Figures 286-288, 661-662
Male, 19 mm; female, 20 mm. Head and thorax fuscous grey
(sometimes dark grey) mixed with white (tips of scales), appearing
grey. Palpus creamy sprinkled with dark grey, median segment with
a dark grey spot at base above, another, larger spot at apex above;
terminal segment with a dark grey basal ring and a grey, whitishmixed
median tufted ring, apical half of segment creamy. Antenna
rather thickened in male, grey, scape whitish. Abdomen brownish
fuscous, anal tuft pale ochreous.
Forewdng oblong, broadest at 1/3, costa ciu^ved at base, less curved
in middle, apex rounded, termen rounded, oblique. Pale fulvous
pinkish strewn with blackish-grey scales and blackish-grey raised
tufts. A wedge-shaped basal patch, leaving a narrow edge of dorsum
beyond base unobsciu"ed; two small dark tufts in an oblique row, on
1/4 of costa and in middle of fold, respectively; a more oblique series
of some five points from below the first tuft to fold well beyond the
second tuft; two larger transverse tufts in a series from about 3/5 of
costa to 3/4 of dorsum, first tuft subcostal, second largest, along closing
vein, a group of minute raised scales on dorsum; posterior portion of
wing from before the larger tufts to before apex and termen and not
reaching tornus, denser speckled with dark scales, sometimes a cloudy
triangular greyish costal patch just before apex; terminal edge with a
series of narrow black marginal marks from below apex to tornus.
Cnia concolorous.
Hindwing glossy, pale grey bronze, cilia paler, whitish grey, with a
bronze subbasal shade.
Male genitalia: Rather similar to those of P. zizyphi Stainton
(India) but with harpe ("clasper") more robust and straight, dilated
at base. In P. melanocrepida Clarke (Japan) the clasper is longer and
sinuate.
Female genitalia :
Signum very long and slender, quite distinct from
that in P. zizyphi, where it is moderate, and from that in P.
melanocrepida, where it is short.
