3. The butterfly Pavrttio (CosMoDESMUS) LEONIDAS 
(No. 147) mimicking the Danaine TIRUMALA PETIVERANA. 
Both model and mimic are pale blue with a coarse black 
pattern. 
M, held the Papilio in his hand and looked at it for a 
long time, then having tasted it gingerly, ate it without a 
sign of dishke (Obs. 322). This suggests that M, had an 
instinctive feeling that it was an inedible butterfly, but 
having tasted and found it good, ate it. This appears to 
mean that the butterfly is pseudaposematic, but further 
evidence is required. 
4. The Astuip fly (No. 67) mimicking a Hymenopterous 
insecl (SCOLIID). 
This large fly has the abdomen covered with golden 
pubescence, and the wings clouded with brown, both 
characters giving it, with its w ings folded in a position of 
rest, very much the appearance of a Scoliid. The first one 
I found was sitting fully exposed on a leaf in the late 
evening, and [ was much struck with its resemblance, 
which was increased by the suppression of the large bristles 
so common in Asilids. It was offered to M, in a box 
(Obs. 129); he looked closely at it, but with suspicion. Just 
as 1t was about to fly away I caught it by the legs, so that 
the yellow pubescence of the abdomen was fully visible. 
M, would not catch hold of the fiy, although he once put 
ut his hand and gently touched a wing. The fact that on 
another occasion M, took and ate readily another equally 
large, and bristly member of this family of normal Asilid 
appearance (Obs. 142) shows that he was not objecting to 
the first because it was an Asilid. M, (Obs. 620, 673) 
handled the fly equally gingerly, but eventually found it 
was good to eat: This resemblance to a Hymenopteron 
would seem to be a case of true Batesian mimicry. 
5. Female Asilid fly (No. 382) mimicking a bee. 
The fly is sexually dimorphic, the 3 being uniformly 
black, the Q brown and bee-like. M, ate a male without 
hesitation, but his behaviour with the female (Obs. 874) 
left little doubt that he thought it was bee-like. 
Since it was eventually eaten with satisfaction the female 
ae to be pseudaposematic; a case of true mimicry. 
6. Syrphid fly (HRISTALIS TENAX: No. 61) mimicking the 
honey-bee. 
Just as the English honey-bee is closely resembled by 
Eristalis tenax, so 1s the African form of the sarhe species,
