  these 
  were 
  found 
  to 
  be 
  parasitised 
  except 
  Hyperasjois 
  sp. 
  The 
  larvae 
  

   were 
  attacked 
  at 
  any 
  point, 
  while 
  the 
  adults 
  seemed 
  to 
  be 
  attacked 
  

   only 
  between 
  the 
  segments. 
  The 
  parasite, 
  before 
  ovipositing, 
  perceives 
  

   the 
  presence 
  of 
  the 
  beetles 
  from 
  a 
  distance 
  of 
  at 
  least 
  an 
  inch, 
  when 
  

   she 
  shows 
  great 
  excitement 
  by 
  rapid 
  vibration 
  of 
  the 
  antennae 
  and 
  

   quick 
  movement 
  towards 
  the 
  beetle, 
  then 
  rushing 
  in 
  and 
  giving 
  a 
  

   quick 
  thrust 
  with 
  her 
  ovipositor. 
  It 
  is 
  probable 
  that 
  the 
  parasite 
  

   hibernates 
  as 
  a 
  larva 
  within 
  the 
  host. 
  

  

  Paniscus 
  geminatus, 
  Say, 
  was 
  found 
  as 
  an 
  external 
  parasite 
  on 
  an 
  

   undetermined 
  Lepidopterous 
  larva 
  found 
  under 
  a 
  band 
  on 
  an 
  apple 
  

   tree. 
  

  

  The 
  Chalcid, 
  Sphaeropyx 
  bicolor, 
  Cress., 
  was 
  frequently 
  taken 
  in 
  

   immature 
  stages 
  as 
  a 
  parasite 
  of 
  Acronyda 
  clarescens, 
  Guen. 
  This 
  

   parasite 
  is 
  gregarious, 
  as 
  many 
  as 
  30 
  having 
  been 
  reared 
  from 
  a 
  single 
  

   host. 
  The 
  total 
  period 
  from 
  the 
  emergence 
  of 
  the 
  larva 
  from 
  the 
  host 
  

   to 
  the 
  issue 
  of 
  the 
  adult 
  is 
  20-21 
  days. 
  From 
  some 
  hosts 
  only 
  males 
  

   were 
  reared, 
  and 
  from 
  others 
  only 
  females, 
  but 
  from 
  the 
  majority 
  

   parasites 
  of 
  both 
  sexes 
  emerged, 
  the 
  males 
  issuing 
  one 
  or 
  two 
  days 
  

   ahead 
  of 
  the 
  females. 
  From 
  22 
  hosts 
  there 
  were 
  reared 
  296 
  females 
  

   and 
  86 
  males. 
  The 
  parasite 
  hibernates 
  as 
  a 
  larva 
  within 
  its 
  cocoon 
  ; 
  

   frequently 
  it 
  is 
  attacked 
  in 
  the 
  cocoon 
  by 
  an 
  omnivorous 
  hyper- 
  

   parasite, 
  Dibrachys 
  boucheanus, 
  Ratz., 
  but 
  it 
  is 
  seldom 
  that 
  all 
  the 
  

   cocoons 
  in 
  a 
  mass 
  are 
  parasitised. 
  Some 
  eggs 
  of 
  two 
  species 
  of 
  

   Acronyda, 
  one 
  of 
  which 
  feeds 
  on 
  wild 
  cherry, 
  and 
  the 
  other 
  on 
  pear, 
  

   were 
  exposed 
  to 
  S. 
  bicolor 
  ; 
  while 
  the 
  parasites 
  took 
  no 
  notice 
  of 
  the 
  

   eggs, 
  they 
  showed 
  great 
  excitement 
  when 
  on 
  leaves 
  bearing 
  eggs, 
  

   running 
  rapidly 
  about, 
  dragging 
  their 
  ovipositors 
  over 
  the 
  surface 
  

   of 
  the 
  leaf 
  and 
  searching 
  minutely 
  with 
  their 
  antennae. 
  No 
  such 
  

   excitement 
  was 
  shown 
  when 
  uninfested 
  leaves 
  were 
  supplied, 
  a 
  fact 
  

   suggesting 
  that 
  the 
  search 
  for 
  hosts 
  may 
  possibly 
  be 
  guided 
  somewhat 
  

   by 
  the 
  scent 
  left 
  by 
  the 
  parent 
  moth 
  on 
  the 
  leaves 
  on 
  which 
  she 
  

   oviposits. 
  A 
  few 
  days 
  later 
  the 
  Acronycta 
  eggs 
  hatched, 
  and 
  the 
  

   larvae 
  were 
  exposed 
  to 
  the 
  parasites, 
  and 
  were 
  immediately 
  attacked. 
  

   Older 
  larvae 
  were 
  never 
  touched.

  In 
  the 
  course 
  of 
  work 
  on 
  forest 
  Lepidoptera 
  the 
  author 
  has 
  bred 
  

   several 
  specimens 
  of 
  Marmara 
  fidgidella, 
  Clemens, 
  from 
  oak. 
  The 
  

   larva 
  of 
  this 
  insect 
  forms 
  long 
  winding 
  galleries 
  just 
  under 
  the 
  epidermis 
  

   of 
  young 
  trunks 
  and 
  branches 
  of 
  oak, 
  and 
  leaves 
  the 
  mine 
  early 
  in 
  

   the 
  spring 
  to 
  spin 
  a 
  small 
  cocoon 
  in 
  some 
  crack 
  in 
  the 
  bark. 
  Similar 
  

   Marmara 
  mines 
  were 
  found 
  less 
  commonly 
  on 
  chestnut 
  ; 
  the 
  imago 
  

   was 
  not 
  secured, 
  but 
  it 
  is 
  thought 
  that 
  it 
  may 
  prove 
  to 
  be 
  the 
  same 
  

   species 
  or 
  one 
  of 
  the 
  allied 
  forms, 
  fascilla, 
  Chmb., 
  or 
  elotella, 
  Busck, 
  

   at 
  present 
  listed 
  under 
  the 
  genus 
  Gracilaria.
