   callus, 
  though 
  type 
  shows 
  indications 
  that

  the

  but 
  stopping 
  short 
  before 
  reaching 
  

   hind 
  margin, 
  though 
  the 
  fact 
  that 
  it 
  does 
  so 
  may 
  be 
  concealed 
  by 
  greyish-olive 
  

   pollen

  tergite 
  the 
  bicuspid 
  mark 
  is 
  connected 
  with 
  the 
  dusky 
  basal

   is 
  obscured 
  ; 
  venter 
  (except 
  hind 
  borders 
  of 
  second
