350 THE CANADIAN ENTOMOLOGIST 



RECENT CANADIAN PUBLICATIONS. 



Under this heading we propose to present notices from time 

 to time of entornological pubHcations by writers residing in Canada, 

 or such as appear in Canadian periodicals, whether by Canadians 

 or not. Exceptions will be made in the case of papers published 

 in the Annual Reports of the Entomological Society of Ontario 

 and the present journal. Short articles or those of a popular 

 character will, as a rule, be merely listed. 



Authors will greatly assist the Editor by sending him copies 

 of their publications for notice in this section. 



The following papers were all published during the present 

 year: 



Proceedings of the Entomological Society of Nova 

 Scotia for 1917. No. 3. Truro, January, 1918. Pp. 1-96. 



This excellent report gives ample evidence of the vigorous 

 condition of the youngest branch of our Society, and is a most 

 creditable production. It contains no less than sixteen papers by 

 ten contributors, dealing with a variety of subjects, both economic 

 and faunistic, and these are illustrated by 15 plates, most of them 

 half-tones of fine quality. 



The following papers are mainly of economic interest:
