prominent on tlie veins. Cilia reddish-coppery. Forewing with the 

 basal half iridescent dark ultramarine-blue visible in all lights, but 

 much brighter in some lights than in others, anteriorly bounded by the 

 subcostal nervure, posteriorly by the inner margin, outwardly reach- 

 ing beyond the discoidal cell, and approaching 'the outer margin at the 

 anal angle. Hindwing with the discal two-thirds blue as in the fore- 

 wing, leaving the costa, outer and abdominal margins about equally 

 broadly fuscous ; anal lobe black, anteriorly bearing a few turquoise- 

 blue scales, inwardly with a small reddish patch. Underside, loth 

 wings as in the male, except that the discal fuscous band is outwardly 

 defined by a whitish thread. 



I possess examples of this sex taken in the Battak Mountains in 

 March and July, and at Bekantschan in March.

Habitat : Battak Mountains, N.-E. Sumatra.

 the second and first median, and all except a small portion exteriorly 

 of the submedian and internal interspaces shining deep brownish- 

 ferruginous of a very unusual shade ; the bases of the three median 

 nervules and that portion of the median nervure between the origins
