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. Antenne 
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, asin C. jalle, Gig.-Tos; disk carinate, 
posterior margin dentate. Meso- and metanotum carinate, 
punctate, and with a few tubercles. Abdomen very finely 
punctate.
