﻿season; 
  and 
  that 
  the 
  midsummer 
  eggs 
  give 
  origin 
  to 
  the 
  larvae 
  which 
  

   pass 
  the 
  winter 
  in 
  the 
  earth. 
  The 
  food 
  plants 
  of 
  the 
  larvae 
  are 
  doubtless 
  

   very 
  imperfectly 
  known. 
  Thus 
  far 
  the 
  larva 
  has 
  been 
  found 
  feeding 
  

   only 
  upon 
  sprouting 
  kernels 
  of 
  corn 
  in 
  the 
  earth 
  and 
  the 
  roots 
  of 
  lamb's- 
  

   quarters 
  {^Chenopodium') 
  and 
  Stramonium 
  (Jamestown 
  weed). 
  The 
  facts 
  

   stated 
  above 
  with 
  regard 
  to 
  the 
  relation 
  of 
  this 
  beetle 
  in 
  the 
  beet 
  field 
  to 
  

   the 
  growth 
  of 
  clover 
  makes 
  it 
  seem 
  likely 
  that 
  the 
  larva 
  may 
  also 
  infest 
  

   that 
  plant. 
  

  

  The 
  larva 
  is 
  a 
  slender, 
  stiff, 
  sluggish 
  insect, 
  about 
  an 
  eighth 
  of 
  an 
  

   inch 
  in 
  length, 
  yellowish 
  white, 
  and 
  narrowing 
  gradually 
  from 
  behind 
  

   forward. 
  The 
  sutures 
  of 
  the 
  thorax 
  form 
  a 
  peculiar 
  X-mark, 
  and 
  the 
  

   anal 
  segment 
  tapers 
  to 
  a 
  prolonged 
  process 
  with 
  a 
  crown 
  of 
  short 
  spines 
  

   and 
  four 
  long 
  spinose 
  hairs 
  at 
  its 
  apex. 
  

  

  " 
  The 
  egg 
  is 
  elliptical 
  but 
  somewhat 
  inconstant 
  in 
  outline, 
  about 
  

   two 
  and 
  a 
  half 
  times 
  as 
  long 
  as 
  wide, 
  and 
  opaque,

  buff

   color. 
  The 
  sculpture 
  of 
  the 
  surface, 
  as 
  observed 
  under 
  a 
  moderately 
  

   high 
  power 
  of 
  microscope, 
  appears 
  to 
  be 
  granulated, 
  but 
  under 
  a 
  higher 
  

   lens 
  it 
  seems 
  to 
  be 
  divided 
  into 
  very 
  minute 
  and 
  rather 
  ill-defined 
  shal- 
  

   low 
  concave 
  hexagonal 
  areas 
  arranged 
  in

  These 
  minute 
  brownish 
  elongate 
  

   flea-beetles, 
  only 
  about 
  a 
  twelfth 
  of 
  an 
  

   inch 
  in 
  length, 
  were 
  found 
  in 
  small 
  

   number 
  on 
  sugar 
  beets 
  in 
  Urbana 
  in 
  

   October. 
  Davis 
  reports 
  it 
  as 
  the 
  com- 
  

   monest 
  of 
  the 
  celery 
  flea-beetles. 
  It 
  

   occurs 
  from 
  the 
  Dakotas 
  and 
  Canada 
  

   south 
  to 
  Kansas, 
  Missouri, 
  and 
  North 
  

   Carolina. 
  It 
  hibernates 
  as 
  an 
  adult, 
  

   and 
  has 
  been 
  taken 
  by 
  us 
  in 
  that 
  stage 
  

   from 
  winter 
  quarters 
  November 
  15th 
  

   and 
  March 
  2d. 
  It 
  has 
  been 
  most 
  

   abundant 
  with 
  us, 
  however, 
  in 
  May, 
  

   June, 
  and 
  July. 
  The 
  immature 
  stages 
  and 
  life 
  history 
  are 
  unknown.

  This 
  minute 
  brown 
  species, 
  slightly 
  shorter 
  than 
  the 
  preceding, 
  was 
  

  

  found 
  on 
  sugar 
  beets 
  in 
  Illinois 
  in 
  July 
  and 
  October, 
  quite 
  abundantly 
  

  

  in 
  the 
  latter 
  month. 
  Its 
  known 
  range 
  includes 
  Georgia,

  and 
  

  

  Texas, 
  Illinois, 
  and 
  Wisconsin. 
  Its 
  life 
  history 
  is
