  Five 
  females 
  and 
  one 
  male 
  all 
  reared 
  by 
  Alan 
  P. 
  Dodd, 
  of 
  the 
  

   Prickly 
  Pear 
  Board 
  of 
  Australia 
  from 
  lepidopterous 
  larvae 
  boring 
  in 
  

   Opuntia. 
  

  

  All 
  but 
  one 
  of 
  the 
  specimens 
  were 
  reared 
  as 
  parasites 
  of 
  Cactobrosis 
  

   strigalis 
  Barnes 
  and 
  McDunnough, 
  Paratype 
  b 
  having 
  parasitized 
  

   Zophodia 
  glaucatetta 
  Hulst. 
  Paratype 
  a 
  is 
  from 
  the 
  allotype-locality, 
  

   Paratype 
  b 
  from 
  Uvalde, 
  Texas, 
  and 
  the 
  other 
  two, 
  which 
  are 
  returned 
  

   to 
  Mr. 
  Dodd, 
  are 
  from 
  the 
  type-locality. 
  

  

  Paratype 
  a 
  and 
  the 
  two 
  returned 
  to 
  Mr. 
  Dodd 
  are 
  essentially 
  like 
  

   the 
  type 
  while 
  Paratype 
  b 
  is 
  even 
  less 
  extensively 
  and 
  less 
  distinctly 
  

   marked 
  than 
  the 
  allotype.
