 Dark colour and habits of concealment are strongly protective. 



Epeira diadcma and Tcgenaria dmnesfica were chiefly employed in some of 

 the experiments (E. B. P.), but any common Spiders which could be found 

 were offered to the Lizards and Frogs. lu appearance, and especially in 

 their rapid retreat into concealment, the Spiders are difficult to capture, 

 especially when it has been shown that the enemies do not like the web in 

 their mouths. 



Myeiapoda. 

 lulus terrestris 



The dai-k colour and habits of concealment are strongly protective, but it also 

 possesses a very unpleasant odour. 



Lithobius forficatus 



The brownish orange colour, and especially habits of concealment, are strongly 

 protective : inodorous. 



Ortiioptera. 

 Forficula auricularia 



Probably this common species of Earwig was always employed. The colour 

 and habits of concealment are strongly protective. The pincers may perhaps, 

 in some cases, act as " terrifying" structures. The insect has a very disagree- 

 able smell. 



Periplaneta orientalis 



The colour, rapid movements, and habits of concealment are strongly protec- 

 tive, but the insects also emit a very unpleasant odour. 



Becticus verucivorus. 



A large green grasshopper, with brown spots on the fore wings. 

 concealed, and evidently a very powerful hopper.

 Chrysofpa, perla 



Probably this common species was employed. Its gi-een colour protects the 

 insect among the leaves in which it lives, but it can also emit a peculiarly 

 unpleasant odour.
