The large caterpillars of the Cecropia Emperor Moth were remarkably 

 abundant this year on apple and crab trees at London, Brantford and Guelph. 

 Being so large and voracious they consume the foliage very rapidly and 

 soon strip a branch of its leaves. In Toronto Mr. Nash found it in con- 

 siderable numbers on spirsea, as many as a dozen being seen on one bush in 

 August. This handsome insect cannot be classed amongst our noxious 

 species, as it rarely occurs in any numbers, being kept in check by its para- 

 sitic enemies; the cocoons in winter are also attacked by woodpeckers, who 

 perforate the silken wrappings and suck out the liquid contents of the 

 chrysalis. 



Amonar other insects affectinar the apple mav be mentioned the Common 

 Eye-spotted Bud-moth (Trnetocera ocellana) which we always have with us. 

 The Apple Bucculatrix {B. pomifolieUa) — hg. 15 — mining the leaves, was

abundant on some trees ; its narrow, white cocoons were found in numbers 

 on the twigs where the tiny caterpillars had attacked the foliage; at St. 

 Catharines it occurred in injurious numbers. 



An unusual attack upon the foliage of Quince trees was reported by 

 Mr. Alister McKay, of Chatham. Large numbers of the leaves were found 

 to be riddled with roundish holes in September, and in October the singular 

 flat oval cases containing the chrysalids were to be seen in numbers attached 

 to the leaves and to boards standing on end near the trees. The parent insect 

 is a very beautiful minute moth called the Resplendent Shield-bearer 

 (Aspidisca sple7xdoriferella) which comes from the cocoons in May. The 

 accompanying illustration (fig. 16) shows the insect in its various stages;
