  Ensina 
  sororcula,

  (1830). 
  

  

  Of 
  this 
  common 
  species 
  there 
  is 
  a 
  male 
  specimen 
  from 
  Natal, 
  Ulundi, 
  5,000-6,500

  (G.

  Ensina 
  gladiatrix, 
  sp. 
  nov. 
  

  

  Closely 
  allied 
  to 
  the 
  preceding 
  species, 
  but 
  distinguished 
  by 
  the 
  infuscated 
  

   antennae, 
  the 
  black 
  femora 
  which 
  have 
  only 
  a 
  very 
  narrow 
  yellowish 
  tip, 
  and 
  by 
  

   the 
  exceedingly 
  long 
  ovipositor 
  of 
  the 
  female.

  exserted 
  ovipositor 
  3

  ;

  Head 
  as 
  in 
  sororcula, 
  but 
  less 
  depressed 
  and 
  with 
  the 
  frons 
  distinctly 
  shorter 
  ; 
  

   ocellar 
  spot 
  blackish 
  ; 
  third 
  antennal 
  joint 
  distinctly 
  infuscated. 
  The 
  thorax 
  

   seems 
  to 
  be 
  darker 
  and 
  devoid 
  of 
  distinct 
  pattern 
  on 
  the 
  back 
  ; 
  the 
  pleurae 
  are 
  

   more 
  decidedly 
  blackish 
  ; 
  there 
  is 
  no 
  trace 
  of 
  a. 
  set. 
  The 
  abdomen 
  seems 
  likewise 
  

   to 
  be 
  darker 
  above 
  and 
  devoid 
  of 
  distinct 
  pattern 
  ; 
  the 
  ovipositor 
  is 
  shining 
  black, 
  

   depressed, 
  with 
  the 
  basal 
  segment 
  a 
  little 
  longer 
  than 
  the 
  whole 
  abdomen 
  (in 
  

   sororcula 
  it 
  is 
  about 
  a 
  half 
  as 
  long 
  as 
  the 
  abdomen), 
  the 
  second 
  segment 
  shining 
  

   black, 
  the 
  third 
  segment 
  reddish 
  ; 
  if 
  completely 
  exserted, 
  as 
  in 
  the 
  case 
  of 
  the 
  

   type, 
  the 
  ovipositor 
  is 
  longer 
  than 
  the 
  entire 
  body. 
  In 
  the 
  legs 
  all 
  the 
  femora 
  

   are 
  entirely 
  black, 
  having 
  only 
  the 
  extreme 
  tip 
  narrowly 
  yellowish, 
  while 
  in 
  sororcula 
  

   they 
  have 
  the 
  apical 
  half 
  yellowish, 
  and 
  the 
  four 
  anterior 
  ones 
  are 
  mainly 
  or 
  even 
  

   entirely 
  yellow. 
  The 
  wings 
  are 
  proportionally 
  broader 
  and 
  have 
  the 
  same 
  

   venation 
  ; 
  the 
  pattern 
  is 
  very 
  similar, 
  but 
  the 
  stigma 
  is 
  quite 
  black, 
  even 
  at 
  the 
  

   base 
  ; 
  the 
  fuscous 
  reticulation 
  is 
  more 
  developed 
  on 
  the 
  posterior 
  half 
  of 
  the 
  wing, 
  

   chiefly 
  in 
  the 
  discoidal 
  and 
  the 
  second 
  posterior 
  cells 
  ; 
  in 
  the 
  first 
  posterior 
  cell 
  the 
  

   hyaline 
  spots 
  are 
  disposed 
  in 
  two 
  distinct 
  longitudinal 
  rows, 
  a 
  condition 
  which 
  is 
  

   never 
  to 
  be 
  observed 
  in 
  sororcula, 
  in 
  which 
  they 
  are 
  not 
  very 
  distinct, 
  never 
  

   ordinate, 
  but 
  are 
  in 
  one 
  row 
  only 
  at 
  least 
  towards 
  the 
  middle 
  of 
  the 
  cell.
