PERITTIA, 177 
Head smooth. Forehead broad. Ocelli none. Antenne rather 
thick, filiform (viewed through a lens, pubescent), the basal joint short. 
Tongue very short, barely perceptible. Maxillary palpi filiform, con- 
nivent. Labial palpi short, drooping, filiform, the third joint distinct, 
pointed. Wings with long cilia, the anterior rather broad, appearing 
considerably broader from the cilia, the inner margin bearing a project- 
ing tooth of scales, the posterior ovate-lanceolate. In the anterior wings 
the discoidal cell is obtuse; there is no secondary cell; the apical vein 
is forked; below it are five remote veins; the submedian is hardly 
thickened ; the subdorsal has a long fork. In the posterior wings the 
costal cell is narrow and elongate, the apical vein is simple, below it 
are fwo separate veins; the two last branches of the discoidal cell are 
not united in a fork. 
Only a single species is known in this genus, and little is known 
of its habits; the larva is entirely unknown.

dentella, Sta.—atrella, Step. Alis anticis saturate fuscis, albido-irro-

saturate fusca. Exp. al. 44 lin. 
Head and face dark fuscous. Palpi grey. Antenne: fuscous. An- 
terior wings dark fuscous, irrorated with whitish scales, with two indis- 
tinct pale spots on the inner margin, one a little before the middle, the 
other at the anal angle; in the middle of the inner margin is a pro- 
jecting tooth of dark fuscous scales; cilia dark fuscous. Posterior 
wings dark grey, with paler cilia. 
Not common; occurs at Sanderstead, in May. I met with it 
near Chudleigh, in June, flying from a hawthorn hedge. 
Genus V. PERITTTIA, x. g. 
Capilli depressi. Ocelli nulli. Antennee fenwes, mediocres. Haustellum 
mediocre, squamatum. Palpi labiales mediocres, denues, filiformes, 
acuti, penduli. Ale longe ciliate, anteriores elongatie, posteriores 
lanceolatee ; anteriores: cellula discoidalis acuta, ex angulo suo api- 
cali furcam in ale apicem emittens, in costam venas duas, in mar- 
ginem posticum venas tres; cellula secundaria nulla; submediana 
breviter incrassata; subdorsalis simplex; posteriores: cellula cos- 
talis perangusta pone medium desinens ; venze subdorsalis et mediana 
Jurcate, inter eas vena unica e venula transversa procedit. 
Head smooth. Ocelli none. Antenne s/ender, moderately long. 
Tongue of moderate length, clothed with scales. Labial palpi mode- 
rately long, slender, filiform, pointed, drooping. Wings with long cilia, 
the anterior elongate, the posterior lanceolate. In the anterior wings 
the acute discoidal cell emits from its apical angle a fork into the apex 
of the wing, two veins to the costa, and three to the hinder margin ;
