124 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.49. 



Abdomen entirely brownish-cinereous poUinose, the ground-color 

 changing to yellow in the latter part of the fifth segment. 



Front and hind coxae with yellow pile; middle coxae slightly yel- 

 low at tip. 



Wings slightly and uniformly yellowish-brown. 



Length, 5.6 mm. 



In liis 1894 paper CoquiUett placed this species as a synonym of 

 latipalpis Bigot ( = plagens Williston) ; but he evidently receded from 

 this opinion later, as in the United States National Museum collection 

 I found a row of 8 females bearing the nsiine fulvipes in Coquillett's 

 handwi'iting. They are very close to the type in their characters, 

 but on account of their having much shorter pile on the front, lighter 

 pollen on mesonotum, and other slight discrepancies, I did not feel 

 sure of the identity, but consider them to belong to Tiirta. 



From its early dnie fulvipes is without question a valid species; it 

 is closely allied with hirta and cinerea, one or both of which may ulti- 

 mately prove to be synonyms of it. No western males of the group 

 are yet in collections, as far as I have seen; in a considerable number 

 of females (about 36) from the West, there seems to be much varia- 

 tion in the amount of yellow in the antennae, and in the femora, etc. ; 

 none of them agree entirely with the type of fulvipes, and I believe 

 they mostly go in Jiirta quite readily; however, the distinctions 

 between Mrta and cinerea almost or quite vanish in a large series, and 

 I doubt if both can ])e maintained unless it shall be proved that the 

 halteres of the male cinerea are infuscated, of which there is some 

 prospect, as I have indicated under that species.

Symjjhoroviyia hirta Johnson, Ent. News, vol. 7, 1897, p. 120. Philadelphia, 

 Pennsylvania (one male, two females). — Adams, Kans. U. Sci. Bull., vol. 

 2, 1904, p. 439 (flavipalpis). Wasatch Mountains, Utah; Colorado (a female 

 from each locality). 



Male (type redescribed). — A robust black cinereous species with 

 bare face, convex third antennal joint, yellow halteres, black femora 

 and yellow tibiae. 



Eyes barely contiguous, vertical triangle with very long, abundant 

 black pile; frontal triangle bare, cinereous; first joint of antenna 

 black, cinereous, very little swollen, with long black pile above and 

 below; second and third joints missing (according to Johnson they 

 were dark brown); face bare; palpi blackish, with bushy whitish 

 pile like the beard ; proboscis short, fleshy. 



Mesonotum black, cinereous, somewhat glaucous, with three iU- 

 defined wide blackish stripes, narrowed behind; pile bushy and black; 

 scutellum glaucous, with very long erect black pile; pleurae blackish, 

 with thin pollen and rather abundant delicate pale pile; halteres 

 wholly yellow.
