margin tn liinder margin, which it, reaches not far from angle, divides the wing as m 

 liemichroma , but the line of division is less sharp and the outer half of the wing is 

 mnch shaded with grey, the two halves not contrasting so sharply as in hemichroma ; 

 a trapcziform snbapical costal patch C — K' and a distal marginal baud not grey.

cJ ? . Forewing sharply divided into a pale basal and a darker distal area, the 

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

 proximally of npper angle of cell and reaching hinder margin several millimetres 

 proximally of angle ; antemedian and dlscal lines vestigial, the former curved, the 

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

 mesial line. 



S. Tenth tergite slightly dilated at end, truncate, angles rounded ; stcruite 

 incrassate at end, apical edge curving upwards, mesially acuminate, upi)erside 

 transversely carinate, mesial line elevate. Clasjjer with friction-scales ; harpe 

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

 peuis-sheath long and slender (PI. LVI. f. 50), directed proximad, lyiug close 

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

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

 tooth.

6 ? . Drnry's figure is rather misle.iding : it is far too large, tlie 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 present species, not to pi/lciie, with which pa.'i.'t<ih(x has 

 often lieen confounded. 



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

 mesothoracic tegnla dark slate-colour, edge of tegula and metanotum russet, 

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

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

 tergite almost black, seventh with consjiicuous black mesial ])atch, proxinnil side- 

 tnfts with white tips, those of sixth and seventh segments tij)i)ed with yellow or 

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

 middle of breast and anterior tarsus olayish buff. 



Wings, ahorr. Forewing ; basal area up to first antemedian line rather 



darker than head, inters]iaec between the slightly curved first and the stniight 

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