cell also similar, being more acute than that of western female. 

 Length 8 mm. In general appearance, the western specimens 

 are larger and more thickly set. Formerly recorded from a fe- 

 male from Pennsylvania. 



4. Pipiza pistica Williston. 



A female from Pike's Peak, Col., July 20, 1906 (Prof. 

 Bruner), which agrees in every way with Williston's descrip- 

 tion, except all four joints of the anterior and middle tarsi 

 are blackish, the first one not so much so as the rest, the meta- 

 tarsi are yellow. The specimen is shorter and more robust than 

 I would infer from the description. 



5. Pipiza calcarata Loew. 



c?. — Bronze-black, white pilose, eyes greenish, pile white, in some 

 reflections black, front black pilose, whitish in some lights, face white 

 pilose appearing darker when viewed from below. Antennae black, 

 third joint reddish, broadly oblong, pile of thorax light colored. Pile 

 of the abdomen very short, longer on the lateral border, white. Legs 

 black, front tibiae except a broad blackish ring, middle tibiae less so, 

 first joint of four anterior tarsi luteous, last three joints blackish. 

 Hind coxae with a long slender process, compressed toward the end. 

 Wings except the extreme base cinereous, small cross vein from the 

 base of the discal cell and last section of the fourth vein from the 

 margin of the wing less remote than in P. femoralis, vein at outer 

 end of discal cell straight, not bent as in P. femoralis, which is only 

 slightly so. 



Formerly recorded from New York and New Jersey. 



6. Pipiza pulchella Williston. 



One female from Lawrence, Kansas, and a male from 

 Brookings, South Dakota, which agree with Williston's de- 

 scription, except the last three joints of the four anterior tarsi 

 are black, the last of the hind tarsi, black; second, brownish. 

 The face of the male is longer and more whitish pilose than the 

 female. Formerly recorded from females from Connecticut, 

 Massachusets, Florida, and New Jersey. 



7 Chilosia aldrichi Hunter. 



Two females from Pike's Peak, Col., July 22, 1906 (Prof. 

 Bruner), which agree with Hunter's description. The third 

 antennal joint is nearly black. Formerly recorded from Idaho.
