reaches about two inches in length. The tents were so abundant this autumn in some 

 places that the maple trees about Knowlton and other places round Brome Lake in the 

 Eastern Townships were much disfigured. It is also very abundant at Ottawa. 1 have 

 never seen the moth yet, but have several of the larvai and pupte in my breeding cages, 

 from which I hope to get the moths next spring. 



Of fruit insects, .some of the well known pests have called for attention, as the 

 Eye-spotted Bud moth (Tniet icera ocellana, Schif. ), on the apple and plum, the Oyster- 

 shell Bark-louse {Mytilaspis poraoruvi, Bouchc), the Beautiful Wood Nymph {Eudryas 

 grata, Fab.). Fig. 4 represents the moth and Fig. .5 the caterpillar. The Codling Moth 

 {Carpocapsa pomonella, L ) and the Plum Curcnlio (Oonotrachelus nenuphar, Hbst.). 

 For these the well-known remedies have been recommended. 



Injuries of less frequent occurrence have been reported by the following : Click 

 beetles, which have injured the flowers of apples at Ottawa and of pears in Nova Scotia. 

 The Shot-borer or Pin-borer (Fig. 6) {Xyleborus dispar, Fab.) has increased and is 

 doing much injury to the apple-growing districts of Nova Scotia. Washing the trees 

 in June with a soap or lime wash, to which a little Paris green has been added, 

 will probably be found to be the best remedy. In the Niagara district I found last 

 spring that the peach trees were much infested by the Peach-bark beetle ( Phlceolribus 

 liminaris, Harr.). This is a very small Scolytid and can be easily recognized by its 

 laminate antenme. 



A new pest of the apple in Canada has been sent to me by Mr. R. Z. Rogers, of 

 Grafton, Ont., and Mr. F, J. Watson, of Okanagan Mission, B.C., namely, the Otio- 

 rhynchid beetle Anametis grisea, Horn. The beetle gnaws the bark from the twigs and 

 also eats out the buds. I have not yet worked out its life- history. 



As mentioned above, the insects which have attracted most attention during the 

 season of 1893 by their injuries are the Horn fly (fLein'ttobla serrata, Rob.-Desv.) shown 

 much enlarged at Pig. 7, and the three comaion locusts, which occur ail through 



Ontario. As was anticipated, the Horn-fly, since first noticed last year, has spread 

 far and wide over the Province, and although there has been a great hue and 

 cry amongst farmers, very few of them have systematically treated their cattle to 

 protect them from the attacks of their tormentors. The loss consi^quently has been 

 very great, owing to the falling ofl" in the quantity of milk produced at the season 

 of the year when it should have been most plentiful. -It is not probable that 

 the Horn-fly will continue to be as serious a pest after a year or two as it is 

 at present in Ontario, nevertheless it is an important matter that dairymen and 

 farmers should adopt some one of the simple and eft'eetive remedies which have been 

 discovered and practise them regularly if they wish to keep their stock in a state oJ 

 comfort and prevent an unnecessary shortage in their bank accounts. In the first place
