DESCRIPTIONS OF NEW NORTH AMERICAN 

 MICROLEPIDOPTERA. 



Hv ArcrsT 

 Duvita, new genus. 



Labial palpi long recurved; second joint thickened with smoothly ap- 

 plied scales, abruptly cut off at apex; terminal joint about as long as second 

 joint, somewhat thickened with scales, smooth, acute. Antennae 4, simple, 

 basal joint without pecten. Forewings elongate ovate, apex bluntly 

 pointed; 12 veins; 7 and 8 stalked to costa; rest separate; 2, 3, 4, and 5 

 equidistant, nearly parallel; Ib furcate at base. Hindwings nearly as 

 broad as the forewings, trapezoidal, apex somewhat produced, termen 

 slightly sinuatcd below apex; tornus rounded; 8 veins; 6 and 7 stalked; 

 3 and 4 connate; 5 parallel to 4; lower part of cell below the fold open. 



Type; Duvita vitella Busck. 



This genus is allied to Aproaerema Dun-ant, differing mainly 

 in the shorter palpi with the sharply cut off second joint and the 

 thickened terminal joint. Aproearema also has the apex of the 

 hindwings much more produced and termen emarginate. Nigra- 

 tomella Chambers and concinusella Chambers, hitherto placed in 

 Aproaetema are referable to Duvita. 



Conclusella Walker, hitherto placed in Gelechia, is also better 

 placed in this genus, though it does not have veins 6 and 7 of 

 hindwings as long stalked as the type of the genus. 



Duvita vittella, new species. 



Second joint of labial palpi blackish brown exteriorly, light ochreous 

 fuscous on the inner side, with the edge of the abruptly cut off apex white; 

 terminal joint whitish with a broad black annulation before the apex. 

 Face whitish. Head and thorax whitish fuscous. Forewings light deer- 

 brown with white markings strongly mottled with steelgray; basal half of 

 costal edge dark brown; a broad ring of mottled white touching the base 

 of the wing and the costal and dorsal margin encloses a spot of the ground 

 color; from the middle of the costa runs an outwardly oblique white mot- 

 tled fascia across the wing; this fascia is sharply denned toward the base 

 of the wing, but is somewhat diffused exteriorly; from apical third of costa 

 runs a parallel thin line of mottled white to tornus; a broad area of the 

 same color along the terminal edge and including apex contains a conspicu- 

 ous small deep black dash on the middle of termen; a thin black white- 

 edged marginal line at base of the steelgray white tipped cilia. Hindwings 

 dark fuscous. Abdomen blackish fuscous above with ligher underside. 

 Legs blackish brown with narrow white annulations on the tarsal joints. 

 Alar expanse: 10-11 mm.
