  5. 
  Ghlaenius 
  quadricolor. 
  This 
  — 
  one 
  of 
  the 
  best-kiiowii 
  

   species 
  of 
  Eastern 
  Chloenms 
  — 
  was 
  originally 
  described 
  by 
  

   Olivier 
  (Enc. 
  Meth. 
  v, 
  1790, 
  344). 
  Later 
  on 
  Dejean 
  (Spec. 
  

   Gen. 
  ii, 
  1826, 
  339) 
  described 
  it 
  under 
  the 
  name 
  of 
  Chlaenius 
  

   orientalis, 
  and 
  Laferte 
  (Ann. 
  Soc. 
  Ent. 
  Fr. 
  1851, 
  263) 
  as 
  

   Amhlygenius 
  chlaenioides. 
  Motchulsky's 
  Poeciloistns 
  laevi- 
  

   collis 
  (Bull. 
  Mosc. 
  1864, 
  iv, 
  348) 
  is 
  probably 
  the 
  same 
  thing. 
  

   It 
  is 
  a 
  common 
  species 
  in 
  India 
  and 
  Ceylon, 
  Bates 
  records 
  

   it 
  from 
  Bhamo, 
  and 
  Mr. 
  Vitalis 
  de 
  Salvaza 
  has 
  taken 
  it 
  in 
  

   Indo-China. 
  I 
  have 
  seen 
  no 
  examples 
  from 
  the 
  Malay 
  

   region, 
  except 
  Java. 
  

  

  The 
  Chlaenius 
  [Carahus) 
  tenuicollis 
  Fab. 
  (Syst. 
  Eleuth. 
  1, 
  

   1801, 
  185) 
  mentioned 
  by 
  Macleay 
  is 
  an 
  African 
  species. 
  

  

  6. 
  Chlaenius 
  micans. 
  Macleay 
  considered 
  his 
  specimen 
  

   identical 
  with 
  Carahus 
  ?nicans 
  Fab. 
  (Ent. 
  Syst. 
  i, 
  1792, 
  151) 
  

   and 
  probably 
  also 
  with 
  Carahus 
  analis 
  Oliv. 
  Neither 
  of 
  

   these 
  species 
  has 
  been 
  satisfactorily 
  identified, 
  and 
  I 
  do 
  not 
  

   know 
  at 
  present 
  where 
  the 
  types 
  are, 
  or 
  even 
  if 
  they 
  are 
  in 
  

   existence. 
  In 
  any 
  case 
  I 
  think 
  C. 
  analis, 
  which 
  came 
  from 
  

   Senegal, 
  may 
  be 
  excluded. 
  Chaudoir 
  (Mon. 
  62) 
  thought 
  

   C. 
  micans 
  Fab. 
  might 
  be 
  the 
  same 
  thing 
  as 
  his 
  C. 
  hamifer 
  

   (Bull. 
  Mosc. 
  1856, 
  iii, 
  209), 
  but 
  that 
  C. 
  inicans 
  Macl. 
  (Mon. 
  

   52) 
  was 
  a 
  different 
  species 
  ; 
  in 
  this 
  latter 
  view 
  I 
  concur, 
  

   though 
  the 
  evidence 
  furnished 
  by 
  Fabricius' 
  very 
  brief 
  

   description 
  is 
  inconclusive. 
  With 
  his 
  original 
  description 
  

   no 
  locality 
  is 
  given, 
  but 
  later 
  on 
  (Syst. 
  Eleuth. 
  i, 
  1801, 
  191) 
  

   he 
  mentions 
  Bengal. 
  As 
  all 
  the 
  examples 
  of 
  Macleay's 
  

   species 
  which 
  I 
  have 
  seen 
  come 
  from 
  the 
  Malay 
  region, 
  I 
  

   redescribe 
  it 
  under 
  the 
  name 
  of 
  C. 
  madeayi.
