fulvous patch presents an extension in the direction of the base, especially in 
the $ , where it sometimes occupies rather over the outer third of the discoidal 
cell. 
From its very near ally, P. Hippia, Cram,, this species is distinguished l)y 
its paler ground-colour, and paler, much smaller, fulvous patches on the upper 
side in both wings, and by the total absence of the dentated dark transverse 
streak beyond the middle on the under side of the hind-wing. 
This Pseudonympha haunts broken and rocky ground in elevated situations, 
but is also to be found sometimes at lower levels near mountains and stony 
hillsides. It is not uncommon on and about Table Mountain, and I have 
twice taken it flitting about the Museum enclosure in Cape Town. Its flight 
is extremely wavering and irregular, though weak and near the ground, and it 
is fond of settling on stones or on the soil. On the 4th April 1872 I took 
the paired sexes near the summit of the Lion's Head Mountain. The butterfly 
appears in the months of September and October, but I once met with it 
towards the end of August. It is, however, more numerous near Cape Town 
in March and April, and it was in March that I found it sparingly in Natal. 
Near Grahamstown I took it pretty commonly at the end of January and in 
February.
