  the

  By 
  the 
  dull 
  thorax 
  this 
  species 
  resembles 
  Panurginus 
  parvulus 
  Friese 
  

   from 
  San 
  Mateo, 
  Costa 
  Rica; 
  P. 
  parvulus 
  was 
  described 
  from 
  the 
  fe- 
  

   male, 
  4 
  mm. 
  long, 
  and 
  I 
  do 
  not 
  believe 
  it 
  can 
  belong 
  with 
  the 
  Honduras 
  

   insect.

  Female. 
  — 
  Length

  mm.

  rather 
  more; 
  entirely 
  black 
  without 
  light 
  

   markings; 
  head 
  rather 
  broad, 
  face 
  dull; 
  apical 
  half 
  of 
  flagellum 
  brown- 
  

   ish 
  beneath; 
  mesonotum 
  polished; 
  tegulae 
  black; 
  wings 
  dusky; 
  stigma 
  

   large 
  and 
  very 
  dark; 
  first 
  recurrent 
  nervure 
  joining 
  second 
  submarginal 
  

   cell 
  far 
  from 
  base, 
  but 
  second 
  very 
  near 
  apex; 
  abdomen 
  flattened, 
  

   shining, 
  the 
  first 
  tergite

  Honduras: 
  Zamorano,

  taken 
  at 
  flowers 
  

   of 
  Aeschynomene 
  americana

  It 
  was 
  also 
  found 
  8 
  km. 
  west 
  of 
  Dos

  When 
  I 
  first 
  examined 
  this 
  species 
  I 
  thought 
  it 
  was 
  the 
  female 
  of 
  

   H. 
  opacellus, 
  but 
  the 
  shining 
  mesonotum 
  and 
  the 
  position 
  of 
  the 
  

   recurrent 
  nervures 
  make 
  this 
  impossible.
