large, ovate. Prothorax (6 x 6 -5 mm.) strongly rounded on sides, 

 apex with postocular sinuosity rather strongly marked; disc de- 

 pressed along median line, and with collar-constriction; finely, 

 almost minutely, granulate, the granules rounded, contiguous ; sides 

 granulate to coxae. Elytra (14 x 8 mm.) gently widened to 

 behind middle, apex moderately produced, rounded, base feebly 

 arcuate; each elytron with three, broad, double striae on disc, each 

 shallowly and closely cross-reticulate, with an indication of an 

 intermediate interstice in centre; interstices four in number, all 

 (including sutural) prominent, costiform, and extending from base 

 almost to apex; sides obsoletely strio-reticulate, interstices sub- 

 costate. Beneath, with a median vitta of dark brown hair; fifth 

 with a shallow depression at apex. Anterior femora with a sharp 

 spine near base.

 larger, not so dilatate ; elytra (14-5 x 8'5 mm.) more strongly 

 rounded, apex more produced, strongly mucronate and dehiscent, 

 structure on sides more obsolete; beneath, feebly convex, with a 

 feebler, more yellowish vitta; fifth segment with a longitudinal 

 depression at apex; femora not spined. Dimensions: <J. 21 x 8 ; 

 9. 22-5 x 8-5 mm.

 collis being the male, and T. hiscipennis the female. 



The species seems to combine characters belonging to the first 

 two groups of the section Costati, the rostrum being similar to that 

 of T. rugifer, while the elytral sculpture is not deeply foveate, but 

 is like the sculpture in T. Kirbyi.

Black, nitid, practically without clothing, save for a yellow

Head depressed in front; rostrum excavate, external ridges 

 slightly convergent, continued on to head; internal long, conver-
