vertical to vein 2, thence horizontal to vein Ic, thence broadly prominent
and rounded, to vein la and along this vein to base.
Male genitalia: Tegiimen moderate, ovoid, peduncle broad; uncus,
a long slender hook, with a dilated base which is membranous ventrally.
Vinculum rather narrow, V-shaped, saccus strong, clavate-truncate.
Valva elongate, sclerotized, strongly concave longitudinally, sacculus
forming a large and flat fold ^^^th a rounded top, covered with short
bristles. Costal half of valva well defined, costa sinuate at base,
cucullus rigid and sclerotized, forming a pointed blade, with a patch
of very long bristles in disc; there is a third flattened and rounded cusp
below the apical one, supporting a transverse tumescence with dense
long bristles. Anellus erected-quadrate, with httle diverging obtuse
and moderate aneUus lobes. Aedeagus moderate, gTadually slightly
attenuated, rather straight, basal fourth bent down. Cornuti,
numerous small spines. Coremata, two long and slender extensible
hair-pencils in sheaths.
Material examined: Luzon, Los Banos (P. I. Baker), 1 cf , holotype,
genit. slide 5109 (USNM).
Apparently closely allied to ^'Callartona purpurascens" Hampson
from Burma, differing in minor size of yellow markmgs, especially
in the hindwing, where the central spot is less extended in that species.
