dark brown, with patch of iridescent blue and greenish blue medial and posterior to each 

 antenna. Patagia and tegulae each with broad, oblique, reddish orange or orange (holotype) 

 band; rest of dorsal surface of thorax dark brown with broad, transverse reddish orange or 

 orange (holotype) band towards posterior margin, and with iridescent medial patch anteriorly 

 and on each side of medial line at posterior margin of thorax. Ventral and pleural surfaces 

 of thorax dark brown with some iridescent blue and greenish blue scales. Forecoxa, trochanter 

 and femur dark brown, with iridescent blue and greenish blue along front and outer (lateral) 

 surfaces; foretibia dark brown with longitudinal band of iridescent blue and greenish blue 

 on outer surface, adjacent to epiphysis; foretarsus dark brown proximally, pale brownish 

 yellow distally. Midlegs and hindlegs dark brown from coxa to tibia, with iridescent blue and 

 greenish blue on posterior surface of coxa, trochanter and femur; tarsi pale brownish yellow, 

 with band of dark brown along front surface. Upper surface of forewing reddish orange or orange 

 (holotype), with dark brown at base, in costal area (except at about two-thirds distance from 

 base along costa where orange area extends to costal margin) and in outer marginal band; 

 outer marginal fringe greyish yellow; hind wing orange, with dark brown, distal band. Under 

 surface of forewing similar to upper surface but basal area greyish yellow posterior to costal 

 area, and distally with broad marginal band of greyish yellow; hindwing as upper surface, 

 but costal area dark brown and wing reddish orange anterior to posterior margin of cell and 

 along vein iA. Dorsal surface of abdominal segments i and 2 reddish orange or orange 

 (holotype) medially, greyish yellow laterally with iridescent blue and greenish blue patch 

 posterolaterally on 2; 3-8 weakly iridescent dark brown and dark blue with iridescent blue 

 and greenish blue patches posterolaterally on 3-8 (largest on 7) and medially on 4-8 (largest 

 on 5) ; ventral surface of segment 2 dark brown with area of iridescent blue and greenish blue 

 laterally ; 3-4 reddish orange or orange (holotype) ; 5-7 mainly reddish orange or orange 

 (holotype), with posterior border of dark brown (broadest laterally) and posterolateral patch 

 of iridescent blue and greenish blue on each side; segment 8 dark brown with pair of iridescent 

 blue and greenish blue patches. 



$. As <§ but fringe same colour as outer marginal band on forewing, dark brown outer 

 marginal band of hindwing much broader, and outer marginal band on under surface of forewing 

 narrower, dark brown in colour. 



Forewing length: holotype <J 22-0 mm; paratypes g 20-0-22-5 mm; $ 25-0-26-0 mm. 



^ genitalia (see figure) . Similar to those of docis and viridisignaata.

Probably most closely related to docis from which it is easily separated by the 

 colour-pattern of the wings. 



The name ab. laeta Seitz was applied to specimens illustrated by Rothschild 

 (1910a : 42, pi. 7, figs 36, 41); fig. 36 illustrates the holotype of laeta and fig. 41 

 a paratype of this species.
