Aola, Guadalcanar I. N.W. Bay, Malaita I. Fauro I. Ru- 

 biana I. Ulaua I. 



This species can be immediately distinguished from the preced- 

 ing by its having an additional band in the centre of the cell below, 

 which is also continued downwards nearly to the inner margin. 



Nacaduba korene, sp. n. (Plate XXXI. fig. 8.) 



Male. Allied to N. euretes, but all the bands on underside narrower, 

 and bordered outwardly with sordid white, not pure white as in 

 that species. The submarginal row of lunules is only sligbtly darker 

 than other parts of wings. Expanse srme as N. euretes. 



Aola, Guadalcanar I. Opposite Ugi, San Christoval I. 



This form may prove to be a variety of the preceding, but in 

 a long series of specimens there do not appear to be any inter- 

 mediates. 



Nacaduba amaura, sp. n. (Plate XXXI. fig. 10.) 



Male. Allied to N. ancyra, Felder, from Amboina and Aru, from 

 which it principally differs by having the bands on the underside 

 much more irregular, and by the submarginal row of crescent-shaped 

 lunules being large and dark, and by the greater preponderance of 

 white in the ground-colour, and by being grey in place of brown. 



Female. Upperside dull greyish brown, the disk of the fore wing 

 suffused with blue ; hind wing slightly bluish, with a distinct marginal 

 row of grey-bordered lunules, that one between the median nervules 

 being darker and bordered inwardly with orange. Underside browner 

 than in male, and more strongly diffused with white. 



A short black tail white-tipped, and white below. 



Expanse, S If inch, 5 lyLinch. 



Alu I., near Shortland I. Rubiana I. Malaita I. 



This may prove to be a variety of iV. ancyra, Feld., as it is some- 

 what variable, but amongst the specimens before me are none which 

 agree well with it. 



Nacaduba maniana, sp. n. (Plate XXXI. fig. 9.) 



Male. Allied to the preceding, but a darker shade of blue on 

 the upperside. Underside with all bands bordered with sordid 

 white, having altogether a much duller appearance, and with the 

 marginal row of lunules in the fore wing entirely gone, and the sub- 

 marginal very indistinct. Expanse 1^ inch. 



Ulaua I. 



Several specimens not showing any variation. 



Nacaduba ligamenta, sp. n. (Plate XXXI. figs, lid', 12 5 .) 



Male. Upperside shining violaceous blue ; cilia brown. Underside 

 with light brown bands, bordered with pure white on a greyish- 

 white ground. Primaries with a band in the middle of the cell, 

 another at the end, and beyond that, reaching from the costa to 

 the submedian nervure, a rather narrow macular band ; a marginal
