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 Fri- 

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

 extends widely to right and left of the coxoe.

The bhick dots on the thorax vary, some being absent occa- 

 sionally; the Amaz<m sj)eGimens are of an olive brown, with pale 

 ochreous thorax, probably arising from discoloration or immaturity.
