48 Dr. G. D. H. Carpenter’s Baperiments on 
Obs. 546. Sp. 186.—Five staple Acridians (Catan- 
tops decoratus) eaten with zest. 
Series Bh. Obs, 547-548. Jan. 29. 
Series Bi. Obs. 549-563. Feb. 1. 
Series Bj. Obs. 564-581. Feb. 2.—At 2 p.m., M. having 
had food, but no insects— 
Obs. 570. Sp. 47.—Buprestid, Agrilus discolor: a 
pair of these beetles found in copula conspicuously 
exposed on a leaf. One was offered to M., who looked 
so long at it that I thought he was not going to take 
it. Suddenly, with decision, he took and bit it, and 
then ate it without further hesitation. 
(Note.—The grey, black, and rose tints of this beetle 
and their arrangement somewhat remind one of the 
similar colours common among Hemiptera; and M.’s 
behaviour rather suggested that there may be a 
deceptive resemblance. If so, the mimicry is pseud- 
aposematic, for the beetle was very edible.) 
Series Bk. Obs. 582-586. Feb. 3.—At 2 p.m., having 
had some food, M. eager for insects. He refused a 
Cetoniid (Diplognatha silicia) and then ate 15 grass- 
hoppers. 
Obs. 585. Sp. 278.—Chrysidid: a medium-sized 
“ fire-tail wasp”’ of the usual brilliant green, with 
blue tip to the abdomen. M. looked long at this, 
then took it and ate it, to my great surprise not 
getting stung. 
(Note.—It is: very likely that M. had not met one 
of these before—it will be noted that he looked at it 
a long time. These formidable, stinging insects are 
hard and highly conspicuous.) 
Obs. 586. Sp. 279.—Galerucid, Exosoma ugandaensis 
Jac.: asmall, gregarious, conspicuous beetle found on 
low herbage; head and thorax black, abdomen brown. 
It was smelt and dropped ; I offered it again, with 
the same result. 
Series Bl. Obs, 587-595. Feb. 4.—In afternoon, M. being 
eager for insects— 
Obs. 590. Sp. 280.—Cassidid: a large “ tortoise- 
beetle,” fiery orange-pink spotted with black, and 
translucent. Very conspicuous on the wing. M. 
ignored it at first, then took and dropped it. Then, 
because I wanted to take it for record, M. ran off 
with it and pulled it to pieces, but ate none.
