Proc. Acad. Nat. Sei., Sept. 1859, p. 257. 
T. acapnopennella. —Fore wings white, with two small spots of fuscous scales 
on the costa near the base, one nearly at the base, the other within the basal 
third. In the middle of the fold is a small spot of brown scales, and obliquely 
above it in the middle of the wing, another of the same hue. Towards the tip 
of the wing is a spot of brown, rather dispersed scales, reaching the hinder 
margin beneath the tip. Cilia white. Hind wings dark gray. 
Antennse yellowish. Head whitish. Labial palpi white dusted with fuscous. 
1 have before me a single specimen, slightly worn. 
The following insects differ in some respects from the genus to 
which they appear to belong, and instead of indicating them as a new 
genus, I have concluded to describe them as a group of the genus 
Tinea. The principal difierence between the members of the group 
below, and the genus, is in the neuration of the hind wings; and even 
here, the type is essentially the same, except that they are so much 
more narrow and differently formed, that the submedian and internal 
veins are obsolete. 
Group HOMOSETIA. 
Hind wings very narrow, linear-lanceolate. Internal border without 
basal angle, costa arched at the basal third^ and concave thence to the 
tip. Without suhmedianor internal veins. The subcostal vein is simple, 
much attenuated, from the middle to the base, and enters the costa 
behind the tip of the wing. The cell is closed by a very indistinct 
discal vein and gives rise to two branches 3 the upper one, sometimes 
attenuated towards its origin, is delivered to the tip of the wing; the 
lower one, sometimes on a common stalk with the superior branch of 
the median vein, runs to the hinder margin beneath the tip. The 
median vein runs near the inner margin, is 3-branched, the posterior 
vein becoming quickly identified with the margin. 
Eore wings narrow, lanceolate. The costal vein almost identified 
with the costa. The subcostal attenuated towards base, and gives off 
at the basal third, a long marginal branch, and from the hinder part 
of the discal cell four branches; the discal vein throws off two branches. 
The median is 3-branched, the posterior, sometimes attenuated at its 
origin, remote from the others. The fold is thickened at its end. 
Submedian, simple.
