  respondents, 
  Mr. 
  W. 
  R. 
  Walton, 
  of 
  Middletown, 
  N. 
  Y., 
  has 
  been 
  fortu- 
  

   nate 
  in 
  his 
  collection 
  of 
  it 
  and 
  has 
  kindly 
  contributed 
  a 
  number 
  of 
  exam- 
  

   ples 
  to 
  the 
  State 
  Collection. 
  He 
  also 
  has 
  been 
  successful 
  in 
  breeding 
  

   from 
  it 
  the 
  beautiful 
  Lepidopterous 
  parasite, 
  Euclemensia 
  Bassettella 
  

   (Clemens), 
  with 
  which 
  it 
  is 
  so 
  frequently 
  infested 
  and 
  of 
  which 
  he 
  has 
  

   made 
  excellent 
  colored 
  drawings 
  in 
  its 
  several 
  stages 
  (PI. 
  V, 
  figs. 
  2-7). 
  

   From 
  Kermes 
  taken 
  from 
  scrub 
  oak 
  in 
  the 
  latter 
  part 
  of 
  December, 
  he 
  

   obtained 
  the 
  moth 
  toward 
  the 
  last 
  of 
  the 
  following 
  June. 
  The 
  larger 
  

   number 
  of 
  the 
  mature 
  Kermes 
  were 
  found 
  to 
  be 
  infested 
  by 
  the 
  parasite. 
  

  

  The 
  Elm-Tree 
  Bark-Louse. 
  

  

  Gossyparia 
  ulmi 
  (Geoffrey), 
  an 
  European 
  Coccus, 
  feeding 
  on 
  most 
  of 
  

   the 
  varieties 
  of 
  the 
  European 
  and 
  American 
  elms, 
  was 
  first 
  noticed 
  in 
  

   this 
  country 
  at 
  Rye, 
  Westchester 
  county, 
  N. 
  Y., 
  in 
  June 
  of 
  1884. 
  (See 
  

   Howard 
  in 
  Insect 
  Lifi, 
  ii, 
  1889, 
  pp. 
  34-41). 
  Examples 
  of 
  it 
  were 
  

   brought 
  to 
  me 
  from 
  Marlboro, 
  Ulster 
  county, 
  in 
  July 
  of 
  1888. 
  Since 
  

   that 
  time, 
  it 
  appears 
  to 
  have 
  become 
  distributed 
  in 
  different 
  portions 
  of 
  

   the 
  State, 
  and 
  to 
  have 
  planted 
  itself 
  in 
  several 
  localities 
  in 
  the 
  vicinity 
  of 
  

   Albany. 
  In 
  May 
  and 
  again 
  in 
  June, 
  it 
  was 
  brought 
  to 
  me 
  from 
  Loudon- 
  

   ville, 
  Albany 
  county, 
  and 
  in 
  June 
  of 
  the 
  same 
  year, 
  from 
  two 
  places 
  in 
  

   the 
  city 
  of 
  Albany, 
  and 
  also 
  from 
  Catskill, 
  Greene 
  county, 
  40 
  miles 
  to 
  

   the 
  southward. 
  

  

  In 
  June 
  of 
  the 
  present 
  year, 
  Mr. 
  J. 
  B. 
  Washburn, 
  brought 
  a 
  hmb 
  of 
  

   elm 
  from 
  his 
  grounds 
  at 
  Delmar, 
  Albany 
  county, 
  bearing 
  dense 
  patches 
  

   of 
  the 
  Coccid. 
  It 
  was 
  blackened 
  to 
  a 
  degree 
  that 
  indicated 
  the 
  abundant 
  

   presence 
  of 
  the 
  insect 
  the 
  preceding 
  year. 
  The 
  tree 
  — 
  a 
  young 
  one 
  — 
  of 
  

   about 
  three 
  inches 
  diameter 
  of 
  trunk, 
  was 
  infested 
  both 
  upon 
  the 
  trunk 
  

   and 
  the 
  limbs. 
  Other 
  elms 
  upon 
  his 
  grounds 
  were 
  not 
  infested. 
  The 
  

   scales 
  were 
  apparently 
  about 
  full-grown, 
  but 
  no 
  young 
  had 
  yet 
  been 
  

   given 
  out. 
  

  

  A 
  large 
  number 
  of 
  trees 
  in 
  the 
  city 
  of 
  Albany, 
  are 
  at 
  the 
  present 
  time 
  

   (in 
  August), 
  showing 
  severe 
  and 
  injurious 
  attack 
  from 
  this 
  insect. 
  The 
  

   leaves 
  are 
  blackened 
  by 
  their 
  secretions, 
  and 
  some 
  of 
  the 
  branches 
  

   whitened 
  by 
  their 
  abundant 
  presence. 
  Their 
  larvae, 
  about 
  half-grown, 
  are 
  

   to 
  be 
  seen 
  in 
  large 
  numbers 
  in 
  the 
  crotches 
  of 
  the 
  smaller 
  twigs, 
  on 
  the 
  

   lower 
  surface 
  of 
  the 
  leaves, 
  and 
  in 
  the 
  crevices 
  of 
  the 
  bark. 
  The 
  infested 
  

   trees 
  are 
  mainly 
  the 
  Scotch 
  elm, 
  Uhnus 
  inontana. 
  

  

  The 
  insect 
  is 
  also 
  quite 
  generally 
  distributed 
  in 
  Troy 
  — 
  six 
  miles 
  to 
  

   the 
  north 
  of 
  Albany, 
  where 
  in 
  combination 
  with 
  the 
  attack 
  of 
  the 
  elm-
