except egina [Cr.] and a large rosy red one whose name I don't 

 remember, are very poorly represented. Thus, the small, 

 usually swarming terpsichore [L.] and others of that type, are 

 so scarce that I have only with difficulty found one specimen 

 of one species ! 



" The egina females vary considerably here, but I have not 

 taken specimens as pale as some that I got earlier on this trip 

 on Bulago Isle. A. zetes [L.] is of very varied form on these 

 islands, and, I think, on the whole much more eastern than 

 western in appearance. Danaines also on this isle are very 

 few in individuals. Fiske has seen a male P. dardanus [Brown], 

 but I have not come across it. 



" Lycaenids abound, but the Liptenine "mimetic forms are 

 very, very few — only a single black-and-white forest species 

 and Pentila ! But the forest seems as if it ought to be very 

 suitable indeed. It is certainly the richest butterfly forest of 

 any place I have been to. Fiske and I reckon that at least 

 there must be 150 species of butterflies in it and on the shore 

 in front. I shall be sending you the specimens when I return 

 to Entebbe towards the end of this month, with a map of the 

 island and localities. 



" Quite apart from the Glossina work there is a great deal 

 of interest in the comparative study of these various islands, 

 which present a great variety of conditions. Each one, as 

 regards Lepidoptera for instance, has certain rather distinctive 

 points. Thus, one has great swarms of common small Acrae- 

 iues, on another A. niavius [L.] seems very abundant in pro- 

 portion to the few other species. Another isle has a large 

 variety of Hesperidae. I shall never forget one minute well- 

 forested island, called Sanga, which was very beautiful when 

 one got into its little forest. The great peacock blue-and- 

 green skipper [Rho])alocampta chalybe, Westw.] abounded 

 there, and one would see, with joy unspeakable, several of 

 these glorious creatures at once, darting about or flirting with 

 each other, their tints flashing in the sun. On this island 

 Mimacraea poultoni [Neave] had been very plentiful when 

 Fiske visited it in November, but I only got one specimen in 

 February. Then on another island, where there were only 

 about half-a-dozen species of butterflies (I think four were
