  Three 
  females, 
  the 
  type 
  taken 
  by 
  C. 
  V. 
  Piper 
  in 
  July, 
  1902; 
  one 
  

   taken 
  at 
  Olympia, 
  Wash., 
  June 
  2, 
  1897; 
  and 
  one 
  from 
  Santa 
  Cruz 
  

   Mountains, 
  Calif.; 
  and 
  one 
  male 
  (the 
  allotype) 
  taken 
  June 
  24, 
  1920, 
  

   by 
  M. 
  C. 
  Lane. 
  

  

  Both 
  paratype 
  females 
  have 
  small 
  white 
  markings 
  on 
  the 
  humeral 
  

   angles 
  of 
  the 
  pronotum, 
  and 
  the 
  California 
  specimen 
  has 
  small 
  

   spots 
  also 
  on 
  the 
  frontal 
  orbits. 
  The 
  latter 
  also 
  has 
  the 
  postpetiole 
  

   as 
  in 
  the 
  male. 
  

  

  Genus 
  APAELETICUS 
  Wesmael 
  

  

  This 
  genus 
  has 
  not 
  heretofore 
  been 
  recognized 
  in 
  the 
  North 
  Ameri- 
  

   can 
  fauna, 
  though 
  Bradley 
  * 
  has 
  somewhat 
  doubtfully 
  referred 
  to 
  it 
  

   Platylabus 
  ihoracicus 
  Cresson, 
  eryihropygus 
  Provancher, 
  and 
  quadri- 
  

   carinatus 
  Provancher 
  which 
  he 
  excluded 
  from 
  Platylabus 
  because 
  of 
  

   their 
  circular 
  propodeal 
  spiracles. 
  This 
  character 
  is 
  too 
  variable 
  in 
  

   the 
  genus 
  to 
  exclude 
  the 
  three 
  species 
  from 
  Platylabus, 
  to 
  which 
  they 
  

   are 
  hereby 
  restored. 
  Moreover, 
  they 
  lack 
  the 
  very 
  peculiar 
  female 
  

   abdominal 
  conformation 
  so 
  characteristic 
  of 
  Apaeleticus. 
  

  

  The 
  following 
  new 
  species 
  appears 
  to 
  be 
  a 
  true 
  Apaeleticus.
