termination at submedian fold ; the antemedial line very slightly 

 angled inwards below costa to meet the subbasal line, then oblique 

 to submedian fold, then incurved, with an indistinct line parallel to 

 its inner edge ; an indistinct medial line double towards costa, oblique 

 from costa to middle of cell, angled inwards on median nervure and 

 vein 1 and outwards in submedian fold ; a white discoidal spot with 

 a dark-edged lunule on it ; the postmedial line bent outwards below 

 costa, angled inwards at vein 5, at vein 3 recurved up to lower angle 

 of cell, then sinuous to inner margin ; a nearly straight subterminal 

 line slightly bent outwards to costa and with some pale rufous on its 

 outer edge ; a fine sinuous terminal line. Hindwing white tinged 

 with fuscous towards termen ; cilia white.

Genus AUTHADISTIS, nov. 



Proboscis fully developed ; palpi porrect extending to just beyond 

 frons, the second joint broadly fringed with scales below, the third 

 short downturned ; frons with conical prominence ; antennae of male 

 bipectinate with long branches, the apical part serrate ; metathorax 

 with large tuft of scales ; abdomen smoothly scaled. Forewing with 

 veins 3 and 5 from near angle of cell ; 6 from upper angle ; 9 from

 3, 4 stalked; 5 from just above angle of cell ; 6, 7 from upper angle ; 

 8 anastomosing with the cell to near middle. 



AUTHADISTIS METALEUCA, n. Sp.

 and with traces of a line on its inner side ; traces of a double sinuous 

 medial line ; the orbicular small, grey, defined by blackish ; the 

 postmedial line black, bisinuate from costa to submedian fold, then
