  of 
  Fitcli 
  (Fig. 
  0) 
  that 
  I 
  refer 
  it 
  to 
  tliat 
  species, 
  tlioiigli 
  with 
  a 
  doubt. 
  

  

  This 
  is 
  probablj^ 
  also 
  the 
  parasite 
  referred 
  to 
  by 
  Mr. 
  Herrick. 
  

  

  Itissliiiiiiigbhick; 
  the 
  head 
  is 
  finely 
  punctured, 
  rounded, 
  and 
  slightly 
  

  

  broader 
  than 
  long, 
  being 
  about 
  as 
  wide 
  as 
  the 
  thorax. 
  The 
  antenna) 
  

  

  are 
  about 
  as 
  Ion 
  gas 
  the 
  head 
  and 
  thorax 
  ; 
  they 
  

   are 
  slender, 
  but 
  apparently 
  a 
  little 
  stouter 
  

   than 
  in 
  P. 
  error 
  , 
  the 
  penultimate 
  joints 
  being 
  

   a 
  little 
  broader 
  and 
  sqnarer 
  than 
  he 
  repre- 
  

   sents 
  (and 
  they 
  are 
  very 
  different 
  from 
  Platy- 
  

   (jaster

  these 
  joints 
  not 
  being

  but 
  only 
  J

  those 
  just 
  behind 
  it, 
  and 
  it 
  tapers 
  to 
  a 
  

  

  rounded 
  point. 
  The 
  thorax 
  is 
  rounded 
  ovate, 
  but 
  little 
  longer 
  than 
  

   broad, 
  black, 
  Avith 
  the 
  scutelluni 
  high, 
  rounded 
  and 
  pitted. 
  The 
  abdo- 
  

   men 
  is 
  flattened, 
  oval, 
  twice 
  as 
  long 
  as 
  wide, 
  being 
  a 
  little 
  longer 
  than 
  

   the 
  thorax, 
  but 
  not 
  quite 
  so 
  wide. 
  The 
  legs 
  are 
  i)itchy 
  black 
  on 
  the 
  

   femora 
  J 
  the 
  tibice 
  dull 
  reddish-brown, 
  darker 
  towards 
  the 
  end; 
  the 
  tarsi 
  

   are 
  5-jointed, 
  dark 
  brown, 
  hairy, 
  with 
  the 
  baisal 
  joint 
  reddish 
  at 
  the 
  base. 
  

   (Fitch 
  says 
  the 
  legs 
  of 
  P. 
  error 
  are 
  pitchy 
  black; 
  but 
  in 
  the 
  specimen 
  

   before 
  me 
  they 
  have 
  a 
  decided 
  reddish 
  tinge.) 
  The 
  wings 
  are 
  veinless, 
  

   clear 
  transparent, 
  irised. 
  Length 
  1.8 
  millimeters, 
  being 
  a 
  little 
  larger 
  

   than 
  Fitch's 
  P. 
  en^or, 
  which 
  w^as 
  0.05 
  inch 
  long. 
  I 
  am 
  disposed 
  to 
  refer 
  

   this 
  specimen 
  to 
  Fitch's 
  species, 
  but 
  should 
  it 
  be 
  found 
  to 
  be 
  quite 
  dis- 
  

   tinct, 
  it 
  may 
  receive 
  the 
  name 
  Flatygaster 
  herriclcli. 
  It 
  seems 
  to 
  be 
  a 
  

   genuine 
  Flatygaster. 
  

  

  Fitch 
  states 
  that 
  Flatygaster 
  error 
  is 
  seen 
  in 
  company 
  with 
  the 
  wheat 
  

   midge 
  [Diplosis 
  tritici) 
  on 
  the 
  wheat 
  ears 
  in 
  New 
  York, 
  and 
  is 
  very 
  numer- 
  

   ous 
  some 
  years, 
  but 
  he 
  thinks 
  it 
  doubtful 
  whether 
  it 
  preys 
  upon 
  the 
  

   midge. 
  

  

  Having 
  become 
  familiar 
  with 
  the 
  habits 
  of 
  this 
  insect, 
  which 
  can 
  be 
  

   readily 
  observed 
  by 
  farmers, 
  it 
  is 
  not 
  difficult 
  to 
  apply 
  such 
  remedies 
  as 
  

   the 
  experience 
  of 
  wheat 
  raisers 
  of 
  the 
  past 
  century 
  in 
  different 
  parts 
  of 
  

   the 
  wheat 
  region 
  of 
  the 
  United 
  States 
  has 
  nearly 
  universally 
  found 
  

   serviceable. 
  Eemembering 
  that 
  the 
  first 
  brood 
  of 
  flies 
  appears 
  in 
  

   August 
  and 
  continues 
  to 
  hover 
  over 
  the 
  fields 
  until 
  late 
  in 
  September, 
  as 
  

   if 
  waiting 
  for 
  the 
  fall-sown 
  wheat 
  to 
  appear, 
  it 
  is 
  evident 
  that 
  by 
  delay- 
  

   ing 
  the 
  date 
  of 
  sowing 
  until 
  after 
  a 
  frost 
  cold 
  enough 
  to 
  kill 
  the 
  flies, 
  

   the}" 
  may 
  be 
  circumvented; 
  for 
  if 
  the 
  wheat 
  is 
  sown 
  later 
  than 
  the 
  

   20tii 
  of 
  September 
  in 
  nearly 
  all 
  the 
  Middle 
  and 
  Northern 
  States, 
  the 
  

   early 
  frosts 
  will 
  destroy 
  these 
  delicate 
  insects. 
  Late 
  sowing, 
  then, 
  is 
  the 
  

   most 
  general, 
  important, 
  and 
  easily 
  applied 
  preventive 
  remedy.
