In the Catalogue of the Lep. Phalænæ, p. 528, this species is incorrectly referred to C. venosa. The specimens there recorded are probably all C. venosa, at least those from my collections are. Mr. Geo. Francke sends me two fresh specimens of C. Cressonana. In these, as stated in my original description, Proc. Ent. Soc., Phil., June, 1863, the third stripe of C. venosa is wanting. The stripes on cubitus and branches and along anal region of primaries may vary from white (as I described them) to yellow, and the costa may be yellow (in the first instance)or red. For the yellow-striped from with red costa I propose the name var. Iutea. The fringes in C. Cressonana are entirely white, and I was careful to point out other differences from C. venosa, which should not have been overlooked by the author of the Catalouge above referred to.
