254 L. de Nice>ille — List of the Butterflies of the Ke Isles. [No. 2, 



coloured animals, being more or less pure white on the upperside in 

 both sexes, and are mimicked by the females of two peculiar species of 

 Hypolimnas (H. polymeria, Felder, and H. hewitsoni, Wallace). H. M. S. 

 "Challenger" in her memorable scientific expedition round the world, 

 called at Ke Dulan, and Dr. A. G. Butler, in Ann. and Mag. of Nat. 

 Hist., fifth series, vol. xiii, p. 188 (1884), enumerates thirteen species 

 of Butterflies from thence obtained on that occasion, all of which are 

 noted below. The late Herr C. Ribbe in his paper on the Butterflies 

 of Great Ceram (Iris, vol. ii, p. 187 (1889), mentions many species 

 from the Ke Isles, all of which are referred to herein. Herr J. Rober 

 of Dresden in Tijd. voor Ent., vol. xxxiv, pp. 261-334 (1891), vol. xxxv, 

 pp. 85, 86, pis. iii-vi (1892), has written a most interesting paper on 

 the Lepidoptera of the group of Malayan islands which include Ceram, 

 Goram, Maumerie, Key, Flores, Letti, Alor, Luang, Bonerate, Timor, 

 Timor Laut, Kisser, Wetter, and Tanah Djampea, recording 42 (not 41 

 as stated at page 262) species from the Ke Archipelago. All these are 

 mentioned below, and those not seen by us have a * prefixed to their 

 names. The present paper is based on materials obtained by Kuhn 

 during the nine years (from 1889) he has resided on the islands, and 

 he has written the introduction and notes on the habits of the various 

 species, while de Niceville is responsible for the rest of the paper, and 

 has seen it through the press. It is probable that the list is fairly 

 complete, there are probably only a very few small species left to be 

 recorded. We record 128 species from the Archipelago, out of which 

 we have not seen only 17 ; of these latter most of the names are doubt- 

 less incorrect identifications, and appear in our list under other names. 



Family NYMPHALID^]. 

 Subfamily Danain^. 



1. Hestia (Nectaria) d'urvillei, Boisduval. 



In Great Ke this species is usually seen flying in the forest at a 

 great height amongst the trees. It is very rare in Little Ke. 



2. Danais (Tirumala) hamata, Macleay. 



Very seldom seen in Little and Great Ke, common on Koer Isle. 

 De Niceville finds it difficult to distinguish D. septentrionis, Butler, 

 from this species. Macleay's species is much the older. 



3. Danais (Limnas) petilia, Stoll. 



Key, Rober, as Danaus chrysippus, Linnaeus. The Ke Isles examples 

 agree with those from Australia. It is very rare on all the islands.
