14 KANSAS UNIVERSITY QUARTERLY. 



Wings hyaline, fourth vein rather abruptly bent, costa with a small, 

 short thickening at the apex of first vein. 



Female. Face a little lighter yellow, and wider; fore tarsi blackened 

 from the tip of the first joint; hind tibiae simple, costa not thickened. 



Length, 5.2 mm.; of wing, 4.1 mm. 



A male and a female, Douglas county, Kansas, June 24 and 29, 

 (U. K.). 



Dolichopus comatus Loew. 



Five males and three females. New Jersey and Pennsylvania, May 

 30 to July 24 (C. W. Johnson). The first joint of the fore tarsi is, in 

 both sexes, of nearly the same length as the remaining four. This is 

 quite characteristic. 



Dolichopus brunneus n. sp. 



Female. Small, shining dark bronze species; antennae black, cilia 

 of inferior orbit pale, of tegulae black, legs yellow. 



Face broad, more so above, yellowish gray; front greenish bronze. 

 Thorax dark bronze, moderately bright; pleurae gray pollinose; hal- 

 teres and tegulae yellow. Abdomen slightly more bright than thorax. 

 Legs yellow; posterior coxae black, fore coxae yellow, with a trace of 

 infuscation at the base, on the fore side with minute black hairs. Fore 

 and middle tarsi blackened from the tip of the first joint, about as 

 long as their tarsi. Hind tarsi and tip of tibiae black. Wings 

 narrow, slightly tinged with brown, the anal angle not prominent; 

 costa with a slight, long enlargement. 



Length, 3 mm.; of wing, 2.8 mm. 



One female, Brookings, S. D., June 18. The smallest North 

 American species. 



Dolichopus incisuralis Loew. 



In the neighborhood of this species I have a number of females 

 from Connecticut, (U. K.), New Jersey and Pennsylvania (Johnson), 

 Ohio (Weed), and California (Coquillett). Some of them may belong 

 to setosus. Not having any males, the separation of the two species 

 is practically impossible. 



Dolichopus obcordatus, n. sp. 



Antennae black, cilia of inferior orbit pale, of tegulae black; legs 

 yellow, coxae and tip of hind tibiae black; fore tarsi of male with the 

 last joint flattened, obcordate, deeply notched at the end. 



Male. Face yellow pollinose, front shining yellow-bronze, green 

 along the edges. Antennae moderately large, especially the third 

 joint. Dorsum of thorax green, rather coppery; pleurae dark green.
