 On the forewing this white patch extends above the cell, the discocellulars closing which are prominently marked by a black tooth, and posteriorly it reaches the dorsal margin.On the hindwing the white patch is very large and in some specimens very diffuse.Both forewings and hindwings are shaded at the base by dusky scales and in many specimens the markings of the underside are plainly visible by transparency; the broad black streak above the cell on the hindwing is present in some, absent in other specimens.
