well-known toughness of aposematic species. In a 
typically procryptic, jumping grasshopper the hind 
legs are easily dispensed with. Dzctyophorus does not 
readily exude froth, and when it does so, only a little,

Obs. 117. Sp. 61.—At 8 a.m., M. having eaten no 
insects, I gave him the Syrphid fly, Hristalis tenaz, 
much resembling the honey-bee. I held it by the legs 
so that it buzzed. M. was not at all keen, but took it 
in his hand and then suddenly let it go precisely as if 
he had been stung. I think he was very uncertain 
about this mimetic insect, and perhaps it buzzed in 
his hand and his imagination was too strong for him ! 
Obs. 128. Sp. 65.—Lygaeid, not in British Museum : 
probably a Lygaeus, a conspicuous black and red bug. 
One which had been turned out on to the ground took 
to flight suddenly; M. pounced on it and hastily bit 
off its head. This he violently spat out, and _ his 
gestures and expression gave every sign of a very 
disgusting taste. He then went and ate some mango ! 
Obs. 129. Sp. 67.—Asilid, Hoplistomerus serripes 
F.: a large predaceous fly whose abdomen is covered 
with dense golden pubescence; the wings are clouded. 
Found sitting on a leaf one evening it much resembled 
a Scolid, the large bristles characteristic of Asilid 
flies being suppressed. I opened the box in which it 
was and let M. see it. He looked closely at it, but with 
suspicion. Just as it was about to fly I caught it 
by the legs, so that the yellow surface of the abdomen, 
concealed when the wings were at rest over the back, 
was visible. M. would not catch hold of the fly, 
though he once put out his hand and touched it. 
Eventually it flew away. M.’s behaviour most strongly 
suggested that he was afraid of this harmless insect. 
Series T. Obs. 135-138. Jan. 3. 
Series U. Obs. 139-148. Jan. 3.—At 5 p.m., after M. had 
eaten some banana— 
Obs. 142. Sp. 73.—Asilid: a large, hairy, pre- 
daceous fly, grey in colour. This had been quieted 
in the killing-bottle so that when I opened the box 
in which it was it crawled out. Just as it made ready 
to fly M. seized and ate it eagerly. 
(Note.—This is interesting because M. had refused 
to have anything to do with the previous Asilid,
