From about the middle of August until the early part of September Birch trees of all kinds 

 were badly attacked by the larvae of the Birch Bucculatrix (Buccidatrix Canadensisella. ) (Fig. 12 



shows an allied species which attacks apple- 

 trees.) This attack caused widespread attention 

 and as the larvae were so abundant they soon 

 stripped the trees of their foliage. Towards the 

 end of August the attack was most noticeable, 

 and at this time the leaves were quickly falling 

 from the trees. 



From the collector's standpoint insects were 

 very scarce in this district during the past sea- 

 son. I, therefore, did not succeed in taking 

 many species which call for special mention. I 

 have during the year continued my work at 

 breeding and inflating larvre and the following, 

 which ate shown in a case I have brought to the

meeting, are some of the species I have raised or collected the larvit of ; 

 Fapilio turnus — larva, chrysalis and imago ; common.

Grapta comma — dark and light forms of larva, chrysalis and imagoes. Larvae were rather 

 common this year on hop. 



Philampelus achemon — larva (fig. 14), pupa and imago (fig. 13). This year I collected about 

 11 larvae on wild Virginian Creeper.
