the very same localities; (3°) that in eight cases the mimickers were 
known to be very much scarcer than the species which they copy ; 
(4°) that in five cases where the Danais or Acrcva presents local forms 
or merely slight varieties, even these were mimicked by individuals of 
the imitating species ; (5 °) that in three cases where the sexes of the 
insect mimicked differed strikingly from each other, the sexes of the 
mimicker presented corresponding differences ; and (6°) that in four 
cases observed by me in life it was next to impossible to distinguish 
the mimicker from the species which it mimicked. It must be remem- 
bered that these extraordinary likenesses are not those of general 
colouring and pattern alone, but include outline and form, and extend 
to minute reproduction of prominent markings, however small ; and 
that the deception is often further ensured by following closely the 
kind of flight and mode of resting proper to the species copied.
