A comparison of this list with Winn's Quebec list brings out some interesting 

 facts. The InitterHics of Alberta (116 species) outnumber those of Quebec 

 (84 species) by more than one- fourth of their number, while in all the other 

 groups the Quebec list leads. There are more than twice as many Sphingid;e 

 in Quel)ec than in Alberta (33:15), five times as many Saturnioidea (10:2), and 

 six times as many Sesiidae (12:2), while the differences in the Arctiidae (includ- 

 ing Lithosiidie and Nolidae— 37:34), Noctuidie (488:428) and Geometridie 

 (193:167) are relatively slight.

The History of the Codling Moth in British Cohimhia. — By R. C. Treherne. 

 Vol. 6, No. 1, Jan., 1919. 



Since 1905 at least 12, probably 13, distinct outbreaks of the codling moth 

 ha\'e occurred in British Columbia at widely separated points, a inarked in- 

 crease in their numbers having taken place since 1912, coincident with a noted 

 rise in the fruit yielding capacity of the orchards of this Province. Vigorous 

 action has been taken by the Pro\incial authorities to eradicate these out- 

 breaks, the Dominion Entomological Branch acting in an advisory capacity 

 during the past three years. At the close of 1918 codling moths are believed to 

 e.xist in small numbers in the \icinity of Vernon, Okanagan Landing and Victoria, 

 but have been nearly or cjuite exterminated from the other localities where out- 

 breaks have occurred. 



The operations undertaken wherever outbreaks are reported are described, 

 including the procedure followed in the disposal of fruit in infested areas.
