Tanaorrhinus, sect. Il. Hampson, Fauna Ind. Moths, Vol. 3, p. 494 (1895). 
Characters, — Face smooth. Palpus in both sexes minute, second joint smooth-scaled. Tongue 
present. Antenna in cf bipectinate to apex, with moderately long branches, in 9 nearly simple. Hind- 
tibia in c not dilated, in both sexes with all spurs. Abdomen not crested. Frenulum fully developed. 
Forewing with costa arched, apex strongly falcate, termen oblique, not convex, cell rather short, 
DC deeply incurved, extremely oblique posteriorly, SC! from cell, anastomosing strongly with C, 
SC? normal, R! separate, M! well separate; hindwing with costal and inner margins rather long, apex 
rounded, termen smooth, rounded, tornus pronounced, cell short, DC? deeply incurved, very oblique 
posteriorly, C approximated to cell for some distance, then rather rapidly diverging, SC? connate or, 
exceptionally, short-stalked with R!, M! well separate. 
Early stages unknown. 
Probably a development of TanorAinus, but entirely different in the palpus, besides some small 
distinctions, one of which Hampson uses in erecting his Section II of Tazaorhinus.
