1887.] VALUE OF COLOUR AND MARKINGS IN INSECTS.

{continued). 



Experiments. 



A. Weismann, 



using 

 Lacerta viridis. 



E. B. Poulton, 



using three species 



of Lizards and 



Hyla. 



Avoided by L. vi. 

 ridis. 



Eaten by very hun- 

 gry L. rnundis, 

 and, I believe, by 

 L. viridis, and yet 

 evidently dishked 

 by all. 



How far support given to 

 Wallace's suggestion, 

 that brilliant and conspicu- 

 ous lar\ae would be 

 refused by some at least 

 of their enemies. 



Strong support. 



How far support given to 



Poulton"s suggestion, 



that a limit to the success of 



this method of defence 



would result from the 



hvmger which the success 



itself tends to produce. 



No evidence. 



Strong support. 



L. muralis, when 

 hungry, bit the 

 larva, retaining it 

 for a long time, 

 but in the end re- 

 jected it, and much 

 irritated by hairs. 



Entirely disregard- 

 ed by L. viridis 

 until after another 

 similar but pala- 

 table larva had 

 been introduced ; 

 then tasted, but 

 rejected. 



Devoured by L. vi- 

 ridis, "but not 

 exactly rehshed." 



Seized and relin- 

 quished by hun- 

 gry L. muralis, 

 Probably eaten 

 later ; but insuf- 

 ficient evidence. 



Strong support in Jenner Weir"s 

 observation ; and Butlers 

 shows that the hairs are much 

 disUked. 



Strong support. 



Strong support, on the whole. 

 It is impossible to decide 

 whether the Sky-Lark was 

 killed by the larva;. If so, it 

 strongly opposes the theory of 

 any instinctive knowledge. 



Strong support. 



No evidence, for the Missel- 

 Thrush appeared to relish the 

 lar\se. 



It is certainly a support to the 

 suggestion tliat a Lizard when 

 hungry enough should make 

 such a determined attempt to 

 eat the larva, which it evi- 

 dently disliked. 



It is certainly a support to the 

 suggestion that a Lizard when 

 hungry enough should make 

 such a determined attempt to 

 eat the larva. 



Support. 



Strong support. Eaten, al- 

 though unpleasant in some 

 way.
