hardly denticulate. Tongue of moderate length, clothed with scales. 
Maxillary palpi very short. Labial palpi of moderate length, reflexed ; 
the second joint long, with appressed scales; the third joint short, with 
appressed scales, the extreme apex only being smooth and pointed. Aunte- 
rior wings elongate; posterior wings trapezoidal, deeply emarginate be- 
low the apex, with long cilia. In the anterior wings the apical vein is 
trifid, two branches running into the costa and one into the hinder 
margin, below it are fowr veins from the discoidal cell. In the pos- 
terior wings the simple apical vein terminates iz ¢he prolonged apex ; 
below it are two veins from the transverse vein; the costal cell termi- 
nates before the middle of the wing. 
But few species (only four British) are yet known in this 
genus; but from the extremely retired habits of the perfect m- 
sects of those that have been met with, it is by no means impro- 
bable that several other species may hereafter be detected. Pa- 
rasia Lappella was a varity, and but in few collections, and had been 
bred by no English collector, at the time that the authoress of the 
‘Bpisodes of Insect Life’ yublished a notice of the habits of the 
larva. Parasia Carlinella was entirely unknown till Mr. Douglas 
bred it in abundance from the heads of Carlina vulgaris, gathered 
at Folkstone, in December. 
The mode of feeding of the larvae of these species is very dif- 
ferent; both feed, it is true, in the heads of Composite plants, 
but that of Zappella feeds on Arctium Lappa, eating through the 
seeds (precisely resembling in habit the larva of Ge/echia bifrac- 
telia), whereas the larva of Carlinella, feeding in Carlina vulgaris, 
leaves the seeds untouched and devours the receptacle below the 
seeds. The habits of the larvee of P. Metzneriella and neuroptedla 
are not yet known.

Head and face ochreous. Palpi pale ochreous, beneath darker. An- 
tenn fuscous, with darker annulations. Anterior wings ochreous, with 
a long patch at the base of the costa, a small spot on the costa before 
and one beyond the middle, brownish; the hinder margin is suffused 
with pale brownish; several of the veins appear grey; on the disc are 
three black spots (one on the fold before the middle, one beyond it nearer 
the costa, and one at the end of the discoidal cell) ; cilia pale ochreous, 
darker near the hinder margin, Posterior wings grey, with ochreous- 
grey cilia.
