Kina Balu ( Waterstr.). 
Mr. de Nicéville has examined Felder’s type, and states that 
NV. viola, Moore, is a synonym of this species. 
NACADUBA NOREIA. 
Lycena noreia, Feld. Verh. zool.-bot. Ges. 1868, p. 282. 
Labuan ( Wahnes). 
Dr. Staudinger has received the tailless form of WN. ardates, 
Moore, which according to Mr. de Nicéville (he having seen the 
type of Z. noreia at Vienna) equals that species. 
NacaBupa atura, Druce. 
I think it is most probable that the species VV. nanda described by 
Mr. de Nicéville in Journ. Bomb. Nat. Hist. Soc. vol. x. p. 34, pL. 8. 
fig. 23 (1895), is the same as NV. aluta. N. aluia has the prominent 
white anteciliary thread in the three anal interspaces as described 
by Mr. de Nicéville, but on the underside of the fore wing the 
anteciliary line only is straight, the other two lines being lunulated, 
both much to the same extent, the spaces between the lines being 
darker, as described in VY. nanda!. 
LAMPIDES DAONES, sp.n. (Plate XXIX. fig. 5, 3.) 
6. Upperside pale shining silvery blue, appearing of a greenish 
shade in some lights. Fore wing: costal margin very narrowly, 
apex and outer margin broadly, dull black. Hind wing dull 
black, with the blue colour extending just over and around the 
cell only ; inner margin paler ; a marginal row of indistinct black 
lunules edged with sordid white, the one between the lower 
median nervules being large and distinct, followed by a black ante- 
ciliary line. Tail black, tipped with white. Cilia of fore wing 
dull black, of hind wing sordid white, black at the extremities of 
the nervules. Underside pale greyish brown, with white lines 
arranged exactly as in L. elpis, Godt., but in the hind wing rather 
straighter. Thorax and abdomen above and below concolorous 
with wings. Antenne black, spotted with white. 
Expanse 13 inches. 
Penungah. Mus. Cator and Druce. 
On the upperside this butterfly appears to be allied to L. mara- 
1 Mr. de Nicéville states, in the list of Sumatran Butterflies, that he thinks 
N. perusia, Felder, is probably a synonym of N. atrata, Horsf. This is not 
so. We possess specimens from Amboyna which I have compared with the 
type in the Felder collection, On the upperside WV. perusia is much like 
N. atrata, but on the underside is quite different, the white lines, excepting 
those at the bases, are further apart, and have the ground-spaces between them 
white, bordered on each side by a brown line,
