  Remarks. 
  — 
  One 
  female 
  from 
  Crystal 
  River, 
  Citrus 
  County, 
  Fla., 
  

   Sept. 
  18, 
  1950, 
  Hudson, 
  is 
  provisionally 
  referred 
  to 
  S. 
  (S.) 
  thomsenae, 
  

   since 
  it 
  resembles 
  the 
  male 
  in 
  coloration, 
  although 
  it 
  may 
  prove 
  to 
  be 
  

   a 
  dark 
  specimen 
  of 
  S. 
  (S.) 
  bulla. 
  This 
  species 
  is 
  named 
  in 
  honor 
  of 
  

   Dr. 
  Lillian 
  Thomsen, 
  who 
  has 
  contributed 
  much 
  to 
  the 
  study 
  of 
  

   North 
  American 
  Heleidae.
