Expands from 1-50 to 1-70 in. The male has the fore wings 
pale brown, with a greyish tinge, without any markings, except 
that in good specimens the disco-cellular nervule forms a fine dark 
line ; hind wings with a submarginal band slightly lighter than 
the rest of the wing. Female lighter brown, with a greyish brown 
hind-marginal border to all the wings ; fore wings with a faintly 
marked central wavy line or narrow band, the disco-cellular nervule 
showing more distinctly than in the male ; hind wings with a 
broad central band of smoky brown. Under side : Fore wings like 
those of CE. Norna, but of a duller brown, and entirely without 
black spots ; hind wings greyish white, with a broad central band 
of grey and brown, bounded on each edge by a distinct dark brown 
wavy margin ; base mottled with dark brown, and the hind margin 
suffused with the same colour throughout its whole length. 
Neuration brown in the typical form. PI. LXV., 3. 
Time of Appearance. — July. 
Habitat. — Dry sandy places in North Lapland ; it also occurs 
in Siberia and in Labrador, being circumpolar. 
Larva. — Pastor Sandberg has described a larva which he has 
taken in abundance on Festuca ovina, which grows on the sandbanks 
by the Jacob Biver, in the extreme north of the Scandinavian 
Peninsula, close to the Varanger Fiord, where the Norwegian and 
Russian territories join. In this northern locality the butterfly is 
extremely common. He did not succeed in rearing the larvae, 
some on account of their being unfortunately ichneumoned, others 
dying during hybernation. Sch<pyen * quotes his description of the 
larva as follows : — “ Clothed with fine hair, light yellowish brown, 
with darker lines along the body, namely, a narrow interrupted 
dorsal line, and a broader one along each side. Head small in 
proportion to the body, greyish yellow, with six slender dark longi- 
tudinal lines and black eyes. Body nearly spindle-shaped, white.
