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

UiTder 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. Flel)ili.s, it differs in the ground colour of primar.es, being brighter 

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

 white fringe of secondaries. , , •,. ri t-> » 



It is a rare species, aud has generally, heretofore, been confounded with G. Desperata.
