  A 
  specimen 
  from 
  Caracas, 
  Venezuela, 
  June 
  17, 
  1891, 
  Meinert, 
  

   determined 
  as 
  lunigera 
  by 
  Poppius 
  we 
  provisionally 
  accept 
  as 
  repre- 
  

   senting 
  that 
  species. 
  Considering 
  the 
  diversity 
  of 
  these 
  little 
  in- 
  

   sects 
  and 
  the 
  distance 
  this 
  specimen 
  was 
  taken 
  from 
  the 
  type 
  locality 
  

   of 
  lunigera 
  it 
  may 
  well 
  be 
  a 
  distinct 
  species. 
  Moreover, 
  the 
  specimen 
  

   is 
  in 
  rather 
  poor 
  condition, 
  especially 
  as 
  regards 
  coloration. 
  Evi- 
  

   dently, 
  however, 
  it 
  had 
  a 
  broad 
  lunate 
  pale 
  marking 
  over 
  base 
  of 
  

   forewings 
  as 
  described 
  for 
  lunigera 
  by 
  Reuter. 
  Blackish, 
  a 
  broad 
  

   lunate 
  cream-colored 
  fascia 
  on 
  fore 
  wings 
  extending 
  in 
  middle 
  from 
  

   apex 
  of 
  scutellum 
  to 
  tip 
  of 
  clavus, 
  anterior 
  lateral 
  prolongations 
  

   reaching 
  bases 
  of 
  fore 
  wings 
  near 
  humeral 
  angles 
  ; 
  membrane 
  whitish 
  

   to 
  fumose; 
  legs 
  and 
  antennae 
  testaceous. 
  Pilosity 
  pale, 
  short, 
  and 
  

   depressed 
  ; 
  a 
  few 
  pairs 
  of 
  longer 
  hairs 
  on 
  lower 
  part 
  of 
  face. 
  Dor- 
  

   sum

  Other 
  specimens 
  of 
  both 
  sexes 
  with 
  the 
  following 
  data 
  are 
  as- 
  

   signed 
  to 
  this 
  species.

  There 
  are 
  some 
  differences 
  in 
  this 
  series 
  with 
  respect 
  to 
  the 
  small 
  

   bare 
  spots 
  on 
  head, 
  but 
  we 
  find 
  no 
  other 
  differential 
  characters 
  cor- 
  

   related 
  with 
  them. 
  It 
  may 
  well 
  be 
  that 
  there 
  are 
  distinct 
  species 
  

   in 
  the 
  lunigera 
  group 
  but 
  we 
  are 
  unable 
  to 
  define 
  any 
  at 
  present. 
  

   Van 
  Duzee 
  has 
  described 
  Schizoptera 
  (Gorixidea) 
  doddsi, 
  10 
  but 
  the 
  

   characters 
  assigned 
  do 
  not 
  separate 
  it 
  from 
  lunigera. 
  This 
  has 
  re- 
  

   sulted 
  chiefly 
  from 
  defects 
  in 
  Reuter's 
  figure, 
  which 
  is 
  very 
  poor.
