  Andrewes 
  on 
  the 
  

  

  Elytra 
  rather 
  short, 
  half 
  as 
  wide 
  again 
  as 
  prothorax, 
  moderately 
  

   convex, 
  square 
  at 
  shoulder, 
  dentate 
  at 
  outer 
  angle 
  of 
  apical 
  trun- 
  

   cature, 
  and 
  close 
  to 
  apex, 
  with 
  a 
  small 
  re-entrant 
  angle 
  at 
  suture, 
  

   sides 
  depressed 
  before 
  middle, 
  with 
  a 
  corresponding 
  sinuation 
  of 
  

   the 
  margin; 
  punctate-striate, 
  a 
  scutellary 
  striole 
  between 
  1 
  and 
  

   suture, 
  intervals 
  smooth, 
  slightly 
  convex, 
  7 
  carinate 
  at 
  base, 
  3 
  with 
  

   three 
  punctures, 
  one 
  near 
  base, 
  one 
  about 
  middle, 
  and 
  one 
  at 
  a 
  

   fourth 
  from 
  apex. 
  

  

  Underside 
  smooth, 
  ventral 
  surface 
  finely 
  and 
  sparsely 
  punctate; 
  

   met3pisterna 
  elongate 
  smooth; 
  two 
  setae 
  on 
  each 
  side 
  of 
  last 
  

   ventral 
  segment. 
  

  

  In 
  form 
  C. 
  reductus 
  resembles 
  C 
  . 
  fuscoaeneus 
  Chaud., 
  but 
  

   the 
  general 
  colour 
  is 
  darker 
  and 
  there 
  is 
  no 
  coppery 
  hue. 
  

   The 
  head 
  is 
  less 
  strongly 
  punctate, 
  the 
  ocular 
  ridges 
  less 
  

   marked 
  and 
  the 
  eyes 
  less 
  prominent, 
  thorax 
  wider, 
  elytral 
  

   intervals 
  flatter 
  — 
  especially 
  5, 
  and 
  apex 
  of 
  each 
  elytron 
  

   bidentate.

  (Bull. 
  Mosc. 
  

   1857, 
  iii, 
  60), 
  an 
  older 
  name. 
  Bates 
  refers 
  to 
  the 
  synonymy 
  

   (p. 
  72).

  Chaudoir, 
  in 
  his 
  

   " 
  Monographic 
  des 
  Scaritides 
  " 
  (Ann. 
  Soc. 
  Ent. 
  Belg. 
  xxii, 
  

   1879, 
  133) 
  identifies 
  the 
  species 
  with 
  0. 
  (Scarites) 
  sculptilis 
  

   West., 
  for 
  further 
  remarks 
  on 
  which 
  see 
  under 
  Westwood, 
  

   Bates 
  (p. 
  210) 
  did 
  not 
  agree 
  with 
  Chaudoir's 
  opinion, 
  nor 
  

   did 
  he 
  consider 
  Walker's 
  species 
  the 
  same 
  as 
  Dejean's 
  

   0. 
  (Scarites) 
  lateralis 
  (Spec. 
  Gen. 
  i, 
  1825, 
  400), 
  in 
  which 
  

   I 
  agree. 
  In 
  these 
  circumstances 
  I 
  give 
  a 
  description 
  of 
  

   the 
  type.
