  Description 
  of 
  the 
  Beetle.. 
  — 
  It 
  differs 
  from 
  E. 
  maculata 
  in 
  being 
  shining 
  black, 
  with 
  

   pale-gray 
  scalloped 
  lines 
  across 
  the 
  elytra, 
  which 
  unite 
  to 
  form 
  about 
  seven 
  or 
  eight 
  

   pale-gray 
  irregular 
  ringlets, 
  inclosing 
  black 
  spots, 
  whence 
  the 
  name 
  parcUlis, 
  or 
  leop- 
  

   ard-like. 
  The 
  thorax 
  is 
  black, 
  but 
  gray 
  around 
  the 
  edges, 
  and 
  spotted 
  with 
  gray 
  on 
  the 
  

   sides 
  and 
  beneath. 
  It 
  is 
  of 
  the 
  usual 
  form, 
  but 
  a 
  little 
  shorter 
  and 
  stouter'than 
  E. 
  

   maculata. 
  Length,

  The 
  Flea-Beetle, 
  Haltica 
  {Epitrix) 
  cucumeris 
  Harris. 
  (Plate 
  LXVI, 
  Fig. 
  IS,)— 
  

   Eating 
  holes 
  in 
  the 
  leaves, 
  sometimes 
  riddling 
  them, 
  aud 
  causiug 
  them 
  to 
  turn 
  rust- 
  

   color 
  ; 
  minute 
  black 
  beetles, 
  which 
  on 
  being 
  disturbed 
  leap 
  off 
  like 
  fleas. 
  

  

  This 
  minute 
  beetle 
  not 
  only 
  infects 
  the 
  potato 
  but 
  also 
  injures 
  

   beans, 
  beets, 
  tomato-plants, 
  and 
  especially 
  young 
  cucumber-vines. 
  At- 
  

   tacking 
  the 
  leaves 
  when 
  small, 
  andeating 
  round 
  holes 
  in 
  them, 
  by 
  their 
  

   numbers 
  and 
  the 
  pertinacity 
  of 
  their 
  attacks 
  they 
  each 
  year 
  do 
  much 
  

   harm, 
  and 
  certain 
  seasons 
  carry 
  off' 
  whole 
  beds*^ 
  of 
  young 
  beets 
  and 
  

   cucumber-vines, 
  as 
  well 
  as 
  seriously 
  iuj 
  ure 
  the 
  potato-plants. 
  The 
  habit* 
  

   of 
  the 
  young 
  of 
  this 
  species 
  are 
  not 
  known, 
  but 
  it 
  is 
  very 
  probable 
  that 
  

   the 
  eggs 
  are 
  laid 
  on 
  the 
  leaves, 
  and 
  that 
  the 
  larvte 
  bore 
  into 
  and 
  mine 
  

   the 
  leaves 
  feeding 
  upon 
  the 
  pulpy 
  substance. 
  The 
  larvae 
  of 
  other 
  species 
  

   of 
  the 
  genus 
  known 
  to 
  have 
  such 
  habits 
  are, 
  according 
  to 
  Harris, 
  "little 
  

   slender 
  grubs, 
  tapering 
  toward 
  each 
  end, 
  and 
  provided 
  with 
  six 
  legs. 
  

   They 
  arrive 
  at 
  maturity, 
  turn 
  to 
  pupte, 
  and 
  then 
  to 
  beetles 
  in 
  a 
  few 
  i 
  

   weeks. 
  Hence 
  there 
  is 
  a 
  constant 
  succession 
  of 
  these 
  insects 
  in 
  their 
  * 
  

   various 
  states 
  throughout 
  the 
  summer." 
  

  

  Description.— 
  It 
  is 
  only 
  one-sixteenth 
  of 
  an 
  inch 
  long, 
  of 
  a 
  black 
  color, 
  with 
  clay- 
  yel- 
  

   low 
  autenuEe 
  and 
  legs, 
  except 
  the 
  hindmost 
  thighs, 
  which 
  are 
  brown. 
  The 
  upper 
  side 
  

   of 
  the 
  body 
  is 
  covered 
  with 
  punctures, 
  which 
  are 
  arranged 
  iu 
  rows 
  on 
  the 
  wing-cases; 
  

   aud 
  there 
  is 
  a 
  deep 
  transverse 
  furrow 
  across 
  the 
  hinder 
  part 
  of 
  the 
  thorax.

  them 
  to

  bug. 
  

  

  This 
  bug 
  is 
  very 
  widely 
  disseminated, 
  and 
  is 
  everywhere 
  abundant 
  and 
  

   annoying 
  in 
  the 
  United 
  States 
  from 
  Maine 
  southward 
  to 
  Alabama, 
  and 
  

   westward 
  to 
  Colorado 
  and 
  Wyoming. 
  Uhler 
  states 
  that 
  specimens 
  were 
  

   collected 
  above 
  the 
  timber-line 
  in 
  Colorado 
  by 
  Lieutenant 
  Carpenter 
  ; 
  j 
  

   and 
  it 
  occurs 
  on 
  the 
  bald 
  summits 
  of 
  the 
  highest 
  mountains 
  in 
  North 
  

   Carolina. 
  It 
  hibernates, 
  and 
  iu 
  New 
  England 
  appears 
  in 
  April.
