by scaling in upper half. Underside as in metallica, but 

 discal line of fore wing more oblique, a pair of more distinct 

 submarginal lines with whitish interspace, brown submarginal 

 patch E^-Il 2 smaller. Third discal line of hind wing as 

 heavy as or heavier than first and accentuated by vein-dots. 

 Expanse : g 58-64 mm. 



(J. Tenth tergite rather broader than in sinuata and metallica, 

 less convex above, apex more broadly sinuate. Harpe 

 more slender than in metallica, agreeing far better with that 

 of automedon, but shorter.

clay- colour ; a few white battledore-shaped scales laterally 

 at the apices of the third to sixth tergites. Wings somewhat 

 scalloped, fringe dotted heavily with black. Fore wing 

 slightly sinuate below apex ; first discal line not quite straight, 

 ending in a black costal spot just in front of the subcostal 

 fork, third and fourth lines dentate, accentuated with vein- 

 dots ; a brown triangular marginal cloud from R 1 backwards, 

 separating a pale, more or less triangular area from distal 

 margin. Underside : brown, distal border of fore and hind 

 wing dilated before middle ; external discal line parallel 

 with outer margin but curving costad in front, dentate, 

 accentuated with vein-dots. Expanse : q 53-56 mm.,
