Sent in numbers from Costa Rica. It lives in a species of Cereus, according to 





■ 



Biolley, and there is an example from Colombia in the Fry collection labelled as 

 having been found on the same genus of Cactacese. This insect is extremely like 



■ 



the immaculate form of C. spinolce, but may be easily distinguished therefrom by the 





deep, oblong, foveiform impressions of the elytral striae. It bears much the same 

 relation to the Mexican C. fahrcei as the northern C. validus does to C. spinolce, and 

 replaces the former as we go southward.
