  on 
  the 
  serious 
  ravages*

  A 
  memoir 
  by 
  M. 
  Leon 
  Dufour, 
  on 
  the 
  Diseases 
  of 
  Grapes,

  considerable 
  

   entomological

  The 
  advantage 
  of 
  protecting 
  insectivorous 
  birds, 
  with 
  a 
  view 
  to 
  the 
  destruction 
  of 
  

   insects 
  obnoxious 
  to 
  vegetables, 
  has 
  been 
  insisted 
  upon 
  by 
  M. 
  Buisson

  a 
  note

  A 
  suggestion 
  by 
  M. 
  Mocquerys, 
  of 
  Rouen, 
  as 
  to 
  the 
  services 
  rendered 
  to 
  agricultu- 
  

   turists 
  by 
  the 
  mole, 
  is 
  worthy 
  of 
  note. 
  On 
  repeated 
  dissection, 
  this 
  animal 
  has 
  been 
  

   found 
  to 
  be 
  insectivorous, 
  and 
  by 
  allowing 
  it 
  to 
  propagate, 
  great 
  numbers 
  of 
  the 
  larvas 
  

   of 
  Melolonthidae 
  would 
  be 
  consumed, 
  and 
  their 
  ravages 
  prevented,

  Monstrosities. 
  — 
  M. 
  Lucas 
  has 
  described 
  a 
  monstrosity 
  occurring 
  in 
  Colias 
  Edusa, 
  

   in 
  which 
  the 
  wings 
  and 
  other 
  organs 
  on 
  the 
  left 
  side 
  of 
  the 
  body, 
  as 
  well 
  as 
  the 
  mark- 
  

   ings 
  of 
  its 
  wings, 
  were 
  considerably 
  diminished 
  in 
  size, 
  (Ann. 
  Soc. 
  Ent. 
  France, 
  1851, 
  

  

  * 
  Some 
  idea 
  may 
  be 
  formed 
  of 
  the 
  extent 
  of 
  these 
  ravages, 
  when 
  it 
  is 
  mentioned 
  

   that 
  a 
  crop 
  which, 
  in 
  the 
  preceding 
  year, 
  realized 
  7,500 
  francs 
  was 
  reduced 
  in 
  value 
  

   to 
  3,700.
