   This 
  minute, 
  active, 
  black 
  hopper 
  is 
  common 
  in 
  the 
  beet 
  field, 
  but 
  

   much 
  less 
  so 
  than 
  the 
  following 
  species, 
  with 
  which, 
  indeed, 
  it 
  is 
  likely 
  

   to 
  be 
  confused 
  unless 
  closely 
  examined. 
  It 
  is 
  narrower 
  and 
  a 
  little 
  

   longer 
  than 
  the 
  other, 
  and 
  may 
  be 
  further 
  distinguished 
  by 
  the 
  absence 
  

   of 
  the 
  dull 
  white 
  point 
  on 
  the 
  wing. 
  The 
  adults 
  of 
  this 
  insect 
  were 
  

   commonest 
  in 
  our 
  beet 
  fields 
  in 
  July, 
  the 
  earliest 
  fully 
  developed 
  speci- 
  

   mens 
  being 
  noticed 
  June 
  25th. 
  From 
  July 
  onward 
  the 
  number 
  gradu- 
  

   ally 
  diminished 
  until 
  October 
  3d, 
  when 
  the 
  last 
  of 
  the 
  species 
  were 
  seen. 
  

   In 
  Colorado 
  full 
  grown 
  specimens 
  have 
  been 
  taken 
  from 
  May 
  14th 
  to 
  

   August 
  24th, 
  mostly 
  in 
  late 
  July 
  and 
  early 
  August. 
  It 
  occurs 
  through- 
  

   out 
  Illinois 
  and 
  is 
  reported 
  from 
  New 
  York, 
  Colorado, 
  and 
  Utah.*

  This 
  important 
  injurious 
  insect 
  has 
  been 
  treated 
  at 
  some 
  length 
  by 
  

   Chittenden, 
  f 
  and 
  we 
  have 
  but 
  little 
  to 
  add 
  to 
  his 
  account 
  except 
  to 
  

   record 
  it 
  as 
  a 
  common 
  beet 
  insect 
  in 
  Illinois 
  in 
  company 
  with 
  the 
  "false 
  

   flea-hopper" 
  above 
  mentioned. 
  It 
  has 
  occurred 
  especially 
  in 
  our 
  col- 
  

   lections 
  on 
  clover, 
  pigweed 
  {Amarmitus^, 
  and 
  beets. 
  It 
  is 
  injurious, 
  

   according 
  to 
  Chittenden, 
  to 
  beans, 
  peas, 
  egg-plants, 
  chrysanthemums, 
  

   and 
  a 
  large 
  number 
  of 
  common 
  weeds. 
  The 
  visible 
  result 
  of 
  its 
  work 
  

   is 
  a 
  deadening 
  and 
  whitening 
  of 
  the 
  leaf 
  where 
  the 
  beak 
  is 
  inserted 
  to 
  

   pump 
  out 
  the 
  sap, 
  the 
  leaf 
  becoming 
  finely 
  mottled 
  with 
  white 
  whenever 
  

   the 
  injury 
  is 
  considerable. 
  

  

  It 
  is 
  a 
  tiny 
  insect, 
  about 
  a 
  sixteenth 
  of 
  an 
  inch 
  long, 
  shining 
  black 
  

   sprinkled 
  with 
  minute 
  tufts 
  of 
  short 
  yellow 
  hair 
  which 
  may 
  be 
  easily 
  

   rubbed 
  off. 
  The 
  cuneus 
  of 
  the 
  wing 
  is 
  minutely 
  tipped 
  with 
  dull 
  white 
  

   in 
  the 
  long-winged 
  form. 
  In 
  the 
  short-winged 
  form 
  the 
  wings 
  are 
  uni- 
  

   form 
  black 
  and 
  destitute 
  of 
  the 
  membrane, 
  and 
  do 
  not 
  cover 
  the 
  tip 
  

   of 
  the 
  body. 
  The 
  species 
  can 
  be 
  most 
  readily 
  distinguished 
  from 
  

   Agalliasies 
  associatus 
  by 
  the 
  shorter, 
  broader 
  body, 
  which 
  has 
  an 
  oval 
  

   outline, 
  that 
  of 
  the 
  other 
  species 
  being 
  relatively 
  slender, 
  with 
  parallel 
  

   sides. 
  The 
  adults 
  appear 
  rather 
  early 
  as 
  a 
  rule, 
  occurring 
  in 
  the 
  beet 
  

  

  *Popenoe 
  has 
  reported 
  what 
  is 
  probably 
  this 
  species 
  as 
  associated 
  with 
  the 
  garden 
  flea-hopper 
  in 
  

   Kansas. 
  He 
  reports 
  his 
  specimens, 
  on 
  Uhler's 
  authority, 
  a 
  sAgalliastes 
  .bractaius 
  Say; 
  but 
  as 
  Say's 
  

   Cafisus 
  bractatiis 
  is 
  a 
  Halticus 
  close 
  to 
  uhleri, 
  this 
  is 
  probably 
  a 
  slip 
  of 
  the 
  pen.
