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 char- 

 acteristic, 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 ex- 

 tremities, 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 oblit- 

 erate 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 sub- 

 basal suffused band and a narrow basal white line.
