MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 253
with the transtilla which then is an equally transverse plate with
rising and dilated sides. Vinculum moderate but its parts dilated
and strongly sclerotized. Valva separated in three more or less
isolated sclerites, the basodorsal elongate one being the costa, the
apicodorsal, the cucullus, and the ventral, the sacculus.
Anellus lobe
usually is shifted laterad, connected with the base of the disc of valva.
Aedeagus is short, its base flattened dorsoventrally and curved ventrally,
even rostrally; its top truncate, supported by a slender but
strong ring, open ventrally. Cornuti, seemingly numerous small
spines arranged in a long sheaf, actually are a single, strong, long
pectinate rod! This is evident when a cornutus is ejected, in one
piece, in the bursa copulatrix.
The females have a sterigma diversely shaped in each species and
signum which often is a stellate, dentate plate or a smooth lengthwise
corrugated sclerite; sometimes it is shaped as a "lamina dentata."

Distribution: Philippine Is., Palawan.
The location of the type specimen is not known to me. If it was
at Manila it was certainly lost during the war.
The only additional
material available to me is the female specimen illustrated in figure
