Head, face, and palpi grey. Antenne dark fuscous. Anterior wings 
grey, mottled with darker, with a black blotch on the inner margin, 
from near the base to beyond the middle, indented or interrupted in 
the middle and not reaching to the fold; a small spot at the anal angle 
and a streak at the apex of the wing black; cilia pale grey, opposite 
the apical streak dark grey. Posterior wings pale grey, paler towards 
the base, with paler cilia. In the variety maurelius, Step., the entire 
dorsal half of the anterior wings is blackish, only a narrow space along 
the costa being greyish-ochreous. 
Sometimes not uncommon among elms in July and August. 
The larva feeds in May on elm, beech, and (according to Madame 
Lienig) honeysuckle.

A most variable species. Wead, face, and palpi greyish-ochreous or 
fuscous. Antennee pale or dark fuscous. Anterior wings either grey- 
ish-ochreous, pale ochreous, reddish-ochreous, or fuscous, with a dark 
fuscous spot above the fold beyond the middle; sometimes with a thick 
dark fuscous streak along the middle of the wing, sometimes with nu- 
merous pale streaks upon a dark ground ; cilia usually paler than the 
wing, frequently with the apex dark. Posterior wings grey, with paler 
cilia. 
Abundant among oaks in August and September ; hybernated 
specimens are not unfrequent in the spring. The larva, which 
(according to Madame Lienig) is almost as variable as the perfect 
insect, feeds on oaks in May.
