The lepidoptera of the Orisons — Preda and The Albula. 



By J. W. TUTT, F.E.S. 

 The morning of August 18th, 1907, broke cloudless, but there was 

 a nip in the air which was in consonance with the snow that was lying 

 low on all the mountains around. The last week of broken weather had 

 been spent in the land of the butterfly " tripper," but here, one was 

 on classic ground. Long had we hoped to see the country between 

 Bergiin and the summit of the Albula. For years, ever since we had 

 begun to study the " plumes," the names of the favourite corners 

 between Bergiin and the Albula summit, that Zeller so dearly loved^ 

 "Preda," " the Weissenstein," and so on — had been familiar, for it 

 was here that much of our present knowledge of " plumes " was 

 gained by the past-master of our craft when he spent the three 

 summers of 1871, 1873, and 1875 on this excellent collecting ground, 

 and here was I at Preda. But I felt an outsider, remaining here only 

 for a day or two, and dependent on the weather of those days to see 

 the country that Zeller hunted so long and so closely. However, the 

 Fates were so far kind that I got two splendid days here, for, on the 

 19th, the ground of the 18th was more carefully covered, and, before 

 I had unfurled my net, many interesting species were seen on the 

 rough slopes outside the inn and railway. Slowly and carefully 

 working upwards, I was much struck with the excellent appearance of the 

 country for lepidoptera, not so much for butterflies, but rather in the 

 "down" nature of many of the slopes and flats, covered with short 

 grass and an abundance of flowers, that reminded one much of our 

 Kentish downs, for, as a rule, the Alps are not strong in Microlepidop- 

 tera, but here were possibilities of which we knew Zeller had long 

 since had complete knowledge, and of which he had taken full advan- 

 tage. But these are the notes of a " tripper," and anything fuller 

 that may have been obtained will appear in due course, in connection 

 with our more comprehensive account of the butterfly species noted. 

 Directlyoutside the inn, Brenthis inoiind B. amathima were as abundant 

 as Anjijnnis iKjlaia and A. niobe, but the limit of the two first-named 

 species appeared to be not much more than 500ft. elevation above Preda, 

 i.e., the region of the trees above the inn. About this low^er ground,
