Antennae blackish. Palpi and head orange -ochreous. Thorax 

 orange-ochreous, with two longitudinal blackish streaks; tegulae 

 blackish, edged with orange-ochreous; pectus blackish. Fore- 

 wings broad, costa rather strongly arched, apex rounded, not 

 oblique; 7-8 stalked, 8 to apex; orange-ochreous, the inter- 

 neural spaces strongly marked with black, causing the neuration 

 to appear conspicuously in lines of the orange ground-colour, 

 except toward the costa and termen where the ground-colour 

 forms a subterminal band obliterating the black streaks, with 

 the exception of the two preceding veins 11 and 12 which extend 

 to the costa ; the black streak between veins 5-6 differs from the 

 others in widening inwardly, ending with a lunate expansion on 

 the discoidal and is not connected with the black discal streak; 

 the costa and termen are narrowly margined with black, the termen 

 with a narrow lilac-grey line at the base of the dark fuscous cilia; 

 underside pale orange-ochreous, the costa and termen margined 

 with dark fuscous, with some blackish interneural shading. Exp. 

 al. 34 mm. Hind-wings orange-ochreous, with a broad black basal 

 patch, and narrowly black at the apex and along the termen ; the 

 black basal patch extends to beyond the cell and is irregular in 

 outline, having four or five tooth-like extensions along the veins; 

 cilia orange-ochreous, black at their base at the apex and along the 

 termen; underside as above, but with an orange-ochreous streak 

 in the cell above the media and the black terminal line extending 

 to vein 2. Abdomen blackish, pale orange-ochreous beneath. Legs 

 orange-ochreous, outwardly shaded with fuscous.
