straight. Hind wing with the apex rounded, outer margin 

 toothed, with tail-like extremities at terminations of veins 4 

 and 6.

Genus Tanaorhinus, Butler. 

 Tanaorhinus hina, 



cJ . Of a uniform dark shining green colour ; antennae with 

 the shaft green, pectinations dark grey ; palpi black, frons 

 bright ochreous. Wings with pale greenish-white markings ; 

 fore wings with a lunular mark at the end of the cell and a 

 lunular band near the base ; both wings crossed by a discal 

 band of lunules, with a band of lunular spots adjoining on its 

 outer side and a submarginal line of inverted lunules ; cilia 

 white. Underside pale green, the hind wings being slightly 

 tinged with yellow ; fore wings with a black spot at the end 

 of the cell ; both wings crossed by a black macular discal 

 band somewhat near the margin on the hind wing, the spots 

 are joined together more or less, making the band nearlv 

 complete ; on the fore wings the spots are smaller, not 

 together, and double as they go upwards ; marginal line 

 black, cilia white ; body pale greenish grey, legs green, tarsi 

 with black bands. 



Expanse of wings 1to-2 inches.

Allied to T. divii'ssa, Walker, xxii. 516, but much smaller; 

 can easily be distinguished by the difference in the markings 

 below, the latter having a nearly straight black band from 

 the abdominal margin of hind wings a little beyond the middle 

 to the costa of fore wings near the apex ; the submarginal 

 band of dimissa also is very differently situated and does not 

 extend up the fore wings.
