A species of very marked outline, owing partly to the 

 breadth of the elytra, and farther differentiated bj the 

 narrowing of the head. 



Zymaus, n. g. 



A Leptope differt imguicuUs connatis. 



The exponent of this genus bears a rather striking 

 resemblance to the Brazilian Bastactes bituberculatus, 

 Boh., and is, therefore, not unlike some of the more 

 normal forms of Leptops. It is probable that fresh indi- 

 viduals, judging from one of my specimens, are more 

 scaly than is here described, 



Zymaus binodosus. (PL VII. fig. 5.)
