MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 59 



similar pairs of socii. Caulis usually long. Anellus peculiar, a 

 loose slender ring, encircling base of aedeagus and joined to its lower 

 edge, but also attached at the top to a transverse sclerite between 

 and below socii (gnathos?). 



Female genitalia: Ovipositor of a shape characteristic for the 

 Phaecasiophora group of genera. Lobus analis narrowed above and 

 below, with a gently scalloped edge. Lamella antevaginalis large, 

 transverse, lamella postvaginalis, a small median sclerite. Colliculnm 

 tubular and dark. Ductus bursae rather long, corpus bursae asym- 

 metrically pear-shaped and elongate. Signa one or two spikes or 

 hooks. 



The genus is related with Phaecasiophora group but not with 

 Sisona Snellen. In that genus the hindwing in the male is short, 

 with a projecting lobe at the dorsal angle. The male genitalia of 

 Sisona alhitihiana are quite different and closer to the Hedya type. 

 I hope to publish a figure elsewhere. 



Excepting the type species and that described below, the third 

 species belonging to this genus is the following:

Distribution: New Guinea, Woodlark Island. 



Male, 17-19 mm. Head pale ochreous, forehead between antennae 

 with a vinaceous-brown suffused spot, tufts on vertex vinaceous 

 brown with paler base, upper part of face with an ochreous flat tuft, 

 a pair of purplish spots partly under this tuft at the sides, lower part 

 of face whitish. Thorax pale ochreous sometimes with a faint vina- 

 ceous tinge, marbled with brown. Posterior tibia white, sometimes 

 suffused along dorsal edge with pale oclu-eous grey, dilated and 

 slightly thickened by long glossy white hairs, outer spurs dark grey.
