NATURAL HISTORY, TORONTO REGION 
inhabiting sandy fields and open sandy woods High 
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
