SOUTH-AFRICAN BUTTERFLIES. 
(in hind-wings scarcely distinguishable) to a broad space of pure-white occupy- 
ing nearly all the disc except the upper part. 
Bihulus has a wide range over Eastern South Africa, and is recorded also 
from Mozambique. In the Cape Colony I am not aware of its occurrence to 
the west of Port Elizabeth. The butterfly is by no means uncommon ; it 
■usually flies but little, keeping about the minor branches and twigs of shrubby 
plants. When at rest on these, it is with difficulty to be seen, the pattern and 
colouring of the under side according well with the bark and lichens, while the 
densely woolly legs form a solid base to the insect, disguising its real character 
and increasing its likeness to some vegetable growth on the twigs. The (Js 
appear at times to exhibit more activity. Colonel Bowker having in 1865 
written from the Tsomo River in Kafiraria that the butterfly was " very nume- 
rous at the Ohita, Kreli's old kraal," and that " the ^ s kept flying, often five 
or six together, about the tops of the trees, darting and whirling round and 
round like a lot of flies ; while the 9 s were quietly settled on the trees, feeding 
on the moisture from the bark or on the injured galls of the wild vine." 
I have met with Bihulus pretty numerously in the height of summer, from 
the end of January to the end of March, and rarely in the winter, during June 
and August. Colonel Bowker has also captured it in May.
