the wing, a long, thick rein which arises hehind the middle, and subdivides 

 into three branches at its tip, the apical being forked, with one of its branches 

 delivered to the tip, and the other to the costa before it. The discoidal cell 

 is much elongated and narrow, and sends to the hinder margin a disco-central 

 branch. The median is three-branched at its tip, all of which are short, and 

 the two upper veins arise on a common stalk. Submedian is forked at the 

 base, with the lower branch nearly obsolete. Hind wings narrowly lanceolate, 

 broad at base, with interior basal angle rounded. The subcostal vein is simple, 

 and extended to the tip. Discoidal cell closed by a very faint nervure, giving rise 

 to a simple nervule. Median nervure is three-branched, the last two branches 

 from a common base. 



Head smooth, with decumbent scales, slightly retracted. Forehead broad 

 and rounded ; face, with the scales spreading out at the base of the tongue, so 

 as to make it nearly equally broad. Eyes oval, vertically placed, Ocelli 

 small. Labial palpi very short, smooth ; first and second joints rather thick ; 

 terminal joint pointed, slender, and as long as the second. No maxillary 

 palpi. Antennas setaceous, simple in the V > microscopically pubescent in 

 the (j\ rather more than one-half as long as the fore wings ; basal joint 

 flattened and expanded into a small eye-cap, with cilia in front. Tongue 

 scaled, rather longer than the thorax beneath. 



I have but one male, which is without labial palpi. With the aid of good 

 lenses, I cannot make out whether they have been broken off, or whether 

 they are naturally obsolete. Otherwise, the head is in most perfect condition. 



The genera Zelleria and Ocnerostoma are congeneric with this in the 

 neuration of the wings, especially the hinder pair in the latter genus. 



P. laticapitella . Head, face and thorax shining tawny fuscous. Labial 

 palpi dark fuscous. Antennas fuscous, basal joint tawny fuscous. Fore wings 

 dark fnscons, with a rufous tinge, sprinkled with white, especially toward the 

 tip, with an indistinct whitish band behind the middle of the wing ; cilia pale 

 rufo-fuscous. Hind wings greyish-fuscous ; cilia the same. 



Parasia ? Duponchel. 



Fore wings lanceolate. The subcostal nervure sends three veins to the 

 costa, the first from the middle of the cell, and an apical branch which 

 delivers from its middle a branch to the costa, and is forked before the tip, with 

 one of the branches above and the other beneath it. The discoidal cell is 

 closed, but gives rise to no nervule. The median fan-branched, more 

 separated than in Evagora, and all the branches long. Submedian is forked 

 at the base. Hind wings with the apex produced. The submedian is forked 

 beyond the discal nervure, which gives rise to a disco-central branch. The 

 median is three-branched. 



Head smooth, with loose, decumbent scales. Forehead advanced ; globose, 

 face retreating. Ocelli small. Eyes oval, vertically placed, but little visible 

 from the front. Labial palpi rather short, recurved, smooth, with appressed 

 scales ; second joint thick, subclavate ; third joint short, very acuminate. 

 Maxillary palpi snort, distinct. Antennse simple, setaceous, one-third less 

 long than the fore wings. Tongue clothed with scales, scarcely as long as the 

 anterior coxae. 



This insect and Evagora apicitripunctella certainly approach each 

 other closely in structure ; nevertheless, they are very different in appearance. 

 The hind wings differ from those of Parasia in the produced apex being 

 straight, and slightly in neuration. 



P. ? subsimella . Head, face and thorax ochreous-fuscous. Labial palpi, 

 second joint dark brownish, ringed with whitish at its tip ; third joint white, 

 terminal half black. Antennae dark fuscous, basal joint striped with yellowish 

 in front. Fore wings dark ochreous-fuscous ; along the costa from its middle,
