''E. embla'' Thunb. (= ''dioxippe'' Hbn.) (37 h). Dark grey- brown above, the hindwing being feebly dentate and the fringes chequered brown and grey. The forewing bears 3 black eye-spots in brown yellow rings, the anterior one being largest and having mostly 2 white pupils, while the 2 posterior ones are shifted distad and are small, black, and without pupils. There are on the hindwing mostly 3—4 black ocelli which are bordered with brown -yellow, have no pupils and are sometimes absent. The forewing beneath somewhat darker than above, the apex and part of the distal margin being dusted with ashy grey The ocelli are not brown -yellow, but light with ochre -yellow ring, these more prominent than above. The hindwing beneath densely dusted with white-grey, bearing a more or less prominent, brown, distally somewhat dentate, median band, at the outside of which there is sometimes a larger, somewhat diffuse, grey costal spot and usually a small white central one. Before the distal margin there are some black dots, which are here and there narrowly edged with yellow. In Scandinavia , North Russia and Siberia. — ab.
