  This 
  species 
  is 
  a 
  pest 
  of 
  green 
  gram, 
  and 
  Mr. 
  T. 
  Bainbrigge 
  Fletcher 
  gives 
  the 
  

   following 
  information 
  concerning 
  it 
  : 
  " 
  The 
  eggs 
  are 
  laid 
  in 
  a 
  hole 
  bored 
  in 
  a 
  seed 
  

   of 
  green 
  gram 
  (Phaseolus 
  mungo) 
  or 
  cow-pea, 
  the 
  female 
  having 
  previously 
  eaten 
  

   her 
  way 
  inside 
  the 
  pod. 
  Three 
  eggs 
  are 
  usually 
  laid 
  in 
  one 
  pod, 
  one 
  at 
  each 
  end 
  

   and 
  the 
  third 
  in 
  the 
  middle 
  of 
  the 
  pod. 
  The 
  grub 
  on 
  hatching 
  feeds 
  on 
  the 
  seed, 
  

   devouring 
  three 
  or 
  four 
  seeds 
  before 
  it 
  is 
  full-fed, 
  when 
  it 
  emerges 
  from 
  the 
  pod 
  

   and 
  drops 
  to 
  the 
  ground 
  in 
  which 
  it 
  pupates. 
  A 
  local 
  pest, 
  which 
  may 
  at 
  times 
  do 
  

   considerable 
  damage. 
  Said 
  to 
  occur 
  more 
  commonly 
  on 
  areas 
  of 
  black 
  cotton 
  soil."
