Male genitalia : With a short and an extremely long pair of coremata
which when entu'ely retracted reach into the first abdominal segment.
Tegumen slender, uncus pointed, subconical. Anus distinct. Gnathos
bipartite, arms crossed, excurved, interconnected by a membrane.
Saccus short. Valva oval, with a longitudinal high double fold, in
cross section being triangular. Aedeagus straight, very slender.
Type species: Harpeptila corethrodes, new species.
An mteresting genus with the appearance of a large Tineid but with
the wing shape of a Cerostoma. The neuration is peculiar and characteristic,
as are the male genitalia. The affinity of the genus is
uncertain.

Female, 22 mm. Head and thorax pale ochreous tawny mixed
with darker fuscous or brown. Palpus rather long, median segment
exceeding base of antenna, slender at basal half, strongly expanded
posteriorly and with a long porrect brush of rough hairs in front;
basal half of this segment whitish regularly punctate with fuscous,
posterior half with large long subspatulate fuscous scales with white
tips; terminal segment strongly flattened frontally, elongate-suboval,
pointed, erect, 1/2; ochreous whitish, dusted fuscous. Abdomen pale
grey, venter pale ochreous. Hindtibia pale ochreous.
Forewing oblong-suboval, slightly dilated, costa curved at extremities,
almost straight in middle, apex produced and pointed,
termen sinuate, concave above, rounded beneath. Pale ochreous,
very finely irrorated unevenly with dark brown (partly rubbed),
this irroration condensed here and there, so as to form irregular
patches. Edge of costa throughout slightly deeper fuscous ochreous.
An oblique moderate transverse patch or streak from costa before
middle, more or less continued to lower half of termen, entirely obliterate
in cell, beyond cell forming several u'regular blotches, little
interconnected, last blotch fasciate, terminal; a subtriangular spot
on costa before 3/4, more or less connected below with preceding
markings; a dark brown streak in apex, extending over cilia. Cilia
pale ochreous, strewn with dark brown, in and above apex a dark
fuscous-brown blotch connected with apical streak.
Hindwing dark fuscous bronze. Cilia fuscous with a darker subbasal
suffused band and a narrow basal white line.
