Show 360 MR. H. H. DRUCE ON THE [June 2, distinct spots. • Supposing, as I do, that the median nervule is continued to the margin, there is a large deep black spot narrowly bordered inwardly with pale orange, and outwardly with brilliant metallic light blue, between the first and second branches ; also a lengthened black spot at the anal angle thickly covered with blue scales, and bordered inwardly with a minute orange spot, which, however, is not always present. Female. Dull blackish brown. Primaries of a lighter and more brilliant violaceous blue in the discal area, and the costal and outer margins evenly and broadly bordered. Secondaries with a few blue scales scattered over the surface, and a marginal row of large black lunules, largest towards the anal angle, very narrowly bordered with greyish blue. Underside as in male. Head, thorax, and abdomen concolorous with wings : antennae black above, spotted with white beneath. Expanse, 6 2 'TJT"'T% incn- This species has a short black tail with a white tip on the lower median nervule. Guadalcanar I. Tyoh, Malaita I. Ulaua I. The blue on the females from Ulaua I. has almost entirely disappeared, and in specimens both from Malaita I. and Ulaua I. the orange near the anal angle on underside of hind wings is replaced by white. The markings on the underside, although arranged much as in N. macrophthalma, are much more distinct than in that species. It is also a smaller insect. NACADUBA UGIENSIS, sp. n. (Plate XXXI. fig. 5.) Female. Allied to N. plumbata. Disks of upper surface suffused with a lighter and more brilliant bine. Underside much paler, and with bases of both wings much more strongly suffused with light bluish-emerald-green. Expanse same as N. plumbata. Ugi I. (Mathew). Messrs. Godman and Salvin's collection contains three specimens obtained by Mr. Mathew, but Mr. Woodford does not seem to have met with any. The pale colour and strong suffusion of green on the underside gives the species a remarkable appearance. NACADUBA EURETES, sp. n. (Plate XXXI. figs. 6 c?, 7 2 •) Male. Allied to jV. prominens, Moore. Upperside much more brilliant violaceous silvery-blue, with the brown margins broader. Underside with markings much as in N. prominens, but the sub-marginal row of lunules on both wings very large, triangular, and much darker than the bands. Female. Dark greyish brown, with the disk of the primaries brilliantly suffused with light blue. Head, thorax, and abdomen concolorous with body. A short brown tail tipped with whitish.
