Drepana acuminata, sp. n. 



<? . Pale reddish brown ; apex of primaries blackish, much produced 

 and acutely pointed ; two dark brown lines traverse the disc of the wing, the 

 first is deflected to median nervure, then inflected to inner margin, the 

 second runs from costa towards outer margin as far as first discoidal 

 nervule, where it joins a darker apical streak, then turns inwards 

 and descends obliquely to inner margin ; an obscure submarginal line ; 

 two small black central spots. Secondaries have two central dark brown 

 lines, the first curved and the second straight ; submarginal line slightly 

 wavy, also dark brown. Under surface whitish, tinged with brown 

 over costal area of primaries, one central black spot ; a dark brown line 

 traverses the wing from near blackish apex to inner margin ; submarginal 

 line obscure ; secondaries have a central black spot and dark brown trans- 

 verse line ; submarginal line also dark brown, but very faint. Expanse,

One male specimen taken in July at Ichang.

 before inner margin ; purplish black, outer margin bordered with tawny, 

 interrupted by a line and cloud of the ground colour and preceded by a 

 broad whitish band. Secondaries similar to primaries, but rather paler and
