of costa, first of these small, second continued as a strong, inwardsoblique,
slightly curved transverse fascia to 3/4 of dorsum, broadly
interrupted below middle, so as to form a semioval isolated spot on
dorsum; thu'd costal spot apical; some blackish suffusion before termen;
a black narrow line along lower fourth of termen and in tornus;
some faint ferruginous suffusion along base of dorsum; a couple of
black dots on middle of dorsum. Cilia whitish green, in apex white.
Hindwing dark grey, cilia pale fuscous greyish, glossy.
Female, 20 mm. Marldngs similar to those in the male, but instead
of a costal fold there is a small spot on costa beyond base and a
larger outwards-oblique spot on 1/4. Palpus light green, median
segment with a transverse sparse brownish dusting.
Male genitalia: Uncus broadly truncate, with membranous lateral
flaps. Socius, a large, inwards-curved arm. Gnathos, a sclerotized,
erected-trapezoidal plate, constricted below top, lower edge with a
split in the middle and small emarginations at the sides. Valva
strongly narrowed in middle, cucuUus sinuate, slender; saccidus with
a small median prominent process.
Female genitalia: Genital ven trite sclerotized. Sterigma formed by
a median suboval aciculate mold, surrounded by a furrow, being the
ostium bursae. Colliculum, an irregular sclerite with longitudinal
folds, occupying almost the entire ductus bursae, which is short.
Signa rather small unequal straight thorns with moderate basal
plates.
