Hyphantria cunea (Fall Web-worm). 

 Of all insects submitted to us for identification the web-worm 

 was most frequently sent in, and in this region at least its work 

 was the most conspicuous. Many different kinds of trees and 

 shrubs were affected, the apple being particularly subject to 

 injury. Fig. i illustrates one of several apples which were 

 taken from a web-worm nest. The caterpillars had peeled the 

 apples. 



Heterocampa guttivitta (Saddled prominent). 



After 3 seasons of very severe infestations these insects have 

 suddenly disappeared. We have seen no specimens nor have 

 any been sent in. In response to letters sent to people living in 

 districts most severely infested in former years we learn that 

 no insects of this species have been observed. 



Bucculatrix cancudensisclla (Birch leaf Bucculatrix) as a leaf 



miner. 

 This insect was reported and the larva described in Insect 

 Notes for 1909. This year the adults were abundant in June 

 upon the birch leaves. Though some cocoons were found upon 

 the trunks and branches, most of them were seen upon dried 

 leaves, sticks and grass underneath the trees and among rubbish 

 in fence corners. Some flat, translucent objects, resembling 

 the eggs of the codling moth, though of course much smaller, 

 were seen on the under side of the leaves, which may have been 

 the eggs of the Bucculatrix. Early in August no larvse had yet 

 been observed externally upon the leaves, but many leaf miner 

 trails, each with a minute larva within, were seen. Several 

 leaves containing miners were carefully examined to be sure 

 that there were no larvae upon the surface, and placed in a cage.
