THE CANADIAN ENTOMOLOGIST. 15 



very summit of Mt. St, Piran, so we made the ascent of that peak. When 

 we arrived at the rocky top, the tem.perature was below freezing and snow 

 was falHng and the wind blowing a fearful gale. Dr. Fletcher captured a 

 specimen of Ckionobas Beanii at a time when the sun shone through a 

 break in the clouds. A butterfly came toward me as though it had started 

 from the South Pole, and when I raised my net to make a stroke it turned 

 and made for the North Pole, and, as far as I know, never stopped until 

 it reached there. I feel sure it was aztarte. The weather continued bad 

 during our brief stay in the mountains, and we did not get this interesting 

 species. It is said in a general way that the species is found about the 

 tops of the Rocky Mountains of Canada, and this article is a contribution 

 towards our knowledge of its habitat. It is quite interesting, and perhaps 

 important, to know the exact places where species are found. Mr. Bean 

 says it occurs on a mountain, three miles south-west of Laggan, 8,500 ft. 

 altitude, and on a low smooth mountain directly north of Laggan. He 

 also says it occurred at Lake Agnes in 1892. 



Mrs. Nicholl says : '" Everywhere Brenthis astarte was to be seen, 

 though not generally to be caught, on every peak over 8,000 ft." The 

 males haunt the summits, and the females are to be found on the highest 

 grassy slopes. Mrs. Nicholl records it from Glacier Crest, Selkirk 

 Mountains. Mrs. Chas. Schseffer recently presented two specimens to the 

 Academy of Natural Sciences of Philadelphia, which were taken on Mt. 

 Athabasca (7,200 ft. alt.?). She says it has also been taken on Mt. 

 Temple, above the saddle. Mr. AVolley Dod records it from Devil's Lake 5 

 near Banff Mr. N. Sanson captured a specimen on Sulphur Mountain at 

 Banff From the above record's, where should a collector go to get the 

 species ? It is no joke to climb these mountains, and one cannot step 

 from the top of one to the top of another on the basis that they are flying 

 around nearly all the peaks over 8,000 ft. altitude. Some of the localities 

 mentioned are exact and some are not. It would be far better to give the 

 names of the peaks where any butterfly is found, and if possible the 

 altitude of the place of capture. Mr. Bean gives a very interesting 

 account of the altitudes where he worked, but does not name the peaks. 

 Perhaps they were not named when he was at Laggan.* I wish to pay 

 tribute to the valuable work done by Mr. Bean in making known the 

 butterfly fauna of this region. 



*This was actually the case with most of the mountains at Laggan in 1890, 

 when Mr. Bean rediscovered A. astarte. — [Ed. C. E.
