  The 
  next 
  day 
  some 
  recently 
  hatched 
  ones 
  

   found 
  on 
  a 
  tree 
  were 
  transferred 
  to 
  an 
  old 
  leaf, 
  and 
  a 
  fair 
  proportion 
  of 
  

   them 
  completed 
  their 
  transformations. 
  That 
  the 
  larvae 
  actually 
  mature 
  

   on 
  old 
  foliage 
  is 
  rendered 
  certain 
  by 
  the 
  development 
  of 
  a 
  large 
  second 
  

   brood 
  on 
  a 
  number 
  of 
  trees 
  which 
  had 
  been 
  scarcely 
  injured 
  by 
  the 
  first 
  

   brood, 
  and 
  by 
  the 
  continued

   In 
  one 
  instance, 
  when 
  food 
  had 
  not 
  been 
  given 
  them 
  in 
  three 
  days 
  and 
  

   all 
  the 
  leaves 
  had 
  been 
  eaten, 
  — 
  upon 
  opening 
  the 
  box 
  containing 
  them, 
  

   a 
  larva 
  was 
  seen 
  devouring 
  a 
  living 
  pupa 
  : 
  it 
  had 
  already 
  eaten 
  away 
  a 
  

   large 
  portion 
  of 
  the 
  dorsal 
  wall 
  of 
  its 
  thorax. 
  

  

  The 
  beetles, 
  as 
  before 
  noted, 
  are 
  ravenous 
  feeders 
  before 
  oviposition 
  — 
  

   commonly 
  eating 
  large 
  holes 
  in 
  the 
  leaves. 
  In 
  one 
  case 
  observed 
  August 
  

   31st, 
  they 
  had 
  been 
  skeletonizing 
  an 
  old 
  leaf 
  in 
  a 
  manner 
  very 
  similar 
  to 
  

   that 
  of 
  the 
  young 
  larvae. 
  The 
  leaf 
  was 
  unusually 
  dry 
  and 
  somewhat 
  

   dusty, 
  and 
  its 
  unpalatable 
  condition 
  may 
  have 
  been 
  the 
  cause 
  of 
  the 
  

   departure 
  from 
  their 
  ordinary 
  feeding 
  habit.
