  pupae 
  were 
  abundant. 
  Having 
  completed 
  their 
  transformations, 
  August 
  

   10 
  the 
  recently 
  emerged 
  beetles 
  had 
  seriously 
  injured 
  the 
  tender 
  leaves 
  

   unfolding 
  on 
  trees 
  that 
  had 
  been 
  defoliated 
  earlier 
  by 
  the 
  first 
  brood, 
  

   while 
  the 
  second 
  brood 
  of 
  larvae 
  had 
  begun 
  their 
  destructive 
  work. 
  

   September 
  8, 
  they 
  had 
  completed 
  their 
  growth 
  and 
  many 
  had 
  transformed 
  

   to 
  pupae. 
  The 
  spraying 
  operations 
  conducted 
  by 
  the 
  civic 
  authorities 
  

   at 
  Albany 
  against 
  this 
  pest 
  prevented 
  satisfactory 
  observations 
  later 
  in 
  

   the 
  season. 
  However, 
  on 
  visiting 
  the 
  neighboring 
  city 
  of 
  Troy, 
  a 
  number 
  

   of 
  bright 
  living 
  pupae 
  were 
  found 
  on 
  the 
  remarkably 
  late 
  date 
  of 
  Novem- 
  

   ber 
  1 
  6 
  in 
  the 
  protected 
  hollow 
  of 
  a 
  tree. 
  This 
  should 
  be 
  accepted 
  as 
  

   incontrovertible 
  evidence 
  of 
  the 
  occurrence 
  of 
  three 
  generations 
  annually 
  

   in 
  that 
  city. 
  

  

  The 
  slow 
  but 
  continued 
  spread 
  of 
  this 
  insect 
  recorded 
  in 
  preceding 
  

   reports, 
  was 
  shown 
  the 
  present 
  year 
  by 
  the 
  appearance 
  of 
  the 
  insect 
  in 
  

   force 
  on 
  English 
  elms 
  in 
  Washington 
  park, 
  Albany 
  (in 
  the 
  central 
  portion 
  

   of 
  the 
  city), 
  hitherto 
  exempt 
  from 
  its 
  attack. 
  Another 
  noticeable 
  feature 
  

   of 
  the 
  insect's 
  presence 
  was 
  the 
  marked 
  injury 
  to 
  the 
  American 
  elms 
  in 
  

   portions 
  of 
  the 
  city 
  where 
  the 
  pest 
  has 
  been 
  established 
  for 
  several 
  years. 
  

   They 
  were 
  not, 
  as 
  a 
  rule, 
  so 
  badly 
  affected 
  as 
  the 
  English 
  elms. 
  The 
  

   greater 
  part 
  of 
  the 
  foliage 
  of 
  the 
  affected 
  American 
  elms 
  was 
  partly 
  skele- 
  

   tonized 
  and 
  injured 
  to 
  the 
  extent 
  that 
  it 
  presented 
  a 
  yellowish, 
  unhealthy 
  

   appearance, 
  though 
  not 
  many 
  of 
  the 
  leaves 
  dropped 
  as 
  in 
  the 
  case 
  of 
  

   the 
  more 
  seriously 
  injured 
  English 
  elms. 
  

  

  Blissus 
  leucopterus 
  Say 
  

   Chinch-bug 
  

  

  This 
  insect 
  was 
  discovered 
  in 
  the 
  autumn 
  of 
  1896 
  on 
  the 
  farm 
  of 
  J. 
  N. 
  

   Hasvvell, 
  i 
  mile 
  to 
  the 
  southwest 
  of 
  the 
  city 
  of 
  Watervliet, 
  N. 
  Y., 
  in 
  

   Hungarian 
  grass 
  and 
  timothy. 
  This 
  year 
  (1897) 
  it 
  appeared 
  on 
  the 
  same 
  

   farm, 
  in 
  timothy, 
  but 
  not 
  in 
  clover 
  or 
  any 
  other 
  crop. 
  It 
  was 
  not 
  very 
  

   injurious 
  so 
  far 
  as 
  known.

  aphididae 
  

  

  The 
  present 
  year 
  has 
  been 
  remarkable 
  for 
  the 
  abundance 
  of 
  various 
  

   aphides 
  or 
  ])lant 
  lice 
  on 
  many 
  different 
  plants. 
  In 
  some 
  cases 
  their 
  injuries 
  

   were 
  very 
  serious, 
  in 
  others, 
  natural 
  enemies 
  prevented 
  their 
  becoming 
  

   unduly 
  abundant. 
  

  

  Pemphigus 
  populi-transversus 
  Riley. 
  Attention 
  was 
  drawn 
  to 
  

   this 
  interesting 
  species 
  by 
  the 
  characteristic 
  galls 
  it 
  produced 
  on 
  the
