  A 
  large 
  and 
  very 
  handsome 
  species 
  that 
  is 
  common 
  all 
  along 
  our 
  

   southern 
  coast, 
  and 
  is 
  distributed 
  sparingly 
  throughout

  Save 
  for 
  the 
  slightly 
  larger 
  size 
  and 
  a 
  slightly 
  darker 
  general 
  color, 
  I 
  

   can 
  find 
  no 
  differences 
  between 
  this 
  nymph 
  and 
  that 
  ofT. 
  lacerata 
  

   excepting 
  the 
  ones 
  stated 
  in 
  the 
  table: 
  I 
  find 
  but 
  10 
  lateral 
  setae 
  in 
  my 
  

   nymphs 
  of 
  Carolina, 
  while 
  generally 
  there 
  is 
  an 
  added 
  shorter 
  one 
  

   at 
  the 
  proximal 
  end 
  of 
  the 
  row 
  in 
  lacerata.
