  Mr,

  Andrewes 
  on 
  the 
  

  

  front 
  tibiae 
  with 
  two 
  or 
  tliree 
  minute 
  bristles 
  on 
  outer 
  side 
  close 
  

   to 
  apex. 
  

  

  G. 
  suhaenea 
  differs 
  only 
  from 
  G. 
  subolivacea 
  in 
  being 
  

   smaller, 
  and 
  in 
  having 
  a 
  prothorax 
  a 
  little 
  longer, 
  a 
  little 
  

   narrower, 
  and 
  with 
  hind 
  angles 
  a 
  little 
  less 
  romided. 
  I 
  

   cannot 
  doubt, 
  however, 
  that 
  the 
  two 
  species 
  are 
  identical. 
  

  

  Closely 
  allied 
  to 
  G. 
  impressipennis 
  Cast., 
  thorax 
  narrower, 
  

   basal 
  foveae 
  and 
  median 
  line 
  much 
  less 
  marked; 
  elytra 
  

   rather 
  more 
  shiny, 
  striae 
  shallower, 
  third 
  interval 
  only 
  

   with 
  punctures, 
  and 
  these 
  only 
  two 
  or 
  three 
  in 
  number 
  

   towards 
  apex.

  Dioryche 
  torta. 
  Figured 
  by 
  Hope 
  (Col. 
  Man. 
  ii, 
  

   1838, 
  t. 
  2, 
  f. 
  4), 
  I 
  think 
  Macleay 
  is 
  probably 
  right 
  in 
  sup- 
  

   posing 
  that 
  Carabns 
  flavilabris 
  Fab. 
  (Suppl. 
  Ent. 
  Syst. 
  

   1798, 
  59) 
  belongs 
  to 
  this 
  or 
  an 
  allied 
  genus, 
  though 
  I 
  do 
  

   not 
  know 
  the 
  Fabrician 
  tvpe. 
  Hope 
  took 
  the 
  same 
  

   view 
  (Col. 
  Man. 
  ii, 
  1838, 
  90). 
  " 
  Motchulsky 
  (Et. 
  Ent. 
  1855, 
  

   43) 
  put 
  the 
  species 
  under 
  the 
  genus 
  Platymetopus. 
  

  

  The 
  specimen 
  of 
  D. 
  torta 
  is 
  unique 
  in 
  the 
  Museum 
  col- 
  

   lection, 
  and 
  as 
  it 
  is 
  the 
  type 
  of 
  a 
  considerable 
  genus, 
  I 
  

   have 
  described 
  it 
  in 
  some 
  detail. 
  I 
  have 
  in 
  my 
  collection 
  

   a 
  single 
  specimen, 
  also 
  from 
  Java, 
  given 
  to 
  me 
  by 
  Mr. 
  

   Sloane. 
  

  

  Dioryche

  mill. 
  Width 
  : 
  head 
  1'50, 
  

   prothorax 
  2'25, 
  elytra 
  3'00 
  mill. 
  

  

  Black, 
  shiny, 
  upper 
  surface 
  brassy, 
  labrum 
  dark 
  brown, 
  palpi 
  

   and 
  legs 
  yellow, 
  antennae 
  reddish. 
  

  

  Head 
  wide, 
  shiny, 
  finely 
  punctate, 
  clypeus 
  emarginate, 
  leaving 
  

   the 
  basal 
  membrane 
  of 
  the 
  labrum 
  exposed, 
  clypeal 
  suture 
  fairly 
  

   deep, 
  ending 
  in 
  a 
  punctiform 
  fovea, 
  from 
  which 
  a 
  fine 
  line 
  runs 
  

   obliquely 
  backwards 
  towards 
  the 
  eye; 
  eyes 
  rather 
  Hat, 
  mandibles 
  

   short 
  and 
  very 
  strong. 
  

  

  Prothorax 
  transverse, 
  not 
  very 
  convex, 
  declivous 
  to 
  front 
  angles, 
  

   rather 
  strongly 
  emarginate 
  in 
  front, 
  nearly 
  straight 
  behind, 
  widest 
  

   before 
  middle, 
  sides 
  rounded 
  in 
  front 
  then 
  quite 
  straight 
  to 
  hind 
  

   angles, 
  finely 
  bordered, 
  the 
  border 
  extending 
  a 
  little 
  way 
  from 
  

   each 
  angle 
  along 
  the 
  front 
  and 
  basal 
  margins, 
  a 
  setiferous 
  pore 
  

   at 
  a 
  third 
  from 
  apex, 
  front 
  angles 
  rather 
  sharp 
  though 
  rounded, 
  

   hind 
  angles 
  obtuse, 
  not 
  much 
  rounded; 
  surface 
  shiny, 
  finely 
  but 
  

   not 
  closely 
  punctate, 
  front 
  transverse 
  impression 
  very 
  shallow, 
  

   hind 
  one 
  rather 
  deeper, 
  median 
  line 
  fine 
  extending 
  between 
  them, 
  

   a 
  large 
  shallow 
  fovea 
  on 
  each 
  side 
  of 
  the 
  base, 
  which 
  is 
  more 
  closely 
  

   punctate 
  than 
  the 
  general 
  surface.
