the hind wings have 4 and 5 from a common stalk, connected by a short 



vein with 3, sweeping by and forming the cross-vein. 



Until the structure of our species can be carefully 

 compared with the European, it will be better to refer 

 to this genus all forms which combine the peculiarity 

 of the male antennsB here described with untufted 

 male maxillary palpi, and 11-veined primaries, on 

 which 4 and 5 have a separate origin, and 8-veined 

 secondaries. There is no doubt that Dr. Packard 

 has incorrectly used the term "PempeZm" through- 

 out, and probably also the present generic term. 

 ■^'^•^' His N&pJwpteryx roseatella does not belong here. Dr. 



Packard's generic determination of the female of ovalis carries no 



weight; for, in this genus and its allies, the female does not possess the 



essential characteristics.

 specimens. There is not a particle of doubt that Dr. Packard has 

 described the sexes under distinct genera, and thus taken the sexual 

 characters as generic, although the male has no characters of Pempelia 

 except the bent and tufted antennse. The two specimens, and descrip- 

 tions for that matter, are otherwise almost exactly the same. The 

 female described by Dr. Packard wants the ochery submedian streak, 

 which, where it cuts the dark band before the anterior line, usually ex- 

 pands into a more or less well-marked spot. In some specimens of 

 either sex, this ocherous mark is almost wanting. My material has been 

 mostly sent me from Maine by Mr. Fish and Professor Fernald. 



"Palpi large and broad, antennse tufted at base as usual, fore wings 

 oblong, not very long, outer edge less oblique than usual. Body and 

 fore wings ash, being covered with whitish and brown scales. Fore 

 wings with a short, curved, dark line at base on the median vein. On 

 inner third of wing a very broad brown band, directed obliquely out- 

 ward from the costa to the inner edge, and enclosiug a large distinct, 

 regularly oval (longitudinal), ochreous spot between the median and sub- 

 median veins. Two obscure black discal points situated as usual; 

 the outer one is enclosed in a dusky shade crossing the wing obliquely 

 and limited beyond by the usual submarginal zigzag line, this line is 

 curved inward below the costa ; from the middle of the wing to the inner 

 margin it is exactly parallel to the outer edge, terminating in an angle 

 directed outwards. Between this line and the edge is a series of dusky 

 bars, the interspaces cinereous. A marginal black line. Fringe cinere- 

 ous. Hind wings pale smoky. Beneath fore wings dusky. A whitish 

 costal spot near the apex, but no line. Hind wings slightly paler. Ab-
