Description from Seitz

varia Meyer-Dür (65b) is a smaller form from the higher Alps, recognizable by the markings on the hindwing beneath, which are pale yellow in the nymotypical form, being silvery white. In the male the markings in the median area of the forewing are usually somewhat obsolescent, the network formed by the veins and transverse lines being interrupted or paler before the apex. The female often shaded with blackish, the ground-colour having a tint of brass-colour or olive; the abdomen very heavy.[1]
