apex broadly black, this colour extending decreasingly along the 

 costa till it meets the white area, also decreasingly along the outer 

 margin, ending almost in a point at the anal angle. Hindwing with 

 the basal half of the costa broadly white, the apex equally broadly 

 blackj the outer margin bearing a fine black anteciliary thread, 

 defined inwardly by an equally fine white thread ; an indistinct 

 marginal round diffused black spot in the first median interspace ; 

 the anal lobe black, bearing anteriorly a small orange spot ; abdominal 

 margin broadly white. Underside, both loings as in the male, except 

 that the orange spot at the base of the costa of the foreioing is 

 less prominent than in the male, and the orange subanal area on the 

 hindwing is more extensive, extending uninterruptedly to the abdomi- 

 nal margin, and reaching the discal line. 



Described from a single example in my collection captured in 

 March. 



Genus CREUSA* nov. 



Male. Fokewing, triangular ; costa regularly but slightly 

 arched ; apex acute ; outer margin nearly straight ; inner angle 

 rounded ; inner margin nearly straight, slightly emarginate in the 

 middle ; costal nervure ending opposite to the apex of the discoidal 

 cell ; first subcostal nervule arising a little nearer to the apex of the 

 cell than to the base of the wing, close to its base anteriorly bowed 

 forwards, and almost touching the costal nervure for some little 

 distance ; second subcostal arising about as far from the first subcostal 

 as from the origin of the upper disco-cellular nervule ; third 

 subcostal short, arising much nearer to the apex of the wing than to 

 the apex of the cell ; subcostal nervure ending at the apex of the 

 wing ; upper disco-cellular nervule (this is actually the base of the 

 upper discoidal nervule) stout, rather long, strongly outwardly 

 oblique; middle disco-cellular straight, upright ; lower disco-cellular 

 also straight and upright, slightly longer than the middle disco- 

 cellular ; second median nervule arising well before the lower end of the 

 cell; first median arising nearer the lower end of the cell than to the 

 base of the wing, arising about twice as far from the second as the 

 second does from the third ; suhmedian nervure slightly sinuous ; 

 secondary sexual character consists of a large patch of modified deep 

 black scales occupying nearly the outer half of the cell, and extending
