Type, C. senegcilense, Hej., from Africa. 
lianr/e. Africa; India; Malayan Subregion ; Australia. 
Short, oblong and convex, metallic, rarely pubescent above. 
Head deeply inserted in thorax, flat; antennae filiform, terminal 
joints more or less widened. Thorax transverse, sides more or 
less rounded, not narrowed in front. Elytra slightly punctate- 
striate, generally rugose at the sides in the female. Legs robust ; 
femora thickened, sometimes armed with a tooth beneath ; tibiae 
sulcate, dilated and curved at apex in the male, simple in the 
female. Prosternum . nearly quadrate, frequently pubescent ; 
anterior margin of thoracic episternum concave. 
The insects which constitute this genus are of very variable 
sculpture, closely allied and difficult to separate, aud the specific 
distinction of many is often a case of conjecture only. The 
examination of the male organs is a useful guide to the identifi- 
cation of the species. 
Species more or less pubescent above.
