Experiments on Mantidz in Natal and Rhodesia (G. A. K. M.), 
pp. 297-318.. 
[Summary of these experiments] (E. B. P.), pp. 313-315. 
Conclusions from experiments on Mantide (E. B. P.), pp. 315-319. 
“We may safely conclude that outside the Acreinze, and doubt- 
fully the Danaine, Mantide devour butterflies very freely, 
the species with warning colors as well as the others, and that 
they are far more indiscriminating than the majority of insect- 
eaters” (p. 316). ‘But Mr. Marshall’s experiments yielded 
plenty of evidence of the positive refusal and acceptance, as it 
were, under protest of Acreine, so that there can be no doubt 
of their distastefulness to this class of enemy” (p. 317). 
Despite this conclusion, the fact remains that these Mantide ate 
more Acreine than they rejected upon trial, and rejected no 
Danaine. It should be noted, furthermore, that many of the 
rejections occurred in the last day or two of the life of the 
various individual mantids when no food whatever was taken. 
Experiments on spiders in the Karkloof (G. A. K. M.), pp. 319-322. 
Results of experiments on spiders and the earlier experiments on 
Mantide: one probable meaning of tenacity of life in distasteful 
insects (G. A. K. M.) pp. 322-325, (E. B. P.) pp. 325-328. 
“Experiments have convinced me that both spiders and mantises 
have no appreciation of warning colors” (p. 322). ‘It is quite 
probable . . . . that certain species of spiders, together with 
mantides and other predaceous insects, will be found among the 
chief, perhaps the chief, non-parasitic enemies of aposematic 
insects” (p. 327).

Burmah and Ceylon, Calcutta, 1882-83. 
“Mr. de Niceville has experimented with the carnivorous Mantis 
on many of the butterflies believed to be offensive to birds, and 
he has found A. viole is the only butterfly which all the species 
of .antis he has experimented with refuse to eat’ (p. 318). 
This is all there is on the experiments.

A larva of the ant-lion (Myrmeleon) which had been fed only 
upon flies and caterpillars for a long time, afterwards rejected 
ants. <A Clerus formicarius ate every Adalia bipunctata which 
got into its cage.

Pterostichus lucublandus was tested with numerous specimens of 
Corimelena pulicaria, Cosmopepla carnifex, Lygus pratensis, 
and one Serica vespertina, all of which were eaten. Staphy- 
linide were tested with the Corimelena, Lygus, Cosmopepla and 
cutworms with same result.
