the present plain I was interested to see shortly afterwards, in 

 ' Nature,' a review of an account written by a geologist who 

 visited B.E.A. (Kavirondo) and found shell beaches 300 feet 

 above present water-level." 



The next letter contained the news that he was likely to be 

 moved much further west at an early date ; also the following 

 paragraphs : — 



"November 10, 1915, Rukuba Hill. 



" I have no time for collecting where I am now, and it's not 

 a good locality like Kakindu, of which I often think longingly, 

 and look over the top of the forest which lies between us and 

 it, and think of the treasures there. 



" I have managed to rear the larva of Cosmodesmus angolanus 

 here, and it was very much like the larvae of policenes and 

 leonidas, also the pupa. I wonder if it's been described 

 before ? 



" I have also got the larva and pupa of a Nymphaline allied 

 to *Charaxes, which flies about the overgrown banana shambas. 

 It has only a single ' tail ' to the hind-wings, which are greenish 

 or creamy white with a broad light-brown border. It flies like 

 a Charaxes, and larva and pupa are both typically Charaxes, 

 so the genus must be very closely allied. We had a little 

 expedition for four days about a fortnight ago — we didn't 

 accomplish what we intended owing to an unexpected cir- 

 cumstance over which we had no control. I took my net, as 

 much of our route lay through the forest, but didn't get 

 anything much. I saw one rather interesting thing — a 

 medium-sized Acridian <3 courting the $ in a thicket. He 

 had antennae brilliant!;/ white like Baoris niveicornis — the $ 

 hadn't — and my attention was first attracted by seeing them 

 violently vibrating. At first his body was hidden, and I 

 thought they must be antennae of a large Sphegid, as they 

 vibrated in that sort of way. He was very importunate, and 

 pressed close to the female — and I lost them because she 

 moved away into a dense part of the bush and he followed." 



The next letter, written from S.W. Uganda, described the 

 journey from Rukuba. 



* Evidently C. varanes or one of the forms allied to it. — E.B.P.
