The outbreak of the spruce budworm on jack pine in southern Manitoba and 
northwestern Ontario has apparently increased and spread considerably in 1938, 
and new areas of infestation have been reported. Hundreds of niles of forest 
showed a solid red from the air,, owing to the work of these insects, and consider- 
able tree mortality undoubtedly will result, 
field investigations on the hemlock looper in the interior of British 
Columbia indicate that the larvae were less abundant than in 1937» and there was 
a. high degree of paras it izat ion, About 4o percent of the hemlock was killed at 
Trout. Lake and near Golden, as a result of the outbreak. These are the first out- 
break records of Ellopia f is cellar ia Guen., from the interior of the Province, 
The larch sawfly continues to be abundant in many parts of the Provinces of 
Eastern Canada. Sporadic outbreaks are present in Manitoba. Another species of 
sawfly, Anoplonyx lari c is Marlatt, was found to be widespread on larch in southern 
Manitoba and in western Ontario, north of Lake Superior, but was apparently not 
injurious. Light infestations were reported in southern Ontario,
