714 A LIST OF THE BUTTERFLIES OF BORNEO. 
The system of classification followed in the first portion of 
this paper is that laid down by Col. Bingham in his volume on 
Indian Butterflies (/auna of British India Serles, Bulterflies, Vol. 
Il. 1907), which deals with five out of the seven Sub-Families 
occurring in this region. Of the remaining two Sub-Families, I 
have followed Mr. Bethune-Baker’s recent monograph for the 
Arhopalinae (“ A revision of the Amblypodia group of the Family 
Lycaenidae,” Trans. Zool. Soc. Lond. Vol. XVII. pp. 1-153 P1. 
I-V. 1903), and for the Theclinae, in the absence of any more up- 
to-date work, I have endeavoured to follow out the lines of class- 
ification suggested by Mr. de Nicéville in his Butterflies of India,

Mr. Shelford has kindly furnished me with a few field-notes, 
which I have added under his initials; and I am further indebted 
to him for much valuable advice and help received from time to 
time during the compilation of this paper. Dr. T. A. Chapman 
has kindly identified some of the Lycaenopsids for me, a difficult 
group unless one has devoted much study to its various species. 
‘Yo Mr. G. 'T. Bethune-Baker I owe thanks for help with some of 
the Arhopalas. And lastly, it is with much pleasure | take this 
opportunity of recording my indebtedness to Mr. Hamilton H. 
Druce, who has continually placed his valuable services at my 
disposal. Doubtfully identified species have been sent to him on 
and off for the last two vears and without his help many little points 
would have still remained unrayelled. The Superintendent of the 
Indian Museum has kindly supplied details of the Bornean Lycae- 
nidae in the collections of that Museum. 
Although the general system laid down by Mr. Shelford for 
Parts I and II, has been followed for this Part, I have considered 
it advisable to amplify it on one or two points. ‘Thus in quoting the 
literature for each species I have given the reference to the original 
description first, then the name and reference of any species “that 
has been proved synonymous; in cases where the original description 
being for one sex only, the other sex has been described elsewhere, 
J have given both references. 
As Borneo is the third largest island in the world, it would 
seem superfluous to remark on the yagueness of “ Borneo” as a 
habitat for any species, although this has sufficed for many writers 
on the different branches of the Fauna of Borneo. However, care 
has been taken in this paper to give as many e.act localities as 
possible; so that by this means some traces of relationship may be 
indicated between the fauna of different parts of Borneo and the 
surrounding countries, and between the mountain fauna of Borneo 
and that, for instance, of Upper Burma and the Himalayas. The 
majority of localities are taken from the fine collection in the 
Sarawak Museum, and for that reason many of those names are of 
places in Sarawak. The same geographical order of names is 
always adhered to, viz. starting from Sandakan on the North-East 
coast, going round to the North of the island, then south-westwards
