  The 
  species 
  is 
  not 
  unlike 
  C. 
  huchanani 
  Hope, 
  but 
  it 
  is 
  

   considerably 
  larger, 
  and 
  rather 
  narrower. 
  Prothorax 
  re- 
  

   latively 
  wider 
  and 
  more 
  rounded, 
  front 
  margin 
  more 
  

   strongly 
  emarginate, 
  angles 
  more 
  rounded, 
  and 
  sides 
  

   more 
  widely 
  reflexed. 
  The 
  second 
  puncture 
  on 
  the 
  third 
  

   elytral 
  interval 
  is 
  placed 
  a 
  little 
  further 
  towards 
  apex, 
  

   and 
  the 
  suture 
  is 
  not 
  mucronate 
  at 
  the 
  apex. 
  Both 
  tibiae 
  

   and 
  tarsi 
  are 
  without 
  grooves.

  C. 
  amoenus 
  Chaud. 
  (Ann. 
  Soc. 
  

   Ent. 
  Fr. 
  1859, 
  326). 
  Mentioned 
  by 
  Chaudoir 
  in 
  his 
  

   Monograph 
  (I.e. 
  359) 
  among 
  the 
  species 
  miknown 
  to 
  

   him, 
  and 
  also 
  referred 
  to 
  vaguely 
  in 
  the 
  " 
  Revision 
  " 
  

   (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1878, 
  367). 
  Morawitz 
  (Bull. 
  Ac. 
  St. 
  

   Pet, 
  V, 
  1863, 
  324) 
  described 
  the 
  species 
  again 
  from 
  Japan 
  

   under 
  the 
  name 
  of 
  C. 
  splendens. 
  

  

  It 
  has 
  a 
  wide 
  range 
  from 
  India 
  and 
  Ceylon 
  to 
  Japan. 
  

   Bates 
  also 
  records 
  it 
  from 
  Java, 
  and 
  this 
  is 
  quite 
  probable, 
  

   as 
  I 
  have 
  an 
  example 
  taken 
  by 
  Dr. 
  M. 
  Cameron 
  in 
  the 
  

   Malay 
  Peninsula.

  Pterostichus 
  (Omaseus) 
  aeratus,

  Width 
  55 
  mill. 
  

  

  I 
  take 
  these 
  together 
  because 
  I 
  think 
  they 
  are 
  probably 
  

   the 
  same 
  species, 
  but 
  the 
  type 
  of 
  P. 
  aeratus 
  is 
  in 
  such 
  

   poor 
  condition 
  that 
  I 
  cannot 
  state 
  this 
  with 
  certainty. 
  

   There 
  are 
  only 
  the 
  two 
  types 
  in 
  the 
  British 
  Museum 
  

   Collection, 
  nor 
  have 
  I 
  seen 
  any 
  other 
  examples 
  elsewhere. 
  

   In 
  structure 
  the 
  two 
  specimens 
  agree, 
  but 
  in 
  aeratus 
  the 
  

   head, 
  margins 
  of 
  prothorax 
  and 
  elytra, 
  and 
  first 
  joint 
  of 
  

   the 
  antennae 
  are 
  brassy, 
  whereas 
  in 
  indicus 
  the 
  whole 
  

   insect 
  is 
  black, 
  and, 
  as 
  it 
  is 
  a 
  male, 
  the 
  surface 
  is 
  rather 
  

   more 
  shiny 
  than 
  in 
  the 
  female 
  aeratus. 
  I 
  have 
  not 
  found 
  

   any 
  references 
  in 
  later 
  writers, 
  so 
  I 
  give 
  a 
  description 
  : 
  — 
  

  

  Head 
  smooth, 
  with 
  shallow 
  frontal 
  foveae, 
  neck 
  wide 
  and 
  rather 
  

   tumid. 
  Antennae 
  reaching 
  a 
  little 
  beyond 
  the 
  base 
  of 
  prothorax; 
  

   palpi 
  a 
  little 
  narrowed 
  at 
  apex 
  and 
  truncate. 
  Prothorax 
  one-third 
  

   as 
  wide 
  again 
  as 
  head, 
  transverse, 
  width 
  to 
  length 
  about 
  4 
  to 
  3 
  

   (in 
  aeratus 
  the 
  prothorax 
  appears 
  rather 
  wider 
  than 
  in 
  indicus, 
  

   but 
  it 
  is 
  damaged 
  and 
  the 
  wider 
  appearance 
  may 
  be 
  due 
  to 
  this 
  

   cause); 
  slightly 
  emarginate 
  in 
  front 
  and 
  also 
  (over 
  the 
  median 
  

   portion 
  of 
  the 
  base) 
  behind 
  ; 
  sides 
  rounded 
  in 
  front, 
  sinuate 
  behind, 
  

   reflexed 
  margin 
  well 
  marked, 
  a 
  pore 
  and 
  seta 
  at 
  one 
  -third 
  from 
  

   apex, 
  and 
  another 
  at 
  base 
  near 
  hind 
  angle 
  (this 
  latter 
  is 
  only 
  visible 
  

   in 
  aeratus); 
  front 
  angles 
  rounded, 
  hind 
  angles 
  about 
  right, 
  very
