revision of the genus Argynnis. 549 



may be a form, but the markings of the under side 

 seem to me to show its nearer affinity with aphirape. 

 Alpheraky says that Kuldja specimens differ constantly 

 from those from Margilan, but the difference in my 

 specimens is very slight. 



A. stiene seems to vary less than most of the species, 

 but its aberrations are numerous, and some are named 

 and figured by Spangberg. The arctic var. liela in 

 typical specimens may be separated, but I think is hardly 

 deserving of a name. 



A. oscarus, as figured by Eversmann, is a sufficiently 

 distinct species, though my specimens are not so bright 

 in colour as his. He compares it with ossicmus, as 

 Fissen does with euplirosyne, but it seems to me nearer to 

 selene than to either, though it may be distinguished 

 from both by the larger size, and by the absence of any 

 silvery spots on the middle band of the hind wing below. 

 I have not seen enough of the variety australis to say 

 whether the difference is marked and constant, but 

 Graeser says it has the same relation to the type as 

 aphirape and euphrosyne have to ossianus and Jingal, and 

 that the difference is much greater. 



A.perryi, Butl., from Possiet Bay, of which I have seen 

 the typical specimens, appears to be the same as 

 iphigeneia, but the identification is not certain. 



A. iphigeneia is a species of which I know but little. 

 I have a single not very fresh specimen from Amurland 

 which agrees with Graeser's specimens and description 

 exactly, and three others from Gensan in Korea, collected 

 by Mr. Leech, which agree with it in the shape of the 

 wings, but on the under side show more of the markings 

 of selene. Graeser sa3's it is near oscarus and euphrosyne, 

 but differs from both in the longer narrower wings, and 

 in the colour and pattern of the under side of the hind 

 wing. I cannot consider it as a variety of either of 

 these species, and, without seeing a long series of both 

 sexes, am not able to say that it is distinct, though 

 before Graeser had described it, I had separated my 

 specimen as one which I could not identify with 

 certainty. 



A. euphrosyne, var. fmgal, is a boreal form which in 

 Lapland, Jemtland, Finland, and other parts of Northern 

 Europe, and perhaps Asia, appears pretty constant ; but 

 the form found at Bodo in Arctic Norway is eupJcrosyne,
