all is perhaps that "general appearance" which'is so hard to 

 define. 



42. C. varuna, Edw. Very common around Calgary, especially on the 



level prairie, and occurring as far west as Kananaskis (Macoun); 

 Lacombe (Gregson). June and July (earliest, May 14th). A 

 larger and brighter-coloured species than the preceding, and 

 perhaps even more variable ; also differing somewhat in manner 

 of flight, owing, probably, to greater strength of wing. 



43. C. /'utta, Hiibn. Common in spruce woods near Calgary in June. 



Also at Laggan. It probably occurs at Banff, though I have no 

 record from there. 



44. C. Bea?iii, Elwes. Mountain tops, near Laggan (Bean). I took a 



fresh, but crippled, <$ there myself on Aug. 8th, 1900. 



45. Theda humuli, Harris. A single specimen brought to me in 1894, 



taken on the level prairie about twelve miles south of Calgary, 

 near the mouth of Fish Creek. I see no reason why it should not 

 be locally common. 



46. T. augusfus, Kirby. Common. May and early June. Also at Banff 



(Sanson). 



47. T. irus, Godt. Locally common near Calgary. 



48. T. eryphon, Bd. A few specimens near Billings's lumber mill. Early 



June. Banff, May 24th (Sanson). 



49. T. dumetorum, Bd. Mr. Elwes tells me he took a specimen of this 



species in the foothills, about 50 miles S. VV. from Calgary (about 

 May 1 2th, 1895 ?). 



50. T. titits, Fab. Rare and local in the hills around Pine Creek. Very 



common in foothills near Lineham's lower log camp. August. 

 Lacombe, July 28th, fairly common (Gregson). 



51. Chrysophanus xanthoides, Bdl. Very rare. Head of Pine Creek, 



July. 



52. C.thoe, Bdl. Locally common on low, wet ground amongst the 



hills on Pine Creek. July. 



53. C. mariposa, Reak. Common near the spruce. Also at Banff and 



Laggan. July and Aug. 



54. C. /tel/oides, Bdl. Common. June and July. A second brood in 



far fewer numbers in September. Both Mr. W. H. Edwards and 

 Dr. Fletcher refer my form to ftorzis, Edw. I have specimens in
