The percentage of the three commonest mimics is thus much 
higher than we should expect ; but on Damba Island, so far as 
could be judged from Dr. Carpenter’s collections between the 
beginning of May and the end of September, the results are 
far more astonishing. The only Planema models in the whole 
collection are a single female macarista and a single female 
pogger nelsoni in the second half of August, and a single male 
macarista captured on Aug. 8-9. All these specimens were 
taken in the jungle. In spite of the immense predominance 
of P. terra, not asingle Planema tellus platyxantha appeared in 
the collection, nor was there a single P. epaea paragea. Even 
more striking was the absence of P. arenaria, by far the 
most abundant Planema in the forests near Entebbe.t 
* Quoted from ‘‘Mem. I. Congr. Internat. d’Ent., Brussels,” Vol. II, 
p. 483, 1910. This paper contains a nearly complete list of captures, be- 
tween the above-mentioned dates, of all the species concerned, except 
Planema paragea and Pseudacraca obscura. The proportions of these two 
latter were taken from a list recently prepared by Mr. C. A. Wiggins and Prof. 
Poulton. In the course of this work it was found that one or two days’ 
captures had been accidentally omitted from the paper referred to above. 
t The results quoted above are not due to the captor’s selection, and, 
so far as the limited numbers go, may be depended upon in attempting 
to form an estimate of the proportion of models and mimics in the jungle. 
This was Dr. Carpenter’s first experience of these extraordinarily close
