  and 
  the 
  middle 
  joints 
  may 
  show 
  a 
  tendency 
  towards 
  fuscous 
  

   coloration. 
  In 
  size 
  there 
  is 
  some 
  variation. 
  

  

  Ammopiiila 
  nigripes, 
  Smith. 
  

  

  A 
  specimen 
  from 
  Barrackpore 
  agrees 
  with 
  Smith's 
  

   description 
  so 
  far 
  as 
  it 
  goes. 
  It 
  is 
  fully 
  one 
  line 
  longer 
  ; 
  

   the 
  hair 
  on 
  the 
  thorax 
  is 
  longish 
  and 
  tolerably 
  thick 
  ; 
  the 
  

   clypeus 
  is 
  broadly 
  transverse 
  at 
  the 
  apex, 
  the 
  sides 
  being 
  

   angled 
  ; 
  the 
  mesonotum 
  is 
  furrowed 
  in 
  the 
  centre 
  ; 
  the 
  legs 
  

   are 
  thickly 
  pruinose 
  ; 
  the 
  second 
  cubital 
  cellule 
  at 
  the 
  top 
  

   is 
  about 
  one-fourth 
  shorter 
  than 
  the 
  third, 
  and 
  about 
  equal 
  

   in 
  length 
  to 
  the 
  space 
  bounded 
  by 
  the 
  second 
  recurrent 
  and 
  

   second 
  transverse 
  cubital 
  nervures 
  ; 
  the 
  third 
  cubital 
  cellule 
  

   is 
  almost 
  equal 
  in 
  length 
  at 
  top 
  and 
  bottom, 
  and 
  the 
  third 
  

   transverse 
  cubital 
  nervure 
  is 
  sharply 
  elbowed 
  a 
  little 
  below 
  

   the 
  middle. 
  

  

  Ammophila 
  atripes, 
  Smith. 
  

  

  The 
  Barrackpore 
  specimens 
  of 
  this 
  species, 
  as 
  named 
  by 
  

   Smith, 
  are 
  uniform 
  in 
  coloration 
  — 
  black, 
  the 
  second 
  joint 
  of 
  

   petiole 
  is 
  red 
  beneath, 
  the 
  first 
  joint 
  black, 
  the 
  other 
  seg- 
  

   ments 
  steel-blue 
  ; 
  the 
  wings 
  more 
  or 
  less 
  fuscous, 
  the 
  

   nervures 
  black. 
  Face 
  and 
  clypeus 
  densely 
  covered 
  with 
  

   silvery 
  white 
  pile 
  ; 
  apex 
  of 
  clypeus 
  transverse, 
  the 
  sides 
  

   rounded 
  ; 
  vertex 
  and 
  front 
  with 
  scattered 
  punctures, 
  shining. 
  

   Pro- 
  and 
  mesonotum 
  strongly 
  transversely 
  striolated 
  ; 
  meta- 
  

   notum 
  more 
  closely 
  and 
  not 
  so 
  strongly 
  ; 
  scutellum 
  and 
  post 
  

   scutellum 
  longitudinally 
  striolated 
  ; 
  pleurae 
  rugose. 
  The 
  

   pubescence 
  on 
  the 
  thorax 
  is 
  short 
  and 
  cinereous 
  ; 
  the 
  

   abdomen 
  is 
  thickly 
  pruinose. 
  At 
  the 
  top 
  the 
  second 
  cubital 
  

   cellule 
  is 
  about 
  one-half 
  the 
  length 
  of 
  the 
  third, 
  and 
  a 
  little 
  

   more 
  than 
  the 
  space 
  bounded 
  by 
  the 
  second 
  recurrent 
  and 
  

   second 
  transverse 
  cubital 
  nervures 
  ; 
  the 
  third 
  cubital 
  cellule 
  

   is 
  nearly 
  equal 
  in 
  length 
  at 
  top 
  and 
  bottom 
  ; 
  the 
  third 
  

   transverse 
  cubital 
  nervure 
  is 
  elbowed 
  near 
  the 
  middle.
