(14) Thecla calanus, Hübner, Plate XXIX, Fig. 26, ♁; Plate V, Figs. 25, 27, chrysalis (The Banded Hair-streak).
Butterfly.—On the upper side resembling the preceding species very closely, but a trifle darker, and warmer brown. On the under side the wings are marked by fine white lines on the outer half, which are not broken, as in edwardsi, but form continuous bands. Expanse, 1.15 inch.
Early Stages.—The caterpillar feeds on oaks. The life-history is described with minute exactness by Scudder in "The Butterflies of New England," vol. ii, p. 888.
This insect has a wide range, being found from the province of Quebec to Texas and Colorado. It is common in western Pennsylvania.
(15) Thecla liparops, Boisduval and Leconte, Plate XXIX, Fig. 28, ♁, under side; Plate V, Fig. 28, chrysalis (The Striped Hair-streak).
Butterfly.—Dark brown on the upper side, grayish below. The lines are arranged much as in T. edwardsi, but are farther apart, often very narrow, scarcely defining the dark bands between them. The spots at the anal angle are obscure and blackish. Expanse, 1.15 inch.
Early Stages.—Much like those of the allied species. Scudder, in "The Butterflies of New England," gives a full account of them. The caterpillar feeds on a variety of plants—oaks, willows, the wild plum, and other rosaceous plants, as well as on the Ericaceæ.
It ranges through the northern Atlantic States and Quebec to Colorado and Montana, but is local in its habits, and nowhere common.
