  impressions 
  on 
  the 
  apices 
  of 
  the 
  2nd 
  and 
  following 
  

  

  segments 
  are 
  deep, 
  dull 
  and 
  very 
  densely 
  sculptured, 
  

   with 
  the 
  appearance 
  of 
  excessively 
  close, 
  minute 
  punc- 
  

   turation; 
  the 
  basal 
  segment 
  is 
  similarly 
  sculptured

  margin;

  Sculpture 
  of 
  apices 
  of 
  the 
  first 
  three 
  abdominal 
  segments 
  

  

  not 
  dense 
  enough 
  to 
  make 
  them 
  dull 
  as 
  in 
  the 
  preceding, 
  

   often 
  the 
  apices 
  of 
  some 
  or 
  all 
  of 
  them 
  are 
  shining 
  in 
  

   some 
  aspects.

  Second 
  and 
  3rd 
  abdominal 
  segments 
  with 
  strong 
  apical 
  

  

  impressions 
  (especially 
  the 
  3rd) 
  which 
  in 
  most 
  aspects 
  

   are 
  brightly 
  shining 
  or 
  highly 
  polished, 
  the 
  surface 
  

   sculpture 
  feeble 
  or 
  hardly 
  visible;

  (82) 
  Second 
  and 
  3rd 
  segments 
  with 
  the 
  impressions 
  shallower 
  

  

  and 
  the 
  surface 
  sculpture 
  much 
  more 
  evident, 
  so 
  that 
  

   in 
  most 
  aspects 
  the 
  surface 
  is 
  much 
  less 
  polished 
  than 
  

   in 
  the 
  preceding.

  Fifth 
  antennal 
  joint

  transverse, 
  not 
  much 
  longer 
  

  

  than 
  the

  the 
  3rd 
  as 
  long, 
  or
