3. Helopbilus laetus Loew. 



One male from Sand Hills, Thomas Co., Nebraska. This species 

 also, as in H. integer, has the small black spots of minute spinous 

 bristles on the inner basal part of the anterior and posterior femora. 

 It is smaller than H. integer and the basal half of the front and middle 

 femora are black. Formerly recorded from Connecticut, New York, 

 Wisconsin, Michigan and New Jersey. 



4. Helopbilus latifrons Loew. 



Numerous specimens from Gering, Cedar Bluffs, West Point, 

 Hardy, Lincoln, Glen and Gordon, Nebraska. 



5. Helopbilus similis Macquart.

One female from Beatrice, Nebraska, July 8, 1904 (M. H. Swenk). 



I give a description of this specimen which is undoubtedly M. 

 bipartita. The only difference between it and the specimen of M. 

 cimbicifonnis is the lighter colored pile. I think that bipartita is 

 probably a synonym of cimhiciformis. 



2. Mallota cimbiciformis Fallen. 



One female from Milford, Nebraska, noted by Hunter in the Cana- 

 dian Entomologist, Vol. XXVIII, p. 99.
