  The 
  A. 
  bipunctidactyla 
  in 
  the 
  Frey 
  collection 
  are 
  particularly 
  inter- 
  

   esting. 
  One 
  tiny 
  example 
  is 
  only 
  about 
  13mm. 
  across 
  =

   n. 
  ab. 
  ; 
  most 
  of 
  the 
  examples 
  are 
  strikingly 
  brown, 
  especially 
  along 
  

   the 
  inner 
  margin 
  of 
  the 
  forewing, 
  whilst 
  one 
  specimen 
  has 
  the 
  whole 
  

   of 
  the 
  fore 
  wings 
  of 
  a 
  brown 
  tint 
  ; 
  the 
  transverse 
  lobal 
  line 
  is, 
  in 
  this 
  

   example, 
  fairly 
  well-developed, 
  less 
  so, 
  however, 
  than 
  in 
  an 
  example 
  

   from 
  Glogau. 
  The 
  costal 
  area 
  of 
  one 
  Frankfurt 
  example, 
  and 
  of 
  

   three 
  from 
  Zurich, 
  is 
  particularly 
  dark 
  ; 
  the 
  former 
  is 
  also 
  particu- 
  

   larly 
  well 
  marked 
  with 
  black 
  scales, 
  especially 
  in 
  the 
  upper 
  lobe 
  ; 
  

   the 
  white 
  scaling, 
  too, 
  is 
  conspicuous, 
  and 
  the 
  costa 
  towards 
  the 
  base 
  

   is 
  speckled 
  with 
  white, 
  reminding 
  one 
  of 
  the 
  same 
  character 
  in 
  

   Amblyptilia 
  cosmodactyla.

  says 
  the

  feeds 
  openly,

   what 
  marks 
  it 
  as 
  not 
  even 
  a 
  Stenoptilia 
  is 
  tbe 
  pupa, 
  which 
  is 
  " 
  brown

  covered 
  

   with 
  numerous

  It 
  might 
  even 
  be 
  Alucita

  Milliere 
  says 
  that 
  

   millieridactylus 
  is 
  a 
  variety 
  of 
  his 
  plagiodactylus, 
  and 
  is 
  described 
  from 
  a 
  single 
  

   specimen 
  taken 
  by 
  Milliere
