  Remarks. 
  — 
  Closely 
  allied 
  to 
  S. 
  paulistensis 
  Lane, 
  1947, 
  from 
  Brazil 
  

   which 
  differs, 
  however, 
  in 
  having 
  the 
  legs 
  yellowish 
  rather 
  than 
  black- 
  

   ened, 
  in 
  lacking 
  the 
  dark 
  spot 
  at 
  apex 
  of 
  second 
  radial 
  cell, 
  and 
  in 
  

   having 
  the 
  lateral 
  sclerites 
  of 
  the 
  male 
  aedeagus 
  shorter, 
  with 
  apices 
  

   capitate 
  and 
  bent 
  mesad 
  rather 
  than 
  slender 
  and 
  bent 
  laterad. 
  S. 
  

   rabelloi 
  Lane, 
  1947, 
  is 
  also 
  closely 
  related, 
  but 
  is 
  a 
  larger, 
  hairier 
  

   species 
  with 
  three 
  dark 
  wing 
  spots, 
  including 
  one 
  at 
  apex 
  of 
  first 
  

   radial 
  cell, 
  and 
  has 
  several 
  pairs 
  of 
  batonnets 
  on 
  fifth 
  tarsal 
  segment. 
  

   I 
  am 
  happy 
  to 
  name 
  this 
  species 
  for 
  Mrs. 
  Elisabeth 
  C. 
  Beck 
  of 
  Arling- 
  

   ton, 
  Fla., 
  who 
  has 
  kindly 
  sent 
  me 
  so 
  many 
  interesting 
  Florida 
  heleids.
