  but 
  some 
  of 
  the 
  larger 
  withered 
  grapes 
  contained 
  two 
  seeds, 
  

   each 
  having 
  a 
  dark 
  spot 
  upon 
  its 
  surface. 
  On 
  cutting 
  the 
  

   seeas 
  carefully 
  open, 
  the 
  kernel 
  was 
  found 
  almost 
  entirely 
  

   consumed, 
  and 
  the 
  cavity 
  occupied 
  by 
  a 
  small, 
  milk-white, 
  

   footless 
  grub, 
  with 
  a 
  pair 
  of 
  brown 
  hooked 
  mandibles, 
  a 
  

   smooth 
  and 
  glossy 
  skin, 
  with 
  a 
  few 
  very 
  line 
  short 
  white 
  hairs. 
  

   When 
  at 
  rest, 
  it 
  was 
  nearly 
  oval 
  in 
  form, 
  but 
  when 
  in 
  motion, 
  

   its 
  body 
  became 
  elongated, 
  varying 
  in 
  length 
  from 
  one-fifteenth 
  

   to 
  one-twelfth 
  of 
  an 
  inch." 
  

  

  Mr. 
  Saunders 
  found 
  the 
  larvae 
  unchanged 
  within 
  the 
  seeds, 
  

   and 
  quite 
  active, 
  in 
  an 
  examination 
  made 
  in 
  the 
  month 
  of 
  

   February. 
  Early 
  in 
  July 
  they 
  were 
  still 
  soft, 
  but 
  motionless, 
  

   and 
  they 
  may 
  have 
  been 
  in 
  the 
  pupa 
  state. 
  On 
  the 
  9th 
  of 
  

   August, 
  a 
  number 
  of 
  the 
  perfect 
  insects, 
  dead, 
  were 
  found 
  

   when 
  the 
  contents 
  of 
  the 
  bottle 
  containing 
  the 
  seeds 
  were 
  

   turned 
  out 
  upon 
  a 
  piece 
  of 
  white 
  paper. 
  They 
  had 
  probably 
  

   effected 
  their 
  escape 
  during 
  the 
  last 
  half 
  of 
  July. 
  

  

  It 
  is 
  possible 
  that 
  this 
  insect 
  may 
  not 
  prove 
  so 
  destructive 
  

   as 
  it 
  threatens 
  to 
  do, 
  by 
  spreading 
  from 
  garden 
  to 
  garden, 
  and 
  

   throughout 
  our 
  vineyards. 
  If 
  it 
  were 
  left 
  unmolested, 
  under 
  

   circumstances 
  continuing 
  to 
  favor 
  its 
  increase, 
  it 
  is 
  capable 
  

   within 
  a 
  few 
  years 
  of 
  compelling 
  the 
  abandonment 
  of 
  the 
  cul- 
  

   ture 
  of 
  the 
  grape 
  in 
  our 
  country. 
  Hidden 
  within 
  the 
  seeds, 
  it 
  

   could 
  readily 
  be 
  distributed 
  in 
  the 
  transportation 
  of 
  the 
  grapes 
  

   to 
  distant 
  markets, 
  through 
  the 
  several 
  States 
  of 
  the 
  Union. 
  

   This 
  is 
  the 
  first 
  instance 
  that 
  we 
  have 
  heard 
  of 
  its 
  appearance 
  

   within 
  the 
  United 
  States. 
  

  

  Encouraged 
  by 
  the 
  recollection 
  that 
  at 
  different 
  times 
  in 
  the 
  

   past, 
  when 
  a 
  destructive 
  insect 
  pest 
  has 
  threatened 
  to 
  pursue 
  

   its 
  ravages 
  without 
  the 
  probability 
  of 
  its 
  arrest 
  by 
  human 
  

   agency, 
  some 
  kindly 
  parasite 
  or 
  climatic 
  condition 
  has 
  come 
  

   to 
  our 
  aid 
  — 
  so 
  we 
  shall 
  hope 
  that 
  in 
  the 
  present 
  instance 
  the 
  

   little 
  Isosoma 
  vitis 
  will 
  not 
  find 
  conditions 
  more 
  favorable 
  to 
  

   its 
  existence 
  in 
  its 
  new 
  habitat, 
  or 
  others 
  that 
  it 
  may 
  select, 
  

   than 
  it 
  enjoyed 
  in 
  Canada, 
  where 
  its 
  spread 
  seems 
  to 
  have 
  

   been, 
  for 
  the 
  time, 
  at 
  least, 
  arrested. 
  

  

  ]STo 
  means, 
  however, 
  should 
  be 
  left 
  untried 
  that 
  promise 
  to 
  

   arrest 
  and 
  destroy 
  it. 
  Knowing 
  the 
  history 
  of 
  the 
  insect, 
  we 
  

   are 
  able 
  to 
  state 
  that 
  it 
  can 
  best, 
  perhaps 
  only, 
  be 
  destroyed 
  

   while 
  in 
  the 
  larval 
  or 
  grub 
  state, 
  or 
  previous 
  to 
  attaining 
  its 
  

   perfect 
  condition. 
  This 
  may 
  be 
  done 
  by 
  burning 
  all 
  the 
  

   shriveled 
  grapes, 
  as 
  well 
  as 
  those 
  not 
  shriveled, 
  but 
  showing
