There are two forms of females. The first form is scarcely distinguishable 

 from the same sex of P. aegeiis Donovan, and from the dark form of that sex of 

 P. omienns. The second form resembles the variety named P. amanga Boisd. 



Hah. Both sexes from llunilioUlt Hay, and one female, of the amavga form, 

 from Mansinam.

Mali:. — Upperside: both wings brown black. .\n(erior wings dn.-^tcd with a 

 few ligiiter brown scales towards the apex. Posterior wings with the disc crossi-d 

 by a whitish band as in P. pandion, but somewhat narrower, that part of tiie 

 hand which lies between the submedian nervure and the inner margin nearly 

 obsolete, with a few blue scales below it. 



Underside: both wings brown. On the anterit)r wings towards the ai)ex are 

 ravs of grev scales divided by the nervures, and a small patch of similar scales 

 between the second and third subcostal nervules. The disc of the ))Osterior 

 wings is crossed by a curved row of narrow indistinct bluish grey Innules, the 

 two lowest being double ; above the anal angle is an indistinct red patch crowned 

 with an indistinct bar of blue scales. 



FEM.4LK. — There are two forms of this sex; the one resembles the dark 

 form of the female of P. pandion, but the spots are whiter, more distinct, and 

 more extended inwardly ; on the posterior wings the white central area is more 

 rounded, the white radiating bars of that portion of the white central area 

 which lies beyond the cell being concave and more clearly defined at their outer 

 ends ; there is a submarginal row of narrow ferruginous red lunulcs becoming 

 obsolete towards the anal angle, where there is an interrupted red spot with 

 a few blue scales above, followed by another larger patch of blue scales between 

 the submedian nervure and lowest median nervule. 



Underside as above, the white spots being very distinct. I)n the posterior 

 wings is a curved submarginal row of red luniilar sjiots, above which is a row 

 of narrow blue lunules. 



The other form of the female resembles the amaii(/a form of the ]>receding 

 species but is whiter; on the upperside of the po.sterior wings the white area 

 below the discoidal nervule and thence to the abdominal margin is extended 

 nearly to the outer margin. At the anal angle is a large tawny patch divided 

 by a black bar centred with blue scales, another tawny i)atch between the 

 submedian nervure and lowest median nervule, aliove which is a large black 

 patch with a few blue scales at its upper end, and a row of three indistinct 

 fuliginous patches between the succeeding nervules, the two n])piTmost nrarlv 

 obsolete. 



Under-side: both wings as above. Po.sterior wings with a submarginal row of 

 lunules, the three uppermost ferruginous red, thence becoming more difl'used and 

 bright tawny to the anal angle, where that colour extends upwards partially along 

 the abdominal fold; between the tawny space and the white central area is a 

 row of dark brown black spots of irregular size and shajje, the two uppermost 

 merging in the brown black of the costal and a])ical area.
