Mr. F. P. Pascoe on new Genera of Cerambycidse. 307 Darjiling. This species is a typical Diplommatina, with strong costulation and a well- developed columellar tooth. The animal is sketched as it appears just emerging from the shell. The eyes, as will be seen, are distinctly lateral, as in Cyclophoims. I can trace no difference between the animal of this form and that of the smooth or spirally ribbed species of the Indian peninsula, which are by Pfeiffer classed as Arinia, in the neighbourhood of Pupina, in a different family, and even a distinct suborder from their nearest allies the typical Diplom- matime. Central India, Feb. 1867. XLV. — Characters of some new Genera of the Coleopterous Family Cerambycidse. By Francis P. Pascoe, F.L.S., F.Z.S. &c. The eighth volume of the great work of Prof. Lacordaire being nearly ready for the press, I am desirous of publishing the fol- lowing descriptions of some new genera of the family to which that volume will be, with the Prionidse, entirely devoted, in order that they may take their place in that work, the plan of the author not permitting him to notice any genera which have not been published. These genera do not include several new forms discovered by Mr. Wallace in the Malayan Isles, which must unavoidably stand over for the ' Longicornia Malayana ' publish- ing by the Entomological Society. Chorothyse. ( $ ). Antenna breviusculse, 1 2-artieulat8e, scapo perbrevi. Elytra abbreviata, intra excavata. TibicB posticae elongatse, eurvatse, compressae. Abdomen breve, segmentis duobus basalibus multo majoribus. Head exserted, transverse anteriorly ; clypeus broadly emar- ginate. Eyes large, reniform. Antennae rather short, 12-jointed, a little thickish, distant at the base ; scape very short, obconic ; the third joint twice as long, the following gradually shorter, the last smaller and ovate. Palpi short, cylindrical. Prothorax transverse, broader than the head, rounded at the sides. Elytra short, hollowed out along the sutural margin, rounded at the apices. Legs unequal, anterior and intermediate short ; poste- rior tibia3 elongate, curved, and compressed ; tarsi short, narrow. Anterior coxae exserted, contiguous. Pro- and mesosterna very narrow. Abdomen short, the two basal segments much larger than the rest, the second and following excavated, the excavation filled with hairs. 23* 308 Mr. F. P. Pascoe on some new Genera of In a nearly allied genus, Psebium ^, the male has the abdo- minal segments nearly equal in length, and the antennse a little longer than in the female, in which they are about the length of the body; in the latter sex these organs appear to be twelve-jointed; the last joint, however, is simply notched in the middle; or per- haps it would be more correct to say that the last joint is anchy- losed to the preceding one. But in the present genus the twelfth joint is as distinct as any other, although smaller and somewhat differently formed. In other respects this genus differs from Psebium in its rounded prothorax, elytra hollowed out at the suture, and shorter antennse. With regard to the peculiar ex- cavation of the abdomen in the females of this and some other genera of Longicorns, nothing is known ; patches of hairs and other modifications of this structure are found also in some genera of the subfamily Obriinse, in Megaproctus (an anomalous African genus), in Cartallum, Penthea, and Sympkyletes ; in the latter the peculiarity is sometimes found in both sexes, but not always in the same species. The unique example of the curious insect described below was recently taken at Cape Town by Mr. Roland Trimen. Chorothyse vesparia, C. nigra, antennis, elytris, tibiis tarsisque Isete fulvis. Hub, South Africa. Head and prothorax black, opake, finely and closely punctured, clothed with rather longish erect hairs ; scutellum black, gla- brous and shining at the apex; elytra clear fulvous, shortly pubescent, not extending beyond the posterior coxse; abdomen and femora black, with loosely set longish hairs, the excavated portion of the former with close-set fulvous hairs ; tibise and tarsi clear fulvous, the former with longish yellow hairs. Length 6 lines. Nephithea. Frons convexa, baud sulcata, inter oculos quadrata. Prothorax subcylindricus, postice attenuatus. Elytra abbreviata, alse quam abdomen breviores. TibicB posticae elongatae, lineares. Head exserted, the front convex and quadrate between the eyes, no groove above the epistome. Antennary tubers oblique, well marked anteriorly, contiguous at the base. Eyes narrow, roundly emarginate. Antennse imperfect; the scape rather short, obconical; third, fourth, and fifth joints about equal, each of them twice as long as the scape; the rest wanting. Prothorax narrower than the head, subcyhndrical, from about the middle * Pascoe, Joum. of Entom. ii. p. 289. the Coleopterous Family Cerambycidse. 3Ut^ gradually narrowing to the base. Elytra abbreviated, hollowed out along the sutural margin ; the wings not extending to the last abdominal segment. Legs unequal; anterior and inter- mediate pair very short; posterior much longer, their tibiae linear and twice the length of the anterior ; tarsi very short, all of nearly equal length. Anterior coxae conical, contiguous. Ab- domen depressed, its segments nearly equal in length. This remarkable insect has been for years in my collection ; but, notwithstanding its imperfect condition, I am desirous that it shall find its place in M. Lacordaire's work. It is evidently allied to Psebium and Chorotliyse^ especially to the former, but in the form of the head is different from either. Nephithea necydaloides. N. cyanea, elytris griseis; antennis, scapo excepto, pedibusque nigrescentibus. Hab. Natal. Dark blue, tinted with violet, the abdomen especially with short stiffish grey hairs; head and prothorax closely punctured; scutellum triangular, black ; elytra pale grey at the base, darker posteriorly, scarcely extending to the end of the second abdo- minal segment, finely punctured, each with two slightly raised lines; body beneath violet, with a thin greyish pile; antennae and legs blackish, the femora with a bluish tint. Length 4J lines. Demomisis. Oculi integri, rotundati, laterales. Antennce breviusculae, scapo vix elongato, clavato ; art. tertio sequen- tibus (quarto excepto) baud longiore. Elytra linearia, normaha. Coxce anticae exsertae, globosae, approximatae. Head nearly quadrate in front, not prolonged into a muzzle. Eyes entire, rounded, placed at the sides beneath the insertion ot the antennae. Antennae rather short ; the scape clavate, not extending beyond the middle of the prothorax ; the third and following joints shorter and more or less of nearly equal length, the fourth being the shortest. Prothorax narrower than the head, elongate, constricted before the middle. Elytra very narrow, linear. Feet rather short; femora fusiform; tibiae slender, straight ; tarsi with the first joint scarcely so long as the rest together. Anterior coxae large, exsertcd, nearly globose, approximate. Pro- and mesosterna very narrow. This is a very remarkable form, allied to Rhagiomorpha, from which it is at once differentiated by its entire eyes, — and more remotely to Psilomorpha and Sylliius, but with antennae essen- 310 Mr. F. P. Pascoe on some new Genera of tially dissimilar. In the case of the eyes, the upper lobe entirely disappears; and it is worthy of remark that in the subfamily* to which this insect belongs there has as yet been found no in- termediate form of eye : it is either normal or at once reduced to a single, and always lower, lobe. Demomisis filum. D. rufo-brunnea J elytris costulatis, interspatiis punctis seriebus duabus instructis. Hab. Western Australia (Champion Bay). Reddish brown, bases of the joints of the antennae and tibiae paler; head finely and sparsely punctured, a groove on each side between the eye and the mouth ; prothorax finely corru- gated transversely ; scutellum large, triangular ; elytra with four elevated lines on each, the second and fourth united near the apex, the intervals with two rows of coarse punctures at the base, but uniting to form a single row posteriorly ; body beneath dark brown. Length 3 lines. ZORION. Caput pone oculos sensim attenuatum ; oculi parvi, profunde emar- ginati. ^ Prothorax basi apiceque constrictus, postice tenuior. Femora abrupte clavata. Head somewhat quadrate, transverse in front ; the antennary tubers prominent, rising gradually from each side of the mesial line. Eyes small, deeply emarginate, finely granulate. Antennae as long as the body, linear, distant at the base ; the scape cylin- drical and longer than any one of the other joints ; the third, fourth, and fifth nearly equal, the rest gradually shorter. Pro- thorax narrower than the head, deeply constricted at the base and apex, the posterior very much narrower than the anterior portion, the sides angulated at the middle. Elytra short, obo- vate. Legs increasing in length from the anterior to the poste- rior; femora abruptly clavate; tibiae slender; tarsi of nearly equal length, not dilated. The type of this genus is Callidium minutumj Fab. (Syst. Ent. p. 192, 1775). Prof. Westwood has since described a second species, under the name of Obrium guttigerum (Arc. Ent. ii. p. 25). * Having recently obtained a male example of Diotima allied to, or possibly identical with, D. lindulata, and belonging to the same subfamily, I may mention here that the antennai are much longer than the body, and nearly twice as long as in the female, and that they are, moreover, twelve- jointed. 1 have also a female specimen, from Clarence River, scarcely more than half the length of the specimen described by me, and which seems by its characters to belong to yet another species of the genus. the Coleopterous Family Cerambycidse. 311 The former is a glossy testaceous insect, with a round bright- yellow spot on each elytron, and the bases of the femora white ; it is about 2J lines long. Both species are from New Zealand. I refer the genus to the Stenoderinse, which for me provisionally comprises a series of anomalous forms, mostly Australian, frag- ments perhaps of a once larger group, but which might, and probably will, be divided into almost as many subfamilies as there are genera. Beyond their anterior contiguous conical coxae, they have scarcely any characters in common ; but they have often a petiolate abdomen, and antennae never inserted beyond the eyes; and these characters will to a certain extent generally distinguish them from the allied subfamily Lepturinse. The only European genus belonging to it is Molorchus^, OSSIBIA. Antenna setaceae. Oculi magni, infra contigui. CoxcB anticae globosae. Head transversely ovate in front, without a groove above the epistome. Eyes very large, contiguous beneath. Antennse seta- ceous, 11-jointed, longer than the body; the scape short, cla- vate ; third joint shorter than the scape, the fourth to the sixth or seventh gradually longer, the remainder equal. Prothorax elongate, subcylindrical. Elytra parallel. Anterior coxae glo- bose. Legs gradually longer posteriorly ; femora claviform ; tarsi linear, posterior with the basal joint as long as the two * This genus was founded by Fabricius (Ent. Syst. i. 2. p. 356) on the Necydalis major, Linn. The name Necydalis was first appHed by Linnaeus, in his 'Iter (Elandicus,' to N. minor; but it was only in the 12th edition of the * Systema Naturae ' that he characterized it, when N. major took precedence. We have therefore, if we take the first species of a genus, when it is first published, as the type, two generic names given to one species. But it has always appeared to me a mistake to apply such a rule to any of the Linnean species, nor has it been usually done ; for example, the type, so called, of his Leptura is now a Donacia, of Ceramhyw an Acrocinus ; so of Scarabaus, Cantharis, Tenebrio, Carabus, Elater, and others, in all of which the first species has received a new generic name. Now the Linnean characters of Necydalis are of the most shadowy kind. Here they are : — "Antennae setaceae. Elytra alis minora, breviora s. angus- tiora. Cauda simplex." The last seems to have been intended to sepa- rate it from the earwigs. On the other hand, Fabricius's description of Molorchus is evidently only taken from M. major, the first species, as was invariably his rule in the ' Ent. Syst.' Had he had N. minor before him, he would not have said "antennis thorace longioribus " for an insect in which those organs were twice the length of the body. The formula of Linnaeus, then, applying to anything (the greater part of his species are, in fact, heteromerous), and the Fabrician description applying strictly to major and not to minor, it seems to me that Molorchus sliould be confined to the former and its congeners, and that Necydalis should be used for the species to which the name was originally applied. 312 Mr. F. P. Pascoe on some new Genera of next together. First abdominal segment not twice as long as the second. The type of this genus has long been known as the Obrium fuscatum of Dejean^s Catalogue ; but, if we except the elytra and legs, all the above characters are at variance with that genus*. I may add that the maxillary palpi are very short compared to those of Obrium, the second and third joints especially so. Ossibia fuscata, O. fuscescens, elytris viridi-piceis, sutura testacea. Hab. Senegal. Pale brownish, thinly pubescent, with scattered stiffish hairs ; head brownish red ; eyes black ; prothorax vaguely punctured, a little tuberculate on each side at about the middle ; scutellum small; elytra covered with shallow scattered punctures, the suture testaceous, the sides pitchy, with a greenish tinge ; body beneath and femora reddish testaceous ; tibiae, tarsi, and antennae brown. Length 4 lines. NiDA. Antennne art. quarto quam tertio vel quinto breviore. Prothorax elongatus, subcylindricus. Mesothorax elongatus, mesosterno angustato. Head short in front. Eyes moderate. Antennae longer than the body, the fourth joint shorter than either the preceding or following one. Prothorax elongate, subcylindrical. Elytra narrow, nearly parallel at the sides. Legs scarcely elongate, the femora strongly clavate. Mesosternum narrow ; mesothorax elongate. The principal characters differentiating this genus from Rho- palophora are the greater length of the mesothorax (by which the intermediate legs are placed at a considerable distance from the anterior pair), the narrowness of the mesosternum, and the nearly cylindrical prothorax. The habitat of the genus is ex- ceptional, all the Rhopalophorce and their allies being natives of the New World, with the probable exception of CleomeneSj J.Thomson. Nida flavovittata. N. nigra, elytris vittis duabus flavis omatis. Hab. Pegu. Black; head clothed with longish, white, scattered hairs; pro- thorax closely, and even confluently punctured, a few whitish hairs on the disk, with a somewhat semilunar or C-formed white * For the best definition of Obrium at present, ' see Fairmaire, ' Gen. de Cdleopt. d'Eur.' iv. p. 179. the Coleopterous Family Cerambycidse. 313 mark composed of densely packed hairs on each side ; scutellum also covered with white hairs ; elytra finely and closely punc- tured throughout, and clothed with scattered stiffish hairs, a broad and very distinct pale-yellow stripe on each side of the su- ture from the base to the apex, but not extending to rtie ex- treme of either, nor meeting at the suture ; body beneath black, with a whitish tomentum, thicker and forming a large patch on each side of the three basal abdominal segments ; femora glossy black, with long whitish hairs increasing in density on the tibise and tarsi -, antennse with a whitish pubescence. Length 5 J lines. Nyphasia. Pr other ax irregularis, lateraliter inermis. Femora petiolato-clavata, apicibus constrictis. Processus interfemoralis latus, antice rotundatus. Head exserted, very short in front, the clypeus separated by a deep groove below the antennary tubercles, the latter very large and protuberant. Antennse about as long as the body; the scape pyriform ; the third to the sixth joint spinous at the apex, the fourth shorter than the third or fifth. Pro thorax rather longer than broad; the disk and sides irregular, the latter unarmed. Scutellum narrowly triangular. Elytra gradually narrowing from the base to the apex, the latter mucronate. Legs rather long; femora petiolate-clavate, their apices con- stricted; tibise slender; tarsi gradually increasing in length from the anterior pair. Pro- and mesosterna depressed. Pos- terior coxye not approximate. Interfemoral process broad, and rounded in front, not extending beyond the coxae. Although unlike Cordylomera in general appearance, I have been unable to find any reliable character to separate it except that of the interfemoral process, which in that genus is very narrow and pointed, and consequently the posterior coxae are approximate and, it may be added, more than usually exserted. There is no appearance of pubescence on the specimen described below, which has evidently been in spirits, and it may therefore have been obliterated. Nyphasia torrida. N. rufo-fulvescens ; antennis art. tertio ad sextum nigris ; scutello genibusque fuscis. Hab. Ceylon. Reddish fulvescent, opake; third to the sixth joints of the antennse black, tips of the remainder, except the last two, blackish ; scutellum and tips of the femora, with the bases of the tibise, brownish ; head and prothorax closely and finely punc- tured, the latter with a transverse depression anteriorly and a 314 Mr. F. P. Pascoe on some new Genera of callosity on each side of the disk at the base ; elytra covered with numerous small punctures, each elytron with two fine slightly raised lines ; body beneath and legs brownish luteous. Length 7 lines. Ipothalia. Antenna breves, incrassatae, serratae, art. quarto et quinto obeonicis, cseteris dilatatis, ultimo ovato vel triangulari. Prothorax lateraliter tuberculatus. TibicB anticae et intermediae spinis duabus minutis terminatae. Head anteriorly and mandibles moderately produced. An- tennae short, gradually thickened from the third to the seventh joint, the remainder, except the last, about the same size, and, including the sixth and seventh, dilated, especially on one side ; the second short, the third more than twice the length of the two following, the last ovate or triangular, flattened on one side. Prothorax rather longer than broad, stoutly tuberculate on each side. Elytra rather small, a little depressed. Posterior femora abruptly clavate. Anterior and intermediate tibiae terminated by very short spines. The other characters are pretty nearly the same as are common to the more normal Callichrominae ; the scutellum, however, forms a nearly equilateral triangle, with its two sides a little rounded, and its apex presenting a sort of prolonged appendage, especially evident in /. femorata. One of my species appears to be a male, the other (/. pyrrha) a female. If so, there will be no difference in the antennae of the two sexes. Ipothalia femorata. I. cyanea, nitida, prothorace viridi ; femoribus, basi excepta, laete luteis. Hah, Philippine Islands. Rich (rather dark) blue ; prothorax green ; head very sparingly punctured, a deep groove in front of each eye, terminating below in the transverse groove above the clypeus ; prothorax smooth, very minutely punctured ; elytra finely punctured, the punctures crowded, but not coalescing; body beneath blue, meso- and metathorax covered with a silvery pubescence; femora, except at the base, bright luteous ; tibiae blue, tarsi tinged with blue ; antennae entirely blue. Length 6 lines. Ipothalia pyrrha. I. cyanea, elytris viridescentibus, medio antennarum pedibusque laete luteis. Hah. Pegu. Dark blue ; elytra dark bluish green ; head minutely and the Coleopterous Family Cerambycidae. 315 closely punctured, facial grooves as in the last; prothorax transversely corrugated ; elytra finely punctured, the punctures everywhere coalescing and giving the surface a shagreened ap- pearance ; body beneath glossy blue, the posterior part of the prothorax, meso- and metathorax, and first abdominal segment covered with a silvery pubescence ; legs entirely bright luteous ; scape and second joint of the antennae purplish-blue, the five following joints luteous, the five remaining dark brown, opake. Length 7 lines. BlXORESTES. Antenna subincrassatae, lineares, art. muticis. Prothorax depressus, lateraliter angulatus. Head somewhat squarish in front, the muzzle broad and slightly produced. Eyes narrowly emarginate. Antennae short, thickish, linear; the third joint longest, the fourth to the seventh shorter and nearly equal, the eighth, ninth, and tenth gradually shorter, the last ovate and a little longer than the preceding joint. Prothorax depressed, with a strong angle in the middle on each side. Elytra rather broad, flattish above, closely em- bracing the abdomen. Femora fusiform ; posterior tibiae and tarsi elongate. The type of this genus is Clytus doctus, White (Cat. Long. Brit. Mus. p. 267) ; but it dificrs essentially from all true Clijti in the form of the prothorax. Mr. White says that it is allied to Clytus Hardwickii, from which nevertheless he separates it by ninety species. To me it is thoroughly distinct from anything I know. Bixorestes doctus is a reddish-ferruginous species, roughly punctured above, with six very bright yellow spots on the elytra, besides two less highly coloured spots at the base. It is probably from the Cape, as a nearly allied species in M. Chevrolat^s collection in the British Museum is so labelled. My specimen was obtained from a Paris dealer, who was ignorant of its habitat ; nor was Mr. White acquainted with the locality of his type. Ceramhyx interruptus, Olivier (Coleopt. iv. no. 67. p. 35, pi. 17. fig. 133) appears to belong to this genus. Its locality is also unknown. Thranodes. Caput antice tricarinatum. Antennce breves, claviformes. Prothorax globosus. Elytra plaiiata, abdomen baud tegentia- Head rounded in front, three vertical carinae between the eyes, the latter prominent, slightly emarginate. Antennae not half so long as the body, claviform ; the scape short, not so thick as the 316 Mr. F. P. Pascoe on some new Genera of terminal joints, the second half as long as the third, and from this they gradually increase in thickness to the eighth or ninth. Prothorax globose. Elytra flattish above, narrowing posteriorly, not bent down at the sides except at the base. Legs of moderate length; femora fusiform. Separated from Clytus and allied genera by the form of the elytra, which, consisting mainly only of the disk without the deflected sides, except a little near the shoulders, do not embrace the abdomen. The claviform antennae are less peculiar, being found also in Mecometopus and Rhopalopus, and in a much less degree in Neoclytus, CalanthemiSj &c. The type is Clytus steno^ thyreus (Pasc. Journ. of Ent. i. p. 359), from Batchian. I have another species from Tondano. In this the female differs only in having a more globose prothorax. The following genus was proposed by myself in the ' Journal of Entomology,^ ii. p. 246. As the characters by which it is differentiated from Aridcms, J. Thoms., were alone given, I take this opportunity of repeating them, with additions, in a more formal manner. Cremys. Antennce muticae, setaceae. Prothorax globosus, basi constrictus. Femora baud clavata. Head transverse in front, a slightly elevated line between the eyes terminating in an arched groove above the epistome. Eyes of moderate size. Antennae setaceous, unarmed, the fourth joint shorter than either the preceding or following. Prothorax glo- bose, strongly constricted at the base. Elytra short, rounded at the apices. Legs, except the anterior pair, elongate, the femora slightly fusiform. The rest as in Aridmis, The type, Cremys diophthalmus, Pasc, op. cit. i. p. S5S{Clyttis), is of a rich reddish-brown colour, with the apical half of the elytra black and covered with a shot-silky pubescence, and two black spots on the prothorax. It is from Queensland. Note. — I have been sharply criticised in a foreign work for declining to adopt the new genera formed at the expense of the old Fabrician genus Clytus. Whilst admitting that I have since gone with the stream, my objection was grounded on the fact that a few species only were selected as the types of new genera out of numerous others, many of which it then became very difficult to locate. I have some fifty unpublished species, and, so far as I can see at present, many of them have such neutral characters that it will be very difficult to assign them to well-de- fined genera. The three Clytoid genera described above have very marked and, in the first two of them, isolated characters. the Coleopterous Family Cerarabycidse. 317 Thoris. Prothorax oblongus, irregularis, lateraliter tuberculatus. Femora petiolato-clavata ; tarsi breves, longitudine fere aequales. Head exserted, short in front ; upper lip very small ; eyes broadly emarginate. Antennae ( $ ) shorter than the body ; the third joint nearly twice as long as the fourth and fifth together, these three with a short spine at each of their apices. Prothorax oblong, somewhat depressed, irregular, the sides tuberculate. Elytra rather short, parallel, the apex of each emarginate, with the outer angle spined. Legs gradually increasing in length to the posterior; femora petiolate-clavate ; tibiae slightly com- pressed ; tarsi short, nearly equal in length. Pro- and raeso- sterna simple. In habit this genus bears only a very slight resemblance to Callirhoe ; nevertheless I have found it difficult to diflferentiate it by any important character, except that of the short and nearly equal tarsi. It is probable that the antennae of the male, which is unknown to me, will afford other characters ; those of the female are shorter than the body, the apical spine, which is very small, disappearing at the sixth joint, and all the joints beyond the third are unusually short. The puncturation of the elytra is quite different from that in Callirhoe or Phoracantha. Thoris ehurifera. T. rufo-lutea ; elytris maculis flavis impunetatis decern ornatis. Hab. Rockhampton (Queensland). Reddish luteous, with scattered erect hairs; head finely punc- tured, a sharply impressed longitudinal line in front terminating in an arched groove above the clypeus; prothorax opake, mi- nutely punctured, the disk with five nearly obsolete tubercles, the central one excepted; scutellum hairy, rounded behind; elytra thickly punctured at the base, the punctures passing in- definitely into the surrounding derm, and gradually becoming less frequent posteriorly ; on each elytron five round w^ell- niarked yellow spots, a little raised and entirely without punc- tures, the first, fourth, and fifth spots on the same median line, the third nearer the suture, the second smaller and towards the side; body beneath, legs, and antennae chestnut-red, shining, covered more or less with greyish hairs. Length 5 lines. Brototyche. Prothorax subquadratus, lateraliter inermis. Coxce anticae approximatae ; prostermim carinatum. Processus interfemoraHs obtectus. Head small ; antennary tubers prominent, the upper margin 318 Mr. F. P. Pascoe on some new Genera of Cerambycidse. produced into a short tooth. Eyes broadly emarginate, incurved behind. Antennae ( ? ) about as long as the body ; the scape subpyriform ; third joint nearly twice its length, the remainder much shorter than the third, and of nearly equal length. Pro- thorax subquadrate, small, the sides slightly rounded and un- armed. Elytra parallel, the apices rounded. Legs rather slen- der ; femora moderately clavate ; tarsi unequal, the anterior with the three basal joints broad and of nearly equal length viewed from above, the intermediate and posterior with the basal joint longer, especially the latter. Anterior coxse approximate ; the prosternum narrow, crowned with a raised longitudinal line. Posterior coxse large and approximate, concealing the interfemoral process. This genus appears to be allied to Anoplistes, Serv., but is clearly distinguished by its narrow prosternum and large ex- serted and approximate posterior coxse, entirely concealing the interfemoral process. The elytra are also costulate, as in the cognate genus Tragidion, I am indebted for my specimen to Arthur Adams, Esq., R.N., who procured it during the survey- ing expedition of H.M.S. 'Actseon.' Brototyche Adamsii, B. nigra ; elytris sanguineis, singulis tricostulatis. Hab, Chosan (Japanese Sea.) Black ; head and prothorax crowded with small punctures and sparsely clothed with a loose rusty-grey pubescence ; scutellum triangular, black ; elytra finely pubescent, pure blood-red, each with three well-marked raised lines, terminating before the apex; body beneath, legs, and antennse black, with scattered rusty hairs ; tarsi beneath silvery white. Length 8 lines. Thephantes. Antennoi in medio incrassatae. Prothorax ovatus, subdepressus. Femora abrupte clavata ; tarsi postici art. basali triangulari. Head very transverse in front. Eyes large, broadly emar- ginate. Antennse shorter than the body; the scape rather short, clavate; none of the succeeding joints longer, but the third, fourth, and fifth nearly as thick as the scape. Prothorax shortly ovate, scarcely broader than the head, a little depressed, the sides irregularly rounded. Elytra parallel, depressed, rounded at the apex. Legs nearly equal ; femora abruptly clavate ; tarsi somewhat dilated, the basal joint of each short and more or less triangular. Pro- and mesosterna declivous. I am unable to say whether my specimen of this insect be Mr. J. Miers on the Menispermaceae. 319 male or female ; if the latter, the antenna? of the male may differ considerably ; but it is, without doubt, allied to Phacodes, Newm., in which genus the variations in the characters furnished by those organs are very disagreeable to the systematist. Thephantes clavatus, T. fuscus, pube grisea, albeseente vage intermixta tectus; capita prothoraceque subferrugineis. Hab, Darling Downs (Australia). Dark brown, covered with a rather coarse and loose greyish pubescence, indefinitely mixed with small spots of whitish ; the head and prothorax somewhat ferruginous, the upper surface with small dispersed punctures, those on the elytra nearly dis- appearing posteriorly and furnished each with a stiffish erect hair ; second and third joints of the antennae equal, shorter than the scape, the succeeding about the length of the scape; femora exceedingly clavate ; legs with longish hairs. Length 7 lines. ZOODES. Scapus brevis, pyriformis. Prothorax convexus, transversus, postice angustior, lateraliter baud excavatus. These characters appear to me to cut this insect off from Stromatium, to which Mr. White has doubtfully referred the only known species, Stromatium ? maculatum (Cat. Long. Brit. Mus. p. 301, pi. 8. fig. 4). The name adopted is a manuscript one, under which it stands in M. Chevrolat's collection. The following names applied to genera of the Cerambycidse I have changed, as they had been previously used in other groups : — TrichophoruSjSen?., non Temminck (Turdidae) : name proposed, Crocidastus. Petalodes, Newm., non Wesmael (Braconidae) „ Anatisis. Couothorax, J. Thorns., non Jeckel (Curcuhonidae) „ Massicus. XL VI. — On the Menispermaceae. By John Miers, F.R.S., F.L.S., &c. [Continued from p. 197.] 45. Pachygone. The existence of several genera among Menispermaceae with exalbuminous seeds was not known to botanists until I first in- dicated the fact in this genus, which was established in 1851; for it was then doubtful whether the genus Spirospermum
