular in front; coarsely seriate-punctate, the interstices flat and each with a single series of minute granules, which become evanescent on the disc before the base. Ventral segment 1 depressed down the middle in the male, 5 coarsely punctured. Tibiz more or less sulcate. Length 9-11, breadth 34-44 millim. (¢ 2.) Hab. Nicaragua, Chontales (Belt, Janson). One male and three females. This species somewhat resembles Hilipus trifasciatus in general coloration, but is really allied to Hilipinus integellus, the antennal grooves in the male extending forwards on the underside of the rostrum for the reception of the basal joints of the funiculus, the tibie are sulcate, and the humeri are angular in front.

Antenne inserted near the tip of the rostrum in the ¢, and at about one-third from the apex in the 9; funiculus 7-jointed, joint 1 much stouter than 2; rostrum much curved and nearly equal in thickness in the 62 RHYNCHOPHORA. two sexes, the scrobes descending to the lower front margin of the eye, the anterior opening only visible from above ; eyes lateral, transverse, separated by a space equalling the width of the rostrum ; prothorax broadly and shallowly arcuato-emarginate at the apex beneath; scutellum transverse, minute ; elytra acutely margined at the base; femora moderately clavate and acutely toothed ; tibie curved, sinuous within, the claw arising from near the inner apical angle ; anterior coxee contiguous, the intermediate pair narrowly, the posterior pair very widely, separated ; metasternum shorter than the first or second ventral segments ; form narrow, elongate, in profile bisinuate. The single species referred to this genus cannot very well be included in Hilipus, even in its extended sense, the scutellum being very minute and the basal margin of the elytra acutely raised. When the prothorax and elytra are closely fitted together and the rostrum is in its normal position, the general profile of the insect is )-shaped, this being partly due to the transversely depressed anterior portion of the elytra. From Lixomorpha, which also has a small scutellum and the basal margin of the elytra raised at the middle, it may be distinguished by the very similarly formed rostrum in the two sexes, the shorter metasternum, the relatively shorter tarsi, &c.; and from Epistrophus, a genus including a single species from Colombia, by the transverse eyes (these being large, rounded, and somewhat depressed in Hpistrophus), the minute scutellum, the shorter metasternum, &c. 1. Telys bisinuatus, sp.n. (Tab. IV. figg. 25, 25a, 2.) Elongate, narrow, moderately convex, slightly shining, black or piceous, the rostrum, antenne, and legs partly rufescent ; above somewhat sparsely clothed with fulvous scales, and with a line of coarse, rounded, ochreous scales running along the sides of the head and prothorax, and round the outer margin of the elytra to a little below the humeri; the under surface sparsely squamose, the pleura with coarse rounded pallid scales; the legs with piliform scales. Head rugulosely punctate, foveate between the somewhat coarsely facetted eyes, smooth beneath; rostrum stout, strongly curved, in the ¢ about as long as the prothorax, rugosely punctured to near the tip, and faintly carinate, in the Q longer and smoother ; joints 1 and 2 of the funiculus subequal in length. Prothorax a little longer than broad, subcylindrical, slightly narrowed in front and behind, strongly bisinuate at the base; densely, rugosely punctate, the narrow interspaces appearing granulate. Elytra elongate, not much wider than the prothorax, flattened on the disc and transversely depressed towards the base, somewhat abruptly narrowed at about one-fourth from the apex, the apices conjointly rounded and produced, the humeri rounded and not prominent ; closely seriate-punctate, the interstices narrow, transversely rugose, and finely granulate, the fourth nodose at one-third from the base and the third at one-third from the apex, the fifth also carinate towards the tip. Beneath coarsely punctate, the first ventral segment broadly depressed down the middle in the ¢. Legs elongate, the femora and tibie rugose, the tarsi smooth and shining above. Length 43-5, breadth 14-2 millim. (¢ @.) Hab. Guatemata, Purula, Senahu, and Sinanja in Vera Paz (Champion). Two males and two females, varying somewhat in the development of the nodiform prominences on the third and fourth elytral interstices. The head is smooth beneath, as in the species of the group Anchonina. LIXOMORPHA, gen. nov. Rostrum exceedingly stout in the ¢, much more slender in the ? ; scrobes deep, descending to the lower anterior margin of the eye, the anterior portion visible from above ; eyes lateral, transverse, not prominent, appearing very narrow as viewed from above; antenne inserted near the apex of the rostrum, the LIXOMORPHA.—ANCHONOMORPHA. 63 funiculus 7-jointed, joint 2 slightly shorter than 1 inthe g and much longer than it in the 9? ; scutellum very small, transverse as seen from above; anterior cox contiguous, the intermediate pair very narrowly separated ; metasternum about as long as the first ventral segment, the episterna very narrow in the Q, broader in the ¢ ; legs long and rather slender, the femora moderately clavate and armed with a short tooth towards the apex, the tibiz sinuous and furnished at the inner apical angle with a sharp claw, which is preceded by two matted spine-like tufts of hair, the tarsi elongate. This genus, which includes a single species from Costa Rica *, is closely related to Hilipus (Sect. I.), but differs from it in the small transverse scutellum, the feebly dentate femora, the laterally placed eyes (which are separated by a space fully equalling the width of the rostrum), &c. In general facies, Livomorpha resembles Callinotus and Desmosomus, of the group Cholina, but in these latter the anterior and intermediate coxee are more or less widely separated. The sexual differences in the form of the rostrum and antenne are very remarkable. The genera Cheris, Pasc., and Hpistrophus and Ischiomastus, Kirsch, also have the eyes similarly placed, but they are not other- wise very nearly related to Lixomorpha. 1. Lixomorpha albomarginata, sp.n. (Tab. IV. figg. 26, 26a, 3; 27, 2.) Elongate, subfusiform, opaque, the rostrum and under surface shining ; the head, prothorax, and elytra each with a marginal stripe of white or pale ochreous scales, those on the head narrow and the others rounded, the rest of the surface with widely scattered similarly coloured scales. Head shallowly foveate between the eyes, almost smooth ; rostrum moderately curved, in the ¢ a little shorter than the prothorax, closely punctured at the sides, smooth at the tip, carinate along the middle, and about one-half the width of the apex of the prothorax, in the Q@ longer and smoother, cylindrical, and comparatively slender ; joint 2 of the funiculus a little shorter than 1 in the g, and at least twice as long as it is in the Q. Prothorax as long as broad, subconical, narrowing from a little before the base to the apex, the base deeply bisinuate, the surface with extremely minute, scattered, shallow punctures, and with indications of a smooth raised median line. Elytra elongate, much wider than the prothorax, narrowing almost from the base, conjointly rounded at the apex, flattened on the inner part of the dise and obliquely sloping towards the outer margin, the base trisinuate and with the margin raised and thickened on either side of the scutellum ; seriate-punctate, the interstices flat and almost smooth, the third appearing a little raised, but not callose towards the tip. Venter sparsely punctate, and in the ¢ with a broad, deep, oval depression extending down the middle of the first and second segments. Length 11-13, breadth 4-42 millim. (¢ @.) Hab. Costa Rica, Rio Sucio, lrazu (Logers). Two females from Irazu and a male from Rio Sucio, all in a rather bad state of preservation. ANCHONOMORPHA, gen. nov. Antenne inserted near the apex of the rostrum, funiculus 7-jointed, joint 1 stouter than those following ; rostrum stout, similar in form in the two sexes, the scrobes deep, visible from above in front, descending to the lower anterior margin of the eye; eyes coarsely facetted, lateral, separated by a space fully as wide as the rostrum, transverse, narrow and oblique as seen from above; prothorax very deeply and abruptly arcuato-emarginate at the apex beneath, the prosternum broadly depressed along the middle; scutellum small, oval ; elytra with series of rounded or oblong squamigerous prominences ; anterior coxze contiguous ; * There is an undescribed species from Colombia in the British Museum, labelled Heilipus callinotoides, Jekel, that may belong to it. 64 RHYNCHOPHORA. first and second ventral segments connate at the middle; metasternum short; femora strongly clavate and acutely toothed ; tibia sinuous within, the claw arising near the inner apical angle in the ¢, and from about the middle of the apical margin in the 9, in which sex the inner apical angle is more or less mucronate, and also furnished with two matted spine-like pencils of hair at the tip; penultimate tarsal joint bilobed. , The three species referred to this genus, which will also include at least one South- American form, are very like some of the members of the group Anchonina, from which they may be distinguished by the more exserted, strongly punctured, and less globose head. The very widely separated eyes, the partially connate first and second ventral segments, and the peculiar sculpture of the upper surface separate them from Hilipus, to which otherwise they are closely allied. The fusion of the first two ventral segments is a character common to most of the Anchonina. 1. Anchonomorpha occulta, sp.n. (Tab. IV. figg. 28, 28a, 2.) Oblong-ovate, dull above and shining beneath, black, the antenne and tarsi partly rufescent ; clothed above with scattered, narrow, minute, brownish scales, these being coarser and more elongate on the elytral elevations, the entire upper surface often coated with an earthy incrustation ; the under surface with very few scales; the legs thickly clothed with curved setiform scales. Head densely punctate, foveate between the eyes; rostrum stout, slightly longer than the prothorax, moderately curved, rugosely punctured, 5-carinate ; joints 1 and 2 of the funiculus subequal in length. Prothorax a little broader than long, rounded at the sides anteriorly, considerably narrowed in front, and slightly so behind, the base strongly bisinuate; the surface densely, rugosely punctured, somewhat uneven towards the apex, two feeble elevations being sometimes visible on the disc before the middle. Elytra fully one-half wider than the prothorax, moderately long, parallel in their basal half, conjointly rounded at the apex, the base feebly trisinuate, the humeri rounded ; seriate-punctate, the interstices 2-7 each with a scattered row of oblong or rounded elevations, those on the third and fifth being the most conspicuous. Metasternum foveolate at the sides. Ventral segments 1-4 very sparsely and finely, and 5 closely, punctate, the latter transversely depressed in the middle at the apex in the ¢. Length 6-9, breadth 24-4 millim. (¢ 2.) Hab. Mexico, Toxpam (Sallé); Guatemata, Sinanja in Vera Paz (Champion) ; Nicaragua, Chontales (Belt); Costa Rica, Tucurrique (Mus. Dresden); Panama, Bugaba, Volcan de Chiriqui (Champion). Found in plenty in Chiriqui. Differs from the following species in the absence of the prominences on the prothorax, though two of these are sometimes traceable on the disc. 2. Anchonomorpha tuberculifera, sp. n. (Tab. V. fig. 1.) Oblong-ovate, broad, opaque above and slightly shining beneath, pitchy-black, the legs and antenne partly rufescent; clothed above with minute brown scales, these being coarser and more elongate on the elytral elevations, and also with scattered, short, erect setae, the inequalities of the surface more or less coated with an earthy incrustation ; the under surface with a few scattered scales and erect sete; the legs with setiform scales. Head densely punctate, foveate between the eyes; rostrum moderately curved, stout, rugosely punctured, 5-carinate; joint 2 of the funiculus slightly shorter than 1. Prothorax a little broader than long, the apex produced over the base of the head and emarginate in the centre, the sides rounded at the middle, rapidly converging in front, and sinuate behind, the base strongly bisinuate; the surface uneven, closely, irregularly punctate, with six prominent rounded tubercles—four in a transverse ANCHONOMORPHA.—RHECAS. 65 series across the middle and one on each side immediately in front of the outer one,—the disc also longitudinally raised on either side of the middle in a line with the two median tubercles, forming two conspicuous ridges in front. Elytra moderately long, rather more than one-half wider than the prothorax, conjointly rounded at the apex, subparallel in their basal half, the humeri prominent, rounded; seriate- punctate, the interstices 2-7 each with scattered, large, subconical tubercles. Beneath very coarsely sparsely punctate. Length 83-10, breadth 33-42 millim. ( 9.) Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). Five specimens. Broader than A. occulta, and with stouter tubercles on the elytra, the pronotum also conspicuously tuberculate and produced in front over the base of the head, the under surface coarsely punctate and sparsely setose. 3. Anchonomorpha debilis, sp. n. Oblong-ovate, shining, black or piceous, the antenne and legs partly rufescent; clothed above with minute brownish scales and short sete, which are partly hidden by an earthy incrustation ; the under surface with a few scattered scales; the legs setose. Head and rostrum densely rugulosely punctate, the latter moderately stout and about as long as the prothorax, not carinate; joint 2 of the funiculus a little shorter and much more slender than 1. Prothorax broader than long, somewhat produced in front over the base of the head, constricted before the apex, the sides rounded at the middle, rapidly converging in front, and slightly sinuate behind, the base bisinuate ; the surface uneven, densely rugulosely punctate, with four conical tubercles placed in an irregular transverse series across the middle and two prominences at the apex. Elytra fully one-half wider than the prothorax, subparallel in their basal half, conjointly rounded at the apex; coarsely seriate-punctate, the interstices 2-7 with scattered oblong elevations. Beneath sparsely punctate; the first ventral segment broadly depressed in the middle, and the fifth emarginate at the apex and also slightly depressed down the centre, in the ¢. Length 33-4, breadth 13-13 millim. (¢ @.) Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). Five specimens. This species is allied to A. tuberculifera, but it is very much smaller and has fewer tubercles on the prothorax, and the rostrum is not carinate. RHECAS, gen. nov. Mandibles with a tridentate, downwardly curved, acute edge; rostrum very stout, curved, the scrobes deep, descending to the lower anterior margin of the eye and commencing on the upperside; mentum transverse, placed at the apex of a long peduncle, the palpi visible ; antenn inserted near the apex of the rostrum in both sexes, the funiculus 7-jointed, joint 7 larger than 6; eyes lateral, transverse, not prominent, separated by a space equalling the width of the rostrum; prothorax and elytra closely articulated and truncate at the base, the prothorax deeply arcuate-emarginate at the apex beneath, the elytra connate ; scutellum absent ; anterior cox contiguous ; metasternum short ; ventral sutures very deep, the segments 2-4 convex, and 2 scarcely as long as 3 and 4 united; legs stout; femora clavate, concave at the apex beneath, almost unarmed; tibiz sinuous within, armed with a short claw at the inner apical angle, the apex oblique, ciliate on the inner and outer edges; tarsi short, not half the length of the anterior or posterior tibia, spongy-pubescent beneath, the third joint bilobed; body apterous. The single species referred to this genus has very much the appearance of an Otiorrhynchid, but the mandibles are formed as in the Hylobiina and the other characters are as in that group, with the exception of the deep ventral sutures. It is perhaps nearest allied to Laccoproctus, which also has the prothorax and elytra BIOL. CENTR.-AMER., Coleopt., Vol. 1V. Pt. 4, October 1902.

Rhecas spurcus, sp.n. (Tab. V. figg. 2, 2a, 3.) Elongate-ovate, rather convex, opaque, the rostrum and under surface shining, black, the tarsi and antenne sometimes partly rufescent ; the prothorax and elytra somewhat thickly clothed with coarse, piliform, brown scales, which are partly hidden by an earthy incrustation, the under surface very sparsely squamose, the legs with clubbed setiform scales and an earthy coating. Head densely rugulosely punctate above, transversely strigose beneath ; rostrum (¢) nearly as long as the prothorax, rugosely punctured to near the tip, and 5-carinate, ( 2) slightly longer, smoother, and faintly carinate at the sides only ; joints 1 and 2 of the funiculus equal in length, 7 as long as broad, stouter than 6. Prothorax about as long as broad, rounded at the sides anteriorly, much narrowed in front, and slightly so behind, the hind angles subrectangular ; the surface somewhat uneven, minutely punctate, and with four rounded prominences on the disc.

Gvatemata, San Juan, Senahu and Purula in Vera Paz (Champion). Seven specimens. The only sexual difference observable is in the sculpture of the rostrum. LACCOPROCTUS. Laccoproctus, Schénherr, Gen. Cure. vii. 2, p. 154 (1843); Lacordaire, Gen. Col. vi. p. 460. A monotypic genus peculiar to Mexico and Guatemala. Neither Lacordaire nor Schénherr noted that the mandibles in Laccoproctus are narrow and quite simple at the edge, whereas in Hilipus and its allies they are broad and tridentate. 1.

The males differ from the females in having the rostrum a little shorter and more rugose, and also faintly carinate. Group ANCHONINA™*. Anchonine, Faust, Deutsche ent. Zeit. 1892, p. 19. The species of this group, which are nearly all Tropical American, are recognizable by their globose, deeply inserted, almost smooth head, and the stout, curved, deflexed * We are indebted to Dr. K. M. Heller, of the Dresden Museum, for the loan of cotypes of various species of this group described by Faust. ONCORRHINUS. 67 rostrum. The eyes in the typical genera (Anchonus, &c.) are depressed and finely facetted, and placed low down on the globular portion of the head, whereas in INoptrophorus, Ithaura, and Theognete they are more or less coarsely facetted and placed at the sides of the rostrum behind. ‘The funiculus of the antenne is 8-jointed in Anchonus, Rhyparonotus, Cestophorus, and Leprosomus (the two last-mentioned genera have not yet been detected in Central America), 7-jointed in Oncorrhinus, Dioptro- phorus, &c., and 6-jointed in Geobyrsa (Anephilus). All are apterous, except Oncorrhinus, which has a scutellum and fully-developed wings. The apterous species, as might be expected, are extremely local, and each confined to a limited district, the winged forms, on the other hand, being somewhat widely distributed. These insects are chiefly found under the bark of decaying trees, or by beating dead branches, and some of them are often thicklycoated with an earthy incrustation, which hides most of the surface-sculpture. I have found it impossible in many cases to identify specimens till they were cleaned by immersion in caustic potash, which removes the dirt without loosening the scales. In Anchonus and its allies the scales on the upper surface of the body are more or less setiform, and sometimes clubbed at the tip ; they vary in length according to the species, and are often arranged in fascicles on the prothorax and on the more elevated portions of the elytra. Zyphloglymma, Dury, including a blind form from Ohio, belongs to this group, near Jthaura. | Sect. I. Eyes placed low down on the globular portion of the head. ONCORRHINUS.

In Lacordaire’s figure of O. scabricollis (Gen. Col., Atlas, t. 69. fig. 1) the elytra are represented as uninterruptedly carinate from the base to the apex. 2. Oncorrhinus latipennis, sp. n. (Tab. V. fig. 5, 3.) Broad, moderately convex, black, the tarsi and antenne piceous or rufo-piceous, sparsely setose. Rostrum seriate- punctate, shining at the apex, with a smooth median carina, the apical portion short in the d, and much longer and almost entirely smooth in the 9; head deeply foveate in the middle in front. Prothorax flattened on the disc, transversely quadrate, strongly bisinuate at the base and apex, the anterior lobe considerably produced, the sides hollowed towards the base, the hind angles acute (as seen from above) ; the surface (except in the hollow space on each side of the anterior lobe) very coarsely, irregularly, foveolato-punctate, the punctures here and there confluent, and the interspaces sinuously raised and shining, the disc sometimes with indications of an irregular, abbreviated, median carina. Elytra mode- rately convex, somewhat heart-shaped, at the base strongly trisinuate and fully one-half broader than the prothorax, gradually narrowing from the prominent and obliquely subtruncate humeral callosities ; finely and shallowly seriate-punctate, the punctures becoming evanescent towards the apex, the interstices each with a scattered series of small, rounded, shining tubercles, each of these bearing a stout, decumbent, ochreous, piliform scale, the third subcarinate at the base.

Nearly one hundred species of Anchonus have been described, mostly from the Antilles or the mainland of Tropical America, the genus extending from Florida to Chile, and also occurring in the Galapagos and Cocos Islands; it is extremely well represented within our limits. The chief characters of the genus are the 8-jointed funiculus and the contiguous anterior coxe, Cestophorus differing from it in having a * There are specimens of another closely allied form, labelled as from Mexico and Brazil, in the British Museum; but this insect has the prothorax longer and more parallel-sided, with a less pronounced anterior lobe, and the entire surface foveolato-punctate, the rostrum smoother, and the head trifoveate.

LElytra ovate, convex, at the middle considerably wider than the prothorax, but very little broader than it at the base, the basal margin raised and sinuous ; seriate-punctate, the interstices 2-7 each with a series of small setigerous tubercles, those at the base of 3 and 5 sometimes forming a short ridge. Beneath very sparsely punctate. Ventral segments 1 and 2 separated by a rather deep suture. Femora coarsely punctate. Length 53-72, breadth 23-34 millim. (¢ 2.) Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). ANCHONUS. Tt Ten specimens, most of them encrusted with dirt, and varying greatly in size. In this species, as in the allied A. articulatus, the first two ventral segments are separated by a deep suture (instead of being fused together at the middle, as usual in this genus). The setosity is short and scattered, not forming fascicles on the prothorax. The prothorax is coarsely, closely punctate, with the raised interspaces smooth, shining, and subgranulate. The elytral tubercles are small. 4, Anchonus mirus. (Tab. V. fig. 9, 9a, ¢; 96, antenna.) Anchonus mirus, Faust, Deutsche ent. Zeit. 1892, pp. 28, 48 (¢)’. Elongate, moderately convex, deep black, the antenne and tarsi obscurely rufescent; the sete short, coarse, and very scattered, but forming four small fascicles on the prothorax. Rostrum stout, cylindrical, curved, coarsely punctate to the tip, the widened apical portion rather long in both sexes, but a little longer and narrower in the ¢ than in the 9; antenne stout, the funiculus short, joint 2 barely twice as long as 1, 7 and 8 transverse, 8 nearly as wide as the club. Prothorax slightly longer than broad, widest a little before the middle, broader and more rounded at the sides in the ¢ than in the @, deeply constricted before the apex and much narrowed behind; the surface trisulcate, extremely coarsely rugose, with the ruge sinuous or transverse and shining at the summit, binodose and fasciculate at the apex and on the middle of the disc; the flanks very coarsely punctate. Elytra oblong-ovate, at the base wider than the prothorax ; very coarsely seriate-punctate, the interstices transversely rugose, conspicuously tuberculate, and granulate, the elevations tending to coalesce and form interrupted caring, especially at the base of the third and fifth interstices. Beneath very coarsely punctate. Femora shallowly, somewhat finely punctate. Third tarsal joint moderately dilated, not very deeply excised at the apex. Length 65-7, breadth 2-24 millim. (¢ 9.) Hab. GuateMALa !, Totonicapam (Champion), Tecpam (Conradt). We possess seven specimens of this species, all from a high elevation in the Los Altos region. The stout and comparatively short antenne, with strongly transverse eighth funicular joint, and the somewhat feebly dilated third tarsal joint, separate A, mirus* from the other Central-American forms, the following excepted. The antenne in the male are inserted further from the apex than usual in this genus, so that there is very little difference observable in the form of the rostrum in the two sexes. 5. Anchonus mexicanus, sp. n. (Tab. V. figg. 10, 10a, ¢.) Oblong-ovate, black, the antennz and tarsi partly rufescent; the sete extremely short, scattered, and incon- spicuous. Rostrum stout, curved, shorter than the prothorax, feebly constricted at the base, rugosely pune- tured and longitudinally wrinkled, the scrobes extending along the underside; antenne stout, the funiculus short, joints 7 and 8 transverse, 8 nearly as wide as the club, and much wider than 7. Prothorax longer than broad, rounded at the sides, narrowing and strongly constricted in front and narrowing behind; the surface, except along a narrow smooth space down the middle, very coarsely, irregularly punctate, the interspaces here and there sinuously raised and shining on the disc and granulate at the sides, Elytra oblong-ovate, at the base slightly wider than the prothorax ; seriate-punctate, the interstices transversely wrinkled and finely granulate, 2-7 each with a series of oblong or rounded, not very prominent, tubercles, * Dr. Heller has been kind enough to compare one of our specimens with the type. 72 RHYNCHOPHORA. these forming carine at the base of 3 and 5, and all finely granulate. Beneath and the femora coarsely punctate. Third tarsal joint moderately dilated, not very deeply excised at the apex. Length 6-64, breadth 23-24 millim. (<.) Hab. Muxico, Mexico city (Hoge). Three specimens. Allied to the Guatemalan A. mirus, but less elongate, with the rostrum shorter and slightly constricted at the base, the antenne not quite so stout, the prothorax less rugose, with much more definite punctuation, the elytra with less prominent, finely granulate elevations. The distinctly constricted rostrum and the form of the antenne, &c. separate it from A. elongatus and various other Mexican forms. In dirty specimens the small, smooth, granular elevations are conspicuous on both the prothorax and the elytra. 6. Anchonus gibbirostris, sp. n. (Tab. V. figg. 11, lla, 8, ¢.) Elongate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the setee rather long and coarse, and arranged into fascicles on the prothorax and elytra. Rostrum (¢) stout, cylindrical, strongly curved, gibbous above near the base, densely, rugosely punctate and minutely granulate to the tip, (2 ) coarsely, closely punctate, smoother at the tip. Prothorax slightly longer than broad, narrowed behind and constricted in front, flattened on the disc, the sides rounded at the middle; the surface irregularly granulate, except along the depressed median space and a sinuous space midway between this and the margin, which are smooth, and with two more or less distinct setigerous elevations at the apex and two more on the disc; the flanks coarsely punctate. Hlytra ovate, convex, wider than the prothorax, but of about the same width at the base, interruptedly seriate-punctate, the interstices 2-7 each with a scattered series of oblong or rounded, prominent, setigerous, faintly granulate tubercles, the basal margin raised. Beneath very coarsely, sparsely punctate. Femora coarsely punctate and minutely granulate. Length 54-64, breadth 23-3 millim. (¢ 9.) Hab. GuateMaLa, Senahu and San Juan in Vera Paz (Champion). Twelve specimens, from a limited district in the forest-clad mountains to the north of the Polochic Valley. Distinguishable from all the other Central-American species of the genus by the gibbous rostrum. The elevations on the prothorax are partly formed by the fasciculate arrangement of the sete, those on the elytra being more prominent. The rostrum is not constricted at the base. 7. Anchonus nodosus, sp. n. (Tab. V. figg. 12, 124, ¢.) Anchonus nodosus, Chevr. in litt. Elongate, very convex, black, the antenne and tarsi obscurely rufescent; the sete very short and scattered. Rostrum (¢) stout, cylindrical, strongly curved, coarsely punctate to the tip, feebly constricted at the base, ( 2 ) slightly thickened towards the base, and smoother and more shining at the apex; joint 2 of the funiculus twice as long as 1. Prothorax about as broad as long, nearly or quite as wide as the elytra, strongly constricted behind and also before the apex, the sides rounded ; the surface very uneven, coarsely nodose and granulate laterally and also along either side of the depressed median space, for the rest smooth ; the flanks coarsely punctate. LElytra at the base very little wider than the prothorax, convex, ovate; each with about twelve very prominent, large, rounded or oblong, granulate elevations on the dise and scattered smaller tubercles towards the sides, between which seriate punctures are visible. Beneath shining, very coarsely punctate. Femora granulate. Length 7-10, breadth 3}-43 millim. (¢ 2.) ANCHONUS. 73 Hab. Mexico (Mus. Brit.), Sierra de Durango (Flohr), Orizaba, Toxpam (Sal/é), Jalapa (Hoge). This is the largest and most distinct of the Central-American Anchoni; it is not rare in the State of Vera Cruz, whence we have received a long series. The tubercles on the elytra are large and very prominent, though variable in size, and there are also six on the disc of the prothorax and two oblong prominences at the apex in the middle. The prothorax appears to be transversely gibbous and trisulcate in the specimens with very prominent elevations on the disc. In one of those from Durango the tubercles of the elytra are smaller than usual. 8. Anchonus silvicola, sp. n. (Tab. V. figg. 13, 134, 3.) Elongate, black, the antenne and tarsi obscurely rufescent; the sete rather long and coarse and arranged in fascicles on the prothorax and elytra. Rostrum (¢) stout, curved, cylindrical, rugosely punctate to the tip and obsoletely carinate, (2 ) smoother and shining at the tip. Prothorax about as long as broad, a little flattened on the disc, rounded at the sides, much narrowed in front and behind, and moderately constricted before the apex ; the surface sparsely granulate, except along the broad depressed median space and a sinuous space midway between this and the margin, which are smooth, with two feeble setigerous prominences at the apex and two or more on the disc; the flanks sparsely punctate. LElytra a little broader than the prothorax, and of about the same width at the base, convex, ovate, coarsely seriate-punctate, the interstices 2-6 each with a scattered series of oblong, prominent, setigerous, finely granulate tubercles, the basal margin raised. Beneath coarsely, sparsely punctate. Femora coarsely punctate and obsoletely granulate. Length 54-64, breadth 2-23 millim. (¢ 2.) Hab. Guatemaua, Sinanja, Sabo, and Purula in Vera Paz (Champion). Seven specimens, from the mountains to the south of the Polochic Valley. Very like A. gibbirostris, but easily separable therefrom by the non-gibbose rostrum, which is also less densely punctate and obsoletely carinate, with the widened apical portion relatively shorter in the male. Two females from Cerro Zunil, on the Pacific slope, may belong here; but they have the granular elevations on the prothorax more numerous and tending to form transverse or sinuous ruge, and the rostrum very slightly thickened towards the base. ‘The less rugose surface, and the prominent, scattered, fasciculate tubercles on the elytra, the elytra themselves being less widened at the base, distinguish this species at once from A. elongatus. 9, Anchonus carinirostris, sp.n. (Tab. V. figg. 14, 14a, ¢.) Oblong, black or piceous, the antenne and tarsi more or less rufescent ; the sete coarse, scattered, semierect, and arranged in fascicles on the prothorax and elytra. Rostrum (<¢ ) curved, distinctly thickened towards the base and there very feebly constricted, coarsely seriate-punctate, with the interspaces finely carinate, (2) shining and sparsely, finely punctate at the tip. Prothorax broader than long, somewhat flattened on the disc, nearly as wide as the elytra, the sides much dilated at the middle and abruptly constricted before the apex ; the surface sparsely punctate and minutely granulate laterally and along each side of the broad flattened median space, and binodose at the apex and on the disc, for the rest smooth. Elytra slightly wider at the base than the prothorax, convex, ovate, with interrupted rows of shallow, somewhat widely separated punctures, the interstices 2-7 each with a scattered series of setigerous tubercles, those BIOL.

In this species the sculpture of the prothorax and elytra is similar to that of A. gibbirostris, from which the present insect differs in its much smaller size and less elongate shape, the carinate non-gibbose rostrum, the transverse prothorax, &c. The prothorax 1s quite smooth down the middle and along a sinuous space between this and the margin. 10. Anchonus penicillatus, sp.n. (Tab. V. figg. 15, 15a, ¢.) Oblong, black, the antennz and tarsi more or less rufescent ; the setz coarse, rather long, semierect, forming six fascicles on the prothorax. Rostrum (¢) curved, subeylindrical, coarsely punctate to the tip, and longitudinally wrinkled, (2) shining and more sparsely punctate at the tip. Prothorax broader than long, much narrowed behind and narrowed and abruptly constricted in front, narrower than the elytra ; the surface granulate, except down the middle and along a narrow sinuous space midway between this and the margin, binodose at the apex, and with an abbreviated median carina. Elytra ovate, slightly wider at the base than the prothorax, coarsely seriate-punctate, the interstices 2-7 each with a series of setigerous tubercles, the suture also tuberculate beyond the middle. Beneath very coarsely punctate. Femora closely, coarsely punctate. Length 4-5}, breadth 2-23 millim. (¢ 9.) Hab. Guaremata, Senahu, San Juan, Sinanja, Sabo, San Gerdnimo (Champion), Coban (Conradt). Not rare in the humid forest districts of Alta Vera Paz. Chiefly distinguishable by the granulate, faintly carinate, fasciculate, posteriorly narrowed prothorax, the seriate- tuberculate, ovate elytra, the roughly punctured femora, and the coarse semierect setosity. The less dilated and more closely granulated prothorax, the non-carinate rostrum, &c., separate it from A. carinirostris, an insect inhabiting the same districts. 11. Anchonus abnormis. (Tab. V. figg. 16,164, 2.) Anchonus abnormis, Fahr. in Schonh. Gen. Cure. vii. 2, p. 893°. Hab. Mexico (coll. Chevrolat}, in Mus. Holm.). The type of this small species, a female, has been lent me by Dr. Aurivillius. It is in very dirty condition, but may be recognized by the prominent tuberculiform elevations on the prothorax and elytra; the interspaces on the prothorax are sparsely ‘granulate; the scape reaches to the middle of the eyes, which are rather large ; the under surface is very sparsely, finely punctate; the seriate punctures on the elytra are very coarse and deep towards the sides; the femora are comparatively smooth. Length 43 millim. | A, abnormis was not noticed by Faust in his papers on the genus. ANCHONUS. (oy 12. Anchonus obovatus, sp. n. (Tab. V. figg. 17, 174, 3.) Obovate, robust, convex, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the set coarse, rather long, forming conspicuous erect fascicles on the prothorax and on the elytra, chiefly placed on the elevated portions of the surface. Rostrum stout, curved, cylindrical, closely, rugosely punctate to the tip, not carinate; joint 2 of the funiculus about twice as long as 1. Prothorax about as broad as long, narrowed and constricted in front and narrowed behind, the sides rounded at the middle; the surface closely punctate, in some specimens with a smooth slightly raised median line, binodose and fasciculate at the apex, and with two other fascicles on the disc and one on each side before the middle. Elytra ovate, convex, at the middle fully one-half wider than the prothorax, but at the base scarcely wider than it, seriate-punctate, the interstices 2-6 each with a scattered series of very prominent oblong or rounded setigerous tubercles, the suture also tuberculate beyond the middle. Beneath coarsely, sparsely punctate. Femora coarsely punctate. Length 6-7, breadth 3-34 millim. (d @.) Hab. Costa Rica, Tucurrique (Mus. Dresden); Panama, Volcan de Chiriqui (Champion). Eighteen specimens, mostly in very clean condition. A rather large, convex species, of obovate form, with the rostrum coarsely punctate to the tip in both sexes, the prothorax coarsely, rugosely punctate and conspicuously fasciculate, and the elytra with prominent setigerous tubercles. There is no trace of granulation on the pro- thorax, the punctures appearing variolose in dirty examples. 13. Anchonus validus, sp. n. Obovate, robust, convex, black ; the sete coarse and rather long, forming fascicles on the prothorax and on the elytra, chiefly placed on the elevated portions of the surface. Rostrum very stout, curved, cylindrical, a little longer than the prothorax, densely, rugosely punctate, not carinate; joint 2 of the funiculus nearly three times as long as 1. Prothorax broader than long, narrowed and constricted in front and. narrowed behind, the sides rounded at the middle; the surface densely, rugosely punctate, the intervening ruge here and there transversely confluent. Elytra ovate, convex, at the middle about one-half wider than the prothorax, seriate-punctate, the interstices 2-6 each with a scattered series of moderately prominent oblong setigerous tubercles, those on 2 and 3 larger and more conspicuous than the rest. Legs very stout, the femora coarsely, rugosely punctate. Length 73, breadth 4 millim. (¢-) Hab. Guaremana, San Juan in Vera Paz (Champion). One specimen, from the vicinity of the Polochic Valley. Very like A. obovatus, from Costa Rica and Chiriqui, but larger and more robust, the prothorax transverse, relatively broader, and with the ruge transversely confluent, the elytral elevations less prominent, especially towards the sides, the tibie straighter. 14. Anchonus nodipennis, sp.n. (Tab. V. figg. 18, 184, ¢.) Obovate, convex, black, the funiculus and tarsi obscurely rufescent, thickly clothed with an earthy incrustation ; the sete short, fine, and scattered, but coarser, longer, and clustered together on the elevated portions of the surface, forming eight fascicles on the prothorax. Rostrum stout, cylindrical, feebly curved, coarsely, seriately punctate. Prothorax transverse, somewhat flattened on the disc, dilated at the sides a little before the middle, gradually narrowing thence to the base and abruptly constricted and narrowed in front; the surface very closely, coarsely punctate, with the narrow raised interspaces here and there shining and granulate, distinctly binodose at the apex and on each side before the middle, and less LL 2 76 RHYNCHOPHORA. distinctly so on the disc, the disc with indications of an abbreviated median carina. LElytra subelliptic, convex, wider at the base than the prothorax, seriate-punctate, the interstices 2-7 each with a series of oblong or rounded, prominent, setigerous tubercles, those at the base of 3 and 5 cariniform, the suture also tuberculate a little beyond the middle. Beneath very coarsely punctate, the ventral segments 1 and 2 connate. Femora coarsely punctate and minutely granulate. Length 63-8, breadth 33-37 millim. (<¢.) Hab. Nicaragua, Chontales (Belt). Two males. In this species the prothorax is distinctly binodose on each side before the middle, so as to appear subangularly dilated. It is not unlike A. obovatus and A. validus, but has a more transverse, finely granulate prothorax ; the elytra are less rounded at the sides, broader at the base, and with more numerous tubercles, these being not so prominent as in A. obovatus; and the setosity is shorter. 15. Anchonus helleri, sp. n. (Tab. V. figg. 19,19 a, ?.) Oblong-obovate, slightly depressed above, black ; the sete coarse and forming fascicles on the prothorax and elytra. Rostrum moderately stout, slightly thickened towards the base, coarsely punctate. Prothorax a little broader than long, constricted and much narrowed in front and gradually narrowing behind, coarsely varioloso-punctate, with the narrow interspaces here and there granulate, distinctly binodose at the apex and also on each side before the middle, and with the sete clustered together at these places, the disc with an abbreviated sinuous smooth median line anteriorly. Elytra oblong-ovate, at the base a little broader than the prothorax, seriate-punctate, the interstices 2-7 each with a scattered series of oblong or rounded setigerous tubercles, those at the base of 3 and 5 forming a short ridge, the suture granulate. Beneath somewhat coarsely punctate; ventral segments 1 and 2 connate and level at the middle. Length 8, breadth 41, millim. (9.) Hab. Costa Rica, Piedras Negras (Mus. Dresden). One specimen, communicated by Dr. Heller. Not unlike A. horridus, but much larger, with a rougher fasciculate prothorax, which is binodose laterally and in front. The connate first and second ventral segments, the narrower terminal joint of the funiculus, and the less rounded sides of the prothorax and elytra separate it from A. articulatus and A. brevisetis; and the more depressed form, &c., from A. obovatus and A. validus. 16. Anchonus subcristatus, sp. n. (Tab. V. figg. 20, 204, 3.) Elongate-ovate, black, the antenne and tarsi obscurely rufescent; the sets long, coarse, and abundant, and showing a tendency to form four fascicles on the prothorax. Rostrum (¢) curved, stout, cylindrical, slightly constricted at the base, coarsely punctate and longitudinally wrinkled, ( 2 ) slightly thickened towards the base, and closely, coarsely punctate to the tip. Prothorax about as long as broad, a little shorter in the 2, the sides rounded at the middle, converging thence to the base and apex, and constricted in front; the surface closely punctate, except along a narrow space down the middle, with the inter- spaces opaque and here and there transversely or obliquely raised, feebly binodose and fasciculate at. the apex, the set also forming two indistinct fascicles on the disc. Elytra ovate or oblong-ovate, convex, at the base scarcely wider than the prothorax ; seriate-punctate, the interstices 2-7 each with a series of oblong or rounded prominent setigerous tubercles, the suture also tuberculate. Femora coarsely punctate. Length 44-5, breadth 2-23 millim. (¢ 2.) ANCHONUS. qT Hab. Guaremata, Cerro Zunil, Pacific slope (Champion). Three males and one female, varying a little in the length of the prothorax and elytra. This is one of several very closely allied Guatemalan forms. From A. cirratus, of the Atlantic slope, it may be separated by the less dilated prothorax (especially noticeable in the males), the sete on which form about four fascicles only, the more closely tuberculate elytra, and the rostrum in both sexes coarsely punctate to the tip, it also being more thickened towards the base in the female. From A. coarctatus, from the same district, the less constricted base of the prothorax and of the elytra, and the more closely punctured and less uneven surface of the former, will serve to distinguish it. 17. Anchonus coarctatus, sp.n. (Tab. V. figg. 21, 21a, 2.) Elongate-ovate, narrow, black, the antenne and tarsi rufescent; the sete coarse, forming fascicles on the prothoracic and elytral elevations. Rostrum cylindrical, strongly curved, stout, coarsely seriate-punctate, distinctly carinate down the middle and obsoletely so towards the sides. Prothorax as long as broad, widest at the middle, sinuously narrowing thence to the base, and narrowing and constricted in front, the hind angles subrectangular: the surface very uneven, coarsely, closely punctate, except along a narrow depressed space down the middle, binodose at the apex and also on the middle of the disc, and podose at the sides, the elevations conspicuously fasciculate, the interspaces between the punctures here and there raised and faintly granulate. Elytra convex, ovate, constricted at the base and there a little wider than the prothorax, the basal margin appearing raised and the humeri rather prominent; coarsely seriate-punctate, the interstices 2-5 each with a scattered series of very prominent, oblong, setigerous tubercles. Femora somewhat finely punctate. . Length 44, breadth 2 millim. (d.-) Hab. Guaremata, Cerro Zunil, Pacific slope (Champion). Two males. Recognizable amongst its allies, A. subcristatus, &c., by the constricted base of the prothorax and of the elytra, the carinate rostrum, the uneven, rugose, and conspicuously fasciculate prothorax, and the prominent setigerous tubercles on the interstices 2-5 of the elytra. 18. Anchonus cirratus, sp. n. Oblong, black or nigro-piceous, the antenne and tarsi more or less rufescent; the sete long, coarse, and semi- erect, forming numerous fascicles on the prothorax and elytra. Rostrum (¢) curved, slightly thickened towards the base, and there very feebly constricted, coarsely punctate, obsoletely 5-carinate, (9) more thickened towards the base, finely punctured and shining at the tip. Prothorax broader than long, somewhat flattened on the disc, a little rounded at the sides, much narrowed behind, and narrowed and constricted in front ; the surface rather uneven, closely varioloso-punctate, except along a narrow space down the middle, and more or less distinctly binodose in front, the sete arranged in about twelve conspicuous fascicles—three down each side of the middle of the dise and three on each lateral margin. Elytra ovate, convex, about as wide at the base as the prothorax, coarsely seriate-punctate, the interstices 2-7 each with a widely scattered series of setigerous tubercles.

Twelve examples. ‘his is a species with a closely varioloso-punctate prothorax, on which the ochreous sete are clustered together in about twelve fascicles—a double series down the middle of the disc and one on each lateral margin. The rostrum is conspicuously thickened towards the base in the female, and slightly so in the male. The elytra are similar in shape and sculpture to those of A. penicillatus and other allied forms. ‘The peculiar sculpture of the prothorax distinguishes it from many very similar species. 19. Anchonus granulatus, sp.n. (Tab. V. figg. 22, 22a, ¢.) Oblong-ovate, black, the antenne and tarsi obscurely rufescent; the sets long and coarse, and arranged in fascicles on the more elevated portions of the prothorax and elytra. Rostrum (¢) stout, cylindrical, curved, coarsely seriate-punctate, not carinate, (Q) less coarsely punctate towards the tip, which is shining. Prothorax about as long as broad, somewhat rounded at the sides, narrowing and strongly constricted in front and narrowing behind; the surface, except along a narrow, flattened, smooth space down the middle and a narrow, irregular, sinuous space midway between it and the margin, closely set with small, smooth, shining tubercles, and more or less distinctly binodose and fasciculate at the apex, and sometimes on the middle of the disc also; the flanks very coarsely punctate. Elytra oblong-ovate, wider at the base than the prothorax, somewhat flattened on the disc and abruptly declivous at the apex ; very coarsely seriate-punctate, the interstices 2-6 uneven, and here and there minutely granulate, each with a series of oblong, prominent, setigerous tubercles, these forming carine at the base of 3 and 5, the tubercle on 3 at the commencement of the apical declivity larger than the rest, this interstice being interruptedly raised thence to the apex. Beneath sparsely punctured. Femora coarsely punctate. Length 54-63, breadth 23-3 millim. (¢ @.) Hab. Mexico, Toxpam (Sallé), Jalapa (Hége). Five specimens. This is one of several very closely allied Mexican forms, and amongst these it may be identified by the coarsely granulated prothorax (a character separating the species from all the other Central-American Anchont known to me), the unusually large tubercle on the third interstice at the commencement of the apical declivity, and the long, coarse setosity. As in A. elongatus, the sexual difference in the form of the rostrum is not very pronounced. 20. Anchonus salebrosus, sp. n. (Tab. V. fig. 23, ¢.) Oblong-ovate, black, the antenne and tarsi obscurely rufescent, the surface usually thickly covered with an earthy incrustation; the sete short, erect, and rather coarse. Rostrum stout, curved, cylindrical, feebly constricted at the base, coarsely seriate-punctate, the interspaces longitudinally wrinkled, the apical portion in the 2 shining, closely and more finely punctate. Prothorax about as long as broad, rounded at the sides, constricted and narrowed in front and narrowed behind ; the surface, except down a narrow median space and along a narrow sinuous space midway between this and the margin, coarsely, irregularly punctate, with the interspaces here and there raised and granulate, more or less distinctly binodose at the apex. lytra oblong-ovate, at the base slightly wider than the prothorax ; coarsely seriate-punctate, the interstices uneven and sparsely, minutely granulate, 2-7 each with a series of conical setigerous tubercles, these here and there united, forming short carine at the base of 3 and 5 and elsewhere on the disc, the elevations on the apical declivity subequal in size.

Very like A. granulatus, and perhaps nothing more than an extreme form of it, but differing from that species in the finely granulated, coarsely punctured prothorax, the more uniform size of the elevations on the third elytral interstice towards the apex, and the shorter setosity. ‘There is a good deal of variation in the development of the tubercles on the elytra, these being mostly conical in shape and coalescing on the disc into short ridges. 21.

Rostrum stout, cylindrical, curved, closely and rugosely punctured to the tip, the interspaces irregularly, longitudinally wrinkled, the widened apical portion short and dull in the ¢ and a little longer, shining, and parallel- sided in the 2. Prothorax distinctly flattened on the disc, slightly broader than long, rounded at the sides, constricted and narrowed in front and narrowed behind; the surface coarsely, closely, irregularly punctate, with the interspaces here and there raised and shining, shallowly sulcate down the middle, more or less distinctly binodose at the apex, on the middle of the disc, and at the sides. Elytra oblong-ovate, more or less flattened on the disc and abruptly declivous at the apex, at the base wider than the prothorax; coarsely seriate-punctate, the interstices 2-7 uneven, and here and there minutely granulate, each with a series of oblong or rounded, moderately prominent, setigerous tubercles, these forming a carina at the base of 3 and 5, 2 with the larger tubercle at the commencement and middle of the apical declivity sub- equal in size.

We have received one of Sallé’s specimens of this insect from the Dresden Museum, labelled with the MS. name of A. salle, Faust. Compared with its Mexican allies, the present species may be known by the extremely short setosity of the upper surface, the coarsely, irregularly, somewhat confluently punctured prothorax, and the more or less flattened disc of the elytra, the latter with moderately prominent tubercles, the larger ones at the commencement and middle of the apical declivity being subequal in size. The single (2) specimen from Jalapa has the elytra more flattened on the disc, and the tubercles on this portion of the surface less raised, forming inter- rupted caring. 99. Anchonus elongatus. (Tab. V. figg. 25, 25a, 2.) Anchonus elongatus, Fahy. in Schénh. Gen. Cure. vii. 2, p. 397°. Anchonus pedestris, Faust, Deutsche ent. Zeit. 1892, p. 49°. Hab. Mexico ? (coll. Chevrolat*), Toxpam (Sallé). I am unable to separate A. pedestris from A. elongatus, the type or co-types of which are before me, as well as a specimen from the Sallé collection. The setosity of the upper surface is extremely short, showing no tendency to form fascicles on the pro- thorax. In the type of A. elongatus the tubercles on the elytra form a conspicuous 80 RHYNCHOPHORA. ridge at the base of the third and fifth interstices, and the elytra themselves area little more elongate than in the two other examples seen. The eighth joint of the funiculus is transverse, and a good deal wider than the seventh. From dA. sal/@i it may be distinguished by its more elongate shape, the relatively longer prothorax, and the somewhat numerous tubercles on the second elytral interstice towards the apex, these being subequal in size. ahreus’s type is figured. 23. Anchonus oblongus, sp. n. (Tab. V. fig. 26, 26 a, 2.) Oblong-ovate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the sete coarse, rather short, and scattered. Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted, closely punctate throughout, the punctuation coarse, but becoming finer at the tip. Prothorax a little broader than long, somewhat flattened on the disc, widest at the middle, gradually narrowing thence to the base, and narrowing and constricted in front; the surface coarsely, closely punctate, except along a narrow, smooth, somewhat convex space down the middle and on an irregular sinuous flattened space midway between this and the margin, the interspaces between the punctures dull and here and there obliquely or sinuously raised, in one specimen faintly granulate, the sete showing a tendency to form two fascicles at the apex and two on the middle of the disc. Elytra oblong-ovate, convex, of the same width at the base as the prothorax ; coarsely seriate-punctate, the interstices 2-7 each with a series of oblong or rounded setigerous tubercles, those at the base of 3 and 5 cariniform, the suture also tuberculate beyond the middle. Femora coarsely rugosely punctate. Length 5-54, breadth 2-24 millim. (@.) Hab. Guatemaua, Capetillo (Champion). Two specimens, one in perfectly clean condition. Very like A. penictllatus, but more elongate, the prothorax coarsely, closely punctate, except down the middle and along a narrow space on either side of it (instead of being sparsely granulate), the sete much shorter, and not forming conspicuous fascicles on the prothorax. ‘The narrower and more elongate form, the irregularly punctured prothorax, the sides of which are less rounded and the disc without prominent fascicles, and the slightly constricted, closely punctured rostrum separate this species from A. cirratus(?). A specimen ( ¢ ) from San Gerénimo may also belong here ; but it has longer sete, and the elytra are here and there minutely granulate, both on the flattened and on the elevated portions of the surface. 24. Anchonus brevipennis, sp.n. (Tab. V. figg. 27, 27 4, 2 .) Obovate, black, the antennee and tarsi obscurely rufescent; the sete very short, but coarse, and arranged in © fascicles on the more elevated portions of the surface. Rostrum curved, stout, cylindrical, slightly constricted at the base, closely seriate-punctate, with the interspaces longitudinally wrinkled, the apical portion densely punctured in both sexes. Prothorax about as long as broad, rounded at the sides, narrowed and constricted in front and narrowed behind; the surface uneven, closely, coarsely punctate, shallowly suleate down the middle, and binodose at the apex and on the middle of the disc. Elytra convex, ovate, comparatively short ; seriate-punctate, the interstices 2-6 each with a scattered series of prominent, oblong, setigerous tubercles, 7 with small conical elevations. Length 4-43, breadth 2-21, millim. (¢ 2.) Hab. Mexico (Sal/é). ANCHONUS. 81 Two specimens. Very like A. verrucosus, but with the rostrum less constricted at the base, the prothorax not tuberculate at the sides, the prominences on the disc of the elytra stouter and less conical in shape. Larger, broader, and more robust than A. spiculosus, with the rostrum distinctly constricted at the base, the prothorax quadrinodose, and the elytra with stouter setigerous prominences. 25. Anchonus spiculosus, sp.n. (Tab. V. figg. 28, 28a, 2.) Oblong-ovate, black, the antenne and tarsi rufescent ; the sete very short, scattered, fine, and inconspicuous. Rostrum stout, cylindrical, strongly curved, rugosely punctured, smoother at the tip. Prothorax a little longer than broad, widest at the middle and narrowing thence to the base and apex, and constricted in front; the surface uneven, shining, coarsely, rugosely punctate, the interspaces here and there raised and granulate. Elytra convex, ovate; coarsely seriate-punctate, the interstices 2-7 each with a series of smooth, shining, conical tubercles, those on 2-5 intermixed with smooth oblong elevations. Femora _ coarsely punctate. Length 37, breadth 14 millim. (9.) Hab. Mexico (Sallé). One specimen, not labelled with any definite locality. A very small isolated form, distinguishable by the rugosely punctate, shining prothorax, the smooth, conical or oblong tubercles on the elytra, and the short, fine, inconspicuous sete. 26.

Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted, coarsely punctate, the punctuation becoming fine at the tip. Prothorax nearly as long as broad, widest a little before the middle, obliquely narrowing thence to the base, and narrowing and constricted imme- diately before the apex; the surface irregularly punctate and granulate, except along a narrow space down the middle, and with two small shining nodules at the apex, two in a line with them on the middle of the disc, and some others near the anterior angles, and two larger and more prominent elevations at the sides before the middle ; the flanks closely punctate. Elytra ovate, convex ; seriate-punctate, the interstices 1-7 each with a scattered series of shining, conical tubercles, which are here and there placed close together, so as to form short ridges. Length 43, breadth 2 millim. (2.) Hab. Guatemaa, Senahu in Vera Paz (Champion). One specimen. The chief characters of this insect are the two smooth, prominent tubercles on each side of the prothorax before the middle (the margins appearing strongly sinuate), and the four smooth, minute, nodiform elevations on its disc, the elytral interstices 1-7 each with a series of smooth, conical tubercles, which are here and there contiguous. The non-carinate, non-tuberculate rostrum separates it from A. verrucosus and A. tuderculirostris; and the basally constricted rostrum, different prothoracic sculpture, &c., from A. spiculosus, near which the species seems best placed.

Prothorax transverse, emarginate at the apex, slightly rounded at the sides, narrowed and constricted in front and narrowed behind; the surface coarsely, closely punctate, with the narrow interspaces here and there raised and shining. Elytra oblong-ovate, scarcely wider than the prothorax at the base; seriate- punctate, the interstices 2-7 (viewed laterally) interruptedly convex, and with scattered, smooth, granular elevations. Length 54, breadth 24 millim. (¢.) Hab. Costa Rica}, San José, 11385 metres (Biolley). In its basally constricted rostrum this species approaches dA. panamensis, Faust, from which it differs in its more oblong shape, the less constricted prothorax, and very dissimilar elytral sculpture. Dr. Heller has been kind enough to compare the single specimen received by us with the type in the Dresden Museum. ANCHONUS. 89 46. Anchonus foveifrons, sp. n. (Tab. VI. figg. 16, 16a, 6, 3.) Oblong, convex, shining, black, the antenne and tarsi obscurely rufescent; the sete short, erect, and numerous. Rostrum stout, curved, slightly thickened towards the base, and there a little constricted, densely, rugosely punctate to the tip, and faintly carinate anteriorly ; front very deeply foveate on each side at the base of the rostrum above; antennz inserted near the apex of the rostrum, the scape not reaching the eye. Prothorax broader than long, convex, a little flattened on the disc, fully as wide as the elytra, the sides strongly, arcuately dilated before the middle, rapidly converging towards the base, and converging and constricted in front; coarsely rugose, the ruge partly confluent and radiating obliquely forwards from the centre of the disc. Elytra convex, oblong-oval, of the same width as the prothorax at the base ; seriate-punctate, the interstices 2-7 tuberculate and granulate, the tubercles here and there coalescent and forming short ridges, the suture granulate throughout, Femora granulate. Length 5, breadth 24 millim. (¢.) Hab. Guatemata, Zapote, Pacific slope (Champion). One specimen, in very clean condition. A remarkable species, recognizable by the deeply bifoveate front of the head, the comparatively short antenne, the arcuately dilated, shining, closely rugose prothorax, and the peculiar elytral sculpture. The following species are unknown to me :— 47, Anchonus fraterculus. Anchonus fraterculus, Faust, Deutsche ent. Zeit. 1892, pp. 26, 45 (?)*. Hab. Costa Rica !. This insect, which appears to be very nearly related to A. murcidus, is described as oblong, convex, with the rostrum thickened towards the base, and then constricted ; the prothorax as broad as long, rounded at the sides, varioloso-punctate, and impressed down the middle; the elytra broader at the base than the prothorax, with the outer angles rectangular, coarsely seriate-punctate, the interstices here and there inter- ruptedly convex, sparsely granulate, and shortly setose.

Convex ; the prothorax subtransverse, strongly constricted near the apex and then abruptly dilated, a little narrowed towards the base, the surface setulose, densely, deeply punctate, with a slightly elevated median line; the elytra elliptic, remotely seriate-punctate, the dorsal interstices subcarinate, the alternate ones more raised towards the base, granulate and setose, the suture elevated, but not granulate. Length 5 millim.? RHYPARONOTUS. Rhyparonotus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 33. Ten species of this genus have been described, all from Colombia and Venezuela, one only of which (&. scapha) is known to me by name. They appear to be rare insects, the three forms now added from Costa Rica or Nicaragua being represented in our collection by seven specimens. Ahyparonotus is closely allied to Anchonus, but differs from it in having the anterior coxe separated, and from Cestophorus in the relatively shorter scape to the antenne. The funiculus is 8-jointed, the eighth joint large and closely articulated to the club. The scrobes are shallow behind. ‘The eyes are flattened and almost smooth, and not easily seen. §1. Rostrum not constricted at the base. 1. Rhyparonotus serripes, sp.n. (Tab. VI. fig. 17, ¢.) Elongate-ovate, black, the antenne and tarsi partly rufescent, the surface coated with an earthy incrustation ; the sete very short. Rostrum not constricted at the base, curved, a little shorter than the prothorax, granulate, rugusely punctured to the tip, obsoletely, longitudinally sulcate; scape reaching the anterior margin of the eye. Prothorax considerably longer than broad, somewhat rounded at the sides, gradually widening from the base to before the middle, and then narrowed to the apex and feebly constricted ; the surface granulate, except down the middle and along a sinuous space midway between this and the margin. LElytra about twice as long as the prothorax, oblong-oval, flattened on the disc, abruptly declivous behind, conjointly rounded at the apex ; seriate-punctate, the interstices 3, 5, and 7 (2, 4, 6 on the apical declivity) interruptedly costate, each with a scattered series of rounded, setigerous tubercles, which become more raised towards the tip, the tubercles smooth and shining at the summit. Ventral segments 1, 2, and 5, and the metasternum also, coarsely rugose. Legs rough, the femora granulate, the anterior and intermediate tibie sharply, and the posterior pair more finely, denticulate within. Anterior cox rather widely separated. Length 74-94, breadth 3-35 millim. (d¢.) Hab. Costa Rica, Caché, Volcan de Irazu (fogers). Three specimens, one of which is clean and immature. Separable from the following species by the non-constricted rostrum, the coarsely rugose under surface, the sharply denticulate inner edge of the tibie, &c. RHYPARONOTUS. 91 § 2. Rostrum constricted at the base. 2. Rhyparonotus vermiculatus, sp. n. Elongate-ovate, narrow, black, the antenne and tarsi obscurely rufescent, the surface coated with an earthy incrustation ; the sete extremely short, the femora with a few longer ones beneath. Rostrum strongly constricted at the base, stout, curved, nearly as long as the prothorax, rugosely punctured and shallowly, longitudinally sulcate; scape reaching the anterior margin of the eye. Prothorax much longer than broad, widest at the middle, more narrowed in front than behind, constricted before the apex ; the surface irregularly rugose, the rug: here and there confluent and forming sinuous or oblique ridges, and some- times shallowly grooved down the middle. Elytra oblong-oval, about twice as long as the prothorax, flattened on the disc, with the apex broadly produced and conjointly rounded (truncate as viewed from above), the humeri rather prominent, the basal margin raised ; coarsely seriate-punctate, the interstices 2 and 4 subcarinate, 5 and 6 also a little raised, 2,4, 6 each with a row of prominent, rounded, setigerous tubercles beyond the middle, the tubercles large on the apical declivity and represented by a scattered series of minute shining granules on the anterior half. Ventral surface very sparsely, finely punctate. Tibie finely denticulate on their inner edge. Anterior coxee somewhat widely separated. Length 74-8, breadth 24-3 millim. (<¢.) Hab. Costa Rica, Volcan de Irazu (Rogers), Volcan de Turrialba (Biolley). Three specimens. Distinguishable by its narrow form, the strongly constricted rostrum, the finely punctured ventral surface, and the extremely short sete of the upper surface. The prothorax in one example has the vermiculate sculpture interrupted at the middle by a narrow groove. 8. Rhyparonotus inermis, sp. n. (Tab. VI. fig. 18, 2.) Elongate-ovate, piceous, the surface coated with an earthy incrustation; the sete rather long and erect. Rostrum constricted at the base, very stout, strongly curved, about as long as the prothorax, granulate and trisulcate in its basal half and somewhat sparsely punctured at the tip ; scape reaching the anterior margin of the eye. Prothorax slightly longer than broad, gradually widening from the base to near the apex and then abruptly narrowed and constricted ; the surface, except down the middle and along a sinuous space on each side midway between this and the margin, sparsely granulate, with intermixed sinuous ruge. Elytra oval, about twice as long as the prothorax, sharply margined at the base, the apex broadly produced and conjointly rounded ; seriato-foveate, the interstices 2, 4, and 6 more or less costate, 2 sharply so on the apical declivity, each set with scattered rounded or oblong setigerous elevations, which become more numerous and very prominent towards the apex. Ventral surface very sparsely, finely punctate. Anterior cox rather narrowly separated. Tibie almost smooth on their inner edge. Length 73, breadth 3 millim. ( 9.) Hab. Nicaracua, Chontales (Belt). One specimen. Allied to FR. vermiculatus, but broader, with the rostrum more curved, the prothorax shorter, less rugose, and widest before the middle, the second elytral interstice much more raised towards the apex, the anterior coxe more approximate, the tibie not denticulate on their inner edge, the sete on the upper surface slightly longer.

Five species are known of this genus—one from Central America, three from San Esteban, Venezuela (two of which I have seen), and one from the Island of Guadeloupe. They are very like the narrower and more elongate Anchont, but are easily separable therefrom by the 6-jointed funiculus* to the antennew. The funiculus is short, gradually widening from the elongate second joint, joints 3-6 being transverse, and 6 almost as wide as the club, These insects are usually so coated with dirt that nothing can be seen of the sculpture till they have been cleaned. 1. Geobyrsa nodifera, (Tab. VI. figg. 19, 2 ; 19 @, antenna.) Geobyrsa nodifera, Pasc. Journ. Linn. Soc., Zool. xi. p. 450, t. 13. figg. 1, la, b*. Elongate-obovate, nigro-piceous, setose, the sete clubbed and forming fascicles on the prothorax and on the elytral tubercles. Rostrum curved, as long as the prothorax, coarsely seriate-punctate, the widened apical portion short in the ¢, and rather long and cylindrical in the 9. Prothorax subcylindrical, much longer than broad, a little narrowed in front and behind, slightly constricted before the middle, and emarginate in the centre at the base; the entire surface closely, deeply, and very coarsely punctate, the setee forming two fascicles at the apex and four in a transverse row about the middle. Elytra oblong- ovate, convex, closely and coarsely seriato-punctate, the interstices very narrow, the alternate ones each with a row of scattered setigerous tubercles. Length 4-5, breadth 14-2 millim. (¢ 9.) Hab. Guatemaua, El Tumbador (Champion); Nicaragua (Sallé), Chontales ! (Belt). Very like A. simoni, Faust, from Venezuela (a typical example of which is before me), but with the punctuation of the prothorax and elytra very coarse and foveiform, the prothorax without a smoother space down the middle, the setigerous tubercles on the elytra a little more prominent. Pascoe’s type is in a very dirty condition, and the puncturing of the surface was not noticed by him. Four specimens have been received by us. Sect. Il. Eyes placed at the sides of the rostrum. DIOPTROPHORUS. Dioptrophorus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 35. This remarkable genus is peculiar to Mexico, Guatemala, and Cubay. ‘The type, D. ocularis, was included by Boheman in Anchonus, though he noticed that the coarsely facetted eyes were placed at the sides of the rostrum, instead of on the smooth globular portion of the head, as in Anchonus and its allies. The males, as in * Described by Pascoe as ? 5-jointed, and by Faust as 7-jointed. + In the British Museum there is a Dioptrophorus from Cuba, labelled with the MS. name Anchonus angusticolls, Chevr. DIOPTROPHORUS. . 98 Anchonus, differ from the females in having the antenne inserted nearer the tip of the rostrum, with the apical portion of the latter somewhat rounded at the sides. In D. verrucosus, which is larger and more robust than any of its allies, the facets of the eyes are flattened, while in the other species they are convex. § 1. Hye-facets convex. 1. Dioptrophorus ocularis. Anchonus ocularis, Fahr. in Schénh. Gen, Cure. vii. 2, p. 894". Dioptrophorus ocularis, Faust, Deutsche ent. Zeit. 1892, p. 35”. Hab. Mexico ? (coll. Sommer '). Not seen by Faust, nor contained in our collection, the numerous specimens received under this name from Sallé being incorrectly identified, and belonging to the genus Anchonus. D. ocularis, to judge from the description, must be very nearly allied to D. simplex, but with the prothorax widening from the base to before the middle and then suddenly narrowed ; it is not unlikely that they will prove to belong to the same species. 2. Dioptrophorus simplex. Dioptrophorus simplex, Faust, Deutsche ent. Zeit. 1892, pp. 36, 59°. Hab. MeExico', Jacale (Sallé), Toluca, Cordova (Hége). Apparently not rare in Mexico, whence upwards of a dozen examples have been received by us. In one or two of them the elytral elevations are fewer in number and less distinct, and in others they are more elongate. Length 4-5 millim. 3. Dioptrophorus fausti, sp. n. (Tab. VI. figg. 20, 204, 3.) Elongate-ovate, rather depressed, black, the legs piceous, the antennz obscurely rufescent ; covered in part by a greyish incrustation and with scattered minute ochreous scales, the legs with short hairs. Rostrum stout, nearly as long as the prothorax, coarsely, very shallowly punctate. Prothorax a little longer than broad, widest at the middle, narrowed anteriorly and slightly so posteriorly, constricted before the apex, the hind angles somewhat obtuse; coarsely punctate, except along a depressed space down the middle and a sinuous space on each side between this and the margin. Elytra nearly twice as long as the prothorax, flattened on the disc to near the apex and then abruptly declivous ; coarsely seriato-punctate, the alternate interstices with scattered, feeble, oblong elevations, the third and fifth each with a very prominent tubercle at the commencement of the apical declivity. Length 5, breadth 2), millim. (¢.) Hab. Mexico (Sal/é). One specimen. Very like D. simplex, but more depressed, the elytra each with two very prominent tubercles at the commencement of the apical declivity, a character also shared by D. prolixus. 94 RHYNCHOPHORA. 4. Dioptrophorus prolixus, sp. n. (Tab. VI. fig. 21, 2 .) Elongate, black, the antenne and the tips of the tarsi obscurely rufescent ; covered with a greyish incrustation and with scattered minute narrow ochreous scales, the legs with short hairs. Rostrum about as long as the prothorax, coarsely, but shallowly punctate ; antenne inserted at about one-third from the apex of the rostrum. Prothorax longer than broad, widest at the middle, narrowing anteriorly and slightly so posteriorly, strongly constricted before the apex, the hind angles subrectangular; the surface uneven, coarsely, irregularly punctate, and with six prominent tubercles—two at the apex, two on the middle of the disc, and one on each side before the middle. Elytra more than twice the length of the prothorax, flattened on the disc for fully three-fourths of their length and then abruptly declivous to the apex ; eoarsely seriate-punctate, and with rows of oblong or rounded tubercles extending from the base to the apical declivity, the last two on each elytron being large and very prominent, those on the apical portion cariniform and inconspicuous. Length 7, breadth 3 millim. (2.) Hab. GuaTEMALA, Totonicapam between 8500 and 10,500 feet (Champion). Differs from its allies in its larger size and much more elongate shape, the series of conspicuous elevations on the elytra culminating in four very prominent rounded tubercles before the abruptly sloping apical declivity. ‘The single specimen obtained appears to be a female; and, if so, the antenne are inserted a little nearer the apex than usual. 5. Dioptrophorus sharpi. (Tab. VI. figg. 22, ¢ ; 23, 2.) Dioptrophorus sharpi, Faust, Deutsche ent. Zeit. 1892, pp. 36, 58°. Hab. Guatemata 1, Totonicapam 8500 to 10,500 feet (Champion). Found in profusion under the bark of pines at Totonicapam. This insect is very like D. simplex, but differs from it in having the prothorax more uneven on the disc, and the sides straighter behind, the posterior angles being subrectangular. Length 4-54 millim. 6. Dioptrophorus fahrei. (Tab. VI. fige. 24, 24a, 9.) Dioptrophorus fahrei, Faust, Deutsche ent. Zeit. 1892, pp. 86, 59°. Hab, GuatemAta}, Totonicapam 8500 to 10,500 feet (Champion). If I have identified it correctly, three specimens only of this species are contained in our collection. They are narrower than D. sharpi, with the prothorax a little longer, more uneven, and constricted nearer the apex, so as to appear wider anteriorly, and the elytral elevations more elongate. Length (3 2?) 42-5 millim. § 2. Eye-facets flattened. 7. Dioptrophorus verruciger, sp. n. (Tab. VI. figg. 25, 25 a.) Elongate-ovate, robust, black, coated in great part with an earthy incrustation ; the setosity extremely short. Rostrum very stout, shorter than the prothorax, constricted at the base, coarsely, closely punctate, and obsoletely carinate down the middle; eyes comparatively large, not very prominent, the facets flattened. DIOPTROPHORUS.—ITHAURA. 95 Prothorax much longer than broad, widest a little before the middle and obliquely narrowing thence to the base and apex, constricted in front, the apex emarginate; the disc somewhat flattened, irregularly carinate down the middle, and with a large, depressed, subtriangular space on either side towards the apex, the depression followed by two angular prominences, the rest of the surface with coarse scattered punctures and irregular ruge, the margins subtuberculate at the middle. Elytra oblong-ovate, much wider than the prothorax, but at the base of nearly the same width, considerably produced at the apex ; interruptedly seriate-punctate, the interstices with a scattered series of large, rounded, exceedingly prominent tubercles, these becoming more elongate towards the base and there forming ridges on the third and fifth. Legs stout. ‘Length 9, breadth 4 millim. (?9.) Hab. Mexico, Sierra de Durango (Flohr). One specimen. Larger, more robust, and more elongate than any of the other known species of the genus, the elytra strongly nodose, the eye-facets flattened, instead of convex. In general facies D. verruciger is very like Anchonus nodosus. ITHAURA. Ithaura, Pascoe, Journ. Linn. Soc., Zool. ix. p. 215, t. 6. figg. 2-2 a-c (1871) ; Ann. & Mag. Nat. Hist. (5) vu. p. 808 (1681). Head globose, smooth; rostrum constricted at the base, stout, feebly curved, the apical portion a little widened, the scrobes deep, visible from above anteriorly, descending to beneath the eyes, and some- what widely separated behind; eyes rounded, coarsely facetted, placed at the sides of the rostrum behind: antenne inserted at about one-third from the apex of the rostrum, the funiculus 7-jointed, joints 1 and 2 subequal in length, the others transverse, the scape reaching to about the middle of the eyes, the club short-ovate and pubescent; buccal opening large, the oral organs visible; prosternum much developed in front of the anterior coxe, slightly hollowed at the apex, with a transverse sulcus near the anterior margin; pronotum extending backward over the mesonotum; anterior coxe very narrowly separated; mesosternum extending forward in front of the intermediate cox, which are narrowly separated; scutellum wanting; elytra connate, hollowed at the base, with the subangular humeri embracing the hind angles of the prothorax, covering the apex of the abdomen, and without membranous apical margin ; first and second ventral segments connate at the middle, the third and fourth short, the sutures 2 and 3 deep and straight ; femora stout; tibie mucronate at the inner apical angle, the anterior pair sharply so, and with a terminal claw arising from about the middle of the apical margin ; third tarsal joint a little widened, entire at the apex, the fourth joint articulated to it in a cavity on the upperside; claws slender, simple, divergent; body elongate-oval, apterous, coated with a hard permanent, glossy incrustation. This remarkable genus was referred by Pascoe somewhat doubtfully to the Calandrine, but it seems to me to be very closely related to Dioptrophorus, of the group Anchonina. The two species described by him were from Colombia and Parana respectively, and two others are now added from our region. Typhlo- glynma, Dury *, also referred to the Calandrine by its describer, including a single N.-American species, is a nearly allied form. The above-mentioned characters, taken from the Central-American insects, will supplement Pascoe’s description. In Ithaura there are well-developed eyes at the sides of the rostrum (as in Dioptrophorus and Theognete), the scrobes are somewhat distant beneath, the first * Journ. Cincinnati Soc. Nat. Hist. xix. pp. 243, 244, fig. (March 1901), 96 RHYNCHOPHORA‘ and second ventral segments are separated laterally, and there is no visible scutellum* ; whereas in Typhloglymma the eyes are stated to be wanting, the scrobes are subcon- tiguous beneath, the first and second ventral segments are completely fused, and there is a small visible scutellum. From Dioptrophorus the present genus differs in having the prosternum more developed in front of the anterior coxe, the pronotum extending back over the mesonotum (the elytra being hollowed at the base for its reception), &c. ; the entire surface, too, is coated with a permanent, smooth, glossy incrustation. The two species here described were found at a high elevation in Guatemala and Mexico respectively, one of them under the bark of fallen pines. The unique type of Typhlo- glymma was taken out of debris from a cavity in a decayed oak, in which was a nest of Formica pennsylvanica. 1. Ithaura pinicola, sp.n. (Tab. VI. figg. 26, 26a, 3; 27, 9.) Moderately convex, grey or brownish-grey, the antenne and tarsi obscurely rufescent ; the upper surface very coarsely and somewhat closely punctate, with the interspaces smooth, the punctures each bearing one or two extremely minute golden scales ; the legs with a few short hairs, and some longer and more bristly ones on the lower edge of the femora and on the inner edge of the tibie. Rostrum strongly constricted at the base, much shorter than the prothorax in both sexes, smoother in the Q than in the g. Prothorax longer than broad, feebly rounded at the sides, narrowed in front and slightly so behind, strongly constricted at the sides before the apex, the groove not extending across the dorsal surface, the disc finely carinate down the middle; the punctures large and rounded. Elytra oblong-oval, a little wider and nearly one-half longer than the prothorax, conjointly rounded at the apex ; the punctures large, oval, and arranged in nine regular rows ; the interstices flat in some specimens and distinctly convex in others. Beneath very coarsely punctate, except the third and fourth ventral segments, which are smooth, the first segment flattened in the middle in the ¢. Tibie very minutely denticulate on the inner edge ; the anterior pair with a fine sharp tooth before the middle in the ¢. Length 43-6, breadth 2-2} millim. (¢ @.) Hab. Guatemata, Totonicapam 8,500-10,500 feet (Champvon). Ten specimens, found under the bark of decaying pines. The sculpture of the upper surface of this species is exactly like that of Typhloglymma puteolatum, from Ohio, as figured by Dury. The much smaller size, the very coarsely punctured thorax, &c., separate it from J. strangulata, the type of the genus. 2. Ithaura exarata, sp.n. (Tab. VI. fig. 28, 3.) Elongate-ovate, convex, greyish-olivaceous, the antenne and tarsi rufescent ; the punctures of the upper and under surfaces each bearing a minute, piliform, golden scale ; the legs with short hairs. Rostrum feebly constricted at the base, a little more than one-half the length of the prothorax, coarsely, closely punctate. Prothorax longer than broad, distinctly rounded at the sides, narrower in front than at the base, the anterior constriction just visible from above ; the surface somewhat closely impressed with large rounded punctures separated by smooth, flat interspaces, and with indications of a raised line down the middle. Elytra oval, nearly one-half longer than the prothorax, finely seriate-punctate, the interstices strongly convex, of the same width as the spaces between them, and each with a series of very fine scattered punctures. Beneath extremely coarsely punctate, except the anterior portion of the mesosternum and the third and fourth ventral segments, which are smooth, the first segment flattened in the middle. Length 54, breadth 24 millim. (<¢.) * Pascoe states that there is a small scutellum present; but this is a mistake, as shown by his figure. ITHAURA.—THEOGNETE. . 97 Hab. Mexico, San Antonio de Arriba (Salié). One specimen. Differs from J. pinicola in the more convex shape, the feebly constricted, shorter rostrum, and the sulcate, finely seriate-punctate elytra. The anterior tibia are without a median tooth. THEOGNETE, gen. nov. Antenne with the funiculus 7-jointed, joints 3-7 transverse and gradually widening, 7 closely articulated to the club, the latter short-ovate, pointed at the tip, the first joint shining and the others dull and pubescent; head globose, smooth; rostrum stout, constricted at the base, slightly widened in its apical half, the scrobes deep, lateral, descending to beneath the eyes, the anterior opening just visible from above; the eyes placed at the sides of the rostrum behind, oval, coarsely facetted ; prothorax trans- versely convex, with a transverse sulcus before the anterior margin beneath, visible at the sides above, the prosternum very short; anterior cox somewhat widely separated; intermediate coxe widely separated, the mesosternum transversely sulcate between them; metasternum extremely short; posterior cox inserted near the outer margin of the body, and narrowly separated from the intermediate pair; scutelium absent ; elytra connate, gibbous, cordiform ; ventral segments 1, 2, and 5 subequal in length, 3 and 4 exceedingly short, 1 and 2 connate, the first suture sinuous; legs short and stout; tibie slightly sinuate within, not dilated at the tip, mucronate at the inner apical angle, and armed with a curved claw at the apex, the lower apical margin furnished with several fine tecth ; tarsi very short, feebly developed, sparsely pilose beneath, the third joint bilobed, the claws extremely minute, free. The single species referred to this genus has somewhat the facies of a Liosomus or a minute Liparus. It is a very remarkable form, wholly different in appearance from Dioptrophorus, to which Theognete is nearly related. ‘The tarsi are very small and short, compared with the powerful femora and tibie. ‘The anterior coxe are a little more widely separated than in any of its nearest allies. 1. Theognete levis, sp.n. (Tab. VI. figg. 29, 29 a, 6.) Obovate, very convex, shining, black, the tarsi and the antenne in part rufescent; the prothorax and elytra with a few, widely scattered, appressed, long, coarse, piliform, flavescent scales ; the legs with similarly- coloured short hairs. Rostrum nearly as long as the prothorax, coarsely and closely punctured ; the -antenne inserted at about the middle. Prothorax as long as broad, constricted at the apex and narrowed ‘behind, the sides slightly sinuous in one specimen; the surface smooth, with minute scattered squami- gerous punctures. Elytra short, gibbous, with the apices produced and conjointly rounded, about one-half longer, and much wider than the prothorax, smooth, each with a longitudinal groove near the suture below the base, in which traces of seriate punctures are visible. Beneath smooth. Fifth ventral segment obliquely sloping from about the middle to the apex, the anterior portion flattened and with a_ transverse-oval depression in the. middle, the posterior portion with a transverse depression on each side in front and another in the centre behind. Length 3, breadth 13 millim. Hab. Mexico, Sierra de Durango (Flohr) ; Guaremata, Cerro Zunil (Champion). One specimen from each locality, their sex not ascertained. The Mexican individual is a little more robust, and has stouter legs, and coarser scattered scales, than the Guatemalan insect. BIOL. CENTR.-AMER., Coleopt., Vol. IV.

The type ef this insect, which is not labelled with any definite locality, is contained in our collection, and we have six others from Hoge or Sallé. C. fossus is probably nothing more than a southern form of C. pulvereus, Lec.; but may be separated by its more robust build, stouter rostrum, and coarser sculpture. The largest specimens, including the type, are considerably broader than any of the numerous North-American or Mexican C. pulvereus before me. The rostrum is sometimes obsoletely carinate. 2.

Subovate, convex, robust, rather shining, black, thickly clothed with cinereous pubescence ;. the prothorax with the apex and a broad space down the middle, and the elytra each with two fascize on the disc, almost glabrous. Rostrum short, very stout, dilated at the tip, flattened above, coarsely punctured, with the interspaces densely, minutely punctate, obsoletely carinate. Prothorax broader than long, the sides (as seen from above) subparallel from the base to near the apex, and then abruptly and obliquely converging; the surface uneven, coarsely, irregularly punctured, with the interspaces densely, minutely punctate; the anterior margin simply sinuate opposite the eyes, the vibrissee long. Elytra moderately long, oval, widest about the middle ; coarsely seriate-punctate, the interstices narrow, almost smooth. 3, 5 and 7 costate, 5 not callose towards the apex. Beneath somewhat coarsely punctate; ventral segments 1 and 2 broadly depressed down the middle. Tarsi with small spongy-pubescent pads beneath ; claws free. Length 83-94, breadth 4-43 millim. (¢.) Hab. Mexico, Refugio in Durango (Hége), Sierra de Durango (Lohr). Two specimens. This insect differs from the other Mexican forms in having the tarsal claws free and the alternate elytral interstices costate.

Elongate-ovate, moderately robust, somewhat shining, black, the minute spines along the apical margin of the tibiee ochreous ; above somewhat sparingly clothed with cinereous pubescence, which does not hide the punctures, and is here and there variegated with whitish, and denuded in places, so as to give a mottled appearance to the elytra, the prothorax with a sinuous whitish vitta on each side (leaving a broad, sharply defined, partially denuded, dark space down the middle of the disc); the under surface and legs somewhat densely clothed with whitish pubescence, with small, scattered, partially denuded spots, these becoming larger and more conspicuous on the first four ventral segments. Rostrum very stout, widened at the tip, coarsely punctate, the interspaces closely and minutely punctured, not carinate; second joint of the funiculus much shorter than the first and longer than the third. Prothorax (along the median line) about as long as broad, conspicuously tuberculate at the sides a little before the apex, so as to appear abruptly narrowed and constricted in front, the sides almost straight from the tubercle to the base; the surface uneven, strongly depressed in the middle at the base, irregularly foveato-punctate, the interspaces closely, minutely punctate; the anterior margin simply sinuate opposite the eyes and furnished with long vibrisse. Elytra elongate, much wider than the prothorax, a little rounded at the sides along the median third, subparallel towards the base, the apices considerably produced, the humeri rounded ; seriate- punctate, the punctures here and there larger and foveiform, the interspaces flat, rugulose, and each with a scattered series of minute granules. Prosternum with the tubercle in front of each anterior coxa small, completely covered by the white pubescence. Length 14, breadth 53 millim. ( 2.) Tab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn). One specimen. In Captain Casey’s arrangement of the species (Ann. N. York Acad. Sci. vi. pp. 177, 178), this species would fall under his second group, from all the members of which it differs in the sparser and more mottled vestiture of the upper surface (which is not dense enough to hide the larger punctures) and the conspicuous denuded spots on the ventral surface.

Scaphomorphus, Motschulsky, Bull. Acad. St. Pétersb. ii. p. 541 (1860). A genus of almost universal distribution. In nine out of the twenty-three species * here enumerated from within our limits, the wings are rudimentary or absent, the elytra being particularly hard in these forms. ‘They all have the scutellum vertical or depressed, and often quite invisible when the prothorax is closed up to the elytra ; and the eyes oval in shape. J. basilaris, L. mexicanus, &c., vary enormously in size, with a corresponding variation in the development of the rostrum, which is almost always longer in the female than in the male (very much longer in L. fimbriolatus and L. toltecus), and antenne, the latter being usually inserted nearer the tip of the rostrum in the males. The sculpture, too, is somewhat unstable, as is also the relative length of the basal joints of the funiculus and the prolongation or otherwise of the apices of the elytra. The members of this genus, as is well known, are often coated with a dense pollinose secretion, which is said to be renewable during the life of the insect ¢, completely covering the sculpture and pubescence: the amount of pubescence seems to be variable (at least in several of the species), some of that visible in fresh specimens being afterwards lost; and the presence of a condensed submarginal vitta, unless accompanied by a corresponding groove, is an inconstant character. ‘The males of most of the Central-American forms have the basal one or two segments of the abdomen more or less sulcate down the middle. No fewer than 233 species of Lirus are enumerated in the “Munich Catalogue,” but a number of these names must be synonyms.

Brit.), Atenas (Mus. Dresden); Panama, Bugaba, Volcan de Chiriqui, David, Taboga I. (Champion). Apparently the commonest species of the genus in Central America, and readily identified by the acutely dentate anterior femora and the comparatively short curved rostrum, which is a little longer in the female than in the male. The larger punctures on the prothorax and elytra are sometimes quite fine. A pair from Duefias are more thickly pubescent than the rest, but this is probably due to their fresh condition, the longer hairs being easily abraded; and two of the smallest females, from Chiriqui (perhaps specifically distinct), have the rostrum much more slender than usual and the LIXUS, 103 basal constriction of the elytra not apparent. About eighty specimens have been seen, varying greatly in size and in the amount of pubescence on the surface. Several South-American Liat have dentate femora, but our insect seems to be different from all those described *. | 2. Lixus cavicollis, sp. n. Lizxus cavicollis, Chevr. in litt. Elongate, robust, subfusiform, moderately shining, black, clothed with a very short, sparse, cinereous pubescence, which is often mottled on the elytra; the legs and under surface with intermixed longer hairs. Head excessively minutely punctate, with intermixed slightly coarser punctures, foveate between the eyes; rostrum shining, very stout, about as long as the prothorax in both sexes, longitudinally sulcate between the points of insertion of the antenna, the punctuation a little sparser than that of the head. Prothorax convex, conical, about as long as broad, strongly bisinuate at the base, the median lobe almost covering the vertical scutellum ; densely, minutely punctate, with scattered, intermixed, coarser punctures, the basal impression large, rounded, and very deep; anterior margin with a short obtuse tooth opposite the lower angle of the eyes. Elytra very elongate, much wider than the prothorax, abruptly and sinuously narrowed at the base and narrowing from the middle to the apex, the apices acutely produced, the common basal impression broad and deep, the anterior margin somewhat raised ; seriate-punctate, the interstices flat and minutely, rugulosely punctate. Beneath shining, sparsely, very minutely punctate, with intermixed coarser punctures. First and second ventral segments with a deep groove down the centre in the ¢. Body winged.

Brit.), San José (Biolley). L. cavicollis is quoted by Boheman as synonymous with Z. fimbriolatus, but it differs from that species in its broader and more robust form, the scantier pubescence (which is not all concentrated laterally), the very stout, comparatively short rostrum in both sexes, and the larger depression at the base of the prothorax. ‘This is a common insect in Mexico and Guatemala, whence we possess a long series, varying only in size. 3.

Yucatan (Gawmer); GUATEMALA, Las Mercedes; Duefias (Champion). In the typical form of this insect the prothorax and elytra have a submarginal vitta of condensed whitish pubescence, a character also to be found in certain specimens of L. macer (as noted by Leconte); but this is frequently obsolete, and in our series of twenty-eight examples from Mexico or Guatemala four only possess this peculiarity. L. fimbriolatus may be identified by the dissimilarity in the length of the rostrum in the two sexes, it being about twice the length of the prothorax and strongly curved in the female, and shorter and moderately curved in the male. The first and second ventral segments are more or less sulcate down the middle in the male. The rostrum is slightly widened at the tip. We are indebted to Mr. Wickham for specimens of L. macer from Ulinois and Iowa, with which our smallest examples agree. In s1X out of the seven males from Duefias the pubescence is longer and more abundant than usual, but this is probably due to their fresh condition. Length varying from 15-23 millim. 4. Lixus inermis, sp. n. Elongate, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, the pubescence in some specimens condensed into a narrow more or less distinct submarginal vitta. Head and rostrum closely, minutely punctate, with intermixed coarser punctures, the head foveate between the eyes; rostrum moderately stout, in the ¢ about as long as the prothorax and moderately curved, in the 9 slightly longer and strongly curved. Prothorax about as long as broad, subconical, strongly bisinuate at the base; densely, minutely punctate, with intermixed coarser punctures, the basal depression rounded and very deep. Elytra very little wider than the prothorax, subparallel for three-fourths of their length; more or less acuminate at the apex, the common basal depression broad and shallow ; seriate-punctate, the interstices flat and rugulosely punctate. First and second ventral segments shallowly sulcate down the middle in the g. Body winged. Length 103-15, breadth 3-4 millim. (d Q.) Hab. Mexico, Toxpam in Vera Cruz (Sallé). Seven specimens, three of which are immature. This species may be known from L. cavicollis by its narrower, cylindrical shape (the elytra being scarcely wider than the prothorax) and the more slender rostrum ; and from L. jimbriolatus by the shorter rostrum in both sexes, that of the female being very little Jonger than that of the male, as well as by its cylindrical form, smaller size, and less robust build. The unarmed anterior femora and the acuminate elytra separate L. inermis from L. dentipes, which is very like it in general facies; and the subparallel and less acuminate elytra from LL. subcaudatus. 5, Lixus rugulirostris, sp. n. Very elongate, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, in one specimen with a well-defined submarginal white vitta.

LIXUS. 105 Prothorax as long as or longer than broad, conical, densely, minutely punctate, with intermixed coarser punctures, the basal depression small and shallow. Elytra very elongate, a little wider than the prothorax, subparallel for three-fourths of their length, the apices slightly dehiscent and acuminate, the common basal depression shallow ; seriate-punctate, the interstices flat, finely rugulose. First ventral segment unimpressed. Body winged. Length 123-154, breadth 3-32 millim. ( 9.) Hab. Mexico, Puebla (Sallé), Amula (H. H. Smith). Three specimens, probably all females: the one from Amula has a white submarginal vitta, the prothorax longer than broad, and the rostrum sparsely punctured towards the tip; the two from Puebla, which are covered with efflorescence, have the rostrum densely rugulose to near the apex, and the elytra without trace of a submarginal vitta. They possess in common, however, a very shallow depression at the base of the pro- thorax, a character separating them from the nearly allied LZ. inermis. The rostrum is comparatively slender. " 6. Lixus toltecus, sp. n. Very elongate, narrow, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, the pubescence mottled on the elytra, and with a condensed whitish submarginal vitta on the prothorax and towards the apex of the elytra. Head shallowly foveate between the eyes, in the ¢ closely punctate, with coarser punctures intermixed, in the 2 sparsely punctured ; rostrum in the ¢ moderately stout, about as long as the prothorax, feebly curved, and closely, longitudinally rugulose almost to the tip, in the 2 slender, distinctly longer than the prothorax, strongly curved, sparsely punctured from the base to near the middle and almost smooth thence to the apex ; antenne in the ¢ inserted considerably before, and in the 2 a little behind, the middle of the rostrum, joint 2 of the funiculus slightly shorter than 1 in both sexes. Prothorax convex, rather broader than long, subconical, strongly bisinuate at the base ; closely, minutely punctate, with intermixed coarser punctures, the basal depression small and extending forward. Llytra very elongate, of the same width as the base of the prothorax, subparallel for two-thirds of their length, somewhat acuminate at the apex, the common basal depression shallow ; seriate-punctate, the interstices flat and finely rugulose. First ventral segment unimpressed in both sexes. Body winged. Length 93-11, breadth 23-25% millim. (¢ 2.) Hab. Mexico, Puebla (Sal/é), Atlixco in Puebla (Hége). Two males and two females. In this small species the sexual difference in the form of the rostrum is almost as strongly marked as in L. fimbriolatus, that of the female being slender, moderately long, strongly curved, and almost smooth beyond the middle. In general shape L. toltecus resembles L. nigrinus, which, however, is not a very nearly allied form. 7. Lixus subcaudatus. Lizus subcaudatus, Boh. in Schénh. Gen. Cure. vii. 1, p. 428°. Hab. Mexico!

In the two specimens ( ¢ ) from the Sturm collection the second joint of the funiculus is longer than the first, and this is the case in nearly all our other examples, including the six from Guatemala; the second joint, however, seems to vary in length in this species, irrespective of sex.

It has the prothorax broadly flattened or depressed on the disc, and the elytra flattened on the disc towards the base. The pubescence of the upper surface is cinereous, and slightly mottled in places, being sufficiently condensed at the sides of the prothorax to form vitte.

Very elongate, narrow, subcylindrical, shining, black or piceous, the antennz and tarsi reddish; clothed with rather long fulvo-cinereous pubescence, which is somewhat mottled on the elytra. Head foveate between the eyes, rugosely punctured; rostrum curved, comparatively slender, longitudinally rugose, in the © strongly curved and about as long as the prothorax, slightly shorter in the ¢; eyes convex, prominent; antenne inthe ¢ inserted before, and in the 2 at, the middle of the rostrum, joint 2 of the funiculus slightly shorter than 1. Prothorax longer than broad, narrowing from about the middle ; closely, rather coarsely punctate, with the narrow interspaces rugulose, obsoletely carinate from the base to before the middle, and also shallowly sulcate at the base. Elytra scarcely wider than the prothorax, subparallel in their basal half and gradually narrowing thence to the apex, the apices strongly caudate, the basal margin raised, projecting a little at the sides; deeply seriate-punctate, the interstices narrow, rugulose, and almost flat. Beneath finely punctate. First ventral segment unimpressed in both sexes. Legs slender. Body winged. Length 93, breadth 2 millim. (¢ 2.) Hab. GuatEMata, Duefias, Capetillo (Champion). Three specimens. In this and the following species the larger punctures of the prothorax are so closely placed that the minute interstitial punctuation is scarcely visible ; the rostrum is slender and rugose; the eyes are prominent; and the second joint of the funiculus is shorter than the first. The strongly caudate elytra, the more rugose rostrum in the female, &c., separate it from L. nigrinus. 14. Lixus nigrinus, sp. n. Livus nigrinus, Sturm, in litt. Very elongate, narrow, subcylindrical, shining, black, the antenne and tarsi more or less rufescent; finely cinereo-pubescent, the pubescence mottled on the elytra. Head rugosely punctured ; rostrum slender, curved, in the ¢ almost as long as the prothorax and rugose to near the tip, in the 9 a little longer and with the apical half much smoother ; eyes prominent; joint 2 of the funiculus slightly shorter than 1. Prothorax rather longer than broad, narrowing in front; closely, somewhat coarsely punctate, not or very feebly depressed at the base. Elytra scarcely wider than the prothorax, subparallel to about the middle, the basal margin raised, projecting a little laterally, the apices separately produced, the suture appearing to be emarginate at the tip; seriate-punctate, the interstices flat and finely rugulose. First ventral segment unimpressed in both sexes. Body winged. Length 63-11, breadth 14-21 millim. (¢ @.) Hab. Mexico (Sallé, ea coll. Sturm), Orizaba (Sallé), Almolonga, Acapulco (Hége), Temax in N. Yucatan (Gawmer); British Honpuras, Rio Hondo (Blancaneauz) ; GUATEMALA, San Gerdnimo, Duefias (Champion). LIXUS. 109 Sent in plenty from Yucatan. The smallest of the Central-American species, and differing from the preceding as noted above. ‘There is a specimen of it from Orizaba, labelled with the MS. name JL. tenuis, in the British Museum. § 2. Wings absent or rudimentary. 15. Lixus germari. (Tab. VII. figg. 8, 8a, 2.) Lixus germari, Boh. in Schénh. Gen. Cure. vii. 1, p. 455 *. Hab. Mexico}, Sierra de Durango, Teopisca, Motzorongo (Flohr), Toxpam (Sa/llé), Teapa (H. H. Smith). Not rare in North-western, Central, and Eastern Mexico. This species, which is broader and more convex in form than any of the other Central-American members of the genus, has the triangular scutellum* depressed almost to the level of the mesonotum (and only visible when the prothorax is separated from the elytra), and the wings are rudimentary. The elytra are here and there transversely depressed on the disc, and, when covered with efflorescence, bifasciate. The rostrum is very stout and strongly curved, and very little longer in the female than in the male. The first ventral segment is sulcate down the middle in the male.

There is a single female specimen of this species in the Sallé collection. It may be known amongst the forms with a depressed submarginal vitta by the alternate dorsal interstices of the elytra being raised and widened, and the strie placed in double series. Length 15 millim. 17. Lixus mexicanus. (Tab. VII. figg. 9, 9a, 2.) Lizus mexicanus, Boh. in Schénh, Gen. Cure. vii. 1, p. 426°. Hab. Mexico ! (Mus. Brit.), Milpas and Ciudad in Durango (Forrer), Xucumanatlan, Omilteme, and Amula in Guerrero (H. H. Smith), Cuernavaca, Juquila, Parada, | Oaxaca, Istepec (Sallé). Numerous specimens are referred to this perplexing species: four of them (¢ @ ), from Oaxaca, one of which is figured, have the elytra attenuate and acuminate at the apex, as described by Boheman, but in the others (twenty-three in all) the apices are much less produced. The sculpture of the upper surface is variable, the prothorax * Boheman describes L. germari as having a small, rounded, shining scutellum; but this must be an error of observation, due, probably, to the type having been partially covered with efflorescence. 110 RHYNCHOPHORA. being very rugose in some examples; the elytral interstices are rugulose in most of them. The submarginal vitta is placed in a rather broad groove. The rostrum is stout, but varies much in length and thickness ‘in both sexes. The humeri are prominent, projecting a little beyond the hind angles of the prothorax. The larger males have a deep sulcus extending down the first two ventral segments, but this is— not always present. The single example received from Xucumanatlan, a male, apparently belonging here, has the rostrum very short, rugose, and carinate, and the elytra comparatively short and not at all produced at the apex. Length 10-20, breadth 22-64 millim. 18. Lixus limbatus. (Tab. VII. figg. 10, 104, ¢.) Lizus limbatus, Boh. in Schénh. Gen. Cure. vii. 1, p. 427°. Hab. Mexico (Sallé, ex coll. Sturm!; Mus. Brit.), Sierra de Durango (fohr). There are two specimens (¢ 9) of this species in the Sallé collection, and we have recently received a female of it from Durango, the latter (as in one of those in the British Museum) having a line of whitish pubescence on the second elytral interstice (which is slightly depressed), in addition to the submarginal vitta. LL. limbatus is a very close ally of LZ. meaicanus, from which it differs in its smoother rostrum and elytra, the sulcus on the disc of the prothorax extending forward to the apex, and the third elytral interstice wider than the others. ‘he rostrum is also a little less curved, and it is slightly longer in the female than in the male. The apices of the elytra are shortly and obtusely produced. Length 16-17 millim. The Durango specimen is figured. 19. Lixus basilaris, (Tab. VII. figg.11, lla, 3; 12, 124, @, var.) Lizus basilaris, Boh. in Schénh. Gen. Cure. vii. 1, p. 425°. Var. The submarginal vitta of the elytra reduced to a scattered series of piligerous depressions. (Fig. 12.) Hab. Muxtco, Sierra de Durango (Flohr), Toxpam, Yolotepec (Saddé), Almolonga, Jalapa (Hége), Xucumanatlan, Omilteme, and Chilpancingo in Guerrero (H. H. Smith) ; GuatemaLa, Duefias (Champion), Tecpan (Conrad). Not rare in Mexico. This species is nearly related to L. mexicanus, from which it may be distinguished by its narrower, more or less bowed shape (viewed in profile), the very shining, smoother upper and under surfaces, the more slender rostrum (especially noticeable in the females), and the strongly caudate elytra; the last-mentioned character, however, is inconstant, the larger specimens having the apices no more produced than in typical L. mexicanus. The submarginal vitta of the prothorax and elytra is placed in a shallow groove, that of the elytra being often reduced to a series of scattered depressions, each bearing a cluster of white hairs. The second joint of LIXUS. | lil the funiculus is sometimes longer than the first. The first ventral segment is not or very faintly depressed along the middle in the male. About half the numerous examples from Guerrero belong to the varietal form. Length 11$-17, breadth 2—4 millim. 20. Lixus sulcimargo, sp. n. Very elongate, rather shining, black; clothed above with a very short, fine, sparse, greyish pubescence, and with a narrow, depressed, submarginal line of ashy pubescence on the elytra, which is continued forwards along the upper part of the flanks of the prothorax; the under surface and legs cinereo-pubescent. Head closely, minutely punctate, foveate between the eyes; rostrum very stout, feebly curved, shorter than the prothorax in both sexes, shining, not very closely punctate. Prothorax convex, gradually narrowing from the base forwards, the base strongly bisinuate ; densely, minutely, rugulosely punctate, with a few scattered coarser punctures intermixed, the basal depression oblong and rather shallow ; anterior margin with an obtuse tooth opposite the lower angle of the eyes. Elytra very elongate, closely fitting to the base of the prothorax, and here not or but little broader than it, widening to slightly beyond the middle and then narrowing to the apex, the apices somewhat produced ; seriate-punctate, the interstices flat, rugulosely punctate, the seventh depressed. First ventral segment flattened along the middle in both sexes. Body apterous. Length 16-164, breadth 43-5 millim. (d @.) Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). One pair. Very like LZ. teniatus, but with a stouter rostrum, the prothorax not transversely wrinkled at the base, the elytra distinctly dilated beyond the middle, with the anterior margin less thickened, and the apices rather sharp and somewhat produced. From the still more nearly allied Z. apterus it may be separated by the flat elytral interstices, the seventh depressed and with a condensed line of pubescence. 21. Lixus teniatus, sp.n. (Tab. VII. figg. 13, 13a, ¢.) Very elongate, rather shining, black, the antenne partly rufescent; clothed above with a very short, fine, scattered, greyish pubescence, and with a narrow depressed line of longer and denser white pubescence running along the margins of the prothorax and elytra; the under surface and legs cinereo-pubescent. Head closely, minutely punctate, foveate between the eyes; rostrum of the ¢ moderately stout, feebly eurved, a little shorter than the prothorax, closely punctate, that of the 2 slightly longer, and smoother and more shining at the tip. Prothorax convex, longer than broad, subconical, the sides parallel behind in the g; densely rugulosely punctate, and sometimes with a few coarser punctures intermixed, trans- versely wrinkled at the base, the basal depression transverse and rather shallow; anterior margin with an almost obsolete tooth opposite the lower angle of the eyes. LHlytra very elongate, widest at or a little beyond the middle, the basal margin thickened and raised, and projecting laterally beyond the hind angles of the prothorax, the apices separately rounded ; shallowly seriate-punctate, the interstices flat, rugulosely punctate, the seventh depressed. First ventral segment deeply depressed along the middle in the ¢, and flattened in the 2. Body apterous. Length 14-20, breadth 33-53 millim. (¢ @.) Hab.

This line of pubescence is confined to the seventh elytral interstice, and is continued forwards along the flanks of the prothorax, being here scarcely visible from above. 92. Lixus maculipennis, sp. n. (Tab. VII. figg. 14, 14a, ¢.) Very elongate, black, slightly shining ; clothed above with a short, fine, greyish pubescence, the elytra with a fascicle of longer white pubescence placed in each of the shallow, scattered, foveiform depressions of the surface, the under surface and legs cinereo-pubescent. Head densely, finely punctate, shallowly foveate between the eyes; rostrum stout, feebly curved, nearly or quite as long as the prothorax, scarcely longer in the 2 than in the ¢, closely, finely punctate.

Elytra very elongate, broader at the base than the prothorax and gradually widening to the middle ; the basal margin thickened and raised, the apices obtuse or subacuminate ; finely seriate-punctate, the interstices flat and rugulosely punctured, and with a few irregularly scattered, shallow, foveiform depressions, which become more numerous towards the sides or apex. Ventral segments 1 and 2 with a deep groove down the middle in the ¢. Body apterous. Length 14-20, breadth 34-54. (d Q.) Hab. Guatemata, Totonicapam, Cerro Zunil, and Volcan de Agua 5000 to 10,000 feet, Pacific slope (Champion). : Seven specimens. Very like L. teniatus, and perhaps an extreme form of it, but without the depressed submarginal line of white pubescence on the elytra, which is here replaced by scattered, irregularly arranged, piligerous depressions. In one example from Cerro Zunil the apices of the elytra are subacuminately produced, and the rostrum exceedingly stout. 23. Lixus apterus, sp.n. (Tab. VII. figg. 15, 15a, ?.) Elongate-obovate, black, shining, sparsely and very finely cinereo-pubescent, the pubescence closer on the depressed sulci of the elytra. Head foveate between the eyes, closely, finely punctate, with coarser punctures intermixed ; rostrum ( ¢ ) moderately curved, very stout, nearly as long as the prothorax, finely punctate, with a few coarser punctures intermixed, the punctuation becoming sparser and more minute towards the apex, (Q) a little longer, and smoother at the tip. Prothorax convex, conical, longer than broad, strongly bisinuate at the base; densely, rugulosely punctate, with coarser punctures intermixed, more or less sulcate towards the base, the basal depression transverse or triangular, moderately large.

The species are very like the Australian Gonipterina. STERNECHUS. Sternechus, Schénherr, Curc. Disp. Meth. p. 251 (1826) ; Gen. Cure. ili. p. 472 ; Lacordaire, Gen. Col. vi. p. 447.

Robust, subelliptic, black, slightly shining, clothed with very minute, scattered, hair-like scales, the legs witha few short hairs. Head closely punctate, foveate between the eyes, which are large and somewhat narrowly separated ; rostrum very stout, rather sparsely punctured. Prothorax transverse, a little flattened on the disc, very much narrowed and constricted in front and also narrowed behind, the sides rounded at the middle and obsoletely trituberculate ; the surface, except along a narrow smooth space down the middle, closely punctured, the punctuation becoming coarser and rugose towards the sides. Elytra subtriangular, seriate- punctate ; a subtriangular space occupying nearly the basal half of the dorsal surface a little raised and finely granulate, the rest of the surface flat and exceedingly minutely punctate; the fifth interstice with a long conical tubercle before the apex, the humeri much swollen and rounded, the apices separately tuberculate ; the infra-humeral prominence long and conical, swollen at the base. Anterior femora only armed with a short tooth before the apex; all the tibie denticulate along their inner edge, but without longer tooth. Length 14, breadth 7 millim. Hab. Panama, Bugaba (Champion). Very like 8S. tuberculatus, but with a long conical tubercle on the fifth elytral interstice before the apex, the apices themselves tuberculate, the humeri more rounded, the armature of the legs different, and the sculpture of the upper surface also, the latter being difficult to describe and perhaps abnormal in the single abraded example seen. 118 RHYNCHOPHORA. 9, Sternechus bifasciatus, sp.n. (Tab. VII. figg. 26, 26 a, 4.) Subelliptic, broad, robust, moderately shining, black; the upper surface somewhat thickly clothed with minute, piliform, fuscous scales, the elytra with two straight, narrow fasciee of closely-placed whitish scales—one before, the other beyond the middle; the under surface and legs with piliform whitish scales. Head closely punctate, deeply foveate between the eyes, which are rather narrowly separated ; rostrum short and stout, very sparsely, finely punctate. Prothorax strongly transverse, rounded at the sides, narrowing almost from the base and constricted in front, slightly emarginate in the centre at the apex, the lateral margins feebly crenulate; the surface closely, rather finely punctate, with indications of a raised, smooth, median line.

We have received nine specimens of this species from within our limits, these agreeing very nearly with the only one I have seen from Cayenne. Distinguishable by the rugose upper surface and legs, the sparse piliform squamosity, the very prominent, conical, lateral tubercles of the elytra, and the bi- or trituberculate lateral margins of the prothorax. The femora are unarmed. ‘The tibie are denticulate on their inner edge, with one longer tooth before the middle. Length 95-14, breadth 53-8 millim. 11. Sternechus nitidus, sp. n. Subelliptic, bronze-black, shining, clothed with very minute, scattered, hair-like scales, the legs sparsely pubescent. Head and rostrum closely punctate, the latter stout and nearly as long as the prothorax, the eyes rather narrowly separated.

LElytra subcordate, very convex, conjointly rounded at the apex, the humeri obliquely subtruncate and swollen, the infra~-humeral prominence long and bluntly conical; seriate-punctate, the interspaces as wide as the punctures, faintly, transversely wrinkled, and minutely punctate. Femora unarmed; tibie with an acute tooth at the middle and another at the apex, the inner edge denticulate between them. Length 7, breadth 33 millim. Hab. Panama, Bugaba (Champion). One specimen. Very similar to S. spenipes, but with a shorter rostrum, the punc- tuation of the prothorax and elytra less coarse, the humeri not so prominent, the femora unarmed, the surface with a bronzy lustre. STERNECHUS.—PISSODES. 119 12. Sternechus bicinctus, sp. n. (Tab. VII. figg. 28, 28 a, 0.) Subelliptic, broad, robust, shining, black, the antenne and tarsi sometimes obscurely rufescent; the upper surface somewhat sparsely clothed with coarse, narrow, ochreous scales, the elytra with two rather broad fasciee of coarser, white, closely-placed scales—one before and the other beyond the middle, the anterior one widening outwards and interrupted at the suture; beneath sparsely squamose, the squamosity at the sides coarse and ochreous in colour, and piliform and whitish along the middle; the legs with narrow white scales and long hairs. Head closely punctate, shallowly foveate between the eyes, which are narrowly separated; rostrum short and stout, sparsely, very finely punctate.

Oblong-ovate, piceous or rufo-piceous, darker beneath ; the upper surface with scattered, piliform, appressed, whitish or ochreous scales, and with small patches of coarser, broader, similarly-coloured scales on the disc, sides, and base of the prothorax (the two small spots on the dise and one in front of the scutellum being the most distinct), on the scutellum, and at the apex of the elytra, and two oblique irregular fascie of coarse scales on the disc of each of the latter (the anterior one entirely ochreous, the other ochreous, becoming whitish towards the suture); the under surface thickly clothed with coarse, oval, whitish or ochreous scales, the legs with piliform scales. Head and rostrum rugosely punctured, the antenne inserted at the middle of the latter in the ¢, and ata little behind the middle in the 9. Prothorax slightly broader than long, abruptly constricted and much narrowed in front, the sides feebly sinuate before the base, the hind angles acute and directed outwards ; the surface densely, coarsely punctate, the narrow interspaces subgranulate, the disc with an abbreviated median carina. Elytra flattened on the disc, coarsely punctate-striate, the interstices rugulose and rather coarsely granulate, the alternate ones more or less costate.

Norta America!?35, Lake Superior to Georgia*.— Mexico, Omilteme in Guerrero (H. H. Smith). The female scarcely differs from others before me from Boston, U.S.A., but the male has a more coarsely sculptured prothorax and coarsely granulate elytra. Group LISTRODERINA. The affinities of this group, as shown by the Australian genus Desiantha, Pasc., seem to me to be with the Erirrhina (Hydronomides), and not with the Hyperina, amongst which it is placed by all North-American writers. LISTRONOTUS. Listronotus, Jekel, Ann. Soc. Ent. Fr. 1864, p. 566; Leconte, Proc. Am. Phil. Soc. xv. p. 127. The North-American species referred to Listroderes by Gyllenhal were separated by Jekel from that genus under the name Listronotus, and this course has been followed by Leconte, the chief difference being the posteriorly evanescent scrobes in the South- American forms. In L. bagotformis and its allies the first and second ventral segments are connate at the middle, and the scrobes are deep throughout. 1. Listronotus bagoiformis, sp.n. (Tab. VIII. figg. 1, 1a, ¢.) Elongate-ovate, narrow, somewhat depressed, black, the antennz and tarsi partly ferruginous ; thickly clothed with rather large rounded scales, which on the upper surface are mostly of a pale brown colour, variegated with whitish and fuscous, the darker mottling being most distinct on the dorsal portion of the elytra; the elytra with a row of scattered, fine, decumbent sete on each interstice, the rest of the surface and the legs also with scattered hairs. Head and rostrum closely, finely punctate; the rostrum stout, shorter than the prothorax, very faintly carinate towards the tip; the front shallowly foveate; second joint of the funiculus much longer than the first. Prothorax a little broader than long, slightly rounded at the sides, as well as at the base, about equally narrowed in front and behind, the surface densely, rugulosely punctate. Elytra moderately elongate, nearly onc-half wider than the prothorax, very gradually narrowing LISTRONOTUS.—HYPERODES. 12] from the base, conjointly rounded at the apex, the base shallowly emarginate, the humeri broadly and obliquely subtruncate ; finely punctate-striate, the interstices rugulose and almost flat, the fifth feebly | callose towards the apex. Beneath closely punctate, with scattered intermixed coarser punctures. Venter strongly depressed down the middle of the first two segments in the ¢. Length 5-63, breadth 2-23 millim. (¢ 9.) Hab. Muxtco, near the city, probably from the banks of the large lakes (Hoge). 7 Eleven specimens. Very like the North-American LZ. latiwsculus (Boh.), but with longer sete on the elytra (these not being at all clubbed) and the seriate punctures on the latter not so coarse. 2. Listronotus —— ? Hab. Mexico, Vera Cruz (Hége). A single female specimen, too worn for description. This insect is very like L. bagoiformis, but differs from it in having the rostrum distinctly carinate, the elytra piceous in colour, very coarsely seriate-punctate, with the interstices convex and sparsely rugulose, the under surface more coarsely punctured, and the tibie ferruginous.

Hyperodes hirtella. Macrops hirtelius, Dietz, Trans. Am. Ent. Soc. xvi. p. 46 (1889) '. Elongate-ovate, shining; varying in colour from black to ferruginous, pale specimens sometimes having a common black patch on the elytra or a longitudinal black vitta on the disc of each of them; the upper surface with scattered, coarse, erect, blunt sete, and when fresh clothed with large, rounded, loosely attached griseous or brownish scales, which tend to form vitte on the prothorax and irregular spots on the elytra; the legs setose. Head and rostrum densely, rugulosely punctate; the latter short and stout, dilated at the apex, shallowly foveate at the base, and more or less distinctly tricarinate ; joints 1 and 2 of the funiculus subequal in length, 1 stouter than 2. Prothorax transverse, rounded at the sides, coarsely, densely punctate. Elytra one-half wider than the prothorax, slightly hollowed at the base, subparallel to near the middle, and a little produced at the tip; coarsely punctate-striate, the punctures closely placed, the interstices somewhat convex, shining, not wider than the strie, and each with a row of seta.

Jalapa (Hége); Guatremata, San Gerdénimo (Champion); Nicaragua, Chontales (Janson); Panama (Mus. G. & S.). The twelve specimens obtained by us agree so closely with the description of M. hirtellus that there can be little doubt as to their identity; the three from Chontales, however, have the elytral sete almost entirely confined to the alternate interstices, as in 1. sparsa &c. 2. Hyperodes testaceipes, sp. n. (Tab. VIII. figg. 2, 2a.) Elongate-ovate, somewhat depressed, slightly shining; piceous, the antennew, the anterior margin of the prothorax, and the legs ferruginous or testaceous ; the upper surface with scattered, erect, blunt setze and minute, appressed, piliform scales, and when fresh thickly clothed with large rounded pallid scales ; the legs setose. Head and rostrum rugulose; the latter short and stout, dilated at the apex, shallowly foveate at the base, and tricarinate ; joints 1 and 2 of the funiculus subequal in length, 1 stouter than 2. Prothorax transverse, rounded at the sides, densely, finely punctate, and sometimes with indications of a faintly raised, smooth, median line. Elytra one-half wider than the prothorax, subparallel to near the middle, slightly hollowed at the base, and a little produced at the tip; rather coarsely punctate-striate, the punctures closely placed, the interstices about as wide as the striw, feebly convex, rugulosely punctate, the alternate ones each with a scattered row of sets, the minute piliform scales conspicuous when the larger ones are abraded. Length 34-34 millim. Hab. Mexico, San Juan Bautista in Tabasco (Hoge). Three specimens, their sex not ascertained. Very like H. hirted/a, but differing from it in the finely punctured prothorax, the less coarsely punctured striz, and the rugulose elytral interstices, the alternate ones only with a scattered row of sete. ‘The minute piliform scales are conspicuous when the larger ones are removed. 3. Hyperodes angustata, sp. n. (Tab. VIII. figg. 3, 3 a.) Elongate, narrow, rufo-piceous, the elytra mottled with black; the upper surface clothed with scattered, erect, blunt sets, and small, narrow, appressed, ochreous scales, without larger rounded scales ; the legs setose. Head finely punctate; rostrum short and stout, widened at the tip, rugosely punctate, faintly foveate at the base, without distinct carina above; joints 1 and 2 of the funiculus subequal in length, 1 stouter than 2. Prothorax slightly broader than long, rounded at the sides, somewhat coarsely, closely punctate. Elytra about one-half wider than the prothorax, subparallel to near the middle, rather coarsely punctate-striate, the interstices convex, shining, and about as wide as the stris, and each with a row of sete. Length 32 millim. Hab. Britiso Honpuras, Rio Hondo (Blancaneauz). One specimen in very clean condition. Narrower and more cylindrical than either of the preceding, the rostrum not carinate above, the surface without larger rounded scales, which, however, may be rubbed off. CERATOPUS. 123 Group CERATOPINA. Cératopides, Lacordaire. This group seems to me to be nearly allied to the Erirrhina, from which it is widely separated by Lacordaire. CERATOPUS. Ceratopus, Schénherr, Gen. Cure. vii. 2, p. 120 (1843) ; Lacordaire, Gen. Col. vi. p. 591. Acanthobrachium, Boheman, Freg. Eug. Resa, Ins. p. 128 (1859) ; Lacordaire, loc. cit. p. 592. The various new forms now described show that Ceratopus and Acanthobrachium cannot be maintained as distinct, the only difference (following Lacordaire) being the ereater extension of the scrobes posteriorly in the latter. They are easily recognizable by the very large triangular tooth on each of the femora and the appendiculate tarsal claws. The genus is peculiar to Tropical America, ranging from the Mexican State of Vera Cruz to Brazil. The seven species here enumerated may be grouped thus :— a. Scrobes becoming shallow or evanescent beneath the rostrum posteriorly, thus appearing confluent behind; tibial claw short or absent.

Four specimens have been received by us. 2. Ceratopus subfasciatus, sp. n. (Tab. VIII. figg. 5, 54, 2.) Elongate-ovate, shining, piceous, the basal half of the antenne rufescent ; somewhat thickly clothed with small, oblong, intermixed, cinereous and brown scales, the darker scales forming two incomplete fascize and various spots or streaks on the elytra, the latter with a small pale ochreous spot (surrounded by brown scales) on the fifth interstice towards the apex ; the squamosity of the under surface cinereous. Head closely, minutely punctate; rostrum elongate, twice the length of the prothorax, finely punctured at the sides towards the base, and there carinate, for the rest smooth and shining; antenne inserted slightly before the middle of the rostrum, joint 1 of the funiculus about twice as long as 2, the club nearly as long as joints 4—7 united.
