The Mexican bean beetle is reported from Adams, Highland, Pike and Scioto

OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR AUGUST, 19 23. 
Aphids generally are unusually numerous this year on all kinds of vege- 
tation in Nova Scotia, and much apprehension is being shownv • on the part cf or- 
chardists and growers with regard to the numbers of several species of economic 
importance. The green apple aphid is more numerous in the Annapolis Valley than 
it has oeen since 1913. The rosy aphid is likewise very numerous. The potato 
aphid and the turnip aphid are very abundant, but a fungous disease induced by 
warm, cloudy weather during the first two weeks of August checked their numbers 
to a very considerable extent. 
The red spider has seldom, if ever, been more injurious to small fruits 
than it has been this year in the Niagara district of Ontario. Black currants 
and raspberries are suffering particularly, the foliage turning brown, becoming 
scorched, and the fruit crop in many instances be ins almost a complete failure. 
The rose leafhopper, which occurred in outbreak form in apple orchards 
in eastern Ontario early this season, has oeen reduced to insignificant proportions 
through natural agencies . Parasitism has oeen very heavy. 
The lesser migratory grasshopper continues in the ascendancy at many 
points in Canada. The outoreak in the southern Okanagan Valley of British Columbia 
is particularly severe and seems to be extending into more northerly points in the 
same valley. In southern Aloerta and Saskatchewan the outbreak is continuing, 
engendered to seme extent by migrations from certain points in northwestern United 
States. In Prince Edward Island this species has for the second year in succession 
caused a great deal of trouble in Kings and Queens Counties, covering an area of 
approximately 100 square miles. 
The clover-seed chalcid is proving to be more widely distributed in 
southern Alberta than formerly. In some fields at leastlv/,0 per cent of the pods 
contain larvae. 
The fall webworm appears to be numerous everywhere in southern Manitoba 
this year and also in the eastern townships of Quebec. 
The spruce budworm is occurring abundantly in the neighborhood of Vic- 
toria, B.C. A heavy outbreak is expected from this insect next year in this 
locality and at other points in the coast sections. 
The black walnut caterpillar has occurred in outbreak form in western 
and southwestern parts of Ontario. Many walnut trees throughout this area have 
oeen completely stripped of foliage. 
A syrphid, close to Eumeru s s trig at us Fallem , has been reared from the 
roots of iris infested with the iris borer from Toronto, Ont . In all probability 
this insect is European in origin.
