rather remarkable that this insect, in Nova Scotia and Prince Edward Island, attacks the 

 plum and pear as well as the apple; but at Oshawa, Mr. Worden reports that, although 

 he has plum and pear trees side by side with his apple trees, the latter alone are attacked. 



An insect which has caused considerable damage to fruit growers is the Oblique- 

 banded Leaf roller {Caca'oia rosaaea^ia, Harris). Fig. 53 represents the moth with open 

 wings ; fig. 54, with wings closed ; tig. 55, caterpillar and chrysalis. It is frequently a 

 troublesome pest on apple trees and currant bushes. This year it was sent to me as an 

 enemy of the birch, apple, pear, gooseberry, black currant, garden geranium, and a rare

interesting attack was noted in which it was destroying the seeds only of the silver maple. 

 In fact this insect seems to be a pest upon a large number of shrubs and trees, upon any 

 one of which it may develop injuriously under special circumstances. The general practice 

 of spraying fruit trees with the arsenites, for the codling moth and the leaf-eating insects, 

 will certainly reduce largely the occurrence of the Oblique-banded Leaf-roller. 



The peach orchards in the Niagara district have, during the past two years, suffered 

 seriously from the Peach Bark-beetle (Fhloeotribus liminaris, Harris). Careful experi- 

 ments have been begun in the extensive orchards of Mr. C. E. Fisher and Captain J. 

 Sheppard, at Queenston ; and it is hoped that before long a practical remedy will be dis- 

 covered. It has usually been stated that this insect attacks only injured or dying trees ; 

 this, however, is certainly not the case, for it was found in perfectly healthy and thrifty 

 young two-year-old peach trees ; although very much more abundantly in older trees with 

 rough bark. Its ravages are chiefly confined to the peach ; but, at Queenston, specimens 

 were found in both cherry and plum. There are at least two broods in the year. The 

 perfect beetles hibernate in shallow galleries in the bark ; they are active very early in 

 the spring, and on warm days, even in February and March, come out of their burrows. 

 Mr. Fisher wrote me on March 13th last : " I examined the trunks of the trees, as you 

 suggested, on a sunshiny day, and found beetles crawling with their wings set for flying. 

 As you know, ordinarily they do not appear as if they had wings ; but these had them 

 out ready for use. The presence of this insect is conspicuously evident in wet weather, 

 when enormous quantities of gum ooze from the trunks and fall to the ground. The work 

 of both the larvje and the perfect beetles seems to be confined, at Queenston at any rate, 

 to the bark. Not a single instance of penetration of the wood could be found, although 

 this latter attack is recorded by some observers. 



The remedies which have been tried are, washing the trunks with kerosene emulsion, 

 linseed oil, and whitewash containing Paris green. The results have been rather conflict- 

 ing, but there is every reason to think that before long a sure means of prevention will 

 be found. 



Another insect, which was received from the Queenston district, and al.so from Fen- 

 wick, Ont., is the Otiorhynchid beetle { Anainetis grisea, Lee). Mr. Fisher found specimens 

 upon his peach trees, but was under the impression they did not do him much harm. Mr. 

 E. S. Atkins, of Fenwick, however, sufiered more severely; he writes : " Last year they 

 killed 130 young peach trees for me, and ate out four rows of strawberries extending
