Description

Similar to Euphydryas maturna. The forewing length is 17–23 mm. The wing upperside ground colour varies from brick-red to light yellowish-orange. The hind wing postdiscal band contains minute black dots. The hind wing underside outer margin is fulvous. altaica[replacement name E. intermedia altaiana (Wnukowsky, 1929)] bears a superficial resemblance to aurinia. The discal macular band, which is whitish yellow in the other forms, is here so much shaded with brown that it scarcely contrasts at all with the red-brown diffuse spots in the distal area of the wings. Beneath the entire costal and apical areas of the forewing are paler, only two black-edged cell-spots remaining deep red-brown; on the hindwing beneath the yellow marginal spots are larger and the black line dividing the yellow median band is partly vestigial, partly obsolete. From the Altai and the adjacent Central-Asiatic mountains. In wolfensbergeri Frey (65a), from the Alps (Albula, etc.), the basal area of the upperside is darkened by black markings on both wings, otherwise the prevailing colour of the upperside, and still more on the underside, is a very dark red-brown. ichnea Bdv. is a very brightly coloured intermedia in which the black dots in the reddish yellow submarginal band of the hindwing are especially prominent. In the very similar but more uniformly red-brown mongolica Stgr. …
