[Eeceived June 14, 1895.] 



(Plates XXXI.-XXXIV.) 



Since my father, Mr. Herbert Druce, pubhshed, in the Pro- 

 ceedings of this Society for 1873, a list of Bornean butterflies 

 obtained by Mr. (now Sir Hugh) Low in the neighbourhood of 

 Labuan, very httle has been written on the subject at aU and scarcely 

 any additions have been made to om* knowledge of the Lyccenidce. 

 Messrs. Distant and Pryer have described a few, obtained at Sanda- 

 kan by Mr. Pryer, in the ' Annals and Magazine of Natural History ' 

 (ser. 5) vol. xix. 1887, as also has Mr. Grose Smith in vol. iii. 

 (ser. 6), 1889, of the same periodical ; whilst Mr. de Niceville has 

 mentioned some species as occurring in Borneo in his work on the 

 Butterflies of India, Burmah, and Ceylon, and has described one 

 or two in the Journal of the Bombay JVatural History Society, 

 1891. In the Journal of the Asiatic Society of Bengal, vol. Ix. 



1891, Mr. W. Doherty has recorded a few species, and described 

 a new one of the genus Nacadvha, and Dr. Butler, in an account 

 of a collection of Lepidoptera obtained by Mr. W. B. Pryer at 

 Sandakan pubhshed in the Proceedings of this Society (P. Z. S. 



1892, p. 121), has described a single species of the genus Arlwpala. 

 These papers, with the addition of one or two solitary descriptions, 

 are all that I can discover as referring to the Lyccenidce of the 

 region dealt with here. 



The large amount of material which I have worked upon for this 

 paper is partly contained in Messrs. Godman and Salvin's collection, 

 and my thanks are due to those gentlemen for kindly allowing me 

 free use of their fine series, and also to Dr. Staudinger, to whom I 

 am also much indebted for the opportunity of examining the whole 

 of the specimens collected on Kina Balu by Waterstradt and at 

 Labuan by Wahnes. This collection from Kina Balu, containing as 

 it does examples of a large number of new species, I have found of 

 the greatest importance ; and to those interested in the geographical 

 and other features of this great mountain I would recommend a 

 perusal of Mr. J. Whitehead's book, 'The Exploration of Kina 

 Balu, IS". Borneo.' Besides these collections, we have in our own 

 possession a considerable number of specimens from Kina Balu, 

 Elopura, Sarawak, and Sandakan. 



Dr. Staudinger informs me that the species labelled " Labuan," 

 captured by Waterstradt and "Wahnes, are not from the smaU 

 island on the N.W. coast but from the mainland opposite. 



Mr. Herbert Druce recorded 71 species of the family in his list, 

 and this number I am now able to increase to about 220, inclusive 

 of about a dozen species of the genus Arliopcda which are either 

 undetermined or unnamed. Mr. de Niceville enumerates 402 

 species in ' The Butterflies of India etc.,' so that we have already
