 tures rugosopunctata 



Elytra with seven rounded equal costse, intervals with a series 

 of moderately shallow punctures oxygona. 



Elytra more attenuated in front, costee more acute, and punc-

Totally black, shining ; head very closely punctured ; prothorax 

 very cordiform, with the anterior angles projecting a little, and the 

 outer margins carinated, with the outer sides a little depressed, with 

 a broad median depression containing a very fine groove reaching 

 from the base to a transverse, arcuated, shallower impression in the 

 anterior part, each side of the disk owing to the lateral and median 

 depression is slightly raised ; elytra with the shoulders very sloping, 

 and the outer sides suddenly ampliated at about one-fourth of the 

 length, and subparallel nearly to the posterior angle, which is sharp, 

 and the outer margin truncated very obliquely from the outer angle 

 to the suture, the apical part of which broadly notched inwardly and 

 thus produced in a broad spine on each side ; they have each four 

 acute much-raised costse, including the sutural one, the outer one of 

 which is at a right angle with the humeral part, and thus hides from 

 view ; when looked at from above, the narrower part of the anterior 

 outer margin, the intervals are hairless with a double series of 

 broad, moderately deep punctures. Length 19 mm. ; width 22 mm. 



Hah. Cape Colony (Cape Town, Stellenbosch, Piquetberg).
