   Long.

  milliin. 
  

  

  In 
  colour 
  this 
  species 
  agrees 
  with 
  politus, 
  Schmidt, 
  and 
  it 
  

   is 
  pilous 
  in 
  the 
  same 
  way, 
  but 
  the 
  presternum 
  is 
  on 
  a 
  different 
  

   plan. 
  In 
  Sedilloti 
  the 
  presternum 
  between 
  the 
  strite 
  is 
  on 
  one 
  

   plane, 
  the 
  surface 
  is 
  sculptured 
  with 
  large 
  shallow 
  punctures 
  

   closely 
  set 
  together 
  and 
  more 
  or 
  less 
  rugose 
  anteriorly, 
  the 
  

   rugosity 
  being 
  most 
  apparent 
  on 
  the 
  lobe 
  ; 
  and 
  the 
  base, 
  as 
  

   in 
  pluristriatus, 
  Fairm., 
  is 
  narrowly 
  smooth. 
  The 
  prosternal 
  

   stria? 
  are 
  one 
  third 
  wider 
  apart 
  than 
  in 
  pluristriatus, 
  and 
  they 
  

   diverge 
  slightly 
  in 
  front 
  of 
  the 
  coxa3. 
  

  

  In 
  many 
  species 
  of 
  this 
  genus 
  the 
  presternum 
  has 
  a 
  trans- 
  

   verse 
  bulge 
  or 
  ridge 
  across 
  the 
  centre 
  of 
  the 
  keel 
  ; 
  it 
  may 
  be 
  

   observed 
  well 
  in 
  S. 
  cancer, 
  Bedeli, 
  punctulatus, 
  and 
  pluri- 
  

   striatus. 
  But 
  in 
  the 
  hispanicus 
  and 
  arachnoides 
  group 
  there 
  

   is 
  a 
  transverse 
  sulcus 
  which 
  divides 
  the 
  main 
  part 
  of 
  the 
  pre- 
  

   sternum 
  from 
  the 
  lobe. 
  In 
  these 
  last 
  species 
  the 
  lobe 
  is 
  said 
  

   to 
  be 
  reflexed. 
  Monsieur 
  Sedillot, 
  whose 
  labours 
  in 
  connexion 
  

   with 
  the 
  Mediterranean 
  fauna 
  are 
  well 
  known, 
  captured 
  this 
  

   species 
  at 
  Kef 
  Kourrat, 
  in 
  the 
  Province 
  of 
  Constantine, 
  in 
  

   1886. 
  

  

  Saprinus 
  aterrimus, 
  Erichson. 
  

  

  A 
  long 
  series 
  of 
  this 
  insect, 
  recently 
  brought 
  from 
  S. 
  Cathe- 
  

   rine, 
  shows 
  that 
  the 
  species 
  possesses 
  somewhat 
  similar 
  sexual 
  

   characters 
  to 
  those 
  in 
  Saprinus 
  ceneicollis, 
  Mars., 
  and 
  cceso- 
  

   pygvs, 
  Mars. 
  The 
  female 
  has 
  a 
  very 
  deep 
  sulcus 
  in 
  the 
  apex 
  

   of 
  the 
  pygidium, 
  formed 
  like 
  a 
  widened-out 
  V, 
  and 
  the 
  inter- 
  

   median 
  angle 
  is 
  prominent. 
  

  

  Teretrius 
  basalis, 
  n. 
  sp. 
  

  

  Cylindricus, 
  subelongatus, 
  subrufus, 
  nitidus, 
  undique 
  punctulatus 
  

   et 
  minutissime 
  strigosus 
  ; 
  fronte 
  parum 
  convexa, 
  haud 
  striata 
  ; 
  

   pronoto 
  stria 
  integra 
  ; 
  elytris 
  transversim 
  basi 
  rufo-marginatis 
  ; 
  

   prosterno 
  basi 
  impresso 
  striis 
  obscuris 
  divaricatis, 
  lobo 
  antice 
  

   marginato 
  ; 
  mesosterno 
  marginatoj 
  parum 
  acute 
  producto 
  ; 
  tibiis 
  

   anticis 
  7-dentatis. 
  

  

  Long. 
  2| 
  millim. 
  

  

  This 
  species 
  is 
  about 
  the 
  size 
  of 
  picipes, 
  F., 
  but 
  rather 
  

   more 
  cylindrical. 
  The 
  elytra 
  are 
  without 
  the 
  smooth 
  bases 
  

   so 
  commonly 
  seen 
  in 
  the 
  genus, 
  but 
  immediately 
  behind 
  such
