  elongated, 
  swollen 
  at 
  the 
  apex, 
  about 
  half 
  the 
  length 
  of 
  the 
  whole, 
  the 
  apex 
  truncated 
  

   and 
  with 
  some 
  bristle-like 
  hairs 
  and 
  a 
  cup-shaped 
  depression 
  apparently 
  leading 
  

   into 
  an 
  elongate 
  glandular 
  sac. 
  Surface 
  of 
  the 
  third 
  joint, 
  except 
  for 
  the 
  apical 
  

   knob, 
  transversely 
  striated 
  by 
  trachea-like 
  ridges 
  giving 
  a 
  serrated 
  appearance 
  in 
  

   outline 
  ; 
  under 
  a 
  high 
  power 
  the 
  ridges 
  are 
  seen 
  to 
  carry 
  minute 
  bristles 
  and 
  are 
  not 
  

   continuous 
  but 
  broken 
  ; 
  on 
  the 
  second 
  joint 
  the 
  ridges 
  are 
  diagonally 
  arranged 
  

   distally, 
  but 
  disappear 
  proximally, 
  where 
  the 
  minute 
  bristles 
  are 
  irregularly 
  arranged 
  ; 
  

   there 
  are 
  no 
  ridges 
  on 
  the 
  basal 
  joint. 
  

  

  Proboscis 
  longer 
  than 
  the 
  palpi 
  (fig.

  curved 
  slightly 
  backward 
  in 
  nearly 
  all 
  

   specimens 
  ; 
  black 
  in 
  colour 
  and 
  clothed 
  with 
  white 
  flat 
  scales 
  and 
  short 
  greyish 
  

   hairs.

  strongly 
  developed. 
  Clypeus 
  globular, 
  

   black 
  in 
  colour 
  but 
  with 
  greyish 
  reflections.

   hair-like 
  bristles

   bristles 
  below 
  ;
