" . Dark brown, not shining, except the abdomen, the man- 

 dibles, the anterior margin of the head, the antennae, the anterior 

 portion of the pedicel, the apex of the abdomen, the femora 

 and the joints of the tibiae and tarsi, which are reddish yellow. 

 Head, thorax and nodes, also the scape of the antennae, granulate; 

 abdomen smooth and shining, with some longitudinal striae at base. 

 The head with somewhat short, thick, recumbent yellow hairs ; 

 pilosity sparse : the hairs on the anterior margin of the scape and 

 on a portion of the sides of the head bent or curved towards their 

 apices. Legs pilose, the pilosity thickened on the tarsi and also 

 on the ftagellurn of the antennae, where, however, the hair appears 

 to be more recumbent. 



" The mandibles are porrect, about as long as the head, from 

 the point where they are thinnest to the margin of the mouth 

 nearly in the form of a lyre, at the base they are slender, then 

 rounded and broad, and again diminishing ; on the outer side 

 thick and convex, on the inner margin concave and sharp ; the 

 apex is bent at a right angle inwards, and ends in a sharp upper 

 tooth and a split under one." (Roger.)
