Female. Body rather slender. Proboscis short. Palpi porrect, broad, obtuse, thickly clothed with short hairs beneath, shorter than the breadth of the head; third joint very minute. Antennae slender. Abdomen extending much beyond the hind wings. Legs rather long, moderately stout; spurs long, slender. Wings long. Fore wings narrow, hardly acute; costa hardly convex; exterior border slightly convex, very oblique.[3]
