  to 
  the 
  U. 
  S. 
  National 
  Museum. 
  I 
  inquired 
  especially 
  as 
  to 
  the 
  apparent 
  

   permanence 
  of 
  the 
  infestation, 
  and 
  on 
  June 
  24, 
  1952, 
  a 
  colleague 
  of 
  Mr. 
  

   Gross', 
  W. 
  B. 
  Gresham, 
  Jr., 
  replied, 
  "It 
  seems 
  evident 
  to 
  us 
  that 
  

   Nauphoeta 
  is 
  in 
  Florida 
  to 
  stay. 
  They 
  appear 
  to 
  be 
  well 
  adapted 
  and 
  

   quite 
  numerous 
  in 
  the 
  locations 
  where 
  we 
  have 
  noted 
  them. 
  All 
  in- 
  

   festations 
  noted 
  have 
  been 
  within 
  commercial 
  buildings 
  engaged 
  in 
  the 
  

   manufacture 
  of 
  animal 
  feeds. 
  I 
  myself 
  have 
  not 
  noted 
  any 
  out 
  of 
  

   doors." 
  Notes 
  on 
  the 
  Florida 
  infestations 
  by 
  Ratcliffe 
  (1952) 
  and 
  

   Gresham 
  (1952) 
  have 
  appeared.
