Greedily devoured 

 by the birds. 



Eaten at once by L. muralis, and 

 evidently relished. Eaten in 

 large numbers by the Hyla ; 

 although individuals would 

 refuse them, yet they were 

 generally taken ; and some- 

 times one Frog would take as 

 many as five, one after the 

 other. 



Eaten at once by L. muralis. 

 Evidently relished. 



Eaten at once and with appa-

Strong support, as in the last 

 species.

Support, for it certainly evades 



its enemies. 



Support, 



Support, for the insect clearly 

 avoids its enemies. But the 

 protection does not seem to 

 be very perfect. 



Strong support.
