Butterflies of the Genus Precis. 209 
process is considerably reduced and the apex more angular, 
the apical portion of the wing from below the falcation to the 
costal margin being distinctly broader; the under surface with 
more distinct transverse markings than in the dry phase, 
without the olivaceous suffusion or sharply defined yellow 
central line. It is, of course, possible that P. tugela may 
have six developments from extreme wet to extreme dry, and 
that the first three may represent P. aurorina and the last 
three P. tugela, only there is rather a wide break between the 
third and fourth of these forms, which makes me hesitate to 
unite them.

The wet phase is considerably smaller than the dry, has 
the primaries subfaleate in the male, falcate in the female ; 
the under surface with tolerably defined markings upon a 
tawny ground, which is slightly washed with lilac on basal 
area and near to outer margin: the dry phase has the pri- 
maries faleate and with well-defined process in both sexes; 
the under surface with ill-defined markings on a slightly 
opaline clay-coloured ground. We also have an intermediate 
phase.

The wet phase is smaller than the dry, the apex of the 
primaries subfaleate ; the dry phase has the primaries falcate 
and produced into a long process. Indeed, the seasonal 
differences in this species are so marked that it would not 
take much to convince me that P. aurorina and P. tugela 
were forms of one extremely variable species. The wettest 
phase of P. aurorina does not differ more from the driest 
phase of P. tugela than do the wet and dry phases of 
P. eurodoce. By the way, why did not Prof. Aurivillius 
include this in his collection under P. milonia? It differs no 
more than the other species do.
