VITTATE CHRYSOMELID BEETLES DISONYCHA — BLAKE 31 



Zone. Whether D. peruana and D. militaris are of varietal or specific 

 status seems at present impossible to determine. 



In regard to the label Chiriqul, Costa Kica, I have found a number 

 of specimens so labeled that belong elsewhere, for example Disonycha 

 spilotrachela Blake, known only from the West Indies, and Disonycha 

 hicarinata Boheman, from Argentina. Therefore I believe this speci- 

 men may also be ^vrongl3'^ labeled.

 the eye, frontal tubercles faintly marked, carina narrow, a little 

 produced, lower front moderately long. Antennae dark except for the
