SOME PHASES OF PROTECTIVE RESEMBLANCE IN OUR 



SPIDERS. 



By Nathan Banks. 



There is nowadays much discussion concerning the value of 

 mimicry and allied phenomena. Some of this, at least, is 

 based on broad and general statements, which are more or less 

 misleading. Some authors seem to think that most spiders are 

 examples of mimicry or protective resemblance, and if these 

 spiders are found in birds' stomachs it is evidence of the fail- 

 ure of such cryptic resemblance. Both of these ideas are 

 entirely wrong. There are comparatively few cases of pro- 

 tective resemblance among spiders, and the capture by birds 

 of any of these is not of itself any evidence as to the value of 

 the protective device, for the chief enemies of spiders are not 

 birds, but certain insects. 



The subject of cryptic resemblances, as regards our spiders, 

 may be divided into three groups: (i) Protective resem- 

 blance (2), mimicry, and (3) warning coloration. I shall 

 here treat only of certain cases of protective resemblance. 

 The examples of protective resemblance among spiders may 

 be grouped in two classes. One class includes those cases
