  Odynerus 
  eucharis. 
  

  

  Very 
  like 
  O. 
  homoeophanes 
  but 
  of 
  smaller 
  average 
  size, 
  the 
  wings 
  are 
  

   less 
  infuscate, 
  the 
  clypeus 
  of 
  the 
  male 
  is 
  only 
  spotted 
  with 
  red, 
  that 
  of 
  

   the 
  female 
  resembling 
  it 
  or 
  being 
  wholly 
  black, 
  there 
  is 
  no 
  red 
  line 
  in 
  the 
  

   emargination 
  of 
  the 
  eyes, 
  and 
  the 
  mesonotum 
  is 
  without 
  the 
  red 
  discal 
  

   and 
  marginal 
  lines. 
  The 
  puncturation 
  of 
  the 
  mesonotum 
  though 
  very 
  

   dense 
  is 
  distinct, 
  being 
  less 
  rugose, 
  that 
  of 
  the 
  second 
  abdominal 
  segment 
  

   fine 
  and 
  not 
  close, 
  except 
  on 
  the 
  apical 
  red 
  band; 
  its 
  impression 
  behind 
  

   the 
  costae 
  is 
  more 
  punctate, 
  but 
  more 
  shining.

  Odynerus 
  pseudochromoides 
  sp. 
  nov. 
  

  

  So 
  like 
  O. 
  pscudochromus 
  that 
  it 
  is 
  only 
  necessary 
  to 
  point 
  out 
  the 
  

   distinguishing 
  characters. 
  The 
  red 
  prothoracic 
  markings 
  are 
  continued 
  

   backwards 
  to 
  reach 
  the 
  tegulae, 
  the 
  costae 
  of 
  the 
  second 
  ventral 
  segment 
  

   are 
  moderately 
  distinct 
  and 
  the 
  surface 
  between 
  them 
  is 
  shining. 
  In 
  

   the 
  female 
  the 
  mesothorax 
  is 
  also 
  usually 
  more 
  shining.

  touching 
  the

  and 
  the

  somewhat 
  irregularly 
  punctured, 
  

   the 
  minute 
  punctures 
  between 
  the 
  large 
  ones 
  easily 
  seen 
  with 
  a 
  powerful 
  

   lens, 
  but 
  not 
  dense; 
  propodeum 
  smooth 
  and 
  shining 
  with 
  large 
  feeble 
  

   punctures 
  which 
  become 
  dense 
  and 
  more 
  distinct 
  in 
  the 
  concavity.
