middle of termen, opposite apex and on end of costa, respectively,
into three parts; upper of these narrowly elongate and slightly curved,
other large and rounded, lower largest; these three blotches are
interconnected along termen and are ornated with brilliant
silverypurplish
dots, arranged before termen; lower patch with two dots;
upper with two smaller dots in a horizontal series; a well-defined
zigzag whitish line from 4/5 of costa, edging this terminal area anteriorly.
Cilia (imperfect) dark fuscous, mixed with whitish, with
a pale basal line.
Hindwing purplish black; a whitish, outwards-oblique oval ocellus
below costa before middle, reaching to middle of disc, a narrow whitish
inwards-oblique dot on costa before apex, continued by a short
strigula across mng, inwards-obUque briUiant bluish purple; a narrow
subterminal whitish line, from well below apex, parallel to termen as
far as its middle, sinuate inwards thence, to tornus; a vertical brilliant
bluish-purple strigula from costa before apex to 1/3 of termen, narrowed
below. Cilia whitish, basal half black except pale basal line,
apical half with suffused black patches, opposite apex, middle of
termen and tornus, respectively.
Male genitalia: Small and compact. Tegumen rounded. Uncus
broad, truncate, with two brushes of long hairs. Socii are represented
by small folded lateral angles of uncus. Vinculum large,
rounded. Saccus apparently a pointed conical median process,
directed rostrad. Valva small, narrowed, top bilobed, lobes concave,
with sparse short bristles. Aedeagus rather short, not sclerotized,
bulbous, on a narrower stalk, extreme base dilated again, with a
coiled sclerite.
Material examined: Luzon, Mt. Makiling (Baker), 1 cT, holotype,
genit. slide 5172 (USNM). Probably allied with Brenthia quadriforella
Zeller but quite distinct by three, instead of four, lobes of
the black terminal band.
