The upper surface is closely granular and opaque and has a 

 short oblique ridge on eacli side close to the eye and not 

 continued Ix'hind. The clypeal process is short and broad, 

 witli sliarp angles and acutely produced in the middle. The 

 mandibles are short, not regularly rounded but bent near the 

 middle, the terminal [)art very Hat, straight and sharj). The 

 pronotum is finely granular and opaque, the lateral margins 

 strongly but not sharply angulate in the middle and gentl}' 

 concave to the front and hind angles, which arj> very acute. 

 The ('lijtra are extremely glossy. The legs are very slender, 

 the front tibia very miiuitely serrate between the small latei-il 

 teeth. 



Vdridtion of the nude. In a small specimen the man lii)l('s 

 are rather stout antl have only a slight indication of a tooth 

 near the middle of the lower edge. In a larger male they are 

 more slender and have a laminar ililatition of the inner edge 

 produced a little downward and forward. 



3*. Length (with mandibles), 28-*U mm. ; (without mandibles)

2- Length, 29-32 mm. ; breadth, 13-14 mm.
