﻿Lejyidoptera 
  collected 
  in 
  Madeira. 
  203 
  

  

  especially 
  in 
  the 
  district 
  above 
  Funchal, 
  called 
  " 
  the 
  

   Mount." 
  It 
  was 
  described 
  by 
  Fabricius 
  in 
  1775 
  from 
  

   Madeiran 
  specimens. 
  

  

  Xiphia 
  is 
  now 
  so 
  well 
  known 
  that 
  it 
  is 
  quite 
  unnecessary 
  

   to 
  redescribe 
  it. 
  There 
  is 
  no 
  doubt 
  in 
  my 
  own 
  mind 
  that 
  it 
  

   should 
  retain 
  its 
  specific 
  rank, 
  but 
  the 
  present 
  seems 
  to 
  

   be 
  a 
  good 
  opportunity 
  of 
  settling 
  the 
  position 
  of 
  var. 
  

   xiphioides, 
  which 
  insect 
  is 
  certainly 
  a 
  form 
  of 
  cegeria, 
  

   and 
  not 
  of 
  xiphia. 
  

  

  The 
  whole 
  of 
  the 
  markings 
  of 
  cegeria 
  are 
  carefully 
  

   reproduced 
  in 
  var. 
  xiphioides, 
  the 
  difference 
  being 
  that 
  

   the 
  Canary 
  form 
  is 
  much 
  darker 
  and 
  richer 
  in 
  colours 
  

   in 
  all 
  respects, 
  and 
  that 
  the 
  spots 
  are 
  somewhat 
  reduced 
  

   in 
  size. 
  If 
  in 
  our 
  own 
  common 
  form 
  of 
  cegeria 
  {cBgerides 
  

   of 
  Staudinger's 
  Catalogue) 
  the 
  olivaceous 
  brown 
  was 
  

   replaced 
  by 
  a 
  deep 
  rich 
  umber 
  and 
  the 
  pale 
  spots 
  altered 
  

   to 
  a 
  pale 
  sienna, 
  we 
  should 
  have 
  var. 
  xijjhioides 
  exactly, 
  

   only 
  perhaps 
  a 
  trifle 
  smaller 
  than 
  the 
  average 
  size 
  of 
  the 
  

   Canary 
  insect. 
  The 
  same 
  remarks 
  apply 
  to 
  the 
  under 
  

   side, 
  the 
  only 
  difference 
  being 
  great 
  intensification 
  and 
  

   richness 
  in 
  colour. 
  

  

  Between 
  the 
  Madeiran 
  xiphia 
  and 
  these 
  two 
  insects 
  

   there 
  appear 
  to 
  me 
  to 
  be 
  constant 
  differences. 
  The 
  two 
  

   spots 
  in 
  the 
  median 
  portion 
  of 
  the 
  wing 
  are 
  quite 
  want- 
  

   ing 
  in 
  the 
  former 
  ; 
  the 
  whole 
  of 
  the 
  posterior 
  margin 
  is 
  

   entirely 
  dark, 
  there 
  being 
  no 
  pale 
  border 
  or 
  pale 
  spot 
  

   therein 
  ; 
  and 
  the 
  streak 
  or 
  short 
  dash 
  on 
  the 
  secondaries 
  

   within 
  the 
  ocellated 
  row 
  is 
  much 
  increased 
  in 
  size, 
  often 
  

   extending 
  three-quarters 
  across 
  the 
  wing. 
  Furthermore, 
  

   the 
  (? 
  is 
  adorned 
  with 
  a 
  patch 
  of 
  long 
  downy 
  scales 
  in 
  

   the 
  primaries, 
  extending 
  all 
  over 
  the 
  discal 
  cell, 
  smoothed 
  

   down 
  from 
  the 
  costal 
  towards 
  the 
  inner 
  margin, 
  and 
  

   terminating 
  in 
  a 
  blackish 
  line 
  just 
  below 
  the 
  said 
  cell. 
  

   The 
  under 
  side 
  is 
  rather 
  variable 
  as 
  to 
  the 
  hind 
  wings, 
  

   the 
  general 
  hue 
  being 
  much 
  richer, 
  with 
  an 
  absence 
  of 
  

   markings 
  (a 
  sort 
  of 
  obsoletion) 
  and 
  uniformity 
  of 
  colour 
  ; 
  

   this, 
  however, 
  is 
  sometimes 
  varied 
  by 
  great 
  contrast, 
  

   from 
  rich 
  red-brown 
  to 
  grey 
  and 
  white, 
  this 
  being 
  caused 
  

   by 
  the 
  great 
  intensification 
  of 
  the 
  hue 
  of 
  the 
  usual 
  

   pattern. 
  Added 
  to 
  this, 
  the 
  Madeiran 
  species 
  is 
  

   uniformly 
  much 
  larger 
  than 
  either 
  cegeria 
  or 
  var. 
  

   xiphioides 
  ; 
  the 
  smallest 
  xiphia 
  is 
  decidedly 
  larger 
  than 
  

   the 
  largest 
  var. 
  xiphioides 
  I 
  have 
  ever 
  seen, 
  whilst 
  the 
  

   latter 
  is 
  larger 
  than 
  the 
  common 
  European 
  species.
