 embrace the head ; sides diverging rapidly for two-thirds 

 of their length, then straight to the posterior angles ; disk 

 slightly raised in front, very deeply punctured; near the 

 posterior angle, on each side, and almost touching the 

 lateral margin, is a slight oblong depression, in which the 

 punctures are closer together. Elytra crenate, striate,

 below the shoulders, widest behind the middle, whence 

 they converge to the apex, which is rounded. Under-
