  about 
  half 
  an 
  inch 
  in 
  diameter, 
  each 
  contain-

  from 
  50 
  to 
  over 
  100 
  eggs. 
  

  

  It 
  is 
  not 
  expected 
  that 
  the 
  above 
  recorded 
  flights 
  in 
  cities 
  and 
  

   villages 
  will 
  be 
  followed 
  by 
  extensive 
  injuries 
  another 
  season, 
  since 
  

   it 
  is 
  very 
  probable 
  that 
  the 
  English 
  sparrows 
  destroyed 
  many 
  of 
  

   the 
  adults 
  before 
  there 
  was 
  an 
  opportunity 
  for 
  the 
  deposition 
  of 
  

   eggs. 
  

  

  Spruce 
  gall 
  aphid 
  (Chermes 
  abaetis 
  Linn.) 
  . 
  This 
  intro- 
  

   duced, 
  widely 
  distributed 
  species 
  has 
  been 
  the 
  cause 
  of 
  an 
  unusual 
  

   number 
  of 
  complaints 
  in 
  New 
  York 
  State. 
  Mr 
  John 
  Herliky, 
  

   arboriculturist 
  of 
  Brooklyn, 
  writing 
  under 
  the 
  date 
  of 
  June 
  22d 
  

   stated 
  that 
  many 
  Norway 
  spruce 
  trees 
  throughout 
  Prospect 
  park, 
  

   and 
  in 
  fact 
  in 
  different 
  parts 
  of 
  that 
  section 
  of 
  the 
  State, 
  have 
  been

  dying 
  of 
  late. 
  Specimens 
  were 
  submitted 
  for 
  examination 
  and 
  

   were 
  found 
  to 
  contain 
  a 
  few 
  of 
  the 
  characteristic 
  galls 
  of 
  this 
  in- 
  

   sect 
  and, 
  in 
  addition, 
  an 
  apparently 
  undescribed 
  injury. 
  Numerous 
  

   subglobular, 
  aborted 
  buds 
  were 
  found 
  here 
  and 
  there 
  at 
  the 
  base 
  

   of 
  the 
  branches 
  or 
  at 
  the 
  base 
  of 
  new 
  growth 
  and 
  on 
  investigation 
  

   were 
  found 
  to 
  contain 
  numerous 
  small, 
  light 
  brown 
  apbids. 
  It 
  is 
  

   probable 
  that 
  these 
  aphids 
  entered 
  the 
  developing 
  buds 
  the 
  preced- 
  

   ing 
  year 
  and, 
  on 
  account 
  of 
  their 
  abundance, 
  prevented 
  the 
  usual 
  

   growth 
  and 
  the 
  development 
  of 
  the 
  normal 
  type 
  of 
  gall. 
  An 
  ex- 
  

   amination, 
  at 
  this 
  time, 
  of 
  spruces 
  in 
  Albany 
  showed 
  that 
  these 
  trees 
  

   likewise, 
  in 
  addition 
  to 
  the 
  typical 
  galls 
  produced 
  by 
  this 
  aphid, 
  

   bore 
  the 
  subglobular 
  dead 
  buds 
  inhabited 
  by 
  numerous 
  aphids 
  de- 
  

   scribed 
  above. 
  An 
  examination 
  of 
  infested 
  trees 
  in 
  Albany 
  the 
  

   latter 
  part 
  of 
  September 
  showed 
  that 
  the 
  dead 
  buds 
  described
