1916 ENTOMOLOGICAL SOCIETY. 145 



The President : There are so many points to be discussed in these papers 

 that I think it would be best to postpone the discussion until this afternoon, when 

 we will have more time, and when Mr. Treherne will have more time to bring out 

 certain points. 



FRIDAY, NOV. oth.— AFTERNOON SESSION. 



The President: We will now commence the afternoon session and will first 

 take up, before proceeding with the regular business, the discussion which was post- 

 poned this morning of Mr. Treherne's paper on the Cabbage Maggot. This paper 

 is now open for discussion. 



Mr. Tothill : I would like to ask if the headings " May," " June," " July,'"' 

 " August," and " September," etc., represent generations ? 



Mr. Treherne : Not in this chart. As a matter of fact, there are at least three 

 generations of this maggot in British Columbia; the first generation ends about the 

 end of May, the height of the second generation is early in July, and the third 

 generation towards the latter part of August. 



Mr. Burgess : I would like to ask Mr. Treherne if he has any definite records 

 of the maggot coming through any stage in the winter. 



Mr. Treherne : We have no larval or adult records of hibernation, but only as 

 yet pupal records. 



Mr. Gibson : With regard to the question that Mr. Burgess has asked, last year 

 and the year before we made observations at Ottawa in the hope of getting further 

 information as to how the insect passes the winter. We found the puparia abund- 

 antly in an old turnip field at varying depths, the lowest being nine inches below 

 the soil. We only found what we considered the larva of the Cabbage Maggot fly 

 in one instance, in April. The species in Eastern Canada most probably hibern- 

 ates to a more or less degree in the larval stage, in addition to the regular hibern- 

 ating form, namely, the puparium. 



The President: The only other point, I think, which might arise from this 

 paper which might be discussed is the comparative absence of internal parasites, 

 particularly the absence of Staphilinid parasites such as we find in the East. 



We will now proceed to the business meeting of this session, which consists in 

 tlie election of officers. As in the case of last year, the Council in order to facilitate 

 the proceedings of the meeting has recommended a list of officers for the guidance 

 of the meeting, and I might ask the Secretary to read the list of officers as selected 

 by the Council : — 



President, Mr. A. F. Winn; Vice-President, Prof. L. Caesar; Secretary-Treas- 

 urer, Mr. A. W. Baker; Curator, Mr. J, B. Spencer; Librarian, Dr. Bethune; 

 Directors, to be re-elected, with the exception of Division No. 6, where J. W. Noble 

 is recommended. 



Dr. Fyles : It gives me very great pleasure to nominate Mr. Winn as President 

 of the Entomological Society. I have followed Mr. Winn's work for a nimiber of 

 years, and think he is fully capable of holding the position. 



Mr. Morris : I second the motion. 



Dr. Hewitt : It has been moved and seconded that Mr. Winn be elected Presi- 

 dent of the Society. I am sure it is a matter of great gratification to all ]\rr. 

 Winn's fellow workers to see him occupying the Presidential chair. We all appre- 

 ciate the work which he has done in tlie Province of Quebec, especially in the pro- 

 duction of those excellent insect lists which he is getting up. There being no other
