 defined; around termen a row of five or six small blackish-fuscous 

 spots. Hind wing and cilia yellowish fuscous. Legs whitish 

 ochreous, lightly suffused with brown. Abdomen light yellowish 

 brown above, whitish ochreous beneath.

 row, weakly sclerotized. Anellus an oval, deeply cupped plate; base 

 strongly sclerotized; lateral lobes stout, exceeding the central plate. 

 Aedeagus large, stout, sharply bent, pointed; vesica armed with one 

 large cornutus and a long, narrow patch of strong slender ones. 

 Vinculum with a prominent, broad, pointed clorsoanterior process.

 ately broad, strongly sclerotized anterior band, which is slightly 

 broader laterally than centrally. Ductus bursae dilated and strongly 

 sclerotized at ostium. Inception of ductus seminalis at about middle
