Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 stalked.
