appearance when one gets a glint of crimson as it flashes 
past. Another interesting point is that this butterfly 
seems, at first, to rely for its protection upon the appear- 
ance of its upper surface. It is not always an easy species 
to catch; and if one strikes at it and fails, it will settle 
again and open and close its wings, displaying the colouring 
of the upper sides. If, however, one follows up and strikes 
again so that it is really alarmed, it will fly off and make use 
of the markedly procryptic, dead-leaf like appearance of 
the underside, sitting motionless with the wings brought 
together over its back. I endeavoured to obtain ova from 
captive females, putting them with branches of the 
aromatic herb before mentioned, but was unsuccessful. 
The early stages are, I believe, not known. 
ComBINATION II. 
Seven examples of the principal model, the female of 
Pl. macarista (Plate XXXVI, fig. 1), were taken. A 
second model is provided by the female of Pl. alcinoe 
camerunica, of which 2 were captured, together with 8 
males. The resemblance between these two female 
Planemas is extraordinarily close, so that it was a very 
long time before I was able to differentiate them. The 
male alcinoe is totally different and is of a type common 
in W. Africa, but comparatively rare in Uganda. 
The black-and-white female of Acraea jodutta—the 
jodutta form of female—is beautifully synaposematic with 
the two Planema models. Of this mimic 3 were taken. 
The models are closely mimicked by the abundant 
female of the form tirzkensis (Plate XXXV, figs. 5, 6, 9; 
XXXVI, fig. 8) of Pseudacraea eurytus hobleyi, of which 
40 were taken. 
ComBINATION III. 
The model is the eastern form, paragea (Plate XXXVI, 
fig. 7), of the western species Planema epaea. Of this 
41 males and 34 females were taken, so that it seems not 
uncommon. But these figures give a quite dispropor- 
tionate idea of its relative abundance in the forests. I 
happened to hit upon a locality at the edge of the forest 
where the species seemed to collect in numbers owing to 
the attractiveness of certain flowers, and I naturally made 
a point of visiting this locality every evening, since I 
wanted as many specimens as I could obtain. Had I
