Closely allied to P. Vindex, (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-wing) median 
land. Fore-wing : 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 Vindex) 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 Vindex, hut hind-wing with one rather wide continuous white median 
land from costa to suhmedian nervure. Fore-wing : spots as on upper 
side. Hind-wing : close to base, four white spots, forming a more or 
less disconnected short transverse band; 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.
