   Epicauta

   locusts, 
  especially 
  Locusta, 
  breed 
  in 
  dry 
  deserts, 
  w^hich 
  view 
  has, 
  how- 
  

   ever, 
  lately 
  been 
  modified, 
  and 
  they 
  are 
  now 
  considered 
  to 
  be 
  marsh 
  

   insects. 
  He 
  appeals 
  to 
  the 
  ancient 
  history 
  of 
  Egypt 
  to 
  show 
  that 
  

   this 
  view 
  w^as 
  held 
  there.

   K.K. 
  Pflanzenschutzstation 
  in 
  Wien, 
  March 
  1914, 
  4 
  pp., 
  2 
  figs. 
  

  

  In 
  the 
  spring 
  of 
  1913, 
  samples 
  of 
  wheat 
  were 
  sent 
  to 
  the 
  Station 
  

   from 
  which 
  it 
  is 
  clear 
  that 
  this 
  fly 
  must 
  now 
  be 
  reckoned 
  with 
  as 
  

   a 
  pest 
  of 
  wheat 
  in 
  Austria, 
  and 
  that 
  the 
  damage 
  it 
  does 
  has 
  probably 
  

   been 
  confused 
  hitherto 
  with 
  that 
  caused 
  by 
  the 
  Frit 
  Fly. 
  As 
  the 
  life- 
  

   histories 
  of 
  the 
  two 
  flies 
  and 
  the 
  methods 
  of 
  controlling 
  them 
  differ, 
  

   it 
  is 
  very 
  necessary 
  to 
  distinguish 
  clearly 
  between 
  them. 
  The 
  damage 
  

   done 
  by 
  Hylemyia 
  is 
  noticeable 
  in 
  spring 
  ; 
  it 
  attacks 
  wheat 
  or 
  rye, 
  and 
  

   more 
  rarely 
  barley, 
  while 
  oats 
  are 
  not 
  attacked. 
  The 
  larva, 
  like 
  that 
  

   of 
  the 
  Frit 
  Fly, 
  eats 
  out 
  the 
  heart 
  of 
  the 
  young 
  plant 
  and 
  causes 
  it 
  

   to 
  wither, 
  and 
  one 
  larva 
  wandering 
  from 
  one 
  plant 
  to 
  another 
  may 
  

   attack 
  six 
  or 
  more, 
  so 
  that 
  not 
  infrequently 
  a 
  w^hole 
  field 
  may 
  be 
  

   destroyed. 
  The 
  life-history 
  of 
  the 
  insect 
  is 
  at 
  present 
  by 
  no 
  means 
  

   well 
  known. 
  In 
  Germany, 
  the 
  larvae 
  pupate 
  about 
  the 
  end 
  of 
  April 
  

   in 
  the 
  earth, 
  at 
  a 
  depth 
  of 
  about 
  four 
  inches, 
  and 
  the 
  first 
  generation 
  is 
  

   on 
  the 
  wing 
  from 
  the 
  middle 
  of 
  May 
  till 
  the 
  middle 
  of 
  July, 
  but 
  where 
  

   this 
  generation 
  lays 
  its 
  eggs 
  and 
  the 
  larvae 
  of 
  the 
  second 
  brood 
  live, 
  

   is 
  still 
  unknown, 
  although 
  it 
  is 
  believed 
  to 
  be 
  on 
  LoUmn 
  perenne 
  

   (Rye 
  Grass). 
  In 
  about 
  four 
  weeks 
  the 
  second 
  brood 
  is 
  on 
  the 
  wing 
  and 
  

   continues 
  into 
  the 
  autumn. 
  This 
  generation 
  lays 
  its 
  eggs 
  in 
  autumn, 
  

   not 
  directly 
  on 
  the 
  plants 
  of 
  winter 
  wheat, 
  but 
  in 
  the 
  earth, 
  and
