  Ammophila 
  erytiirocephala, 
  Fab. 
  

  

  This 
  large 
  and 
  striking 
  species 
  is 
  a 
  Parapsamniophila. 
  

   The 
  head 
  is 
  large 
  ; 
  the 
  eyes 
  reach 
  onh- 
  exactly 
  opposite 
  

   the 
  level 
  of 
  the 
  hind 
  ocelli, 
  the 
  vertex 
  being 
  much 
  more 
  

   developed 
  behind 
  them 
  than 
  usual 
  ; 
  they 
  are 
  quite 
  parallel, 
  

   not 
  converging 
  at 
  the 
  bottom 
  as 
  in 
  A. 
  violaceipennis 
  ; 
  the 
  

   antennae 
  issue 
  from 
  nearl}- 
  opposite 
  their 
  middle, 
  and 
  not 
  

   so 
  high 
  up 
  as 
  in 
  the 
  latter 
  species 
  ; 
  the 
  clypeus 
  does 
  not 
  

   project 
  in 
  the 
  middle, 
  and 
  is 
  truncated 
  at 
  the 
  apex. 
  The 
  

   mandibles 
  are 
  very 
  large 
  and 
  projecting, 
  almost 
  as 
  in 
  

   Ampulex. 
  The 
  neuration 
  of 
  the 
  wings 
  is 
  very 
  much 
  as 
  in 
  

   ViolaceipeJinis. 
  Antennae 
  black, 
  pilose 
  ; 
  the 
  3 
  — 
  4 
  basal 
  

   joints 
  red, 
  the 
  third 
  is 
  nearly 
  twice 
  the 
  length 
  of 
  the 
  fourth.

  Head 
  shining, 
  sparsely 
  punctured 
  ; 
  the 
  clypeus 
  and 
  face 
  

   covered 
  with 
  silvery 
  pubescence 
  ; 
  the 
  front 
  and 
  vertex 
  with 
  

   longish, 
  blackish 
  hair 
  ; 
  clypeus 
  somewhat 
  projecting 
  ; 
  the 
  

   apex 
  with 
  a 
  distinct 
  margin, 
  a 
  little 
  sinuated 
  ; 
  mandibles 
  

   broadly 
  red 
  in 
  the 
  middle. 
  The 
  antennae 
  incline 
  to 
  fuscous 
  

   beneath, 
  especially 
  at 
  the 
  base 
  ; 
  the 
  third 
  joint 
  is 
  longer 
  

   than 
  the 
  first 
  and 
  second 
  joints 
  united, 
  and 
  about 
  one-fourth 
  

   longer 
  than 
  the 
  fourth. 
  Thorax 
  densely 
  covered 
  with 
  

   blackish 
  hair 
  ; 
  coarsely 
  punctured

  mesonotum 
  rugo.sely 
  

   striolated

  striolated 
  ;

  cubital 
  cellules 
  above 
  subequal 
  ; 
  

   the 
  transverse 
  cubital 
  cellules 
  elbowed 
  towards 
  the 
  middle, 
  

   thus 
  making 
  the 
  third 
  cubital 
  cellule 
  wider 
  in 
  the 
  middle 
  

   than 
  at 
  top 
  or 
  bottom 
  ;

  first 
  recurrent 
  nervure 
  is 
  recei\-ed
