 lower end of cell, the origin of vein 2 only a little inwards ; costa highly arched in the 

 middle, apex angular, outer margin sinuate, somewhat produced and angled at the end 

 of vein 3, slightly concave above the angle, the wing somewhat square in shape. 

 Antenme with a moderately fine club, well hooked, with the tips acuminate ; palpi

■ Imago. — Male. Upperside dark brown, with a purplish tint. Forcu-iiKi with two 

 sub-apical semi-hyaline white dots near the costa, and sometimes a third very minute 

 dot, an indistinct discal fascia a little darker than the ground colour of the wing. The 

 species varies in the shade of colour ; in some examples it is much paler and more 

 brown than in others, showing the discal fascia more plainly. Iliiidwuig also with 

 indications of a discal darker shade of colour, not visible in the darker specimens, a 

 white dot at the end of the cell, absent in some examples. Underside similar but 

 paler. Cilia concolorous with the wings. Antennae with the upper half of the club dull 

 ochreous on the underside, and a whitish streak on the shaft below the club ; head, 

 body above and below and the legs concolorous with the wings. 



Female. Upperside paler and with an ochreous tint. Forewing with three sub- 

 apical spots, more linear and larger than in the male ; a larger spot at the end of the 

 cell, with its inner side extending upwards and with a dot between it and the costa, a 

 spot below it in the middle of the first median interspace and a dot outside, between 

 their outer ends at the base of the second median interspace. Hindtcing with a
