  This 
  scale 
  insect 
  has 
  attracted 
  more 
  attention 
  than 
  any 
  other 
  injurious 
  

   insect; 
  and 
  in 
  these 
  days 
  of 
  easy 
  and 
  rapid 
  publication 
  the 
  notices 
  

   regarding 
  it 
  have 
  accumulated 
  at 
  a 
  remarkable 
  rate. 
  The 
  attention 
  of 
  

   the 
  student 
  is 
  called 
  particularly 
  to 
  the 
  accounts 
  and 
  bibhographies 
  by 
  

   Dr 
  Lintner, 
  Dr 
  Howard 
  and 
  his 
  associate, 
  Dr 
  Marlatt, 
  to 
  which 
  the 
  

   appended 
  bibHography 
  is 
  largely 
  supplemental. 
  A 
  few 
  of 
  the 
  most 
  

   important 
  notices 
  cited 
  by 
  the 
  above 
  named 
  writers 
  have 
  been 
  repeated, 
  

   and 
  special 
  attention 
  has 
  been 
  given 
  to 
  the 
  more 
  important 
  articles 
  con- 
  

   cerning 
  this 
  insect 
  in 
  New 
  York 
  state. 
  No 
  attempt 
  has 
  been 
  made 
  to 
  

   include 
  a 
  mass 
  of 
  minor 
  notices 
  relating 
  to 
  this 
  pest 
  in 
  other 
  parts 
  of 
  the 
  

   country 
  or 
  in 
  other 
  countries.
