Longicornia Malayana. 563 



latitudine haud longiore. Elytra angustata, ab- 

 domine breviora^ epipleuris nullis. Pedes attenuati; 

 femora vix clavata ; iihioB posticge compressas, arcuatse ; 

 tarsi postici breviusculi. Coxae anticae cylindricae, 

 haud contiguae. Mesosternum latum, antice abrupte 

 declive. Corpus parallelum. 



A Ceylonese species {T. gibhosus) is the type of this 

 genus, the species of which are found as far south as 

 New Guinea. * The males have not been known 

 hitherto ; one, however, of that sex, if I am not mistaken, 

 is described below, and differs very little from, but is, 

 perhaps, a little nari'ower than, the female. M. Lacor- 

 daire suspects that Olivier's Necydalis nigricornis (No. 74, 

 pi. i. f. 8) is congeneric ; I believe, however, that I have 

 identified this with a common South- African insect allied 

 to Phytoecia. f None of the species here described have 

 that gibbosity of the prothorax which distinguishes the 

 type ; all, except T. basalis, have a large white ring on 

 the antennae ; of the remainder T. angustipennis has de- 

 hiscent elytra; T. bimaculatus has a pale transverse spot 

 on the middle of each elytron, while in T. brunneus the 

 elytra are unicolorous. 



Thranius bimaculatus. 



Pascoe, lib. cit. p. 23, pi. ii. f. 7. 



T. fuscus ; elytris confertim punctatis, haud granulatis, 

 fulvo-brunneis, singulis in medio macula ochracea; 

 antennis articulo tertio toto fusco. 



Dark brown, head and prothorax with a dull gray 

 pubescence; the latter slightly transverse, granulate- 

 punctate ; scutellum triangular, brown ; elytra closely 

 punctured but not granulate, on the middle of each a 

 round ochraceous spot ; abdomen reddish-brown, with a 

 short gray pubescence; legs entirely dark brown; an- 

 tennae dark brown, the eighth, ninth, and tenth joints 

 pale yellowish. 



Length 10 lines. 



* M. Lacordaire (Gen. viii. 470), by a slip of the pen, says they are 

 proper to Australia. No species, to my kuowlege, is from that region. 



f For this I proposed the generic name of Dirphya, (Tr. Ent. Soc. ser. 

 2, iv. 262), but about the same time (later, I believe,) M. Thomson de- 

 scribed his geuus Nitocris, which is identical.
