This genus is allied to Cimatlan Dist., from wliich it 

 differs principally by the narrower and less flattened body, 

 the longer first antennal joint, the differently sculptured ver- 

 tex, and the presence of a distinct transverse impression to 

 the pronotum. Tt also bears a superficial resemblance to 

 Eustictus Reut. {Cimatlan V. Duz. nec Dist.), but this genus 

 belongs to an other subfamily and differs, apart from the 

 arolia, by many characters from Piasus and Cimatlan.

This insect is widely dispersed in the neotropical region. 

 I have seen specimens from Costa Rica (Turrialba and Tu- 

 currique) and Ecuador (Balzapamba).
