Characters. — Head with dense rough hairs. Antenne two-thirds to nearly 1, submoniliform, 
basal joint short. Labial palpi obsolete. Maxillary palpi long, several:jointed, folded. Posterior tibiz 
with spurs placed in groups of spines. Forewings with ra running into 12, forming long basal furcation, 
ic well-defined, connected with lower margin of cell by bar near base, 2 and 3 approximated, forked 
parting-vein well-defined, rising out of lower margin of cell near base, terminating in 4 and 5, between 
which transverse vein is absent, secondary cell defined, 7 separate, to costa, 11 from one-third of cell, 
sometimes connected by bar with 12, r2 giving rise to an additional branch (13) above in middle. Hind- 
wings under 1, ovate-lanceolate, cilia 1; neuration as in forewings, but ra out of 1b near base, diverging, 
2 and 3 remote, r2 without additional branch.
