﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST 
  237 
  

  

  In 
  187 
  1, 
  when 
  the 
  potato 
  beetle 
  had 
  for 
  the 
  first 
  time 
  invaded 
  the 
  

   Dominion 
  of 
  Canada, 
  and 
  had 
  not 
  yet 
  entered 
  New 
  York, 
  Prof 
  Riley 
  

   reported 
  that 
  this 
  beetle 
  was 
  proving 
  to 
  be 
  an 
  efficient 
  enemy 
  of 
  the 
  new 
  

   pest 
  in 
  several 
  of 
  the 
  western 
  States; 
  and 
  that 
  although, 
  it 
  had 
  pre- 
  

   viously 
  been 
  rare 
  in 
  the 
  State 
  of 
  Missouri 
  it 
  had 
  suddenly 
  become 
  

   abundant 
  and 
  was 
  actively 
  engaged 
  in 
  destroying 
  both 
  the 
  eggs 
  and 
  the 
  

   larvae 
  of 
  the 
  potato 
  beetle. 
  

  

  This 
  beetle 
  has 
  a 
  distribution 
  throughout 
  the 
  United 
  States 
  which 
  is 
  

   almost 
  co-extensive 
  with 
  that 
  of 
  the 
  insect 
  upon 
  which 
  it 
  specially 
  preys. 
  

   Unfortunately, 
  although 
  so 
  abundant 
  oftimes, 
  and 
  aided 
  by 
  nearly 
  two 
  

   score 
  of 
  other 
  species, 
  it 
  is 
  not 
  able 
  to 
  greatly 
  reduce 
  the 
  number 
  of 
  the 
  

   greedy 
  and 
  insatiable 
  Doryphora. 
  

  

  Plagionotus 
  speciosus 
  (Say).
