angulated ; costal and hind margins gently rounded ; surface

 curved but erect, pale ochreous ; second line very erect and 

 almost straight, slender but a little broadened at the costa ; 

 pale ochreous ; costa between these two lines dotted with the 

 same colour ; cilia concolorous. Hind wings broad, rounded 

 behind ; smoky-grey dusted with shining white, and having
