brood enter the apple through the calyx eud, some enter at the stem end, and some, 

 when apples are touching, enter through the side. The well-known excreta at point 

 of entrance leaves a clue to the iiresence of the larva in an apple. The larva after 

 entering the apple penetrates to the core and there remains until full grown, when, 

 as a rule, it works its way by a different route to the side for the purposes of 

 pupation. 



The larva of the lesser apple-worm enters the apples from either the calyx or 

 stem end, and also on the side when apples are touching, in these respects resembling 

 the larva of the codling-moth. The larva; of the former, however, feed to a greater 

 extent on the surface of the apple, devouring the flesh around the calyx and stem 

 basins to the depth of y-2 inch. The larv;c undoubtedly penetrate to the core, as do 

 the codling-moth larvaj, but usually only in well-ripened apples. The larva does not 

 appear to form so definite a channel to the core as does the codling-moth larva, 

 appearing to feed more or less continuously on the flesh of the apple en route. The 

 greatest difference between the two, possibly, is the colour and shape. When full 

 grown the larva is not more than half as long as the codling-moth larva and is more 

 pinkish in colour. Furthermore, the terminal portion of the last segment is furnished 

 with a small brown structure consisting of seven teeth. 



It may be readily assumed that an arsenate-of-lead spray applied in the spring 

 and again iu July would offer the best i-emedies. 



Olethkeutes, sp. 



There is evidently a leaf-roller of the above genus at work in Lower Fraser 

 orchards which closely resembles the bud-moth in habits. The adult moth is larger 

 throughout, however, but of an ashy-grey colour. Its occurrence in the field is very 

 local, and thus far has not been observed in great numbers. 



Mr. Arthur Gibson, Chief Assistant, Dominion Division of Entomology, to whom 

 the adult was referred, believed it to be of the above genus and similar to the 

 Eastern species nim^atana. 



The Fall Web-wobm (Hyphantria ciinea, Dru.). 



In 1003 the webs of this Arctiid were very conspicuous in British Columbia.* 

 In recent years this insect has not been so common, but the well-known webs can be 

 observed at times in the Lower Fraser Valley. 



The full-grown larvje are about 1 inch long, covered with long black and white 

 hairs which project from numerous black tubercles. They feed on the foliage of 

 fruit-trees and woodland shrubs, and are confined within a thick silken web and thus 

 are readily distinguishable. Arsenate-of-lead spraying when the larva; are quite 

 small in the middle of summer, or the removal of the webs when they are more 

 mature, will prevent marked injury to the trees. 



The Tent-caterpillar {Malacosoma crosa. Stretch). 



Has not been prevalent during this jiast season. It is subject to years of preva- 

 lence and scarcity. It is apparent that parasites play an important part iu the 

 natural control of this insect. The following description of the larva is taken from 

 Prof. H. P. Wilson's report of the Division of Entomology in the Biennial Crop Pest 

 and Horticultural Report, 1911-12, Corvallis Experiment Station, Oregon, relative to 

 the species :— 



" M. Eromi. — Wliitish. irregular oval spots on middle of l)ai-k on all but tlic first 

 few segments. On either side of these siwts and somewhat separated from them is 

 a broad blue band bordered on either side by a brick-red line. Below that, on either 

 side, and reaching to the legs, is a bluish space, characterized by one blackish dot 

 on each segment marking the position of spiracles or 'breathing-holes.' Below the
