  Oval, 
  convex, 
  black, 
  and 
  sliinlug- 
  ; 
  tlie 
  head, 
  stria 
  nearly 
  

   straight 
  anteriorly, 
  surface 
  and 
  also 
  the 
  mandibles 
  rather 
  

   closely 
  punttulate, 
  behind 
  the 
  stria 
  are 
  two 
  feeble 
  impres- 
  

   sions 
  ; 
  the 
  thorax 
  is 
  very 
  feebly 
  punctulate, 
  with 
  two 
  lateral 
  

   striai, 
  the 
  external 
  anteriorly 
  passes 
  the 
  angle, 
  internal 
  is 
  

   crenulate 
  behind 
  the 
  head 
  and 
  not 
  interrupted 
  ; 
  the 
  elytra, 
  

   striro, 
  there 
  is 
  no 
  subhumeral, 
  1-3 
  dorsiil 
  are 
  complete, 
  the 
  

   first 
  turns 
  towards 
  the 
  second 
  at 
  the 
  base, 
  and 
  the 
  interstice 
  

   between 
  the 
  second 
  and 
  third 
  widens 
  out 
  anteriorly; 
  the 
  

   pygidia 
  are 
  somewhat 
  closely 
  punctate, 
  and 
  some 
  of 
  the 
  

   punctures 
  are 
  ocellate, 
  especially 
  on 
  the 
  outer 
  parts 
  ; 
  the 
  

   inesosternum 
  is 
  sinuous 
  and 
  markedly 
  rnarginate, 
  the 
  marginal 
  

   stria 
  laterally 
  does 
  not 
  quite 
  reach 
  the 
  metasternal 
  suture; 
  

   the 
  anterior 
  tibiaj 
  are 
  5-dentate, 
  the 
  two 
  apical 
  teeth 
  are 
  close 
  

   together 
  and 
  have 
  a 
  common 
  base. 
  

  

  This 
  is 
  only 
  the 
  fourth 
  species 
  of 
  Hister 
  recorded 
  from 
  

   Madagascar; 
  Hister 
  goadoti 
  and 
  a'quislrius, 
  Mars., 
  are 
  now 
  

   assigned 
  to 
  Atholus.

  The 
  tibiai 
  of 
  this 
  species 
  are 
  similar 
  to 
  many 
  Trypancei, 
  but 
  

   Mr. 
  Arrow 
  informs 
  me 
  that 
  some 
  of 
  the 
  Lamellicornes, 
  such 
  

   as 
  Parastasia 
  and 
  its 
  allies, 
  also 
  liave 
  similar 
  tibiae; 
  so 
  this 
  

   stiuclure 
  need 
  not 
  disturb 
  my 
  systematic 
  arrangement 
  of 
  the 
  

   Histeridse 
  in 
  placing 
  it 
  in 
  the 
  section 
  with 
  emarginate 
  or 
  

   sinuous 
  mesostcrna.
