PBIffTED BY TAYLOB AND FBANCIS, , . RED LION COURT, FLEET STREET. PREFACE, This series (of which the present is the first part) has the same - object and scope as the series of ' Illustrations of Typical Specimens of Lepidoptera Heterocera,' viz. to give illustrations, accompanied by diagnoses or short descriptions, of those specimens of Coleoptera in the British Museum from which species have been described in other works, or are* described now for the first time. The several parts will be devoted as much as possible td species belonging to the same Family or the same Fauna; The descriptions of this first part have been prepared by Mr. C. 0. Waterhouse, one of the Senior Assistants in the Department of Zoology. ALBEET GIWTHEE, Keeper of the Department of Zoology, British Museum, November 22, 1879. 295470 SYSTEMATIC INDEX. LYCIDiE.

Thorax subquad- rate, rather straight at the sides, arched in front, with a deep mesial longitudinal channel, and on each side two deep foveae, the raised portion dividing the foveas oblique. Penultimate segment of the abdomen triangularly emarginate at the apex, and with a deep lon- gitudinal mesial channel. $ . Antennae two thirds the length of the elytra ; third joint as broad, at its apex as long, fourth to ninth scarcely longer than broad, the tenth a little narrower, eleventh narrowed at the apex. Thorax a little broader than long, rather narrowed in front. The rest as in the male. Calochromus rugatus. (Plate I. fig. 4.) Waterh., Cistula Ent, ii. 1877, p. 199. Elongatus, niger ; elytris piceo-testaceis, dense rubro-sericeis, striis impressis, interstitiis convexiusculis, secundo et quarto fere costatis. <3 . Long. 5| lin. Hah, Allahabad (J. G. Bowring, Esq,). Head gently convex, impressed on the forehead; rostrum ex- tremely short, the space between the antennal pit and the base of the mandible about half the diameter of the antennal pit. Antennae about two thirds the length of the elytra and (for the genus) rather slender ; the sixth to tenth joints slightly diminishing in length and a trifle more slender ; eleventh joint a little longer, parallel, scarcely acuminate at the apex. Thorax black, margined, delicately pubes- cent ; disk transversely impressed behind the middle, deeply im- pressed in front of and behind the oblique lateral ridge. Penultimate segment of the abdomen with a deep incision. Calochromus ruber. (Plate I. fig. 6.) Watwh., Cistula Ent, ii. 1877, p. 199. Elongatus, niger, supra piceo-testaceus, dense rubro-sericeus ; CAL0CHR0MT7S. O thorace medio longitudinaliter canaliculato, lateribus bifoveatis ; elytris minus elongatis unicoloribus, obsolete bicostatis. 2 . Long. 5| lin. Hab. Allahabad (J. C. Bowring, Esq.). Antennae compressed ; the third joint as long as the two preceding together ; fourth a little longer, truncate at the apex ; fifth to ninth nearly the same form, but gradually more obliquely truncate at the apex, so that the lower anterior angle becomes more acute but is not produced; the tenth joint is rather smaller, very obliquely trun- cate ; the eleventh narrow, parallel, acuminate at the apex. This species is very close to 0. rugatus, but the lateral oblique ridge of the thorax is placed more posteriorly, and the lateral im- pressions are not so well defined ; the space between the antennal pit and the base of the mandible is also much greater. Calochromus velutinus. (Plate I. fig. 7.) Waterh., Cistula EnL, ii. 1877, p. 199. Elongatus, piceo-niger, supra piceo-testaceus, dense flavo-rufo- sericeus ; thorace sat transverso, medio canaliculato, utrinque for- titer impresso ; elytris obsolete bicostatis ; abdomine cyaneo-nigro. Long. 5 1 lin. Hab. Burmah (J. C. Bowring, Esq.). Eather shorter and broader than C. ruber, the thorax more trans- verse, and with the ridge which divides the lateral impressions much more directed forwards ; rostrum almost none, i, e., the space between the antennal pit and the base of the mandible is less than half the diameter of the pit, whilst in C. ruber this space is quite equal to the diameter of the antennal pit. The third joint of the antennae is as long as the first, as long as its greatest width, obliquely truncate at the apex ; the fourth joint as long as the two preceding together, a little longer than broad, very little narrowed at the base, straight at the apex ; the fifth to tenth about the same length as the fourth, but gradually diminishing in width, scarcely oblique at the apex, their lower anterior angle a little less than a right angle ; the eleventh joint much narrower, longer, parallel, acuminate at the apex. The thorax one sixth broader than long, a little nar- rower in front ; disk convex, with a rather fine mesial channel ; the sides deeply impressed, the usual oblique ridge very much directed forwards, almost parallel with the lateral margin. Elytra very gra- dually and very little enlarged posteriorly ; each elytron with two narrow slightly raised costae, with an indication of a third. Calochromus segregatus. (Plate I. fig. 8.) Depressus, cyaneo-niger ; thorace elytrisque ochraceo-rufis ; 6 LYCTDJE. thorace sat depresso latitudine paulo breviori, medio linea tenui im- presso; elytris striis plurimis. $ . Long. 4 J lin. Hab. Java (J. O. Bowring, Esq.). Most nearly allied to C. velutinus, but more depressed.

Long. 3 J-4| lin. Hab. Java ( <$ ), Penang ( 5 ) (J. 0. Bowring, Esq.). A more slender species than any of the preceding, and rendered distinct by the beautiful shining blue thorax and violet antennae. The anterior angles of the thorax are much deflexed, and conse- quently do not show the margin so distinctly ; the disk has not a fine mesial line, but a deep longitudinal impression ; the lateral fossae are deep, but the oblique ridge which divides them is not so well defined as in most of the species. d . Antennae rather slender. Elytra with scarcely any trace of costae. Penultimate segment of the abdomen with a deep incision. 2 . Antennas very slightly dilated. Thorax more narrowed in front. Elytra bicostate. The two examples in the collection are from different localities, but there is no doubt that they should be associated as sexes of the same species. Calochromus longipemris.

Elongatus, subparallelus, niger ; thorace supra piceo, dense rufo- pubescente, medio foveola lanceolata impresso, lateribus biimpressis ; scutello piceo, rufo-pubescente ; elytris longissimis, dense rufo- pubescentibus, ad apicem nigris, costatis, costis angustioribus. $ • Long. 6 J lin., lat. 1|- lin. Hab. Sumatra (E. C. Buxton, Esq.). Eorehead evenly convex, black, very finely pubescent, rostrum about three times as broad as long ; maxillary palpi very stout. Antennae three quarters the length of the elytra, compressed ; the third joint about twice as long as broad, emarginate at the apex ; the fourth to ninth joints about equal in length, the lower anterior angle obliquely and much produced, increasingly so as they approach 8 LYCXDJE. the apex ; the tenth joint very oblique, a little smaller than the ninth, the eleventh compressed, fusiform. Thorax a little broader than long, somewhat narrowed in front, all the angles distinct but obtuse, with bright red pubescence ; the disk convex, with a deep lanceolate fovea nearly reaching from the anterior to the posterior margins. Elytra very long, with bright red pubescence ; each elytron with three not very distinct narrow costse, the outer one very obsolete. There can be no doubt that Micronychus bimaculatus, Motsch. (Bull. Mosc, 1861, i. p. 138), from Ceylon, is closely allied to 0. longipennis. It differs from it in having the forehead clothed with bright red pubescence, the thorax is much longer, the anterior angles are more deflexed, and the lateral fold is not so near the posterior angles. The British-Museum example has the elytra uniform bright red, the costse are not so prominent as in C. longi- pennis. Section III.

Hab. Borneo (J. Russell). This species has somewhat the appearance of C. orbatus^ but has the elytra more ample posteriorly, less bluntly rounded at the apex, and the thorax is margined all round. The antennae are nearly as long as the elytra, not very approximate at their base. Clypeus gently emarginate. Intermediate coxae with a strong acute spine ; the femur with a strong tooth near tbe base; the intermediate and posterior tibiae strongly curved. The penultimate segment of the abdomen is deeply notched in the middle. DEMOSIS. Lycus (genus 4), WaterL, Trans. Ent. Soc, 1878, p. 97. Antennae short, compact, dentate, of equal width throughout ; the third joint a trifle longer than broad, the fourth to tenth joints transverse. Eostrum distinct but short. Thorax rather transverse, quadrangular ; the disk smooth, the margins reilexed. Elytra flattened, subparallel, with moderately distinct costae, the intervals punctured. LIPERNES. » Demosis peltatus.

Nearly parallel, the elytra very little wider than the thorax. Head and the basal joints of the antennae very slightly pitchy. Thorax nearly one third broader than long, yellow, shining and black in the middle ; the sides subparallel, reflexed, the posterior angles very slightly prominent. Elytra very finely pubescent, widest rather before the middle ; each elytron with four obtuse costae, the third abbreviated, the fourth continued over the shoulder, the intervals rugulose and obscurely punctured, the apical third black. At the time my account of the genera of Lycidce was written (Trans. Ent. Soc, 1878) this species was considered to be the Lycus scrobicollis of E&hraeus, and is the species referred to under " Genus 4 " at p. 97. I have, however, since seen a different species named L. scrobicollis, one which in some respects agrees better with Paliraeus's description. It seems best therefore to consider the insect from Lake N'Gami a new species. LIPERNES. Characters of Lycostomus, but with the palpi short and thick ; the apical joint of the maxillary palpi nearly as broad as long, convex, nearly straight on the outer side, rounded on the inner side.

This species is very close to L. ferrugineus, E., but is relatively a little shorter, and the elytra are less parallel, more ample poste- riorly and more evidently arcuate at the sides. The antennae are distinctly more slender. The thorax varies immensely in form, but is generally narrower in the ^ than in the $ ; the disk is black, frequently traversed by a fine mesial red line. The elytra are en- tirely deep red ; a single example only has a short blackish stripe on the second interstice. L. ferrugineus, F. (Ent. Syst. Suppl., p. 125), with which the pre- sent species is above compared, will very probably prove to be a variety of Lycus marginatus, Eabr. (Syst. EL, ii. p. 110). L. mela- nurus, Blanch. (Toy. Pole Sud, iv. p. 74, t. 6. f . 2), and L. biviu tatus, Kirsch (Mittheil. aus. d. k. zool. Museum zu Dresden, 1875, i. p. 34), are evidently synonymous with marginatus. Lycostomus aequalis.

Sometimes there is only a black lateral spot, and an apical border parallel with the margin as in L. elegans, but generally the black at the apex is suffused. Sometimes the lateral spot is more or less united with the black at the apex ; it is so slightly in the type spe- cimen ( J ) of L. latissimus, in the Linnean collection. The variety L. Jiarpago, Th., has the two lateral spots united by a fascia. Variety fenestratus, Murray, has this fascia and the black at the apex con- fluent. Sometimes the elytra are entirely black except a yellow fascia. The extent to which the elytra are dilated in the male and the form of the apical truncature appear to vary considerably, while the various systems of coloration above mentioned are not constantly accompanied by any one form of elytra. With regard to the synonymy given above, it must be noticed that Fabricius does not mention the black in the middle of the thorax, for which reason Guerin (Eev. Zool., 1847, p. 227) provisionally re- named the Fabrician insect Fabridi. There can, however, be little doubt that the omission was an oversight on the part of Fabricius, especially as the examples in the Banksian collection (said to have been named by Fabricius) are typical latissimus, the male example having the lateral spot on the elytra partly united with the black at the apex as in the Linnean type. The description given by Olivier applies well to latissimus, Linn, ; but his figure (Ent., ii. 29, t. 1. f. 2) represents quite a distinct species allied to L. anvpliatus, Fahr., and is almost certainly the male of the species which he names L. probosddeus* (Ent., ii. 29, p. 8, t. 1. f. 6). BROXYLUS. Rostrum none. Apical joint of palpi very large, long, knife- shaped. Antennae very compressed, simple. Thorax with an in- terrupted mesial carina. Elytra very ample, inflated, quadricostate, the interstices divided into subquadrate spaces by transverse carinae. The species upon which this genus is founded closely resembles Calopteron dilatatwm, Bourgeois, but differs in the form of the palpi. * This species as well as ferrugineus, Fab., lateralis, Dalm., and perhaps some other Fabrician species of Lycus t appear to be omitted from Q-emminger and t.

Elytra at the base not wider than the thorax, gradually but not much wider posteriorly, the three spots on each elytron are rather pale dusky. Since this species was originally described I have come to the conclusion that it is only a variety of the American Calopteron tri- color, Oliv. ; in which case the locality with which it is marked must be an error. 0. tricolor usually has the tibias dusky, which is not the case in the specimen described as notatum ; but the species is very variable.

Very close to O. dorsale ; but besides the absence of the anterior fascia of the elytra, it differs in having the elytra rather less widened in the apical region, and less undulating above. The thorax has generally the sides broadly margined with yellow, but in some spe- cimens it is almost entirely black. With regard to the three foregoing species, C. typicum, C. dorsale, and C. divisum, it must be observed that the synonymy given in Dr. Le Conte's i List of Coleoptera of N. America,' and followed in Gemminger and Harold's Catalogue of Coleoptera, is evidently in- correct. C. apicale, Le C, is placed as a variety of typicum ; and in the footnote Dr. Le Conte states that " from some clerical error in the description, divisa, Newman, is irrecognizable, but is probably the same as apicalis, Le C." The clerical error alluded to is that New- man wrote " elytra basi nigro," instead of " apice nigro." It is OSNIA. — CELETES. 23 possible that divisum may be a variety of dorsale, but it is certainly not a variety of typicvm. Secondly. 0. dorsale, Newm., is placed as a variety of reticulatum, Fabr. (Syst. Ent., p. 203). The description of this latter does not, however, accord with dorsale. The expressions " Statura P. [Pyro- chroa] bicoloris, at duplo major," " Elytra plana," " sterno flavo," are better applied to typicum than to dorsale* OENIA. Newm., Entom. Mag,, 1838, v. p. 381.

Elytra only slightly wider at the apex ; each elytron with four costae, the interstices divided into square or slightly transverse spaces by transverse nervures. The fourth to tenth joints of the antennae in the male emit from the base a some- what long, slender, compressed branch. The female has the antennae strongly dentate, and the thorax is strongly constricted in the middle, which causes the posterior angles to appear much more diverging. EUKRHACUS. Kostrum none. Apical joint of the maxillary palpi elongate, cultriform. Antennae long, the third to tenth joints each with a long, compressed branch springing from the base of the joint. Tho- rax with a mesial carina, which is doubled in the middle. Elytra pubescent, parallel ; each elytron with nine costae, only four distinct, the interstices with a single line of punctures. The cultriform apical joint of the palpi and the flabellate antennae at once separate this from Emplectus, after which it should be placed. Eurrhacus tristis. (Plate VI. fig. 5.)

In my original manuscript the genus Plateros was intended only to include Eros lictor, Newm., and other American species ; a more detailed examination of the species, however, has induced me to include in it the Asiatic forms separated originally under the head of "Genus 16" (Tr.

Thorax not quite so short as in lictor, more rounded in front, the posterior angles a little less diverging. Elytra rela- tively a trifle less long, the shoulders margined with dark reddish yellow. The coxae and the extreme base of the femora yellowish. The species of this group are very variable, and it is difficult to arrive at any definite conclusion as to the identity of the species described by Newman with those of other authors. I think, how- ever, that there is little doubt that alatus, N., is the female of lictor, N., corresponding respectively to timidus, Le C, and ceger, LeC, which, according to Dr. Le Conte himself, are synonymous with modestus of Say (Bost. Journ., i. p. 153). See Le Conte, Journ. Ac. Phil. ser. 2, i. p. 80, and List of the Coleopt. of N. Amer. p. 51. The reference in Gemminger and v.

Cautires excellens, var. 5 , This variety (as it seems best to consider it for the present) differs from the female of C. excellens from Borneo in being rather smaller, in having the base of the elytra more red, but especially in having the joints of the antennae differently formed ; the branches arise from the base of the joints, and not from the apex, being thus somewhat intermediate in form between the male and female of the Bornean examples.

It differs, however, in having the thorax and elytra of a uniform colour, the antennae are much more strongly dentate, the thorax does not present the same roughness in front, and the trans- verse costee of the interstices of the elytra are further apart, the spaces divided by them being nearly squares, even in the lateral interstice. Xylobanus foveatus. (Plate X. ftg. 2.) This species differs from the preceding in having the thorax and elytra of a dull yellowish red. The antennae are very strongly dentate ; the thorax has the posterior angles not diverging, and the mesial posterior areolet, instead of terminating in the middle of the disk, extends much more forward.

This closely resembles X. humilis, but the areolets of the thorax are not so well defined ; the elytra have the same four strong costae, but the transverse costae are black, less distinct and much closer together, and the interstices have a more woolly appearance. Xylobanus indutus. (Plate X. Ag. 10.)

This and the following species are somewhat aberrant forms, and are therefore placed at the end of the genus. Xylobanus mixtus. (Plate XI. fig. 5.) Brevior, atro-fuscus, opacus, pubescens ; thorace septemareolato ; elytris quadricostatis. Long. 3^ lin. Hah, Waigiou (Wallace). Dark fuscous, with the incrassated lateral margin of the thorax rather paler. The posterior angles of the thorax are slightly diverging and acute; the seven areolets are well defined. Each elytron has four distinct costae, and in the first and fifth inter- stices, as well as at the base of the second, third, and fourth, a fine intermediate costa may be traced ; the interstices have numerous transverse costae, placed somewhat close together, dividing the sur- face into strongly transverse quadrangular spaces, except the first and fifth interstices and the extreme base of the others, which have two rows of irregular punctures, these rows being divided by the fine intermediate costae above mentioned. This species is of particular interest, on account of its showing the commencement of the intermediate costae on the elytra met with in Metriorrhynchus, P0RR0ST0MA. Castelnau, Silbermantis Rev.

Elytra parallel ; each elytron with four complete strong costae, and four in- termediate ones at the base ; the first and second of the intermediate costae are traceable nearly to the apex of the elytra ; the interstices are closely punctured. The ridges which divide the thoracic areolets are very obtuse. In the British-Museum collection are several specimens of a species from Celebes which I have determined to be Lycus thoracicus, Eabr. (Syst. EL, ii. p. 117), with which M. cyanoptems, Bedt., seems to be synonymous. M. flavicollis diifers from these in having the elytra black, the thorax is more convex on the disk, the sides are less re- flexed, and the mesial areolet is very strong and deep ; whereas in M. thoracicus the mesial areolet is almost obliterated. The elytra are very similar in sculpture, but in thoracicus the interval between the third and fourth costae has two lines of very close transverse punctures which meet in the middle of the interstice ; in flavicollis the punctures in this interstice are less straight, transversely ovate, and they do not meet so closely in the middle of the interstice.

Varieties. Thorax with the elevated lines rusty yellow, or with the entire thorax red. One specimen from Penang has the elytra almost entirely yellow, with only the apex black, the punctures dusky. I think there can be no doubt that this is the Diet, lineatus, Kirsch ; that author's name is, however, most unfortunately preoccu- pied for a species named by Hope. It appears somewhat doubtful whether this should be separated as distinct from Lycus incequalis, Pabr.* (Syst. EL, ii, p. 112). The specimens in the Museum col- lection which I have determined to be the Pabrician species average a little larger ; the strong costse of the elytra are of equal thickness throughout, and the intermediate costae are very fine, not more elevated at the base, and are visible throughout the whole length. Metriorrhynchus kirschii, var. ? (Plate XII. fig. 10.) This differs from what I have above described as M. Jcirschii in having the mesial areolet of the thorax more obtuse in front and more removed from the anterior margin ; the intermediate costse of the elytra are distinct and equal throughout their length.

Elytra similarly sculptured to the preceding ; but the elytra being a little narrower, the inter- stices are narrower, and consequently the transverse cost© are shorter.

Aru I. and Dorey ( Wallace). Yery close to M. ephippiger, Guerin, but appears to be distinct. The basal third only of the elytra is yellow, and the line of demar- cation is very sharply defined and nearly straight. The thorax is more distinctly blue-black, and the mesial areolet is very broad at the anterior third, at which part it occupies one third the width of the thorax. The elytra have each the same eight costae, the inter- mediate ones being scarcely raised ; the punctures in the interstices are sometimes round, and in the broader females they are close and strongly transverse. The male example is much smaller than the female, and has the scutellum yellow. The specimen in the Museum collection which has been deter- mined to be M. ephippiger, Guerin (Voy. Coquille, p. 73), is from Dorey ; it is a male, and measures 6| lines in length. There is another specimen from Waigiou, a female, which differs 54 lycid^:. from that from Dorey in being relatively considerably shorter ; the discoidal thoracic areolet is extremely narrow ; the elytra have the lines of punctures rather stronger, and the punctures are more transverse. This specimen may prove to belong to a distinct species. Metriorrhynclms nobilis. (Plate XIII. tig. 3.)

Elytra with the eight costse very distinct, the alternate ones less elevated in the middle of the elytra, but equally distinct at the base ; the interstices have each a single line of close, strong punctures. The yellow at the apex of the elytra extends for rather more than one third of their length. At some little distance from the apex the fifth and seventh fine costee are united to the sixth; and the fifth and sixth, and the seventh and eighth lines of punctures become united, the punctures then being transverse. I believe these abbreviated costae to be a malformation ; but the two elytra being exactly similar, it may be normal. Metriorrhynchus vagans. (Plate XIII. fig. 10.)

Each elytron has eight costae, the alternate ones rather narrower and less elevated ; the punctures in the lines are distinct and rather strong. The type specimen and other specimens from Australia have the disk of the thorax black. The other examples, from Aru I., Batchian, and Torres Straits, have the thorax entirely reddish yellow, except one example from Aru I., which has a little dusky mark. These specimens differ, moreover, in having the sterna and base of the femora also reddish yellow. The males have the antennae pectinate. In the females they are only dentate (Plate XIV. fig. 10).

In the British-Museum collection there are three female examples, which differ from the type in having the antennae less broad, less strongly dentate, more tapering towards the apex, and apparently, also, rather shorter ; they hare, moreover, the thorax entirely red. One of these specimens was received from Sumatra with the type examples, one is from India, and the other from Java from Mr. Bowring. There is also a single example, without locality, having the red thorax, which has the antennae broad, as in the type example. It seems best, at least for the present, to consider these specimens varieties of the same species. The example which I named M. velutinus (Trans. Ent. Soc, 1878, p. 110) has the mesial areolet of the thorax black, and the antennas less robust ; but I believe this will prove to be a variety of C. signi- collis, Kirsch, Conderis major.

The male has the antennae flabellate ; in the female they are simply dentate. Cladophorus ornatus. (Plate XYI. fig. 1.) Niger, opacus ; thorace, scutello, elytrorum fascia lata, pectore, abdomine basi, femorumque basi late flavis. d . Long. 4^ lin. Hah. New Guinea ( Wallace). A species at once known from all its allies by the remarkable coloration of alternate clear yellow and dull black. Thorax with seven areolets , the mesial one only distinctly defined ; the anterior border and the sides are punctured. Elvtra dull black, with a broad yellow fascia rather before the middle ; each elytron has four costae, the intervals with two rows of punctures (which are only distinct in the yellow part), the rows divided by an extremely fine line. Cladophorus aberrans. (Plate XVI. fig. 3.) Waterk, Tram. Ent. Soc, 1878, p. 112. Fuscus, pubescens ; antennis brunneis, ramis fusco-nigris ; thorace sordide testaceo, medio parum constricto ; scutello apice fere truncato ; elytris quadricostatis, interstitiis fortiter transversim punctatis, basi costis intermediis brevibus ; humeris brunneo-testaceis ; coxis pal- lidis. Long. 4 lin, Hub. Aru Island ( Wallace). Antennae brownish, with the apex of each joint and the branch (which is a little longer than the joint itself) blackish. Thorax pale testaceous, divided into seven distinct areolets. Elytra with the shoulders and the basal half of the suture and extreme lateral margin brownish ; each elytron with the four costae distinct, those near the base turn away from the scutellum ; the interstices are strongly punctured with transverse punctures ; in the first, second, and third interstices there are short intermediate costae near the base. m Cladophorus restrictus. (Plate XYI. fig. 5.) Waterh,, Trans. Ent. Soc, 1878, p. 113. Euscus, pubescens ; antennis longe flabellatis ; thorace septem- areolato, lineis elevatis limboque pallidis ; elytris basi ipsa anguste sordide flava, quadricostatis, interstitiis biseriatim obsolete subtiliter pimctatis ; femorum basi genubusque sordide flavescentibus. Long. 4 lin. Hab. Waigiou ( Wallace). Thorax a little narrowed in front, the sides somewhat straight ; the four anterior areolets nearly equal, the incrassate margins testa- ceous, the elevated lines pale pitchy. Scutellum deeply emarginate at the apex. Elytra a little narrowed in their middle, with the four costae fine, the second and third slightly turn from the scutellum near the base ; near the base and at the apex a very fine short costa may be seen between each pair of the complete costae, but those at the apex are very obscure. This species is somewhat aberrant in this genus on account of the costae of the elytra not being parallel to the suture near the base. The branches of the middle joints of the antennae are about six times as long as the joints themselves. ENICLASES. Antennae long, somewhat dentate. Thorax narrow, with seven areolets, the two lateral ones imperfectly divided; the posterior angles acute, prominent. Scutellum somewhat rounded posteriorly, with a small notch at the apex. Elytra with seven costae, the first trifurcate at the base ; interstices with a single line of punctures. Legs very long, compressed. I only know of one species, Lycus (gen. 35) luteolus, W., which has the scutellum formed as in this genus. Eniclases luteolus. (Plate XVI. Rg. 12.) Lycus (gen. 35) luteolus, Waterh., Tram. Ent. Soc, 1878, p. 113. Flavus; antennis infuscatis, thorace marginibus evidenter pimc- tatis, septemareolato, angulis posticis valde acutis ; scutcllo subro- tundato, postice medio acute exciso ; elytris opacis septemcostatis, costa prima basi trifurcata, seconda, quarta et sexta magis elevatis, interstitiis sat fortiter transversim punctatis. Long. 5| lin. Hah. Aru Island and Dorey ( Wallace). Thorax rather long, narrowed anteriorly, a little enlarged before the posterior angles ; the anterior and lateral margins are rather TKICHALTTS. 67 strongly punctured ; the surface divided into seven areolets, but the lateral ridges scarcely join the mesial lanceolate areolet. This species must not be confounded with Trichalus acutangulus, which it closely resembles; but that species has the thorax less narrowed in front, and the scutellum is formed in the ordinary manner. TRICHALUS. Waterh, Trans. Ent. Soc., 1877, p. 82. The species of this genus resemble those of Metriorrhynchus, but have only a single discoidal lanceolate areolet to the thorax, and the elytra have the first costa divided into three at the base ; or, in other words, they have nine costas, the first and third being abbreviated and united to the second not far from the base, so that there are only seven costse posteriorly. Trichalus flavopictus. (Plate XYI. ^g. 11.) Waterh., Trans. Ent. Soc., 1877, p. 82, pi. ii. figs. 92-96. Niger; thorace ochraceo, utrinque biimpresso, disco areola lan- ceolata, in imo nigra, bene impresso ; scutello nigro ; elytris postice paulo ampliato, ochraceis, apice nigris, septemcostatis, costis alternis minus elevatis, costa juxta suturam basi trifida, interstitiis reticulato- punctatis ; coxis femorumque basi flavis. Long. 3|-6| lin. Hah. Port Bo wen. c? . Antenna? long and broad, third to tenth joints gradually be- coming shorter. Thorax reflexed at the sides ; the disk raised, and with a deep longitudinal fovea, joined to the front margin by a carina. The penultimate segment of the abdomen is notched in the middle. $ . Antennas less strongly dentate. Thorax straighter at the sides. Elytra a little more parallel. Abdomen simple. Trichalus ampliatus. (Plate XVI. fig. 7.) Waterh., Trans. Ent. 8oe., 1877, p. 83, pi. ii. figs. 97-101. Niger ; thoracis lateribus elytrisque rufis ; rostro brevissimo ; antennis sat longis ; thorace lateribus modice reflexis, medio nitido, disco impressione haud profunda instructo ; elytris postice paulo ampliatis, septemcostatis, costis alternis minus elevatis, costa juxta suturam basi trifida. iloohromu'o dispar.
