to hemlock many other coniferous trees and deciduous plants are affected. 
Severe outbreaks of the satin moth and tent caterpillars have 
resulted in the total defoliation of. hundreds of acres of brash and Cot- 
tonwood stands in the vestern half of the lower Fraser Valley, Britis 
Columbia. In the Lloydminster district, Saskatchewan , the forest tent 
caterpillar caused probably total defoliation of asotn poplars. The out- 
break appears to be extending eastward each year and parasites are gradu- 
ally checking the tent c.-terrjill-rs in older infestations. 
In the Barkerville and Stanley region of British Columbia, the in- 
festation of the soruce budworm has been retarded by cold veather and rain. 
The tussock moth Heme roc amp =■ -oseudotsu^ata McD. , v/hich in 1925 
was reported around a ranch house in the B. X. district, 5 miles north- 
east of " r fcrnon, British Columbia, has spread considerably and is now at- 
tacking areas of Douglas fir on the mountain side. 
Adults of the fall webworm are unusually abundant in the lo'-er 
Fraser Valley, British Columbia, and a severe outbreak of this defoliator 
is in prospect later.-in the year. 
Reports from Mova Scotia, Ont-rio, Manitoba, Saskatchewan, and 
British Columbia indicate that mosquitoes are much less troublesome in the 
Dominion this year than in 1928. This is probably largely due to sub- 
normal rainfall in earlv summer.
