NATURAL HISTORY, TORONTO REGION

 Park is still a good locality, and many other arena- 

 ceous forms, particularly among the beetles, may be 

 taken on Toronto Island. Aquatic species may be 

 collected in Grenadier Pond (High Park), the Hum- 

 ber River, Etobicoke Creek, the upper part of the 

 Don and in the lagoons of Toronto Island. Large 

 quantities of material of many species, especially 

 beetles, are sometimes cast up on the beach drift 

 of the Island. 



For a city of its size comparatively little collect- 

 ing has been done about Toronto, and some of the 

 smaller orders have been wholly neglected. The 

 largest general collection is that of the late Dr. Wm. 

 Brodie, now in the Provincial Museum. The list of 

 Hymenoptera is for the most part merely a list of 

 the named species in this collection. It is believed 

 that they were authentically determined, as Dr. 

 Brodie was in the habit of sending his specimens 

 to Ashmead and other specialists at Washington for 

 determination. This is certainly the case in regard 

 to the Chalcidoidea. The list of Cynipoidea and 

 the gall-forming Tenthredinidae were for the most 

 part furnished by Dr. A. Cosens. For the list of 

 Coleoptera I am indebted to Mr. R. J. Crew, who 

 has collected beetles extensively about Toronto. His 

 specimens were determined by Prof. Wickham. The 

 Lepidoptera have been kindly listed by Mr. A. 

 Gibson, of Ottawa, his list being mainly based on 

 his own collections. The Diptera have not been
