Male and female : forewing violet greyish-brown ; crossed by a pale-bordered 

 black subbasal short line, an inwardly-curved antemedial line, followed by a pale- 

 bordered deep brown broad discal band, which is curved on its inner edge and 

 triangulated on its outer edge, and from its upper angle extends a recurved subapical 

 deep brown streak, the costal edge above it being marked by pale dots ; below the 

 streak is a submarginal series of more or less distinct black points, each point ending 

 in a white-speckled streak along the veins, the black points being most distinct on 



• Ochsenheimer divided his genus Ophiusa into three sections : A, b, c. Hiibner in 1818-25 (Verz. 

 p. 267), and Stephens in 1830 (lUust. iii. p. 125), used it for section A qxi\y = {Toxocampa, of Guenee in 

 1852). This action of Hiibner's and Stephens' consequently restricted the genus Ophiusa to the species 

 of section a.
