1881,] NORTH-AMERICAN TINEID^. 303 



Ar^olepia, gen. nov. 



Capilli in capite et fronte hirsuti. Palpi labiates breves, articulo 

 secundo incrassafo, supra hirsute crinito, tertio inconspicuo. 

 Atitennce pubescenies. AIcb anticce elongatce, ad angulum analem 

 dilatata; casta nonarcuata; mart/o apical is obliquus, vix concavus. 

 Alee postica sat latce, aliquot acuminata. 



Head rougii above and in front, the scales on the face projecting for- 

 wards 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 con- 

 cealed, well clothed to the apex. 



Fore wings elongate, narrow at the base, gradually widened to- 

 wards 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 

 irom 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^olepia subfasciella, sp. nov. (Plate XXXV. fig. 3, 3«.) 

 Head rough above and in front, white, with a fuscous streak along 

 the middle of the crest. Antennse 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 bel'-w the 

 apex ; the costal and dorsal margins both somewhat bulge 1 near 

 the base. Ground-colour of the fore wings greyish white, pro) \sely 

 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 tiie 

 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.
