  The 
  sad 
  condition 
  of 
  the 
  shade-trees 
  in 
  many 
  of 
  our 
  larger 
  cities, 
  is 
  

   exciting 
  considerable 
  attention 
  and 
  especially 
  is 
  this 
  true 
  where 
  the 
  elm- 
  

   leaf 
  beetle, 
  Galenicella 
  luteola, 
  has 
  become 
  familiar 
  through 
  its 
  defolia- 
  

   tion 
  of 
  numerous 
  elms, 
  the 
  recent 
  destruction 
  of 
  many 
  fine 
  trees 
  in 
  the 
  

   Hudson 
  river 
  valley, 
  and 
  the 
  doomed 
  condition 
  of 
  thousands 
  of 
  others. 
  

   As 
  if 
  the 
  long 
  list 
  of 
  insect 
  pests 
  preying 
  upon 
  the 
  foliage 
  or 
  burrow- 
  

   ing 
  within 
  the 
  bark 
  and 
  sap-wood 
  of 
  the 
  elms 
  was 
  not 
  sufficiently 
  ex- 
  

   tended, 
  another 
  species 
  has 
  recently 
  come 
  over 
  from 
  abroad 
  and 
  is 
  

   rapidly 
  extending 
  its 
  range, 
  and 
  fast 
  making 
  itself 
  a 
  public 
  nuisance 
  

   from 
  its 
  blackening 
  the 
  foliage 
  and 
  branches 
  and 
  also 
  the 
  side 
  walks 
  

   beneath 
  with 
  its 
  vile 
  excreta. 
  

  

  Introduced 
  from 
  Abroad. 
  

   The 
  elm-tree 
  bark-louse, 
  Gossyparia 
  ulmi 
  (Geoff.), 
  like 
  a 
  large 
  number 
  

   of 
  our 
  most 
  common 
  and 
  injurious 
  insects, 
  is 
  an 
  introduced 
  species. 
  

   The 
  precise 
  manner 
  and 
  time 
  of 
  introduction 
  into 
  this 
  country 
  are 
  not 
  

   known 
  and 
  probably 
  will 
  never 
  be 
  definitely 
  ascertained. 
  It 
  was 
  first 
  

   brought 
  to 
  the 
  notice 
  of 
  the 
  U. 
  S. 
  Department 
  of 
  Agriculture 
  in 
  1884 
  

   through 
  Mr. 
  Charles 
  Fremd, 
  of 
  Rye, 
  Westchester 
  Co., 
  N. 
  Y., 
  who 
  at 
  that 
  

   time 
  complained 
  of 
  the 
  elms 
  in 
  his 
  nursery 
  being 
  troubled 
  with 
  thousands 
  

   of 
  a 
  red-looking 
  mealy 
  bug. 
  The 
  insect 
  (represented 
  in 
  figure 
  2 
  of 
  

   plate 
  XIV) 
  had 
  probably 
  been 
  brought 
  over 
  on 
  some 
  nursery 
  stock 
  

   several 
  years 
  prior 
  to 
  its 
  discovery 
  at 
  Rye. 
  This 
  importation 
  is 
  another 
  

   illustration 
  of 
  the 
  ease 
  with 
  which 
  insects 
  can 
  be 
  introduced 
  from 
  other 
  

   countries 
  on 
  nursery 
  stock. 
  

  

  History 
  of 
  the 
  Insect. 
  

   This 
  bark-louse 
  was 
  not 
  determined 
  at 
  the 
  time 
  it 
  was 
  received 
  by 
  

   the 
  U. 
  S. 
  Department 
  of 
  Agriculture 
  from 
  Mr. 
  Fremd, 
  nor 
  in 
  other 
  send-
