marginal diffuse white line, interrupted by the rather prominent 

 veins ; and a dark anteciliary line, cilia as above. Hind-wing : 

 ground-colour rather darker than on fore-vrings, more brownish, 

 the basal area suffused metallic greenish, a faint white spot in cell 

 followed by a large white broadly wedged-shaped mark, the ba&is of 

 which is the spot on the discocellulars — no similar submarginal 

 white mark. Beyond this a series of 9 ocelli similar to those on 

 fore-wing, the first, in area 16 indistinct, the remainder prominent, 

 the last two both in area 7, the series sinuous from 1 to 6, then bent 

 at right angles, 6, 7, and 8 being in line, 9 towards the base of area 7. 

 Marginal ai'ea whitish, well separated from the ocellar series, in- 

 wardly diffuse, enclosing a double series of fine black crescents 

 except in area 7, each pair enclosing a faint orange spot. Cilia as 

 above, preceded by a fine dark anteciliary line. The veins promin- 

 ently paler than the ground-colour. 



$. Upperside, both ivings : brilliant blue, of a deeper shade than 

 in (J, the margins and costal areas, especially of fore-wing, broadly 

 and diffusely black, enclosing scattered blue scales. Cilia as in (J- 

 Underside, both vsings : as in the (^, but with no spot in cell on fore- 

 wing, and the marginal pale markings much broader and more 

 diffuse. On the hind-iving the inner series of crescentic marks almost 

 obsolete, the outer prominent, the two series more widely separated, 

 the orange more conspicuous. 



Length of fore-wing, q 15-19 mm. ; 9 14-18 mm. 



The series exhibits considerable variation. On the 

 upperside in the (^ the black margins vary in width and as 

 to the definition of the inner edge, especially on the fore- 

 wing; in the $ the blue suffusion is in some specimens 

 confined to the base of the wings with only a few scattered 

 scales on the disc, and in these specimens the hind-wing 

 bears a submarginal series of diffuse bluish lunules, which 

 in one specimen are distinctly marked with orange. On 

 the underside, the veins, usually very prominent, do not 

 stand out in all specimens, the ocellus in the cell of the 

 fore-wing is as frequently absent as present, the relative 

 prominence of the ocelli as between each other varies 

 considerably, as also does their size ; but their heavy white 

 ringing and the extraordinary dark smoky ground-colour 

 are very constant. The orange submarginal markings of 

 the hind-wing, always very pale, in some specimens are 

 barely traceable, in others almost as large as in P. arene. 

 The genitalia exhibit marked differences from those of 

 P. arene.
