rowed in middle. Vinculum large, broadly rounded. Valv^a very
large, costa and cucullus portion membranous, making \\dde and
undulating folds (only partially expanded in mount) ; sacculus part
moderately broad, rigid, ending in a triangular lobe. Sacculus proper
narrow, dilated posterad, top sclerotized, subobtuse. Aedeagus with
a truncate top and a peculiar subapical denticulate and curved thorn.
Cornuti, a sheaf of some three very long spines.
Female genitalia: Ostium and coUiculum together forming a long
simple funnel, with a moderately sclerotized, slightly wrinkled wall;
a slight, paler constriction indicating the connection of ostium with
coUiculum ; low^er extremity of this funnel obliterate in front. Ductus
bursae rather long, with two coils, with a very thin cestrum. Corpus
bursae inverted. Signum, an obliquely striped rather long dagger.
