The Flat-headed Borer, Chrysohothris femorata, is hardly found in our apple 

 trees at all. And this is interesting, for the species is very common in the neigh- 

 borhood, breeding in great numbers in fallen hickory and oak, particularly the 

 former. This spring I took scores of specimens from one fallen hickory at Hud- 

 son, a few miles from Ste. Anne's. The beetles run about over the bark on fine days, 

 mating and egg-laying, and fly very readily with a distinct " hum." Egg-laying 

 begins with us on hickory in June, and lasts until late in Julj^ although the greater 

 part of the eggs are laid by the second week of July. 



In our region at least the beetles much prefer dying hickory to apple trees in 

 any condition, and I feel confident that Mr. Chittenden's suggestion that broken 

 branches of hickory scattered about the orchard would trap most of the beetles, is 

 one well worth trying when these beetles are injurious in orchards. 



The Fruit Bark-beetle, Eccoptogaster rugulosiis, is not yet to be found in our 

 orchards. I have never taken any indeed in this Province. 



The Peach-tree Bark beetle, Phloeoiribiis Viminarus, was found in great num- 

 bers this season in wild cherry near the college. Over a score of large trees were 

 studded with the gum from its entrance holes, although the beetles succeeded in 

 breeding in very few of them. The entrance holes, and in a few places on some 

 trees the Qgg tunnels, were cut this spring but very few eggs were laid. Again on 

 the tenth of August, light coloured adults were starting tunnels in the bark. 



Next year these cherry trees will probably have a hard time of it. They had 

 enemies enough before, indeed, for the common cherry borer was altogether too 

 plentiful. 



Xyleborus dispar I have never taken in Quebec. A close ally, X. sermtus, is 

 very common in several forest trees, notably in yellow birch. 



Last spring I bred from apple-twigs sent from Cambridge, N. B., a species 

 of Olerea, which is possibly 0. tripunctata. The female cuts three rows of bites 

 and lays the egg between the bark and the wood above the second row. The grub 

 feeds at first in the dying tip, and later bores downwards through the twig. The 

 twigs are found dead during the summer and are frequently broken by storms. 

 The injury is not serious, as yet, but the species may easily become an injurious 

 pest. 



The Buffalo Tree-hopper. Ceresa huholus, has badly scarred several of our 

 young trees. The cuts were made on both the stems, which are very small, and 

 the branches. Soft maple seems to be preferred by this insect for egg-laying, and 

 until the young maples were cut away from near our orchard the fruit trees were 

 left entirely alone. 



The Bud Moth, Tmetocera ocellana, was present in considerable numbers in 

 our young orchard this season. Owing to lack of labor, early sprayings had to be 

 omitted, and the result is intimated in the accompanying photograph. A poison 

 spray, late in July, should control this insect effectively for the next season. The 

 caterpillars begin to pupate about June 10 with us. The first adults appeared in 

 the cases June 28, but empty cases were found in the field as early as the 18th. 



When our orchard is sprayed with lime sulphur, winter strength, early in 

 spring, we see little of the bud-moth, the case-bearers, or the leaf-aphides. I do not 

 say that lime sulphur controls these insects, but our exjjerience, so far, seems to 

 indicate it. 



The Cigar Case-bearer of the Apple, Coleophora fletcherella, was unusually 

 abundant on our fruit trees this summer, and apparently the same species was 

 breeding on thorn. The larvae ceased feeding about June 15th, this season, and 

 the first pupse were found on the 20th. The first adults appeared in the cages on
