  the 
  ocelli 
  is 
  raised 
  ; 
  there 
  is 
  a 
  broad 
  transverse 
  depression 
  

   behind 
  it 
  ; 
  a 
  thin 
  furrow 
  is 
  on 
  the 
  top 
  of 
  the 
  vertex, 
  and 
  a 
  

   wider 
  one 
  runs 
  down 
  from 
  the 
  ocelli. 
  Clypeus 
  bare, 
  shining, 
  

   impunctate, 
  pale 
  rufous 
  ; 
  the 
  apex 
  margined, 
  projecting 
  in 
  

   the 
  middle. 
  Antennse 
  filiform 
  rather 
  than 
  stout, 
  densely 
  

   covered 
  with 
  a 
  pale 
  pile 
  ; 
  the 
  second 
  joint 
  is 
  one-third 
  the 
  

   length 
  of 
  the 
  third. 
  Pronotum 
  rather 
  depressed, 
  having 
  an

  area 
  shining, 
  impunc- 
  

   tate, 
  bare, 
  the

  margined, 
  but 
  not

  ; 
  the 
  apex 
  

   rather 
  sharply 
  pointed 
  and 
  truncate. 
  The 
  abdominal 
  seg- 
  

   ments 
  bear 
  laterally 
  a 
  dense 
  silvery 
  pubescence 
  forming 
  

   broad 
  bands, 
  which 
  do 
  not 
  reach 
  across. 
  

  

  The 
  quantity 
  of 
  black 
  on 
  the 
  abdomen 
  varies, 
  some 
  

   specimens 
  having 
  the 
  middle 
  segments 
  only 
  slightly 
  infus- 
  

   cated, 
  while 
  others 
  have 
  broad 
  bands 
  on 
  the 
  third 
  — 
  fifth 
  

   segments. 
  Smith, 
  it 
  may 
  be 
  added, 
  does 
  not 
  state 
  that 
  the 
  

   clypeus 
  of 
  Argyrea 
  is 
  rufous.
