THE CANADIAN ENTOMOLOGIST 97 



I am much indebted to Dr. E. M. Walker for identifying speci- 

 mens and giving me much useful advice, and also in looking over 

 this manuscript. - 



To Mr. C. B. Horsbrugh my sincere thanks are due for prac- 

 tical assistance in the collection of specimens. In this gentleman's 

 ornithological studies he has ranged the district "far and often," 

 and, owing to this careful scouting, the appearance of "something 

 new" has been almost instantly noted. 



The list is arranged according to Muttkowski's catalogue of 

 the Odonata of North America, and the second numbers refer to 

 pages. 



Unless otherwise stated all dates apply to 191G. 



Coenagrionidae. 



LESTIN.^L. 



1-37 Lestes congener Hagen. 



Tenerals appeared Aug. 4th, and by Aug. 27 adults were flying 

 in numbers. I took specimens as late as Sept. 24. 



A common insect here. 

 2-37 Lestes disjunctus Selys. , 



July 8, 1 cT and 2 9 tenerals and others observed. July 

 13-16, numbers flying; some nearly adult and tenerals. July 22, 

 many adults. August 27, still on the wing. Last date, a single 

 belated &, Sept. 14. 



Very common. 

 3-39 Lestes uncatiis Kirby. 



First appearance Jul\- 2, a cT and 2 9 tenerals, and other 

 tenerals seen by a run of still water behind Allen's House. July 

 5, a cf. " 



I do not believe uncatiis is as scarce as my scanty captures w^ould 

 indicate, but it is certainly the least common Lestes in this district. 

 I took an adult 9 in 1915, which was the first record for Alberta. 

 4-40 Lestes miguiculatus Hagen. 



I failed to note the actual first appearance of tenerals. On 

 July 19 I took 5 adult cf s, and a pair in cop., and by July 22 many 

 adults were on the wing. The insect was flying in numbers at 

 Blackfalds, August 19-25, soon after which the flight apparently 

 ceased. A common insect.
