Hindwing elongate semioval, pointed, under 1, cilia about 1. Vein
2 strongly curved at base, from 4/5, 3 from angle, 4 remote, straight,
5 approximated at base to 4, 6 remote, parallel to 7, accessory cell
distinct.
Female genitalia: Eighth segment erected-conical, broadly split on
venter; edge mesially and caudally bristled. Ovipositor and postapophyses
long, anapophyses moderate. Sterigma, a strongly sclerotized
funnel-shaped projecting structure, with a deeply excised upper edge
and an oblique rib on each side. Ductus bursae very broad, but
moderately long. Corpus bursae ovoid. Signum, two boat keelshaped
sclerites.
Type species: Protorhiza cyanosticta, new species (9)
Superficially suggesting a development of Ethmia stock, but differing
considerably by the presence of a distinct antennal pecten, and by the
position of veins 2 and 3 in both fore- and hindwing, so that a place
in the present family seems more natural.
Protorhiza cyanosticta, new species

irregular, rounded, on closing vein, connected by a patch of denser
irroration with apex. Grey blue suffusion arranged thus: a faint
streak along extreme base of costal edge; three irregular rounded spots
along posterior fourth of costa, faintly extended anteriorly along veins
11-9 and upper edge of cell; posterior parts of veins lc-5 also faintly
streaked with grey bluish. Cilia pale ochreous mixed with fuscous
