  abdominal 
  segments 
  as 
  densely 
  punctured 
  

  

  as 
  possible, 
  with 
  the 
  general 
  surface 
  glabrous, 
  and 
  

   complete 
  pale 
  fasciae 
  of 
  dense 
  minute 
  hairs

  the

  of 
  their

  impressions;

  hairs 
  of 
  the

   segment

   (Floccus 
  of 
  hind 
  trochanters

  the 
  hairs

  the 
  

   basal 
  portion 
  too 
  straight

  If

  fill 
  the

  2nd

  3rd 
  segments, 
  either 
  the 
  2nd

  is 
  

   pubescent 
  or 
  the

  is 
  not

  basal

   distinctly 
  punctured 
  on 
  the

  scopal

  above 
  

   the

  and

  hairs 
  of 
  5th

   dark

  (31) 
  If

  either 
  the 
  

  

  basal 
  abdominal 
  segment 
  is 
  not 
  polished 
  or 
  the 
  anal 
  

   fringe 
  is 
  golden. 
  

  

  33. 
  (42) 
  The 
  abdomen 
  has 
  broad 
  pubescent 
  apical 
  bands 
  on 
  the 
  

  

  segments, 
  and 
  the 
  tibiae 
  and 
  their 
  scopae 
  are 
  evidently 
  

   abnormal; 
  the 
  former 
  wide 
  at 
  the 
  apex 
  and 
  therefore 
  

   more 
  clavate 
  than 
  usual 
  (Pi. 
  XII, 
  f. 
  10), 
  the 
  scopal 
  fringe 
  

   above 
  them 
  dense 
  and 
  short 
  in 
  proportion 
  to 
  the 
  apical 
  

   width 
  of 
  the 
  joint, 
  while 
  on 
  its 
  outer 
  side 
  the 
  hairs 
  are 
  

   less 
  dense 
  and 
  finer 
  than 
  usual 
  and 
  those 
  that 
  curve 
  

   upwards 
  from 
  beneath 
  less 
  curved 
  and 
  conspicuous. 
  

   (Floccus 
  in 
  most 
  species 
  distinctly, 
  but 
  in 
  fuscipes 
  hardly, 
  

   imperfect.) 
  

  

  * 
  It 
  is 
  important 
  to 
  notice 
  that 
  the 
  bands 
  are 
  formed 
  of 
  hairs 
  

   that 
  spring 
  from 
  almost 
  the 
  whole 
  surface 
  of 
  the 
  apical 
  impressions, 
  

   as 
  otherwise 
  some 
  ovatula 
  might 
  be 
  confused 
  with 
  the 
  species 
  

   falling 
  under 
  the 
  above 
  head. 
  When 
  worn 
  and 
  abraded, 
  flavipes 
  

   and 
  gravida 
  remain 
  easily 
  distinguishable 
  by 
  the 
  extremely 
  dense 
  

   and 
  fine 
  puncturation 
  of 
  the 
  apical 
  impressions 
  considered 
  in 
  con- 
  

   junction 
  with 
  the 
  other 
  characters 
  given 
  above. 
  Not 
  infrequently 
  

   the 
  bands 
  are 
  slightly 
  interrupted 
  in 
  the 
  middle 
  in 
  caught 
  specimens, 
  

   but 
  this 
  is 
  not 
  the 
  natural 
  condition.
