[Mar. 
Body rather coarsely punctate, much as in the section 
with the dark stigma ; hair on face short and silvery, but 
long on edges of lateral lobes, that on vertex dark, on 
pleura and propodeum longer and pale, abdomen scarcely 
hairy above, below with a band of rather short hairs on 
each segment. 
Face moderately broad below, no clypeal process, and 
the broad middle lobe scarcely reaches below the lateral 
lobes ; enclosure with a median groove and the sides 
roughened, but hardly striate; basal joint of abdomen 
about as long as broad, not half the apical width of second 
segment ; pygidium elongate, narrowed at each end, more 
so at base, fully two and a half times as long as broad in 
middle; the front tarsi (except basal joint) are more 
broad than usual ; teeth on upper edge of hind tibiae very 
strong.
