3. Mallota fascialis Hunter. 



Type specimen and five metatypes from Lincoln and Sioux Co., 

 Nebraska. In the eastern specimens the epistoma is slightly less pro- 

 jecting than it is in the western ones, and there is also some variation 

 in the size of the insects. The females agree with Hunter's descrip- 

 tion of the male. This is evidently quite a variable species. 



4. Mallota illinoisensis Robertson. 



One female from West Point, Nebraska, June 22, 1906. The hind 

 femora have scarcely any black on them, and the third joint of the 

 antenna is broader than long. Length 12 mm. Otherwise it answers 

 to Robertson's description. Formerly recorded from 111. 



5. Mallota posticata Fabricius. 



One female from Nebraska City, Nebraska, September 14, 1901 

 (M. A. Carriker). 



Formerly recorded from Carolina, Pennsylvania, New York, New 

 Jersey, New Hampshire, Canada and Kansas. 



26. TRIODONTA Williston. 

 I. Triodonta curvipes Wiedemann. 



One male from Lincoln, Nebraska. Formerly recorded from 

 Nova Scotia, California, Colorado and New Jersey. 



27. SYRITTA St. Fargeau et Serville. 

 I. Syritta pipiens Linne. 



Numerous specimens from Beatrice, Cams, Lincoln and Glen, 

 Nebraska. 



28. XYLOTA Meigen. 



1. Xylota analis Williston. 



One male from War Bonnet Canon, Sioux Co., Nebraska, noted 

 by Hunter in the Canadian Entomologist, Vol. XXVIII, p. 100. 



2. Xylota angustiventris Loew.

 Canadian Entomologist, Vol. XXVIII, p. 10 1, and a male from West 

 Point, Nebraska.
