another on middle of hindmargin, and sometimes a larger one on inner 
margin before anal angle, sometimes all partially confluent ; a slender 
cloudy blackish transverse line from costal spot to anal angle, irregularly 
sinuate, and strongly dentate inwards beneath costa: cilia whitish, with 
two cloudy dark grey lines. Hindwings grey, apex and hindmargin 
darker ; cilia grey-whitish, with a faint darker line. 
At once distinguished by the white head and white ground-colour of the 
forewings; in the form of the anterior line it approaches T. spartodeta.
