Trans. Am. Ent. Soc, Vol. IV., ]>. 20, (1872). 



(PLATE IX, FIG. 1, c?.) 



Expands 2J inclu's. 



Head and thorax, above, whitish grey ; abdomen blackish. Beneath, thorax white, abdomen white, 

 powdered witli grey atoms. 



Upper surface ; i)riraaries whitish grey; transverse shades very faint; transverse hnes narrow and black; 

 rcniform ordinary size ; sub-reniforra open. 



Secondaries black, greyish at base; fringes white. 



Under surface; i)rimaries black; a small white basal patch; a narrow white, sub-terminal band which 

 becomes almost obsolete towards the interior margin ; a white median band extending from costa to half way 

 between the latter and interior margin. 



Secondaries, basal third white, rest black with a narrow white mesial band. Fringes on all wings white. 



Habitat. New England, Middle and Western States to the Mississippi. 



Somewhat rare, and distinguishable from all other black-winged species by the peculiar pale frosted 

 appearance of the uj^per surface of primaries.

(PLATE IX, FIG. 2, (?■) 



Expands 2f inches. 



Head and thorax, above, grey ; abdomen blackish grey. Beneath white. 



Upper surface; primaries light grey, transverse lines black and distinct; reniform surrounded by a 

 double line; black sub-apical dash; two other black dashes, one crossing the transverse anterior line, and the 

 other the transverse posterior line, towards the interior margin. 



Secondaries black, with broad white fringes. 



Under surface nearly the same as in C. Desperata, to which this species, though smaller, is closely allied. 



Habitat. New England, Middle, and doubtless other of the United States. 



Compared with C. Desperata and C. Flebilis, it differs in the ground colour of primaries, being brighter 

 and of a less bluish cast; the black shades sharper, not so spread or suffused; and in the greater depth of the 

 white fringe of secondaries. ■ \ n t\ 



It is a rare species, and has generally, heretofore, been confounded with C. Desperata.
