﻿The

  could 
  not 
  be 
  classed 
  as 
  var.

  He 
  states 
  that 
  it 
  scarcely 
  differs 
  from 
  fig. 
  128, 
  except 
  in 
  colour, 
  

   which 
  is 
  yellow, 
  more 
  obscure, 
  and 
  with 
  very 
  diffuse 
  strigfe. 
  Both 
  Dr. 
  

   Chapman 
  and 
  I 
  agree 
  with 
  later 
  critics, 
  e.g., 
  Staudinger, 
  in 
  con- 
  

   sidermg 
  r/larearia 
  not 
  a 
  form 
  of 
  atmnaria, 
  but 
  probably 
  a 
  separate 
  

   species. 
  The 
  figure 
  is 
  certainly 
  that 
  of 
  a

  not 
  as 
  Haworth 
  

   says,

  The 
  antennae 
  are 
  not 
  setaceous 
  as 
  in 
  the

  and 
  the 
  

   abdomen 
  is 
  that 
  of 
  a

  . 
  Staudinger 
  even 
  puts 
  it 
  in 
  a 
  separate 
  

   genus, 
  Phosiane, 
  with 
  clathrata 
  and 
  other 
  species 
  to 
  which 
  it 
  bears 
  

   much 
  more 
  resemblance 
  in 
  configuration 
  of 
  wing-form 
  than 
  to 
  

   atoman'a 
  and 
  Fidnnia 
  species 
  generally. 
  

  

  I 
  have 
  since 
  visited 
  the 
  British 
  Museum 
  and 
  find 
  there 
  a 
  long 
  

   series 
  of 
  glarearia, 
  and 
  feel 
  sure 
  that 
  it 
  is 
  a 
  separate 
  species. 
  

  

  The 
  earlier 
  stages 
  of 
  this 
  species 
  have 
  been 
  described 
  by 
  Habick, 
  

   in 
  1901,

  He 
  states 
  that 
  it 
  is 
  smaller, 
  whiter, 
  no 
  powdering, 
  four 
  strigae. 
  

  

  Staudinger 
  takes 
  this 
  figure 
  as 
  a 
  form 
  of 
  our 
  northern 
  species, 
  

   Fidonia 
  carbonaria. 
  I 
  am 
  of 
  opinion, 
  so 
  far, 
  that 
  Haworth 
  was 
  

   right 
  in 
  his 
  statement, 
  and 
  that 
  roseidaria 
  is 
  our 
  British 
  light 
  form 
  

   of 
  female 
  atomaria, 
  which 
  I 
  have 
  taken 
  to 
  be 
  comparatively 
  scarce 
  on 
  

   the 
  continent 
  of 
  Europe.
