Lepidoptera of the Altai Mountains, 863 



those from Amdo in Grum-Grshimailo's collection, dis- 

 tinguishable by the greater development of the white 

 bands on the hind-wing below. 



162. G. hero, y&t. perseis, Lederer (c/. Staudinger, Iris, v, 

 p. 338. Herz, op. cit. xi, 248). 



I found this in the Tchuja Valley from 3000—4000 feet, 

 fresh in the middle of June, and in the Upper Bashkaus 

 Valley on July 24th. On the average they differ from 

 the ordinary European form which extends to the 

 Ural in having rather more developed white bands 

 below, and the ocelli more distinct above. The same 

 characters are even more pronounced in specimens from 

 the Amur and Askold, so that perhaps the name oiperseis 

 may be applied generally to Asiatic races of this species, 



163. C. tiphon, Rott. var. 



I found this species in some of the more marshy parts 

 of the valleys at about 5000—7000 feet. They belong 

 to a form which differs a little from Alpine and North 

 European specimens, of which I have a large series. 

 They come nearest on the upperside to some of those 

 taken in Colorado which are known as ochracea and 

 inornafa, W. H. Edw., but are more spotted on the 

 underside. They are slightly larger and darker in colour 

 than those known as ca^ca, Stgr., from Turkestan ; they 

 are paler and about the same size as the average North 

 European forms known as isis, and quite unlike the pale 

 grey form known as vihiensis, M.en.,= g^'isescens, Christoph 

 (Iris, vi, p. 87), which Herz took on the Vilui river {cf. 

 Iris, xi, p. 249), and which I also have from the Verchojansk 

 district taken by Czekanowsky, and in a larger and 

 somewhat darker form from Kamtschatka as var. mixturata, 

 Alph. Having recently written on the variations of this 

 species in the Entomologist's Record, 1896, p. 228, 1 can only 

 add, that when a large series (my own includes something 

 like one hundred selected pairs from the Holarctic region) 

 are brought together it is practically impossible to define 

 exactly any of these varieties. 



164. ? C. pamphilus, L. 



This is recorded by Lederer as having been taken by 

 Kindermann, but I can find no Altai specimens in 

 Staudinger's collection.
