Phricobacis. 



g. n. (typ. Batesii, Crotch). 



This genus differs from Bacis by its large size and oblong form, 

 close rugulose punctuation and different structure of the proster- 

 num. This is intermediate to some extent between Bacis and Pri- 

 otelus, the side pieces are on the same plane, but the prosternum 

 extends widely to right and left of the coxse.

Tlie black dots on the thorax vary, some being absent occa- 

 sionally; the Amazon specimens are of an olive brown, with pale 

 ochreous thorax, probably arising from discoloration or immaturity.
