after day and week after week, so that having discovered its 
haunts one always has a chance of finding it at home. 
This species expands about three inches, the female some- 
times a little more, but there is not the great disparity which 
there is in the last species. The markings of the fore wings 
are similar to those of E. wakefieldi, but the spots of the 
macular band are a little smaller and it begins on the costa 
nearer the base. Between this band and the base there is 
a blotch of rich fulvous. The outer row of spots is also nearer 
the base and consists of four spots larger than in E. wakefieldi ; 
all these spots are pale green and are a beautiful contrast to 
the black ground colour. The marginal row of small spots 
is pure white and conspicuous. 
The hind wings are dead black, with a marginal row of 
small white spots and two or three spots of another row inside 
them. The under side is very similar, but the hind wings are 
rich dark brown with the nervures and inter-nervular streaks 
black. The female is very similar except that all the pale 
markings are whiter and there is a very large white blotch in 
the basal half of the hind wings. 
It is a mimic of Amauris ochlea, which is common in the 
Coast district. I have little doubt that both these Euxanthes 
are somewhat distasteful. They are both very conspicuous 
on the wing, and E. tiberius especially is very difficult to kill 
by pressure between the finger and thumb, which is very 
characteristic of distasteful butterflies. The undoubted mimi- 
cry which they exhibit towards the genus Amauris should 
therefore be regarded as Mullerian, and it is now thought that 
this mimicry is very usual amongst Lepidoptera.

Along the western shore of Lake Victoria there exists a long 
tract of uninhabited and almost uninhabitable country, save 
by birds, innumerable crocodiles, and occasional hippo, for 
unfortunately throughout the greater part of its length it
