LONGICORN COLEOPTERA FROM BURMA 15 



Female. First and second abdominal segments elongated, the 

 first a little longer than the second, the latter as long as the 

 succeeding segments combined. 



37. Ibldionidum Corbetti, sp. n. {PL I, fig. 3). Sparsim cUiaius, 

 testaceus; prothorace quam latitudine basis duplo lonqiore, supra 

 utrinque leviler hinodoso, sparsim ciliato ; elytris testaceo-fulvis , 

 griseo suhtiliter puhescentibus, seriatim punctatis, puncfis setigeris. 

 Long. 7-10 mm. 



Hah. Burma. Two examples, a male and female, were captured 

 by M."" Fea at Yenang Young; the species has also been taken 

 at Paungdè by M"* G. Q. Corbett. 



The elongated thorax, somewhat raised and curved anteriorly, 

 gives this little species the aspect of one of the Ibidioninae. Its 

 characters show, however, that it belongs to the Obrionides. 



38. Thranius simplex, sp. n. Fusco-testaceus, corpore subtus pe- 

 dibusque teslaceis, his clavis femorum piceis, antennis fusco-ferru- 

 gineis articulis 8°. 9''-que testaceo-fulvis: capite prothoraceque griseo- 

 flavo pubescentibus , hoc antice lateraliter compresso, dorso gibboso 

 et in gibbo summo sub-asperato: elytris fiisco-ferrugineis, crebre 

 fo9'titerque punctatis, utrisque linea longitudinali paullo elevata et 

 ad basin extremam tuberculo parvo instructis , apicibus utrisque in 

 spinam productis. Long. 20 mm. 



Garin Mts. (district of Ghecù). One example. 



This species may be distinguished from T. gibbosus (with 

 which it agrees somewhat closely in structural characters) by 

 the rather dark brown colour of the entire elytra. 



So far as I can judge from the description of Singalia, and 

 of its type species, this genus, which Lacordaire placed in the 

 group of the Saper dides , appears to me to have been founded 

 upon the Thranius gibbosus of Pascoe. Lacordaire himself reco- 

 gnized that the genus presented characters which were quite 

 unusual in the group. But I feel strongly convinced that he 

 overlooked the fact that the characters were not only foreign 

 to the group, but even to the sub-family of the Lamiidae itself. 

 Lacordaire was not unacquainted with the genus Thranius, for 

 he has given a very full description of it in its proper place.
