1897.] L. de Niceville— List of the Butterflies of Bali, fye. 669 



the names of all the species recorded from the islands dealt with. This 

 paper is mainly based on the collections made by Mr. William Doherty 

 in Bali, Lombok, Sambawa and Sumba in Elwes' possession, while Herr 

 H. Fruhstorfer has kindly sent de Niceville some seventy-nine species 

 collected by himself in Lombok. All species recorded from any of the 

 islands taken together considered herein not seen from any one of them 

 by the writers are indicated by an asterisk (*) prefixed to their names. 

 The number of species recorded from each island in this paper is as 

 follows : — 



Bali, 201. 

 Lombok, 189. 



Sambawa, 181. 

 Sumba, 158. 



These numbers are remarkably even, but they shew a steady 

 diminution as one proceeds from west to east. Java has at least 500 

 distinct species of butterflies, Sumatra still more. 



Mr. Doherty records about 135 species from Sambawa, several of 

 which, however, he could not name as he had lost the specimens. For 

 instance, at the end of his paper he writes : " My Sumbanese TIesperiadte 

 have suffered more than any other family, and I have been compelled to 

 omit a number of species, a Halpe, two Parnaras, a Parata, etc." On 

 page 157 of his paper he says he obtained about 140 species from 

 Sambawa and Sumba. 



Mr. Doherty numbered the species he obtained from Sumba, the 

 total being 130, but of these one species, Stictoploea lacordairei, Moore, 

 was inadvertently entered as from Sumba, while it really was obtained, 

 in Sambawa. In counting up the number of species he mentions, the 

 total is 140 (omitting the Euploea), so that there were eleven species he 

 was unable to name for want of specimens when writing his paper. 



Dr. Pagenstecher in his first paper on the butterflies of Sumba 

 records 34 species only as received by him, but several of these are not 

 included in Mr. Doherty's list. 



Dr. Pagenstecher in his second paper records 57 species from 

 Sambawa, and 88 species from Sumba, many of these being new records. 

 His total from both islands is 110 species. 



Mr. Fruhstorfer names 176 species from Lombok, and a " Narathura" 

 and two ArrJwpalas are unnamed, a total of 179 species. 



Mr. Fruhstorfer gives 28 species from Bali, of which he described 

 three as new. 



Between the islands of Bali and Lombok is found the deep depres- 

 sion in the sea-floor which is generally known as " Wallace's Line," and 

 is supposed to faunistically divide the Indo-Malayan and Austro- 

 Malayan regions. In the three islands of Lombok, Sambawa and 

 Sumba dealt with in this paper which lie to the east of this line, there
