A SYNOPSIS OF THE TABANIDAE OF NEBRASKA, 



WITH A DESCRIPTION OF A NEW SPECIES 



FROM COLORADO 



BY EVERETT E. WEHR 



UNIVERSITY OF NEBRASKA 



Recently, the writer has had occasion to prepare a synop- 

 sis of the species of Tabanidae, otherwise known as horseflies, 

 deerflies or gadflies, of the State of Nebraska. These flies are 

 of importance to the farmer and stock raiser because of their 

 blood-sucking propensities and their annoyance to stock. They 

 breed in marshy lands and wet soil. This synopsis is based 

 altogether on specimens collected in Nebraska and now ac- 

 tually present in the University of Nebraska collection. 

 It is not probable , therefore, that it is a complete list. More 

 extensive collecting over the state would probably reveal the 

 presence of other species, since very little time has been spent 

 in especially collecting these insects. 



The classification of Hine has been followed in the main, 

 but in listing the species those that are closely related have 

 been brought together. The writer is indebted to Professors 

 Myron H. Swenk and R. W. Dawson of the University of Ne- 

 braska, who have made possible the preparation of this paper. 

 Acknowledgement should also be made to the works of Pro- 

 fessor James S. Hine and Baron C. R. Osten Sacken on the 

 Tabanidae, since these have contributed greatly toward the 

 satisfactory identification of the species and the synoptic 

 work.
