the higli peaks of the Rockies, where she collected during that season, and 

 says: "I never found the female lower down, as was the case with 

 astarte'^ She also met with it commonly during her trip far north of 

 Laggan last summer. On July i6th last I caught nine specimens on 

 Piran, including one or two females, during cold weather, with very little 

 sunshine. During a short glimpse of shine, if one did not get up in sight 

 of its own accord, I could occasionally stalk one up, and marking it down, 

 often found it sleepy and easy to catch. One that I marked, I dug out 

 from amongst the stones nearly two feet down. On this occasion I saw 

 more on the lower ridges at approximately 8,000 feet, than at the extreme 

 summit, and there is much easier footing. On the i8th, warm and sunny, 

 I found it fairly evenly distributed, though scarcely common, all over the 

 southern and eastern slopes of the mountain for about 7,500 feet up, but 

 confined my attention more to other species. But late in the afternoon I 

 took a female, in probably her first flight, within 200 feet of Lake Agnes, 

 that is, below 7,000 feet and within the timber line. I should mention 

 that this was during an abnormally late season. I believe, however, that 

 the summits may produce insect life earlier than the lower levels, as the 

 snow often goes from these first, and the rock-piles radiate the sun's heat 

 tremendously. In hot weather it is rather shy, but does not make very 

 long flights. With caution it is easily stalked. I have also taken this 

 species on Mt. Stephen, Field, July 7th, Mt. Field on the 8th, and saw one 

 settle close to me on the summit of a mountain about eight miles south- 

 east of Windermere, B. C. This was probably not above 7,000 feet, as 

 timber just reaches the summit. Specimens that I have seen in Pacific 

 Coast collections from Mt. Cheam are a little shorter in wing than the 

 Rocky Mountain form, in this respect resembling Bnicei. I am indebted 

 to Mr. Taylor for one of these specimens. 



46. This is Thecla iroides^ Bdv., according to Mr. Cook. I have 

 compared a short Calgary series with specimens labelled iroides^ from 

 Kaslo, Victoria, and Wellington, B. C, and they differ only slightly in 

 colour, the B. C. specimens inclining more to purple or violet beneath. 

 Some local specimens match them very closely, however. Dr. Dyar says : 

 "As between the two I should call your Calgary species aiigusttisV 

 Mr. Cook claims, in Can. Ent., XXXIX, p. 146, that the two are separable 

 by early stages. My dates are from May 12th to 29th. Mrs. NichoU 

 records it from Banff in May.
