$ . Brownish yellow, antennae and legs yellow ; in some spe- 

 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 well defined, broadly rounded in the middle between the 

 base of the antennae ; antennal carinae 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 antennas ; antenna? 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- 

 riorly, constricted at the mesonotum ; pro-mesonotal suture 

 obsolete ; meso-metanotal suture distinct, the anterior margin 

 of the metanotum a little raised behind the suture, basal portion 

 of metanotum transverse and very short, posterior to it a broad 

 groove divides the two short, stout, acute, divergent metauotal 

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

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

 rounded above, broader than long, anteriorly with a short petiole 

 bearing an appendix beneath ; 2nd node transverse, broader than 

 the 1st node, more than twice as broad as long ; abdomen oval.
