 cimens a dark brown transverse mark on the abdomen ; head and 

 thorax lightly and finely longitudinally striate, the nodes of the 

 pedicel delicately rugulose ; abdomen smooth, highly polished and 

 shining ; pilosity pale, very sparse and short, pubescence almost 

 entirely absent." Head without the mandibles trapezoidal, very 

 much broader posteriorly than in front; mandibles triangular, 

 very broad at the masticatory margin, very minutely longitudinally 

 striate ; clypeus convex, its anterior margin arched, posterior 

 margin wefl defined, broadly rounded in the middle between the 

 base of the antennae ; antennal carina wide apart, produced as 

 fine striae nearly to the top of the head, bordering a space very 

 finely rugulose but not striate nor forming a groove for the 

 reception of the scape of the antennae ; antennas rather thick and 

 comparatively long, the scape extending quite up to the top of the 

 head ; eyes round, placed a little above the middle of the sides of 

 the head. Thorax comparatively short, broad and convex ante-

 spines ; the femora and tibiae of the legs only slightly incrassate 

 in the middle. Pedicel short, the nodes large ; the 1st node
