  ings 
  of 
  the 
  same 
  by 
  Mr. 
  J. 
  G. 
  Jack, 
  from 
  Cambridge, 
  in 
  1887 
  and 
  1888. 
  

   In 
  the 
  autumn 
  of 
  1888, 
  it 
  was 
  discovered 
  in 
  several 
  localities 
  in 
  the 
  City 
  

   of 
  Washington. 
  The 
  following 
  year 
  a 
  more 
  complete 
  series 
  of 
  its 
  stages 
  

   having 
  been 
  obtained 
  from 
  Mr, 
  Jack, 
  it 
  was 
  identified 
  at 
  the 
  Department 
  

   with 
  the 
  European 
  Gossyparia 
  ulmi. 
  In 
  July 
  of 
  the 
  previous 
  year 
  (1888) 
  

   it 
  had 
  been 
  received 
  by 
  me 
  from 
  Marlboro 
  and 
  Albany, 
  N. 
  Y., 
  and 
  

   observed 
  by 
  Professor 
  Perkins 
  at 
  Burlington, 
  Vermont. 
  It 
  was 
  also 
  

   detected 
  about 
  this 
  date 
  in 
  New 
  York 
  City 
  by 
  Mr. 
  Henry 
  Edwards, 
  and 
  

   in 
  1890 
  it 
  was 
  sent 
  to 
  Washington 
  from 
  Brighton, 
  Mass. 
  Some 
  young 
  

   trees 
  at 
  Palo 
  Alto, 
  California, 
  were 
  seriously 
  affected 
  by 
  this 
  insect 
  in 
  

   1893. 
  The 
  next 
  year 
  it 
  occured 
  abundantly 
  at 
  Ghent, 
  N. 
  Y. 
  In 
  1895, 
  

   Prof. 
  G. 
  C. 
  Davis 
  found 
  it 
  numerous 
  on 
  the 
  elms 
  of 
  the 
  Michigan 
  Agri- 
  

   cultural 
  College, 
  and 
  badly 
  infested 
  trees 
  were 
  reported 
  by 
  Prof, 
  F. 
  H. 
  

   Hillman 
  at 
  Carson 
  City, 
  Nevada. 
  About 
  this 
  time 
  it 
  made 
  its 
  appear- 
  

   ance 
  at 
  Amherst 
  and 
  Brookline, 
  Mass. 
  The 
  present 
  year 
  it 
  was 
  re- 
  

   ceived 
  by 
  me 
  from 
  Catskill, 
  and 
  observation 
  has 
  shown 
  it 
  to 
  be 
  quite 
  

   largely 
  distributed 
  in 
  the 
  vicinity 
  of 
  Albany 
  and 
  Troy 
  in 
  this 
  state. 
  

  

  Its 
  Distribution. 
  

  

  It 
  will 
  be 
  seen 
  from 
  the 
  above 
  that 
  this 
  insect 
  is 
  now 
  known 
  to 
  occur 
  

   in 
  six 
  States 
  in 
  the 
  Union 
  besides 
  the 
  District 
  of 
  Columbia. 
  In 
  Massa- 
  

   chusetts 
  it 
  appears 
  to 
  be 
  extensively 
  distributed 
  over 
  the 
  state, 
  as 
  published 
  

   in 
  a 
  recent 
  notice 
  of 
  the 
  insect 
  by 
  Mr. 
  Kirkland. 
  It 
  is 
  quite 
  probable 
  

   that 
  it 
  has 
  already 
  been 
  introduced 
  in 
  the 
  adjoining 
  states 
  of 
  Rhode 
  

   Island 
  and 
  Connecticut. 
  From 
  the 
  occurrence 
  of 
  the 
  pest 
  at 
  Burlington, 
  

   Vt., 
  there 
  is 
  little 
  doubt 
  but 
  that 
  it 
  will 
  soon 
  invade 
  New 
  Hampshire 
  and 
  

   Maine, 
  if 
  it 
  has 
  not 
  already 
  done 
  so. 
  It 
  is 
  known 
  to 
  occur 
  in 
  several 
  

   localities 
  along 
  the 
  Hudson 
  river 
  valley 
  from 
  the 
  City 
  of 
  New 
  York 
  to 
  

   Troy. 
  In 
  the 
  upper 
  portion 
  of 
  this 
  district, 
  the 
  insect 
  has 
  been 
  found 
  so 
  

   abundant 
  and 
  generally 
  distributed 
  that 
  the 
  same 
  condition 
  will 
  probably 
  

   soon 
  be 
  reported 
  for 
  the 
  lower 
  Hudson. 
  

  

  The 
  other 
  recorded 
  occurrences 
  of 
  this 
  insect 
  indicate 
  a 
  wide 
  distribu- 
  

   tion 
  for 
  it 
  in 
  the 
  future, 
  — 
  ranging 
  from 
  the 
  Atlantic 
  to 
  the 
  Pacific 
  and, 
  

   at 
  least, 
  from 
  about 
  the 
  latitude 
  of 
  Washington, 
  D. 
  C, 
  to 
  near 
  the 
  

   Canadian 
  border. 
  

  

  Injuries 
  by 
  this 
  Pest. 
  

  

  It 
  is 
  impossible 
  to 
  estimate 
  even 
  approximately 
  the 
  damage 
  caused 
  by 
  

   this 
  insect 
  in 
  its 
  eastern 
  distribution, 
  associated 
  as 
  it 
  largely 
  is 
  with 
  the 
  

   destructive 
  elm-leaf 
  beetle.
