very narrow streak on the fold, and the inner margin narrowly white ; 
cilia at the apex dark fuscous, below paler. Posterior wings pale grey, 
with paler cilia. 
Occasionally met with amongst broom in July.

Head, face, and palpi whitish. Antenne white, spotted with fuscous 
beneath, the basal joint slightly thickened, with a few projecting grey- 
ish scales beneath. Anterior wings white, with slender ochreous veins ; 
cilia greyish. Posterior wings grey, with greyish-fuscous cilia. 
Common among Lehium vulgare in July. The larva feeds on 
that plant from autumn to June, in cases formed of pieces of the 
| mined leaves ; these cases are very broad, almost triangular, dirty 
grey, and from the prominent stiff hairs of the leaves have a sin- 
gular appearance; the young larvee, in autumn, mine sufficient 
for the construction of the case, but do not detach it from the 
leaf till the spring, it consequently only appears as a portion of 
withered leaf. The larva was first observed by Brahm on Onosma 
echioides ; it feeds also on Anchusa.

Sta. Alis anticis angustulis albis, venis dilatatis ochreis, postice con- 
x Jluentibus, costa anguste alba; antennis albidis fuscescente-annulatis, 
articulo basali incrassato, non penicillato. Exp. al. 7 lin. 
Head, face, and palpi pale ochreous. Antenne whitish, annulated 
with pale fuscous, the basal joint slightly thickened, not tufted. An- 
terior wings narrow, white, unspotted, with the veins rather broadly 
ochreous, posteriorly confluent ; the costa is narrowly white to near 
the apex; cilia ochreous. Posterior wings grey, with paler cilia. 
Appears in June and July in grassy places, but hitherto very 
scarce; I only know of two specimens which I can unhesitatingly 
refer to this species, of which one is in Mr. Wilkinson’s collec- 
tion, and the other in my own.
