  allied, 
  but 
  also 
  between 
  most 
  distantly 
  related, 
  species, 
  even 
  those 
  

   belonging 
  to 
  different 
  superfamilies, 
  between 
  which 
  it 
  would 
  be 
  idle 
  to 
  

   suppose 
  that 
  hybrid 
  progeny 
  could 
  result.

  The 
  close 
  

   alliance 
  of 
  some 
  of 
  these 
  Melitasas 
  makes 
  one 
  feel 
  that 
  one 
  would 
  like 
  to 
  

   have 
  seen 
  the 
  paired 
  specimens. 
  On 
  the 
  whole, 
  however, 
  one 
  is 
  forced 
  to 
  

   the 
  conclusion 
  that 
  pairing 
  between 
  very 
  closely 
  allied 
  species 
  in 
  nature 
  

   is 
  exceedingly 
  rare.

  One 
  of 
  the 
  most 
  remarkable 
  records 
  is 
  that 
  made 
  (Soc. 
  Ent., 
  xviii., 
  p. 
  121) 
  

   by 
  Doleschall, 
  in 
  which 
  he 
  makes 
  the 
  astounding 
  statement 
  that, 
  in 
  August 
  ls 
  ( 
  ,'l. 
  he 
  

   captured 
  a 
  j 
  Syntomis 
  phegea 
  and 
  ? 
  Anthrocera 
  purpuralis, 
  in 
  cup., 
  kept 
  the 
  pair 
  

   alive 
  and 
  obtained 
  ova, 
  from 
  which 
  larvae 
  in 
  due 
  course 
  resulted 
  : 
  that 
  finally 
  he 
  

   bred 
  a 
  d 
  imago 
  which 
  differed 
  in 
  no 
  way 
  from 
  the 
  j 
  of 
  S. 
  phegea. 
  We 
  have 
  

   already 
  criticised 
  (Ent. 
  Rec, 
  xiv., 
  p. 
  353) 
  this 
  record, 
  and 
  pointed 
  out 
  the 
  only 
  

   possible 
  explanation, 
  viz., 
  that 
  the 
  sexes 
  were 
  the 
  opposite 
  of 
  those 
  named, 
  the 
  

   phegea 
  being 
  ? 
  , 
  and 
  further, 
  that 
  it 
  had 
  already 
  been 
  fertilised 
  by 
  a 
  & 
  of 
  its 
  own 
  

   species. 
  The 
  fertilisation 
  of 
  a 
  ? 
  Anthrororid 
  by 
  a 
  <J 
  Aretiid. 
  belonging 
  as 
  they 
  

   do 
  to 
  entirely 
  different 
  lepidopterological 
  stirpes, 
  appears 
  to 
  us 
  to 
  be 
  absolutely 
  

   impossible.
