SOME EAST AFRICAN BUTTERFLIES 
48 
to their breadth, so much so as to give it a distinctive appearance 
even during flight. It is black with blue-green markings. 
These consist of a broad macular band on the fore wings 
commencing below the costa nearer the base than the tip 
and extending to the anal angle ; there is a row of three smaller 
spots near the tip, and a row of spots smaller still near the 
hind margin. On the hind wings there is a large blotch filling 
the greater part of the basal area, and two rows of spots 
near the hind margin, the inner row being much larger than 
the outer. On the under side the markings are very much 
the same, but the ground colour is pale brown except on the 
lower part of the fore wings. 
The female is a larger insect, expanding four inches, with 
the fore wings much more produced. The markings are very 
similar, but all the pale markings are larger and bluish white. 
These differences give the butterfly a very different appearance, 
and in flight it bears a considerable resemblance to the large 
black and white Amauris niavius, which is a very abundant 
and highly distasteful insect. 
This resemblance is increased by an approximation in its 
habits. I have never seen the female joining in the evolutions 
which are so characteristic of the male, but its floating flight 
resembles that of its model, and it settles frequently, if not 
generally, with its wings pendent in the same position as the 
Amauris. 
2. Euxanthe tiberius. Grose Smith. — This is an even 
more magnificent insect than the last, and is very much rarer 
with a much more restricted range. 
It is only found in dense patches of forest and seldom 
ventures out into the open. It is generally to be seen settled 
on trunks of small trees, and it is an insect of sluggish habits, 
so that it only makes short flights at a time. It is peculiar 
to British East Africa, whereas E. Wakefieldi is found as far 
away as Delagoa Bay. 
It is, however, not quite so easy to catch as it looks, as, 
when disturbed, it dodges off between the trees and settles on 
a trunk or branch, ready to take to flight at once if one follows 
it, and that always before one can come within striking distance. 
They have a habit, however, of haunting the same spot day
