cous, the basal joint with a long ochreous tuft. Anterior wings white, 
with the veins broadly yellowish, towards the apex inclining to brown ; 
costal cilia brown, at the tips white; hinder marginal cilia pale fuscous. 
Posterior wings fuscous, with paler cilia. 
Appears in June and July, but nowhere common. ‘The larva, 
which feeds on oak, is full-fed in May; the case is somewhat like 
that of anatipennella, but has several little projections on the ° 
back ; it has been found at Epping and Wimbledon Common.

Head and face pale ochreous. Palpi whitish. Antenne while, the 
basal joint thickened, with no tuft, ochreous. Anterior wings ochreous,

Head greyish-ochreous. Face and palpi whitish. Antenne white, 
annulated with fuscous, the basal joint grey, slightly thickened, with a 
few projecting scales beneath, but hardly sufficient to be considered a 
tuft. Anterior wings ochreous, darker towards the costa, with the costa 
nearly to the apex white, and with a very slender white streak along the 
Sold and the inner margin narrowly white ; cilia greyish-ochreous. Pos- 
terior wings grey, with paler cilia. 
The perfect insect is occasionally met with in June and July, 
and has occurred in various localities, but is nowhere abundant. 
Mr. Shield, who discovered the larva of this species, finds the 
cases abundantly on Lotus corniculatus, near Dublin, in May. 
The young larvee begin feeding in autumn; the brown case is 
rather curved, almost hooked at the end, and has a flounced ap- 
pearance ; the mined leaves appear very white.
