LITHOCOLLETIS. 279 
veddish-orange (the extreme base paler), with three yellowish-silvery 
fasciee ; the first slightly curved, the second nearly straight, the third 
distinctly angulated, composed of two opposite spots, between the 
apices of which are some dark scales, all these are dark-margined to- 
wards the base of the wing, and their dark margins fade gradually into 
the ground-colour; beyond are two small silvery streaks on the costa 
and one at the anal angle; the dark apical streak is not collected into a 
regular form. Posterior wings grey, with paler cilia. 
Fitherto veryscarce in this country ; 1 once took a specimen near 
York, among alders in May. The larva (according to v. Nicelli) 
mines the underside of the leaves of alders.

Head dark reddish-brown. Tace and palpi white. Antenne dark 
brown, the tip whitish. Anterior wings narrow, dark reddish-brown 
(the extreme base paler), with two slightly curved fascize, three costal 
and two dorsal streaks silvery, yet rather of a yellowish tinge; all these 
markings are dark-margined on the side towards the base; the first 
costal streak is rather anterior to the first dorsal streak, hence they 
have not so much the appearance of an angulated fascia as in Lrdli- 
chiella ; the apical black streak is oval and more collected into a regular 
Jorm than in Lrélichiella. Posterior wings grey, with paler cilia. 
Appears in May and August ; occurring in the vicinity of oaks 
and nut-bushes. 
34. INicellii (Zell.), Sta. Zool. 1851, App. clxxii.—déristigella, v.

introrsum fusco-marginatis, striola apicis elongato-ovato atro. Exp. al.

“Head bright saffron. Face and palpi white. Antenne whitish, an- 
nulated with fuscous nearly to the tip. Anterior wings shining saffron, 
with two slightly curved and one angulated silvery-whitish fascia, in- 
ternally narrowly margined with dark fuscous; before the apex are 
some black scales forming nearly an elongate-oval streak, above them 
are two short silvery-whitish streaks from the costa, and beneath is a 
smaller one from the anal angle. Posterior wings grey, with greyish- 
ochreous cilia. 
Hitherto scarce; appears in May and August. The larva mines 
the underside of the leaves of the nut in autumn and July. The 
larvae have been found by Mr. Wilkinson near Hackney, and the 
perfect insect bred by him.
