LEPIDOPTERA OF JEMTLAND AND LAPLAND. 359 



let, born at the tail of a perennial snowdrift, in its progress 

 towards the bottom has lost itself and thereby caused some 

 boggy place. Here are to be found, often in abundance, the 

 plants that are necessary to the existence of the Lepidoptera, 

 and here, with few exceptions, we may expect to see the special 

 butterflies that are the object of our search. They are not 

 usually very abundant, for, with the exception of a few species, 

 we may collect hard all day and get perhaps a dozen examples 

 of what we want ; but these will repay, by their beauty, their 

 rarity, and their interest, the trouble taken in procuring them. 



I left England on the evening of May 31st last, and travelling 

 overland, via Sassnitz and Trelleborg, reached Stockholm on 

 that of June 2nd. Here, amongst other events, I visited the 

 Natural History Museum, and called upon the veteran Scandi- 

 navian lepidopterist. Professor Aurivillius, who received me most 

 kindly, and courteously showed me the national collection of 

 Swedish Lepidoptera. 



Leaving Stockholm on the evening of June 3rd, I arrived at 

 Mattmar, at the north-west corner of Lade Storsjo, in Jemtland, 

 about noon the next day. The attraction for me at Mattmar 

 was the very fine bog which exists there, and which is now un- 

 fortunately, from the lepidopterist's point of view, being drained. 

 This swamp is covered with a growth of crowberry, cotton-grass, 

 bog-bean, cloud-berry, lichens, moss, and dwarf birch and 

 sallow, amongst which various charming flowers, including 

 Andromeda polifolia, is abundant. Here and there in the 

 drier parts straggling larches and pines maintain a precarious 

 existence, the rising ground around the swamp being thickly 

 covered with spruce and pine, with groves of birches in places. 



I found at Mattmar a small hotel or inn, very clean and 

 inexpensive, and the good people most obliging and anxious to 

 do their best. After partaking of lunch and unpacking, I made 

 for the swamp under the guidance of a friendly native, who spoke 

 a little English, and who had, with the kindliness and courtesy 

 which I found everywhere in Sweden, offered to pilot me round. 

 The day was sunny, and although it was late in the afternoon, 

 I soon obtained examples of Brenthisfreija, B. frigga, B. aphirape 

 var. ossianus, Chrysophanus amphidamas var. obscura, which was 

 abundant, and Brenthis euphrosyne. 



The next day I annexed, in addition to further examples of 

 the foregoing, specimens of Erehia embla and Q^neis jutta, one 

 only of each, unfortunately. 



June 6th was unfavourable, and collecting was not possible ; 

 the next day, however, there were bursts of sunshine, and I 

 obtained a fair number of specimens, including an example of 

 Hesperia centaurice ; but was my last success at Mattmar, for the 

 weather broke up entirely on June 8th, with,, snowstorms and 

 arctic temperature. On June 9th I left for Are, where there is
