264 LITHOCOLLETID &. 
Very common among oaksrin June. ‘The larva (according to 
Ratzeburg) mines in the autumn in oak-leaves, making large 
white blotches, within which the larva may be observed in a 
curved position; the mined leaves remain perfectly flat. The 
larva, when full-fed, spins its cocoon within the leaf, but remains 
unchanged till spring; there does not appear to be more than 
one brood in the year. (I have repeatedly met with the larvae, 
but have not hitherto succeeded in rearing them.) .

Head fuscous, mixed with yellowish. Face and palpi yellowish. An- 
tenn fuscous. Anterior wings bright yellowish, with the costa nar- 
rowly fuscous at the base, more broadly towards the apex, the hinder 
margin Jroadly fuscous, with a round black spot above the anal angle ; 
cilia at the apex ochreous, at the anal angle grey. Posterior wings fus- 
cous, with paler cilia. 
Jommon among brambles in May and August. The larva 
mines the leaves of the bramble in autumn and winter, and in 
July ; the mines appear as whitish blotches, palest at their origin, 
of a cornucopia shape; they pucker the leaf a little; the larva 
changes to a pupa in the mine, not forming a cocoon; the pupa 
is extremely active.
