  Underside 
  smooth,

  metepistema 
  

   smooth, 
  elongate, 
  ventral 
  surface 
  with 
  a 
  small 
  callosity 
  on 
  each 
  side 
  

   of

  Compared 
  with 
  Macleay's 
  type, 
  the 
  examples 
  of 
  0. 
  alter- 
  

   nans 
  Wied. 
  which 
  I 
  have 
  seen 
  are 
  darker 
  and 
  more 
  elongate, 
  

   the 
  hind 
  angles 
  of 
  the 
  prothorax 
  more 
  romided, 
  the 
  even 
  

   intervals 
  of 
  the 
  elytra 
  — 
  especially 
  6 
  — 
  more 
  finely 
  and 
  

   much 
  more 
  closely 
  punctured, 
  7 
  with 
  only 
  half 
  a 
  dozen 
  

   setiferous 
  punctures. 
  

  

  39. 
  Drypta 
  lineola. 
  Named 
  by 
  Dejean, 
  this 
  species 
  is 
  

   here 
  described 
  for 
  the 
  first 
  time 
  by 
  Macleay. 
  Dejean 
  

   described 
  it 
  subsequently 
  (Spec. 
  Gen. 
  i, 
  1825, 
  184) 
  and 
  the 
  

   name 
  has 
  hitherto 
  been 
  ascribed 
  erroneously 
  to 
  him. 
  It 
  

   is 
  a 
  common 
  species 
  and 
  often 
  referred 
  to 
  in 
  entomological 
  

   literature 
  ; 
  it 
  varies 
  a 
  good 
  deal 
  and 
  several 
  local 
  forms 
  

   have 
  been 
  described, 
  among 
  which 
  I 
  may 
  mention 
  D. 
  virgata 
  

   Chaud. 
  (Bull. 
  Mosc. 
  1850, 
  i, 
  34), 
  which 
  extends 
  over 
  Burma, 
  

   S. 
  China, 
  and 
  Indo-China, 
  and 
  D. 
  philippinensis 
  Chaud. 
  

   (Bull. 
  Mosc. 
  1877, 
  ii, 
  262) 
  from 
  the 
  Philippine 
  Is. 
  Bates' 
  

   D. 
  japonica 
  (Trans. 
  Ent. 
  Soc. 
  1873, 
  303) 
  is 
  closely 
  allied, 
  

   but 
  seems 
  a 
  fairly 
  distinct 
  species. 
  Following 
  Macleay's 
  

   description 
  is 
  an 
  " 
  Observation," 
  in 
  the 
  course 
  of 
  which 
  

   he 
  indicates 
  an 
  Australian 
  species 
  under 
  the 
  name 
  of 
  

   D. 
  australis 
  ; 
  this 
  may, 
  perhaps, 
  also 
  rank 
  as 
  distinct. 
  

   In 
  its 
  various 
  forms 
  the 
  species 
  is 
  spread 
  all 
  over 
  S.E. 
  Asia 
  

   and 
  the 
  Malay 
  region. 
  

  

  40. 
  Desera 
  (Drypta) 
  unidentata. 
  Described 
  later 
  on 
  by 
  

   Klug 
  (Jahrb. 
  1834, 
  53) 
  under 
  the 
  name 
  of 
  D. 
  coelestma. 
  

   Both 
  descriptions 
  are 
  so 
  inadequate 
  that 
  I 
  give 
  a 
  more 
  

   detailed 
  one. 
  The 
  species 
  is 
  apparently 
  confined 
  to 
  Java.
