COLASPOSOMA. 



Genus COLASPOSOMA. 



Colasposoma, de Laporte, Silberm. Eev. Entom. i, 1833, p. 22. 

 Acis, Chevrol Cat. Dej. ed. 3, 1837, p. 435. 

 Thysbe, Dej. I. c. p. 435. 



Type, C. senegalense, Dej., from Africa. 



Range, Africa; India; Malayan Sub region ; 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, and 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.
