  m 
  the 
  

  

  Underside 
  (as 
  far 
  as 
  it 
  can 
  be 
  seen) 
  smooth, 
  prostemal 
  process 
  

   very 
  finely 
  bordered 
  at 
  apex, 
  metepisterna 
  elongate. 
  

  

  The 
  elytra 
  differ 
  in 
  colour 
  from 
  those 
  of 
  C. 
  facialis 
  Wied., 
  

   and 
  the 
  size 
  is 
  much 
  smaller, 
  head 
  with 
  two 
  carinae 
  on 
  

   each 
  side 
  (instead 
  of 
  one), 
  front 
  angles 
  of 
  prothorax 
  less 
  

   projecting, 
  hind 
  angles 
  acute 
  and 
  projecting 
  (instead 
  of 
  

   right), 
  elytra 
  shorter, 
  fourth 
  interval 
  depressed 
  near 
  base, 
  

   outer 
  angles 
  of 
  apical 
  truncature 
  rounded 
  instead 
  of 
  

   toothed. 
  

  

  3. 
  Hexagonia 
  terminata 
  (Trans. 
  Linn. 
  Soc. 
  xiv, 
  1825, 
  

   564). 
  Kirby's 
  genus 
  was 
  subsequently 
  described 
  by 
  

   Dejean 
  (Spec. 
  Gen. 
  v, 
  1831, 
  288) 
  under 
  the 
  name 
  of 
  Trigono- 
  

   dactyJa. 
  It 
  has 
  been 
  dealt 
  with 
  by 
  numerous 
  authors, 
  

   the 
  latest 
  of 
  whom. 
  Commandant 
  Dupuis, 
  gives 
  details 
  

   of 
  the 
  genus 
  and 
  a 
  list 
  of 
  the 
  species 
  and 
  their 
  synonymy 
  

   (Gen. 
  Ins. 
  Hexagoniinae 
  1913, 
  2). 
  In 
  this 
  list 
  we 
  read, 
  

   " 
  19 
  ? 
  (Description 
  insuffisante) 
  H. 
  terminata 
  Kirby, 
  etc.," 
  

   from 
  which 
  the 
  casual 
  mquirer 
  is 
  left 
  in 
  some 
  doubt 
  whether 
  

   the 
  genotype 
  belongs 
  to 
  the 
  genus 
  at 
  all. 
  Kirby's 
  descrip- 
  

   tion 
  is 
  certainly 
  a 
  very 
  poor 
  one, 
  as 
  was 
  pointed 
  out 
  by 
  

   Schmidt-Goebel 
  (Faun. 
  Col. 
  Birm. 
  1846, 
  50), 
  who 
  discusses 
  

   both 
  genus 
  and 
  species 
  at 
  some 
  length. 
  Lacordaire 
  (Gen. 
  

   Col. 
  i, 
  1854, 
  Atl. 
  t. 
  3, 
  f. 
  1) 
  gives 
  a 
  figure 
  alleged 
  to 
  be 
  

   Trigonodactyla 
  terminata 
  Kirby 
  ; 
  in 
  the 
  " 
  Explication 
  des 
  

   planches," 
  however, 
  it 
  appears 
  correctly 
  as 
  T. 
  terminata 
  

   Dej. 
  (= 
  terminalis 
  Mun. 
  Cat,), 
  an 
  African 
  species. 
  

  

  This 
  type, 
  like 
  the 
  last, 
  was 
  bought 
  by 
  Kirby 
  at 
  Mar- 
  

   sham's 
  sale, 
  and, 
  as 
  it 
  was 
  pinned 
  in 
  the 
  same 
  way, 
  he 
  

   assumed 
  — 
  probably 
  rightly^ 
  — 
  that 
  it 
  came 
  from 
  India. 
  

   I 
  have 
  seen 
  another 
  example 
  from 
  Mmishiganj 
  (Bengal) 
  

   in 
  the 
  Pusa 
  Collection, 
  and 
  Mr. 
  VitaUs 
  de 
  Salvaza 
  has 
  taken 
  

   a 
  third 
  specimen 
  at 
  Vientiane 
  in 
  Laos, 
  

  

  I 
  give 
  below 
  a 
  fresh 
  description 
  of 
  the 
  species. 
  

  

  Hexagonia 
  terminata,

  Length 
  9 
  mill. 
  Width

  Piceous, 
  basal 
  two-thirds 
  of

  epipleurae 
  of 
  elytra, 
  first 
  two 
  

   joints 
  of 
  antennae, 
  femora, 
  trochanters,

  of 
  last 
  ventral 
  

   segment 
  testaceous,

  a 
  distance 
  about 
  equal 
  to 
  their 
  diameter, 
  then 
  sharply 
  

   constricted 
  into 
  a 
  narrow 
  neck, 
  which 
  forms 
  a 
  peduncle; 
  frontal
