  or 
  with 
  cuneiform 
  markings 
  on 
  anterior 
  margins 
  of 
  lat- 
  

   eral 
  lobes, 
  or 
  with 
  combination 
  of 
  two 
  or 
  more 
  of 
  these; 
  scutellum, 
  

   its 
  subtending 
  carinae, 
  and 
  posterior 
  margin 
  of 
  its 
  f

  ; 
  tegulae 
  ;

  an 
  oblique 
  

   band 
  on 
  mesopleuron 
  from 
  near 
  anterior 
  margin 
  to 
  middle 
  coxa; 
  a 
  

   larger 
  or 
  smaller 
  spot 
  on 
  each 
  side 
  of 
  mesosternum; 
  upper 
  division 
  

   of 
  metapleuron 
  and 
  its 
  lower 
  division 
  largely, 
  the 
  latter 
  with 
  the 
  

   ground 
  color 
  showing 
  only 
  below; 
  and 
  two 
  broad 
  marks 
  posteriorly 
  

   on 
  propodeum 
  embracing 
  the 
  apophyses, 
  very 
  rarely 
  confluent 
  ante- 
  

   riorly. 
  In 
  the 
  descriptions 
  this 
  color 
  pattern 
  is 
  referred 
  to 
  as 
  black 
  

   (or 
  red) 
  with 
  yellow 
  or 
  white 
  markings 
  and 
  the 
  exceptions 
  noted. 
  

  

  The 
  abdomen 
  is 
  either 
  largely 
  red 
  or 
  the 
  ground 
  color 
  is 
  black, 
  typi- 
  

   cally 
  with 
  broad 
  apical 
  and 
  lateral 
  margins 
  of 
  tergites 
  1-7, 
  lateral 
  

   margins 
  of 
  tergite 
  8, 
  and 
  the 
  petiole 
  more 
  or 
  less 
  yellow 
  or 
  whitish 
  ; 
  

   venter 
  white 
  with 
  sternites 
  darker. 
  In 
  the 
  following 
  descriptions 
  this 
  

   color 
  pattern 
  is 
  referred 
  to 
  merely 
  as 
  black, 
  the 
  tergites 
  margined 
  

   with 
  yellow 
  and 
  the 
  exceptions 
  noted. 
  

  

  SPECIFIC 
  CHARACTERS 
  

  

  For 
  the 
  most 
  part 
  Cryptanura 
  is 
  a 
  very 
  homogeneous 
  group 
  with 
  

   few 
  striking 
  structural 
  characters 
  that 
  will 
  serve 
  to 
  divide 
  it 
  into 
  spe- 
  

   cific 
  groups, 
  and 
  it 
  has 
  been 
  found 
  necessary 
  to 
  depend 
  to 
  a 
  consider- 
  

   able 
  extent 
  on 
  color 
  in 
  the 
  construction 
  of 
  the 
  following 
  key 
  to 
  species. 
  

  

  The 
  form 
  of 
  the 
  scutellum, 
  the 
  structure 
  of 
  the 
  propodeum 
  and 
  

   pronotum, 
  and 
  the 
  form 
  of 
  the 
  ovipositor 
  have 
  been 
  found 
  useful 
  as 
  

   group 
  characters, 
  though 
  the 
  last, 
  of 
  necessity 
  unisexual, 
  does 
  not 
  

   appear 
  to 
  be 
  accompanied 
  by 
  a 
  companion 
  character 
  in 
  the 
  opposite 
  

   sex. 
  

  

  A 
  considerable 
  number 
  of 
  the 
  described 
  species 
  have 
  not 
  been 
  avail- 
  

   able 
  for 
  study 
  and 
  have 
  been 
  omitted 
  from 
  the 
  following 
  key, 
  but 
  to 
  

   assist 
  in 
  the 
  identification 
  of 
  these 
  species 
  I 
  have 
  constructed 
  a 
  key 
  to 
  

   all 
  the 
  species, 
  based 
  largely 
  on 
  color. 
  This 
  will 
  be 
  found 
  following 
  

   the 
  descriptions 
  of 
  the 
  species 
  examined.
