apical patch on the anterior wings, a little paler, and a 

 broad submarginal band on the hind-wings nearly white. 

 Beneath; as in the female, but paler. 



Hab. — Amboyna, Ceram, Bouru. (Wallace). 



Prof. Westwood supposed a glossy-blue insect from 

 Java, of exactly the same form as the above, to be the 

 male of Cramer's Antilope, and he is followed by Mr. 

 Moore in the Catalogue of the Lepidoptera of the East 

 India Company. I have ascertained, however, that these 

 are females, and constitute one or more distinct species, 

 peculiar to the western part of the Archipelago.

Male. Form of D. Antilope, rather smaller. 



Above; bronzy or olive-brown, with a blue gloss on the 

 costal and outer margins of the anterior wings, and the 

 outer part of the hind-wings paler. A row of white 

 round spots parallel to the outer margin as in D. Antilope, 

 but larger and more distinct; a band of three white or 

 bluish-white marks, sometimes very indistinct, across the 

 anterior wings beyond the middle; marginal and sub- 

 marginal spots as in D. Antilope. Beneath ; olive-brown, 

 spots and markings as above, with one additional white 

 spot on the costal margin. 



Female. Above; rich purple-brown, the whole surface 

 of the upper-wings, except the basal third, richly glossed 

 with satiny blue, a transverse band of three blueish elon- 

 gate spots beyond the cell, and a fourth much smaller; 

 the two white spots of the intra-marginal band nearest 

 the costa large and confluent, while those nearest the anal 

 angle are small and indistinct. Beneath; as in the male. 



Hab. — Malacca {^); Java (?) (Wallace). 



Local form. 



Male. Like D. anomala, but the two apical white spots 

 are larger, and there is a broad submarginal whitish band 

 on the hind wings, not reaching the outer angle.
