  on 
  the 
  

  

  front 
  angles 
  porrect, 
  only 
  a 
  little 
  rounded, 
  hind 
  angles 
  right, 
  strongly 
  

   reflexed; 
  surface 
  finely 
  transversely 
  wrinkled, 
  front 
  transverse 
  

   impression 
  obsolete 
  in

  forming 
  a 
  shallow

   side, 
  hind 
  transverse 
  impression 
  deep, 
  median 
  line 
  deep 
  not 
  reaching 
  

   margins, 
  an 
  irregular 
  furrow 
  running 
  for\\ard 
  on 
  each 
  side 
  from 
  

   the 
  ends 
  of 
  the 
  basal 
  transverse 
  impression 
  and 
  ending 
  in 
  a 
  shallow 
  

   fovea 
  situated 
  midway 
  between 
  the 
  median 
  line 
  and 
  the 
  side 
  

   margin, 
  and 
  at 
  about 
  one 
  -third 
  from 
  apical 
  margin. 
  

  

  Elytra 
  twice 
  as 
  wide 
  as 
  thorax, 
  and 
  rather 
  more 
  than 
  twice 
  as 
  

   long, 
  short, 
  widened 
  behind, 
  margin 
  narrow 
  but 
  widened 
  out 
  in 
  

   middle, 
  truncate 
  and 
  emarginate 
  at 
  apex, 
  with 
  a 
  tooth 
  (not 
  a 
  spine) 
  

   at 
  each 
  end 
  of 
  the 
  truncature 
  ; 
  surface 
  finely 
  shagreened, 
  striae 
  

   deep, 
  finely 
  crenulate, 
  intervals 
  raised, 
  third 
  with 
  3 
  pores, 
  1 
  near 
  

   base, 
  2 
  just 
  behind 
  one-third 
  from 
  base, 
  3 
  at 
  four-fifths, 
  ninth 
  with 
  

   a 
  few 
  large 
  (presumably 
  setiferous) 
  punctures, 
  but 
  the 
  only 
  seta, 
  

   visible 
  (and 
  that 
  one 
  on 
  the 
  second 
  specimen) 
  is 
  close 
  to 
  the 
  external 
  

   angle 
  of 
  the 
  truncature. 
  

  

  Underside 
  smooth, 
  shiny, 
  head 
  finely 
  rugose 
  at 
  sides, 
  prostemum 
  

   and 
  ventral

  finely 
  and 
  remotely 
  pimctate, 
  prostemal 
  process 
  

   not 
  bordered, 
  metepistema 
  long 
  and 
  narrow, 
  last 
  ventral 
  segment 
  

   with 
  two 
  setae 
  on 
  each 
  side, 
  the 
  outer 
  one 
  on 
  margin, 
  the 
  inner 
  

   one 
  at 
  some 
  distance 
  from 
  margin. 
  (Front 
  tarsi

  three 
  

   first

  dilated,

  Closely 
  allied 
  to 
  P. 
  longicollis 
  Chaud., 
  but 
  without

   on 
  the

  Head 
  wider,

   thorax 
  wider, 
  front 
  angles 
  more, 
  hind 
  angles 
  less 
  prominent, 
  

   surface 
  flatter 
  with 
  deeper 
  impressions; 
  elytra 
  similar 
  in 
  

   shape,

  Diplochila 
  (Rhembus) 
  polita, 
  Herbst's 
  Carabus 
  in- 
  

   dicus 
  (Fuessly's 
  Archiv. 
  V, 
  ii, 
  1784, 
  138, 
  t. 
  29, 
  f. 
  11) 
  seems 
  

   to 
  be 
  the 
  same 
  species 
  as 
  Fabricius' 
  Carabus 
  politvs 
  (Ent. 
  

   Syst. 
  i, 
  1792, 
  146), 
  and 
  was 
  so 
  considered 
  both 
  by 
  Macleay 
  

   and 
  Chaudoir 
  (Bull. 
  Mosc. 
  1852, 
  i, 
  67). 
  Herbst's 
  name, 
  

   however, 
  has 
  never 
  come 
  into 
  general 
  use, 
  perhaps 
  from 
  

   some 
  doubt 
  about 
  the 
  identification, 
  which 
  I 
  cannot 
  at 
  

   present 
  resolve. 
  Numerous 
  references 
  to 
  the 
  species 
  will 
  

   be 
  found 
  in 
  entomological 
  literature. 
  

  

  The 
  genus 
  Rhembus, 
  under 
  its 
  French 
  name, 
  was 
  first 
  

   mentioned 
  by 
  Latreille 
  (Hist. 
  Nat. 
  et 
  Icon. 
  Col. 
  Eur. 
  1822, 
  

   i, 
  85), 
  but 
  it 
  was 
  first 
  described 
  under 
  its 
  Latin 
  name 
  by 
  

   Dejean 
  (Spec. 
  Gen. 
  ii, 
  1826, 
  380). 
  Meanwhile 
  Germar 
  had 
  

   in 
  1824 
  applied 
  the 
  same 
  name 
  to 
  a 
  genus 
  of 
  CurcuUonidae, 
  

   and 
  Brulle's 
  name 
  of 
  Diplochila 
  (Audouin 
  and 
  Brulle's 
  Hist.
