Caput superne et in fronte Ti ies Ocelli nulli, Antenne & seta- 
cew, ciliate. Os pilosum, palpis sudnullis, Ale oblong, medio- 
criter ciliates; anteriores: cellula discoidalis venas guingue in mar- 
ginem posticum emittit simplices. 9 dptera, ano lanato. Larva 
saccophora, sacco breviusculo, granulato, anum versus attenuato. 
Head above and in front hairy, Ocelli none. Antenne of the g 
setaceous, ciliated. Maxillary palpi undeveloped. Labial palpi ea- 
tremely short, almost concealed in the hairs of the mouth. Wings ob- 
long, with moderate cilia. From the discoidal cell of the anterior 
wings jive simple veins run to the hinder margin. 9 Apterous, with 
the anus woolly. Larva case-bearing ; the case rather short, granulated, 
attenuated towards the anus. 
The food of the larve is probably lichen; the cases are found 
on the trunks of trees, palings, and rocks ; “the larvae being full 
fed in the early spring. 
The only two British species, of which we know the males, are 
very closely allied. We appear to have several species of larvee, 
but from some only females have yet been obtained, from which, 
without continued observations of the larvee, cases, and whole 
habits of the insects, it is impossible to distinguish the species. 
It is in this genus that we meet with the singular physiological 
fact of unimpregnated females laying fertile eggs, and not as the 
exception, but as the rule. (See Trans. Ent. Soc. London, vol. i.

1. inconspicuella, Sta. Cat. p. 6 (1849); Zell. Alis anticis an- 
gustulis, apice rotundato, cinereo-fuscis, maculis numerosis irregularibus 
mediocribus albidis via distinctis, margine postico fusco-punctato. Exp. 
al. 53-6 lin. 
Head and face grey. Antenne dark-grey. Anterior wings rather 
narrow, with the apex rounded, greyish-fuscous, with numerous irregu- 
lar rather large whitish spots, xo¢ sharply defined ; on the hinder mar- 
gin is a row of dark spots; cilia alternately whitish and greyish-fuscous. 
Posterior wings pale-grey, with paler cilia. 
Not common. The larvee are full fed before the end of March, 
when they may be found on palings; the perfect insect appears 
early in April. 
2. Douglasii, n. sp. Alis anticis wiv angustis, apice paullulum 
rotundato, cinereo-fuscis, apicem versus saturatioribus, maculis numerosis 
irregularibus mediocribus fere distinctis albidis. Exp, al. 6 lin. 
Head, face, and antenne greyish-fuscous. Anterior wings hardly 
narrow, with the apex slightly rounded, greyish-fuscous, towards the
