Show 1881.] NORTH-AMERICAN TINEIDiE. 315 longed on the costal third nearly to the middle of the wing, distinctly margined beneath it by a strong reddish shade, outwardly diffused and blended with the paler (more greyish) apical half of the wing; the costa slightly speckled with reddish grey ; two blackish discal spots of raised scales scarcely beyond the basal third, the lower one being the furthest from the base and slightly elongate ; beyond these, about the end of the cell, is a whitish dot, surrounded by a few fuscous scales, sometimes preceded by a similar but even less conspicuous dot on the cell; some fuscous scales are distributed around the apical margin. Cilia dull reddish. Hind wings whitish grey, with rather rosy cilia. Expanse 21 millim. Five specimens taken near Fort Klamath, in Oregon, in the autumn of 1871. One only is in good condition. This species appears to be allied to Depressaria ciniflonella (Zeller), to which it bears some resemblance; but it is less mottled, and has more red about it; moreover the fore wings are less attenuated and elongate. DEPRESSARIA POSTICELLA, sp. nov. (Plate XXXVI. fig. 5.) Capite et thorace subochraceis ; palpis concoloribus, articulo se-cundo externe fusco adsperso; antennis fuscis; alis anticis subochraceis, rufo paulum suffusis, fusco irroratis, puncto disci ante medium fusco, punctis marginalibus diffusis fuscis, nebula ante angulum analem {disci dimidium costale nunquam attin-gente) fusca, ciliis subfuscis (aliepuando subroseis). Head and thorax rather dull ochreous ; palpi of the same colour, sprinkled externally on the second joint with fuscous; antennae fuscous. Fo-re wings rather dull ochreous, sprinkled with fuscous scales, and somewhat suffused with a reddish tinge in some specimens, with a small fuscous spot at the base of the costa; a fuscous dot on the cell before the middle, some diffused fuscous dots along the apical margin, and a fuscous cloud or blotch before the anal angle, reaching from the dorsal margin nearly to the middle of the wing, but not attaining the costal half. Cilia with a fuscous or a rosy tinge in different specimens. Hind wings greyish ; the cilia rosy; the anal tuft sometimes rosy. Expanse 18-21 millim. I met with this species in Lake county, California, on June 15 and June 30, 1871, and in Southern Oregon in M a y 1872. I also bred a specimen from among larvae, feeding together with those of another species of Depressaria (psoraliella) on Psoralia physodes (Dough), the larva being found in Mendocino county on May 24, the perfect insect appearing on June 13. I am indebted to the kindness of Prof. Henry N. Bolander, of San Francisco, for the determination of this and other plants mentioned in this paper. The species differs from Depressaria angelicella, Hub. (Staud. & Wocke, Cat. n. 1736), in the absence of a dot on the fold, and in the 21* |
