268 L. de Niceville — List of the Butterflies of the Ke Isles. [No. 2, 



63. Nacaduiu ancyra, Felder. 



Found not commonly on all the islands on the flowers of Leguminosse. 



64. Nacaduba perusia, Felder. 



Little Ke Isle, rare, mostly found sitting on the tops of dry bushes. 

 N. laura, Doherty, is very close to N. perusia, if indeed actually separ- 

 able, except perhaps in the female. 



65. Nacaduba atrata, Horsfield. 

 Rather rare on Little Ke Isle. 



66. Nacaduba nora, Felder. 



Little Ke Isle. The tailed form appears alone to occur, and is 

 perhaps better known as N. ardates, Moore. 



67. Jamides purpurata, Grose Smith. 



J. purpurata, Grose Smith, Nov. Zool., vol. i, p. 574, n. 219 (1894). 



Ribbe as Plebejus astraptes, Felder. J", purpurata was originally 

 described from New Guinea. If we have correctly identified theKe Island 

 species the male is distinguished by its bluish-purple colour on the upper- 

 side, which is not nearly as brilliantly metallic as it is in /. bochus, Cramer, 

 and its allies, and the outer black border to both wings is about 1*5 mm. in 

 width. It is near to J. cephion, H. H. Druce, Proc. Zool. Soc. Lond., 

 1891, p. 367, pi. xxxi, fig. 19, male, from the Solomon Isles, but has the 

 black border to both wings on the upperside about twice as broad, and 

 it is not " brilliant morpho blue." It differs from J. astraptes, Felder, 

 as figured by Semper from the Philippines, in having the black border 

 to the forewing on the upperside in the male less broad, and on the hind- 

 wing about twice as broad. In the Ke Isles it is rare, and is found on 

 Little Ke Island only. 



68. Lampides aratus, Cramer. 



Butler, Ribbe and Rober as Lampides setherialis, Bntler, from Ke 

 Dulan {Butler), and Key (Ribbe and Rober). The commonest species 

 of the genus on all the islands of the Ke Archipelago. 



69. Lampides celeno, Cramer. 



Butler as L. selianus, Fabricius, from Ke Dulan, and Rober as 

 Plebeius selianus, from Key. Also very common on all the islands.
