 besides which there is a half-tone area at the centre of the wings. 

 They are intioduced for several reasons, as will appear later. 

 Certain butterflies are presumed to be protected from the attack

mimicked by insects which are not thus protected by ill-flavour, 

 in order that they may gain protection by means of a false 

 cloak. The pros and cons of this contention cannot be discussed 

 here, but it is remarkable that many of the insects presenting 

 the type of pattern under consideration belong to what are con- 

 sidered to be protected genera, or to what are considered to be
