two species are really one. It is very common on nearly all the islands 

 of the Ke group, but it seems rare on Koer. Mr. Kiihn has bred it. 

 The larva is black ; each segment bears several yellow stripes, the first 

 of which extends lower than the others and encloses the black spiracle. 

 The head, abdomen and legs are entirely black. The body bears 

 four pairs of long fleshy subdorsal tentacles tapering to a point, each 

 is basally carmine-red, becoming black towards the apex, the first pair 

 is placed between segments two and three, the second between three 

 and four, the third between four and five, the fourth between ten and 

 eleven. The pupa is greenish and metallic. 



The Euploeas of the Ke Archipelago are very interesting, and form 

 four distinct groups as regards coloration and markings : — I, E. eurypon, 

 Hewitson, E. hopfferi, Felder, and E. assimilata, Felder, which are 

 mimicked by the females of Hypolimnas polymeria, Felder, and H. hewit- 

 soni, Wallace ; II, E. sacerdos, Butler ; III, E. callithoe, Boisduval ; IV, 

 E. visinda, Butler. 



Subfamily Satyrinj:. 



14. Mtcalesis (Calysisme) persetts, Fabricius. 



Occurs on Great and Little Ke in fields of " alang-alang" grass, 

 but is not common. The ocellated wet-season form appears to be the 

 only one found on the islands. In both sexes the ocellus in the first 

 median interspace of the forewing on the upperside has a small pure 

 white pupil. 



15. Mycalesis (Mydosama) sirius, Fabricius. 



Little and Great Ke Isles. Much rarer than the preceding species. 

 *' Satyrus " manipa, Boisduval, and Mycalesis daidis, Hewitson, are 

 synonyms. 



16. Ypthima arctous, Fabricius. 



Rober. Occurs commonly everywhere on all the islands, and fre- 

 quents meadows. 



17. Hipio constantia, Cramer. 



Rober and Ribbe as Melanitis crameri, Butler, described from New 

 Britain, equals " Cyllo " amabilis, Boisduval, from New Ireland. The 

 type of the genus Hipio of Hiibner is the present species. It is doubt- 

 fully distinct from the genus Melanitis, Fabricius. H. constantia is 

 rather rare in all the islands, keeping chiefly to bamboo and sago scrub. 

 Colonel Swinhoe has described a single male of this species from " Ke
