236 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. 



Bibulus 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 difificulty to be seen, the pattern and 

 colouring of the under side according well with the bark and lichens, while the 

 densely Avoolly legs form a solid base to the insect, disguising its real character 

 and increasing its likeness to some vegetable growth on the twigs. The ^ s 

 appear at times to exhibit more activity. Colonel Bowker having in 1865 

 written from the Tsomo River in Kaflraria 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 $ 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 Bihdus 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.
