Imago. — <$. Metanotum with a black mesial dot and a reddish- 

 tawny lateral spot ; sides of abdomen with a broad blackish 

 stripe, broadest and most distinct at base, dorsally bordered 

 on segments 3 to 7 by a rufous-red stripe. Fore wing with 

 a single white submarginal line, which consists of half-moons, 

 the horns of which point discad. Hind wing with a sharply 

 defined buff band, reaching to SC 2 , indented at R 2 , with 

 four brown dots, the last two, on M 2 and M 1 , touching the 

 black basal area or fused with it ; fringe with white scales 

 at least between M 1 and M 2 , besides the white scaling at anal 

 angle. Underside pinkish -red, the black basal area of fore 

 wing reduced to a streak or patch behind cell, not entering 

 cell ; wings showing distally traces of the ochreous ground- 

 colour. Second segment of palpus not narrowed towards base ; 

 cavity of first segment distinct but not large. External 

 row of spines of first protarsal segment simple or irregularly 

 doubled at base. Antenna longer and thicker than in velata, 

 acuta etc., the black apical scaling confined to the last two to 

 six segments. Expanse : ^9 72-86 mm. 



Harpe nearly as in olivacea. Penis-sheath (fig. 120 E) also 

 as in that species, but the left process reduced to a few teeth.
