  8. 
  (7) 
  Minute 
  sculpture 
  of 
  apices 
  of 
  2nd 
  and 
  3rd 
  segments 
  distinct, 
  

  

  the 
  apical 
  impression 
  of 
  the 
  3rd 
  never 
  polished 
  as 
  in 
  

   saundersella, 
  and 
  generally 
  only 
  shallow. 
  

  

  9. 
  (12) 
  Second 
  abdominal 
  segment 
  always 
  with 
  more 
  or 
  less 
  

  

  numerous 
  punctures, 
  often 
  excessively 
  faintly 
  impressed, 
  

   and 
  difficult 
  to 
  see 
  definitely 
  amongst 
  the 
  surface 
  

   sculpture, 
  nevertheless 
  always 
  to 
  be 
  distinguished 
  in 
  

   one 
  position 
  or 
  another. 
  

  

  10. 
  (11) 
  Basal 
  abdominal 
  segment 
  along 
  the 
  apical 
  margin 
  with 
  

  

  excessively 
  dense 
  sculpture 
  (almost 
  as 
  in 
  spretu) 
  and 
  

   quite 
  dull, 
  the 
  surface 
  there 
  of 
  normal 
  form, 
  only 
  

   ordinarily 
  convex. 
  

   (Stigma 
  pale 
  with 
  dark 
  lower 
  border.) 
  

  

  alfkenella 
  and 
  moricdla. 
  

  

  11. 
  (10) 
  Apical 
  portion 
  of 
  basal 
  segment 
  with 
  the 
  minute 
  sculpture 
  

  

  very 
  fine 
  or 
  feeble, 
  so 
  that 
  in 
  some 
  aspects 
  this 
  part 
  

   appears 
  more 
  or 
  less 
  shining; 
  the 
  surface 
  is 
  imusually 
  

   convex 
  and 
  gives 
  to 
  the 
  apical 
  margin 
  an 
  appearance 
  

   of 
  being 
  thickened 
  (anal 
  appressed 
  hairs 
  darkish 
  fuscous). 
  

  

  falsifica. 
  

  

  12. 
  (9) 
  Second 
  abdominal 
  segment 
  impunctate 
  or 
  nearly, 
  never 
  with 
  

  

  an 
  extensive 
  system 
  of 
  obsolescent 
  puncturation 
  as 
  in 
  

   the 
  preceding, 
  often 
  a 
  few 
  very 
  feeble 
  punctures 
  at 
  the 
  

   sides. 
  

  

  13. 
  (14) 
  Mesonotum 
  and 
  scutellum 
  rugulose 
  all 
  over, 
  dull, 
  with 
  

  

  excessively 
  fine 
  punctures 
  usually 
  hardly 
  visible 
  as 
  

   minute 
  points 
  amidst 
  the 
  sculpture 
  on 
  the 
  former, 
  the 
  

   appressed 
  hairs 
  of 
  5th 
  segment 
  always 
  dark, 
  sometimes 
  

   with 
  more 
  or 
  less 
  golden 
  tint 
  subopaca. 
  

  

  14. 
  (13) 
  Mesonotum 
  and 
  scutellum 
  with 
  closer 
  or 
  larger 
  punctures, 
  

  

  the 
  scutellum 
  (and 
  sometimes 
  the 
  mesonotum) 
  more 
  or 
  

   less 
  shining 
  in 
  some 
  forms, 
  appressed 
  hairs 
  of 
  5th 
  segment 
  

   in 
  some 
  golden. 
  

  

  15. 
  (16) 
  Abdomen 
  in 
  dorsal 
  view 
  with 
  distinct 
  dense 
  apical 
  fringes 
  

  

  of 
  short 
  hairs 
  on 
  the 
  sides 
  of 
  the 
  2nd 
  and 
  3rd 
  segments 
  

   in 
  fresh 
  examples 
  parvula 
  and 
  minutula. 
  

  

  16. 
  (15) 
  Abdomen 
  in 
  dorsal 
  view 
  with 
  the 
  lateral 
  streaks 
  not 
  or 
  

  

  hardly 
  noticeable, 
  and 
  appearing 
  extraordinarily 
  free 
  

   from 
  any 
  special 
  marking 
  in 
  consequence. 
  

  

  parvuloides 
  and 
  minutuloides. 
  

  

  B. 
  (A) 
  Species 
  rarely 
  only 
  7 
  mm. 
  long; 
  one 
  or 
  two 
  agree 
  in 
  most 
  

  

  of 
  the 
  characters, 
  and 
  these 
  small 
  ones 
  have 
  the 
  basal 
  

  

  abdominal 
  segment 
  polished 
  as 
  shown 
  in 
  nana 
  K. 
  alone 
  

  

  of 
  the 
  preceding 
  group, 
  but 
  have 
  not 
  the 
  dense 
  even
