This colour predominates to such a degree as in other species is only the case in melanistic aberrations. Also the ground-colour of the underside is duller than in all the other Argynnis, the hindwing varying from dark brick-red to cinnamon-brown, only the median band being dark yellow. In the Alps, but at moderates heights in the forest region, not above 6000 ft. Also in the high North, Scandinavia and Finland. Northern specimens on the whole paler than alpine ones.[3]
