APPENDIX E CXVII 
XVII—REPORT OF THE ENTOMOLOGICAL SOCIETY 
OF ONTARIO. 
Presented by Prof. J. M. Swaixe (Delegate). 
As a delegate from the Entomological Society of Ontario, I have 
the honour of presenting this report. 
In general the Society has had a very successful year. There 
appears to be a decrease in the membership of one or two of the Branch 
Societies, but it is to be hoped that young members may be obtained to 
carry on this work so well done by the older men, now gradually drop- 
ping out. 
The field offered by our immense territory for scientific research 
in Entomology, and for practical application of knowledge so acquired 
is almost unlimited. The great number of our insects, the ease with 
which they may be everywhere collected, their rare beauty of form and 
colouring, their complicated structures, interesting modifications, and 
remarkable metamorphoses which have thrown so many sidelights on 
problems in evolution, make the study of entomology as fascinating as 
any the young zoologist can enter. The great destruction wrought by 
so many of our insect pests renders the studies of the Economic Ento- 
mologist absolutely necessary. Along both these lines the Society is 
doing active work. 
I am glad to report that the library and collections of the Society 
are gradually increasing in value. 
The forty-seventh Annual Meeting was held at Guelph on Novem- 
ber 8rd and 4th, with a good attendance of the active members. An 
account of the papers read and of the discussions, will be found in the 
Annual Report of the Society, to appear in a few days. The following 
items from the programme of the meeting will indicate the nature of 
the work presented :—
