Show 1891.] LYCiENIDiE OF THE SOLOMON ISLANDS. 359 NACADUBA, Moore. All the species here included in this genus have the first branch of the subcostal nervure completely anastomosed with the costal nervure for a more or less considerable distance, and it would seem that this fact may prove to be of much value in determining closely allied species. For instance, N. felderi, Murray, is stated by Mr. de Niceville (Butt. India &c. iii. p. 147), following Herr Semper, to be a synonym of N. nora, Feld.; but in N. nora (from Sikhim) the first subcostal nervule is anastomosed with the costal nervure for a distance rather less than equal to its length from the subcostal nervure to where it joins the costal nervure, whilst in N. felderi it is anastomosed nearly four times this length. The type of N. nora is from Amboina, and it seems possible that the Indian insect is wrongly identified. NACADUBA ASTARTE. (Plate XXXII. fig. 10 $ .) Lampides astarte, Butl. Ann. Nat. Hist. (5) x. p. 150 (1882). Alu I., near Shortland I. Fauro I. N.W. Bay, Malaita I. Several specimens ($ ) agreeing well with Mr. Butler's type in the British Museum from New Britain. There is a male of what I believe to be this species in Messrs. Godman and Salvin's collection, which on the upperside is a silky brownish blue, and on the underside has the conspicuous white bands somewhat narrower than the type, and also the specimens referred to above. It is from the Duke of York I. The specimen figured is from Fauro I. NACADUBA PLUMBATA, sp. n. (Plate XXXI. figs. 3 J, 4 $ .) Male. Allied to N. macrophthalma, Feld. Upperside dark violaceous blue, with the margin narrowly, and cilia dark blackish brown, the outer margin of primaries more rounded, and in that respect resembling N herms, Feld., from Amboina. Underside light brownish grey, with all the macular markings and lunules slightly darker and bordered outwardly with pure white. The fore wing slightly, and the hind wing extensively, suffused with bright emerald-green scales at the base. Primaries with a rather narrow band at the end of the cell, and beyond that at about halfway between it and the outer margin a continuous unbroken macular band of about equal width as far down as the median nervure, below that gradually widening inwardly to the submedian nervure; beyond this band a submarginal row of darker crescent-shaped lunules enclosing a marginal row of large indistinct spots. Secondaries with a basal band, broadest on the costa, another near the end of the cell, and beyond that, commencing rather beyond the middle of the costa, a very irregular much-broken macular band reaching to the inner margin, that part of it which is opposite the short band near the end of the cell being placed nearer to the outer margin, so that its inner border runs in a line with the outer border of its continuations. Beyond this band a submarginal row of darker crescent-shaped lunules enclosing large |
