infested and likely-to-be-infested areas, was completed in May. We found that 

 the area in New Brunswdck had increased enormously, although the infestation 

 was very lightly distributed. In Nova Scotia the area and infestation were about 

 the same. 



During the past year also we have continued and extended the work of im- 

 porting parasitic enemies of our worst insect pests. For the purpose of importing 

 the parasites of the Larch Sawfly, the chief of which is the Ichneumon, Mesoleius 

 tenthredinis, I visited the English Lake District in January and discovered a 

 locality where I found the cocoons of the Larch Sawfly well parasitized. Arrange- 

 ments were made for the collection of the parasitized cocoons and these were 

 shipped to us in the spring. Mr. Swaine then took them with him to the Eiding 

 Mountain Forest Eeserve in Manitoba where we are attempting to establish them. 

 Our reason for establishing them on this western point is that this point appears 

 to be the present western limit of the spread of the Sawfly. I should say in 

 passing that I previously referred to the chief Ichneumon parasite of the Larch 

 Sawfly as Mesoleius aulicus, but it has since been found that the species which I 

 studied was a new species to which the name Mesoleius teyithredinis has been given. 



Turning from our work in the Division of Entomology to pro- 

 vincial matters, it is a matter of great gratification to us all to be 

 able to record the development of entomology in the Provincial Depart- 

 ments of Agriculture as evidenced by the appointment of entomologists 

 in three provinces. In British Columbia, Mr. W. H. Brittain has been 

 appointed as Plant Pathologist and Entomologist, and we hope that he will 

 be able to find time to devote to insect pests as well as plant diseases, although both 

 offer enormous fields for investigation in British Columbia. In Nova Scotia Dr. 

 Eobert Matheson, late of Cornell University, has been appointed Provincial Entom- 

 ologist, and we are delighted to have succeeded by this appointment in bringing 

 back so hard working an entomologist to his native country. Mr. Caesar has been 

 appointed Provincial Entomologist for Ontario, although T understand that the 

 appointment has not yet been officially confirmed. His colleagues and friends will 

 be glad that his services for Ontario have thus been officially reco.gnized. With 

 these provincial appointments and the prospect «f co-operation between the 

 Division of Entomology at Ottawa and the Provinces, I look forward to a rapid 

 and useful extension of our work in the near future. We have an enormous field 

 to cover ancl we shall still have to spread ourselves out in order to touch even the 

 borderland of what lies before us. 



Before concluding my address, T shall like on behalf of the Department here 

 to extend to you all a most cordial welcome. It is a source of unusual pleasure 

 for us to see gathered together representatives from so many provinces. We have 

 representatives from Nova Scotia, New Brunswick, Quebec and Ontario, and papers 

 will be read from members in Manitoba and British Columbia Avho are unable to 

 be with us. The coming together in this way of entomologists from so wide an 

 area cannot but result in discussion which will be of the greatest value to all of us 

 in our work. I am sure that we shall all go away from these meetings feeling that 

 our deliberations have enabled us to advance in our work, so increasingly important 

 in helping on the development and increasing ihe productivity of this great country.
