198 Mr. J. O. Westwood's Descriptions 



three raised tubercles, one near the inner base of each mandible, 

 and the other in the middle of the hind part of the crown of the 

 head. The mandibles are about the length of the head, very 

 robust, cvu'ved, each with a raised tubercle in the middle, on the 

 upper side, and the apex broadly and transversely truncate, with 

 two or three obtuse short teeth: the base of each is internally pro- 

 longed on the under side, next the mentum. The prothorax is 

 broader than the elytra, the sides rounded, its widest part being 

 behind the middle, and its hinder lateral angles prominent and 

 acute ; its upper surface is thickly covered with minute punctures. 

 The elytra are nearly round, with the fore part truncated and 

 straight ; they are smooth and convex, and but slightly polished. 

 The fore legs are robust, but of the ordinary form ; the tibiae 

 with three teeth on the outside, the first and second small, the 

 third subapical and large, as is also the apical point.
