truncated process, the width of which is equal to the distance be- 
tween the eyes at the clypeus; middle carina strong; mandibles 
bifid at apex, with three inner teeth, the first tooth small; first joint

Habitat—Fiorissant, Colo., June 26, 1907 (S. A. Rohwer). 
In Fox’s table (Crabronine of N. Amer.) this species runs 
near montanus Cress., but it may be known from all of that 
group by the different sculpture, larger size, fringe at side of 
pygidium, etc. Disregarding the structure of the clypeus it runs 
to trifasciatus, but is at once known from this by the ocelli being 
in a lower triangle.
