(? ? . Forewing sliarply divided into a jiale basal and a darker distal area, the 

 line of separation running straight across the wing, beginning at costal margin just 

 ])roximally of upper angle of cell and reaching hinder margin several millimetres 

 l)roximally of angle : antemedian and discal lines vestigial, the former curved, the 

 latter almost straiglit, little curved costad in front. Head and thorax with a dark 

 mesial line. 



cJ. Tenth tergite slightly dilated at end, truncate, angles rounded ; stcrnite 

 incrassate at end, apical edge curving upwards, mesially acuminate, upjierside 

 transversely carinate, mesial line elevate. Clasper ivith frictiou-scales ; harpe 

 ending in a very short triangular pointed process (PI. L. f. 30). Process of 

 penis-sheath long and slender (PI. LVI. f. .10), directed proximad, lying close 

 along the sheath, not denticulate, armed with a single long basal tooth which 

 projects distad ; internal rods rounded at end, longer one dilated into a kind of 

 tooth.

S ?. Drury's figure is rather misleading : it is far too large, the expanse being 

 correctly given in the description as only 2 inches, and has three conspicuous yellow 

 spots on the abdomen instead of two, as described. The dark basal area of the 

 forewing and the pattern of the outer half of the same wing as indicated in the 

 figure apply only to the ]>resent species, not to p>/h'iie, with which pas.mlu.i has 

 often been confounded. 



Head and thorax mouse-grey, a dark mesial stripe and posterior half of 

 mesothor.icic tegula dark slate-colour, edge of tegnla and metanotum russet, 

 greenish in certain lights ; yellow side-spot of second abdominal segment small, 

 of third and fourth larger, with conspicuous black spots at the proximal side, sixth 

 tergite almost black, seventh with conspicuous black mesial patch, proximal side- 

 tufts with white tips, those of sixth and seventh segments tipped with yellow or 

 tawny ; abdomen below chestnut-hazel, side of breast and legs nearly the same, 

 middle of breast and anterior tarsus clayish buff. 



Wings, abore. Forewing : basal area up to first antemedian line rather 



darker than head, interspace between the slightly curved first and the straight 

 second antemedian lines filled in with black, the two lines as such just vestigial :
