This species is closely allied to P. Panope, in the style 

 of the markings of the hind-wings ; but, on the upper 

 side, all the wings are of a rich blue-black, the anterior 

 being entirely immaculate,* and elongate triangular, 

 whilst the hind-wings are subtriangular, the apical mar- 

 gin appearing as though truncate instead of being rounded 

 as in P. Panope. The sinuations of the hind-wings are 

 of moderate depth, with whitish incisures ; these wings 

 are marked beyond the middle with a row of five large 

 spear-shaped marks, followed by a row of lunules, of 

 which the inner one is fulvous, and the four others cream 

 coloured, followed towards the outer angle by two oval 

 spots of the same colour ; the marginal incisures are very 

 slenderly buff coloured, those nearest the anal angle 

 being orange ; the head and anterior part of the thorax 

 are spotted with white as in P. Panope, and the abdo- 

 minal segments are marked with slender white lines at 

 the sides. 



The underside of all the wings is a rich red-brown, 

 with a slight purple tinge seen in certain lights ; the 

 fore-wings are immaculate, except a few white scales at 

 the base, of which there are also two patches at the base 



* With a lens, a very few luteous scales can be perceived in those parts 

 of the fore-wings near the apical margin, where the cream-coloured row 

 of spots are developed in P. Panojpe.
