  anterolaterally 
  (as 
  also 
  the

  not

  for

   almost

  Each 
  of 
  the 
  tergites 
  (except 
  the 
  

   apical) 
  has 
  a 
  slender 
  lateral 
  spine 
  which 
  is 
  an 
  elongate 
  tubercle 
  

   on 
  the 
  first 
  ones, 
  but 
  the 
  last 
  three 
  are 
  elongate, 
  laterally 
  

   porrect 
  except 
  the 
  apical 
  one 
  (on 
  the 
  penultimate 
  segment) 
  

   which 
  is 
  oblique. 
  According 
  to 
  Swezey, 
  the 
  whole 
  nymphal 
  

   period 
  occupies 
  29 
  to 
  34 
  days. 
  

  

  Fam. 
  Anthocoridae. 
  

  

  These 
  bugs 
  are 
  probably 
  mostly 
  insectivorous, 
  being 
  fierce 
  

   foes 
  of 
  Aphids, 
  Chermids, 
  Psocids, 
  Bark-beetles, 
  young 
  leaf- 
  

   hoppers, 
  etc., 
  though 
  they 
  perhaps 
  also 
  feed 
  on 
  minute 
  fungi. 
  

  

  The 
  only 
  notes 
  on 
  their 
  metamorphoses 
  are 
  those 
  of 
  Swezey 
  

   (^^), 
  who 
  has 
  partially 
  studied 
  them.

  The 
  eggs 
  are 
  elongate 
  oval 
  with 
  a 
  raised 
  collar 
  at 
  the 
  

   micropyle 
  end. 
  They 
  are 
  deposited 
  singly 
  on 
  leaves, 
  etc. 
  

  

  Fam. 
  Miridae. 
  

  

  The 
  known 
  ova 
  are 
  inserted, 
  much 
  as 
  in 
  Asiracids, 
  in 
  the 
  

   leaves 
  or 
  stems 
  of 
  plants. 
  The 
  metamorphoses 
  of 
  Poecilocapsus 
  

   Ivneatus 
  (^^) 
  and 
  Helopeltis 
  theivora 
  (^°), 
  etc., 
  have 
  been 
  

   studied. 
  

  

  This 
  family 
  is 
  mostly 
  phytophagous, 
  but 
  some 
  species 
  are 
  

   insectivorous, 
  caterpillars, 
  butterfly's 
  eggs, 
  aphidae, 
  etc., 
  form- 
  

   ing 
  their 
  prey. 
  Miris 
  dolahratus 
  has 
  been 
  reported 
  as 
  attacking 
  

   a 
  Dipterous 
  adult, 
  but 
  it 
  is 
  scarcely 
  credible, 
  the 
  bug 
  having 
  

   probably 
  been 
  really 
  a 
  Reduviolits. 
  Plagiognathus 
  ohscurus 
  

   is 
  recorded 
  as 
  biting 
  a 
  human 
  being.
