44 THE CANADIAN ENTOMOLOGIST. 
ee ——————————— 
Tongue as long as the anterior coxe. Maxillary palpi short and 
slender ; labial palpi reaching, but not overarching, the vertex, simple, of 
the same size from base to near the apex, the. terminal joint nearly as long as 
the first and second together ; antennæ simple, more than half as long as 
the wings ; scales of the head appressed or smooth. Anterior wings 
elongate ovate, swbfalcate beneath the tip; discoidal cell rather wide, closed, 
the costal vein attains the margin just behind the middle, not far from the 
first sub-costo-marginal vein. The subcostal is straight from its base to 
the costa, just above the tip ; the first marginal is given off just before the 
middle, the second not far behind it, and the third from about the end of 
the cell: & short vein connects the second at about its middle, with the base 
of the third, thus forming a narrow elongate triangular cell, with its base 
resting on the subcostal near the end of the discal cell. The discal (or 
transverse) vein gives off three branches to the hind margin, and below 
them the median is three-branched, the two terminal branches being much 
curved at base. Submedian distinct. Posterior wings a little wider than 
the anterior; costa rather straight, but decidedly retuse before the pointed 
tip; hind (or apical) margin not emarginate beneath the tip, but passing 
with a sweeping curve, like a cimeter, to the dorsal margin. Costal vein 
long and straight ; subcostal long, straight, simple attaining the apex. 
Discal cell wide, closed by a transverse vein, which, near its middle, gives 
off a vein which bifurcates, sending one branch to the apex, and the other 
to the hinder margin ; the median gives off three branches, one before the 
transverse vein, and the two terminal ones arising from a common stalk 
behind it. Submedian and internal veins distinct. The neuration of the 
forewings is thus scarcely different from that of Wyponomeuta, though the 
wing in this species is falcate, and the neuration of the hind wing is 
different. 
IT. ? incertella. NN. sp. 
Palpi bronzy brown, second joint whitish on its inner surface. Head 
silvery. Antenne brown. ‘Thorax reddish or golden brown. Anterior 
wings greyish-brown, with indistinct spots and patches of darker brown, 
the largest of which is about the middle of the costal margin. A broad 
white streak about the basal fourth of the dorsal margin. Apical margin 
densely scaled ; two hinder marginal dark brown lines in the ciliz, one 
at their base, the other and wider one at their apex. Alar ex. nearly % 
inch. Kentucky.
