MIMICRY, WITH EXAMPLES 



Ul 



real structural characters show that 

 they belong to distinct sub-f amilie.= 



It is the common impres- 

 sion among naturahsts that 

 the resemblance of these 

 two species has been 

 brought about by 

 natural selection. 

 For this reason I 

 have summed up 

 the leading facts 

 upon which this 

 assumption is 

 based, espe- 

 cially as there 

 has been 

 some skep- 

 ticism re- 

 garding the 

 action of 

 selection in 

 bringing 

 about the 

 apparent mim- 

 icry here wit- 

 nessed. In 

 order to pre- 

 sent these facts 

 in a readily appre- 

 ciable form, brief 

 sketches of the salient 

 points are given of each 

 their respective life histories, 

 placed side by side: 



Monarch 

 Adult resembling Viceroy; visits flow- 

 ers in same company with Viceroy. 

 Male provided with black pouch on 

 hind wings containing scent scales 

 or androconia.

 fly on the leaf of heart- 

 shaped willow.
