 August. New to the Ottawa district. (Metcalfe). 



Odonata: — 



As mentioned above, large collections of Ottawa dragonfiies 

 were made during the past summer. Among these were many 

 species worthy of mention, but as Dr. Walker is working up this 

 material, along with other collections previously made at Ottawa, 

 for a paper for the Ottawa Naturalist, it has been thought best 

 not to publish these records here, as they will all be included in 

 Dr. Walker's article soon to appear.

MEETING OF THE ENTOMOLOGICAL BRANCH 



Held on evening of February 23rd, 1908, at Mr. Gibson's 

 house. Present: Messrs. Harrington, Young, Fletcher, Baldwin, 

 Halkett, Metcalfe, Letourneau and Gibson. 



Mr. Halkett spoke of his work during the past summer in 

 the Beaver Lake and Ou'Appelle Lakes districts of the North- 

 west. Large collections of fishes were made for the Governments 

 of Alberta and Saskatchewan, and while engaged in this work, 

 some interesting insects were collected from time to time. Mr. 

 Halkett showed three bottles containing specimens in fluid, which 

 he had collected. Most of these were aquatic insects in an 

 immature state. Some large curious larvae of a Dvtiscus was 

 noticed, which had been collected at the same time and place 

 as the perfect insects of Dyiiscns ciycnmcinctns. Dr. Fletcher 

 stated that some of Mr. Halkett's captures were of interest and
