Dolichopus bifractus Loew. 



Iowa (Osborn); Ohio and New Hampshire (Weed); Lawrence, 

 Kansas; Brookings and Custer, S. D.; Fargo, N. D. Sixty speci- 

 mens. This is perhaps the commonest Dolichopus throughout the 

 northern states. The opaque thorax, red antennae, and broken fourth 

 vein render a wrong identification very unlikely, even to a beginner. 



Dolichopus ramifer J^orw. 



Nineteen specimens, both sexes; Douglas Co., Kans. (U. K. ), 

 Brookings, S. D., Mich., Ames, la. (Osborn). Montana (Co(iuillett). 

 Very easy to recognize in either sex. In Loew's diagnosis tlie cilia 

 of the legulai are said to be yellosvish, which is a misprint. In three 

 other places he calls them black. 



Dolichopus raflectus, n sp. 



Female. Antennx* red; cilia of teguhv black, of inferior orbit pale; 

 fourth vein of wing broken, hind tarsi and tijis of hind tibiie black. 

 Face white, above a little yellowish; front blue. Thorax green, 

 considerably dusted with gray; a narrow central stripe and a wider lat- 

 eral one bronze; ])leura' blackish-green, with wliite dust, .\bdomen 

 bronze-green, not very bright. l''ore coxa; yellow, thickly clothed in 

 front with minute black hairs. Posterior coxi\e black, with yellow 

 tips. Fore tarsi scarcely longer than their tibia.*, infuscated from the 

 tip of the first joint. Hind tarsi wholly black; hind tibiae bristly, 

 black at tip. Wings with a brownish tinge; fourth vein broken, the 

 upper angle appendiculate in one wing, and very slightly rounded in 

 the other; the portion between the two angles runs in a slightly oblique 

 direction, so as to make acute angles with the other portions. 



Length, 5.2 mm.; of wing, 4.7 mm. 



One female specimen, Philadeljjhia, .May 30 ( C. \\'. Johnson). 



Dolichopus vittatus Lotw 



One male, Brooking, S. D. The relation among the males of this 

 and the two following species is exceedingly close: as for the females, 

 I do not see any characters to separate the ])resent species from 

 cuprinus, although representatives of both are probably before me. 



Dolichopus cuprinus Wi«lemann. 



Nineteen specimens. The male differs from 7'itlatiis\x\ having the 

 fore tarsi ornamented with black hair, and the hind femora ciliated; 

 from longipennis in the length of the fore tarsi, the presence of cilia 

 on the hind femora, and the wider wings. The species is of wide 

 distribution, the specimens examined being from Mass., Pa., N. J., 

 Ohio, Kansas and South Dakota.
