and a darker distal area, the line of separation running straight 

 across the wing, beginning at costal margin just proximally 

 of upper angle of cell and reaching hind margin several 

 milhmetres proximalh 7 of angle ; antemedian and discal lines 

 vestigial, the former curved, the latter almost straight, little 

 curved costad in front. Head and thorax with a dark mesial 

 line. Expanse : 2 70 mm. (one example). 



$. Tenth tergite slightly dilated at end, truncate, angles 

 rounded ; sternite incrassate at end, apical edge curving 

 upwards, mesially acuminate, upperside transversely carinate, 

 mesial line elevate. Clasper with friction-scales ; harpe (fig. 91 M) 

 ending in a very short triangular pointed process. Process 

 of penis-sheath (fig. 91 N) long and slender, 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.

Imago. — ^$. Head and thorax mouse-grey, a dark mesial 

 stripe and posterior half of mesothoracic tegula 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 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. Fore wing : basal area up to first ante- 

 median line rather darker than head, interspace between 

 the slightly curved first and the straight second antemedian 

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

 median interspace more or less russet, palest at antemedian 

 band ; first discal fine thin, more or less vestigial, second heavier , 

 both curved costad in front, with the upper part of the inter- 

 space filled in with brown, often a vestige of another line between 

 the two ; second fine joined behind R 1 to subapical spot 

 SC^-R 1 and apical half-moon, a broadish black cloud from 

 R 1 towards outer margin near angle. Yellow band of hind 

 wing concave distally, the black border of wing almost evenly
