  margin 
  straight 
  (except 
  at 
  sides), 
  more 
  rounded 
  than 
  is 
  show-n 
  in 
  

   the 
  figure, 
  more 
  contracted 
  in 
  front 
  than 
  behind, 
  sinuate 
  before 
  

   hind 
  angles; 
  front 
  angles 
  rounded 
  and 
  hardly 
  prominent, 
  hind 
  

   ones 
  also 
  rounded 
  with 
  a 
  minute 
  indentation 
  at 
  the 
  angles 
  ; 
  sides 
  

   broadly 
  reflexed, 
  especially 
  towards 
  base; 
  median 
  furrow 
  rather 
  

   faint; 
  the 
  whole 
  surface 
  covered 
  with 
  large 
  confluent 
  punctures, 
  

   giving 
  it 
  a 
  very 
  rough 
  appearance. 
  

  

  Elytra 
  long, 
  nearly 
  parallel, 
  shoulders 
  not 
  very 
  much 
  rounded; 
  

   border 
  narrow, 
  a 
  little 
  sinuate 
  before 
  apex; 
  punctate-striate, 
  striae 
  

   deep, 
  intervals 
  convex 
  and 
  closely 
  punctured, 
  third 
  interval 
  with 
  

   three 
  punctures, 
  1 
  just 
  before 
  middle, 
  2 
  and 
  3 
  close 
  together 
  at 
  

   about 
  two-thirds 
  from 
  base 
  ; 
  front 
  orange 
  spot 
  narrow, 
  transverse, 
  

   at 
  one-fourth 
  from 
  base, 
  covering 
  intervals 
  4-8 
  (in 
  the 
  type 
  a 
  little 
  

   colour 
  shows 
  on 
  3), 
  the 
  colour 
  on 
  6 
  extending 
  furthest 
  towards 
  

   apex, 
  and 
  on 
  8 
  towards 
  base, 
  though 
  in 
  each 
  case 
  only 
  a 
  little 
  

   way; 
  hind 
  spot 
  at 
  tlu'ee 
  -fourths, 
  resembling 
  front 
  one, 
  but 
  colour 
  

   extending 
  furthest 
  towards 
  base 
  on 
  6 
  (in 
  the 
  type 
  hardly 
  any 
  colour 
  

   is 
  visible 
  on 
  3 
  or 
  8). 
  Epistema 
  and 
  sides 
  of 
  sterna 
  and 
  ventral 
  

   surface 
  very 
  coarsely 
  punctate, 
  metepistema 
  rather 
  longer 
  than 
  

   wide, 
  median 
  line 
  of 
  body 
  finely 
  but 
  sparsely 
  punctate 
  and 
  a 
  little 
  

   transversely 
  inigose, 
  prosternal 
  process 
  indistinctly 
  bordered, 
  front 
  

   margin 
  of 
  ventral 
  segments 
  apparently 
  not 
  crenulate, 
  a 
  few 
  large 
  

   punctures 
  on 
  each 
  side 
  of 
  last 
  one, 
  a 
  little 
  removed 
  from 
  margin. 
  

  

  I 
  have 
  compared 
  the 
  type 
  with 
  a 
  specimen 
  of 
  C. 
  regalis 
  

   Gory 
  (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1833, 
  213), 
  to 
  which' 
  it 
  seems 
  

   nearly 
  related. 
  The 
  insect 
  is 
  smaller, 
  the 
  prothorax 
  has 
  

   not 
  the 
  Lebia-]ike 
  produced 
  base 
  of 
  C. 
  regalis, 
  the 
  punctura- 
  

   tion 
  of 
  the 
  elytra 
  is 
  closer 
  and 
  finer, 
  the 
  yellow 
  bands 
  are 
  

   narrower, 
  extending 
  inwards 
  to 
  stria 
  3 
  only, 
  instead 
  of 
  

   to 
  1 
  in 
  front 
  and 
  2 
  behind 
  as 
  in 
  regalis. 
  

  

  Olivier. 
  

  

  There 
  is 
  in 
  the 
  Banks 
  Collection 
  the 
  type 
  of 
  a 
  Carabid 
  

   described 
  by 
  Olivier 
  under 
  the 
  name 
  of 
  Carahus 
  trimacu- 
  

   latus. 
  It 
  bears 
  no 
  locality 
  label, 
  and 
  Olivier 
  did 
  not 
  know 
  

   where 
  it 
  came 
  from. 
  It 
  is 
  probably 
  due 
  to 
  this 
  fact 
  that 
  

   the 
  species 
  has 
  been 
  overlooked, 
  and 
  no 
  references 
  to 
  

   it 
  have, 
  as 
  far 
  as 
  I 
  know, 
  appeared 
  in 
  entomological 
  

   literature. 
  

  

  Macrochilus 
  (Carabus) 
  trimaculatus 
  (Enc. 
  Meth. 
  Ins, 
  ii, 
  

   1790, 
  347, 
  t. 
  179, 
  f. 
  11; 
  Ent. 
  iii, 
  1795, 
  35, 
  88, 
  t. 
  7, 
  f. 
  85). 
  

   An 
  examination 
  of 
  this 
  insect 
  showed 
  at 
  once 
  that 
  it 
  was 
  

   identical 
  with 
  Hope's 
  Macrocliilus 
  bensoni 
  (Col. 
  Man. 
  ii,
