eye. The pronotuin smooth, its lateral margin gently rounded 

 to the acute lateral angle and concave to the very obtuse 

 hind angle, the base gently rounded. Tlie scutc^hnn smooth 

 or punctured. The elytra very hnely and closely jjunctured, 

 excei)t close to the suture, where the punctures are very 

 sparse and minute, the shoulders rounded. The prosternum 

 rounded behind, not compressed nor pointed. The three 

 lamellae of the antennal club short and the seventh joint 

 little produced. The front tibia is forked at the end in both 

 sexes and the middle and hind til)i8e have each a strong lateral 

 spine. 



$. The head is roughl}^ and irregularly punctured and bears 

 a pair of tubercles placed close together in the middle. The 

 clypeal process is feebly bilobed and not broad. The pronotum 

 has a few scattered punctures at the sides. The last ventral 

 sternite. is finely and closely punctured. 



^. The head is flat, smooth and very opaque, the mandibles 

 short, very strongly rounded and for apart at the base. The 

 clypeal process is short and broad, with the front edge straight 

 and fringed with yellow setae. The mandibles are flat at the 

 base, where they are a little dilated externally, and bear a 

 sharp internal tooth, directed slightty backwards. The 

 pronotum is minutely coriaceous, without visible puncturation, 

 and the front angles are obliquely truncate. The lower 

 surface is very smooth. 



Variation of the male. There is very little variation. In 

 small examples, where the mandibles are scarcely as long as 

 the head, the tooth is not far removed from the base. In 

 large ones the mandibles are a little longer than the head and 

 the tooth approaches the middle of their length.
