Cirrochroa thais, also known as the Tamil yeoman,[1][2] is a species of nymphalid butterfly found in forested areas of tropical Sri Lanka and India.

Forewing with a slender dusky-lined discocellular streak, a transverse discal more or less prominent black sinuous interrupted line, its anterior portions from upper median dilated and bent inward; two submarginal sinuous lines, the inner dilating broadly inward to the costa, the outer partly merged into the black of outer border.

Ground-colour of various shades of reddish-ochreous washed with pale violaceous-grey; subbasal line dusky brown; transverse discal band white or violaceous-grey, dilated anteriorly, its inner-edge brown-lined and more or less deeply sinuous or broken up into dentate portions, its outer-edge being straight and unlined; followed by an outer-discal series of very obscure dusky dentate marks on the forewing, and a row of small black spots on hindwing, and submarginal lunular lines of the ground-colour bordered by violaceous-grey.

Underside paler and a duller reddish-ochreous, the subbasal and outer markings obscure, the discal band on both wings entire throughout its course, and either of the same shade as the ground-colour or white, its inner edge being very slightly sinuous, and not broken up into dentate portions as in wet-season form.

Underside paler greyish-ochreous than in wet-season form; subbasal and outer markings similar; the discal baud entire, as in male, white.Wingspan 60–75 mm.
