" Wings broad : fore wing somewhat short, oiitcr margin nearly erect and slightly scalloped ; 

 third subcostal branch bifurcate : hind wing short ; costa abbreviated, lobed at the base, 

 concave towards the end, the apex produced and pointed upward ; exterior margin slightly 

 concave below the apes, and very convex in the middle ; anal angle lobed ; a spatulate tail 

 extending from end of lower median vein ; palpi long, stout, apical joint broad laterally;

 in the male of A. narada." (Moore, I. c.)
