Lycaenids), the woolly legged Lycaenid, I think Uranoihauma. 

 was quite surprisingly common. 



" On Sanga also was another feature. A very conspicuous 

 Geometrid larva (which I suspect to be Aletis) abounded to 

 such an extent that it had defoliated and killed very many of 

 its shrubby food-plants. It was orange with black blotches, 

 and had a curious habit of resting — unusual for a Geometrid. 

 It just hung vertically downwards, without the aid of any 

 supporting thread, from a twig or bared leaf mid-rib, absolutely 

 conspicuously and in crowds together. 



" On other islands other features were noted : — great 

 abundance of a species of slug, of Chrysopsyche larvae, of a 

 rodent living in thick grass, of Coccids making woolly masses, 

 etc. 



" Several islands have an unpleasantly large number of 

 enormous spiders' webs, in which I have seen a sun-bird caught 

 fast. The webs form sheets, stretching across open spaces from 

 tree to tree and not in one plane only. Numbers of them are 

 spun one behind the other so closely that one wonders how on 

 earth the owners of the middle webs ever get anything to eat ! 

 And indeed many of them look half -starved ! Yet on other 

 islands near by the species seems hardly able to hold its own : 

 it is just there, and that is all one can say ! 



" The birds also are interesting : there is a small brown fly- 

 catcher with white throat and belly which seems to prefer only 

 the tiniest islets, a few hundred yards square, where one finds 

 it amongst thickets of a mauve Composite weed. It has a song 

 very suggestive of a nightingale. On another island I heard 

 a thrush singing so sweetly that it made me feel very homesick. 

 Its song struck me as very curious, because, although the bird 

 abounds at Entebbe, I had never heard it sing either there or 

 on Bugalla ! I thought perhaps it only occurred near human 

 habitations, and yet here it was on just one island out of the 

 many visited. 



" There was another extraordinarily interesting thing about 

 Sanga island. Birds seemed extremely scarce, especially 

 such as might eat Lepidoptera. Now I quite soon noticed that 

 some of the butterflies were very much easier to catch than 

 they had been on Bugalla. Large Euralias, for instance, were
