other beyond the middie, the latter is connected with a short transverse 
black streak above the fold; on the costa beyond the middle is a dark 
fuscous blotch, followed by a slightly angulated, rather indented whitish 
fascia ; the hinder margin and apex of the costa are varied with whitish — 
and black scales; cilia pale fuscous. Posterior wings grey, with grey- 
ish-fuscous cilia. 
A scarce species; most of our specimens have been taken in 
the north of England, on the trunks of oaks in July and August.

Head and face pale greyish-fuscous. Palpi dark fuscous, internally 
whitish. Antenne fuscous. Anterior wings rather narrow, veddish- 
brown, suffused with fuscous, the inner margin paler, with two whitish 
spots above the fold, each preceded by a dark fuscous spot (the first 
not far from the base, the other in the middle of the wing); above the 
second is a black streak on the disc; towards the hinder margin is @ 
nearly straight, rather oblique, slightly interrupted, whitish fascia ; the 
hinder margin is dark fuscous; cilia greyish-ochreous, varied with fus- 
cous. Posterior wings pale grey, with greyish-ochreous cilia. 
Common on sandy coasts, amongst the short grass, from June 
to September,

rufo-ochreis, stria obliqua coste ante medium fusca, in plicam desinente,

Head and face greyish-ochreous. Palpi pale ochreous, beneath fus- 
cous. Antenni pale fuscous, with darker annulations. Anterior wings 
reddish-ochreous, with a short oblique fuscous streak from the costa be- 
fore the middle, not reaching beyond the fold; on the fold are three 
black spots, the space between the first and second is greater than that 
between the second and the third, which latter is in the middle of the 
wing; on the dise are three dark fuscous spots, the first a little beyond 
the second spot of the fold, the other two very near together beyond the 
middle; the pale angulated fascia is rather indistinct ; beyond it the api- 
cal portion of the wing is clouded with fuscous; the hinder margin and 
apex of the costa are spotted with dark fuscous; cilia greyish-ochre- 
ous, varied with fuscous. Posterior wings whitish-grey, with ochreous- 
grey cilia. 
Occurs on the coast in July and August; St. Osyth and Brigh- 
ton. Mr. Douglas bred this species last autumn from larvae he 
found at Brighton, in August, feeding on Salicornia herbacea and 
Chenopodium maritimum.
