  — 
  A 
  brood 
  of 
  some 
  eighteen 
  specimens 
  of 
  this 
  hybrid 
  emerged 
  

   in 
  1892 
  from 
  a 
  crossing 
  obtained 
  by 
  W. 
  H. 
  B. 
  Fletcher 
  in 
  1891. 
  

   Four 
  $ 
  s 
  and 
  eight 
  $ 
  s 
  under 
  examination 
  show 
  distinct 
  sexual 
  

   differences, 
  and 
  the 
  sexual 
  dimorphism 
  is 
  as 
  marked 
  in 
  ground 
  colour, 
  

   amount 
  of 
  speckling, 
  antennae, 
  body, 
  shape 
  of 
  wings, 
  etc., 
  as 
  in 
  the 
  parent 
  

   species. 
  The 
  imagines 
  themselves 
  may 
  be 
  said 
  to 
  be 
  excellent 
  inter- 
  

   mediates 
  between 
  the 
  parent 
  species, 
  the 
  ground 
  colour 
  approximating 
  

   rather 
  to 
  the 
  whiter 
  tint 
  of 
  pusaria, 
  the 
  more 
  abundant 
  speckling 
  

   directly 
  indicating 
  exanthemaria, 
  whilst 
  the 
  brownness 
  of 
  the 
  transverse 
  

   lines 
  also 
  points 
  in 
  the 
  direction 
  of 
  the 
  latter. 
  There 
  is 
  some 
  variation 
  

   in 
  the 
  markings 
  of 
  the 
  specimens 
  inter 
  se, 
  one 
  $ 
  and 
  seven 
  2 
  s 
  having 
  

   a 
  very 
  distinct 
  angulation 
  in 
  the 
  middle 
  line 
  at 
  the 
  position 
  of 
  the 
  

   discoidal 
  lunule, 
  two 
  $ 
  s 
  and 
  one 
  $ 
  showing 
  the 
  two 
  basal 
  lines 
  united, 
  

   as 
  in 
  C. 
  pusaria 
  ab. 
  rotundaria, 
  and 
  one 
  $ 
  only 
  having 
  the 
  three 
  

   transverse 
  lines 
  more 
  or 
  less 
  typical 
  of 
  the 
  parent 
  species.

  Oporabia 
  hybrids. 
  — 
  Allen 
  asserts 
  (Ent. 
  Bee, 
  

   xviii., 
  pp. 
  85-89) 
  the 
  specific 
  distinctness 
  of 
  Oporabia 
  christyi. 
  He 
  

   says 
  that 
  it 
  breeds 
  perfectly 
  true. 
  At 
  the 
  same 
  time 
  he 
  says 
  it 
  pairs 
  

   readily 
  with 
  0. 
  dilutata 
  in 
  confinement, 
  and 
  the 
  progeny 
  is 
  fertile. 
  He 
  

   has 
  obtained 
  pairings 
  of 
  $ 
  christyi 
  x 
  $ 
  dilutata, 
  and 
  $ 
  dilutata 
  x 
  $ 
  

   christyi. 
  Some 
  of 
  the 
  offspring 
  might 
  pass 
  for 
  0. 
  christyi, 
  and 
  some 
  

   for 
  0. 
  dilutata, 
  but 
  most 
  of 
  them 
  partake 
  of 
  the 
  external 
  character 
  of 
  

   both. 
  They 
  exhibit 
  all 
  the 
  tendencies 
  to 
  variation 
  which 
  occur 
  in 
  the 
  

   two 
  species. 
  He 
  does 
  not 
  think 
  that 
  0. 
  dilutata 
  and 
  0. 
  christyi 
  ever 
  

   pair 
  in 
  a 
  state 
  of 
  nature. 
  In 
  the 
  few 
  doubtful 
  specimens 
  taken 
  at 
  large, 
  

   the 
  difficulty 
  of 
  determining 
  the 
  species 
  has 
  seemed 
  to 
  be 
  due 
  merely 
  

   to 
  bad 
  condition. 
  A 
  few 
  attempts 
  to 
  pair 
  0. 
  christyi 
  and 
  0. 
  autumnata 
  

   have 
  failed.
