THE TABANIDiE OF WESTERN UNITED STATES AND 



CANADA.* 



James S. Hine. 



This paper although incomplete in many respects is offered 

 as an aid for determining the Tabanidae of the part of the coun- 

 try not so thoroughly covered by Osten Sacken's most valuable 

 Prodrome. I have spent much time and study on an extensive- 

 collection of Tabanids from the region, and although I have not 

 satisfied myself in all particulars, some definite conclusions have 

 been reached which are offered with the desire that they may 

 be of service to future students. 



In this work I have been aided in various ways and without 

 this help I realize that it would not have been possiV)le to do 

 much that has been done. It is with the greatest pleasure there- 

 fore, that I make the following acknowledgements: The U. S. 

 National Museum has loaned me all their undetermined material 

 and Mr. Coquillett has aided me materially besides; Dr. Snow of 

 Kansas University has loaned me much undetermined material,, 

 as well as the material he and his associates have collected on 

 several of his ntnnerous collecting trips in the West; Prof.R. C. 

 Osburn has donated several hundred specimens he collected in 

 British Columbia during two summers spent at the Minnesota 

 Seaside Station; Prof. R. V. Harvey of the Queen's School, Van- 

 couver has sent me a large quantity of excellent material from 

 his region; the University of Illinois through Dr. Forbes and 

 Prof. Hart have sent me material for study and Prof. Chas. W. 

 Johnson of the Boston Society of Natural History, besides send- 

 ing me much material for study has aided me in other ways. Dr. 

 James Fletcher and Profs. E. D. Ball, V. L. Kellogg, R. A. Cooley 

 and M. J. Elrod have each furnished valuable material. From 

 this variety of sources and from other collectors I shall mention.
