  History 
  of 
  Durham. 
  

  

  the 
  antenn£e 
  and 
  the 
  feet. 
  The 
  thorax 
  is 
  thickly 
  punctured, 
  

   and 
  the 
  wing 
  covers 
  conspicuously 
  striated 
  and 
  punctured 
  

   between 
  the 
  striae. 
  The 
  Epitrix 
  pubescenes 
  is 
  slightly 
  more 
  

   oblong, 
  and 
  not 
  quite 
  so 
  convexed 
  as 
  the 
  former, 
  but 
  other- 
  

   wise 
  is 
  about 
  the 
  same 
  size. 
  1'he 
  whole 
  of 
  the 
  body 
  beneath 
  

   is 
  of 
  a 
  dull-black 
  color, 
  including 
  also 
  the 
  posterior 
  thighs. 
  

   The 
  feet, 
  the 
  antennse 
  (which 
  are 
  slightly 
  serrated 
  along 
  the 
  

   anterior 
  margin), 
  and 
  the 
  whole 
  of 
  the 
  dorsal 
  or 
  upper 
  part 
  

   of 
  the 
  body, 
  are 
  of 
  a 
  honey-yellow 
  color, 
  except 
  about 
  a 
  

   third 
  of 
  the 
  middle 
  portion 
  of 
  the 
  wing 
  covers, 
  which 
  is 
  a 
  

   dusky 
  black. 
  The 
  thorax 
  is 
  of 
  a 
  much 
  brighter 
  color 
  than 
  

   the 
  other 
  upper 
  portions 
  of 
  the 
  body, 
  and 
  the 
  eyes 
  are 
  very 
  

   black, 
  their 
  composite 
  character 
  being 
  more 
  distinct 
  than 
  

   in 
  the 
  first-named 
  species 
  ; 
  and 
  except 
  the 
  thorax, 
  the 
  upper 
  

   and 
  lower 
  part 
  of 
  the 
  whole 
  body 
  is 
  pubescent. 
  This 
  pu- 
  

   bescence 
  is 
  conspicuous 
  in 
  rows 
  between 
  the 
  striae 
  of 
  the 
  wing 
  

   covers 
  and 
  along 
  the 
  margins 
  of 
  the 
  abdominal 
  segments. 
  

   This 
  species 
  is 
  the 
  most 
  troublesome 
  to 
  the 
  young 
  cotton 
  

   and 
  cabbage 
  plants 
  of 
  the 
  middle 
  Southern 
  States. 
  They 
  

   also 
  attack 
  the 
  seed-leaves 
  of 
  beans 
  and 
  other 
  leguminous 
  

   plants, 
  but 
  appear 
  to 
  have 
  an 
  especial 
  fondness 
  for 
  tobacco. 
  

   These 
  insects 
  are 
  about 
  one- 
  sixteenth 
  to 
  one 
  tenth 
  of 
  an 
  inch 
  

   in 
  length. 
  

  

  The 
  above-named 
  and 
  other 
  species 
  of 
  the 
  Halticans 
  feed 
  

   on 
  a 
  variety 
  of 
  plants. 
  The 
  sweet 
  potato, 
  cabbage, 
  beet, 
  

   turnip, 
  radish, 
  horseradish, 
  common 
  nettle, 
  and 
  the 
  James- 
  

   town 
  weed 
  are 
  all 
  infested 
  by 
  one 
  or 
  the 
  other 
  and 
  often 
  by 
  

   the 
  same 
  species 
  of 
  this 
  omnivorous 
  family. 
  When 
  dis- 
  

   turbed, 
  the 
  fiea-beetles 
  leap 
  off 
  the 
  plants 
  and 
  hide 
  them- 
  

   selves 
  quickly 
  in 
  the 
  dry 
  soil 
  or 
  under 
  small 
  clods. 
  Various 
  

   solutions, 
  poisonous 
  or 
  simply 
  distasteful 
  to 
  these 
  insects, 
  

   have 
  been 
  used 
  with 
  successful 
  results. 
  Ashes, 
  slaked 
  lime, 
  

   and 
  soot, 
  dusted 
  upon 
  melon, 
  cucumber, 
  potato, 
  and 
  turnip 
  

   plants, 
  and 
  applied 
  in 
  the 
  morning, 
  when 
  the 
  dew 
  is 
  on 
  the 
  

   plants 
  and 
  while 
  the 
  beetles 
  are 
  sluggish, 
  are 
  effectual 
  in 
  

   most 
  instances. 
  Of 
  various 
  plans 
  to 
  keep 
  them 
  from 
  tobac- 
  

   co-beds 
  probably 
  the 
  only 
  certain 
  protection 
  is 
  to 
  cover 
  the 
  

   seed-bed 
  with 
  cfoth, 
  as 
  suggested 
  heretofore. 
  

  

  Transplanted 
  into 
  the 
  field, 
  the 
  tobacco 
  plant 
  is 
  exposed 
  

   to 
  the 
  attacks 
  of 
  other 
  insects. 
  The 
  greasy 
  cut-worm 
  usually 
  

   cuts 
  off 
  the 
  plant 
  just 
  beneath 
  the 
  surface 
  of 
  the 
  soil 
  without 
  

   cutting 
  the 
  top 
  at 
  all. 
  When 
  these 
  worms 
  are 
  disturbed, 
  

   they 
  immediately 
  coil 
  themselves 
  into 
  a 
  ring. 
  They 
  do 
  not
