THE CANADIAN ENTOMOLOGIST. 209 



Ontario, Mr. H. F. Hudson is conducting an investigation on an outbreak 

 of the Chinch Bug which proved very destructive to grass land last year. 

 He is also making observations on Wireworni and White Grub. 



In British Columbia Mr. R. C. Treherne, in addition to studying 

 certain more serious apple pests, is investigating the Strawberry Weevils, 

 chiefly OtioryticJws sulcatus, which are responsible for serious losses to 

 strawberry growers not only in British Columbia but also in other regions. 

 With a view to studying similar conditions elsewhere he is visiting the 

 States of Oregon and Washington. For the present season the field 

 laboratory is located at Hatzic, B. C. 



Although no field work is being carried out in the Western or Prairie- 

 Provinces it is hoped that work will be commenced there in the near 

 future, as there are several insect pests affecting cereals and field crops 

 demanding attention. 



Since his appointment as Assistant Entomologist, Mr. J. M. Swaine 

 has made an excellent start in the Division's work on forest insects. In 

 May he visited the Riding Mountain Forest Reserve in Manitoba for the 

 purpose of liberating the parasites of the Larch Sawfly, which were impor- 

 ted from England, and also to study the native Bark-beetles. Other parts 

 of Eastern Canada are being visited during the present season. 



Mr. Gibson has been continuing his work on Cutworms^ studying 

 especially species from Alberta where Cutworms, have been responsible for 

 very considerable losses in certain sections of Southern Alberta where 

 growing grain was completely destroyed. He also superintended the work 

 on Root-Maggot control, this being the third season during which these 

 experiments have been carried on. 



The distribution of Ticks in Western Canada, with especial reference 

 to the Rocky Mountain Spotted Fever Tick, Dermacentor venustus is being 

 studied with interesting results. In the campaign against the House-fly 

 which is now in full swing in various.cities, especially in Eastern Canada, 

 the Division is continuing to provide much powder and shot. 



It is, we hope, hardly necessary to add that any assistance which 

 local entomologists are able to render us in the various branches of work 

 outlined above will be most welcome. This is especially the case where 

 we are working out the distribution of certain insects, The territory which 

 we have to cover is so great in extent that we wish to enlist all the co- 

 operation possible. C. G. H.
