well-marked liind angle. The elytra are extremely finely 

 punctured and slightly shining, except at the apices. The 

 legs are very slender ; the lateral teeth of the front tibia are 

 not strong, the terminal fork is long and there is a long process 

 beneath at the point of insertion of the tarsus. The middle 

 and hind tibiae bear strong lateral spines and terminate in 

 three sharp spines. 



Variation of the male. In small specimens the front cephalic 

 ridge is only slightly indicated, the clyj^eal fork is represented 

 only by a lobe on each side of the epistome and the mandibles 

 are slender, gently curved and scarcely tootlied excej^t just 

 before the tip. Larger examjDles have the frontal ridge a little 

 elevated in the middle, a strongly diverging clypeal fork, a 

 small tooth near the middle of the mandible and a few minute 

 tubercles between this and the terminal fork. In full-sized 

 males the clyjieal fork is long but not strongly divergent, the 

 frontal ridge is very strongly elevated in the middle and the 

 mandibles are stout, with a strong tootli in the middle and 

 very strongly diverging tips.
