MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 61
Female, 17-20 mm. Deeper brownish-tinged throughout. Thorax
denser marbled with dark brown. Abdomen darker brown. Hindtibia
normally scaled, grey.
Forewing narrower and longer, more oval, costa being less distinctly
bent at 2/3 than in male. Costal and apical markings tolerably
similar. Basal patch basically similar, but usually much paler or
hardly defined at all; the same is the case w^ith the pretornal dorsal
spot, but to a lesser degree. (In darker specimens there is some
leaden-black fine marbling in paler interspaces between dark markings).
Hindwing as in male, dorsum normal.
Female genitalia: Eighth segment distinctly sclerotized throughout;
sternite broadly semicircular with a deep excavation. Ostium bursae
cup-shaped, rather broad, sclerotized. Colliculum moderate, narrowed,
about as long as ostium proper. Ductus bursae rather long.
Corpus bursae elongate.
Material examined: West Java: Buitenzorg, 1894, 1 cf, genit.
slide 4552; Batavia, "6^. albitibiana m.," 1 9, genit. slide 4551; Buitenzorg,
1894, 1 cf. (These three specimens from Snellen collection
bear the labels "Grapholitha albitibiana det. Snell." and are recorded
as paratypes of Sisona albitibiana Snellen which species is quite
distinct as is explained below.) Central Java: teak forest near
Semarang, 40 m, 7.VIII.1931, 24.IX.1931, 8.1.1932, bread from leaves
of "Kalak" (family Anonaceae); Seneng, 19.X.1931; Telawa, 8-20.
VIII.1933 and 8-10.1.1935; Gedangan, 13.1.1931, 24.X.1931, and
30.x. 1931, genit. slide 4554 9 (all by L.G.E. Kalshoven). Rembang
Residency, and Semarang, 13.1V. and 3.V.1931 (F.A.T. Verbeek).
20 d', 9 9 (LM).
Belongs to a group of closely allied
species which have been confused
for a long time with Sisona albitibiana Snellen, because of somewhat
similar markings and white-haired tibiae.
Sycacantha inodes perspicua, new subspecies
Figures 71, 533
Male, 18.5 mm. Forewing distinctly longer and narrower. Larger,
more distinctly tinged throughout with pale vinaceous. Pretornal
dorsal spot dark brown, strongly contrasting.
Hindwing with the base of dorsal edge thickened, devoid of hairs,
pinkish-tinged.
Male genitalia:
Identical to those of the nominate form.
Material examined: Luzon, Mt. Makiling (Baker), 1 cT, holotype,
genit. slide 4550.
Although very similar to the material from Java,
this single specimen is sufficiently different to justify subspecific
separation.
