This genus is large, and is well represented in Asia and the Indo-Malayan region. I cannot see any good ground for generically separating the two species found in North America from their congeners of Asiatic countries, as has been done by some writers.
(1) Debis portlandia, Plate XVIII, Fig. 20, ♂; Plate III, Fig. 16, larva; Plate IV, Fig. 6, chrysalis (The Pearly Eye).
Butterfly.—The butterfly, the male of which is well depicted as to its upper side on the plate, does not differ greatly in the sexes. The hind wings on the under side are marked with a series of beautiful ocelli. In the North the insect is single-brooded; in the region of West Virginia and southward it is double-brooded. Expanse, 1.75-2.00 inches.
Early Stages.—The illustrations give a good idea of the mature larva and the chrysalis. The caterpillar, like most of the Satyrinæ, feeds upon grasses.
The range of this pretty insect is extensive, it being found from Maine to the Gulf of Mexico, and westward to the Rocky Mountains.
(2) Debis creola, Skinner, Plate XVIII, Fig. 18, ♂; Fig. 19, ♁ (The Creole).
Butterfly.—Easily distinguished from the preceding species by the elongated patches of dark raised scales upon the fore wings, situated on the interspaces between the median nervules. The female has more yellow upon the upper side of the fore wings than D. portlandia. Expanse, 2.25 inches.
Early Stages.—Unknown.
Creola ranges from Florida to Mexico along the Gulf.
