REPORT OF THE SOCIETY 19 



the members quite a number of new ways of keeping the larvae and caterpillars 

 of many insects with their natural colors. Here is one of the formulas: 



Cane sugar ; 10 parts 



Acetic acid 5 parts 



Formaldehyde 2 parts 



Distilled water to make 100 parts. 



Plunge the specimens in some of the liquid and after 24 hours, throw this 

 away and change to another bottle of the same liquid. Repeat this a third time 

 at an interval of 24 hours. Cork well after the third time. 



We were favored with an excellent paper by Mr. N. Criddle. His paper 

 was on the subject of "Some insect problems in the Prairie Provinces." 



Mr. J. D. Tothill, Dominion Entomological Laboratory, stationed at Frede- 

 ricton, N.B., gave us an interesting talk on the results of the Recovery of the 

 Brown-tail Parasite, Compsilura, in New Brunswick. This valuable parasite, 

 imported through the Entomological Branch at Ottawa, is now part of our 

 Canadian fauna. This is a very encouraging fact that crowns with success a 

 very worthy cause. 



At the Evening Session, Dr. Creelman addressed the assembly and was 

 followed by Mr. J. A. Morris of Peterborough, who, as usual, delighted his audience 

 with a very excellent paper on "The Life-History of a Hobby-Horse." The 

 popular lecture, this year, was given by Mr. John J. Davis, of the United States 

 Bureau of Entomology, West Lafayette, Indiana, who closed the day by speaking 

 on "Present Day Problems in Entomology." Mr. Davis would like to see more 

 effective co-operation between all agriculturists, especially in the wide field of 

 Entomology and Pathology, and the farmers. Experience, he stated, has taught 

 us that the promiscuous mailing of Bulletins is a waste. 



On the following day, the President of the Society, Mr. L. Caesar, opened the 

 meeting by an address on "Insects as disease carriers." Dr. S. Hadwen, of 

 Ottawa, showed us interesting slides on Oestrids and Bot flies, contributing more 

 knowledge on that practical subject. Mr. Arthur Gibson spoke on the Cabbage 

 Maggot, Mr. F. W. Sladen on Bees, Professor Lochhead, our own President, on 

 "Some Early Chapters in Entomology." Dr. Walker, of Toronto, on "The Geni- 

 talia of Primitive Insects." Mr. Ross gave us more details on the Pear Psylla 

 and Professor Caesar a synopsis of the means of getting rid of the Apple Maggot. 



We came back much pleased with a most interesting meeting.
