There is also a postmedial white spot on the costa with an excurved line from it to vein 4, then almost obsolete and retracted to a white patch on the inner area below the end of the cell. There is also a white subapical point and a slight subterminal line between veins 7 and 4. The hindwings are black brown tinged with yellowish and slightly suffused with grey.
