  Cameron, 
  Hymenoptera 
  Orientalia. 
  

  

  given 
  by 
  Brulle 
  {Hymen. 
  IV., 
  p. 
  266), 
  and 
  with 
  his 
  figure 
  

   (//. 
  4.1,/. 
  i) 
  of 
  Hemigaster, 
  of 
  which 
  he 
  describes 
  a 
  species 
  

   from 
  India 
  and 
  another 
  from 
  Australia, 
  if 
  he 
  has 
  not 
  

   made 
  a 
  mistake 
  about 
  the 
  latter, 
  for 
  he 
  describes 
  it 
  as 
  a 
  

   Hemite/es, 
  which 
  is 
  probably 
  a 
  slip 
  of 
  the 
  pen. 
  In 
  some 
  

   respects 
  the 
  genus 
  is 
  intermediate, 
  judging 
  by 
  the 
  species 
  

   here 
  described, 
  between 
  the 
  fc/inewnontdes 
  and 
  the 
  Cryptides. 
  

  

  The 
  generic 
  characters 
  of 
  our 
  species 
  ma)' 
  be 
  repre- 
  

   sented 
  as 
  follows. 
  Antennae 
  longish, 
  thickened 
  towards 
  the 
  

   apex. 
  Eyes 
  large, 
  margined, 
  front 
  widely 
  and 
  deeply 
  de- 
  

   pressed, 
  tricarinate 
  in 
  the 
  middle, 
  the 
  inner 
  orbits 
  on 
  the 
  

   lower 
  side 
  stoutly 
  keeled 
  ; 
  face 
  distinctly 
  keeled 
  down 
  the 
  

   middle, 
  mandibles 
  bidentate 
  at 
  the 
  apex. 
  Parapsidal 
  

   furrows 
  distinct, 
  scutellum 
  stoutly 
  keeled. 
  Median 
  seg- 
  

   ment 
  completely 
  areolated. 
  Spiracles 
  large, 
  linear. 
  

   Areolet 
  absent 
  ; 
  radial 
  cellule 
  large, 
  wide, 
  the 
  apical 
  half 
  

   broadly 
  lanceolate. 
  The 
  basal 
  three 
  segments 
  of 
  the 
  

   abdomen 
  large, 
  the 
  others 
  small 
  ; 
  the 
  petiole 
  bent 
  at 
  the 
  

   apex 
  ; 
  the 
  spiracles 
  small, 
  round, 
  placed 
  at 
  the 
  base 
  of 
  the 
  

   apical 
  third 
  ; 
  the 
  gastrocceli 
  obsolete. 
  Tarsi 
  spinose, 
  the 
  

   claws 
  simple. 
  

  

  The 
  following 
  new 
  genera 
  and 
  species 
  are 
  described 
  

   here 
  somewhat 
  out 
  of 
  their 
  natural 
  order 
  pending 
  the 
  

   completion 
  of 
  the 
  examination 
  of 
  the 
  groups 
  to 
  which 
  

   they 
  belong. 
  

  

  Ileanta, 
  gen. 
  nov. 
  

  

  Belongs 
  to 
  Wesmael 
  tribe 
  of 
  the 
  Ichneumones, 
  and 
  is 
  

   most 
  nearly 
  related 
  to 
  Ichneumon, 
  from 
  which 
  it 
  differs, 
  as 
  

   it 
  does 
  from 
  all 
  other 
  Ichncumonidce, 
  in 
  the 
  basal 
  joint 
  of 
  

   the 
  hinder 
  tarsi 
  having, 
  on 
  the 
  lower 
  side, 
  a 
  flattened 
  leaf- 
  

   like 
  expansion 
  extending 
  from 
  the 
  base 
  to 
  near 
  the 
  apex,
