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 well- 

 sclerotized 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, some- 

 what denser oclu"eous pinkish, but ill defined. CiUa pale ochreous, 

 along costa and in apex hght tawny, elsewhere strewn with U ght tawny.
