Abdomen narrow, opaque, darker above, with pale hairs, which 

 become woolly on the sides; principal hooks of the hypopygium are 

 yeUow to piceous. 



Coxae and femora black; middle coxa with several stiff, blunt 

 bristles at tip, curved backward and united to form a thornlike 

 structure. 



Wings shghtly infuscated toward the tip. 



Length 6 J mm. 



Female (not of CoquiUett). — Black in ground color, but with pale 

 cinereous pollen, the palpi, halteres, and front and middle tibiae 

 yellow. Front with short black hair; first joint of antenna very 

 short, with short black hair; third large, concave in profile below 

 arista, its vertical diameter fully equal to the length of entire antenna 

 from base to origin of arista; sides of face only slightly hairy; palpi 

 bright yellow, broad near tip, with short pale hair; proboscis fleshy, 

 shorter than height of head. 



Thorax and abdomen rather unifoim gray poUinose, with short pale

 scutellum ; halteres wholly yellow.

One pair, male and female, Pasadena, California, collected by F. 

 GrinneU, jr.; one male, Ormsby Co., Nevada (Baker). I also com- 

 pared the single male type in the United States National Museum. 



Coquillett named the species after Prof. O. B. Johnson, who was 

 for a long time a teacher in the University of Washington and an 

 enthusiastic collector of the animal life in and about Puget Sound, 

 but who has now for some twenty years been on the retired list on 

 account of ill health; although necessarily living a secluded life, Prof. 

 Johnson still retams a keen interest in his msect collections, and is 

 visited for inspiration and instruction by the younger biologists of 

 the Northwest, I note these facts as a tribute of respect and affection.
