A LIST OF THE BUTTERFLIES OF BORNEO. 75 
and taking in Mt. Kina Balu, through Lawas, Limbang, Brunei 
to the western limit of Sarawak territory: then south through 
Sambas, and Pontianak and so along the South coast to Bandjer- 
masin and Pulo Laut where Mr. Doherty collected many species.’ 
It is proposed to follow Mr. Shelford’s original idea of resery- 
ing a discussion on the geographical distribution of Bornean Butter- 
flies for an Appendix, to be added after the completion of the 
whole list. However, it will not be out of place to give here the 
following figures, which indicate some of the principal features of 
the distribution of Bornean Lycaenidae. 
Out of the 300 species recorded, no Jess than 117 are at present 
confined to Borneo as far as we know. Of the remainder, 120 are 
common to Borneo and the Malay Peninsula (Burma to Singapore), 
98 to Borneo and Sumatra, and 47 to Borneo and Java. The com- 
paratively small relationship with the Philippines, Celebes and New 
Guinea (including Australia) is shown by the occurrence of 41, 13 
and 14 Bornean species respectively in those countries.” 
Due regard has been paid to the importance of recording any 
variations in all the forms, and the Sarawak Museum collection 
has been carefully examined for this purpose. 
The following new species are now described for the first 
time. Those marked with an asterisk indicate that they were 
noted as new by Mr. Shelford, but not described, and I have re- 
tained his names for those species. 
270. Allotinus strigatus 402. Arhopala incerta 
272. Allotinus borneensis 428. Arhopala sarawaca 
"498. Charana? abnormeis 432. Arhopala tembaga 
289. Logania drucei 451. Arhopala shelfordi 
298. Neopithecops oskewa 452. Arhopala rajah 
314. Lycaenopsis lingga 474. Tajuria sunta 
*3515. Lycaenopsis nigerrimus 486, Chiiaria balua 
318. Lycaenopsis delapra = 497. Charana sple ndida 
*354. Lampides vyneri *498. Charana? abnormis 
*381. Poritia pastra 506. Horaga albistigmata 
Some of the Bornean Lycaenidae have been described from one 
sex only, and I am able to furnish descriptions of the hitherto- 
unknown sex of the following species :— 
311. Lycaenopsis sonchus, H. H. Druce, 2 
316. Lycaenopsis moultoni, Chapman, @ 
326. Nacaduba lugine, Druce, 2 
327. Nacaduba angusta, Druce, 2 
d41. Lampides virgulatus, H. H. Druce, @ 
379. Poritia philura, H. H. Druce, 9 
1. Fora lucid and concise description of Sarawak localities see Shelford in 
Straits Branch, Roy. As. Soc. Journ. No. 35, p. 44, 1901. 
2. Owing to our incomplete and uneven knowledge of the Butterfly Fauna of 
these countries these figures are necessarily inaccurate to a certain degree, but 
they serve to indicate the lines of relationship and to corroborate the conclusions 
arrived at by other writers on the various branches of the Bornean Fauna.
