band of fuscous atoms in the middle, and at the tip broadly 

 dusted with the same hue. Hind-wings fuscous, cilia the 

 same. 



Antennae dark ochreous. Head shining pale ochreous. 



A single specimen, a male, and, as in other species of this 

 genus, is without labial palpi. 



P. ochreella. Fore-wings, hind-wings, and the cilia of each, 

 shining ochreous and immaculate. 



Antennas russet-coloured. Head and labial palpi ochreous. 

 A single specimen.

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 dis- 

 persed scales, reaching the hinder margin beneath the tip. 

 Cilia white. Hind-wings dark gray. 



Antennae yellowish. Head whitish. Labial palpi white, 

 dusted with fuscous. 



I 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 indi- 

 cating them as a new genus, I have concluded to describe them 

 as a group of the genus Tinea. The principal difference 

 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 in- 

 ternal veins are obsolete.
