  bred 
  bj 
  Mr. 
  Swezey 
  and 
  myself 
  from 
  the 
  puparium 
  of 
  the 
  

   ISTeuropterous 
  Anomaloclirysa, 
  and 
  one 
  by 
  Mr. 
  Terry 
  from 
  the 
  

   eggs 
  of 
  the 
  Locustid, 
  Brachy^netopa. 
  Another 
  I 
  have 
  bred 
  

   freely 
  from 
  very 
  rotten 
  wet 
  wood, 
  which 
  yielded 
  otherwise 
  only 
  

   Lepidopterous 
  (Gelechiid) 
  larvae, 
  but 
  in 
  this 
  case 
  the 
  host 
  is 
  

   necessarily 
  uncertain. 
  

  

  The 
  species 
  are 
  very 
  difficult 
  to 
  determine, 
  being 
  variable, 
  

   and 
  with 
  extreme 
  sexual 
  dimorphism, 
  so 
  that 
  the 
  sexes 
  can 
  not 
  

   possibly 
  be 
  correlated 
  except 
  by 
  breeding. 
  Judging 
  by 
  the 
  

   bred 
  specimens 
  I 
  have 
  examined, 
  there 
  is 
  no 
  such 
  variation 
  in 
  

   the 
  length 
  of 
  the 
  ovipositor, 
  as 
  Ashmead 
  allows 
  in 
  his 
  descrip- 
  

   tions 
  in 
  the 
  Fauna 
  Hawaiiensis, 
  and 
  the 
  sexes 
  are 
  almost 
  cer- 
  

   tainly 
  wrongly 
  assigned 
  in 
  that 
  work. 
  I 
  have 
  somewhat 
  reluc- 
  

   tantly 
  described 
  this 
  egg-parasite 
  of 
  Khyncogonus, 
  for 
  though 
  

   I 
  am 
  quite 
  satisfied 
  it 
  is 
  undescribed, 
  I 
  do 
  not 
  feel 
  that 
  the 
  

   material 
  of 
  this 
  genus 
  that 
  is 
  accessible 
  to 
  me 
  for 
  study 
  at 
  the 
  

   present 
  time, 
  is 
  sufficient 
  for 
  a 
  proper 
  understanding 
  of 
  the 
  

   importance 
  of 
  specific 
  characters 
  in 
  the 
  Hawaiian 
  species. 
  

   Nothing 
  is 
  likely 
  to 
  prove 
  a 
  greater 
  hindrance 
  to 
  the 
  advance 
  

   of 
  knowledge 
  of 
  the 
  Hawaiian 
  fauna 
  than 
  the 
  description 
  of 
  

   new 
  forms 
  off-hand 
  in 
  these 
  difficult 
  genera 
  of 
  many 
  endemic 
  

   species, 
  when 
  one 
  is 
  imperfectly 
  acquainted 
  with 
  the 
  value 
  of 
  

   their 
  characters, 
  and 
  these 
  can 
  only 
  be 
  appreciated 
  after 
  study- 
  

   ing 
  a 
  comprehensive 
  collection. 
  The 
  material 
  accessible 
  to 
  me 
  

   for 
  study 
  and 
  comparison 
  is 
  less 
  than 
  two 
  hundred 
  specimens 
  

   of 
  indigenous 
  Eupelmus 
  and 
  I 
  should 
  be 
  very 
  pleased 
  to 
  obtain 
  

   specimens 
  (which 
  are 
  the 
  most 
  easily 
  collected 
  of 
  all 
  native 
  

   Chalcids) 
  from 
  the 
  members 
  of 
  the 
  Society. 
  With 
  a 
  thousand 
  

   examples 
  from 
  varioiis 
  localities, 
  an 
  adequate 
  knowledge 
  of 
  

   the 
  Hawaiian 
  forms 
  might 
  be 
  obtained 
  and 
  the 
  Hawaiian 
  

   species 
  redeseribed 
  to 
  advantage. 
  The 
  fact 
  that 
  this 
  species 
  

   has 
  been 
  bred, 
  and 
  the 
  interest 
  that 
  attaches 
  to 
  it 
  in 
  connection 
  

   with 
  Mr. 
  Giifard's 
  paper 
  on 
  the 
  habits 
  of 
  Rhyncogonus 
  hlach- 
  

   hurni, 
  may 
  excuse 
  the 
  deficiencies, 
  which 
  will 
  no 
  doubt 
  be 
  sub- 
  

   sequently 
  found, 
  in 
  my 
  description. 
  

  

  Eupelmus

  nov. 
  

  

  Female, 
  metallic 
  green, 
  the 
  face 
  blue-black 
  or 
  purplish 
  

   black, 
  the 
  thorax 
  and 
  head 
  with 
  more 
  or 
  less 
  brassy 
  reflections 
  

   in 
  parts, 
  the 
  abdomen 
  usually 
  metallic 
  blue, 
  green 
  in 
  part; 
  

   the

  of 
  the 
  antennae, 
  all 
  the 
  legs 
  including 
  the 
  coxae, 
  and 
  

   the 
  mesopleura 
  are 
  testaceous

  the

  darker, 
  more 
  brown
