during the month. This is the first serious infestation of this insect in the 
southeastern part of the United States. 
An outbreak of the serious disease of horses known as encephalomyelitis 
continued in Maryland, Delaware and Virginia. The fact that this disease has 
"been transmitted experimentally by mosquitoes has directed much attention to 
the mosquito question. There has emerged from the salt marshes of the Central 
Atlantic States a series of heavy broods of salt marsh mosquitoes, which have 
given abundant opportunity for the spread of the disease if these species are 
concerned. 
THE MOKE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA EOR THE ■ 
PERIOD, JULY - SEPTEMBER, 1933. 
The serious outbreak of grasshoppers in the three prairie Provinces of 
Manitoba, Saskatchewan, and Alberta caused great damage to wheat and other 
crops over a very wide territory. Increase in numbers and migrations 'involved 
much territory that previously was only lightly infested. In some districts 
the situation was so threatening as to cause many farmers to cut their crops 
on the green side to minimize losses. After the grains had been liar vested 
the grasshoppers turned more to weeds, grasses, garden truck, and other late 
crops, and their ravages were still continuing early in September. Reports 
indicate that very large areas will be even more heavily infested in 1934. 
In British Columbia, where grasshoppers have been at a low ebb in recent years, 
there are evidences of a general Increase that may presage a further outbreak 
in this province. In eastern Canada grasshopper infestations continued moder- 
ate in most localities. 
A more extensive outbreak of the pale western cutworm is expected in 1934, 
in Alberta and Saskatchewan, than occurred this spring. 
Very heavy infestations of the wheat stem sawfly and an unusually high 
degree of loss of wheat infested by this species were observed in a number of 
districts in Saskatchewan. Sawfly damage was also evident in south-central 
Alberta. 
The wheat stem maggot again caused some injury to wheat in Manitoba, the 
damage ranging from less than 1 percent in some areas, to nearly 15 percent in 
others. Practically all parts of the province were affected. 
Heavy infestations of second-year white grubs occur over an area of at 
least 5,000 square miles in eastern Ontario. Timothy meadows and crops such 
as strawberries and corn have been seriously damaged. In southern Quebec, 
adult beetles are, more numerous in the soil than in 1930, and hence a large 
flight is anticipated over much of agricultural Quebec in 1954. No injury to 
the roots of common farm crops will occur until July of that year. 
The Colorado potato beetle was widespread over settled areas of the . 
Prairie Provinces, notably in Manitoba and southern Alberta, where i: ore

The beet webworm was conspicuously abundant in Saskatchewan, p : ilarly 
in the northern settled portion of the Province. It attacks vegetable a
