jointed, with stout, legs and prominent mandibles, the head 

 very large and forming (in the male) the widest part of the 

 body. The eyes are very small, prominent and hemi- 

 spherical, and placed at the sides of the head, which is dilated 

 behind them, so that their position is oblique. There is a 

 straight incised line at the back of the head, continued forward 

 on each side as far as the base of the antenna. The antennae 

 are more than half the length of the body, and consist of 

 eleven loosely-articulated joints, all a little elongate, but

between the eye and the base of the mandible. The man- 

 dibles are large and prominent, rounded externally and 

 bluntly bifid at the tip, with two or three blunt internal teeth. 

 The clypeus is broad and slightly emarginate in front, the 

 labrum semicircular and closely fringed at the edge. The 

 terminal joints of all the palpi are fusiform and elongate. 

 The pronotum is nearly three times as wide as it is long and 

 slightly wider than the widest part of the elytra. The front 

 and hind margins are nearly straight, the sides strongly and 

 regularly curved, completely obliterating the hind angles. 

 The front angles are rather minutely excised. There is a
