responding in outline and position in the two forms. On the upper side 
Tukuoa wants, or only slightly presents, the pale suffusion of the inner part 
of the common discal band; in the fore-wing, the centre of the first spot in 
the discal row is blue (not white), and the bluish scaling in the discoidal cell 
is more pronounced. The cilia are much narrower, and faintly (instead of 
very conspicuously) varied w^ith white. On the under side the conspicuous 
ochre-yellow ground-colour and white black-edged markings of Ceryne are 
obliterated, only their outlines being indicated in grey ; while the narrow 
median yellow stripe (corresponding to the inner part of the discal band of 
Ceryne) is externally sharply dentated. 
In station and habits there seems to be nothing to distinguish this species 
from P. Ceryne, but it is apparently scarcer. In March and April 1867 I ^^ok 
several specimens at Natal in three different localities, all of which were fre- 
quented by Ceryne; and in one (Tongaati Kiver) the two forms were flying 
together about the same spot. As I at that time did not regard Tukuoa as a 
distinct species from Ceryne (and indeed had not identified the butterfly with 
Wallengren's insect), it is not unlikely that I may have passed it over at 
several of the other localities I visited.
