We have received a large number of specimens of this species ; it is a common 

 insect on the Atlantic slope of Guatemala and also at Chontales. C. juani, Cand., a 

 specimen of which determined by the author is before me, is based upon abraded 

 examples of C. bonplandi, with the marginal stripe of the thorax and elytra slightly 

 paler than usual. The two forms were collected together by myself at San Juan in 

 Vera Paz. I have seen five males, three in the Janson collection and two in our own. 

 In one specimen from Chontales the scales on the dorsum are violaceous. This species 

 differs from C. rugatus in having minute metallic scales on the dorsum of the thorax 

 and on the elytral interstices (in C. rugatus and its variety pistorius the scales on these 

 parts are elongate and white) ; the marginal stripe on the thorax is also broader, and is 

 widened posteriorly. Worn specimens are scarcely distinguishable from C. rugatus.
