segment and its apex pointing towards middle line, the 

 space separating the apices equal to about one-fourth of 

 total width of segment, lateral triangles in contact with 

 front margin of segment for more than half their extent, but 

 not quite reaching hind margin. JVings : mummy-brown 

 markings of same type as wing-markings of foregoing species, 

 but transverse band not connected with nmmmy-brown 

 streak in apex of anal cell, and apical blotch not reaching 

 posterior branch of third longitudinal vein ; extreme base 

 and costal cells raw sienua-colourcd, proximal extremity of 

 second costal cell tinged with mummy-brown ; stigma ochra- 

 ceous, its distal extremity mummy-brown; in proximal half 

 of wing a mummy-brown blotch extends obli([uely across 

 bases of first and second basal cells and anal cell, and is 

 narrower in latter, in first basal cell leaving usual minute, 

 elongate, hyaline streak in extreme base next upper margin ; 

 there is also a transverse mummy-brown streak in apex of 

 anal cell, next posterior branch of fifth vein ; in distal half 

 of wing mummy-brown transverse band, starting from hind 

 margin in fourth posterior cell and overflowing somewhat 

 into fifth posterior cell, runs obliquely forwards to costa, 

 along which it is continned into second submarginal cell ; 

 proximal margin of transverse band runs at first in fifth 

 posterior cell, nearly parallel to posterior intercalary vein ; 

 crossing latter and fourth posterior cell at a point about one- 

 fourth of their length from base, it is indented in discal cell, 

 and reaches stigma at a point about one-third of the length 

 of the latter from its proximal extremity; distal margin of 

 transverse band (in typical specimen at any rate) slightly 

 sinuous, bulging forwards in first posterior cell, and turning 

 towards tip of wing just below second longitudinal vein ; 

 apical blotch reaching not quite half-way into second sub- 

 marginal cell ; costa, auxiliary, and first longitudinal veins 

 mummy-brown, other veins ochre-yellow or orange-buff, 

 mummy-brown in portions included in dark markings, 

 Jlalteres : knobs russet-brown, stalks buff. Legs : front coxae 

 ochraceous-buff, poUinose, clothed with pale yellowish hair; 

 femora and middle and hind coxse mummy-brown, former 

 clothed with ochreous hair, tips of femora cinnamon ; front 

 tibisc ochraceous-buff, darker at distal extremity, hind tibiae 

 buff, tawny-oehraoeous at extreme tip on inner side (middle 

 tibiae and tarsi wanting in case of type) ; last four joints of 

 front tarsi dark brown, first joint brown, lighter (tawny) at 

 base ; hind tarsi buff, last two joints and extreme tips of 

 first three joints cinnamon-rufous; front tibia? clothed with
