Dr. G. D. H. Carpenter’s Haperiments on 
the pubescent elytra dull black with four large white 
spots. I allowed this mimetic beetle to run within 
reach of M., who appeared afraid of it, pawed it, and 
at once ran out of reach; this he did several times, 
and at last ate it very quickly with no sign of dislike. 
(Note.—In a way this was disappointing, as I had 
hoped M. would leave it alone. Nevertheless he has 
eaten Mutillids on other occasions. The manner in 
which he ran out of reach after delivering his attack 
suggested very strongly that he was afraid of a sting 
from the Mutilloid insect; for although a Carabid of 
similar size would be pawed, M. would not run away 
from it. Moreover, had M. thought it was a Carabid 
beetle I believe he would not have eaten it at the end 
of a long experiment when he had had abundance of 
insect food. A point of considerable interest is that 
this mimetic beetle seems to have lost the extremely 
unpleasant acrid smell emitted by most members of 
its family—it could not be made to produce it by 
repeated interference, or even by pressing it down on 
to a hard surface. One is tempted to conclude that 
in the absence of its defensive weapon it has come to 
resemble the powerfully stinging aposematic Mutilla. 
Even the Mutilla, however, is tackled on occasion, 
and eaten by M. !) 
Series Bd. Obs. 485-503. Jan. 27.—At 4 p.m., M. being 
ready for insects— 
Obs. 493. Sp. 239.—Fulgorid, Hypselometopum 
morosum Westw.: a fairly large Homopterous species 
kicked up from low herbage; the tegmina speckled 
brown, very procryptic. The wings were tinted with 
rose, the abdomen whitish, waxy. I held it m my 
fingers so that the rosy wings could be seen. M. 
took it and looked at it for a very long time, pulled 
off one tegmen, put the insect into his mouth and 
closed his lips over it without biting it, pulled it 
out again, looked at it, pulled off the other tegmen 
and both wings, looked long at the waxy abdomen, 
and at length ate it very doubtfully. 
Obs. 499. Sp. 244.—Cerambycid, Anubis (Oligos- 
merus) limbalis Har.: a small, slender, bright green 
Longicorn beetle with the long black antennae tightly 
curled back at the tips. Like our “ musk-beetle,”’ it 
has a strongly aromatic, rather pleasing odour. I
