_N. Etheocles_ is a native of Africa, and is found chiefly on the coast of Guinea. It is nearly of the size of _C. Jasius_; the surface greenish-black, with a broad white band running obliquely across the middle of the wings; on the primary wings this band is divided into spots and contracted anteriorly, having a group of three or four small white spots on the inner side near its origin. Besides the white band, which is regular and continuous, the under wings have a row of white crescents parallel with the hinder border, succeeded by a black line, the border itself of a lighter green than the general ground colour, and having a few rust-coloured crescent-shaped marks. On the under side the prevailing colour is pale brown, somewhat glossy, with a white band similar to that described; three ocellated spots are observable at the base of the upper wings, and in the same situation on the other pair are three black transverse lines edged with blue. The internal angle of the superior wings bears a double black spot, and a series of violet lunules runs along the hinder border of the under wings; the border itself green marked with a row of black points.

Extent of the wings nearly four inches, the surface very dark blue approaching to black, the nervures brown; beyond the middle are two transverse rows of small round spots of pale blue, and along the hinder margin a series of small dull yellow crescents. The ground colour beneath is brownish-grey, somewhat glossy; the superior wings having a few transverse waved streaks of black edged with blue towards the base, then a few yellow streaks succeeded by a pretty regular row of yellow spots, and on the internal angle are two black spots, partially or wholly surrounded with blue and surmounted by yellow crescents: under wings marked in a manner somewhat similar to the upper pair at the base; the hinder margin with a continuous row of violet ocellated spots, preceded and followed by a row of yellow lunules; tails rather short and slender, brown; body dark brown above with four whitish points on the head, the under side inclining to yellow, antennæ black, the palpi yellow beneath. Found in the islands of Java and Amboina. PERIDROMIA ARETHUSA. PLATE XVIII. Fig. 1, _Fem._ [Illustration]
