  authority

  therefore 
  conjecture 
  it 
  

   to

  a

  The

  small, 
  few,

  sometimes 
  distorted

  we 
  

   are 
  not 
  quite 
  sure, 
  therefore, 
  whether 
  they 
  have

  Stenotritus 
  elegans,

  variety

  A 
  female 
  from 
  Tennant's 
  Creek, 
  Central 
  Australia 
  [Field; 
  

   Nat. 
  Mus. 
  Victoria, 
  46), 
  has 
  apparently 
  been 
  in 
  alcohol, 
  and 
  

   the 
  pubescence 
  is 
  in 
  bad 
  condition. 
  So 
  far 
  as 
  can 
  be 
  made 
  

   out, 
  there 
  is 
  no 
  fuscous 
  hair 
  on 
  the 
  thorax 
  above, 
  and 
  no 
  

   black 
  hair 
  on 
  the 
  abdomen. 
  The 
  mesothorax 
  shows 
  olive- 
  

   green 
  tints 
  in 
  front. 
  The 
  first 
  r. 
  n. 
  joins 
  the 
  second 
  s.m. 
  a 
  

   little 
  before 
  the 
  middle, 
  instead 
  of 
  a 
  little 
  beyond 
  as 
  in 
  

   Smithes 
  type 
  of 
  S. 
  elegans. 
  Possibly 
  this 
  is 
  a 
  distinct 
  

   species, 
  but 
  it 
  cannot 
  be 
  satisfactorily 
  separated 
  without 
  

   better 
  material. 
  

  

  No 
  males 
  assigned 
  to 
  Stenotritus 
  are 
  known 
  ; 
  but 
  it 
  seems
