202 GRACILARIID®, 
of moderate length, naked. Maxillary palpi rather long, filiform, La- 
bial palpi slender, ascending, the second joint beneath with a tuft of hairs, 
the terminal joint slender, pointed. Wings with long cilia, the anterior 
elongate, the posterior lanceolate. In the anterior wings the subcostal 
vein is interrupted towards the base; the discoidal cell is obtuse, and 
emits nine veins posteriorly (in C. Brongniardellum the discoidal cell is 
acute, and emits eight veins posteriorly) ; the subdorsal vein is simple ; 
in the posterior wings the apical vein terminates above the apex, below 
it is a fureate vein; the median vein is trifid. 
The species of this genus, three in number, resemble the G'ra- 
cilaria in habits. ‘The larvee mine or roll up leaves. 
The genus may be thus subdivided :— 
‘a. With a hook in the cilia of the anterior wings. Species 1. 
aa. With no hook in the cilia of the anterior wings. Species 2, 3.

Head greyish-brown. ace grey. Palpi whitish; terminal joint 
fuscous. Antenne dark fuscous, annulated with whitish. Anterior 
wings greyish-brown, with four oblique whitish streaks from the costa, 
margined towards the base with dark fuscous; the first not far from 
the base of the wing meets a short whitish streak from the inner mar- 
gin, forming with it an angulated fascia; on the middle of the inner 
margin is another short whitish streak, dark-margined towards its apex ; 
at the anal angle are a few whitish scales, followed by some fuscous 
scales; cilia of the hinder margin whitish, with a dark line externally, 
and a black hook from the apex; cilia of the inner margin grey. Pos- 
terior wings fuscous, with grey cilia. 
Not uncommon in many places among oaks, in April, June, 
August, and September. The larva feeds in May and the begin- 
ning of August; it mines the leaves of the oak (according to 
Réaumur), mining when young, several in one leaf, in galleries, 
afterwards forming a common blotch of considerable size.
