Show 1881.] NORTH-AMERICAN TINEID.E. 303 AR^OLEPIA, gen. nov. Capilli in capite et front e hirsuti. Palpi labiales breves, articulo secundo incrassato, supra hirsute crinito, tertio inconspicuo. Antenna? pubescentes. Ala? antica? elongata?, ad angulum analem dilatata?; costa nonarcuata; margo apicalis obliquus, vix concavus. Ala? postica? sat lata?, aliquot acuminata?. Head rough above and in front, the scales on the face projecting forwards in a compact tuft; those above the eyes erect and less closely compressed; ocelli present. Antennae slender, pubescent, about half the length of the fore wings ; basal joint short, slightly enlarged. Maxillary palpi none. Labial palpi short, thickly clothed with coarse scales, which project more widely above than beneath ; the second joint somewhat thickened; the apical joint short and nearly concealed, well clothed to the apex. Fore wings elongate, narrow at the base, gradually widened towards the anal angle, which is well defined, especially by the form of the projecting cilia, which give the wing a somewhat hatchet-shaped appearance not entirely due to the wing-structure. The apical margin is oblique, the cilia at the apex slightly rounded. Hind wings about the same width as the widest part of the fore wings, somewhat produced and acuminate at the apex, with very long cilia, especially about the abdominal fold. This genus approaches Plutella (Schranck) and Plutelloptera (Chambers), but differs from the first in the form of the palpi, and from the last in the shape and neuration of the wings. It has no "independent elongate triangular cell," as described and figured by Mr. Chambers (Journ. Can. Soc. Nat. Hist. Jan. 1880, pp. 3-23, fig. 7). AR^EOLEPIA SUBFASCIELLA, sp. nov. (Plate XXXV. fig. 3, 3a.) Head rough above and in front, white, with a fuscous streak along the middle of the crest. Antennae slender, scarcely pubescent, distinctly spotted above with white and fuscous ; the basal joint fuscous. No maxillary palpi discernible. Labial palpi short, the second joint roughly clothed above ; the apical joint short, partly concealed, white above and at the tips, dingy fuscous at the sides and beneath. Fore wings elongate, widened towards the apex, the anal angle somewhat distinct; apical margin oblique, not emarginate beltw the apex; the costal and dorsal margins both somewhat bulged near the base. Ground-colour of the fore wings greyish white, profusely speckled and clouded with greyish fuscous, which is especially collected in two indistinct broken fasciae obliquely inverted, the one from before, the other from beyond the middle of the costa; the second of these is distinctly interrupted beyond the middle of the disk, the dorsal portion being narrower and less conspicuous than the costal; the first is not distinctly interrupted, but the lower or dorsal portion of it becomes suddenly darker than the costal half. Around the apex and apical margin are several square greyish fuscous spots or patches, running completely through the whitish cilia-three costal, |
