Kina Balu (Waterstr.) ; Labuan {Low). 



I have no hesitation in placing P. lacturnus, Godt., as a synonym 

 of E. arr/iades after examining specimens from Timor. The species 

 is also a very common one in New Guinea, where the females 

 are sometimes pale grey with darker borders, and where it varies 

 much in size, one male in Messrs. Godnian and Salvin's collection 

 measuring only slightly more than g inch.

 Specimens from Kina Balu are darker on both surfaces than 

 those from the other localities. 



Nacaduba LtJGiNE, sp. n. (Plate XXXII. fig. 15 d" .) 



Cupido pactolus, Druce, P. Z. S. 1873, p. 348 (nee Eeld.). 



(J . Allied to iV. macrophthalma, Eeld. ; rather larger. Upper- 

 side brighter and more violaceous blue, and with scarcely any 

 silvery gloss. Underside pale rufous brown, with the fasciae 

 narrower, paler, and in the fore wing much more irregularly broken, 

 so that there is no distinct Y- The black spot between the lower 

 median nervules is larger and more broadly edged with rich dark 

 orange. 



Expanse If inch. 



Labuan (Low). Type Mus. G. & S. 



On comparing this species with the type of L. pactolus, Eeld., 

 to which it was referred by Mr. Herbert Druce iu his paper on 

 Bornean Butterflies, I find that it is quite distinct, and, as I can 

 lind nothing else like it, am compelled to describe it as new. 



Messrs. Godman aud Salvin's collection contains another small 

 female specimen of a species belonging to this group, which on the 

 upperside resembles that sex of N. atrata, Horsf., and on the 

 underside is much bke N. ixtvana, Horsf., but until the male is 

 discovered I do not care to pi'opose a name for it. It expands 

 lyijp inch and is from Sandakan. 



Nacaduba angusta. 



Cupido antjusta, Druce, P. Z. S. 1873, p. 349, pi. xxxii. fig. 9. 



Labuan {Low). 



Messrs. Godman and Salvin's collection contains the type of 

 this species. The figure given is quite useless and misleading and 

 hardly bears any resemblance to the insect. In it the wings 

 appear to be dark grey with yellow borders and black markings
