This dragonfly frequents sandy roads near the river, and rests 

 on the soil frequently The beautiful light green of the tenerals 

 is lost in dried or even alcoholic specimens.

10-110 jEshna eremita Scudder. 



Nordegg (altitude 4,500 ft., 120 miles west), Aug. 10, a cf ; 

 Sylvan Lake (fifteen miles west), Aug. 14, a cf ; Blackfalds (nine 

 miles north), Aug. 19-25, 3 cfs; Red Deer, Aug., 24, 4cfs; Aug. 

 27, 2 d' and a 9 ; Aug. 29, 2 9 s; Sept. 2, 2 cTs and 2 9 s; a number 

 flying in cop., Sept. 9. Last date Sept. 16, a d^. Appears to be 

 widespread and fairly common. Adult 9 s dimorphic, being blue 

 and black like male, or yellow and brown. 



11-112 Mshna interrupta lineata E. M. Walker. 



First flight of tenerals July 1. By July 13 some taken almost 

 adult. July 16 took d' and 9 tenerals at Gaetz Lake with their 

 exuviae. The latter half July, all August and first three weeks 

 Sept., lineata sw^arms everywhere, and up to the 4th week in August 

 (when A . eremita appears) the ratio of lineata to all other j^shna 

 would be at least 25 to 1. Frost at night, Oct. 1 to 7; Oct. 8, a 9 

 teneral. 



Lateral thoracic bands subject to great variation. I have 

 taken cfs with the upper two-thirds of the second band absent; 

 excepting light terminal spots, and others with both bands slightly 

 interrupted. 

 12-111 y^shna juncea Linne. 



A 9 teneral in a glade close to southeast corner Gaetz Lake, 

 August 5. There is nothing extraordinary in this record, ior jitncea 

 has been taken in /\lberta previously and might well be expected 

 to occur here, but what seems inexplainable is that careful collect- 

 ing in the same locality failed to produce others. 

 13-114 ^shna sitcJiensis Hagen. 



Red Deer, a teneral cf , Aug. 2, and cf , Aug. 11. Blackfalds 

 (9 miles north), Aug. 21, 9 ; Aug. 22, d" ; Aug. 23, a 9 and 2 cf s. 

 Last date, Red Deer, Sept. 10, a worn cf .
