  by 
  the 
  presence 
  of 
  the 
  moth 
  at 
  electric 
  lights 
  and 
  at 
  ''sugar." 
  Its 
  larval 
  

   habits 
  in 
  this 
  country 
  are 
  entirely 
  unknown, 
  and, 
  indeed, 
  the 
  larva 
  itself 
  

   has 
  not 
  been 
  recognized 
  by 
  us. 
  It 
  is 
  worthy 
  of 
  mention 
  here, 
  however, 
  

   because 
  of 
  its 
  injuries 
  to 
  beets 
  in 
  the 
  Old 
  World, 
  where 
  it 
  is 
  reported 
  

   by 
  Kaltenbach 
  to 
  feed 
  on 
  garden 
  vegetables, 
  including 
  celery, 
  beets, 
  

   chicory, 
  endive, 
  and 
  lettuce. 
  The 
  moth 
  is 
  a 
  trim 
  little 
  species, 
  slightly 
  

   more 
  than 
  an 
  inch 
  across 
  the 
  wings, 
  resembling 
  a 
  dwarfed 
  c-nignmi 
  

   except 
  for 
  a 
  well-marked 
  light 
  streak 
  along 
  the 
  anterior 
  border 
  of 
  the 
  

   fore 
  wings. 
  In 
  this 
  country 
  the 
  insect 
  seems 
  to 
  be 
  two-brooded, 
  like 
  

   c-nign/tn, 
  the 
  moths 
  being 
  found 
  in 
  Illinois 
  in 
  the 
  latter 
  part 
  of 
  May 
  and 
  

   in 
  June, 
  and 
  again 
  in 
  August.

  No 
  leaf-rollers 
  have 
  hitherto 
  been 
  reported 
  as 
  injurious 
  to 
  the 
  beet, 
  

   but 
  during 
  the 
  past 
  summer 
  we 
  twice 
  collected 
  from 
  beet 
  leaves 
  a 
  very 
  

   common 
  greenhouse 
  

  

  pest 
  belonging 
  to 
  one 
  

   of 
  the 
  leaf-roller 
  fam- 
  

   ilies 
  [Fyraustidce) 
  and 
  

   bred 
  these 
  larvae 
  to 
  

   the 
  imago 
  of 
  the 
  

   above 
  species. 
  These 
  

   insects 
  were 
  obtained 
  

   from 
  beet 
  fields 
  near 
  

   Pekin, 
  111., 
  and 
  at 
  

   Urbana.

  three-eighths

  long, 
  were 
  also 
  occasionally 
  seen 
  in

  The

  is 
  translucent 
  green,

  lines 
  on 
  the 
  body 
  

   and 
  two 
  black 
  dots 
  on 
  the 
  neck 
  shield. 
  It 
  feeds 
  in 
  a 
  loose 
  marginal 
  

   fold 
  of 
  the 
  leaf, 
  fastened 
  down 
  by 
  a 
  web 
  spun 
  by 
  itself; 
  or 
  sometimes 
  

   it 
  draws 
  two 
  leaves 
  together, 
  forming 
  a 
  loosely 
  webbed 
  retreat 
  between 
  

   them. 
  It 
  is 
  said 
  to 
  live, 
  when 
  full 
  grown, 
  in 
  a 
  webbed 
  concavity 
  on 
  the 
  

   under 
  side 
  of 
  the 
  leaf, 
  but 
  according 
  to 
  our 
  observation 
  this 
  is 
  certainly 
  

   not 
  always 
  true.
