from its clothing which consists of dense^ short scales, and is three or 

 four times longer than the apical joint. 



The abdomen in the S is tufted. 



The fold of the fore wings is not closely appressed to the surface and 

 has the appearance of being rolled.- The surface of the fore wings has 

 a rough, peculiar appearance, without, however, having any raised scales 

 upon them. I cannot determine whether it is the same as the furry 

 appearance described as peculiar to Ptijcholoma Leclteana of Europe. 



Ptycholoma ? semifuscana n. s. — Fore wings wliite along the costa and hinder 

 margin, marked with testaceous-brown, ochreous and tarnished silvery stripes 

 and spots. The wing from about tlie middle of the disk to the inner margin is 

 a dark brown or testeceous-brown varied with ochreous ; at the base is an och- 

 reous-brown patch containing a few tarnished or dull silvery spots, and at the 

 anal angle is a large, somewhat obliquely p'aced, quadrate, testaceous-brown 

 patch, margined with ochreous, and this and the basal patch are separated by a 

 dull silvery stripe. The quadrate patch contains numerous, dull silvery spots. 

 On the costa uear the tip is a dark spot of tarnished scales, having on each side 

 an ochreous stripe forming a V, throwing off from its lower part another stripe 

 along the hinder margin. With these stripes alternate others of a dull silvery 

 hue. Cilia whitish. Hind wings dark fuscous. Head brown, somewhat ochre- 

 ous in front. Palpi dark ochreous. AntennsB dark fuscous. 



I have before me three males and one female, all in bad condition, 

 except one of the former. The specimens are from the collection of 

 the Entomological Society of Philadelphia, collected in Virginia, and

Hind wings, the branches of the subco.stal vein 

 are very connivent towards their origin, the lower 

 branch giving origin to the discal vein, which is 

 short and augulated. The median vein is four- 

 branched, the central branch being furcate from 

 tlie middle or near its tip and the superior branch 

 receiving the discal vein at an angle; posterior 

 vein not remote. 



Fore wings, rather narrow in proportion to 

 width ; tip rather acute, the hinder margin beneath 

 it slightly excavated, anal angle rounded obliquely.

 the tip; it should have beeu the middle branch.
