   [There 
  appears 
  to 
  us 
  to 
  be 
  little 
  doubt, 
  from 
  the 
  evidence 
  offered 
  by 
  Schiffer- 
  

   muller's 
  description 
  of 
  calodactyla 
  , 
  and 
  Hiibner's 
  figure 
  of 
  the 
  same, 
  that 
  both 
  are 
  

   to 
  be 
  referred 
  to 
  this 
  species. 
  Certain 
  it 
  is 
  that, 
  in 
  both 
  cases, 
  they 
  are 
  Platyptilias, 
  

   with 
  which 
  Hiibner, 
  in 
  the 
  Verzeichniss, 
  p. 
  429, 
  places 
  them, 
  and 
  that 
  both 
  are 
  

   the 
  same 
  species. 
  In 
  addition, 
  Charpentier 
  states 
  that 
  they 
  agree 
  (see 
  anted, 
  p. 
  76), 
  

   and 
  that 
  gonodactyla, 
  Schiff., 
  is 
  only 
  a 
  worn 
  calodactyla, 
  Schiff. 
  (anted, 
  p. 
  77), 
  a 
  mis- 
  

   take 
  that 
  might 
  readily 
  occur, 
  but 
  which 
  shows 
  also 
  that 
  both 
  are 
  Platyptilias. 
  

   Zeller's 
  own 
  opinion 
  (Isis, 
  1841. 
  p. 
  879), 
  that 
  "hitherto 
  he 
  had 
  thought 
  that 
  calo- 
  

   dacti/la, 
  Hb., 
  fig. 
  7, 
  was 
  meant 
  for 
  zetterstedtii, 
  an 
  opinion 
  confirmed 
  by 
  its 
  union 
  

   in 
  the 
  Verzeichniss 
  witb 
  megadaciyla, 
  Hb. 
  (gonodactyla, 
  Schiff.)," 
  is 
  important, 
  but, 
  as 
  

   Hiibner 
  wrongly 
  referred 
  the 
  larva 
  of 
  Amblyptilia 
  cosmodactgla, 
  Hb., 
  to 
  calodactyla, 
  

   B.b.(Raupen,etc, 
  ix., 
  pi. 
  c, 
  figs, 
  a-d), 
  Zeller 
  avers 
  bimself 
  unable 
  to 
  solve 
  the 
  puzzle. 
  

   We 
  cannot 
  understand 
  Zeller's 
  difficulty. 
  Hiibner's 
  error 
  in 
  referring 
  the 
  larva 
  

   and 
  pupa 
  to 
  his 
  calodactyla 
  is 
  evident. 
  An 
  Amblyptiliid 
  larva 
  and 
  pupa 
  cannot 
  

   produce 
  a 
  Platyptiliid 
  imago. 
  Zeller 
  thinks 
  also 
  (Isis, 
  1841, 
  p. 
  879) 
  that 
  Hiibner's 
  

   petradactyla 
  is 
  nearly 
  allied 
  to 
  zetterstedtii. 
  Herrich-Schaffer 
  (Sys. 
  Bearb., 
  v., 
  

   p. 
  368) 
  expressly 
  states 
  that 
  they 
  are 
  identical, 
  and 
  Hofmann 
  agrees 
  (Die 
  deutsch. 
  

   Pteroph., 
  p. 
  194) 
  with 
  this 
  and 
  treats 
  it 
  as 
  the 
  same 
  species. 
  This 
  is 
  our 
  opinion.]
