{continued). 



Experimental evidence.

OF OTHER Classes {continued). 



Aphis hederm freely eaten by 

 young HylcB, 



Eaten greedily and in almost 

 any numbers by Lizards ol 

 all tbe species and by Hyla. 

 The latter was especially keen 

 in capturing them, but did 

 not much care for the larvae, 

 which, with the pupne, were 

 eaten in large numbers by the 

 Lizards. 



Keenly relished by the Frogs... 



Aphides? sp., eaten 

 by L. viridis, L. luji- 

 lis, and Z. vivipara. 

 On another occa- 

 sion hardly noticed 

 by the Lizards. 



Refused by the Li- 

 zards after tasting. 



Eaten with relish by 

 all the species of 

 Lizards, and in 

 very large num- 

 bers. The larva' 

 and pupte also 

 eaten. 



Eaten voraciously 

 by all the Lizards. 



Eaten by Lacerta 

 viridis. 



Other observers. 



Eaten by L. viridis 

 {A. G. Butler). 



Eristalis vulpinus 

 eaten in large 

 numbers by L. vi- 

 ridis {A. G. But- 

 ler). 



Bearing upon Wallace's 

 converse suggestion. 



Conclusion for Aphides? sp. : 

 probably as above: the Lizards 

 evidently dislike the taste, but 

 will eat the insects when hun- 

 gry. The treatment of Aphis 

 hederm supports conclusions. 



The unpleasant qualities evi- 

 dently a defence m this case.

The males eaten in large num- 

 bers by young Hylce. 



SupiDort. It would be exceed- 

 ingly interesting to compare 

 the behaviour of Lizards and 

 birds towards the male and 

 female insects.
