  and 
  is 
  an 
  immigrant 
  into 
  Hawaii. 
  It 
  is 
  distributed 
  over 
  the 
  

   entire 
  Oriental 
  Region, 
  running 
  into 
  the 
  Palearctic 
  in 
  Japan 
  

   and 
  China 
  ; 
  it 
  is 
  also 
  recorded 
  from 
  Celebes 
  and 
  New 
  Caledonia. 
  

  

  Lygaeidae. 
  

  

  The 
  ova 
  in 
  all 
  cases 
  known 
  to 
  me 
  are 
  of 
  very 
  similar 
  form, 
  

   i. 
  e. 
  "Kidney-bean 
  shaped." 
  Myrmus 
  miriformis 
  (^^). 
  Dalader 
  

   acidicosta 
  {^^), 
  Anasa 
  tristis 
  (^^), 
  Leptocoris 
  trivlttatus 
  (^^), 
  

   etc., 
  have 
  been 
  figured 
  and 
  with, 
  generally, 
  some 
  nymphal 
  

   instars. 
  

  

  The 
  lifehistory 
  of 
  Myodocha 
  acuta 
  is 
  also 
  now 
  fairly 
  well 
  

   kno\vii 
  ("*). 
  

  

  Like 
  the 
  Cimicidae, 
  some 
  Lygaeids 
  are 
  carnivorous, 
  some 
  

   phytophagous. 
  They 
  are 
  subjected 
  to 
  the 
  attacks 
  of 
  very 
  simi- 
  

   lar 
  parasites; 
  Anasa 
  is 
  attacked 
  by 
  Ti-ichopoda 
  (a 
  Tachinid), 
  

   by 
  Telenomus 
  and 
  Hadi^onotus 
  (Hymenopterous 
  egg-parasites) 
  

   and 
  by 
  a 
  bacterial 
  disease. 
  PhyUomorpha 
  laciniata 
  is 
  re- 
  

   markable 
  for 
  its 
  stridulation 
  and 
  its 
  mode 
  of 
  carrying 
  its 
  

   ova 
  {'"). 
  

  

  4 
  Rhopalus 
  hyalinus 
  Liiineus. 
  

  

  This 
  species 
  is 
  almost 
  cosmopolitan 
  and 
  is 
  firmly 
  established 
  

   in 
  the 
  Hawaiian 
  Isles, 
  though 
  it 
  must 
  be 
  a 
  comparatively 
  

   recent 
  introduction, 
  as 
  Blackburn 
  did 
  not 
  take 
  it. 
  Its 
  principal 
  

   food-plant 
  is 
  Pualele 
  (Sonchus 
  oleraceus) 
  upon 
  the 
  young, 
  

   closed, 
  flowerbuds 
  (and 
  sometimes 
  stems) 
  on 
  which 
  the 
  bright 
  

   red 
  eggs 
  are 
  laid 
  in 
  clusters. 
  I 
  have 
  also 
  found 
  them 
  on 
  

   I\im{i(Sida 
  cordifolia) 
  at 
  sea 
  level 
  and 
  Mr. 
  Swezey 
  records 
  

   them 
  from 
  Eiiphorbia 
  cordata 
  and 
  other 
  plants. 
  They 
  have 
  

   been 
  reported 
  from 
  SaccTmrum 
  officinarum, 
  but 
  they 
  were 
  cer- 
  

   tainly 
  from 
  clumps 
  of 
  Sonchus 
  in 
  the 
  canefields. 
  

  

  In 
  this 
  species, 
  as 
  in 
  Nysiu^ 
  vinitor 
  and 
  delectus, 
  the 
  male 
  

   and 
  female 
  copulate 
  end 
  to 
  end, 
  both 
  dorsal 
  and 
  horizontal. 
  

   They 
  can 
  recopulate 
  several 
  times 
  with 
  tlie 
  same 
  partner.
