  A 
  very 
  distinct 
  species, 
  with 
  one 
  remarkable 
  characteristic, 
  the 
  possession 
  of 
  

   scales 
  on 
  the 
  postnotum. 
  In 
  some 
  respects, 
  notably 
  the 
  form 
  of 
  the 
  male 
  palpi, 
  

   it 
  resembles 
  0. 
  rusticus, 
  which, 
  it 
  is 
  interesting 
  to 
  note, 
  was 
  taken 
  at 
  the 
  same 
  time 
  

   and 
  place.

  The 
  four 
  dark 
  stripes 
  of 
  the 
  

   mesonotum 
  are 
  brown 
  instead 
  of 
  black, 
  and 
  are 
  separated 
  by 
  narrow 
  golden, 
  instead 
  

   of 
  whitish 
  lines 
  ; 
  the 
  sides 
  of 
  the 
  mesonotum 
  are 
  almost 
  pure 
  white, 
  instead 
  of 
  

   yellowish 
  white 
  ; 
  the 
  scutellar 
  scales 
  are 
  broad, 
  flat 
  and 
  white 
  ; 
  the 
  abdominal 
  seg- 
  

   ments 
  have 
  narrow 
  basal 
  yellowish 
  bands 
  in 
  addition 
  to 
  the 
  white 
  lateral 
  spots 
  ;. 
  

   and 
  the 
  hind 
  femora 
  have 
  a 
  dark 
  dorsal 
  line 
  on 
  the 
  basal 
  half.
