Odonata. 



Up to the present time, although a good deal of work has been done 

 spasmodically in working up the Dragon-flies of Canada by collectors in 

 different parts of the Dominion, as far as I am aware, no complete Canadian 

 list has ever been prepared. That this should be taken in hand at once, 

 is most desirable, both on account of the important role played by these in- 

 sects and also from their attractive nature. Some years ago Mr. T. J. Mc- 

 Laughlin worked up the species of the Ottawa district, and Dr. E. M. 

 Walker, of Toronto, has recently made extensive studies of the Odonata of 

 the whole Province of Ontario. Up to the end of last year he had listed 

 65 species, and a few others have been added during the past summer. A 

 list of 37 British Columbian species prepared by Prof. Raymond C. Osburn, 

 of New York, is reproduced from Entomological News in the September 

 Bulletin of the British Columbia Entomological Society. As already men- 

 tioned, Mr. E. B. Williamson, of Bluffton, Ind., made a short trip into 

 Northern Ontario during the past summer for the special purpose of col- 

 lecting Odonata, and Mr. Mcintosh has collected in New Brunswick. 



Entomologists will be pleased to learn that Dr. E. M. Walker has under- 

 taken a complete revision of the genus ^Eschna in North America. He 

 thinks that "the determinations of the species have been to a large extent 

 guess work, and that not sufficient account has been taken of the females 

 and of the colour markings." Dr. Walker writes: "I have already come 

 to pretty definite conclusions as to the limits of the species, and find there 

 are several more than has been believed by the best authorities to be the 

 case. Females and colour pattern prove to be of great importance and in- 

 dividual variations within the species but slight. I am going to verify as 

 far as possible my conclusions in the field next summer, but would like i(\
