  new 
  subspecies 
  

  

  McHe. 
  — 
  This 
  form 
  differs 
  from 
  the 
  typical 
  subspecies 
  in 
  that 
  the 
  

   black 
  stripes 
  of 
  the 
  mesonotum 
  are 
  much 
  broader, 
  occupying 
  approxi- 
  

   mately 
  the 
  median 
  half 
  of 
  the 
  mesonotum 
  and 
  separated 
  only 
  by 
  a 
  

   narrow 
  golden 
  line 
  ; 
  the 
  base 
  of 
  the 
  scutellum, 
  except 
  for 
  a 
  spot 
  at 
  the 
  

   center, 
  is 
  likewise 
  black 
  ; 
  the 
  pile 
  of 
  the 
  pleura 
  is 
  uniformly 
  golden 
  ; 
  

   and 
  the 
  yellow 
  margins 
  of 
  the 
  abdomen 
  are 
  broader 
  and 
  less 
  distinctly 
  

   defined.

  Remarks. 
  — 
  The 
  characters 
  on 
  which 
  this 
  subspecies 
  is 
  based 
  are 
  all 
  

   relative, 
  and 
  may 
  be 
  due 
  to 
  individual 
  variation. 
  However, 
  since 
  a 
  

   stud}' 
  of 
  other 
  members 
  of 
  this 
  family 
  seems 
  to 
  indicate 
  the 
  existence 
  

   of 
  geographical 
  subspecies 
  in 
  some 
  cases 
  on 
  the 
  various 
  islands 
  or 
  

   groups 
  of 
  islands 
  it 
  is 
  probable 
  that 
  this 
  subspecies 
  is 
  valid.
