MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 287
Uncus peculiar, bipartite, each half on a slender, angulate stalk, top
dilated into an oval blade with an obliquely produced top. Aedeagus
rather short and wide, apical part narrowed.
The sixth abdominal segment in the female bears at its posterior
portion remarkably shaped corethrogyne structures homologous
with the coremata in the male. This corethrogyne is formed by
three completely expansible tubes, two dorsolateral and one dorsal,
each crowned with a large fan of corrugated long and dense hairs.
These fans can be almost completely retracted inside the respective
tube, and this can be completely retracted inside the sixth segment.
Figure 441 depicts the Philippine specimen with the corethrogyne
in retracted position, figure 440, one of the Coorg specimens, with
these organs completely extruded. Eighth segment with a wellsclerotized
tergite, with a deep and narrow longitudinal median gully,
sternite little modified; ostium rather wide, simple, with a sinuate
lower edge, flanked by two prominences with sparse bristles. Ductus
bursae with a complicated and plicate cestum. Corpus bursae
simple.
The present genus is attributed to the subfamily Nemapogoninae
(Zaguljaev, 1956) the species of which have mycetophagous life
habits (Zaguljaev, 1964), at least in the Palaearctic region. Whether
this is true for the tropical species, remains to be investigated. The
present species has been collected in sugar cane fields in the Philippine
Islands, even recorded "from sugar cane" (label references). I did not
encounter the species in sugar fields in Pasuruan, Java, during an
intense two-years collecting but easily collected it at light in the
jungle. It seems improbable, therefore, that H. subochraccella would
cause any injury to sugar cane. The larvae may live in decaying
mouldy wood.
Haplotinea purpurascens, new species
Figures 462, 788
Male, 25 mm. Head (damaged) and thorax Hght tawny ochreous.
Antenna pale ochreous (damaged). Palpus slender, porrect, rather
short; pale ochreous, median segment except base, fuscous. Abdomen
pale ochreous.
Forewing rather narrow, oblong, suboval-lanceolate, costa little
curved at base, more curved before apex, apex obtusely pointed,
termen rounded, obHque. Glossy pale ochreous, with a faint pinkish
tinge in certain Hghts, especially towards apex; a faint blackish fuscous,
very suffused streak along anterior fourth of costa from beyond base;
a faint elongate patch in posterior half of cell, another in apex, somewhat
denser oclu"eous pinkish, but ill defined. CiUa pale ochreous,
along costa and in apex hght tawny, elsewhere strewn with U ght tawny.
