  Because 
  of 
  BruUe's 
  juistukcn 
  idcu 
  tluit 
  the 
  specimens 
  on 
  which 
  he 
  

   based 
  the 
  genus 
  C 
  ryptanxLva 
  were 
  fenuiles 
  "with 
  concealed 
  ovipositors, 
  

   this 
  genus 
  of 
  ichneumon-flies 
  was 
  misunderstood 
  until 
  Roman 
  (1910) 
  

   identified 
  it 
  as 
  the 
  male 
  of 
  Polydeinis 
  Cresson 
  and 
  synonymized 
  the 
  

   latter 
  genus 
  with 
  Crijptanura. 
  

  

  I'he 
  genus 
  dates 
  from 
  1845, 
  when 
  the 
  figure 
  of 
  Cryptanura 
  nigripes 
  

   Brulle 
  was 
  published 
  in 
  the 
  atlas 
  of 
  Lepeletiers 
  'Tlistoire 
  Natnrelle 
  

   des 
  Insectes," 
  although 
  tlie 
  description 
  did 
  not 
  appear 
  until 
  the 
  fol- 
  

   hjwing 
  year. 
  It 
  is 
  therefore 
  a 
  monobasic 
  genus 
  with 
  nigripes 
  Brulle 
  

   as 
  g<'notype. 
  On 
  this 
  basis, 
  and 
  assuming 
  that 
  nigr/pcfi 
  and 
  .sfriafa 
  

   Brulle 
  are 
  not 
  congeneric, 
  Viereck 
  took 
  exception 
  to 
  Roman's 
  synon}'- 
  

   mizing 
  of 
  Polyaenttfi 
  Cresson 
  with 
  Cryptanura. 
  Viereck's 
  statement 
  

   that 
  these 
  two 
  species 
  are 
  not 
  congeneric 
  must 
  have 
  been 
  based 
  on 
  the 
  

   fact 
  that 
  Brulle 
  does 
  not 
  state 
  definitely 
  that 
  nigripes 
  has 
  the 
  two 
  

   small 
  frontal 
  horns 
  characteristic 
  of 
  striata; 
  but 
  by 
  inference 
  he 
  

   certainly 
  does 
  ascribe 
  this 
  character 
  to 
  nigripes^ 
  for 
  in 
  the 
  description 
  

   of 
  all 
  the 
  species 
  that 
  follow 
  sfn'tifa 
  he 
  mentions 
  only 
  the 
  cliuiinters 
  

   by 
  which 
  they 
  differ 
  from 
  it 
  and 
  from 
  one 
  another. 
  

  

  Cresson 
  and 
  Cameron 
  were 
  in 
  error 
  in 
  their 
  inter])retati()ns 
  of 
  the 
  

   genus, 
  the 
  species 
  assigned 
  to 
  it 
  by 
  those 
  authoi's 
  Ijeing

  the 
  genus 
  correctly.
