Nearest to D. crithoe, Boisdaval, also from Java, but differing in the 

 submarginal series of spots on the forewing being twice as numerous, and 

 all the disco-cellular nervules, instead of the lower one only, defined on 

 each side with a white line ; the hindwing has the white and pale yellow 

 area much larger, thereby reducing the outer black area by one-half. 

 Also near to D. tohahana, Rogenhofer,=Z). derceto, mibi, from Sumatra, 

 but that species lacks the two discal patches of grey scales on the fore- 

 wing, has the white and yellow area on the hindwing smaller, and on 

 the underside has the crimson band of the hindwing at least twice as 

 broad. 



Described from a single example collected by Mr. W. Doherty in 

 Java and given to me by him as a new species. After the description 

 above was written and the specimen figured, I received Herr Fruhstor- 

 fer's description oi B. bromo,* also from Java, from which D. dymas 

 appears to differ mainly in the entire absence of the crimson base to 

 the hindwing on the upperside.

Habitat : Sumatra. 



Expanse : cJ, 5*6 inches. 



Description: Male. Upperside, both ivings rich glossy black. 

 Forewing with some paler streaks in the discoidal cell and between the 

 veins. Hindiving with a large white patch occupying the outer half of 

 the wing, anteriorly bounded by the second subcostal nervule, pos- 

 teriorly extending just beyond the greatly curved first median nervule, 

 not reaching the outer margin, this latter bearing four large conjoined 

 lunular black spots ; the white area bears outwardly four large round 

 black spots, the three anterior ones equal-sized, the posterior one 

 smaller ; the white area between these last-mentioned four spots and 

 the four black lunular spots on the margin sprinkled with black 

 scales ; the abdominal margin is as usual twice folded over, and is 

 lined within with a white flocculent substance, the edge of the fold 

 within being rose-pink. Underside, foreiviug paler than on the upper- 

 side. Sindwing as above, except that the white area has no black 

 sprinkling, and that there is a small white spot at the posterior end of the 

 cell, with three similar ones in the first subcostal interspace, these latter
