﻿Types 
  of 
  Oriental 
  Carabidae. 
  185 
  

  

  which 
  Bates 
  described 
  very 
  briefly 
  (p. 
  210), 
  differentiating 
  

   it 
  from 
  D. 
  quadriplagiatus 
  Motch. 
  (Bull. 
  Mosc. 
  1861, 
  

   i, 
  106, 
  t. 
  9, 
  f. 
  4). 
  After 
  examining 
  a 
  number 
  of 
  specimens, 
  

   and 
  noticing 
  considerable 
  differences 
  in 
  the 
  form 
  of 
  the 
  

   thorax 
  and 
  the 
  size 
  of 
  the 
  shoulder 
  spots, 
  I 
  consider 
  that 
  

   D. 
  marginifer 
  is 
  only 
  a 
  small 
  dark 
  example 
  of 
  Motchulsky's 
  

   species. 
  Walker's 
  name 
  is 
  the 
  earlier 
  one. 
  As 
  will 
  be 
  

   seen 
  later 
  on, 
  the 
  species 
  was 
  again 
  described 
  by 
  Walker 
  

   as 
  Colpodes 
  marginicollis. 
  

  

  3. 
  Colpodes 
  (Lebia) 
  bipars. 
  Redescribed 
  by 
  Bates 
  (p. 
  147) 
  

   under 
  the 
  name 
  of 
  Colpodes 
  lampriodes. 
  I 
  think 
  Bates 
  

   must 
  have 
  recognised 
  the 
  identity 
  of 
  the 
  two 
  species, 
  but 
  

   he 
  did 
  not 
  like 
  Walker's 
  description. 
  In 
  this 
  case 
  Walker's 
  

   name 
  must 
  stand. 
  This 
  is 
  apparently 
  the 
  species 
  which 
  

   Chaudoir 
  (Revision 
  des 
  Colpodes, 
  Ann. 
  Soc. 
  Ent. 
  Fr. 
  

   1878, 
  375) 
  mistook 
  for 
  Nietner's 
  Euplynes 
  dohrni. 
  It 
  

   seems 
  to 
  be 
  confined 
  to 
  Ceylon. 
  

  

  4. 
  Catascopus 
  reductus. 
  Another 
  unique 
  specimen. 
  

   Bates 
  gives 
  a 
  short 
  description 
  (p. 
  210), 
  and 
  points 
  out 
  

   that 
  the 
  species 
  is 
  quite 
  different 
  from 
  that 
  which 
  Chaudoir 
  

   mistook 
  for 
  C. 
  reductus 
  (Berl. 
  Ent. 
  Zeit. 
  1861, 
  117). 
  I 
  

   think 
  the 
  latter 
  will 
  prove 
  to 
  be 
  identical 
  with 
  Bates' 
  

   C. 
  cingalensis 
  (p. 
  203). 
  Walker's 
  species 
  requires 
  some 
  

   further 
  description.
