  Remarks. 
  — 
  This 
  species 
  is 
  evidently 
  very 
  close 
  to 
  A. 
  crassivevxi 
  

   Kertesz, 
  but 
  it 
  differs 
  from 
  the 
  description 
  in 
  a 
  number 
  of 
  details, 
  the 
  

   most 
  important 
  of 
  which 
  is 
  indicated 
  in 
  the 
  key.

  (new

  This 
  species 
  is 
  widely 
  distributed, 
  being 
  known 
  from 
  Amboina, 
  its 
  

   type 
  locality, 
  to 
  Queensland, 
  Australia. 
  I 
  have 
  compared 
  the 
  Solomon 
  

   Islands 
  material 
  with 
  specimens 
  from 
  New 
  Guinea, 
  New 
  Hebrides, 
  

   and 
  Queensland, 
  and 
  find 
  them 
  to 
  be 
  conspecific.
