f ABANIDAE of OHIOs 



WITH A CATALOGUE AND BIBLIOGRAPHY OF THE SPECIES 

 FROM AMERICA. NORTH OF MEXICO. 



INTRODUCTION. 



With Osten Sacken's admirable "Prodrome of a Monograph 

 of the Tabanidse of the United States," most of the species of the 

 family from the eastern part of our country may be identified 

 readily. And with Williston's paper in the tenth volume of the 

 Kansas Academy of Sciences most of our species not included 

 in the above contribution are fully characterized. Hart's paper 

 in the fourth volume of the Bulletin of the Illinois State Labor- 

 atory of Natural History is also useful in separating the various 

 stages of the genera Tabanus and Chrysops, and is an important 

 contribution to the life histories of a number of species of these 

 two genera. The economic position occupied by the family is 

 admirably treated in Osborn's paper on "Insects Affecting Do- 

 mestic Animals," in Bulletin number five, new series, of the 

 United States Division of Entomology. Other important con- 

 tributions have appeared from time to time, but a thorough ac- 

 quaintance with all this literature will not always give the stu- 

 dent of the group the information he desires regarding points 

 which come up in connection with many of the species of our 

 fauna. 



It is my intention in this paper to give some of the results 

 of observations on habits taken during a somewhat extended 

 study of members of the family, and follow with a systematic 

 treatise of the forms known to occur within the bounds of the 

 state of Ohio. At some future time, when the necessary mate- 

 rial has accumulated it is the intention tO' give a full treatise of 

 all the forms known to occur in North America.

 mitting material for study :

 parative Zoologv ; F. L. Harvey ; Charles Dury ; H. A. Gossard ;
