1907 ENTOMOLOGICAL SOCIETY. 23 



The following- notes, however, are submitted : 



The small White Cabbage butterfly {Pontia rapm), was very plentiful 

 in the district and its ravages in neglected gardens could be easily seen. It 

 was particularly troublesome towards the end of August. On August 22nd 

 I visited a large garden at Billing's Bridge, near Ottawa, and here the in- 

 jury was to cauliflowers. The insect-powder remedy is such a simple one 

 that I cannot understand why growers of cabbages and other plants which 

 are attacked, allow this insect to destroy their crops. 



The Colorado Potato beetle (Leptinotarsa decemlincata) was particular- 

 ly abundant in many potato patches. Although the season was a poor one 

 for potatoes, those growers who sprayed with the poisoned Bordeaux mixture 

 were well rewarded. 



Grasshopp'ers were very numerous at Meach's Lake, Que., near Ottawa. 

 In one garden of a friend of mine all the flowering plants were completely 

 destroyed, while in another large garden about half a mile away flowering 

 plants were saved by allowing chickens to run in the garden. This is 

 another instance of the value of poultry in reducing the numbers of injur- 

 ious insects. 



When these domestic animals once acquire the habit of feeding on grass- 

 hoppers and cutworms, they become of so much more value to the owner. At 

 Billing's Bridge grasshoppers were also noticed injuring cauliflowers and 

 other crops of vegetables. 



The Fall Webworm and the Yellow-necked Apple-tree caterpillar appear- 

 ed in considerable numbers and their injuries were very apparent through- 

 out the district. Where these insects were troublesome on shade or orna- 

 mental trees, the simple remedy of cutting off the infested branches was re- 

 sorted to. Halisidota caterpillars of two species, the Hickory Halisidota 

 (Hah'sidota caryoe) and the Spotted Halisdota {H. mactdata) were responsi- 

 ble for much injury to the foliage of many trees and other plants in late 

 August and early September. At Hockliffe Park, near Ottawa, the cater- 

 pillars of the Spotted Halisidota were abundant on willows, basswood and 

 Wild Eose. 



Several colonies of the Black. Walnut worm {Datana integerrima) were 

 observed as very destructive to cultivated Black Walnuts and Hickories. 

 This insect, however, cannot be usually considered an injurious one at Otta- 

 wa as it does not occur in sufficient numbers to do serious damage. Cut- 

 worms, while troublesome in some gardens, were not responsible for very 

 much damage, as far as I know, in the district, during the past season. The 

 poisoned bran remedy is becoming more widely used every year. 



Eoot Maggots, too, were not in such numbers as to cause much anxiety 

 to market gardeners during the season of 1907. 



Division No. 2.— Midland District. By C. E. Grant, Orillia. 



The year of 1907 was a remarkably backward season ; on the 27th of 

 May I walked home in half an inch of snow and the wind blowing a bliz- 

 zard, then a short three months of summer which was excessively dry. 



No very serious complaints of insects were reported to me. 



There were, however, widespread complaints of the Buffalo-beetle, 

 which has apparently invaded most houses and no efficient remedy seems 

 to have been found or else the remedy is not properly applied. 



The currant saw fly and the codling moth were also very bad this year 

 and the apples here (in fact most fruits) were small, therefore the crop was 

 poor. The cutworms were also rather plentiful.
