Tlie blunt convex pronotum makes this an easily recog-

The species is distinguished by the strongly reflected 

 anterior margin of the pronotum, which is continuous with 

 the lateral bands, so that these are connected with each other, 

 when viewed from the ventral side. The lateral bands of the 

 pronotum are bent down anteriorly at more than a right 

 angle to the disk.

This, the only West-African representative of the genus, 

 can be distinguished by the rugose and tuberculate pronotum 

 with reflected and dentate posterior margin in the male and 

 the dentate lower margin of the lateral bands in the female. 



The following is a description of the female : — 



Piceous. Head castaneous, finely punctate. Antennae 

 testaceous at base, remainder castaneous. Pronotum coarsely 

 tuberculate and punctate, anterior margin reflected; lateral 

 bands finely tuberculate, rather broad, anteriorly bent down 

 at more than a right angle to the disk, not closely adpressed 

 to disk, the pronotal channel being wide and shallow, poste- 

 riorly produced, their lower border dentate ; from the ventral 

 aspect the lateral bands are seen to be in communication with 

 each other anteriorly, as in C.jallce, Gig.-Tos; disk carinate, 

 posterior margin dentate. Meso- and metanotum carinate, 

 punctate, and with a few tubercles. Abdomen very finely 

 punctate. 



Total length 16 mm.; pronotum 4'9x4 mm. ; pronotum, 

 (J , 4-4 X 4 mm.
