other, remaining motionless in these positions. Perhaps, as 

 some Acraeine pupae at any rate are of aposematic colours, it 

 is an advantage to show by change of position that they are 

 animate objects, and drive home the warning, I have never 

 seen any other pupa that hangs by the tail adopt changes of 

 attitude." 



PSEUDACRAEAS OF THE HOBLEYI GROUP ON THE SeSSE IsLANDS 



IN THE Victoria Nyanza. — Prof. Poulton said that Dr. 

 G. D. H. Carpenter had left Damba in December 1911, and 

 after spending Christmas at Entebbe had gone in January 

 to Bugalla Island in the Sesse Archipelago. The following 

 extracts were printed from a letter written in February : — 

 " 1 am now quite settled, and am going to remain on Sesse. 

 The fly have become very much more numerous lately, and are 

 quite as numerous as I want. The change from Damba is 

 very welcome, the scenery here being quite different. The 

 island is mostly open grass land, rising some 200-350 feet 

 above the lake, with patches and belts of forest here and there, 

 and a belt of forest all along the coast. I went into this last 

 Sunday, January 28th, and to my great delight found there 

 representatives of all the Flanema-Pseudacraea associations ! 

 So neither you nor I need regret that I have left Damba. 

 Ps. ohscura seemed almost more abundant than on Damba, and 

 its model \^Pl. paragea'] too (by the way, this seems to have 

 more yellow on it than the Damba specimens) ; and on the 

 very first time I went there I caught the most lovely specimen 

 of a Pseudacncea intermediate between Ps. terra and Ps. ohscura 

 — far better than anything I ever got on Damba. In what 

 I now regard as my apprenticeship to the Pseudacraeae I 

 cei-tainly tvas misled, as you suggest, by the rudimentary vein 

 closing the hind cell. But now I can, with a certain degree 

 of confidence, distinguish them from their models on the wing 

 and at rest. Pseudacraeas are very much more alert, and 

 rarely rest with the complete * abandon ' of the Planemas. 

 Moreover, Ps. ohscura and terra have a curious shiny appear- 

 ance about them, especially on the under surface, as if they had 

 been varnished ; and, in the * cadaver,' I find very many points 

 of difference. Pseudacraeas have much thicker bodies; the 

 palpi are larger ; the antennae have practically no club, only
