The stigmata is represented by similar spots, the plical obliquely beyond the first discal, these rather elongate, the second discal rather transverse. There is a triangular spot of dark fuscous suffusion on the costa towards the apex, edged anteriorly by awhite strigula and posteriorly by a white apical spot, and with suffused white subterminal and terminal shades from these crossing the wing.
