  ; 
  Walker's 
  collection 
  con- 
  

   tained 
  only 
  a 
  single 
  specimen 
  ; 
  taken 
  by 
  Haliday 
  much 
  

   more 
  frequently 
  in 
  the 
  Hebrides 
  and 
  in 
  Ireland, 
  where 
  

   he 
  found 
  it 
  almost 
  gregarious 
  on 
  aquatic 
  plants 
  by 
  the 
  

   sides 
  of 
  rivers. 
  I 
  have 
  seen 
  no 
  specimens 
  except 
  my 
  

   own, 
  which 
  were 
  taken 
  formerly 
  by 
  sweeping 
  Nasturtium 
  

   officinale 
  in 
  a 
  ditch 
  near 
  Aylestone, 
  in 
  Leicestershire 
  ; 
  at 
  

   that 
  place 
  the 
  insects 
  were 
  not 
  uncommon, 
  but 
  no 
  

   varieties 
  occurred 
  among 
  them.

  Esenbeck 
  found 
  

   his 
  specimen 
  on 
  water-cress 
  near 
  Sickershausen, 
  and 
  

   received 
  others 
  from 
  Bohemia 
  and 
  Italy. 
  He 
  has 
  de- 
  

   scribed 
  a 
  second 
  species 
  as 
  Rogas 
  mutilator, 
  distinguished 
  

   chiefly 
  by 
  the 
  smoothness 
  of 
  the 
  3d 
  abdominal 
  segment 
  ; 
  

   of 
  this 
  I 
  captured 
  a 
  specimen 
  in 
  Corsica.
