(J. Basal segment of palp orange ventrally, olive-brown dorsally; second segment olive- 

 brown, becoming yellowish grey anteriorly and posteriorly; distal segment olive-brown. 

 Front of head orange, with circular medial patch of yellowish grey bordered by olive-brown; 

 vertex orange with two dark greyish brown medial patches. Shaft of antenna dark greyish 

 brown; scape as shaft dorsally, but yellowish grey ventrally. Patagia orange laterally, with 

 single greyish brown anterior spot, then striped with four longitudinal bands - alternately 

 yellowish brown and greyish yellow. Tegulae yellowish brown with three longitudinal bands 

 of greyish yellow - two marginal (lateral) bands and one central band. Rest of thorax 

 yellowish brown dorsally, with greyish yellow longitudinal band medially, and greyish yellow 

 ventrally. Front surface of fore-coxa orange, with central, yellowish brown patch; fore 

 trochanter, femur, tibia and tarsus yellowish brown with greyish yellow outer edge; mid-coxa 

 greyish yellow with some orange distally; trochanter, femur and tibia yellowish brown edged 

 along inner and outer surface with greyish yellow; mid-tarsus yellowish brown; hind coxa, 

 trochanter and femur as for mid-leg; hind tibia and tarsus yellowish brown. Upper surface of 

 forewing yellowish brown, the veins (including fold of M and Cw 2 ) marked with yellowish orange; 

 sub-apical oblique band yellowish orange, becoming deep yellow at costa. Upper surface of 

 hindwing deep yellow at base, with broad marginal area of greyish brown. Under surface 

 of wings as for upper surface, but ground-colour of forewing less yellowish and unmarked. 

 Dorsal surface of abdominal segments 1 and 2 yellowish brown, with yellowish grey medial 

 band; 3-7 greyish brown with faint dark blue iridescence, and with deep yellow lateral band

$. Similar to <$ but with following differences. Antennae filiform, proximal segments 

 each with single pair of long setae, distal segments with two pairs of long setae. Yellow basal 

 area of hindwing smaller relative to greyish brown margin of wing. Ventral surface of abdomi- 

 nal segments 2-6 edged laterally with dark greyish brown, 7 uniformly dark greyish brown. 



Forewing length: $ 18-0-20-5 mm; $ 21-0-26-0 mm.
