which it differs in its inferior size, less falcate primaries, more 
opalescent discal belt, deeper coloured more varied under 
surface, with submarginal pearly white lunules; the primaries 
washed with purplish.

I have only seen the wet phase of this species, of which 
there are four examples from the Cameroons in the Hewitson 
Collection. The dry phase should be larger than the wet, 
with more faleate primaries and with the under surface more 
plainly coloured, but with a better-defined dark central line 
across the wings, if it differs as in the allied species.

This insect runs somewhat close to P. tugela, of which it 
has been regarded as the wet phase. We, however, possess 
forms representing the wet, intermediate, and dry phases of 
both, and to unite them as one species would greatly compli- 
cate this already difficult group, by proving that in each 
phase forms with more or less faleate primaries occurred. 
Therefore until the identity of P. awrorina and P. tugela can 
be proved by breeding one from eggs laid by the other, it 
seems to me more convenient to regard them as different 
species. In what I call the wet phase of P. aurorina the 
primaries are angulated, the secondaries below are largely 
ochreous, the whole discal belt being of that colour; in the 
supposed dry phase the primaries are slightly falcate and the 
wings below are bright chestnut, irrorated with purplish ash 
on basal area and external border. We have a long series of 
an intermediate phase.

This always has the primaries strongly falcate and with a
