From Russia throughout Anterior Asia to West China, Tibet and the Tian-shan.

— The form nigricans form, nov., from Juldus, of which I have a female, has the upperside of the wings black; the median band of the fore-wing consists of only two spots, the lunule at the apex of the cell is absent, so that the disc bears only three white dots and a diffuse smear in interspace 2.

The underside of both wings almost normal, but the centre of the forewing is nearly black, the white spots of the hindwing on the contrary broader and all very sharply developed.

nomas Lederer, 1855] (85 f) resembles name-typical specimens above; the underside of the hindwing, however, is uniformly white, without markings.
