DESCRIPTION ( FIG. 6E–H ) Antennae short-bipectinate, serrated at apex in the male, filiform in the female, flagellum with ochraceous scales.

Abdomen cartridge-buff irrorated with fuscous. Legs ochreous, fore femur and tibia strongly infuscated on their inner surfaces. Forewings ochreous suffused with fuscous scales; an antemedial black spot below the cell; a longitudinal ochreous fascia from base along lower margin of cell, partly within, partly without cell limited to the first two-thirds of the wing and a postmedial row of spots. Fringe bright ochreous with a basal black line. Hindwings white, veins with cartridge-buff scales; fringe white iridescent. Underside of forewings pale cartridgebuff at the base, cartridge-buff on costa; apex and terminal area heavily suffused with fuscous, with cartridge-buff scales along the veins. Underside of hindwings white, costa and apex suffused with fuscous scales; fringe white iridescent with a basal cartridgebuff line. Wingspan 32–34 mm (males) ( n = 8); 35–44 mm (females) ( n = 12).

Ovipositor lobes 2.5 times longer than wide. Figure 6. Adults of Sesamia species. A –D, S. nonagrioides : A, male upper side; B, male under side; C, female upper side; D, female under side. E–H, S. typhae : E, male upper side; F, male under side; G, female upper side; H, female under side. Scale bars = 10 mm.
