Tliis species is about the size of P. asterias. Upper side, the 

 wings denticulated, black, with the notches yellow ; the anterior 

 Avings have on their hind margin a row of six or seven pale yellow 

 spots, which gradually increase in size, from the costa to the inner 

 margin. They have beyond this a spotted band of four or five 

 small and obscure spots placed in a line, and formed of greyish 

 atoms. The posterior wings have a marginal series of seven 

 luDules, the first of which is orange, whilst the other six are of a 

 greenish or bluish grey. Inside these marginal lunules is a broad 

 bluish grey band, divided by the nervures ; the lunule of the 

 anal angle is triangular, orange on its inner margin, and greenish 

 grey on its outer. The tail is black, very short, and a little swollen 

 at its extremity. Under side, the wings brownish black at the 

 base. Anterior wings, with the spots of the upper side much better 

 defined, so that they here form two spotted bauds ; they have also 

 two triangular yelloAv spots which are placed beyond the others. 

 Posterior wings with two bands, each formed of six orange lunules, 

 a little tinged with yellow on their edges. The anal spot fulvous, 

 only tinged with grey on its outer edge. Between these two 

 spotted bands there are seven glossy blue lunules, the third of 

 which is partly covered by a verticle oblong spot, generally of a 

 greenish grey. The body is black with some reddish dots on the 

 front of the thorax, and a series of yellow spots on each side. The fe- 

 male differs from the male in the following particulars : the anterior 

 wings are generally destitute of the marginal row of yellow spots, 

 the second row being seldom or never indicated by any greyish 

 atoms ; the posterior wings have above the marginal lunules a sort 

 of band badly defined, rather broad, and formed of shining blue 

 atoms, whilst in the male this band is better defined, and of a 

 bluish or greenish grey. The under side differs but little. 



The caterpillar is green, with a yellow marginal band, which 

 mixes itself a little with the green color. It has upon the sides 

 two rows of blue dots, and upon the fourth segment two flesh 

 colored spots, upon the third segment a flesh colored eye spot with 

 a deep blue ocellus, and upon the first a black collar. The under 

 side of the body and of the head are of a flesh-colour, a little 

 tinged with ferruginous. All the feet are ferruginous, but at the
