  fabricii

  of

  uniform 
  dull-ash 
  color. 
  It 
  is 
  

   found 
  usually 
  east

  the 
  Mississippi, 
  but 
  also

  Remedies. 
  — 
  Hand-picking 
  and 
  brushing 
  the 
  insects 
  off 
  the 
  leaves 
  in 
  

   the 
  morning 
  and 
  evening 
  is 
  the 
  best 
  remedy. 
  Harris 
  says: 
  "I 
  have 
  

   repeatedly 
  taken 
  these 
  insects 
  in 
  considerable 
  quantities, 
  by 
  brushing 
  

   or 
  shaking 
  them 
  from 
  the 
  potato- 
  vines 
  into 
  a 
  broad 
  tin 
  pan, 
  from 
  which 
  

   they 
  were 
  emptied 
  into 
  a 
  covered 
  pail 
  containing 
  a 
  little 
  water, 
  which, 
  

   by 
  wetting 
  their 
  wings, 
  prevented 
  their 
  flying 
  out 
  when 
  the 
  pail 
  was 
  un- 
  

   covered. 
  The 
  same 
  method 
  may 
  be 
  employed 
  for 
  taking 
  the 
  other 
  kinds 
  

   of 
  cantharides 
  when 
  they 
  become 
  troublesome 
  and 
  destructive 
  from 
  

   their 
  numbers; 
  or 
  they 
  may 
  be 
  caught 
  by 
  gently 
  sweeping 
  the 
  plants 
  

   they 
  frequent 
  with 
  a 
  deep 
  muslin 
  bag-net. 
  They 
  should 
  be 
  killed 
  by 
  

   throwing 
  them 
  into 
  scalding-water 
  for 
  one 
  or 
  two 
  minutes, 
  after 
  which 
  

   they 
  may 
  ])e 
  spread 
  out 
  on 
  sheets 
  of 
  paper 
  to 
  dry, 
  and 
  may 
  be 
  made 
  

   profitable 
  by 
  selling 
  them 
  to 
  the 
  apothecaries 
  for 
  medical 
  use."

   Feeding 
  on

  and 
  liable 
  to 
  devonr 
  potatoes 
  ; 
  a 
  light-gray 
  blister-beetle, 
  spotted 
  with 
  

   black 
  ; 
  destructive 
  about 
  Manitouj 
  Colo. 
  

  

  While 
  none 
  of 
  the 
  preceding 
  species 
  have 
  yet 
  been 
  found 
  to 
  be 
  injuri- 
  

   ous 
  in 
  Colorado 
  or 
  adjacent 
  Territories, 
  there 
  are 
  a 
  number 
  of 
  species 
  of 
  

   blister-beetles 
  which 
  inhabit 
  the 
  Eocky 
  Mountain 
  Plateau, 
  and 
  two 
  have 
  

   beeu 
  found 
  to 
  be 
  injurious 
  to 
  field-crops. 
  While 
  at 
  Manitou 
  duiing 
  the 
  

   middle 
  of 
  July 
  I 
  visited 
  a 
  large 
  farm 
  and 
  found 
  this 
  spotted 
  blister- 
  

   beetle 
  in 
  abundance 
  on 
  the 
  leaves 
  of 
  the 
  beet, 
  and 
  was 
  told 
  that 
  on 
  the 
  

   1st 
  of 
  July 
  they 
  swarmed 
  upon 
  the 
  leaves 
  so 
  that 
  " 
  the 
  plants 
  were 
  

   gray 
  with 
  them." 
  I 
  also 
  found 
  this 
  beetle 
  at 
  Golden, 
  and 
  it 
  is 
  evident 
  

   tnat 
  it 
  is 
  destined 
  to 
  be 
  more 
  or 
  less 
  annoying 
  to 
  garden-vegetables 
  and 
  

   probably 
  potatoes. 
  

  

  Desciipfion 
  of 
  the 
  'beetle. 
  — 
  Pale 
  yellowish-gray 
  varying 
  to 
  a 
  dark 
  gray, 
  being 
  dark, 
  

   covered 
  with 
  a 
  gray 
  powder, 
  consisting 
  of 
  minute 
  short 
  hairs 
  when 
  examined 
  under 
  a 
  

   hand-lens, 
  and 
  finely 
  spotted 
  with 
  black 
  on 
  the 
  wing-covers, 
  the 
  spots 
  being 
  nearly 
  

   obsolete 
  on 
  the 
  head 
  and 
  prothoras 
  as 
  well 
  as 
  the 
  under 
  side 
  of 
  the 
  body. 
  The 
  legs 
  

   are 
  of 
  the 
  same 
  color 
  as 
  the 
  rest 
  of 
  the 
  body, 
  but 
  the 
  toe-joints 
  (tarsi) 
  and 
  the 
  tips 
  of 
  

   the 
  shanks 
  (tibiae) 
  are 
  blackish, 
  as 
  well 
  as 
  the 
  antennsB 
  and 
  feelers 
  (palpi). 
  It 
  is 
  usually 
  

   about 
  half 
  an 
  inch 
  long, 
  but 
  varies 
  from 
  a 
  quarter 
  to 
  half 
  au 
  inch. 
  It 
  is 
  rather 
  slenderer 
  

   in 
  form 
  than 
  any 
  other 
  of 
  the 
  species 
  here 
  named 
  except 
  the 
  striped 
  species 
  {E. 
  vittata). 
  

   It 
  also 
  occurs 
  in 
  Kansas 
  and 
  Eastern 
  New 
  Mexico. 
  This 
  species 
  has 
  been 
  named 
  by 
  

   Dr. 
  Horn.

  (Plate

  — 
  

   Injuring 
  the 
  potato-leaves 
  in 
  Southern 
  Colorado, 
  and 
  doing 
  more 
  damage 
  locally 
  than 
  

   the

  Colorado 
  potato-beetle 
  ; 
  a 
  beautiful 
  gray-spotted 
  shiniqg-black 
  blister- 
  

   beetle. 
  

  

  I 
  received 
  from 
  Mr. 
  T. 
  Martin 
  Trippe, 
  a. 
  well-known 
  naturalist, 
  numerous 
  

   specimens 
  of 
  this 
  blister-beetle, 
  with 
  the 
  following 
  account, 
  dated 
  How- 
  

   ardsville, 
  Colo., 
  July 
  25, 
  1875 
  : 
  

  

  I 
  send 
  you 
  herewith 
  some 
  specimens 
  of 
  a 
  beetle 
  that 
  has 
  lately 
  destroyed 
  the 
  jiotato- 
  

   plant 
  in 
  this 
  vicinity. 
  Thoy 
  are 
  worse 
  than 
  the 
  Doriipliora 
  decemlineata 
  in 
  the 
  

   extent 
  and 
  rapidity 
  of 
  their 
  devastations, 
  and 
  seem 
  to 
  have 
  driven 
  the 
  latter 
  out 
  of 
  

   the 
  country. 
  Before 
  the 
  appearance 
  of 
  this 
  new 
  potato-bug 
  the 
  latter 
  were 
  quite 
  uu- 
  

   merous, 
  and 
  had 
  already 
  begun 
  to 
  injure 
  the 
  crops 
  somewhat; 
  but 
  these 
  new-comers 
  

   stripped 
  the 
  vines 
  in 
  s^ 
  week, 
  and 
  a 
  few 
  days 
  after 
  they 
  appeared 
  in 
  numbers 
  the 
  

   Doryphoras 
  were 
  nowhere 
  to 
  be 
  seen. 
  No 
  one 
  seems 
  to 
  know 
  of 
  or 
  to 
  have 
  seen 
  them 
  

   before. 
  Before 
  immersion 
  in 
  alcohol 
  they 
  were 
  spotted 
  with 
  white, 
  the 
  spots 
  being 
  

   quite 
  small 
  — 
  size 
  of 
  a 
  pin-poiut 
  ; 
  the 
  head 
  unspotted. 
  They 
  feed 
  on 
  wild 
  Solanacece.
