fence. Elytra much broader than the thorax, robust, with deep and 

 irregularly scattered punctures arranged throughout in the form of 

 stria?; near the scutcllary angles are two broad and prominent 

 tubercles, while behind them, occupying the whole of the surface 

 nearly as far as the apex of the elytra, are distributed five others, 

 irregularly disposed, and in form slightly longitudinal ; the humeral 

 angles at their extremity are distinctly gibbous, so that the breadth 

 across the shoulders is greater than the medial breadth; 1 1 1< - whole 

 surface is uneven and irregular, and clothed throughout (when viewed 

 under a high power) with a short and thick piceous pubescence. An- 

 tennae-, the two basal joints fulvous (the rest, in the example before 

 me, arc wanting). Legs piceous ; the posterior tibia? and the extreme 

 apex of the femora fulvous ; the anterior tibia? arc banded with fulvo- 

 fuscous.
