  Metepistema 
  without 
  furrow 
  near 
  outer 
  margin; 
  prostemal 
  

   process 
  faintly 
  margined 
  ; 
  underside 
  punctate, 
  rather 
  closely 
  

   along 
  the 
  sides 
  of 
  the 
  ventral 
  surface, 
  more 
  sparsely 
  along 
  its 
  median 
  

   line, 
  on 
  the 
  prostemal 
  process 
  and 
  the 
  pro- 
  and 
  meso-episterna. 
  

   Front 
  femora 
  without 
  tooth; 
  dilated 
  joints 
  of 
  tarsi 
  a 
  little 
  longer 
  

   than 
  wide, 
  joint 
  1 
  elongate-triangular, 
  2 
  and 
  3 
  rectangular

   contracted 
  at 
  base. 
  

  

  Surface 
  of 
  tlie 
  body 
  pubescent 
  (type 
  much 
  rubbed), 
  the 
  pubescence 
  

   bemg 
  much 
  closer 
  on 
  the 
  elytra 
  than 
  on 
  the 
  head 
  and 
  thorax. 
  

   Prostemal 
  process 
  glabrous 
  between

  a 
  tuft 
  of 
  

   erect 
  hairs 
  at 
  the 
  apex. 
  

  

  Closely 
  allied 
  to 
  C.

  but 
  less 
  elongate, 
  

   with 
  side 
  margins 
  of

  more 
  distinctly 
  sinuate 
  before 
  

   hind

  head 
  and

  more,

  4. 
  Pheropsophus 
  (Brachinus) 
  tripustulatus 
  (Ent. 
  Syst. 
  i, 
  

   1792, 
  145). 
  Bygone 
  generations 
  of 
  Entomologists 
  have 
  

   been 
  much 
  exercised 
  over 
  this 
  species. 
  The 
  trouble 
  was 
  

   originated 
  by 
  Westermann, 
  who 
  sent 
  a 
  Javanese 
  insect 
  

   to 
  Dejean 
  as 
  " 
  the 
  veritable 
  Brachinus 
  trijmslulatus 
  of 
  

   Fabricius." 
  Actually 
  it 
  was 
  nothing 
  of 
  the 
  kind, 
  and 
  

   Dejean, 
  in 
  describing 
  it 
  under 
  the 
  name 
  of 
  Helhw 
  tripustu- 
  

   latus 
  (Spec. 
  Gen. 
  i, 
  1825, 
  286), 
  indicates 
  his 
  scepticism 
  

   sufficiently 
  clearly. 
  Hope 
  (Col. 
  Man. 
  ii, 
  1838, 
  101) 
  re- 
  

   marks 
  : 
  " 
  The 
  specimens 
  " 
  [there 
  seems 
  to 
  be 
  only 
  one] 
  

   " 
  in 
  the 
  Banksian 
  Cabinet 
  are 
  decidedly 
  of 
  the 
  genus 
  

   Pheropsophus." 
  Motchulsky 
  (Et. 
  Ent. 
  1855, 
  55) 
  says 
  : 
  

   " 
  D'apres 
  la 
  Col. 
  de 
  Banks 
  cette 
  espece 
  est 
  voisine 
  du 
  

   Br. 
  marginalis 
  Schonh., 
  mais 
  non 
  un 
  Macrocheilus, 
  ainsi 
  

   que 
  c'est 
  le 
  cas 
  pour 
  I'exemplaire 
  conserve 
  dans 
  la 
  Col. 
  

   de 
  Copenhague." 
  I 
  gather 
  from 
  this 
  that 
  both 
  he 
  and 
  

   Hope 
  saw 
  the 
  type 
  in 
  the 
  Banks 
  Collection; 
  also 
  that 
  in 
  

   the 
  Copenhagen 
  Collection 
  a 
  Macrochilus 
  figures 
  as 
  the 
  

   Fabrician 
  insect. 
  No 
  further 
  effort 
  seems 
  to 
  have 
  been 
  

   made 
  to 
  elucidate 
  the 
  matter, 
  and 
  among 
  the 
  specimens 
  

   in 
  the 
  Banks 
  Collection 
  I 
  found, 
  indicated 
  as 
  "type? 
  ", 
  

   three 
  examples 
  of 
  the 
  species 
  at 
  present 
  known 
  as 
  Macro- 
  

   chilus 
  bensoni 
  Hope 
  (but 
  see 
  under 
  Olivier), 
  the 
  continental 
  

   representative 
  of 
  Dejean's 
  Macrochilus 
  {Helluo) 
  tripustu- 
  

   latus. 
  On 
  one 
  of 
  these 
  examples 
  is 
  a 
  note 
  by 
  the 
  late 
  

   C. 
  0. 
  Waterhouse 
  dated 
  2. 
  x. 
  1883 
  : 
  " 
  These 
  specimens 
  

   were 
  found 
  in 
  the 
  Supplementary 
  drawer 
  at 
  end 
  of 
  Banks 
  

   Coll. 
  with 
  no 
  label." 
  The 
  description, 
  however, 
  left 
  little
