  I 
  use 
  the 
  above 
  scientific 
  name 
  in 
  this 
  place 
  without 
  having 
  entered 
  into 
  the 
  

   question 
  of 
  synonomy 
  — 
  a 
  question 
  for 
  the 
  determination 
  of 
  which 
  I 
  have 
  no 
  

   adequate 
  material. 
  Domitia 
  is 
  the 
  name 
  that 
  has 
  been 
  used 
  hitherto 
  in 
  

   most 
  American 
  descriptive 
  papers. 
  Dr 
  Hagen 
  regarded 
  ten 
  era 
  and 
  

   tenuicincta 
  Say, 
  chlora 
  Rambur, 
  metella 
  Selys, 
  and 
  iri 
  s 
  Hagen, 
  

   as 
  synonyms 
  of 
  domitia. 
  Forms 
  like 
  those 
  occurring 
  in 
  New 
  York 
  state 
  

   were 
  described 
  by 
  Say 
  (1839) 
  under 
  two 
  names, 
  tenuicincta 
  (^\ 
  and 
  

   tenera 
  ($)• 
  Should 
  these 
  be 
  ranked 
  as 
  a 
  species 
  distinct 
  from 
  domitia 
  

   the 
  latter 
  name, 
  having 
  precedence 
  of 
  position 
  in 
  Say's 
  list, 
  would 
  be 
  the 
  name 
  

   for 
  the 
  species.

  This 
  is 
  a 
  pretty, 
  little 
  brown 
  species, 
  vi^ith 
  amber 
  tinted 
  wings. 
  It 
  is 
  

   apparently 
  not 
  common 
  in 
  New 
  York 
  state, 
  having 
  been 
  taken 
  as 
  yet 
  

   only 
  in 
  the 
  vicinity 
  of 
  New 
  York 
  city. 
  I 
  studied 
  the 
  species 
  in 
  Gales- 
  

   burg 
  111., 
  in 
  1895, 
  and 
  there 
  worked 
  out 
  its 
  Hfe 
  history. 
  

  

  It 
  appears 
  on 
  the 
  wing 
  about 
  the 
  end 
  of 
  May, 
  and 
  flies 
  through 
  June. 
  

   Its 
  flight 
  is 
  rather 
  weak, 
  and 
  a 
  bit 
  clumsy 
  and 
  slow. 
  When 
  over 
  water 
  

   it 
  habitually 
  avoids 
  the 
  altitude 
  of 
  the 
  larger 
  and 
  stronger 
  species, 
  keep- 
  

   ing 
  down 
  nearer 
  the 
  surface. 
  It 
  is 
  very 
  sensitive 
  to 
  cloudiness 
  and 
  

   moisture, 
  being 
  seldom 
  seen 
  in 
  flight 
  except 
  when 
  the 
  sun 
  is 
  shining. 
  

  

  The 
  female 
  is 
  sometimes 
  held 
  by 
  the 
  male 
  while 
  ovipositing, 
  but 
  I 
  

   have 
  seen 
  her 
  oftener 
  unattended, 
  dropping 
  her 
  eggs 
  on 
  bits 
  of 
  floating 
  

   dead 
  pond 
  scum 
  by 
  many 
  successive 
  dips 
  made 
  at 
  very 
  nearly 
  the 
  same 
  

   spot. 
  When 
  a 
  female 
  was 
  taken 
  in 
  hand 
  and 
  " 
  dipped 
  " 
  to 
  the 
  surface 
  

   of 
  water 
  in 
  a 
  tumbler, 
  lo 
  to 
  20 
  eggs 
  were 
  liberated 
  by 
  her 
  at 
  each 
  de- 
  

   scent.
