Specimens examined: 164, from Omaha, Lincoln, Fair- 

 mont, West Point, Ravenna, and Mitchell, collected from 

 April 4 to July 5. Like fimetarius, this is an European 

 species which has become practically cosmopolitan. It is 

 often seen flying in large numbers at sunset on warm spring 

 evenings.

Specimens examined: 53, from Fairmont, Holt Co., Hal- 

 sey, Mitchell, and Warbonnet Canyon in Sioux Co., collected 

 from May 16 to August 4. Vittatus is evidently much com-

 majority of the specimens listed coming from Mitchell where 

 the writer found the species abundant in middle June.
