  The 
  excellent 
  work 
  done 
  by 
  Fernald 
  (Pterophoridae 
  of 
  North 
  

   America, 
  1898) 
  should 
  have 
  carried 
  him 
  farther 
  than 
  a 
  slavish 
  following 
  

   of 
  Meyrick, 
  e.g., 
  comparison 
  of 
  the 
  descriptions 
  of 
  the 
  larvaB 
  of 
  

   kellicotti 
  (p. 
  49), 
  monodactyla 
  (p. 
  51), 
  and 
  paleaceus 
  (p. 
  46) 
  should 
  have 
  

   prevented 
  the 
  species 
  being 
  lumped 
  together 
  in 
  Pterophorus, 
  and 
  other 
  

   details 
  provoke 
  similar 
  criticisms. 
  After 
  denning 
  (p.

  the 
  super- 
  

   family 
  under 
  the

  Dyar's 
  grouping 
  (List 
  of 
  North 
  American 
  Lepidoptera, 
  pp. 
  44 
  et 
  seq.) 
  

   is 
  nothing 
  more 
  than 
  a 
  reproduction 
  of 
  Fernald's 
  work. 
  He 
  has 
  in 
  no 
  

   wise 
  attempted 
  to 
  allow 
  his 
  knowledge 
  of 
  the 
  great 
  differences 
  

   presented 
  by 
  the 
  earlier 
  stages 
  to 
  prevent 
  him 
  from 
  lumping 
  Oidaemato- 
  

   phorus, 
  Wallgrn., 
  and 
  Leioptilus, 
  Wallgrn., 
  into 
  Pterophorus, 
  Geoff., 
  

   which 
  genus, 
  therefore, 
  becomes, 
  in 
  the 
  American 
  lists, 
  a 
  hotch-potch 
  

   of 
  species 
  of 
  widely 
  divergent 
  character. 
  

  

  In 
  Staudinger 
  and 
  Eebel's 
  Catalogue, 
  3rd 
  ed., 
  pp. 
  70 
  et 
  seq., 
  the 
  crudest 
  

   possible 
  divisions 
  are 
  adopted, 
  and 
  all 
  Meyrick's 
  errors, 
  e.g., 
  the 
  use
