Show 1896.] MR. H. H. DRUCE ON BORNEAN LYCiENIDJE. 657 Icata, de Niceville1, 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 OSIAS, Ebber. Banguey I., N . Borneo (Waterstr.). L. oslas certainly occurs in Sumatra, although it is not given by Mr. de Niceville and Dr. Martin in their list. W e possess specimens from the N.E. It is closely allied to L. sulclas, 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. sulclas 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. cleodus, 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. oslas correctly. W e possess many specimens of L. oslas, one of which was identified by Herr Bober. LAMPIDES LIVIDUS, 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. THYSONOTIS, Hiibn. THYSONOTIS SCHAEFFERA, Esch. W e have lately received specimens of this species captured at Sandakan. A R H O P A L A , 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 m e 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. B. Through the kindness of M r . 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 m y possession, kindly lent m e by Dr. Staudinger and Herr Georg Semper, show that there is plenty of work yet to be L. marakata, de Nicev.
