Description from Seitz
E. maurisius Esp. (36 e). The reddish brown band of the forewing is separated by the veins into a number of elongate spots — usually 6; the cell is more or less filled in with ferruginous brown, and behind the cross-vein there are 2 somewhat diffuse narrow streaks, which extend towards the distal band, in which they disappear. The hindwing has 6 round russet-yellow spots. On the underside the band of the forewing is lighter, and the space between the band and the darkened base is russet-brown; inner and distal margins blackish brown. The hindwing dark brown in the male, with very small, point-like, russet yellow spots. In the female the hindwing is grey-brown beneath, being finely dusted with greyish yellow, the ochre-yellow dots at the distal margin are prolonged to small stripes. In the cell there is a whitish yellow diffuse spot on the upperside. The fringes grey-brown in the male, whitish grey in the female. Antenna finely ringed, the club white on the inside, black-brown on the outside. Middle of July, on the Altai, from 2000 to 2700 m, on grassy slopes.
