528 REVISION OF THE GENERA COLPOCHILA, ETC. 



A fine robust species, nearest I think to C. pii/iictiventris but 

 with the clypeus much shorter (at the base quite twice as wide as 

 it is long down the middle), the sides of the pro thorax very much 

 more strongly rounded, elytra spinose at the sutural apex, 

 pygidium differently sculptured, &c., &c. I am not certain of 

 the sex of the two examples before me ; the comparatively short 

 and stout hind tarsi point to their being females. 



S. Australia. 



COLPOCHILA BICOLOR, Sp.nOV. 



Elongato-ovata ; minus nitida ; niger, antennis palpis pedibus 

 nonnihil picescentibus, ely tris brunneo-testaceis anguste nigro- 

 cingulatis ; pectore cinereo-hirsuto, abdomine sparsim setoso ; 

 capite (hoc minus brevi) confertim rugulose, prothorace con- 

 fertim subrugulose, elytris (his geminato-striatis) sat sparsim 

 minus fortiter, pygidio (hoc antice subconcentrice rugato) et 

 subtiliter et minus subtiliter, punctulatis; antennis 9-articu- 

 latis ; prothoracis basi bisinuata, quam margo anticus hiijiis 

 dimidio latiori, angulis posticis (superne visis) subrectis ; 

 elytris apice suturali breviter spinoso-productis. 



Maris (?) antennarum flabello stipitis dimidio paullo longiori, 

 3-articulato, stipitis articulis ultimis 2 intus breviter obtuse 

 dentatis. [Long. 8 (vix), lat. 44 lines. 



The prothorax is just twice as wide as long ; from the front 

 angles (which are acute and rather strongly prominent) the sides 

 (as viewed from above) diverge almost witliout sinuation to well 

 behind the middle, where they are strongly rounded ; tbey then 

 converge, with very slight sinuation to the base. 



The almost rugulose puncturation of tlie prothorax and [lale 

 brownish yellow elytra each margined all round very narrowly 

 with black, or dark piceous, renders tliis a very distinct species. 

 I think the examples I have seen are all of one sex, and I believe 

 them to be males on account of the hind tarsi being comparatively 

 slender and elongate. 



S, Australia (?) ; probably from the interior.
