  had 
  the 
  effect 
  of 
  supplanting 
  his 
  

   original 
  descriptions, 
  and 
  served 
  rather 
  to 
  obscure 
  the 
  

   classification 
  than 
  to 
  render 
  it 
  more 
  correct 
  or 
  more 
  easy 
  

   of 
  comprehension. 
  Cryptolechia 
  straminella 
  having 
  been 
  

   described 
  originally 
  as 
  the 
  type 
  of 
  the 
  genus 
  (Hand. 
  

   Kongl. 
  Svensk. 
  Vet.-Ak., 
  1852, 
  107), 
  he 
  subsequently 
  

   recharacterised 
  the 
  same 
  genus 
  in 
  an 
  expanded 
  form, 
  

   making 
  Depresmria 
  (Volucra) 
  flava, 
  from 
  South 
  America, 
  

   the 
  typical 
  species 
  (Lin. 
  Ent., 
  IX., 
  353 
  — 
  5 
  (1854) 
  ), 
  in- 
  

   correctly 
  using 
  the 
  expression 
  " 
  vense 
  simplices," 
  whereas 
  

   veins 
  7 
  and 
  8 
  of 
  the 
  fore 
  wings 
  in 
  that 
  species 
  are 
  from 
  

   a 
  common 
  stem, 
  and, 
  in 
  fact, 
  the 
  species 
  agrees 
  in 
  all 
  

   points 
  with 
  straminella. 
  

  

  In 
  the 
  Horse 
  Soc. 
  Ent. 
  Boss., 
  XIII., 
  259 
  (1877), 
  he 
  

   removed 
  C. 
  straminella 
  to 
  Machimia, 
  retaining 
  y?a?;a 
  in 
  

   Cryptolechia 
  in 
  defiance 
  of 
  the 
  fact 
  that 
  their 
  characters 
  

   are 
  identical, 
  and 
  differ 
  from 
  tentoriferella, 
  Clem., 
  the 
  

   type 
  of 
  Machimia, 
  in 
  the 
  remoteness, 
  at 
  its 
  origin, 
  of 
  

   vein 
  2 
  from 
  vein 
  3, 
  which 
  arises 
  at 
  the 
  lower 
  angle 
  of 
  

   the 
  cell 
  of 
  the 
  fore 
  wings. 
  

  

  With 
  regard 
  to 
  Stenoma, 
  which 
  was 
  described 
  by 
  

   Zeller 
  (Isis, 
  1839, 
  195), 
  and 
  included 
  griseanum, 
  litura, 
  

   and 
  bicolor, 
  alike 
  in 
  structure 
  and 
  neuration 
  ; 
  in 
  the 
  

   Lin. 
  Ent., 
  IX., 
  391 
  — 
  3 
  (1854), 
  he 
  identified 
  ^mmm<m 
  as 
  

   walchiana, 
  Cram., 
  and 
  founded 
  the 
  genus 
  Antceotricha 
  

   for 
  its 
  reception, 
  together 
  with 
  some 
  allied 
  species. 
  He 
  

   then 
  removed 
  litura 
  and 
  bicolor 
  to 
  Cryptolechia 
  (pre- 
  

   sumably 
  Cryptolechia 
  No. 
  2), 
  from 
  which 
  they 
  differ, 
  as 
  

   from 
  No. 
  1, 
  in 
  having 
  veins 
  7 
  and 
  8 
  of 
  the 
  fore 
  wings, 
  

   as 
  also 
  6 
  and 
  7 
  of 
  the 
  hind 
  wings, 
  separate, 
  corre- 
  

   sponding 
  therefore 
  to 
  his 
  statement 
  '' 
  venm 
  simplices,'' 
  

   but 
  not 
  to 
  his 
  selected 
  type. 
  In 
  the 
  Horse 
  Soc. 
  Ent. 
  

   Eoss., 
  XIII., 
  258-261 
  (1877), 
  he 
  still 
  further 
  extended 
  

   his 
  genus 
  Cryptolechia, 
  including 
  many 
  modified 
  forms 
  

   as 
  subgenera. 
  He 
  here 
  resuscitated 
  Stenoma 
  (of 
  which, 
  

   as 
  I 
  have 
  shown, 
  the 
  original 
  type 
  was 
  griseanum 
  = 
  

   ivalchiana), 
  and, 
  having 
  got 
  rid 
  of 
  the 
  other 
  species 
  

   placed 
  in 
  it 
  in 
  the 
  first 
  instance, 
  he 
  left 
  litura 
  as 
  the 
  type 
  

   at 
  the 
  head 
  of 
  his 
  list, 
  placing 
  bicolor 
  in 
  a 
  different 
  sub- 
  

   section, 
  and 
  ormiiing 
  griseanum 
  altogether, 
  although 
  the 
  

   three 
  are 
  identical 
  in 
  structure. 
  

  

  In 
  pointing 
  out 
  these 
  inconsistencies 
  I 
  have 
  had 
  the 
  

   great 
  advantage 
  of 
  possessing 
  nearly 
  the 
  whole 
  series 
  of 
  

   Zeller's 
  generic 
  types, 
  in 
  many 
  cases 
  the 
  actual 
  speci-
