   The 
  three 
  or 
  four 
  basal 
  joints 
  of 
  the 
  antenna? 
  are 
  blackish, 
  the 
  

   others 
  red, 
  the 
  penultimate 
  joints 
  strongly 
  transverse. 
  The 
  

   head 
  and 
  thorax 
  are 
  deep 
  black, 
  dull, 
  closely 
  and 
  somewhat 
  

   coarsely 
  punctate, 
  and 
  bear 
  a 
  black 
  pubescence 
  ; 
  a 
  narrow, 
  

   indistinct,

  short 
  smooth 
  line 
  in 
  front 
  of 
  the

  a

  the 
  

   terminal

  a

  This 
  is 
  very 
  closely 
  allied 
  to 
  the 
  European 
  S. 
  erythro- 
  

   pteruSj 
  but 
  differs 
  as 
  follows 
  : 
  — 
  The 
  stature 
  is 
  considerably 
  

   larger, 
  the 
  antennae 
  are 
  larger, 
  with 
  notably 
  longer 
  third 
  

   joint, 
  the 
  thorax 
  is 
  broader, 
  and 
  the 
  basal 
  abdominal 
  segment 
  

   is 
  spotted 
  with 
  yellow 
  on 
  each 
  side. 
  Thus, 
  close 
  as 
  this 
  

   species 
  is 
  to 
  the 
  European 
  S. 
  ccesareus 
  and 
  erythropterus, 
  it 
  

   differs 
  decidedly 
  from 
  either.

  This 
  is 
  an 
  interesting 
  genus, 
  intermediate 
  between

   Philonthus

  the 
  Eucibdelus 
  groups 
  of 
  genera,

  of

  group. 
  The 
  two 
  

   lobes 
  of

  division 
  

   between
