INSECTS AND THEIR ALLIES

 

systematically collected by anyone to my knowledge. Most of the names here listed were kindly contributed by Mr. M. C. Van Duzee, of Buffalo, who has, however, collected at Toronto on very few occasions. The Cecidomyidae were listed by Dr. Cosens. Most of the Svrphidae were collected by Dr. Brodie, and some additional species by the writer. A number of species in other families were also listed from Dr. Brodie's collection, while the Dolichopodidae, in addition to the species taken by Mr. Van Duzee, were collected and determined by the writer. In the Hemiptera, very little collecting has been done, and the few species listed, with the exception of the Aphididae and Coccidae, are in the collection of the Provincial Museum. The Aphididae are nearly all gall-forming species, the list having been kindly furnished by Dr. Cosens. The Coccidae, with one or two exceptions added by the writer, were taken from Mr. T. D. Jarvis's list of the Coccidae of Canada (41st Ann. Rep. Ent. Soc. Ont., 1910, p. 64-77). The Orthoptera and Odonata were collected and determined by the writer and are believed to be fairly complete. The few species belonging to the other orders listed were determined by Messrs. Nathan Banks and W. A. Clemens (Ephemeridae).

In addition to the gentlemen mentioned in the preceding paragraph, I have been ably assisted in the preparation of these lists by Messrs. J. C. Crawford, H. L. Viereck and S. A. Rohwer, who kindly revised
