116 A TOUR AMONG THE ISLANDS 



all ; of butterflies, Acraea zetes, of rather Eastern type, 

 was notable, and no Nymphalines were seen. Insular 

 features of Wavuziwa were two ; a Lymantrid caterpillar 

 new to me ^ was found in abundance feeding on the 

 " Anyamberege " plant, on which plant I had never 

 previously found any caterpillar, and fluffy white masses 

 of some species of Coccidae, which thickly infested bushes 

 and undergrowth. 



On February 26th, Sege was visited ; a not very 

 interesting island of the same size as the last named, 

 rocky, covered with grass and without any beach. Rather 

 conspicuous on this islet was the fibrous leaved plant 

 found previously on Zigunga, and an aloe whose spikes 

 of scarlet blooms arose from rosettes of fleshy, thorny 

 edged leaves. 



Two Enswa-swa were found on the island ; one, the 

 biggest I ever saw, was much less timorous than usual, 

 and did not retreat into the water until I approached 

 within a few yards of it, after which it remained close at 

 hand with its head above water. 



Of bird life the only notable feature was the " Nightingale 

 flycatcher " ; Nephila was absent, Glossina very scarce, for 

 the nine boys in an hour only caught twenty-seven, all 

 males ; of butterflies, ten species were noted. 



Wait WE was visited on the 26th ; it has a central 

 grass hill rising above the level of any of the neighbours, 

 and sloping precipitously to the water on the west side. 

 It is partly clothed with bracken, and the shores every- 

 where are steep and rocky ; there is a fair variety of 

 trees and, in contrast with Sege, abundance of ferns. 

 Waitwe, like Kiuwa, is pre-eminently a " rat island," the 

 tussocky grass being penetrated in all directions by their 

 runs. Perhaps on account of this a small python was 

 found on the island, in a cave. 



Three Enswa-swa were seen ; of birds, the " Kunguvu " 



1 Eucoma otricosta.
