TWENTY-FIRST ANNUAL REPORT 
OF THE 
ENTOMOLOGICAL SOCIETY OF ONTARIO. 
To the Honourable the Minister of Agriculture: 
Sir,—In accordance with the provisions of our Act of incorporation, I beg 
to present herewith the twenty-first annual report of the Entomological Society 
of Ontario. 
The report contains an account of the proceedings of our annual meeting for 
the election of offi¢ers and the transaction of the general business of the society, 
which was held in the city of London on the 27th of August, 1890; it includes 
also the audited financial statement of the Secretary-Treasurer, the reports of the 
Council and Montreal branch, the President’s annual address, ete. 
Ihave also the honour to submit with the foregoing, several illustrated 
papers contributed by our members on injurious and other insects, which have 
been specially prepared for the information of the public, and are intended to 
assist our farmers and fruit-growers in contending with their insect enemies. 
The Society’s monthly magazine, The Canadian Entomologist, has been 
regularly and promptly issued during the past year, and has just completed its 
twenty-second volume. It continues to receive contributions from all the most 
eminent Entomologists in North America, and to circulate in all parts of the 
world. During the past year it has been found necessary to issue more than 
twenty extra pages in order to find space for the many valuable articles which 
have been furnished the editor. 
It is a matter of profound thankfulness that our province, during the past 
year, has escaped from any serious insect attack. Those that have been specially 
noticeable are referred in the President's address, or described in the papers that 
follow. 
I have the honour to be, Sir, 
Your obedient servant, 
W. E. SAUNDERS, 
Secretary.
