  have

   it

  to

  the

  It 
  is 
  not 
  improbable 
  that 
  this 
  insect 
  in 
  its 
  early 
  stage 
  as 
  a 
  larva 
  is 
  

   beneficial 
  to 
  vegetation, 
  since 
  so 
  far 
  as 
  known 
  the 
  young 
  of 
  our 
  fire-flies 
  

   devour 
  worms, 
  other 
  larva, 
  and 
  snails, 
  but 
  the 
  individuals 
  of 
  this 
  species 
  

   are 
  so 
  rare, 
  that 
  they 
  probably 
  exert 
  but 
  a 
  slight 
  influence 
  for 
  good 
  or 
  evil, 
  

   agriculturally 
  speaking. 
  I 
  have 
  received 
  three 
  specimens 
  of 
  this 
  larva 
  

   from 
  Texas 
  through 
  Mr. 
  G. 
  W. 
  Belfrage, 
  on 
  whose 
  authority 
  solely 
  the 
  

   above 
  determination 
  is 
  given. 
  For 
  a 
  specimen 
  of 
  the 
  male, 
  and 
  of 
  the 
  

   exceedingly 
  rare 
  female, 
  I 
  am 
  indebted 
  to 
  the 
  kindness 
  of 
  G. 
  D. 
  Smith, 
  

   esq., 
  of 
  Boston, 
  who 
  loaned 
  them 
  for 
  the 
  purpose 
  of 
  being 
  drawn. 
  

  

  The 
  larva 
  is 
  unsually 
  long 
  and 
  narrow, 
  and 
  much 
  flattened.
