Closely allied to P. Vindcx, (Cram.). White spots similarly ar- 

 ranged, hut mostly somewhat larger, notably so {in fore-wing) last spot of 

 discal series and third of suhmarginal series, and {in hind-iving) median 

 hand. Fore-vying : third spot of discal series not (or but very slightly) 

 extending below first median nervule, but fourth (last) spot larger 

 (very much larger than in Vindcx) and subquadrate ; submarginal 

 series of small spots more sinuate. Hind-wing : median band much 

 wider inferiorly, being of almost even width throughout, much more 

 curved, not marked by crossing nervures. Under side. — Colouring as 

 in Vindcx, hut hind-wing toith one rather wide continuous white median 

 hand from casta to sid)mcdian nervure. Fore-2oing : spots as on upper 

 side. Hind-wing : close to base, four white spots, forming a more or 

 less disconnected short transverse baud ; both inner and outer edges 

 of median band irregularly dentated, the band itself being widest on 

 costal edge and bisinuated, with a rather acute inward projection 

 between median nervure and its first nervule. 



The characters italicised appear to be quite constant, and serve well to dis- 

 tinguish this species from Vindex. It is common about D'Urban in Natal, 

 where I took it in June 1865, and again in February and March 1867. I 

 have received a dwarf ^ from the Gaboon which expands only ten lines across 

 the fore-wings.
