tolerably straight, rounded beneath ; bright orange-ochreous ; 

 a silvery-white, internally fuscous-margined, rather narrow costal 

 streak from near base to f, much attenuated towards both ex- 

 tremities ; a broad silvery-white fuscous-margined streak from 

 middle of wing below costa, posteriorly abruptly angulated 

 upwards and ending in apex, rather suddenly attenuated at both 

 extremities ; a broad straight silvery-white fuscous-margined 

 streak from base through middle of wing, posteriorly attenuated, 

 barely or not quite reaching hindmargin ; a narrow silvery-white 

 partially fuscous-margined streak along inner margin from base 

 to anal angle ; a clear dark fuscous line along inner and hind- 

 margins : cilia silvery-white, with two sharp dark fuscous parting 

 lines. Hindwings pale fuscous, more whitish towards base ; 

 cilia pure white. 



Differs markedly from the two succeeding species by the

 inner margin; extreme costal edge white from a little before 

 middle to a little before apex ; a silvery-white blackish-margined 

 streak starting from very near base immediately below costa, at 

 h'rst narrow and parallel to costa, before one-third deflected from 

 costa and continuing parallel to median streak, becoming much 

 broader, its extremity abruptly deflected upwards shortly before 

 hind margin, becoming attenuated, and ending in apex ; a nearly 

 straight broad silvery-white blackish-margined median streak
