Clemens' description for the purpose of comparison with my own 

 specimens : 



" Head, face, labial palpi and fare fact dark broivn. Antennae dark 

 brown ; basal joint somewhat ochreous. Forewings rather dull dark 

 brown, with a coppery hue. Near the base is a rather narrow, golden 

 band, not constricted on the fald, and rather indistinct toward the costa, 

 where it is somewhat suftused with a coppery hue, and nearest the base 

 on the inner margin. At the apical third of the wing is a small golden 

 spot, and nearly opposite, on the inner margin, another of the same hue, 

 with the hinder portion of the wing tinged with a bright reddish coppery 

 hue ; ciliae dark grayish. Hind wings purplish brown \ ciliae somewhat 

 paler, with a coppery hue." 



The italics are Dr. Clemens'. The following description is drawn 

 from the six bred specimens above mentioned : 



Head and face dark broicn or brilliant metallic, according to the light ; 

 labial palpi yelloicish ivhitc ; tarsi all yellowish white, with each faint 

 tipped luith dark broivn on its anterior margin. Antennae dark brown ^ 

 with the two or three joints nearest the base ochreous, and the extreme tip 

 white. Fore wings and thorax dark brown, blackish, bronzed or tinged 

 with purple, according to the light ; before the middle of the wing is a 

 slightly curved fascia, which is widest and nearest to the base on the 

 dorsal margin, not cofistricted on the fald, but quite distinct throughout. A 

 costal and dorsal streak just before the ciliae, the costal streak a little 

 behind the dorsal one. In fresh specimens this fascia and these streaks 

 are silvery white ; in old sjDecimens they have a faint golden hue in some 

 lights. (Clemens describes them as golden.) Basal half of the cilice- 

 purplish ; apical half g?\iyish silvery. Al. ex. scarcely ^ inch. 



Dr. Clemens suggests that cornifaliella may be a variety of his Nysce 

 foliella. I have never succeeded in breeding the latter species.

I find nearly the same differences between my specimens (bred) of 

 this and Dr. Clemens' description, that I have noted above as to corni- 

 faliella. Dr. Clemens says that the fore wings have no greenish or violet 

 reflections, which is certainly incorrect. The fascia is wider than in 

 cornifaliella, the thorax more shining metallic, the purple hinder marginal 

 line is less distinct, and the entire wing is less purplish, and the species is 

 a little larger. Nevertheless, they resemble each other very closely. The
