kata, de Nicéville', but on the underside is quite different and 
appears to belong to another group.’ I have not seen L. mara- 
kata, and can only judge from the description. Mr. Cator 
captured L. daones in December. 
LAMPIDES Ostas, Rober. 
Banguey I., N. Borneo ( Waterstr.). 
L. osias certainly occars in Sumatra, although it is not given by 
Mr. de Nicéville and Dr. Martin in their list. We possess speci- 
mens from the N.E. It is closely allied to Z. swidas, Feld., of 
which I have examined the type, but is a paler shade of blue on 
the upperside, and the white markings of the underside show 
through more than usual, especially on the hind wing. On the 
underside the lines of Z. suidas are broader and straighter. 
From some remarks made by Mr. de Nicéville in the Journ. 
Bomb. Nat. Hist. Soc. vol. x. p. 38 (1895), it is evident that he has 
not seen the type of L. clcodus, Feld., as he writes of it as ‘‘ azure- 
blue.” It is paler than LZ. celeno, Cr.,in fact almost white, shining, 
and with a slight greenish tinge; and, from some remarks further 
on, on the same page, I do not feel certain that he has identified 
L. osias correctly. 
We possess many specimens of Z. osias, one of which was iden- 
tified by Herr Rober. 
Lamprprs Livipus, H. H. Druce. 
Kina Balu ( Waterstr.). 
Dr. Staudinger has received a single male specimen of this 
species, which agrees well with the type from Labuan, but is 
slightly stronger in colour on both surfaces. 
Tuysonotis, Hiibn. 
THYSONOTIS SOHABFFERA, Esch. 
We have lately received specimens of this species captured at 
Sandakan. 
ARHOPALA, Boisd. 
Mr. G. T. Bethune-Baker, who has been working at this genus 
for some three years, has prepared the following additional list of 
Bornean species, and has sent me descriptions of those which he 
considers to be new,whilst I have added new localities to some few 
species which I have previously referred to. Mr. Bethune-Baker 
is entirely responsible for all the new species of this genus here 
described.— H. H. D. 
Through the kindness of Mr. H. H. Druce I have recently been 
enabled to examine several specimens of the genus Arhopala 
which are evidently new, and these, together with a number of 
others now in my possession, kindly lent me by Dr. Staudinger and 
Herr Georg Semper, show that there is plenty of work yet to be
