 first on costa and subcostal vein, second on either side of the median, third on 

 submedian and inner margin ; fourth row postmedian, outcurved round cell, the 

 curved part formed of six irregular-sized and confluent spots, with three spots below, 

 OQe on the first median nervule and two confluent ou submedian and inner margin ;

Forerrings: with liasal and marginal areas brown-black, central area whit r ; the 

 black at the base extends to beyond middle of costa and nearly to middle of inner 

 margin, its edge sinuous ; its outer edge starts from three-fourths of co.sta, runs first 

 obliquely outward, then \ertical, again obliquely inward, and vertical to inner margin 

 at three-fourtlis on one wing ; on the other oblifjuely inwards to inner margin at two- 

 thirds, so that the white fasciae of the two wings do not correspond in shape ; the dark 

 margin contains a hook-shaped yellow spot below apex \vith a small yellow dot below 

 it and two diamond-sliaped yellow ^pots above anal angle; these spot?, lie in the
