  variable, 
  but 
  after 
  comparing 
  Macleay's 
  type 
  with 
  Wiede- 
  

   mann's 
  description, 
  and 
  examining 
  a 
  number 
  of 
  specimens 
  

   from 
  different 
  localities, 
  I 
  think 
  the 
  species 
  are 
  distinct, 
  

   and 
  for 
  Macleay's 
  I 
  propose 
  the 
  new 
  name 
  of 
  0. 
  macleayi. 
  

   To 
  settle 
  the 
  matter 
  beyond 
  doubt, 
  it 
  will 
  be 
  necessary 
  to 
  

   wait 
  till 
  Wiedemann's 
  type 
  is 
  available 
  for 
  examination. 
  

   Macleay's 
  species 
  seems 
  to 
  be 
  confined 
  to 
  Java. 
  Wiede- 
  

   mann's 
  is 
  recorded 
  also 
  from 
  Burma, 
  Indo-China, 
  and 
  the 
  

   Philippine 
  Is. 
  

  

  Orthogonius 
  macleayi. 
  Length 
  18 
  mill. 
  Width 
  : 
  head 
  

   3'25, 
  prothorax 
  4*5,

  Dark 
  brown, 
  ventral 
  surface 
  and 
  mouth-parts 
  a 
  little 
  lighter. 
  

   Head 
  wide, 
  intricately 
  wrinkled, 
  more 
  Ughtly 
  behind 
  and 
  more 
  

   deeply 
  in 
  front, 
  a 
  small 
  smooth 
  space 
  in 
  the 
  middle 
  of 
  front, 
  just 
  

   behind 
  which 
  are 
  two 
  short 
  impressed 
  longitudinal 
  lines 
  (possibly 
  

   individual), 
  frontal 
  impressions 
  rather 
  concealed 
  by 
  the 
  strigose 
  

   surface, 
  clypeus 
  truncate 
  in 
  front, 
  its 
  surface 
  raised 
  in 
  the 
  middle 
  

   behind, 
  suture 
  deep; 
  labrmn 
  porrect, 
  6-setose, 
  a 
  Uttle 
  raised 
  at 
  

   side 
  margins; 
  eyes 
  projecting, 
  two 
  supra-orbital 
  setae; 
  antennae 
  

   short, 
  stout, 
  just 
  reaching

  of 
  prothorax; 
  ligula 
  bisetose 
  at 
  

   apex. 
  

  

  Prothorax 
  slightly 
  convex, 
  much 
  wider 
  than

  and 
  at 
  base, 
  

   explanate 
  at 
  sides, 
  more 
  widely 
  behind, 
  sides 
  rounded, 
  more 
  so 
  in 
  

   front 
  than 
  behind, 
  so 
  that 
  the 
  front 
  angles 
  have 
  disappeared, 
  but 
  

   the 
  hind 
  angles 
  are 
  merely 
  obtuse 
  and 
  rounded; 
  front 
  transverse 
  

   impression 
  weakly, 
  hind 
  one 
  strongly 
  marked, 
  median 
  line 
  faint, 
  

   basal 
  foveae

  surface 
  rather 
  finely 
  transversely 
  wrinkled, 
  

   more 
  coarsely 
  along 
  base, 
  longitudinally 
  strigose 
  along 
  the 
  front 
  

   transverse 
  impression, 
  explanate 
  side 
  margin 
  uneven. 
  

  

  Elytra 
  parallel, 
  square 
  at 
  shoulder, 
  a 
  deep 
  impression 
  on 
  each 
  side 
  

   in 
  front 
  of 
  base 
  of 
  stria 
  4, 
  margin 
  rounded 
  at 
  apex, 
  punctate-striate, 
  

   a 
  scutellary 
  striole 
  between 
  1 
  and 
  2, 
  joining 
  1 
  behind 
  ; 
  odd 
  intervals 
  

   much 
  wider 
  than 
  even 
  ones, 
  2 
  with 
  a 
  single 
  row 
  of 
  punctures 
  reach- 
  

   ing 
  middle, 
  4 
  irregularly 
  but 
  thinly 
  punctured 
  up 
  to 
  two-thirds 
  from 
  

   base, 
  6 
  more 
  closely 
  punctured 
  (roughly 
  in 
  two 
  rows) 
  up 
  to 
  three- 
  

   quarters, 
  8 
  with 
  an 
  irregular 
  row 
  stopping 
  at 
  two-thirds, 
  3 
  with 
  

   two 
  large 
  setiferous 
  punctures 
  near 
  apex 
  adjoining 
  stria 
  2, 
  5 
  with 
  

   two 
  or 
  three 
  large 
  setiferous 
  punctures 
  near 
  base, 
  7 
  — 
  which 
  is 
  very 
  

   narrow 
  — 
  with 
  a 
  row 
  of 
  about 
  twelve 
  setiferous 
  punctures 
  extending 
  

   along 
  its 
  entire 
  length 
  (the 
  setae 
  on 
  these 
  are 
  very 
  conspicuous), 
  

   9 
  with 
  an 
  uninterrupted 
  row 
  of 
  large 
  pmictures, 
  some 
  of 
  which 
  

   certainly 
  have 
  small 
  setae.
