front of wings and on 4th segment of abdomen golden 

 yellow pilose. Superficially resembles Pocota grandis.

 bare of pollen, subshining, front and face on the sides 

 heavily brown pollinose; cheeks shining black; pile on sides 

 of face golden, coarser, more elongate and mixed brown and 

 black from antennal prominence to eye margin; front, vertex

 segments deep shining mahogany, sub-equal in length, third 

 segment dull brownish black, lighter basally, the segment 

 thick, about one-half broader than long, not produced mater- 

 ially at any angle, arista deep brownish black. Proboscis 

 produced, heavy and blunt. 



Thorax and scutellum black, subshining. Pile elongate, 

 dense, yellow in front of wings on dorsum and pleura, black 

 behind wings and on scutellum. 



Abdomen black subshining, fourth segment with obscure 

 metallic reflections; pile elongate black; on apical two-thirds

 mixed brown and black. 



Legs black, knees briefly reddish brown; pile on femora

Holotype, female, No. 841, Mus. Calif. Acad. Sci.; A. B. 

 Black, collector, June, 1919. A second female, paratype, 

 was collected at the same time and place by A. L. Lovett 

 and is in his collection. 



Type locality, Mary's Peak, Oregon. 



This species is very near coquilletti Will, and may prove 

 to be a synonym. The extreme disparity in size and appar- 

 ent facial and antennal differences are all that seem specific. 

 No opportunity has been afforded to compare the two.
