responding in outline and position in the tM'o forms. On the tipper 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 with 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 took 

 several specimens at Natal in three different localities, all of which were fre- 

 quented by Ceryne; and in one (Tongaati Eiver) the two forms were flying 

 together about the same spot. As I at that time did not regard Tuhuoa 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.
