Forewing rather narrow, outer margin sinuate, apex acute; R1, from hefore apex of cell; R3, from apex, closely approximated to R3 + 4; R3 and R4, stalked for about three-fifths of their length; R5, straight and well-separated from R3 + 4; M1 from behind anterior angle of cell; discocellular weakly angulate; M2, M3 and Cu1, arising fairly close together around posterior angle of cell; M3 and Cu1, weakly approximated basally; Cu2 from cell rather close to angle; anal loop large and complete. Hind wing with outer margin weakly sinuated; Sc and Rs, strongly anastomosed; Rs, hardly stalked with M1; cell short, discocellular weakly angled in middle; M2, M3 and Cu1 from posterior angle of cell, approximated basally; Cu2 from very close to angle of cell; three anal veins present.
