This species may easily be distinguished from all others

$. Length 11 mm. Black, clothed with black pubes-

Mandibles black with a slight reddish tinge in the center, 
with three teeth, the inner one of which is very short, the 
second one extending two-thirds of the distance from the 
first to the tip of the third. Both of the first two teeth are 
weak, the third tooth is strong. Pubescence on the man- 
dibles long, light colored toward the tips. Scape of an- 
tennae pubescent, bearing a number of long black hairs, 
the pedicel about one-fourth as long as the first segment 
of the flagellum, the flagellar segments subequal in length, 
the apical segments becoming slightly longer. Clypeus flat. 
A frontal ridge extending forward between the antennae 
and connecting with the clypeus. Head densely punctate 
with large, shallow punctures. Punctures on prothorax, 
scutellum and metanotum similar to those on the head. 
There are two subparallel lines on the mesonotum and a 
deep groove at the base of the scutellum. Dorsal surface 
of the propodeum with a longitudinal groove crossed by a 
transverse ridge at about two-fifths of the distance from 
the base, and separating the dorsal from the posterior sur-
