revision of the (jenus Argynnis, 555 



in the Alps, where it occurs at 3 — 6000 ft., and, as far 

 as I have seen, in shaded valleys on the edge of pine 

 and larch woods, where it settles on the flowers of the 

 rhododendron. In Jemtland, and on the Dovrefeild, a 

 form occurs which is intermediate between the dark 

 aljDine and the pale Lapland and eastern variety horealis. 



A. amphilochus is a very distinct species, which seems 

 to have no near allies in Europe or Asia, and is, as far 

 as yet known, confined to a limited district near the 

 watershed of the Upper Amur. 



A. astarte is an almost unknown species, which was 

 discovered in some part of British Columbia (perhaps on 

 the Cascade Mountains) many years ago, by some of 

 Lord Derby's collectors. The type is in the British 

 Museum, and seems to have been overlooked both in 

 Strecker's and Edwards' catalogues, probably because 

 the locality is incorrectly given in Kirby's catalogue as 

 Jamaica. It has never been since found by au}^ entomolo- 

 gist, and seems to me a species quite distinct from any 

 other in North America, and most nearly allied to 

 am2yhilochus. 



A. ino varies little except in size, and I should 

 not have said that the var. amurensis is a well-marked 

 form ; but as both Staudinger and Graeser, who have 

 seen it in hundreds, say that independently of its 

 usually, but not always much greater size, it can be 

 recognised by the different colour of the under side of 

 the hind wing, I retain the varietal name against my 

 own opinion, which is based on the examination of a 

 much smaller number of specimens. Excepting by 

 de I'Orza, itio has not been recorded from Japan, but 

 there are three specimens in Mr. Godman's collection, 

 taken by Jonas at 5000 ft., which are certainly nothing 

 else ; and Mr. Leech has also three specimens from 

 Oiwake, Japan, taken by Pryer. 



A. dajjhne is another species of very wide range, which 

 does not vary much except in its extreme eastern range, 

 and there in very much the same way as the last. I am 

 not at all sure that the Japanese and Amur form can be 

 constantly recognised, as I have not a long series of 

 either, but those I have from Japan, Amurland, and 

 Korea, all agree in being somewhat larger, the outer 

 margin of the fore wing a trifle less rounded, and the 

 under side of the hind wing somewhat greyer and less 

 violet than the average of European specimens.
