The forest tent caterpillar caused considerable complete defoliation of 
forest trees in the New England and Middle Atlantic States,, and westward to 
northeastern Minnesota. 
Eggs of. the gypsy moth started hatching in Maine and New Hampshire early in 
May. This insect is causing extensive and serious defoliation in many parts of 
Massachusetts* 
The larch case hearer Kas severely injuring larch in New England and 
eastern New York. 
The anobiid beetle Platybregmus canadensis Eisher was reported to be dam- 
aging flooring for the first time in the United States. It was originally des- 
cribed from Ontario, Canada, in 193^»

Hatching of the lesser migratory grasshopper was first noted in Manitoba 
on May 10. Hatching of the eggs of this species and of the two-striped grass- 
hopper was generally slow and irregular. Heavy rains early in June retarded 
grasshopper development. No crop damage and no need for control measures had 
developed by mid-June, but toward the end of the month the insects were causing 
some alarm in southwestern Manitoba, and damage is expected if dry weather sets 
in. In Saskatchewan the lesser migratory grasshopper began hatching in the 
Estevan district on May 8. Egg mortality of this ppecies was generally low. 
The first nymphs of the clear-winged grasshopper were observed on May 10, near 
Unity, Saskatchewan, and hatching was in full swing in northwestern districts 
by the end of May and was proceeding in stubble generally, although mofe ir- 
regularly. Fully half the eggs in all infested areas had hatched by June 1. 
In western Saskatchewan an egg mortality of 60 percent of this species was ob- 
'served. Possibly a fungous organism was involved. By the third week of June 
grasshopper hatching throughout the Province was practically complete. Devel- 
opment was very irregular but more advanced in northern sections where adults 
were beginning to appear. Up to mid-June, cool weatteer had restricted losses, 
and control efforts were considered adequate where c*op prospects were good. 
In Alberta hatching of the lesser migratory grasshopper began late in April in 
light sandy soil areas in the Red Deer Valley. Owing to uneven egg development » 
the hatching period extended over several weeks. It, was about -40 percent com- 
plete, in east-central Alberta by May 31. Some crop losses had occurred early 
in June, but these were checked by control measures, * and to some extent by 
rains. Late in June grasshoppers were becoming more active, with hot weather, 
but damage was still light* In southern British Columbia, in the Midway dis- 
trict, the clear-winged grasshopper was hatching the last week of May and a 
very heavy infestation has developed. The grasshopper situation is expected to 
be acute in the Province this season, although the insects were late in hatch- 
ing. 
Reports of serious cutworm damage have been largely confined to the Pro- 
vinces of Alberta and Saskatchewan. The pale western cutworm was causing injury 
to fall wheat and rye at Lethbridge, Alberta early in April, the earliest re-
