Of the species listed in our catalogues those described by Guenee have never before been satisfactorily identified, and several different forms have done duty as Hubner's chalcedonia. By careful comparisons of long series of specimens with the descriptions, I have succeeded in definitely fixing the species intended by both Hiibner and Guenee. At the head of this series comes festivoides, distinguished by shorter, comparatively broader primaries, bright color, and large, oblique reni See Ento. Amer., vol. V, 105, for introduction to this series. E.NTOMOLOG1CA AMERICANA. VOL. V. 6 AUGUST 1869. form, outwardly deeply indented and black marked. In common with the two following species this has a pale apical spot, and a well marked claviform. Chalcedonia is narrower-winged with similar maculation, save that the reniform is smaller, and narrow; the costal region is also pale as a rule. The secondaries are white, hyaline, in both sexes. Exesa is larger and more robust, more evenly colored; but else very like chalcedonia in maculation. The secondaries are fuscous brown. The other species lack the apical pale spot and the claviform, the type of maculation being otherwise the same. Fuscimacula is a very pretty, evenly colored species, grayish fuscous, the lines broad, pale and well defined, and the ordinary spots dusky. Grata, or rasilis as it is generally named, is red-brown, the median lines narrow and white, reniform strongly constricted, with a dusky spot above and below. Paginala is dull, smoky fuscous, the maculation obscure and only the median lines well marked and dark--decidedly different from all allied forms. Versicolor Grt., is known to me in nature, and I have given the description a place next to chalcedonia which...
