THE CANADIAN ENTOMOLOGIST. 191 



few, mostly worn, whilst on a visit to the same locality on July 23rd of last 

 year. I observed none south of the river. In habits and flight it is 

 peculiarly like Chionobas Alberta, and, indeed, it is not altogether unlike 

 that species in habitus. 



577. Satyrus sylvestris, Edw., var, charofi, Edvv. — This seems pecul- 

 iarly erratic in its distribution. I never met with it until 1904, when I took 

 three males, quite fresh, on, and in coulees near, the Red Deer River flat 

 north-east of Gleichen, on July glh. I found it on both sides of the river, 

 but saw no others. It was evidently just appearing. Mr. Hudson and 

 I failed to find it there in early July of the following year, nor did I see 

 any when there between July 23rd and 27th of last year. It occurs at 

 Banff, as Mrs. Nicholl took it there in 1904, and I saw one in the museum 

 labelled by jNIr. Sanson, "Sun Dance Canyon, July i8th, 1906." Mrs. Nicholl 

 tells me she found it jiist coming out on Kootenai Plains in mid-July of 

 last year, and I found it, rather sparingly (as I did any other butterflies), 

 at and below Windermere, on the Upper Columbia, B. C, from July loth 

 to 14th. It appears to be a mountain species, but as it occurs on the Red 

 Deer, I cannot understand why, during 14 years' collecting, I should have 

 had no records from within sixty miles of Calgary. Geddes records it 

 from "Garnet Ranch" (Pincher Creek), and I have a specimen taken by 

 a non-entomological friend at Mt. Head, in 1906. Sylvestris, by the way, 

 is really the variety. Holland says : " The form wnth obsolescent ocelli 

 has been named sylvestris by Edwards." Edwards, however, in Butt. N. 

 Am., Ill, says : " It is charon, bandless on under hind wing ; and this 

 variation is not uncommon wherever the species is found." I have this 

 variety from the Upper Columbia. 



578. CJiionobas Brucei, Edw. — Mr. Edwards in his Volume III says: 

 " Mr. Bean reports finding Brucei at Liggan, Alberta." This is probably 

 an error, as in part of the same work, published. several months later, he 

 quotes from Mr. Bean : " . . . On a mountain near Hector, B. C, 

 two miles west of the Alberta Province line, . . . lives Chionobas 

 Brucei, never yet observed at Laggan, only nine miles distant." Mrs. 

 Nicholl kept a sharp lookout for it during her five or six weeks' collecting 

 in those regions during 1904, but failed to come across it. But she found 

 it in considerable numbers far to the north of Laggan during the latter half 

 of July, 1907. She writes: "I have taken Brucei in plenty. It is 

 evidently a more northern species than Beanii, and I think harder to 

 catch. . . . The first place I took it was on a mountain at the head
