  occurred 
  the 
  preceding 
  two 
  years, 
  but 
  they 
  have 
  invaded 
  new 
  territory, 
  

   and 
  it 
  is 
  doubtful 
  whether 
  their 
  numbers 
  have 
  been 
  reduced.

   [Birch 
  twigs 
  with 
  the 
  petioles 
  occupied 
  by 
  a 
  small 
  curculionid 
  larva 
  were 
  

   received 
  with 
  the 
  following 
  statement 
  from 
  Mr 
  Flint.] 
  The 
  effects 
  

   are 
  very 
  noticeable 
  in 
  the 
  vicinity 
  of 
  Pinehill, 
  Ulster 
  co. 
  and 
  adjacent 
  

   territory. 
  The 
  leaves 
  are 
  mostly 
  wilted 
  and 
  some 
  of 
  them 
  have 
  turned 
  

   brown.

  Cherry

   parts

  The 
  elm 
  leaf 
  beetle 
  is 
  doing 
  considerable 
  

   damage 
  in 
  the 
  river 
  section 
  of 
  this 
  county, 
  but 
  it 
  is 
  not 
  so 
  serious 
  as 
  last 
  

   year. 
  It 
  does 
  not 
  appear 
  to 
  be 
  present 
  any 
  great 
  distance 
  from 
  the 
  river. 
  

   Aug. 
  3. 
  A 
  second 
  brood 
  of 
  elm 
  leaf 
  beetles 
  is 
  now 
  developing. 
  The 
  

   injury 
  to 
  maples 
  in 
  certain 
  parts 
  of 
  this 
  county 
  is 
  irremediable, 
  as 
  in 
  the 
  

   towns 
  of 
  Jewett, 
  Lexington, 
  and 
  also 
  in 
  Worcester 
  and 
  Decatur, 
  Otsego 
  

   CO. 
  The 
  fall 
  web 
  worm 
  [Hyphantria 
  cunea] 
  is 
  present 
  in 
  rather 
  

   ^mall 
  numbers.

  Herkimer 
  county 
  (G. 
  S. 
  Graves, 
  Newport) 
  — 
  More 
  than 
  90% 
  of 
  

   the 
  egg 
  belts 
  of 
  the 
  forest 
  tent-caterpillar 
  [Clisiocampa 
  disstria] 
  

   are 
  on 
  the 
  maple 
  trees. 
  Many 
  of 
  the 
  egg 
  belts 
  are 
  quite 
  irregular 
  in 
  

   form. 
  Oct. 
  16. 
  There 
  do 
  not 
  appear 
  to 
  be 
  more 
  than 
  25% 
  as 
  many 
  

   egg 
  belts 
  as 
  there 
  were 
  last 
  fall.

  " 
  Brown 
  and 
  black 
  woolly 
  bears 
  

   [Pyrrharctia 
  isabellaj 
  are 
  very 
  abundant, 
  even 
  crawling 
  on 
  the 
  

   snow. 
  The 
  pupils 
  in 
  school 
  21 
  of 
  Utica 
  collected 
  11,729 
  egg 
  clusters 
  of 
  

   the 
  forest 
  tent-caterpillar 
  this 
  spring. 
  Ap. 
  17. 
  Appletree 
  tent-caterpillars 
  

   [Clisiocampta 
  americana] 
  were 
  first 
  noticed 
  last 
  Sunday, 
  the 
  

   22d, 
  and 
  since 
  that 
  time 
  they 
  have 
  appeared 
  in 
  considerable 
  numbers, 
  

   particularly 
  on 
  appletrees. 
  Forest 
  tent-caterpillar 
  eggs 
  are 
  practically 
  

   free 
  from 
  the 
  protective 
  covering. 
  Ap. 
  28. 
  Both 
  species 
  of 
  tent-cater- 
  

   pillars 
  are 
  hatching 
  rapidly 
  and 
  in 
  numbers, 
  the 
  forest 
  tent-caterpillars 
  

   appearing 
  four 
  days 
  later 
  than 
  the 
  others.

  All 
  the 
  forest 
  tent- 
  

   caterpillars 
  seen 
  by 
  me 
  on 
  the 
  5th 
  and 
  7th 
  seemed 
  to 
  be 
  alive, 
  and 
  on 
  

   the 
  latter 
  date 
  they 
  were 
  warmed 
  up 
  enough 
  to 
  drop 
  readily 
  

   on 
  threads 
  when 
  the 
  limbs 
  were 
  jarred. 
  The 
  recent 
  cold 
  does 
  not 
  

   appear 
  to 
  have 
  affected 
  them. 
  May 
  10. 
  I 
  examined 
  today 
  500 
  to 
  

   1000 
  clusters 
  of 
  caterpillars 
  of 
  both 
  species 
  and 
  feel 
  justified 
  in 
  saying 
  

   that 
  they 
  were 
  not 
  harmed 
  by 
  the 
  cold 
  weather. 
  I 
  saw 
  in 
  several 
  in- 
  

   stances 
  the 
  cast 
  skins 
  of 
  caterpillars, 
  and 
  at 
  first 
  could 
  not 
  locate 
  their 
  

   present 
  whereabouts, 
  but 
  in 
  each 
  case 
  they 
  were 
  finally 
  found. 
  No 
  cat- 
  

   erpillars 
  have 
  as 
  yet 
  been 
  seen 
  on 
  the 
  maples, 
  which 
  are 
  leafing 
  out 
  very 
  

   slowly. 
  May

  Case-bearers 
  [probably 
  the 
  cigar 
  case-bearer, 
  Cole- 
  

   ophora 
  fletchereUa] 
  are 
  quite 
  numerous 
  on 
  the 
  apple.
