  Lindner 
  has 
  synonymized 
  redhibens 
  with 
  mactans; 
  these 
  two 
  

   forms 
  may 
  be 
  mere 
  color 
  varieties 
  of 
  metallinus, 
  although 
  they 
  may 
  

   be 
  valid 
  geographical 
  subspecies. 
  In 
  redhibens 
  the 
  femora 
  are 
  marked 
  

   with 
  black 
  and 
  the 
  hind 
  tibia, 
  at 
  least, 
  is 
  brown 
  on 
  its 
  basal 
  third 
  ; 
  in 
  

   mactans 
  the 
  femora 
  are 
  wholly 
  yellow 
  and 
  the 
  hind 
  tibia 
  brownish 
  

   on 
  the 
  basal 
  third 
  : 
  in 
  metallinus 
  all 
  femora 
  and 
  tibiae 
  are 
  yellow. 
  The 
  

   United 
  States 
  National 
  Museum 
  has 
  about 
  80 
  specimens. 
  The 
  series 
  

   from 
  the 
  Solomon 
  Islands 
  is, 
  as 
  Lindner 
  found 
  in 
  the 
  material 
  he 
  

   examined, 
  with 
  males 
  of 
  mactans 
  and 
  females 
  of 
  redhihe7}s; 
  in 
  

   other 
  series 
  from 
  Singapore, 
  India, 
  and 
  the 
  Philippine 
  Islands 
  the 
  

   forms 
  mactans 
  and 
  redhibens 
  are 
  represented 
  in 
  both 
  sexes. 
  I 
  can 
  

   find 
  no 
  structural 
  differences. 
  

  

  This 
  species 
  has 
  been 
  recorded
