  and 
  sub-acnte 
  : 
  it 
  is 
  produced 
  outwards 
  and 
  forwards 
  ; 
  the 
  ter- 
  

   minal 
  tubercle 
  of 
  the 
  same 
  series 
  is 
  also 
  very 
  large, 
  and 
  it 
  is 
  

   acutely 
  pointed 
  ; 
  between 
  the 
  two, 
  are 
  from 
  three 
  to 
  five* 
  smaller 
  

   (though 
  still 
  tolerably 
  large) 
  pointed 
  tubercles. 
  The 
  hindermost 
  

   tubercle 
  of 
  the 
  inner 
  row 
  is 
  situated 
  at 
  about 
  the 
  commencement 
  

   of 
  the 
  posterior 
  third 
  of 
  the 
  elytra, 
  and 
  is 
  tolerably 
  large 
  ; 
  the 
  

   remaining 
  tubercles 
  of 
  this 
  series 
  (five 
  in 
  number) 
  successively 
  

   decrease 
  in 
  size. 
  Three 
  rows 
  of 
  strong 
  punctures 
  are 
  seen 
  on 
  the 
  

   sides 
  of 
  the 
  elytra, 
  and 
  a 
  row 
  of 
  smaller 
  punctures 
  runs 
  parallel 
  

   with, 
  and 
  close 
  to, 
  the 
  lateral 
  margin. 
  The 
  legs 
  are 
  slender, 
  and 
  

   moderate 
  as 
  to 
  length 
  ; 
  the 
  joints 
  of 
  the 
  tarsi 
  long 
  and 
  narrow, 
  

   the 
  penultimate 
  joint 
  not 
  dilated 
  ; 
  claws 
  moderate, 
  diverging 
  and 
  

   simple. 
  The 
  antennte 
  are 
  clothed 
  with 
  small 
  black 
  hairs.

  This 
  genus 
  is 
  near 
  Polyphrades 
  in 
  its 
  characters 
  ; 
  the 
  general 
  

   form 
  is 
  more 
  elongated, 
  the 
  scape 
  of 
  the 
  antennae 
  is 
  proportion- 
  

   ately 
  stouter, 
  and 
  rather 
  shorter, 
  since 
  it 
  does 
  not 
  reach 
  the 
  eyes 
  ; 
  

   the 
  rostrum 
  is 
  not 
  carinated, 
  and 
  the 
  terminal 
  portion 
  is 
  difl^erently 
  

   constructed 
  ; 
  the 
  tarsi 
  are 
  rather 
  larger, 
  and 
  the 
  anterior 
  coxae 
  

   are 
  separated. 
  The 
  generic 
  name 
  will 
  serve 
  to 
  call 
  attention 
  to 
  

   this 
  last 
  character, 
  which 
  distinguishes 
  Leptostethus 
  from 
  other 
  

   genera 
  of 
  Pachyrhynchidce, 
  to 
  which 
  family 
  it 
  undoubtedly 
  belongs.
