CCENAGRIONIN.E. 



5-55 Enallagma calverti Morse. 



A number of my 1915 captures were labeled by Dr. Walker 

 " cf calverti'' and " 9 calverti or cyathigeriim." The insects seem 

 very similar in appearance, season and habits, but the cf s appear 

 to differ constantly in the form of the superior appendages. My 

 dates read: teneral cf s June 7; adult d's June 24, and a pair, in 

 alcohol, July 2; both fully adult. Another pair taken in cop., 

 July 23. Common. 

 6-57 Enallagma cyathigerum Charpentier. 



On the wing early in June and adult by 24th of that month. 

 I have pairs taken in cop., June 25, July 15, July IG. By 4th week 

 in July principal Alight was'over, but belated individuals appeared 

 later. I took a cf as late as August 27. Common. 



7-( ) Ccenagrion angidatum E. M. Walker. 



On July 4 I took a g?", fully coloured, at Gaetz Lake, fiying 

 with C. resolutum. Innisfail, July 6, hundreds fiying with resolutum 

 by stagnant slough. Red Deer, July 8, Gaetz Lake, o^ and 9 ; 

 July 13, d" and 9 ; July 19, 2 cfs; July 22, a cf . A stagnant 

 slough rather than a considerable body of clear water appears to 

 be the truer habitat of the nymph — which is at present unknown. 

 It was useless to work the slough on the occasion mentioned as 

 heavy rains had fallen. The slough was flooded and all exuviae 

 would have been washed from the reeds. New to the Alberta list. 



8-66 Ccenagrion resolutum Hagen. 



'First appearance 1916, May 26, tenerals of both sexes. By 

 June 15 in full colour. Numbers in cop., June 25, July 4, July 16, 

 July 19. Shortly after the last date the flight ceased. Common. 

 Gaetz Lake, Red Deer, and Innisfail near stagnant slough.

GOMPHIN^. 



9-85 Ophiogomphus severiis Hagen. 



In 1915 I took a number Aug. 30 to Sept. 7, but more thorough 



collecting in 1916 proved that severus appears in mid-July. My 



dates are July 13, a teneral cf ; July 14, a cf ; July 17, 9 ; July 18, 



9 ; Aug. 4, 3 cfs — one a teneral; Aug. 5, cf and 9 ; Aug. 6, a
