Perthshire district, said, as quoted by Mr. E. Newman in the 

 Zoologist, 1841: "They appeared confined to a spot of level 

 and rather marshy ground, about one hundred and fifty yards 

 in length, and fifty yards in breadth ; it was grassy, but 

 witliout heath, and although there was plenty of heath all 

 round the neighbourhood, I did not see a single specimen 

 settle on it. The locality is among rocky mountains, some of 

 which attain an altitude of four thousand feet above the sea 

 level, and I think that one locality where I found the butter- 

 fly, is at least three thousand feet above it." 



The butterfly has since been found in many other localities 

 in Scotland — on one of the hills near Ben Nevis; in the greatest 

 profusion in 1866 on Ben Nevis itself; on all the mountains 

 round Loch Rannoch, which are of a sufficient elevation ; near 

 Loch Vennachar ; and in the Tay district and Argyleshire. 



In England it is found, at similar elevations, in many parts 

 of the lake district of Cumberland and Westmoreland, as on 

 Helvellyn, where it was found in 1859, in plenty about three 

 fourths up the mountain, in patches of boggy ground : at 

 Stye Head Tarn and at Green Cragg, Borrowdale ; on Green 

 Gable Mountain at the head of Buttermere, and at Langdale 

 Pikes. 



Red Skees, Ambleside, is another favourite locality, in 

 grassy places abounding in springs, on the mountain sides, 

 where it was taken as early as 1809, by Mr. Stothard, and a 

 few years later by Messrs. J. Curtis and J. C. Dale. No locality, 

 south of the Lake district is known in England, and there is 

 even no record from the mountains of Wales ; but in Ireland 

 it was taken in some numbers in 1854, by Mr. E. Birchall, 

 on Croagli Patrick IMountain, Mayo, in a grassy hollow, aljout 

 half way up the mountain side above Westport. 



Abroad, it is widely distributed in the Alps, the Pyrenees, 

 the Vosges, and the mountains of Hungary and of Piedmont, 

 always at a considerable elevation ; also (the form with white 

 pupils to the black dots) on elevated slopes and in mountain 

 meadows in Germany, Silesia, Switzerland, and the Rhine
