This series (of wliicli 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 JBritish 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 to 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. ALBERT GUNTHEE, Keeper of the Department of Zoology. British Museum, November 22, 1879. SYSTEMATIC INDEX.

Niger, subopacus ; thorace medio canaliculato, utrinque biim- presso ; elytris dimidio basali ferrugineo-flavo, singulis tricostatis. Long. 3|-4| lin. Hah. Sarawak {Wallace). Head convex, shining, rather closclj- and excessively finely punc- LTCID^. tured ; rostrum very short, strongly transverse ; at the base of each antenna there is a slight round tumour ; mandibles pitchy. Thorax shining, clothed with very delicate grey pubescence, only visible in some lights. Elytra densely pubescent; each elytron with three distinct roof-like costfe, and with an indication of a fourth. (S . Antennse nearly as long as the elytra ; third joint a little elongate, very obliquely truncate at the apex : fourth joint as long as the two preceding taken together, compressed, broader than the third ; the fifth to tenth the same length as the third, the eighth, ' ninth, and tenth diminishing in width, the fifth to eighth Avith the lower anterior angle a little produced, the eleventh joint a little longer and much narrower than the preceding. Thorax subquad- rate, rather sti-aight at the sides, arched in front, with a deep mesial longitudinal channel, and on each side two deep fovese, the raised portion dividing the fovese oblique. Penultimate segment of the abdomen triangularly emarginate at the apex, and with a deep lon- gitudinal mesial channel. 2 . 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 rugatiis. (Plate I. fig. 4.) Waterh., Cistida Ent., ii. 1877, p. 199. Elongatus, niger ; elytris piceo-testaceis, dense rubro-sericeis, striis impressis, interstitiis eonvexiusculis, secundo et quarto fere costatis. 6 • ^^^S' H 1^"- Hah. Allahabad (J. C. 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. Antennse 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.) Waterh., Cistula Ent., ii. 1877, p. 199. Elongatus, niger, supra piceo-testaceus, dense rubro-sericeus CAL0C1IR0MU3. thorace medio longitiuliiialiter canaliculato, lateribus bifoveatis ; elytris minus elongatis uuicoloribus, obsolete bicostatis. 5 . Long. 5| lin. Hah. Allahabad {J. C. Bowrlng, Esq.). Antennte 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 tho apex, so that the lower anterior angle becomes more acute but is not produced; tho tenth joint is rather smaller, very obliquely trun- cate ; the eleventh narrow, parallel, acuminate at the apex. This species is very close to G. nigatus, but tho lateral obliiiue 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 tho base of the mandible is also much greater. Calochromus velutinus. (Plate I. fig. 7.) Waterh., Cistula Ent, ii. 1877, p. 199. Elongatus, piceo-niger, supra piceo-testaceus, dense flavo-rufo- sericcus ; thorace sat transverso, medio canaliculate, utrinque for- titer impresso ; elytris obsolete bicostatis ; abdomiue cyaneo-nigro. Long. 5| lin. Uah. Burmah {J. C. Boivring, 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. ruhcr this space is quite equal to the diameter of the antennal pit. The third joint of the antennas is as long as tlie 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 tho 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 costoe, with an indication of a third. Calochromus segregatus. (Plate 1. fig. 8.) Depressns, cyaneo-niger ; thorace elytrisque ochraceo-rufis : 6 LTCIB^. thorace sat depresso latitudine paulo breviori, medio linea tenui im- presso; elytris striis plurimis. $ . Long. 4^ lin. Hah. Java {J. C. Bowring, Esq.). Most nearly allied to C. velutinus, but more depressed. Thorax above less uneven, the mesial line finer, the sides rather straighter ; the lateral ridge is less strong, a little more posterior, and very short. Scutellum red at the apex. Elytra nearly parallel, flat ; each elytron with about seven finely impressed lines, the interstices flat ; the extreme apex is bordered with black. Calochromus tarsalis. (Plate 1. fig. 9.) Niger, parallelus ; thorace transversim quadrato, lateribus rufis, baud marginatis ; elytris rufis baud striatis ; pedibus tenuibus, tarsis longis gracilibus. Long. 3^ lin. Hub. India.

Long. 5-6 lin. Hab. Penang (J. C. Boivring, Esq.). S . Antenna about two thirds the length of the elytra, moderately broad in the middle, tapering to the apex. Rostrum extremely short, the space between the antennal pit and the base of the man- dible about one third the diameter of the antennal pit. _ Thorax black, clothed with very fine silky-red pubescence, only visible in certain lights ; the discoidal channel rather deep, the lateral impres- sions deep and well-defined. ScuteUum black. Elytra clothed with bright red pubescence ; each elytron with two not very prominent costje. The underside and the legs black, scarcely tinged with blue. Penultimate segment of the abdomen emarginate. 2 . Antennae rather shorter and broader than in the male. Ros- trum a little more prominent ; the space between the antennal pit and the base of the mandible about half the diameter of the pit. CALOCHROMUS. Thorax reddish yellow, with the sides and the mesial line black. Each elytron with three distinct costoe, the apex broadly black. Var. 2 ' Thorax entirely red, the pubescence more dense. Elytra bicostate, the costae narrower. Calochromus lepidus. (Plate II. fig. 3.) Waterh., astula Ent, ii. 1877, p. 201. Caenxleus, nitidus ; thoraco vix brevissime pubescentc ; disco lon- gitudinaliter fortiter impresso, lateribus biimpressis ; elytris piceo- testaceis, dense fulvo-rufo-pubescentibus, striis vix perspicue im- pressis, apice anguste nigro ; antennis pedibusque violaceis. Long. 3|-4| lin. Hah. Java {6), Penang ( $ ) (J. C. 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 dcflexed, 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 fossfB are deep, but the oblique ridge which divides them is not so well defined as in most of the species. c? . AntenufE rather slender. Elytra with scarcely any trace of costse. Penultimate segment of the abdomen with a deep incision. 2 . Antenn?e 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 he associated as sexes of the same species. Calochromus longipennis. (Plate II. fig. 4.) Waterh., Cistula Frnt, ii. 1877, p. 201. Elongatus, subparallelus, niger ; thoraco supra piceo, dense rufo- pubescente, medio foveola lanceolata impresso, lateribus biimpressis ; scutello piceo, rufo-pubescente ; elytris longissimis, dense rufo- pubesceutibus, ad apicem nigris, costatis, costis angustioribus. 2 . Long. 6 J lin., lat. 1|- lin. Hah. Sumatra {E. C. Buxton., Esq.). Forehead evenly convex, black, very finely pubescent, rostrum about three times as broad as long ; maxillary palpi very stout. Antennte 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 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 uearly reaching from the aiaterior to the posterior margins, Elytra very long, with bright red pubescence ; each elytron with three not very distinct narrow costae, the outer one very obsolete. -^ There can be no doubt that Micromiclius bimaculatus, Motsch. (Bull, Mosc, 18G1, i. p. 138), from Ceylon, is closely allied to C. longipeimis. 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 costae are not so prominent as in C. longi- pennis. Section III. Intermediate coxm of the male ivith a strong spine ; base of the femur ivith a strong tooth ; tihice curved. Calochromus dispar. (Plate II. fig. 1.) Waterh., Cistula Ent., ii. 1877, p. 202. Cyaneo-niger, sat nitidus ; elongatus, parum convexus ; thorace marginato, medio canaliculato, utrinque biimpresso ; elytris rufis, dense pubescentibus, postice paulo ampliatis. (S . Long. 6 lin. Hab. Borneo {J. Bussell). 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 the base ; the intermediate and posterior tibiae strongly curved. The penultimate segment of the abdomen is deeply notched in the middle. DEMOSIS. Lycus (genus 4), Waterh., 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. Rostrum distinct but short. Thorax rather transverse, quadrangular ; the disk smooth, the mai'gins reflexed. Elytra flattened, subparallel, with moderately distinct costae, the intervals punctured. Demosis peltatus. (Plate II. fig. 5.) ParaUelus. depressus, piceo-nigcr ; thoracis limbo elytrisque flavis, his apice iiigris ; abdominis marginibus late flavis. Long. 3| lin. Hah. Lake N'Gami {Andersson) . Nearly parallel, the elytra very little wider than the thorax. Head and the basal joints of the antennte very slightly pitchy. Thorax nearly one tliird broader than long, yellow, shining aiid black in the middle : the sides subparallel, retlcsed, the posterior angles very slightly prominent. Elytra very finely pubescent, ■widest rather before the middle ; each elytron with four obtuse costa), 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 Lynis scrobicoUis of Fahraeus, and is the species referred to under " Genus 4 " at p. 97. I have, however, since seen a different species named L. scrobicoUis, one which in some respects agrees better with Flhraeus's description. It seems best therefore to consider the insect from Lake jNf'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. Thorax with a mesial impressed line, the margins thickened and narrowly reflexed. Each elytron with four costse, the fourth not elevated at the shoulder. Lipernes perspectus. (Plate 11. fig. 11.) Niger, nitidus ; thorace medio longitudinaliter impresso, margi- nibus anguste reflexis, angulis posticis acutis ; elytris thorace paulo latioribus, subparaUelis, testaceo-rufis, rugulosis, circa scutellum an- guste nigro-cinctis. $.

Nepal {Gen. Uardwicke), Allahabad and Siam (.J. C. Bow- ring, Esq.), Ceylon (Dr. Thwaites), Bootan {Dr. Pemherton). This species is very close to L. ferriujineus, F,, 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, Fabr. (Syst. El., ii. p. 110). L. mela- nurus, Blanch. (Voy. Pole Sud, iv. p. 74, t. 6, f. 2), and L. hivit- tatus, Kirsch (Mittheil. aus. d. k. zool. Museum zu Dresden, 1875, i. p. 34), are evidently synonymous with marginatus. Lycostomus aequalis. (Plate II. fig. 7.) Niger, subparallelus ; thoracis limbo, elytris abdominisque lateri- bus rufis. Long. 8 lin., lat. 3| lin. Hah. China {J. C. Bowring, Esq.). Closely allied to similis, Hope, but much more parallel in form. Antenna3 a little less slender than in that species. Kostrum a little shorter, and thicker at the base. Thorax broad, blackish in the middle. Elytra subparaUel, red, the costse nearly parallel ; at the posterior two thirds, the fourth costa is not further distant from the margin than it is from the third costa, the margin itself is more thickened. The fine pubescence which clothes the upper surface of the insect is more distinct than in similis and is golden red. LYCOSXOMUS. 11 Lycostomiis vulpinus. (Plate 11. fig. 8.)

Near L. similis, Hope, but the teguments are more delicate, the colour flesh-colour, and the thorax has the sides less reflexed. Eostrum reddish testaceous, a little longer than broad. Antennae rather shorter than in simiUs and less broad. Thorax with the sides moderatel}' reflexed, the posterior angles prominent and acute, the disk somewhat infuscated. Scutellum black, parallel at the sides, truncate at the apex. Elytra gradually but not much en- larged posteriorly, the sides rather straight, only arcuate near the apex ; the third costa is somewhat indistinct, the fourth is strong, and forms a strong well-marked carina over the shoulder, more ele- vated than in similis. Lycostomus modestus. (Plate II. fig. 10.) Niger, opacus ; thoracis lateribus elytrisque ferrugineo-rufis, regione scutellari angusto infuscato. Long. 6 lin., lat. 2^ lin. Hab. Bootan (Pemberton), India (Boys). Opaque above. Rostrum a little longer than its width at the base, narrowed towards the apex. Antennae narrow and linear. Thorax trapeziform; the disk flat, dull black; the sides reflexed, red. Elytra duU red, slightly wider at the apex ; each elytron with four equidistant costse ; the interstices with rough transverse reticu- lation ; the first, second, third, and fourth interstices with an indi- cation of an interrupted intermediate costa. (^ . Antennae a little more than half the length of the elytra, rather slender, all the joints elongate. 2 . Antennae half the length of the elytra, the eighth and ninth joints scarcely longer than broad, the tenth as broad as long. Lycostomus ambiguus. (Plate III. fig. 3.)

Rostrum moderate, about a quarter longer than its width at the base. Antennae rather slender, about half the length of the elytra. Thorax with the margins moderately reflexed, dull red, the 12 LTCIDJE. disk Mackish, the anterior and posterior margins narrowly bordered with red, the posterior angles acute. Scutellum black. Elytra dull red, gradually widening to near the apex ; each elytron with four costfE, the intervals roughly punctured, but with no distinct reticu- lation. Margins of the abdominal segments dull brick-red. 5 . Rostrum long and slender. Antennoe a trifle shorter than in the male. Thorax very broad, the margins broadly reflexed and expanded, the sides rectilinear, the posterior angles a little less than right angles, the disk more or less blackish. Elytra dull red. Ab- domen dull brick-red, blackish in the middle at the base. The two specimens above described as sexes are very dissimilar, but they have so much in common, besides the peculiar rusty-red colour, that there is little doubt that they should be associated as sexes. Lycostomus singularis. (Plate II. fig. 9.) Niger, opacus ; thoracis lateribus elytris(]ue ferrugineo-rufis. 5 . Long. 6| lin., lat. 2| lin. Hah. South India ( WaUiouse). Very close to L. modestus, but diflFers in having no black on the elytra near the scuteUum, and the sculpture of the elytra is much finer and without reticulation. Lycostomus niiiventris.

Thorax somewhat trapeziform, a little narrowed in front, pale red ; the disk black ; the margins broadly reflexed, the sides rectilinear, the posterior angles a little less thau right angles. Scutellum rod. Elytra somewhat parallel, rather pale red. Coxa3 and abdomen reddish. With the specimens above described are associated two other examples, which have the rostrum black, but do not differ mate- rially in any other respect, and may therefore safely be considered varieties.

This species is very close to L. internexus, but has the teguments rather more delicate, the colour is paler ; it is usually of a broader form, and the elytra are more ample, the sides posteriorly being more strongly arcuate. The antennge have the first three joints usually pale, but some examples have as many as seven pale joints. (S . Legs black, with the base of the femora pale. 5 . Legs yellowish, with the tarsi and sometimes the apex of the tibiae black. Mr. Walker's type of L. divisus is merely a small example of his L. planico7'nis: both are females. Lycostomus nigripes.

Legs black, except the base of the femora. $ . The foregoing description is taken from the original type in the Banksian collection. The specimen is said to come from Siam. There are three specimens in the British-Museum collection from Penang which agree very nearly with the Fabrician type, but the colour is more yellow, the thorax less regularly triangular, and the sides are not so suddenly reflexed. The male example is entirely pale below, with the apex of the posterior tibiae and the tarsi fuscous, and the apex of the elytra is black ; the two females have the elytra entirely yellow, the mctasternum and abdomen are more or less dusky, and the legs are blackish, with the base of the femora pale. Lycostonius placidus. (Plate III. fig. 7.) Ochraceus ; antennarum articulis 4*0-1 1"™, palpis, tibiis tarsisque nigris. Long. 4-7 lin., lat. lg-3| lin. Var. 1. Eemoribus apice uigris. c? , $ . Var. 2. Elytris apice nigris. d , 2 • Hah. Hong Kong {J. 0. Bowring, Esq.). Pale ochreous. The eyes, the fourth to the eleventh joints of the antennas, the tibioe, and tarsi black. Thorax narrowed in front, the disk somewhat shining. Elytra not much enlarged towards the apex, the sides rather straight, the humeral ridge not very strong. This species differs from L. nigripes in being longer in the elytra, which are also a little more parallel. The thorax varies immensely, but appears to be always relatively longer than in L. nigripes., and the disk is more shining. The legs are generally black, except at the base of the femora, but a small example has the femora almost entirely yellow. The specimens which have the apex of the elytra black are the largest specimens, and have the thorax broader than in those with unicolorous elytra : but the largest unicolorous specimen and the smallest example with black apex to the elytra agree so nearly in size and form that I cannot consider them distinct species. The specimens appear nearly all to have been taken together, and are marked by Mr. Bowring 25|7|50. The variety with the black apex to the elytra much resembles some specimens of L. analis, but may be distinguished by the rela- tively longer elytra (which are not so much arcuate at the sides), and by the form of the thorax, which is less trapeziform and less silky than in analis.

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 ( 5 ) of i. latlssimiis, in the Linnean collection. The variety L. harpago, Th., has the two lateral spots united by a fascia. Variety fenestratus, Murray, has this fascia and the black at the apex eon- 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 truucaturo 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 (Hev. Zool., 1847, p. 227) provisionally re- named the Fabrician insect Fahricii. 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 Jatissimus, 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. ampliatus, Fahr., and is almost certainly the male of the species which he names L. proboscideus* (Ent., ii. 29, p. 8, t. 1. f. 6). BEOXYLUS. 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 carinse. The species upon which this genus is founded closely resembles Calopteron dilatatum.

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. C. tricolor usually has the tibiae dusky, which is not the case in the specimen described as notatum ; but the species is very variable. Calopteron typicum. (Plate VI. fig. 1.)

Very close to C. 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 ' 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 hasi nigro," instead of " aj)ice nigro." It is C^XIA. — CELETES. 23 possible that divisum may be a variety of dorsale, but it is certainly not a variety of tyjyicum. Secondly. C. dorsale, Newm., is placed as a variety of reticulatum, Fabr. (Syst. Eut., 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. CMSlk. K'ezvm., Entom. Mag., 1838, v. p. 381.

The coxiB 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 tliose of other authors. I think, how- ever, that there is little doubt that alatus, N., is the female of lictor, N., corresponding respectively to timklus, Le C, and ceger, LeC, which, according to Dr. Le Coute 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.

Difi'ers from the three preceding species in having the punctua- tion of the strioB of the elytra less strong and more obscure, the in- terstices being a little less narrow, and all equal except the eighth, which is a little more elevated. The antennae have the branches to the sixth and seventh joints about as long as the joints. The usual short channel in the middle at the base of the thorax is scarcely noticeable.

The alter- nate interstices of the elytra are slightly costiform, the others are extremely narrow and somewhat obscured, and interrupted by the rather strong punctuation of the striae. Celetes scahripennis, Motsch. (Bull. Mosc, 1861, i. p. 137), belongs to this genus, and should come here. It is much smaller than any of the preceding (1|-2| lines long), and has the elytra pale yellow, with the apex black. The thorax has a fovea in the middle at the base, and is impressed on each side. The elytra have the striae rather more finely punctured than any of the preceding species; the alternate interstices are slightly elevated, the others are very narrow and somewhat interrupted by the punctures of the stri;e. The male has the branches of the antennal joints slender, a little longer than the joints themselves. The female has the antennae rather strongly serrate. The specimens in the Museum are from Ceylon.

Very close to D. scahnpennis., Mots., but the antennae, compared with the female, appear rather more dentate, the thorax is straighter at the sides, and the punctuation of the striae of the elytra is rather stronger and the interstices are all equal. DITUA. Rostrum none. Antennae broad, serrate. Thorax broad, a little more than a semicircle, the margins not incrassate, with a discoidal D 34 LYCIDiE. lanceolate areolet, from the lateral angle of which proceeds an ob- lique carina, which is scarcely noticeable. Elytra with nine regular nearly equal costae ; the interstices with a single line of punctures. Legs rather short. Thorax, elytra, and legs having a woolly ap- pearance. The form of the thorax and the presence of a mesial areolet sepa- rate this from the foregoing genera. Ditua deplanata. (Plate VIII. fig. 8.) Lvcus (gen. 20) deplauatus, Waterh., Trans. Ent.

Antennae broad, dentate. Thorax with the mar- gins incrassate, with a distinct discoidal areolet, united to the an- terior margin by a carina. Elytra with four distinct costae ; the interstices with two lines of punctures divided by a fine costa. Diff'ers from the preceding genus in having the margins of the thorax more or less reflexed and incrassate, and in the costae of the elytra being unequal. This genus was originally proposed for Lycus obsoletus, but three others are now associated with it. Bulenides obsoletus. (Tlate IX. fig. 1.) Lvcus (gen. 21) obsoletus, Waterh., Trans. Ent.

Fuscus, parum nitidus ; thorace fusco-testaceo, lateribus parum refiexis, disco utrinque fortiter impresso, antice carina brevi, medio areola lanceolata ; elytris basi plus minusve fusco-flavis, quadri- costatis, interstitiis biseriatim punctatis, seriebus basi costa tenui divisis. Long. ^ lin. Hab. Borneo. Thorax obscure testaceous, rather dusky at the base ; the carina is scarcely perceptible in front, and is divided posteriorly into two. Elytra parallel, fuscous, paler at the base ; each elytron with four di- stinct costfe, which turn slightly away from the scutellum near the base; the interstices with two lines of moderatelv strong punctures, the D 2 36 LYCID.M. lines divided at the base by a very fine carina ; the outer line of punctures has a tendency to encroach on the inner line, and towards the apex the lines are somewhat confused. It is doubtful to which sex the specimen described belongs. CAUTIRES. Rostrum none. Antennae of the male with a long compressed branch proceeding from the base of the third to tenth joints ; very strongly dentate in the female. Thorax with seven areolets, the two lateral ones sometimes obsoletely divided. Elytra as in Bulenides. The males of this genus are easily known by the branches of the antennal joints arising from the base of the joints. The females have the antennae very acutely dentate. Cautires excellens.

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.

Thorax somewhat transverse, rather strongly constricted before the posterior angles, which strongly diverge and are acute ; the mesial areolet is very broad, it nearly extends to the anterior and posterior margins, and is connected at the sides by an oblique carina on each side. The elytra have a reddish-yellow spot on the humeral angle ; each elytron has seven costae, the second, fourth, and sixth much stronger than the others ; the intervals have well defined transverse nervures which divide the surface into squares or only slightly transverse spaces. EROTIDES. Eostrum none ; forehead produced into a process between the antennae. Antennae simple ; the second joint smaU, but distinct. Thorax trapezoidal, with seven areolets as in Platycis minutus. Elytra parallel ; each elytron with four strong costae ; the interstices with transverse costae, which are placed somewhat close together, frequently oblique, or divided so as to form the letter Y placed horizontally -<.

Thorax rather broader than long, with the sides reflexed ; the surface is divided into seven areolets, the discoidal ones shallow, the lateral ones deep ; the three anterior carinas are parallel, the outer ones of these three are con- tinued posteriorly and curved somewhat in the form of reversed brackets )(, so as to enclose the posterior mesial areolet, which is closed posteriorly by the base of the thorax. The elytra are sub- parallel, each with four very weD-marked shining costae; the inter- stices have numerous rather less elevated transverse shining ridges, which are either straight, oblique, or divided into two halfway across the interstice.

It is difficult to decide whether Lycus rujipennis, F., should be considered identical with P. eri/thropteruni, Er., or with P. sale- hrosum, W. I have here adopted Erichson's view, by which the latter becomes synonymous with the Fabrician species. Metriorrhynchus haemorrhoidalis. Porrostoma hagmorrhoidale, Waterh., Trans. Ent.

This species resembles M. scalaris, but is much longer and nar- rower, and the rows of punctures on the interstices of the elytra are much more regular. Lycus atmtus, Fabr. (Syst.

The ridges which divide the thoracic areolets are very obtuse. In the British-Museum collection are several sptecimens of a species from Celebes which I have determined to be Lycus thoracicus, Fabr. (Syst. El., ii. p. 117), with which 31. eyanopterus, liedt., seems to be synonymous. M. jlavicollis drffers from these in having the elytra black, the thorax is more convex on the disk, the sides are less re- fiexed, 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 costoe has two lines of very close transverse punctures which meet in the middle of the interstice ; in Jlavicollis 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, Fabr. * (Syst. EL, ii. p. 112). The specimens in the Museum col- lection which I have determined to be the Fabrician species average a little larger ; the strong costse of the elytra are of equal thickness throughout, and the intermediate costse 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. Mrscliil in having the mesial areolet of the thorax more obtuse in front and more removed from the anterior margin ; the intermediate costae of the elytra are distinct and eqiial throughout their length. The base of the femora and the base of the tibise are yellow, as is also the sternum. Hah. Batchian. Metriorrhynchus rusticus. (Plate XIII. fig. 2.)

Long. 10 lin. Hab. Ternate, Batchian. This species is very distinct on account of the elytra being less parallel than iu any of the foregoing, slightly widened towards the apex. The transverse costse of the interstices of the elytra are extremely close and distinct, with the intervals between these eostae scarcely as much as the thickness of the eostae themselves. Abdo- men slightly bluish black. Metriorrhynchus philippinensis. (Plate XIII. fig. 4.)

Scutellum narrowed towards the apex, deeply but more narrowly excised at the apex. Elytra similarly sculptured to the preceding ; but the elytra being a little narrower, the inter- stices are narrower, and consequently the transverse costse are shorter. The abdomen and sterna are brighter steel-blue-black. Metriorrhynchus sericeus. (Plate XIII. fig. 5.)

Elytra with the interstices very silky, with closely set transverse costa3 ; the spaces between these costae rather less than the thickness of the transverse costae them- selves. The male example has the sculpture much obscured by the fine silky pubescence, which makes them appear more roughly punctured. Metriorrhynchus sericeus, var.

The basal third only of the elytra is yeUow, 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 31. ephippiyer, Gruerin (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. Metriorrhynchus nobilis. (Plate XIII. fig. 3.)

Elytra with the eight cost?e 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 cost® 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.)

Torres Straits, Batchian, Aru I. The thorax has seven areolets, but usually the mesial lanceolate one only is distinct ; the surface is rather roughly punctured, except the posterior part of the disk. Each elytron has eight costae, the alternate ones rather narrower and less elevated ; the punctures in the linos 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 diifer, 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).

Thorax with a lozenge- shaped mesial areolet, which extends from the base to the anterior margin ; from each lateral angle of this areolet there is a straight carina, which extends to the middle of the side ; by this means the surface is divided into five areolets. Elytra with four costae, the interstices irregularly punctured. This genus is proposed for the reception of a single Australian species. Synchonnus clientulus. (Plate XY. fig. 2.)

Hcib. Sumatra (Bti.rton). The male has the antenna^ only slightly more dentate than in the female ; they are rather broad, and of nearly equal width through- out in the typical specimen. 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 have, 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 antenna; broad, as in the type example. It seems best, at least for the present, to consider these specimens varieties of the same sjiecies. The example which I named M. velutiuus (Trans. Ent. Soc, 1878, p. 110) has the mesial areolet of the thorax black, and the antennae less robust ; but I believe this will prove to be a variety of C. signi- collis, Kirsch. Conderis major.

The first strong costa is joined by its two fine companions at not more than one-sixth the length of the elytra ; the punctures in the lines are generally square, but they are very irregular. There is a male example from Aru Island, which I think may prove to be distinct from T. niger ; the thorax is more I'ounded iu front, the posterior angles more diverging ; the elytra have the fine lines dividing the rows of punctures almost wanting, and the strong costoe are more developed.
