Currant Borer. (Sesia tipuliformis, L.). Mr. Swaine reported considerable 

 injury to stems of both black and red currants. In some cases the stems were 

 dying, and the leaves dried and discoloured. The larva bores in the pith sometimes 

 for over six inches ; it remaiais in the wood all winter, and in the following summer, 

 in June, the bluish-black fly-like moth emerges to lay her eggs at the buds on the 

 young wood. 



Gooseberry Span-worm. (Cymatophora ribearia. Fitch). The moths were ob- 

 served July 24th, not only on the gooseberries, but also on the currants, in the Mac- 

 donald College plantation. They fly readily m day-time when disturbed, and are 

 attracted to light at night. 



'The larvae or caterpillars are to be found in June; they are white, dotted with 

 black, with yellow stripes about an inch in length when full grown. There is but 

 one brood in a year; the eggs are deposited in July on the twigs, where they re- 

 main all winter. 



This insect is capable of doing considerable injury to the leaves of gooseberry 

 and currant. Arsenate of lead will control it. 



Currant Aphis. (Myzus ribis, L.). The reddish blisters on the leaves of 

 currants — the work of the currant aphis — were much in evidence in many Quebec 

 plantations this past season. Inasmuch as the deformations interfered with the 

 proper functioning of the leaves, considerable injury was undoubtedly done. Care- 

 ful examination for the presence of aphids on the young leaves should be marie, 

 for it is much easier to kill the insects when they are few in number and before 

 the leaves have become deformed, by applications of whale oil soap or kerosene 

 emulsion solutions. 



The Carrot Rust Fly. (Psila rosce). This insect did considerable damage 

 in some of the truck gardens about Montreal. Mr. Swaine received on July 14th, 

 from McKinnon & Son, a package of small carrots which were riddled by the 

 maggots of this insect. 



The Fall Web-worm. The unsightly webs of the Fall Web-worm were very 

 abundant both on forest, shade and fruit trees throughout the Province. Mr. J. 

 M. Fisk, of Abbotsford, reports it as prevalent in his district, and Rev. Brother 

 Liguori states that it was abundant at La Trappe. 



AN'ISOTA VIRGINIENSIS, DRURY. 

 By Thomas W. Fyles, D.C.L. 



Anisota virginiensis is one of the insects injurious to the oak. In some years 

 its ravages are very apparent. I have succeeded this year (1909) in bringing its 

 larvae through their successive stages. 



I had tried, on several previous occasions, to raise the species, but had failed. 

 I attribute the failures to the fact that oak-spray, severed from the tree, dries very 

 rapidly; and, as there were no oaks growing near my former residence, I could not 

 keep the larvae supplied with sufficiently tender food. 



In my present place of abode I am better situated, as the White Oak, Quercus 

 alba, is common in the neighbourhood. I have taken the precaution too, of placing 

 every fresh supply of food for the Anisota under the water-tap, and drenching it 

 thoroughly, before placing it in my insect breeding-cage. This plan has proved 

 very successful.
