  Genus 
  CHOETOSPILA 
  Westwood 
  

  

  Choetospila 
  Westwood, 
  Thesaurus 
  entomologicus 
  Oxoniensis, 
  p, 
  137, 
  1874. 
  

   Choetospila 
  Dalla 
  Torre, 
  Catalogus 
  hymenopterorum, 
  vol. 
  5, 
  p. 
  207, 
  1898. 
  

   Spalmigiomor'pha 
  GiRAULT, 
  Mem. 
  Queensland 
  Mus., 
  vol, 
  2, 
  p. 
  333, 
  1913. 
  

  

  Choetospila 
  has 
  been 
  treated 
  as 
  a 
  synonym 
  of 
  Cerocephala 
  

   Westwood 
  by 
  Ashmead 
  (Mem. 
  Carnegie 
  Mus., 
  vol. 
  1, 
  p. 
  369, 
  1904) 
  

   and 
  others 
  but 
  may 
  be 
  easily 
  distinguished 
  from 
  that 
  genus 
  by 
  

   the 
  5-segmented 
  funicle 
  of 
  the 
  female. 
  

  

  Spalangiomorpha 
  was 
  synonymized 
  with 
  Choetospila 
  by 
  Girault 
  

   (Insecutor 
  Inscitiae 
  Menstruus, 
  vol. 
  5, 
  p. 
  37, 
  1917) 
  and 
  later 
  with 
  

   Cerocephala 
  by 
  the 
  same 
  author 
  in 
  one 
  of 
  his 
  privately 
  published 
  

   pamphlets 
  [Indications 
  (in 
  new 
  insects) 
  of 
  ruling 
  power 
  in 
  

   nature, 
  p. 
  3, 
  1925]. 
  In 
  a 
  still 
  later 
  publication 
  Girault 
  (Trans, 
  

   and 
  Proc. 
  Roy 
  Soc. 
  South 
  Australia, 
  vol. 
  53, 
  p. 
  319. 
  1929) 
  again 
  

   referred 
  to 
  the 
  genotype 
  species, 
  using 
  the 
  generic 
  name 
  Spalan- 
  

   giomorpha 
  but 
  pointing 
  out 
  that 
  the 
  species 
  agreed 
  with 
  Choeto- 
  

   spila 
  as 
  characterized 
  in 
  a 
  table 
  of 
  genera 
  by 
  Masi 
  (Nov. 
  Zool., 
  

   vol. 
  24, 
  p. 
  188, 
  1917). 
  I 
  agree 
  with 
  Waterston 
  (Rep. 
  Grain 
  Pest 
  

   Committee. 
  No. 
  9, 
  p. 
  25, 
  fig. 
  13, 
  1921) 
  that 
  Spalangiomorpha 
  is 
  

   certainly 
  a 
  synonym 
  of 
  Choetospila 
  Westwood. 
  

  

  Tiipe 
  of 
  the 
  genus.

  Choetospila
