  Hering 
  (Stett. 
  JEnt. 
  Zeity., 
  1891, 
  p. 
  224) 
  first 
  

   noted 
  that 
  Herms 
  had 
  found 
  the 
  dusty 
  grey-green 
  larva? 
  of 
  the 
  second 
  

   brood 
  at 
  the 
  end 
  of 
  June 
  and 
  beginning 
  of 
  July, 
  in 
  the 
  park 
  of 
  

   Hohenkrug, 
  feeding 
  on 
  the 
  flowers 
  of 
  Crepis 
  tectorum, 
  in 
  the 
  same 
  way 
  

   as 
  the 
  larva? 
  of 
  Geina 
  didactyla 
  do 
  on 
  those 
  of 
  Geitm 
  rivale. 
  Hofmann 
  

   repeats 
  this, 
  but 
  adds 
  Crepis 
  virens 
  as 
  a 
  foodplant, 
  and 
  notes 
  that 
  the 
  

   larvae 
  of 
  the 
  first 
  brood, 
  occurring 
  in 
  early 
  spring, 
  must 
  have, 
  in 
  any 
  

   case, 
  a 
  different 
  habit; 
  he 
  opines 
  that 
  they 
  possibly 
  live 
  spun-up 
  within 
  

   the 
  central 
  shoot 
  of 
  the 
  young 
  plant. 
  Durrant

  two 
  larvae

   early 
  August,

  1898, 
  from, 
  it 
  is 
  believed, 
  Picris 
  Irieracoides, 
  but 
  

   one 
  small 
  larva 
  was 
  injured, 
  and, 
  although 
  the 
  other 
  pupated, 
  the 
  

   pupa 
  produced 
  an 
  ichneumon.
