Conclusion.—The North American species of this genus may be divided into three Groups, with several sub-groups. Group 1 comprises Pegala and all the larger species. Group 2 Silvestris and others. characterized by their small size, and the peculiar outline of the discal band on under side of hind wings, there being two long serrations against end of cell. This division will throw Meadii into Group 1, in which the band has a rounded prominence against cell. Group 3 comprises Sthenele only.
* It was in 1863 that I named the specimens for Dr. Miles. In 1866 I wrote the paper on these forms which was printed in Proc. Ent. Soc., vol. vi., p. 195. I had brought together a large number of specimens from many localities, and came to the conclusion that Alope and Nephele were two distinct species, and gave my reasons therefor, but I find that I then classed nearly all the variations (now known to be intergrades) with Nephele, using these words: “Alope varies comparatively little, and very little in the direction of Nephele. The variation of Nephele is extreme and in the direction of Alope, but with the greater number of variations close to the type. Occasionally one individual more aberrant than the rest reaches farther towards Alope,” etc.
