A LIST OF DIPTERA TAKEN AT KEARNEY, ONTARIO, IN 



JULY, 1909. 



BY .MILLARD C. VAN DUZEE, BUFFALO, N. Y. 



The Diptera listed below were taken by me during a collecting trip 



to Kearney, July 2nd to 9th, 1909. As I had no thought at the time of 



publishing a list of the species taken, many of the common forms were not 



noted, but such unrecorded species are probably well known and widely 

 distributed. 



Kearney is located in the Parry Sound District, about fifty miles north 

 of Muskoka, and as many miles east of Parry Sound. It is surrounded 

 by low hills, from which most of the pine had been cut, the trees still 

 standing being largely birch. In many places there was a thick growth of 

 hazel and raspberry, and many Cornus bushes, which were in bloom at the 

 time, were scattered over the low ground. There are well-tilled farms 

 among the hills and along a valley through which a considerable stream 

 flows, and near the town widens into almost a lake and receives several 

 swampy creeks. There is, therefore, a great variety of conditions within 

 a small area about Kearney, and I found it an excellent location for 

 collecting insects. 



I am greatly indebted to Prof. C. W. Johnson for the determination 

 of a large number of the species enumerated in this list, and to Prof. J. 

 M. Aldrich for his determination of Dolichopidce and for his help and 

 encouragement which has enabled me to determine some of these species 

 myself I also wish to acknowledge my indebtedness to Prof. James 

 Hind, who kindly went over all the TabaJiidce, and to Dr. Johannsen and 

 Dr. Williston for the study of material. Where not otherwise indicated, 

 the species have been determined by myself 



The nomenclature here used follows the Aldrich Catalogue, except in 

 a {t\^ cases, where the change is noted.
