Specimens examined: 112, from Nebraska City, Lincoln, 

 Hooper, and Hat Creek valley in Sioux Co., collected from 

 April 26 to July 17. All but three of the above noted speci- 

 mens were taken at Lincoln where they occur commonly at 

 lights during the season indicated. The writer has also taken 

 them in some numbers late in the afternoon on freshly culti- 

 vated ground, but has never seen specimens about the drop- 

 pings of animals. ,

 coln, taken from May 19 to June 17. This species probably 

 occurs not infrequently in western Nebraska, but its occur- 

 rence in any numbers in the eastern part of the state is not 

 to be expected.
