ENTOMOLOGICAL RECORD. 

 An interesting contribution by Dr. Fletcher, entitled " Entomological 

 Record, 1901," has just appeared in the 32nd Annual Report of the 

 Entomological Society of Ontario. This, besides giving a list of the 

 active workers in Canada, includes careful notes on rarities, etc., taken 

 during the year. It is the intention of the Society to continue this Record 

 from year to year, and as this will undoubtedly prove useful to entomolo- 

 gists throughout Canada, it is hoped that collectors in the Dominion will 

 try to make it as complete as possible. Records of interesting specimens 

 captured, either from the standpoint of distribution or rarity, will be 

 acceptable,and should be sent to Dr. James Fletcher,Central Experimental 

 Farm, Ottawa. Specimens unknown to collectors will gladly be 

 identified.
