joint, sides of face with very long, abundant black pile; palpi brown, 

 with mostly yeUow, bushy pile; proboscis short, labella fleshy; beard 

 yellow on lowest part and behind proboscis, black and stubbly above. 



Mesonotum opaque dark brown with a double median gray stripe, 

 rather indistinct, and gray pollen along the edges; scutellum dark 

 opaque brown; pile of dorsum long, mostly black except on the 

 middle of the anterior part; pleurae opaque brownish, with a])undant 

 pale pde; halteres deeply infuscated, the stems somewhat paler. 



Abdomen wholly black, rather velvety above, with long erect pale 

 pile. 



Front and middle tibiae with fuie short erect hairs on the apical 

 third, which continue on the first tarsal joint; front tibia widened at 

 apex on inner side into a ])lunt angle; aU the tibial spurs minute, 

 almost imperceptible. Wings subhyaline. 



Length, To- mm. 



A single male, Claremont, California (C. F. Baker, No. 8271). 



The species resembles johnsoni, but is darker in color, face about 

 twice as hairy, beard blacker, fourth posterior cell closed, etc. The 

 fourth cell is probably somewhat variable and possibly useless as a 

 character, as in one wing it is not quite closed, in the other entirely 

 so. From the small amount of material in hand of both species they 

 appear to be sufficiently distinct.
