  the

  One 
  male, 
  Aguadilla, 
  Porto 
  Rico, 
  January, 
  1899 
  (A. 
  Busck). 
  

  

  The 
  costal 
  divisions 
  in 
  lugubrina 
  are 
  1-1^-4. 
  In 
  Williston's 
  

   description 
  of 
  luguhris 
  ^ 
  he 
  states 
  that 
  the 
  species 
  has 
  bristles 
  on 
  the 
  

   under 
  side 
  (ventral 
  surface 
  ?) 
  of 
  mid 
  tibia, 
  though 
  I 
  am 
  not 
  sure 
  just 
  

   what 
  he 
  means 
  by 
  that 
  definition, 
  and 
  also 
  that 
  the 
  third 
  section 
  of 
  

   cost 
  a 
  is 
  three 
  times 
  as 
  long 
  as 
  second. 
  His 
  figure 
  gives 
  the 
  third 
  

   section 
  of 
  costa 
  as 
  less 
  than 
  twice 
  the 
  length 
  of 
  second. 
  He 
  heads 
  

   his 
  description 
  "male 
  and 
  female" 
  and 
  says 
  in 
  notes 
  ''one 
  specimen." 
  

  

  ' 
  This 
  name 
  being 
  preoccupied 
  I 
  have 
  altered 
  the 
  name 
  of 
  the 
  species 
  to 
  sublugubrina 
  in 
  Smiths.
