domen concolorous with the hind wings. Legs dull ash, ringed with 

 whitish." — PacJcard, I. c. 



The submedian and median veins are flecked with white on the median 

 space in the darker specimens. The ovate ocher spot on the submedian 

 fold in the fuscous shade-band before the anterior line is variable in 

 distinctness.

" In this species the fore wings are long and rather narrower than in 

 the European P. palumhella, and the large broad palpi, though of much 

 the same form, are porrected instead of ascending ; but in venation and 

 the structure of the antennse it agrees with the European species, and 

 Pemjjelia ovalis from New England, in which the wings are much shorter. 

 Body and wings cinereous or granite-gray, the abdomen and legs being 

 paler, and concolorous with the legs and hind wings, which are of the 

 usual glistening hue of the genus. Fore wings of the same ash hue as 

 the thorax, speckled with black scales. Two black dots at the base of the 

 wing below the median vein. Beyond on the submedian vein is a longi- 

 tudinal, blackish, inconspicuous stripe edged on each with dull ochreous. 

 Above it is a dark point on the median and subcostal veins, with whitish 

 scales surrounding the middle dot, but there are no raised scales on the 

 wing. Just beyond the middle of the wing are two, prominent, squarish, 

 black spots, one on the median, the other on the subcostal vein. A 

 distinct, white, submarginal line, parallel with the outer edge and 

 bordered internally with black scales, especially marked on the cos'a. 

 The space between this line and the outer edge is filled in with deep, 

 ochreous, longitudinal bars, alternating with black streaks, of which the 

 costal one is the widest and shortest. These bars do not quite reach the 

 distinct, black line at the edge. Fringe ash, twice lineated with whitish. 

 Beneath a pale, whitish, straight, submarginal line, edged within towards 

 the costa with dark ash.

I have examined the type and two additional specimens, and the neura- 

 tion, which latter should agree with Pempelia, as stated by Packard. The 

 difference between JSfephopteriix and Pempelia does not lie in the neura- 

 tion, but in the structure of the male maxillary palpi.

"Antennae and palpi as in P. fenestrella, but the fore wings are more 

 produced towards the apex, the outer edge being more oblique.^ Body 

 and base of fore wings tawny, the thorax being clay-yellow ; palpi clear
