are exhibited in the box, the Acraea next to the Syntomid, 
in Type I. The obvious explanation is that the ¢ Syntomid, 
by chance, had a scent corresponding to that of the 9 Acraea, 
and that the ¢ Acraea had made a bad mistake ! 
Dr. CHAPMAN observed that in view of nine of the eleven 
pairs exhibited it would seem that the darker 3 3 selected 
the lighter 9 9. 
Various InsEcTS MosTLy FROM Arrica.—Dr. CARPENTER 
also exhibited a case of miscellaneous insects and communicated 
the following notes upon them :— 
Variety of Acraea acerata, Hew. (vinidia, Hew.).—At 
Jinja, in Usoga, I caught on the Kerinya peninsula, in 
Feb. 1911, a male of this species which very closely resembles 
the male of Acraea viviana, Staud. The dark tawny orange 
of the typical acerata is replaced by a shade of yellow almost 
identical with the colour of the male viviana. 
Acraea mairessei, Auriv., very resistant to cyanide fumes.— 
The typically aposematic insects seem to have extraordinary 
powers of resistance, not only to damage inflicted by enemies, 
but to other harmful influences. A specimen of Acraea 
mairesset surprised me by being even more resistant than other 
Acraeines to the fumes of a cyanide bottle which knocked over 
other butterflies in a minute or two; this specimen, caught 
in Chagwe, Uganda, near Mpumu Hill, July 13, 1910, was 
very little the worse after half an hour in the bottle. 
At a later date, on the Sesse Islands, I wanted to preserve 
a couple of pupae of Planema consanguinea arenaria, K. M. 
Sharpe. I put them in a cyanide bottle one night, and next 
morning they were still active. I repeated this the next 
night with the same result. 
Amauris albimaculata, Butl.; scent-brand eaten out (by 
ants ?).—A male specimen which had been caught at Jinja, 
Usoga, in the second half of August, 1910, was found by Prof. 
Poulton when it arrived at the Hope Dept. to have been 
damaged, probably by ants, in a very interesting way. The 
strongly odoriferous brand in the (left) wing had been neatly 
eaten out, and nothing else had been touched. Similar 
instances of this have been given in Proc. Ent. Soc., 1907, 
p. x, where Prof. Poulton describes a specimen of Amauris
