Eristalis aeneus (Fabricius) . Ent. Syst., iv, 302 (1772-94) ; Williston, 

 Synop. N. A. Syrph., 161 (1886). 



Thirty-two s $ and twenty-six $ 9 collected in the 

 eastern part of the state at the following places: Lincoln, 

 Lancaster County; West Point, Cuming County, and Omaha, 

 Douglas County, between April 10th and November 1st.

Three $ 6 and five ? ? taken at Brock, Nemaha County; 

 South Bend, Cass County, and Lincoln, Lancaster County, in

Eristalis furcatus Wiedemann. Auss. Zweifl. Ins., ii, 176 (1828); Will- 

 iston, Trans. Amer. Ent. Soc, xv, 279 (1888). 



A $ is at hand labeled "Lincoln, Lancaster County, June." 

 Heretofore at least, to the knowledge of the writer, this 

 species has never been collected farther north than Browns- 

 ville, Texas, and in no great numbers north of Central 

 America. I am unable to acount for its occurence in this 

 state. With only one specimen in the collection there is a 

 chance of it having been wrongly labeled.
