  A 
  series 
  of 
  eight 
  females 
  was 
  bred 
  by 
  Mr. 
  Neave 
  from 
  the 
  pupa 
  of 
  a 
  butterfly 
  

   (Charaxes 
  sp.). 
  The 
  insect 
  is 
  not 
  improbably 
  a 
  hyperparasite 
  on 
  some 
  species 
  of 
  

   Chalcis.

  The 
  mandibles 
  are 
  essentially 
  as 
  in 
  the 
  type, 
  and 
  the 
  differences 
  in 
  sculpture 
  

   (slightly 
  coarser) 
  are 
  such 
  as 
  might 
  be 
  expected 
  with 
  the 
  greater 
  size.

   These
