  the

  Clypeus

  with 
  fulvescent 
  or 
  brown 
  hairs

  it

  Fourth

  brown-tinged 
  basally.)

  (124) 
  The 
  4th 
  antennal 
  joint 
  appears 
  distinctly 
  elongate, 
  

  

  sometimes 
  as 
  long 
  as 
  the 
  3rd; 
  propodeum 
  never 
  

   sculptured

  of

  Fourth 
  abdominal 
  segment 
  without 
  an 
  entire

  almost 
  

  

  unbroken 
  narrow 
  apical 
  band, 
  this 
  and

  most 
  remnants 
  of

  of 
  clypeus 
  white 
  in 
  fresh 
  examples, 
  3rd 
  antennal 
  

   joint 
  a 
  little 
  longer 
  than 
  the 
  4th.)

  (128) 
  If 
  not 
  abraded 
  the 
  3rd 
  and 
  4th 
  segments 
  of 
  the 
  abdomen 
  

  

  have 
  pale 
  fasciae, 
  that 
  on 
  the 
  3rd 
  either 
  entire 
  or 
  

   interrupted 
  on 
  the 
  middle 
  3rd 
  of 
  the 
  segment, 
  that 
  

   on 
  the 
  4th 
  entire 
  or 
  at 
  least 
  almost 
  uninterrupted 
  in 
  

   the 
  middle.

  (131)* 
  In 
  good 
  specimens 
  the 
  3rd 
  segment 
  has 
  a 
  distinctly 
  

  

  entire 
  or 
  hardly 
  perceptibly 
  broken 
  band, 
  and 
  the 
  

   antennae 
  are 
  always 
  shorter 
  than 
  in 
  the 
  following, 
  

  

  but 
  vary 
  in 
  details

  (130) 
  The 
  band 
  on 
  the 
  3rd 
  segment 
  is 
  interrupted 
  or 
  very 
  

   indistinct 
  for 
  a 
  space 
  about 
  equal 
  to 
  one-fourth 
  or 
  

   one-third 
  the 
  width 
  of 
  this 
  segment; 
  the 
  antennae 
  

   are 
  more 
  elongate 
  wilkella.

  I 
  cannot 
  satisfactorily 
  tabulate 
  these 
  species 
  from 
  worn 
  

   examples, 
  as 
  they 
  can 
  be 
  distinguished 
  only 
  by 
  slight 
  characters 
  

   (differing 
  only 
  in 
  degree) 
  if 
  abraded.
