  few 
  punctures 
  behind 
  at 
  sides, 
  extending 
  on 
  to 
  the 
  neck, 
  which 
  is 
  

   otherwise 
  smooth; 
  clypeus 
  a 
  little 
  emarginate 
  in 
  middle, 
  with 
  two 
  

   short 
  teeth 
  at 
  the 
  ends 
  of 
  the 
  emargination, 
  and 
  two 
  minute 
  

   protuberances 
  in 
  the 
  middle 
  of 
  it, 
  labrum 
  with 
  3 
  setae 
  and 
  a 
  

   median 
  tooth, 
  mandibles 
  large, 
  flat, 
  a 
  little 
  striate 
  on 
  upper 
  surface, 
  

   the 
  inner 
  carina 
  running 
  straight 
  from 
  base 
  to 
  apex; 
  eyes 
  small, 
  

   enclosed 
  behind 
  by 
  the 
  genae, 
  which 
  project 
  outwards 
  to 
  the 
  same 
  

   level 
  as 
  the 
  eye, 
  antennae 
  short, 
  almost 
  moniliform, 
  not 
  reaching 
  

   base 
  of 
  prothorax. 
  

  

  Prothorax 
  a 
  trifle 
  wider 
  than 
  head, 
  emarginate 
  in 
  front, 
  widest 
  

   just 
  behind 
  front 
  angles, 
  which 
  are 
  rather 
  sharp 
  and 
  projecting, 
  

   gradually 
  narrowed 
  to 
  hind 
  angles, 
  which 
  are 
  faintly 
  dentate 
  ; 
  sides 
  

   bordered, 
  a 
  seta 
  at 
  a 
  fifth 
  from 
  apex 
  and 
  another 
  at 
  hind 
  angle, 
  

   basal 
  margin 
  bordered; 
  front 
  transverse 
  impression 
  deep, 
  rather 
  

   distant 
  from 
  margin, 
  median 
  line 
  well 
  marked, 
  not 
  reaching 
  extremi- 
  

   ties, 
  but 
  joining 
  the 
  front 
  impression; 
  surface 
  smooth, 
  base 
  finely 
  

   rugose. 
  

  

  Elytra 
  as 
  wide 
  as 
  prothorax, 
  parallel, 
  dentate 
  at 
  shoulder, 
  striae 
  

   well 
  marked, 
  crenulate, 
  no 
  scutellary 
  striole, 
  intervals 
  smooth, 
  

   3 
  with 
  a 
  large 
  setiferous 
  puncture 
  at 
  two-thirds 
  from 
  base 
  and 
  

   another 
  close 
  to 
  apex, 
  8 
  and 
  base 
  finely 
  and 
  densely 
  aciculate, 
  

   marginal 
  row 
  of 
  punctures 
  close 
  and 
  uninterrupted. 
  

  

  Underside, 
  except 
  along 
  median 
  line, 
  finely 
  and 
  densely 
  punctate; 
  

   paragenae 
  both 
  emarginate 
  and 
  dentate, 
  prosternal 
  process 
  not 
  

   bordered, 
  metepisterna 
  elongate, 
  two 
  setae 
  on 
  each 
  side 
  of 
  last 
  

   ventral 
  segment; 
  front 
  tibiae 
  with 
  two 
  extra 
  denticulations, 
  

   intermediate 
  tibiae 
  with 
  a 
  strong 
  spur 
  near 
  apex. 
  

  

  Macleay's 
  insect 
  is 
  evidently 
  related 
  to 
  Chaudoir's 
  

   D. 
  dicaelus, 
  of 
  which 
  I 
  have 
  not 
  seen 
  an 
  example. 
  The 
  

   latter, 
  however, 
  is 
  smaller, 
  has 
  a 
  sharp 
  prominent 
  tooth 
  

   at 
  the 
  hind 
  angle 
  of 
  the 
  prothorax, 
  which 
  is 
  finely 
  punc- 
  

   tured 
  mstead 
  of 
  smooth, 
  while 
  the 
  sides 
  of 
  the 
  base 
  are 
  

   apparently 
  punctured 
  instead 
  of 
  rugose.

  Mochtherus 
  (Dromlus) 
  tetraspilotus. 
  Macleay 
  per- 
  

   ceived 
  that 
  his 
  insect 
  did 
  not 
  accord 
  very 
  well 
  with 
  the 
  

   genus 
  Dromius. 
  He 
  thought 
  it 
  allied 
  to 
  Cambus 
  noiulalus 
  

   F. 
  (Syst. 
  Eleuth. 
  i, 
  1801, 
  201), 
  a 
  species 
  now 
  to 
  be 
  included 
  

   m 
  the 
  genus 
  Craspedophorus, 
  and 
  therefore 
  far 
  removed 
  

   from 
  Dromius. 
  The 
  genus 
  Mochtherus 
  is 
  due 
  to 
  Schmidt- 
  

   Goebel 
  (Faun. 
  Col. 
  Birm. 
  1840, 
  76), 
  and 
  it 
  is 
  dealt 
  with 
  

   both 
  by 
  Bates 
  (Ent. 
  Month. 
  Mag. 
  vi, 
  1869, 
  71), 
  and 
  by 
  

   Chaudoir 
  in 
  his 
  " 
  Memoire 
  sur 
  les 
  Coptoderides 
  " 
  (Ann 
  

   Soc. 
  Ent. 
  Belg. 
  xii, 
  1869, 
  240). 
  The 
  species 
  is 
  widely
