OF OTHER Classes (continued). 



Aphis hedercB freely ecaten by 

 young Hylm. 



Eaten greedily and in almost 

 any numbers by Lizards of 

 all the species and by Hyla. 

 The latter was especially keen 

 in capturing them, but did 

 not much cure for the larvte, 

 which, witli the pup;B, were 

 eaten in large numbers by the 

 LiEards. 



Keenly relished by the Frogs... 



Aphides? sp., eaten 

 by i. viridis, L.agi- 

 lis, and Z. vivipara. 

 Oil another occa- 

 sion hardly noticed 

 by the Lizards. 



Refused by the Li- 

 zards after tasting. 



Eaten witli relish by 

 all the species of 

 Lizards, and in 

 very large num- 

 bers. The larva' 

 and pupre also 

 eaten. 



Eaten voraciously 

 by all the Lizards. 



The males eaten in large num- 

 bers by young Hyke. 



Eaten by L. viridis 



Eaten by all the Lizards . 



Eaten by all the Lizards , 



Eaten bv L. mt/ra/is 



Eaten by 



viridis. 



Lacerta 



Eaten witli avidity 

 by the Lizards. 



Other observers. 



Bearing upon Wallace's 

 converse suggestion. 



Eaten by L. viridis 

 {A. G. Butler). 



Erista lis vulpinus 

 eaten in large 

 numbers by L. vi- 

 ridis {A. G. But- 

 ler). 



Conclusion for Aphides? sp. : 

 probably as above: the Lizards 

 evidently di^like the taste, but 

 will eat the insects when hun- 

 gry. The treatment of Aphis 

 hcdcreg supports conclusions. 



The unpleasant qualities evi- 

 dently a defence in this case. 



Strong support.

Well known to be 

 the favourite food 

 of Pliea>-ants &c. 

 In this case the 



species is t'ormivu

Strong support. 



Support. It woidd be exceed- 

 ingly interesting to compare 

 the behaviour of Lizards and 

 birds towards the male and 

 female insects.
