cf 2 • Upperside bright ochraceous yellow, spotted and marked 

 with black. Fore wing : cell crossed by three short sinuous lines 

 and one along the discoeellulars, a series of spots beyond, bent 

 inwards below interspace 4 and continued immediately below the 

 median vein, followed by two transverse series of discal spots, a 

 postdiscal series of continuous lunules, a subterminal slender line, 

 and a terminal series of spots at the apices of the veins. Hind
