﻿Types 
  of 
  Oriental 
  Carahidae. 
  153 
  

  

  of 
  Amara 
  have 
  nothing 
  to 
  do 
  with 
  that 
  genus, 
  which 
  is 
  a 
  

   palaearctic 
  one. 
  His 
  A. 
  tricolor 
  is 
  the 
  $ 
  of 
  Hypharpax 
  

   lateralis, 
  and 
  I 
  shall 
  refer 
  to 
  it 
  again 
  under 
  that 
  species. 
  

  

  22. 
  Gnathaphanus 
  (Amara) 
  subolivaceus. 
  

  

  23. 
  Gnathaphanus 
  (Amara) 
  subaeneus. 
  

  

  There 
  is 
  one 
  example 
  of 
  each 
  species. 
  I 
  see 
  no 
  reason 
  

   to 
  doubt 
  their 
  identity, 
  and 
  I 
  give 
  a 
  description 
  below.

  rounded,

  the 
  odd 
  intervals

  wider 
  

   near
