Hab. Ega, on the Amazon. In Coll. Smith. 



This species closely resembles the C. quadrimaculatus, but it is 

 considerably smaller ; on a comparison with examples of that 

 species the following differences present themselves : the head is 

 of a different colour and much more oblong, the sides being much 

 more straight ; the thorax is more elongate, and the metathorax 

 has at its base, on each side, a small angular tooth ; its thorax 

 and abdomen are sub-opake, in C 'i-7naculatus they are shining.
