about the twenty-fourth we have visited, and it is certainly 

 the most beautiful. From the Tse-tse point of view it is a 

 great success, and is of much interest in that Glossina is more 

 abundant at one locality (a beach in front of thick forest) 

 than I have ever seen it before. What do you say to one boy 

 catching 78 in half-an-hour ! 



" The island is only a mile or two in gi'eatest diameter, and 

 we have only worked the south shore where there is a steep 

 slope covered with forest and old banana plantations leading 

 down to a beach several yards wide. Never have I seen so 

 many butterflies congregated anywhere. Patches of this 

 beach were favourite drinking-places, the sand being moist, 

 and dozens of butterflies were sitting as closely packed as they 

 could be, drinking. The long-tailed green Cosmodesfnus 

 [probably policenes, Cr.] was the commonest Papilio, but 

 several other kinds of forest Papilios came down, many species 

 of sulphur-coloured and black-and-white Pierids, flocks of 

 AteUa phaJaiitha [Dr.] such as I have never met before, and 

 many species of Lycaenids ! I have got specimens of most of 

 the species we saw. Then in the forest and jungle at the back, 

 all sorts of very nice things — half-a-dozen or more species of 

 NejJtis, Charaxes at least nine species, interesting skippers and 

 blues, and forest Nymphalines whose names I know not. 

 Euralias, however, were, curiously enough, absent : neither 

 Fiske nor I have seen one here. Pseudacraea hoisduvali [DbL] 

 I saw once only, and could not catch, but it was, I think, of 

 western type. Ps. lucretia [Cr.] was extraordinarily common, 

 and I was much interested by the fact that Fiske, who did not 

 know it, took it for a Neptis. You remember that I told you 

 how I thought it was more like a Nejjfis on the wing than 

 anything else. Ps. eurytus f. geogr. hohleiji [Neave] is fairly 

 abundant, and I have got 6-8 specimens, but all of the type 

 form hobleyi : I have not seen either terra [Neave] or ohscura 

 [Neave] or transitions on this island. This is the more to 

 the point because the only Planema models I have seen, or 

 that Fiske has seen, are those of the hohleyi pattern. Rather 

 nice, isn't it ! 



" A curious point about the Lepidoptera of this island is that 

 Acraeines are very few in species, and those that do occur,
