  This 
  fly, 
  belonging 
  to 
  the 
  family 
  Syrphidae, 
  in 
  the 
  larval 
  stage 
  

   causes 
  much 
  damage 
  to 
  narcissus 
  bulbs. 
  The 
  native 
  habitat 
  of 
  

   Merodon 
  equestris 
  is 
  Southern 
  Europe, 
  w^hence 
  it 
  has 
  spread 
  into 
  Eng- 
  

   land 
  and 
  Northern 
  Europe 
  and 
  later 
  to 
  America 
  and 
  New 
  Zealand. 
  

   The 
  larva 
  feeds 
  vigorously 
  on 
  the 
  soft 
  scale 
  of 
  the 
  bulb, 
  hollowing 
  out 
  

   the 
  centre, 
  so 
  that 
  infestation 
  is 
  often 
  difficult 
  to 
  detect. 
  The 
  larva, 
  

   pupa 
  and 
  adult 
  are 
  described. 
  The 
  eggs 
  are 
  laid 
  at 
  the 
  base 
  of 
  the 
  

   leaves 
  and 
  the 
  larvae 
  later 
  bore 
  into 
  the 
  bulb. 
  The 
  treatment 
  of 
  

   infested 
  bulbs 
  has 
  been 
  dealt

  During 
  the 
  season 
  of 
  1914 
  it 
  is 
  hoped 
  to 
  carry 
  on 
  the 
  distribution 
  of 
  

   this 
  beneficial 
  insect 
  on 
  a 
  greater 
  scale 
  than 
  in 
  the 
  past. 
  Mr. 
  Branigan 
  

   reports 
  a 
  number 
  of 
  colonies, 
  not 
  before 
  utilised, 
  in 
  the 
  Sierras, 
  and 
  it 
  

   is 
  hoped 
  to 
  exceed 
  the 
  hundred 
  million 
  before 
  the 
  end 
  of 
  the 
  year.

  Mr. 
  T. 
  Machida, 
  of 
  Japan, 
  recommends 
  for 
  the 
  woolly 
  aphis 
  the 
  

   following 
  mixture 
  : 
  — 
  Rape-seed 
  oil, 
  3 
  J 
  pints 
  ; 
  sulphur, 
  IJ 
  oz. 
  ; 
  tur- 
  

   pentine, 
  7J 
  oz. 
  The 
  rape-seed 
  oil 
  should 
  be 
  boiled 
  alone 
  for 
  a 
  short 
  

   time 
  and 
  then 
  the 
  turpentine 
  slowly 
  added 
  and 
  thoroughly 
  mixed. 
  

   Next 
  stir 
  in 
  the 
  crushed 
  sulphur. 
  The 
  attacked 
  parts 
  of 
  the 
  tree 
  are 
  

   painted 
  with 
  this 
  wash, 
  which 
  is 
  also 
  recommended 
  for 
  other 
  aphids 
  

   and 
  for 
  the 
  destruction 
  of 
  their 
  eggs.
