  The 
  author 
  records 
  a 
  case 
  of 
  one 
  insect 
  laying 
  an 
  egg 
  on 
  that 
  of 
  

   another 
  insect, 
  and 
  of 
  the 
  subsequent 
  development 
  of 
  the 
  parasitic 
  

   larva, 
  not 
  in 
  the 
  egg 
  of 
  the 
  host, 
  but 
  in 
  the 
  larva 
  of 
  the 
  latter. 
  

   This 
  insect 
  was 
  the 
  Ichneumon, 
  Bassus 
  laetatorius, 
  which 
  

   was 
  reared 
  in 
  several 
  instances 
  from 
  the 
  larvae 
  of 
  the 
  

   Syrphid, 
  Baccha 
  clavata. 
  Oviposition 
  by 
  B. 
  laetatorius 
  in 
  the 
  eggs 
  

   of 
  B. 
  clavata 
  was 
  observed, 
  and 
  though 
  the 
  larvae 
  of 
  B. 
  clavata 
  hatched 
  

   normally 
  and 
  grew 
  to 
  maturity, 
  the 
  adults 
  of 
  B. 
  laetatorius 
  issued 
  from 
  

   the 
  pupae, 
  having 
  required 
  about 
  35 
  days 
  to 
  reach 
  the 
  adult 
  stage 
  

   irom 
  the 
  egg. 
  The 
  case 
  is 
  remarkable, 
  since 
  the 
  egg 
  of 
  the 
  Syrphid 
  

   measures 
  only 
  about 
  1 
  mm., 
  while 
  the 
  adult 
  Ichneumon 
  is 
  about 
  8 
  mm. 
  

   in 
  length.

  The 
  Clover 
  Leaf 
  Weevil 
  {Hypera 
  punctata), 
  common 
  in 
  the 
  eastern 
  

   States 
  of 
  America, 
  has 
  recently 
  become 
  abundant 
  in 
  a 
  part 
  of 
  the 
  

   Payette 
  Valley 
  in 
  south-western 
  Idaho. 
  A 
  field 
  of 
  red 
  clover 
  was 
  

   eaten 
  to 
  the 
  ground 
  and 
  surrounding 
  lucerne 
  seriously 
  injured 
  during 
  

   April 
  by 
  the 
  larvae 
  of 
  this 
  insect. 
  The 
  clover 
  and 
  some 
  of 
  the 
  lucerne 
  

   were 
  promptly 
  ploughed 
  to 
  kill 
  the 
  larvae. 
  There 
  is 
  no 
  evidence
