Under side of primaries dark brown, grayish at base and over apical area, more particularly when seen obliquely. Secondaries gray-brown, caused by a uniform sprinkling of whitish scales over the brown surface; without spots except a transverse abbreviated white dash on middle of disk. Female—Color of the male; the white spots conspicuous, forming a discal row quite across primaries; a large spot in cell, and a small one in submedian interspace near base. Under side of both wings as in the male, except that the three costal spots of discal row are repeated, and the spot in cell, but all are reduced. From one male and one female taken in Montana by Mr. Morrison, 1881. In all four examples were taken. We have not tken it, nor have we seen any specimens we could refer to the species. Dyar says he has not seen any certainly determined specimens. Genus PHOLISORA, Scudder. The Sooty-wing, Pholisora catullus (Phol-i-so'ra ca-tul'lus) Plate XII, and Fig. Fig. 107. Pholisora catullus, slightly enlarged. Butterfly—Expanse, .80 to inches. Brownish black on both sides of the wings, with a faint marginal series and a conspicuous submarginal series of light spots on the primaries. In the male on the upper side, and in addition to these, in the female, a faint marginal series on the sec- ondaries. On the under side only the upper spots of the submar- ginal series of the primaries reappear. The body and head are black above, the head with three longitudinal white stripes, the ends of the palpi hairs the same color; the palpi and head white beneath, the body blacfl. Fringes concolorous with the wings. Early Stages—The larva feeds on Monarda, Chenopodium, Ambrosia, and others. It forms a case for itself by folding the leaf along the mid- rib and stitching the edge together with a few threads of silk. It lies concealed during the day and feeds at night. Distributio
