NORTH-COUNTRY SPECIES AND FORMS OF LEPIDOPTERA. 87 



croak resounding finely as it echoed among the crags " in sym- 

 phony austere." ■' But epiphron ceased long before I got to the 

 top. I saw nothing of it about Sprinkling Tarn, and only one 

 worn specimen rewarded my search round Sty Head Tarn. 

 I was surprised at my failure, so nearly complete, to find it, as 

 it was seen, according to Newman, " in considerable abundance" 

 at both these places a generation or two ago.f Since my return, 

 however, I have learnt that Dr. A. H. Foster has also failed to 

 find it at these old localities in his exploration of the distribution 

 of epiphron in the Lake Country.! He does not give Angle Tarn 

 as a locality, but finds it along the high ground separating the 

 head of Borrowdale from the Buttermere and Eunerdale valleys 

 as well as on the Langdale plateau, Helvellyn, and the Red 

 Screes. If it has been exterminated about Sty Head and 

 Sprinkling Tarns the need of moderation in collecting would be 

 evident, but we found it so abundantly that I have not hesitated 

 to make public the results of our experience. 



The butterfly fauna of Langdale appears very limited. 

 P. icarus, one specimen of a " white," A. urticce, E. epiphron and 

 C. pampJiilus made up our list. 



Loch Eannoch was the locality which we had selected as our 

 hunting-ground for the Scottish forms, and we have no reason to 

 regret our choice. 



We reached Pitlochry on the evening of July 3rd, and about 

 9.30 next morning set off for the twenty miles' drive to Kinloch 

 Eannoch. Stnian, some distance further along the line, gives 

 an easier means of access, but the drive up the Tummel Valley 

 from Pitlochry is through incomparably finer scenery. We 

 found very comfortable quarters with Miss Maclntyre at " Eiver 

 View." Kinloch-Eannoch is not (as the name would imply) at 

 the head, but at the foot, of Loch Eannoch, where the river 

 Tummel, the haunt of oyster-catchers and black-headed gulls, 

 flows out in its easterly course to join the Tay. Loch Eannoch 

 is nearly ten miles long and a mile wide for most of its length 

 and lies in a fine open valley, with big mountains guarding its 

 eastern end — Beinn a Chuallaich (2925 ft.) to the north and 



* The whole of this verse so finely draws the environment of epiphron in the 

 Lake country that I hope I may be permitted to quote it : 

 " There sometimes doth a leaping fish 

 Send through the tarn a lonely cheer ; 

 The crags repeat the raven's croak, 

 In symphony austere ; 

 Thither the rainbow comes — the cloud — 

 And mists that spread the flying shroud 

 And sunbeams ; and the sounding blast, 

 That, if it could, would hurry past ; 

 But that enormous barrier holds it fast."
