Fore wings subfalcate, with a short line in front between the two 
entire lines ; a few slender fawn-coloured streaks, which are mostly 
between the exterior line and the exterior border ; costa with little 
transverse black lines. Hind wings with short tails, which are 
adorned at the base with a deep black red-marked spot and with a 
red black-marked spot, which is bordered by contiguous black 
streaks; second line composed of oblique contiguous brown streaks ; 
some transverse brown streaks along the apical part of the interior 
border as far as the interior line. Length of the body 9 lines ; of
