This paper although incomplete in many respects is offered 
as an aid for determining the Taltanidas 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 Vjeen aided in various ways and without 
this help I realize that it would not have been possible to do 
much that has been done. It is with the greatest pleasure there- 
fore, that I make the following acknowdedgements: 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 numerous 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
