ODONATA OF THE RED DEER DISTRICT. 

 (Continued from page 103, Vol. XLIX). 



BY F. C. WHITEHOUSE, RED DEER, ALTA. 



In the introduction to my original publication I expressed the 

 opinion that it would be slow work to lengthen the Odonata list 

 in the vicinity of Red Deer to any extent. This has proved correct 

 during the 1917 season, since I have succeeded in adding but one 

 species. From 11th to 19th July, however, 'I devoted my time 

 to collecting. at Nordegg, Alta., the site of the Brazeau Collieries 

 Ltd., situated 120 miles due west and, I should judge, just within 

 the Hudsonian zone. The result of such collecting so far as the 

 Odonata are concerned, was to add eight additional species to 

 my list, and these of such special interest as to warrant a supple- 

 mentary article. 



Dr. Walker has kindly examined the material, and given the 

 manuscript critical reading. 



As in the prior list, the first numbers are my series, and the 

 second refer to the pages of Muttkowski's catalogue. 



Coenagrionidae. 



CCENAGRIONIN^. 



28-65. Nehalennia irene Hagen. 



July 1st, north end Gaetz Lake, Red Deer, I saw a pair in 

 coitu, but failed to take them. July 2nd, at the large slough north 

 of the river, I captured a male and female. July 8th, 2 males 

 at "run" of stagnant water west of Gaetz Lake. 



All the insects were of adult colouration, and all were flying 

 down among the slough grass. I was not previously familiar 

 with this species, which probably accounts for my failure to note 

 it last year. However, I am convinced that it is not common in 

 this district — at least around waters where most of my collect- 

 ing has been done. New to Alberta list. 

 29-66 Ccenagrion interrogatum Selys. 



At Nordegg, 19th July, 30 couples of this rare insect were 

 taken in probably less than half an hour and within a space of 50 

 feet. In the morning in question my friend Mr. K. Bowman, of 

 Edmonton, was giving the Lepidoptera a short respite and me his 

 his kindly assistance. At one time we had five couples in -our
