JEschna sp. 



Under this head Currie records four unidentifiable females 

 taken at Kaslo, July 8th ; S. Fork Creek, August nth ; Bear 

 Lake, July 2ist ; and at Banff, Alberta, August 16, '02. 



Tetragoneuria spinigera (,Selys). 



Common, flying over a low pasture near Langford Lake, July 

 20, '02. A number of specimens of both sexes were taken. 

 The species seems much more active on the wing than T. cyno- 

 sura. A male from Goldstream, July 16, 1899, and another 

 from Victoria have been sent me by Mr. Anderson. Previ- 

 ously recorded from British Columbia by Hagen. 



Somatochlora semicircularis (Selys). 



Widely distributed. Two males taken at Langford Lake, 

 July 20, '02, in company with Tetragoneuria. spinigera. Six 

 males at Glacier (Lake Marion), August 22, '02, Loon Lake, 

 Ainsworth, July 11, i male, and Bear Lake, July 20, '03, i 

 female (Currie). A single male specimen taken at Laggan, 

 Alberta, August 24, '02, is very much smaller than my more 

 western specimens, but Hagen (U. S. Geol. Surv. of Colorado, 

 1873, p. 591), mentions the same difference in his Colorado 

 specimens as compared with a pair from Vancouver Island. 



Somatochlora forcipata (Scudder.) 



A single male specimen taken in a small sphagnum swamp 

 on high ground at Port Renfrew, August 16, '02. Dr. Calvert, 

 to whom it was referred for comparison, writes, ' The Port 

 Renfrew specimen is nearer my New England specimens of 

 forcipaia than to semicircularis, but I am very doubtful whether 

 these two nominal species can be kept distinct." The extreme 

 western occurence of this specimen in the range of semicircularis 

 is interesting considering the doubtful validity of the latter as 

 a species. 



Cordulia shurtleffi Scudder. 



This species has only been taken in the southeastern part of 

 British Columbia where Mr. Currie found it common. Kaslo, 

 May 29th, i male, June loth, 3 males, and Loon Lake July 

 nth, 17 males. A single female was taken at Kaslo, June 7th, 

 by Dr. Dyar.
