 from base, rounded at anterior angles, coarsely punctate, more densely 

 at sides, j)unctures ocellate; a broad median channel from base to 

 middle, where it abruptly ends ; base transversely and deeply impressed 

 at the sides; posterior angles not divergent, carinate. Elytra as broad 

 as thorax, parallel for two-thirds of the length, deeply punctato striate;
