Antennae of male bipectinated, usually with long branches. Tibia with long spurs, where the outer spurs about two-thirds the length of the inner. Forewings long and narrow, with rounded apex. Vein 3 from near angle of cell and veins 4 and 5 usually on a long stalk. Veins 6, 7, 10 and 11 free. Hindwings with vein 3 from near angle of cell and vein 5 absent. Vein 6 obsolescent from above middle of discocellulars and vein 7 anastomosing (fusing) with vein 8.[1]
