  I 
  believe 
  that 
  eventually 
  consobrina 
  (Bigot) 
  and 
  maculipennis 
  

   (Macquart) 
  will 
  be 
  proven 
  synonymous, 
  the 
  latter 
  name 
  holding 
  

   priority. 
  The 
  main 
  characters 
  for 
  distinguishing 
  the 
  two 
  are 
  the 
  color 
  

   of 
  the 
  femora 
  and 
  the 
  extent 
  of 
  the 
  infuscated 
  area 
  at 
  the 
  wing 
  apex; 
  

   in 
  maculipennis 
  all 
  femora 
  are 
  broadly 
  yellow 
  basally 
  and 
  the 
  in- 
  

   fuscation 
  of 
  the 
  wing 
  extends 
  to 
  the 
  apex, 
  whereas 
  in 
  consobrina 
  all 
  

   femora 
  are 
  entirely 
  black, 
  and 
  the 
  extreme 
  apex 
  of 
  the 
  wing 
  becomes 
  

   subhyaline. 
  The 
  Solomon 
  Islands 
  specimens 
  have 
  at 
  most 
  a 
  trace 
  of 
  

   yellow 
  at 
  the 
  bases 
  of 
  the 
  femora, 
  usually 
  the 
  femora 
  are 
  wholly 
  

   black. 
  In 
  the 
  Guadalcanal 
  specimens 
  the 
  wing 
  apex 
  is 
  always 
  sub- 
  

   hyaline; 
  in 
  the 
  others 
  it 
  is 
  variable, 
  but 
  more 
  commonly 
  the 
  entire 
  

   apical 
  area 
  is 
  infuscated. 
  If 
  two 
  geographical 
  subspecies 
  are 
  present, 
  

   intergradation 
  occurs 
  over 
  a 
  very 
  wide 
  area, 
  extending 
  from 
  the 
  Solo- 
  

   mons 
  through 
  New 
  Guinea 
  to 
  the 
  Philippine 
  Islands. 
  The 
  type 
  local- 
  

   ity 
  of 
  consobrina 
  is 
  "New 
  Guinea"; 
  that 
  of 
  iTiaculipennis 
  is 
  Manila,

  in 
  contact 
  with 
  second 
  segment,

   higher 
  than
