VIACtGIO di LEONARDO FEA IN BIRMANIA E REGIONI VICINE LVI. A Lisi of tlie Longlcorn Coleoptera collected by Signor FEA in Burina and the adjoiniDg regioDs , with descriptions of the new Genera and species by CHARLES J. GAHAN, M. A., of thc 8ritish Musciiiii (Nat. History). {Piale J). The Longicorn Coleoptera recorded in the following list amount to a total of about 240 species. Of this number 90 are now described for the first time and, with 3 previously described by D."" Gestro, give 93 as the number of new species contained in the collections made by Signor Fea. But of these not a few were already represented in other collections by specimens which had been brought from Burma, or, as was more often the case, from North India. Where it seemed desirable, as ten- ding to throw some light upon the distri])ution of the species, I have added after each the other localities from which it was known, in addition to those indicated by Signor Fea's specimens. A comparison of these localities will show that the Longicorn fauna of Burma has very much in common with that of Nepal, Sikkim and Assam in Northern Hindostan. This is more parti- cularly true, perhaps J of mountain species, some of which range as far soutli even as Sumatra and Java. There is less resemblance between the Longicorns of South India and Burma, though a few species are common to both which have not so 6 e. J. GAHAN far been recorded from Nortli India. Among- the species that appear to be confined to Burma may be more especially men- tioned those of the fine genus Arclolamia described by D/ Gestro, and some large species wliich I iiave placed in the genus Niphona. Fea's collections have furnished tw o species of Atimura, one of which is indistinguishable from an Australian species described by Pascoe. Of the remaining species of Atimura two are from the Malayan region, and one from Japan. It is pro- bable that this genus is represented by a much larger number of species, but that owing to their small size and the protection afforded them by their great resemblance to little bits of sticks they have to a great extent escaped the notice of collectors. The new species, for which I have proposed the genus Estigme- nida, is also remarkable for its striking resemblance to a com- mon Oriental Hispid Estigmena chinensis, Hope. The majority of the new species belong to the groups Clytinae , Mesosinae, Ni- phoninae and Obereinae , and it may be found that, owing to their small size and the difficulty of identifying species in these perplexing groups, some of them have already been described. In identifying some of the more difficult members of the group Callichrominae I was indebted to the late M."* Bates for his usual kind assistance. While to M."" Pascoe and to M.'" René Oberthiir I have to render thanks, for the facilities they gave me in examining types from their collections. PRIONIDAE. 1. Cyrtognathiis (Baladeva) Walkeri, AVaterh., Trans. Ent. Soc.

Pascoe's collection by a single specimen from Sylhet. This specimen does not differ by any very important characters from the unique type of Aegosoma 8 e. .1. GAHAN White (Megopis) fLongic. Brit. Mus. pi. costipenne. , p. 28, 2, fig. 2) whicli also came from Sylhet in Assam. The question as to vvhetlier these differences are specific or merely individual must, however, be left in abeyance. It can only be settled by the examination of a larger series of examples. 12. Cyrionops punctipennis. White, Cat. Long. Brit. Mus., p. 32, pl. 2, fig. 3 (9).

In the single example taken, the front and the upper side of the head are dark l)rown ; and the small prothoracic spines are somewhat more distinct than in the other examples of T. calli- dioides that I have seen. It ought perhaps to be referred to T. nigriceps, Pasc, JDut the characters (with the single exception of the colour of the head) by which M."" Pascoe has distinguished the latter species do not well apply to the present variety. 14. Tetraommatus insignis, sp. n. [PL I, ^g. 1). Ferrugineo- teslaceiis, sparsim pubescens; prolhorace antice posticeque transversim sulcata, sulcis infuscads , lateraliler ulrinque tuherculo parvo acuto armato, basi constricto; dorso prope basin longitudinaliter hand profunda bisulcato: elytris dense pimctalis, Jlavo-testaceis, pone medium plaga fusca signatis; corpore subtus pedibusqtte nonnihil piceo-rufescentibus. Long. 10-11 mm. Thagatà ia Tenasserim ; one example. The British Museum collection contains examples from the Andaman Islands. Head and prothorax dull ferruginous-red. The length of the prothorax to its median breadth in the ratio of 3 to 2. The prothorax is closely but somewhat obscurely punctured ; its sides are slightly rounded, and each is armed with a small but sharp and distinct tubercle ; the constricted basal part of the protho- LONGICORN COLEOPTERA FROM BURMA y rax is preceded by a slightly arcuate transverse groove ; there is a feebler groove close to the anterior margin , and on the posterior part of the disk there are two shallow longitudinal grooves which pass in front into a Inroad sliallow longitudinal depression. Both the transverse and longitudinal grooves are more or less infuscate. Scutellum testaceous. Elytra thickly punctured ; yellowish-testaceous, with a brownish patch, formed by two oblique bands which pass outwards and backwards from the suture on each side between the middle and posterior third, and by the dark borders of that portion of the suture which lies between these bands: the posterior bands are short, the anterior bands extend farther outwards, and, near tlio margin, take an almost directly transverse direction. 15.

Bowring informs me) obtained at Hong Kong or its immediate neighbourhood. 20. Hoplocerambyx spinicornis, Newm. — flammaticherus spi- nicornis, Newm., The Entomologist I (1842) p. 245. Thagatà in Tenasserim ; one male example. This species oc- curs also in the Philippine Islands (type) in — ; and North India Allahabad and Nepal (Brit. Mus. collection). Examples from Borneo, constituting the //. morusus of Pascoe, do not seem to me to offer any definite characters by which they can be distin- guished from the above.
