Dolichopus bifractus Lot'w. 



Iowa (Osborn); Ohio and New Hampshire (^Veed); 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 Locw, 



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

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

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

 of the tegulas are said to be yellowish, which is a misprint. In three 

 other places he calls them black. 



Dolichopus reflectus, n. sp. 



Female. Antennas red; cilia of tegula:^ black, of inferior orbit pale; 

 fourth vein of wing broken, hind tarsi and tips 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; pleurce blackish-green, with white dust. Abdomen 

 bronze-green, not very bright. Fore coxaj yellow, thickly clothed in 

 front with minute black hairs. Posterior coxas black, with yellow 

 tips. Fore tarsi scarcely longer than their tibiae, 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, Philadelphia, May 30 (C. W. Johnson). 



Dolichopus vittatus Loew. 



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 present species from 

 cuprinus, although representatives of both are probably before me. 



Dolichopus cuprinus Wiedemann. 



Nineteen specimens. The male differs from riffa/iisin 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 tl-te wider wings. The species is of wide 

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

 Ohio, Kansas and South Dakota.
