  24. 
  Tachys 
  (Bembidium) 
  finitimus. 
  A 
  single 
  specimen, 
  

   and 
  also 
  a 
  very 
  poor 
  one. 
  Bates 
  gives 
  some 
  account 
  of 
  

   it, 
  but 
  his 
  description 
  is 
  so 
  short 
  that 
  I 
  give 
  some 
  further 
  

   particulars. 
  

  

  Tachys 
  finitimus. 
  Length 
  (approx.) 
  2*5 
  mill. 
  Width 
  

   (approx.) 
  rS 
  mill. 
  

  

  Dark 
  brown, 
  elytra 
  reddish, 
  but 
  darker 
  along 
  suture 
  and 
  at 
  

   margins, 
  labrum, 
  joint 
  1 
  and 
  base 
  of 
  joint 
  2 
  of 
  antennae 
  (rest 
  darker), 
  

   and 
  legs 
  testaceous. 
  (The 
  elytra 
  are 
  partially 
  dissociated 
  from 
  the 
  

   body, 
  and, 
  being 
  translucent, 
  probably 
  appear 
  lighter 
  in 
  colour 
  

   than 
  they 
  really 
  are). 
  

  

  Head 
  smooth, 
  not 
  contracted 
  behind, 
  eyes 
  moderately 
  prominent, 
  

   labrum 
  slightly 
  emarginate, 
  frontal 
  grooves 
  short 
  but 
  fairly 
  deep, 
  

   bounded 
  by 
  an 
  external 
  ridge, 
  as 
  in 
  T. 
  haemorrhoidalis 
  Dej. 
  

  

  Prothorax 
  transverse, 
  widest 
  rather 
  before 
  middle, 
  wider 
  than 
  

   head, 
  front 
  emarginate, 
  base 
  slightly 
  arcuate; 
  sides 
  rounded, 
  

   sinuate 
  just 
  before 
  hind 
  angles, 
  narrowly 
  bordered, 
  a 
  seta 
  at 
  two- 
  

   fifths 
  from 
  apex 
  and 
  another 
  at 
  hind 
  angle, 
  front 
  angles 
  quite 
  rounded, 
  

   hind 
  angles 
  right; 
  front 
  transverse 
  stria 
  obsolete, 
  hind 
  one 
  well 
  

   marked, 
  punctured, 
  median 
  stria 
  very 
  faint, 
  not 
  ending 
  in 
  a 
  pmicture 
  

   behind, 
  basal 
  foveae 
  bounded 
  outwardly 
  by 
  a 
  fine 
  carina. 
  

  

  Elytra 
  half 
  as 
  wide 
  again 
  as 
  prothorax, 
  with 
  two 
  sutural 
  im- 
  

   pressed 
  striae, 
  the 
  front 
  discal 
  pore 
  and 
  seta 
  at 
  a 
  third 
  from 
  base, 
  

   hind 
  one 
  at 
  a 
  little 
  more 
  than 
  a 
  third 
  from 
  apex, 
  the 
  inner 
  stria 
  

   extends 
  in 
  each 
  direction 
  rather 
  beyond 
  the 
  pores, 
  eighth 
  stria 
  

   entire, 
  with 
  three 
  or 
  four 
  setiferous 
  pores 
  along 
  its 
  course. 
  

  

  Very 
  close 
  to 
  Bates' 
  T. 
  peryphinus 
  (p. 
  153), 
  but 
  dis- 
  

   tinguishable 
  by 
  the 
  (apparently) 
  reddish 
  elytra, 
  only 
  1| 
  

   (instead 
  of 
  3|) 
  basal 
  joints 
  of 
  the 
  antennae 
  testaceous, 
  and 
  

   the 
  fact 
  that 
  the 
  median 
  line 
  does 
  not 
  terminate 
  in 
  a 
  fovea 
  

   at 
  the 
  base. 
  

  

  25. 
  Tetragonica 
  (Dromius) 
  repandens. 
  Another 
  unique 
  

   specimen. 
  Bates 
  says 
  only 
  a 
  few 
  words 
  about 
  it 
  (p. 
  210), 
  

   so 
  I 
  give 
  below 
  a 
  rather 
  longer 
  description. 
  

  

  Tetragonica 
  repandens. 
  Length 
  375 
  mill. 
  Width 
  1*25 
  

   mill. 
  

  

  Brown, 
  disk 
  of 
  elytra 
  (except 
  suture) 
  light 
  brown; 
  palpi 
  and 
  

   labrum 
  testaceous; 
  border 
  of 
  prothorax 
  and 
  head 
  pitch 
  black, 
  

   latter 
  a 
  little 
  lighter 
  on 
  vertex 
  ; 
  upper 
  surface 
  finely 
  shagreened. 
  

  

  Head 
  smooth, 
  shiny, 
  convex, 
  frontal 
  foveae 
  shallow, 
  bounded 
  

   externally 
  by 
  a 
  short 
  ridge 
  running 
  from 
  middle 
  of 
  eye 
  to 
  base 
  

   of 
  antennae, 
  clypeus 
  with 
  a 
  seta 
  on 
  each 
  side, 
  labrum 
  slightly
