   Empeda 
  nigrolineata 
  Enderlein,

  The 
  species 
  is 
  allied 
  to 
  E. 
  stigmatica 
  Osten 
  Sacken, 
  especially 
  in 
  the 
  

   variety 
  puhescens. 
  This 
  race 
  differs 
  in 
  having 
  the 
  pubescence 
  of 
  the 
  

   wing, 
  lack 
  of 
  the 
  stigmal 
  spot, 
  and 
  in 
  color. 
  Typical 
  nigrolineata 
  can 
  

   not 
  be 
  mistaken 
  for 
  stigmatica 
  by 
  its 
  very 
  striking 
  coloration. 
  

  

  A 
  redescription 
  of 
  typical 
  nigrolineata, 
  based 
  on 
  forty 
  specimens, 
  is 
  

   as 
  follows: 
  

  

  Male. 
  —

  3-3.3 
  mm.; 
  wing, 
  4.8-5 
  mm.

  Length, 
  3.9-5 
  mm.; 
  wing, 
  5.1-6 
  mm.

  Tuber- 
  

   culate

  I 
  have

  a 
  series 
  of 
  49 
  specimens 
  from 
  the 
  United 
  States 
  

   National 
  Museum 
  collection. 
  These

  collected 
  by 
  G.

  Guatemala, 
  Central 
  America, 
  July, 
  1902. 
  Forty 
  of 
  

   these 
  are 
  referable 
  to 
  typical 
  nigrolineata; 
  nine 
  are 
  referable 
  to 
  the 
  

   following 
  variety: 
  

  

  ERIOPTERA 
  NIGROLINEATA, 
  var. 
  PUBESCENS, 
  new 
  subspecies. 
  

  

  The 
  head 
  above 
  is 
  uniformly 
  hght 
  grey, 
  the 
  dark 
  stripe 
  of 
  the 
  

   throacic 
  dorsum 
  broad, 
  on 
  the 
  praescutum 
  expanded 
  out 
  over 
  the 
  

   entire 
  sclerite 
  with 
  the 
  exception 
  of 
  the 
  anterior 
  margin 
  and 
  the 
  space 
  

   in 
  front 
  of 
  the 
  pseudo 
  suture. 
  Pleurae 
  greyish 
  with 
  an 
  indistinct 
  

   broad 
  yellowish 
  stripe 
  above 
  the 
  foreleg 
  and 
  running 
  caudad 
  beyond 
  

   the 
  wing 
  basis; 
  wings 
  strongly 
  tinged 
  with 
  yellow 
  at 
  the 
  bases; 
  a 
  

   distinct, 
  though 
  sparse, 
  pubescence 
  in 
  all 
  of 
  the 
  cells 
  of 
  the 
  wings.
