56 THE REPOET OF THE No. 36 



Pettit, the Provincial Apiarist, tells nic that in some parts of Ontario bumble-bees 

 are scarce, and that a farmer in one of these districts got a splendid crop of red 

 clover seed by procuring nests of ibumble-bees and putting them around the field. 



At the close of the lecture a vote of thanks to Mr. Sladen for his interesting 

 and instructive address was proposed hj Mr. Grisdale and seconded by Prof. 

 Lochhead. 



SECOND DAY'S SESSION— WEDNESDAY, 20th, 1912. 



At 9.15 a.m. the members met in the Carnegie Library, and the session com- 

 menced with the election of officers for 1912-1913. A list of these is given on 

 page C. 



An interesting address was then delivered by Mr. J. H. Grisdale, Director of 

 the Dominion Experimental Farms, who spoke of his early entomological associa- 

 tions and of his warm friendship for the late Dr. James Fletcher, by whom his first 

 real interest in entomology was awakened. He referred to the importance and 

 value of the work that is now being done in economic entomology in Canada, 

 particularly by the Division of Entomology, and of the rapid development of the 

 Division since the appointment of Dr. Hewitt as Dominion Entomologist. He 

 expressed his keen interest in the work of the Society, and his readiness to do any- 

 thing in his power to assist in the advancement of economic entomology. 



The remainder of the forenoon and the afternoon were devoted to the reading 

 and discussing of papers, all of ^vihich appear in the following pages. 



Dk. Hewitt: Owing to Mr. Tothill's illness, I shall read his paper, as I am 

 liaturally well acquaimted with the work wliich Mr. Tothill has been carrying on. 



As I told you when we last met. we proposed to start the introduction into 

 Canada of such parasites as we could obtain of the Brown-tail and Gipsy Moths. 

 Experiments in this direction are now being carried on and this season we have 

 instituted field stations for the purpose ; one has been established in New Brunswick 

 and one in Nova Scotia. Mr. Tothill's Avork in New Brunswick has been directed 

 especially to the question of the introduction or the possibility of the introduction 

 of parasites of the Brown-tail Moth. The Brown-tail Moth in New Brunswick 

 has spread over a very large area during the past two seasons, and it seems to us 

 that the only method of combatting this pest was to import the controlling parasites 

 of the insect. With that object in view, I made arrangements Avitli Dr. Howard, 

 of the United States Bureau of Entomology which, as you know, during the past 

 few years have been importing from Europe and Asia parasites of the Gipsy Moth 

 at an enormous expense. We are, therefore, able to make use of the results of 

 the work of tlie United States Department of Agriculture in this connection, in 

 view of Dr. Howard's willingness to assist us in this manner. One of the two 

 insects that we could make use of is a Carabia beetle which is predaceous on the 

 Brown-tail and Gipsy Mbth larvfe. It also feeds on the caterpillars of certain 

 other native insects. You will thus realize that this insect is extremely useful 

 on this account. Therefore, we decided to import that insect as one of the two 

 yaluable enemies in checking the Brown-tail Moth. The other insect parasite is a 

 fly, a Tachinid, which Mr. Tothill has studied specially; this is parasitic on the 

 larvffi of the Brown-tail Moth and the Gipsy Moth and other native insects. Mr. 

 Tothill's paper is as follows.
