THE CANADIAN ENTOMOLOGIST. 237 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. Family Tipulid.e. Rhipidia fidelis O. S. Limnobia triocellata O. S. Erioptera armata O. S. Erioptera caloptera Say. Liogma iiodicornis O. S. Biitacomorpha clavipes Fabr. Oropeza vetiosa Johnson.
