  Mr. 
  H. 
  E. 
  Andrewes 
  on 
  the 
  

  

  emarginate, 
  eyes 
  moderately 
  prominent, 
  antennae 
  reaching 
  rather 
  

   beyond 
  middle 
  of 
  body. 
  

  

  Pro 
  thorax 
  a 
  shade 
  narrower 
  than 
  head 
  (with 
  eyes), 
  as 
  long 
  as 
  

   wide, 
  widest 
  at 
  a 
  third 
  from 
  apex, 
  a 
  little 
  convex, 
  truncate 
  at 
  

   extremities, 
  but 
  sides 
  of 
  base 
  turn 
  forward 
  to 
  meet 
  hind 
  angles; 
  

   sides 
  narrowly 
  bordered, 
  gently 
  rounded 
  in 
  front, 
  widely 
  but 
  only 
  

   slightly 
  sinuate 
  before 
  hind 
  angles, 
  which 
  are 
  obtuse, 
  with 
  a 
  pore 
  

   and 
  seta 
  just 
  before 
  the 
  angle, 
  a 
  second 
  pore 
  visible 
  at 
  each 
  side 
  

   on 
  the 
  border 
  at 
  a 
  fifth 
  from 
  apex, 
  but 
  the 
  setae 
  have 
  disappeared 
  ; 
  

   front 
  angles 
  rounded, 
  transverse 
  impressions, 
  median 
  line, 
  and 
  basal 
  

   foveae 
  all 
  moderately 
  deep, 
  the 
  last 
  named 
  joining 
  marginal 
  channel; 
  

   surface 
  smooth, 
  shiny, 
  with 
  faint 
  transverse 
  wrinkles. 
  

  

  Elytra 
  nearly 
  three 
  times 
  as 
  long, 
  and 
  a 
  Uttle 
  more 
  than 
  twice 
  

   as 
  wide 
  as 
  prothorax, 
  flat 
  on 
  disk, 
  but 
  rather 
  convex 
  at 
  margins, 
  

   which 
  are 
  explanate 
  behind, 
  shoulders 
  strongly, 
  sides 
  gently 
  rounded, 
  

   apex 
  obliquely 
  truncate, 
  outer 
  angle 
  of 
  truncature 
  rounded, 
  sutural 
  

   angle 
  rather 
  sharp 
  ; 
  striae 
  fairly 
  deep, 
  with 
  large 
  very 
  faint 
  shallow 
  

   pimctures, 
  no 
  scutellary 
  stride, 
  intervals 
  gently 
  convex, 
  3 
  with 
  two 
  

   large 
  punctures 
  occupying 
  the 
  whole 
  width 
  of 
  the 
  interval, 
  one 
  at 
  a 
  

   third 
  from 
  base, 
  the 
  other 
  at 
  a 
  sixth 
  from 
  apex, 
  a 
  third 
  very 
  smaU 
  

   puncture 
  at 
  extreme 
  apex 
  of 
  interval 
  adjoining 
  stria 
  2, 
  some 
  large 
  

   setiferous 
  pimctures 
  along 
  margin. 
  Fourth 
  joint 
  of 
  tarsi 
  strongly 
  

   bilobed; 
  claws 
  pectinate. 
  

  

  I 
  put 
  this 
  species 
  in 
  the 
  genus 
  Tetragonica 
  with 
  some 
  

   hesitation. 
  Walker's 
  specimen 
  is 
  unique, 
  and 
  more 
  

   material 
  is 
  required 
  for 
  dissection. 
  The 
  prothorax 
  is 
  

   more 
  convex 
  and 
  much 
  more 
  narrowed 
  behind 
  than 
  in 
  the 
  

   other 
  described 
  species 
  of 
  the 
  genus, 
  the 
  elytra 
  are 
  shorter, 
  

   with 
  more 
  rounded 
  shoulders, 
  and 
  more 
  squarely 
  truncate 
  

   apex.

  Dolichoctis 
  (Colpodes) 
  marginicollis 
  = 
  D. 
  (Cyrtopterus) 
  

   quadriplagiatus 
  Motch. 
  (Bull. 
  Mosc. 
  1861, 
  i, 
  106, 
  t. 
  9, 
  f. 
  4). 
  

   As 
  already 
  mentioned, 
  both 
  species 
  are 
  identical 
  with 
  

   Walker's 
  D. 
  marginifer, 
  and 
  this 
  is 
  the 
  name 
  which 
  should 
  

   be 
  used. 
  

  

  The 
  species 
  is 
  apparently 
  confined 
  to 
  Ceylon, 
  though 
  

   Bates 
  (Compt. 
  rend. 
  Soc. 
  Ent. 
  Belg. 
  1891, 
  339) 
  mentions 
  

   a 
  solitary 
  specimen 
  from 
  Tetara, 
  differing, 
  however, 
  in 
  

   some 
  respects 
  from 
  the 
  typical 
  form. 
  

  

  27. 
  Diplochila 
  (Platysma) 
  retinens. 
  The 
  genus 
  was 
  

   identified 
  by 
  Bates 
  (p. 
  212) 
  with 
  Chaudoir's 
  Eccoptogenius 
  

   (Bull. 
  Mosc. 
  1852, 
  i, 
  72), 
  and 
  he 
  considered 
  the 
  species 
  

   closely 
  alhed 
  to, 
  if 
  not 
  identical 
  with 
  E. 
  moestus 
  Chaud.
