  Sharp 
  on 
  the 
  Rhynchopliorous 
  

  

  inconspicuous, 
  the 
  surface 
  very 
  coarsely 
  and 
  closely 
  punctate, 
  with 
  

   a 
  longitudinal 
  channel 
  extending 
  from 
  the 
  base 
  to 
  in 
  front 
  of 
  the 
  

   middle. 
  Elytra 
  rather 
  deeply 
  striate, 
  interstices 
  broad 
  and 
  flat, 
  

   didl.

  sparingly 
  pubescent,

  setae. 
  Legs, 
  including 
  the 
  

   tarsi, 
  black. 
  In 
  the 
  male 
  the 
  rostrum 
  is 
  short, 
  but 
  in 
  the 
  female 
  

   it 
  is 
  rather 
  longer, 
  and 
  has 
  a 
  well-marked 
  apical 
  portion, 
  which 
  is 
  

   much 
  more 
  slender 
  and 
  shining. 
  

  

  This 
  differs 
  from 
  A. 
  opeticum 
  by 
  the 
  shorter 
  rostrum, 
  

   much 
  more 
  dilated 
  in 
  the 
  middle, 
  and 
  provided 
  with 
  only 
  

   a 
  short 
  apical 
  part 
  : 
  this 
  form 
  of 
  the 
  rostrum 
  also 
  dis- 
  

   tinguishes 
  it 
  from 
  A. 
  cerdo, 
  to 
  which 
  it 
  is 
  equally 
  similar.

  the

  that
