  A 
  Hght 
  trap, 
  which 
  the 
  American 
  Sugar 
  Beet 
  Company 
  used 
  with 
  

   phenomenal 
  success, 
  is 
  described 
  and 
  figured. 
  The 
  trap 
  is 
  constructed 
  

   of 
  a 
  shallow 
  galvanized 
  iron 
  pan 
  about 
  4 
  feet 
  in 
  diameter, 
  set 
  on 
  a 
  plat- 
  

   form 
  a 
  few 
  feet 
  above 
  the 
  ground. 
  Over 
  the 
  pan, 
  which 
  contains 
  oil, 
  

   is 
  hung 
  a 
  gas 
  burner 
  enclosed 
  in 
  a 
  globe 
  and 
  connected 
  with 
  a 
  tank 
  

   within 
  the 
  frame, 
  in 
  which 
  acetylene 
  gas 
  is 
  generated. 
  On 
  one 
  

   morning 
  the 
  moths 
  found 
  in 
  one 
  such 
  trap 
  were 
  estimated 
  at 
  from 
  

   1,200 
  to 
  1,500. 
  Another 
  trap, 
  placed 
  on 
  a 
  beet 
  dump 
  with 
  an 
  

   electric 
  Hght 
  to 
  attract 
  the 
  moths, 
  is 
  said 
  to 
  have 
  caught 
  as 
  many 
  as 
  

   7,000 
  moths 
  in 
  a 
  single 
  night. 
  According 
  to 
  J. 
  E. 
  Graf 
  most 
  of 
  the 
  

   moths 
  were 
  the 
  common 
  cutworm, 
  Peridroma 
  saucia.

  On 
  the 
  19th 
  May 
  1914, 
  larvae 
  of 
  Anarsia 
  Uneatella 
  were 
  found 
  in 
  

   freshly 
  constructed 
  hibernating 
  cells 
  in 
  the 
  forks 
  of 
  young 
  peach 
  trees. 
  

   Again 
  on 
  23rd 
  June 
  an 
  abundance 
  of 
  very 
  small 
  larvae 
  were 
  found 
  

   in 
  hibemaculae. 
  In 
  this 
  case 
  they 
  were 
  in 
  forks 
  of 
  peach 
  trees 
  which 
  

   were 
  probably 
  five 
  years 
  of 
  age 
  and 
  upon 
  which 
  there 
  was 
  much 
  fruit. 
  

   These 
  observations 
  are 
  beheved 
  to 
  indicate 
  the 
  presence 
  of 
  only 
  one 
  

   strung-out 
  brood 
  of 
  this 
  insect, 
  instead 
  of 
  three, 
  or 
  even 
  four, 
  as 
  has 
  

   been 
  previously 
  reported.
