Male, 22 mm. Head shining anthracite color (vertex denuded, 

 possibly mixed with pale yellow); orbits yellow; face whitish, 

 mesially pale grey, a dark grey spot on forehead. Antenna blackish 

 above, tawny below, ciliations 1/3, laterally a narrow whitish serrate 

 band, extended into a light yellow ring beyond middle of flagellum 

 which is broad externally, narrowed internally but does not reach 

 apex. Palpus rather long, ascending; pale yellow, median segment 

 with a broad dark grey streak above and laterally not reaching base, 

 terminal segment dark grey externally. Thorax purple, markings 

 pale yellow: a spot on shoulder and narrow edges to tegula; pecten 

 pale yellow. Legs purple, marked with light yellow. Anterior coxa, 

 except top, tibia and tarsus yellow, tarsus mixed with purple above; 

 median tibia and spurs yellow, except a longitudinal spot towards 

 apex above; posterior tibia with two small yellow bands above, under- 

 side and apical tuft with spurs bright orange; tarsus elongate, orange 

 ringed. 



Forewing pale yellow hyaline; costa as far as cell and vein 9 black, 

 so is streak along discoidal vein, which is gently narrowed below and 

 slightly inwards-concave; a minute, yellowish-fuscous line along 

 lower edge of cell from beyond base, continued along and between the 

 approximated veins 2 and 3, and a similar but broader streak along 

 dorsum, both converging beyond cell, to tornus, thence forming a 

 rather narrow oval spot along termen, continued as a narrow marginal 

 band along apex and posterior part of costa to join black costal streak. 

 Cilia pale yellowish olive. 



Hindwing pale yellow hyaline, paler than forewing, a narrow mar- 

 ginal olive-fuscous line throughout. Veins narrowly black. Cilia 

 light olive fuscous.
