  parts 
  of 
  the 
  city, 
  I 
  find 
  that 
  large 
  patches 
  of 
  grass 
  in 
  many 
  of 
  the 
  lawns 
  

   were 
  entirely 
  destroyed 
  and 
  one 
  covering 
  a 
  large 
  area 
  was 
  entirely 
  ruined 
  

   except 
  the 
  front 
  portion. 
  The 
  grass 
  had 
  been 
  entirely 
  eaten 
  away 
  and 
  the 
  

   roots 
  killed, 
  hardly 
  a 
  spear 
  of 
  grass 
  remained, 
  nothing 
  but 
  chickweed 
  and 
  

   other 
  weeds 
  growing. 
  Most 
  of 
  the 
  caterpillars 
  were 
  found 
  resting 
  on 
  the 
  

   ground, 
  where 
  they 
  apparently 
  feed, 
  cutting 
  off 
  the 
  grass 
  below 
  the 
  crown 
  

   and 
  thus 
  killing 
  it. 
  They 
  select 
  blue 
  grass 
  largely, 
  which 
  constitutes 
  the 
  

   * 
  major 
  proportion 
  of 
  the 
  lawns 
  in 
  Buffalo. 
  The 
  pupae 
  were 
  found 
  in 
  an 
  

   upright 
  position 
  just 
  beneath 
  the 
  surface. 
  The 
  insect 
  apparently 
  hiber- 
  

   nates 
  in 
  all 
  stages 
  of 
  development. 
  Many 
  of 
  the 
  pupae 
  were 
  parasitized 
  

   or 
  were 
  otherwise 
  diseased. 
  Oct. 
  i8, 
  1899, 
  lime 
  applied 
  in 
  large 
  enough 
  

   quantities 
  to 
  kill 
  the 
  grass 
  had 
  little 
  or 
  no 
  effect 
  on 
  the 
  insect. 
  March 
  

   31 
  I 
  took 
  about 
  50 
  specimens 
  of 
  Desmocerus 
  palliatus 
  boring 
  

   in 
  Sambucus 
  planted 
  for 
  a 
  hedge. 
  Many 
  of 
  the 
  plants 
  were 
  de- 
  

   stroyed, 
  four 
  and 
  five 
  larvae 
  being 
  taken 
  from 
  the 
  base 
  of 
  a 
  single 
  one. 
  

   The 
  mines 
  were 
  so 
  close 
  together 
  in 
  some 
  instances 
  that 
  all 
  the 
  wood 
  was 
  

   destroyed, 
  and 
  the 
  bush 
  would 
  break 
  off 
  at 
  the 
  base 
  while 
  it 
  was 
  being 
  

   trimmed. 
  A 
  young 
  sugar 
  maple 
  which 
  had 
  died 
  in 
  the 
  summer 
  of 
  1899. 
  

   was 
  found 
  this 
  spring 
  to 
  be 
  completely 
  mined 
  by 
  a 
  flat-headed 
  borer,, 
  

   probably 
  Dicerca 
  divaricata. 
  The 
  mines 
  were 
  old 
  and 
  deserted. 
  

   The 
  tree 
  came 
  out 
  in 
  full 
  leaf 
  in 
  the 
  spring 
  of 
  1899 
  but 
  soon 
  withered 
  

   and 
  died. 
  Ap. 
  17. 
  I 
  have 
  watched 
  the 
  tussock 
  moth 
  [Notolophus 
  

   leucostigma] 
  very 
  closely 
  since 
  1895 
  and 
  have 
  discovered 
  but 
  one 
  

   brood 
  in 
  a 
  season. 
  The 
  recently 
  hatched 
  young 
  were 
  observed 
  on 
  an 
  

   egg 
  mass 
  early 
  in 
  October 
  in 
  1896, 
  but 
  that 
  night 
  they 
  were 
  killed 
  by 
  a 
  

   heavy 
  frost. 
  Ap. 
  19. 
  I 
  read 
  an 
  article 
  in 
  the 
  morning 
  papers 
  that 
  the 
  

   tent-caterpillars 
  had 
  all 
  been 
  killed 
  at 
  Hamburg 
  by 
  the 
  cold 
  weather; 
  so 
  

   I 
  selected 
  that 
  locality 
  for 
  making 
  observations. 
  Appletree 
  tent- 
  caterpil- 
  

   lars 
  [Clisiocampa 
  americana] 
  were 
  in 
  a 
  perfectly 
  healthy 
  condi- 
  

   tion 
  and 
  none 
  the 
  worse 
  for 
  the 
  cold 
  weather. 
  No 
  forest 
  tent- 
  caterpillars 
  

   [Clisiocampa 
  disstria] 
  could 
  be 
  found.

  I 
  col- 
  

   lected 
  the 
  larvae 
  of 
  what 
  is 
  probably 
  Cyllene 
  picta 
  boring 
  in 
  young 
  

   hickory.

  the 
  adults 
  and 
  pupae 
  ofMagdalis 
  armicollis 
  

   were 
  taken 
  in 
  their 
  mines 
  in 
  white 
  elm. 
  The 
  scholars 
  attending 
  one 
  

   school 
  gathered 
  75,000 
  egg 
  masses 
  (over 
  7 
  bushels) 
  of 
  the 
  white 
  

   marked 
  tussock 
  moth 
  last 
  week. 
  May

  The 
  larvae 
  of 
  M

   have 
  nearly 
  all 
  transformed 
  to 
  pupae. 
  The 
  elm-borer, 
  Saperda

  occurs 
  in 
  the

  A
