  however, 
  they 
  were 
  largely 
  aided 
  by 
  other 
  members 
  of 
  their 
  

   family, 
  which 
  were 
  also 
  unusually 
  abundant, 
  among 
  which 
  may 
  

   be 
  named 
  : 
  Melanoplus 
  femoratus, 
  Circotettix 
  verrucidosa, 
  Cam- 
  

   nula 
  pellucid 
  a, 
  Dissosieira 
  Carolina, 
  and 
  Ohortophaga 
  viri- 
  

   difasciata.

  The 
  elm-leaf 
  beetle, 
  Galerucella 
  xanthomelama 
  (Schr.) 
  * 
  has 
  been 
  

   very 
  injurious 
  in 
  Dutchess 
  county. 
  During 
  the 
  month 
  of 
  

   July 
  the 
  elms 
  were 
  covered 
  with 
  the 
  beetles 
  and 
  lost 
  

   most 
  of 
  their 
  foliage. 
  The 
  season 
  has 
  probably 
  favored 
  

   their 
  multiplication. 
  Prof. 
  J. 
  B. 
  Smith 
  reports 
  that 
  trees 
  

   in 
  New 
  Brunswick, 
  N. 
  J., 
  suffered 
  more 
  than 
  ever 
  from 
  

   them, 
  and 
  in 
  some 
  cases 
  not 
  a 
  leaf 
  remained 
  upon 
  them 
  by 
  

   the 
  middle 
  of 
  July. 
  In 
  many 
  places 
  the 
  ground 
  was 
  covered 
  

   with 
  the 
  fallen 
  leaves 
  as 
  in 
  autumn 
  (Entomological 
  News, 
  iv, 
  

   1893, 
  p. 
  229). 
  

  

  The 
  tussock 
  caterpillar 
  of 
  the 
  vaporer 
  moth, 
  Orgyia 
  leucostigma 
  

   (Sm.-x^bb.) 
  proved 
  a 
  veritable 
  plague 
  in 
  Albany 
  during 
  the 
  month 
  

   of 
  July. 
  Fruit 
  trees 
  in 
  gardens 
  were 
  badly 
  eaten 
  by 
  it, 
  while 
  of 
  

   many 
  of 
  the 
  elms 
  and 
  horse-chestnuts 
  the 
  foliage 
  was 
  entirely 
  

   destroyed. 
  From 
  present 
  appearances 
  a 
  number 
  of 
  the 
  trees 
  

   that 
  suffered 
  the 
  most 
  will 
  die 
  from 
  the 
  effect 
  of 
  their 
  defolia- 
  

   tion. 
  The 
  attack 
  was 
  somewhat 
  local 
  : 
  at 
  times, 
  a 
  single 
  isolated 
  

   tree 
  in 
  a 
  row 
  of 
  elms 
  would 
  be 
  attacked, 
  and 
  again, 
  nearly 
  all 
  

   the 
  trees 
  ranging 
  on 
  one 
  side 
  of 
  a 
  block. 
  The 
  explanation 
  of 
  this 
  

   may 
  be, 
  that 
  in 
  such 
  instances, 
  no 
  care 
  had 
  been 
  taken 
  to 
  remove 
  

   the 
  egg-clusters 
  the 
  preceding 
  year 
  from 
  the 
  trunks 
  and 
  main 
  

   limbs 
  of 
  the 
  trees 
  or 
  from 
  beneath 
  fence 
  and 
  wall 
  copings 
  

   and 
  pills 
  of 
  the 
  houses 
  — 
  the 
  importance 
  of 
  which, 
  as 
  the 
  

   chief 
  protection 
  against 
  the 
  ravages 
  of 
  this 
  insect, 
  has 
  been 
  

   repeatedly 
  urged 
  upon 
  our 
  citizens. 
  The 
  application 
  of 
  bands 
  of 
  

   loose 
  cotton 
  to 
  the 
  trunks 
  of 
  trees 
  subject 
  to 
  its 
  attack 
  has 
  been 
  

   largely 
  resorted 
  to, 
  but 
  it 
  should 
  be 
  borne 
  in 
  mind 
  that 
  this 
  will 
  

   only 
  serve 
  as 
  a 
  preventive 
  when 
  there 
  are 
  no 
  egg-clusters 
  or 
  

   caterpillars 
  on 
  the 
  tree 
  or 
  when 
  the 
  tree 
  is 
  not 
  exposed 
  to 
  the 
  

   dropping 
  of 
  hungry 
  caterpillars 
  from 
  overhanging 
  infested 
  

   branches. 
  To 
  trees 
  already 
  infested, 
  either 
  by 
  the 
  eggs 
  or 
  the 
  

  

  • 
  Galeruca 
  xanthomehvna 
  of 
  former 
  reports.
