28 THE CANADIAN ENTOMOLOGIST. 



Among the noteworthy facts which have been brought to 

 Hght in this study are the following; There are four or five ecdyses 

 during the larval feeding period and another ecdysis within the 

 cocoon, whereas according to Packard, whose statements have 

 been followed in all subsequent accounts, there are only there 

 moults. The period from the time of hatching to the spinning of 

 the cocoon is about 16 to 21 days in Canada, which is about twice 

 as long as given by Packard. 



The habits of the Field Vole {Microtis agresHs), in England 

 of extracting the larvae from the cocoons and feeding on them is 

 parallelled in North America, as observed by Dr. A. N. Fisher 

 of the United States Biological Survey, by the Deer-m'ouse {Pero- 

 myscus maniculatiis artemisiae). Both of these rodents are normally 

 phytophagous. Insectivorous birds are also an important aid in 

 the control of the Larch Sawfly and their protection and encourage- 

 ment is strongly recommended. 



The bulletin is illustrated by an excellent coloured plate showing 

 the adult and larva of A^. erichsonii, the effect of its oviposition 

 in the terminal shoot of the larch, and two of its most important 

 parasites, the ichneumon fly, M. tenthredinis, and the fungus, Isos- 

 pora farinosa, which attacks the larva within the cocoon. There 

 are also a number of excellent drawings and half-tones from photo- 

 graphs.

 Entomology, Central Experimental Farm, Ottawa. 



A Preliminary List of the Insects of the Province of Quebec. Part 

 I, Lepidoptera, by A. F. Winn. 



This is a most important contribution to our knowledge of the 

 distribution of Canadian insects. The list embraces nearly 1,300 

 species and is modelled upon the last edition (1909) of Smith's In- 

 sects of New Jersey. It is published as an appendix to the 

 Annual Report of the Quebec Society for the Protection of Plants. 



Brief diagnoses of each family are given and under each 

 species is a full list of localities, dates of capture and names of 

 collectors. There are also annotated lists of the collectors whose 

 records have been included and of the localities referred to. A few 

 of the commoner species are illustrated.
