  Andrewes 
  on 
  the 
  

  

  In 
  addition 
  to 
  the 
  type, 
  I 
  have 
  seen 
  only 
  the 
  examples 
  

   taken 
  by 
  Mr. 
  Lewis 
  in 
  Ceylon.

  22. 
  Acupalpus 
  derogatus. 
  Bates 
  (p. 
  80) 
  accepts 
  Walker's 
  

   name, 
  but 
  he 
  gives 
  such 
  a 
  short 
  description 
  that 
  I 
  propose 
  

   to 
  amplify 
  it. 
  The 
  species 
  is 
  apparently 
  confined 
  to 
  Ceylon. 
  

   Walker's 
  type 
  is 
  a 
  very 
  poor 
  specimen. 
  

  

  Acupalpus 
  derogatus. 
  Length 
  35 
  mill. 
  Width 
  125 
  

   mi-11. 
  

  

  Black, 
  8lightly 
  iridescent; 
  mouth-parts, 
  antennae, 
  legs, 
  margin 
  

   of 
  prothorax, 
  and 
  margin 
  and 
  suture 
  of 
  elytra 
  reddish. 
  

  

  Head 
  smooth, 
  wide, 
  convex, 
  frontal 
  foveae 
  short, 
  deep, 
  curved 
  

   towards 
  eye 
  behind, 
  eyes 
  flat, 
  neck 
  not 
  narrowed. 
  

  

  Prothorax 
  rather 
  wider 
  than 
  head, 
  widest 
  at 
  a 
  third 
  from 
  apex, 
  

   a 
  little 
  emarginate 
  in 
  front, 
  truncate 
  behind, 
  sides 
  rounded 
  in 
  front, 
  

   then 
  straight 
  to 
  hind 
  angles, 
  which 
  are 
  obtuse; 
  transverse 
  impres- 
  

   sions 
  and 
  median 
  line 
  all 
  rather 
  famt, 
  basal 
  foveae 
  deep, 
  joining 
  

   marginal 
  channel 
  at 
  sides, 
  surface 
  smooth, 
  shiny. 
  

  

  Elytra 
  shiny, 
  parallel, 
  shoulders 
  well 
  marked, 
  obliquely 
  truncate 
  

   at 
  apex, 
  striae 
  fairly 
  deep, 
  impunctate, 
  a 
  short 
  striole 
  between 
  

   1 
  and 
  2, 
  intervals 
  a 
  little 
  convex, 
  3 
  with 
  a 
  pore 
  rather 
  behind 
  middle, 
  

   marginal 
  series 
  interrupted. 
  

  

  The 
  black 
  colour 
  differentiates 
  this 
  species 
  from 
  its 
  

   Eastern 
  alhes. 
  It 
  is 
  rather 
  similar 
  in 
  form 
  to 
  A. 
  meri- 
  

   dianus 
  Dej., 
  but 
  smaller, 
  thorax 
  more 
  narrowed 
  behind, 
  

   angles 
  more 
  rounded, 
  basal 
  area 
  without 
  punctures, 
  elytra 
  

   a 
  little 
  shorter 
  and 
  more 
  strongly 
  striate, 
  the 
  pore 
  on 
  

   interval 
  3 
  further 
  forward, 
  and 
  distinguished 
  at 
  once 
  by 
  

   the 
  absence 
  of 
  the 
  basal 
  yellow 
  fascia.

  Tachyta 
  (Acupalpus) 
  extrema 
  == 
  T. 
  (Tachys) 
  umbrosa 
  

   Motch. 
  (Bull. 
  Mosc. 
  1851, 
  iv, 
  507). 
  As 
  Bates 
  points 
  out 
  

   (p. 
  151) 
  " 
  only 
  a 
  fragment 
  of 
  Walker's 
  type 
  in 
  the 
  British 
  

   Museum 
  remains 
  for 
  comparison," 
  but 
  he 
  considered 
  

   the 
  two 
  species 
  as 
  being 
  probably 
  identical, 
  and 
  I 
  quite 
  

   agree 
  with 
  him. 
  Schaum 
  described 
  it 
  again 
  (Berl. 
  Ent. 
  

   Zeit. 
  1863, 
  88) 
  under 
  the 
  name 
  of 
  T. 
  nietneri. 
  

  

  It 
  occurs 
  all 
  over 
  S.E. 
  Asia 
  and 
  extends 
  to 
  the 
  Malay 
  

   Archipelago 
  and 
  New 
  Guinea, 
  but 
  is 
  replaced 
  in 
  Australia 
  

   by 
  T. 
  (Bembidium) 
  brunnipennis 
  Macl., 
  jun. 
  (Trans. 
  Ent. 
  

   Soc, 
  N.S.W. 
  1871, 
  ii, 
  118), 
  and 
  in 
  Japan 
  by 
  the 
  palaearctic 
  

   T. 
  {Bembidium) 
  ncma 
  Gylh. 
  (Ins. 
  Suec, 
  ii, 
  1810, 
  30).
