Extract

In the Am. Nat., Sept., 1872, Mr. Scudder published an essay entitled “The curious History of a Butterfly,” in which it is stated that in two N. American species of the “genus Brenthis,” namely, myrina and bellona, occurs a phenomenon considered by the author to be quite unique among butterflies : there being two sets of individuals, each following its own cycle of changes,:apparently with as little to do with the other set as if it were a different species; each set having its own distinct seasons and thus giving rise to the apparition of two or three successive broods in the course of the year.

* Though there are some reasons for suspecting that in West Virginia the other species must be double brooded also. That, however, is not determined, and I do not assume it. But this difference in the same genus as regards the number of broods, supposing it exists in Argynnis, is paralleled by the Apaturas celtis and clyton, the former being here double, the latter single brooded.
