times wet weather that we had experienced in the south. Boasekop 

 is classic ground for the Naturalist and Entomologist, aud has been 

 well examined, though it is uot much known to the British Lepido- 

 pterii-:t, except through Dr. Staudinger's visit there in 1860 {cf. 

 Entomologists' Annual, 1861, pp. 4 — 27). We learned at Bossekop 

 that some German Entomologists had paid it a visit some few years 

 ago, but could hear of no visits by English Entomologists. We met 

 no one who remembered either Mr. Walker's or Dr. Staudinger's visits. 



We found satisfactory quarters at the Inn, for Bossekop possesses 

 an Inn, aud met there with a party of Swedish botanists, who success- 

 fully verified the habitats of certain plants occurring nowhere else in 

 Europe, though met with also in Labrador. 



Our first hunt was after Erehia Disa ; we duly found it, but it 

 was practically over, the few found were worn to rags, and were 

 largely females that had laid all their eggs. The middle of June 

 would probably be none too soon to find it in good order. We found 

 it over a large area, in fact wherever the moltibar (Hubus chamcemorus) 

 bog occurred amongst the pine trees : where the pine wood was drier, 

 or on treeless bogs, it did not occur. However, our experience was so 

 small and belated a one, that our observations may easily prove to be 

 defective. It was in very similar localities to those in which Emhla 

 occurred at Saeterstoen, reading pine for fir, there being only pine and 

 no fir in any part of the Alten district we visited ; on the wing it was 

 very similar in appearance. 



A butterfly which had not been out very long on our arrival, and 

 which we found to be still in fair condition, was Erehia i?oIaris, a 

 local form of E. Medusa. It would be difiicult to say where this 

 species did not occur, odd specimens appearing in the most unlikely 

 places, but it was certainly most frequent in some of the enclosed 

 meadows not far from the sea, where the grass was put up for hay, or, 

 if pasture, not eaten too closely. It presented considerable variety in 

 the extent of the development of the eye-spots, some specimens 

 approaching typical Medusa, others being nearly free from markings. 



Erehia Jafpona also occurred, but only in single specimens at 

 considerable intervals of time and place. 



Erehia Ligea was not met with at Bossekop, but at Kaafiord (a 

 dozen miles oif) it put in an appearance about July 19th, a specimen 

 being brought us thence by one of the botanical party, and we took 

 it there on the 21st ; it was obviously common, but the weather pre- 

 cluded our seeing it for more than a limited number of minutes. I 

 may note here that we did not see it at Ilarstad on July 8th, where
