204 PROCEEDINGS OF THE ACADEMY OF 



C. caliginosellus . Head, thorax and labial palpi dark fuscous. Fore 

 wings dark fuscous, with two angulated umber brown lines, one about the 

 middle of the wing, and rather indistinct, and one near the hind margin ; on 

 the hinder margin is a blackish brown line ; cilia fuscous. Hind wings rather 

 dark fuscous ; cilia whitish. 



C. mutabilis. Grayish fuscous, varied beneath the fold with luteous. 

 Labial palpi dark fuscous. Fore wings with a grayish median stripe, not ex- 

 tending beyond the disk, more or less tinted with luteous beneath the fold, 

 and with fuscous along the base of the costa. On the end of the median ner- 

 vure is a dark brown dot, and sometimes streaked with dark fuscous beneath 

 the nervure. The subterminal line is faint and bluish, usually containing a 

 row of faint brownish dots. Hind wings yellowish, gray or pale fuscous. 



This species appears to be highly variable, the general hue being sometimes 

 pale ochreous, and in specimens somewhat worn, scarcely to be identified. 



C. vulgi vagellus. Labial palpi luteous, dark fuscous externally. 

 Head and thorax luteous ; teguloe with a fuscous stripe. Fore wings luteous, 

 with numerous fuscous streaks in atoms, along the veins and two in the disk. 

 Hind margin with a row of terminal black dots ; cilia golden hued. Hind 

 wings yellowish ; cilia whitish. 



C. albellus. Pure white, with a row of black dots on the hind margin 

 of the fore wings, with an oblique pale yellow acutely angulated line from 

 near the middle of costa, and an angulated silvery subterminal line margined 

 on both sides with pale yellowish. Above the marginal dots at the base of 

 the cilia is a short blackish marginal line. Hind wings pale brownish -gray or 

 whitish. 



C. elegans. Whitish. Fore wings at the base of costa ratheT broadly 

 streaked with brown, having a brassy lustre, with a patch of brown scales on 

 the inner margin near the base, and a short, curved streak of the same hue 

 about its middle, which forms with its opposite when the wings are closed a 

 semi-circular dorsal line, behind which the wing is dusted with brown. On 

 the apical third of the wing is a broad, brown band, broadest on the costa, 

 where it encloses a small white spot, and with a straight brown subterminal 

 line exterior to it, on a silvery white ground. The hinder margin is dotted 

 with black points ; cilia silvery. Hind wings pale brownish white. 



Variety. Costa slightly touched at the base with dark fuscous. No distinct 

 broad band on the apical third, but the costa from nearly the middle, dark 

 fuscous, containing two small, white costal spots. The subterminal line 

 whitish, margined on each side with fuscous. The spot on middle of inner 

 margin rather diffuse, not linear, and the wing behind it but little dusted. 

 Hind wings whitish. 



C. Girardellus. Labial palpi pale fuscous externally, above and be- 

 neath silvery white. Fore wings silvery white, with an orange yellow stripe 

 beneath the median nervure, somewhat turned upwards at its tip toward the 

 apex of the wing, and extended on the sides of the thorax to the head ; it is 

 slightly margined toward the costa of the wing with dark reddish fuscous. 

 The hind margin is dotted with blackish dots, and at the base of the cilia is a 

 dark brown marginal line ; cilia silvery. Head wings white. 



Mass. From Dr. Chas. GHrard. 



C. auratellus . Labial palpi and antennae orange yellow, the former 

 silvery white above. Fore wings silvery white, with an orange yellow band, 

 from the apical third of the costa to the middle of inner margin, where it is 

 broadest, and somewhat produced along the costa toward the tip, and the 

 inner margin to the anal angle. Cilia orange yellow, with a dark reddish 

 fuscous, somewhat crenated basal line. Head wings white. 



Mass. From Mr. S. H. Scudder, Jr.
