Tcata, de Niceville ', but on the underside is quite different and 

 appears to belong to another group. I have not seen L. mara- 

 Jcata, and can only judge from the description. Mr. Cator 

 captured L. daones in December. 



Lampides osias, Eijber. 



Banguey I., N. Borneo (TTato-sfj-.). 



L. osias certainly occurs in Sumatra, although it is not given by 

 Mr. de Niceville and Dr. Martin in their list. We possess speci- 

 mens from the N.B. It is closely allied to L. suidas, 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 L. suidas are broader and straighter. 



From some remarks made by Mr. de Niceville in the Journ. 

 Bomb. Nat. Hist. Soc. vol. x. p. 38 (1895), it is evident that he has 

 not seen the type of L. deodus, Feld., as he writes of it as " azure- 

 blue." It is paler than L. 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 L. osias, one of which was iden- 

 tified by Herr Eober. 



Lampides lividus, H. H. Druce. 



ffina 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. 



Thxsonotis, Hiibn. 

 Thtsonotis sohabffbba, Esch. 



We have lately received specimens of this species captured at 

 Sandakan. 



Abhopala, Boisd. 



Mr. Gr. T. Bethune-Baker, who has been working at this genus 

 for some three years, has prepared the following addititmal 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. Bethuue-Baker 

 is entirely responsible for all the new species of this genus here 

 described.— IT. 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 nevi^, and these, together with a number of 

 others now in my possession, kindly lent me by Dr. Staudinger and 

 Herr G-eorg Semper, show that there is plenty of work yet to be
