  As 
  explained 
  on 
  page 
  3, 
  this 
  is 
  considered 
  to 
  be 
  a 
  distinct 
  species 
  

   from 
  ampullata 
  Buckton. 
  I 
  take 
  pleasure 
  in 
  naming 
  it 
  after 
  Laing, 
  

   who 
  first 
  called 
  my 
  attention 
  to 
  the 
  differences. 
  I 
  learn 
  from 
  corre- 
  

   spondence 
  with 
  Professor 
  Oestlund 
  that 
  his 
  1887 
  description 
  of 
  am- 
  

   pullata 
  Buckton 
  is 
  in 
  reality 
  of 
  this 
  new 
  species. 
  Van 
  der 
  Goot's 
  

   1915 
  description 
  is 
  plainly 
  so. 
  I 
  can 
  not 
  tell 
  from 
  William's 
  1910 
  

   description 
  of 
  "ampullata 
  Buckt?" 
  what 
  he 
  had, 
  and 
  his 
  specimens 
  

   seem 
  to 
  be 
  lost, 
  but 
  it 
  was 
  very 
  probably 
  not 
  a?npullata 
  Buckton, 
  

   since 
  this 
  is 
  not 
  known 
  from 
  this 
  continent. 
  In 
  view 
  of 
  the 
  rather 
  

   common 
  and 
  widespread 
  distribution 
  of 
  this 
  species 
  it 
  is 
  very 
  probable 
  

   that 
  all 
  the 
  references 
  in 
  literature 
  to 
  ampullata 
  Buckton, 
  except 
  

   those 
  which 
  simply 
  catalogue 
  the 
  original 
  description, 
  refer 
  to 
  this 
  

   species 
  and 
  they 
  are 
  so 
  treated 
  here. 
  I 
  have 
  selected 
  as 
  cotypes 
  cer- 
  

   tain 
  specimens 
  from 
  Dr. 
  E. 
  M. 
  Patch, 
  of 
  Orono, 
  Me., 
  as 
  this 
  is 
  the 
  

   only 
  collection 
  I 
  have 
  which 
  has 
  both 
  alate 
  and 
  apterous 
  forms 
  in 
  

   the 
  same 
  collection.

  colored,

  than 
  width 
  of

  III 
  with

  with 
  no 
  secondary 
  sensoria.
