  Liburnia 
  puella 
  Van 
  D. 
  

   (PI. 
  I., 
  Fig. 
  2.) 
  

   This 
  species 
  is 
  recorded 
  from 
  Iowa, 
  Mississippi, 
  New 
  York, 
  and 
  

   New 
  Jersey, 
  and 
  seems 
  to 
  have 
  a 
  more 
  southerly 
  range 
  than 
  L. 
  ornata. 
  

   We 
  have 
  taken 
  it 
  repeatedly 
  on 
  sugar 
  beets 
  on 
  the 
  University 
  farm 
  in 
  

   July 
  and 
  October. 
  In 
  our 
  general 
  collections 
  it 
  is 
  recorded 
  for 
  central 
  

   Illinois 
  from 
  grass, 
  grains, 
  and 
  various 
  low 
  plants 
  in 
  July 
  and 
  again 
  in 
  

   the 
  fall 
  up 
  to 
  about 
  the 
  middle 
  of 
  November; 
  also, 
  in 
  August, 
  for 
  ex- 
  

   treme 
  southern 
  Illinois. 
  It 
  is 
  thus 
  probably 
  two-brooded, 
  hibernating 
  

   as 
  an 
  adult.

  This 
  seems 
  to 
  be 
  a 
  northerly 
  species, 
  ranging 
  from 
  Canada 
  and 
  

   New 
  York 
  to 
  Colorado, 
  Arkansas, 
  and 
  Kentucky. 
  It 
  is 
  moderately 
  

   common 
  in 
  Illinois, 
  but 
  did 
  not 
  appear 
  in 
  our 
  last 
  summer's 
  collections 
  

   from 
  the 
  sugar 
  beet. 
  It 
  has 
  been 
  found 
  on 
  beets 
  in 
  Iowa, 
  however, 
  by 
  

   Professor 
  Herbert 
  Osborn, 
  whose 
  studies 
  have 
  contributed 
  much 
  to 
  our 
  

   knowledge 
  of 
  the 
  leaf-hoppers 
  of 
  this 
  genus. 
  The 
  species 
  under 
  con- 
  

   sideration 
  he 
  says 
  is 
  "single 
  brooded, 
  the 
  adult 
  appearing 
  in 
  early 
  

   spring, 
  the 
  females 
  remaining 
  until 
  into 
  July. 
  The 
  eggs 
  are 
  probably 
  

   all 
  deposited 
  by 
  the 
  middle 
  of 
  June, 
  from 
  which 
  the 
  larvae 
  appear 
  in 
  

   July, 
  and 
  by 
  fall 
  are 
  nearly 
  or 
  quite 
  full 
  grown, 
  passing 
  the 
  winter 
  and 
  

   issuing 
  as 
  adults 
  again 
  early 
  the 
  next 
  spring." 
  This 
  species 
  has 
  been 
  

   found 
  on 
  a 
  great 
  variety 
  of 
  plants, 
  mostly 
  Compositce, 
  such 
  as 
  sunflower 
  

   and 
  boneset 
  (»llupatoriiim), 
  Cntci/era;, 
  Chenopodiacea 
  and 
  their 
  garden 
  

   relatives, 
  beets, 
  horseradish, 
  cabbage, 
  spinach, 
  etc. 
  "The 
  larvae 
  re- 
  

   main 
  on 
  or 
  near 
  the 
  ground 
  and 
  conceal 
  themselves 
  in 
  the 
  rubbish 
  and 
  

   humus, 
  for 
  which 
  their 
  color 
  and 
  appearance 
  is 
  peculiarly 
  adapted." 
  

   They 
  usually 
  occur 
  in 
  woods 
  and 
  similar 
  shaded 
  situations, 
  but 
  also 
  on
