  Hister 
  sulcipygus 
  should 
  be 
  placed 
  in 
  the 
  list 
  next 
  to 
  

   ignavus, 
  Fahr., 
  as 
  it 
  agrees 
  with 
  it 
  in 
  several 
  characters, 
  such 
  

   as 
  the 
  subhumeral 
  stria, 
  general 
  contour, 
  and 
  punctuation. 
  

   The 
  differences 
  are 
  that 
  the 
  epistoraa 
  is 
  round 
  and 
  marginate 
  

   anteriorly, 
  mandibles 
  marginate, 
  frontal 
  stria 
  elevated, 
  and 
  

   the 
  thoracic 
  strise 
  are 
  but 
  two 
  in 
  number. 
  The 
  propygidium 
  

   is 
  wholly 
  punctured, 
  and 
  the 
  two 
  sulci 
  on 
  the 
  outer 
  margin 
  of 
  

   the 
  pygidium 
  are 
  deep, 
  somewhat 
  oval, 
  and 
  unlike 
  anything 
  

   yet 
  seen 
  in 
  the 
  genus 
  Ulster.

  I 
  am 
  much 
  indebted 
  to 
  Mr. 
  H. 
  W. 
  Bates 
  for 
  a 
  specimen 
  of 
  

   this 
  singular 
  insect.

  Macrosternus 
  circularise 
  Mars., 
  has 
  a 
  similar 
  outline 
  and 
  

   convexity 
  to 
  this 
  species, 
  and 
  I 
  have 
  adopted 
  the 
  same 
  trivial 
  

   name 
  for 
  it. 
  At 
  present 
  the 
  species, 
  although 
  it 
  is 
  very 
  dis- 
  

   similar 
  to 
  any 
  hitherto 
  described 
  except 
  H. 
  circulus, 
  Schmidt, 
  

   the 
  description 
  of 
  which 
  is 
  in 
  the 
  press, 
  may 
  be 
  placed 
  in 
  the 
  

   same 
  group 
  as 
  (equatorius, 
  Mars. 
  The 
  prosternum 
  is 
  divided 
  

   into 
  two 
  nearly 
  equal 
  parts 
  by 
  a 
  transverse 
  line 
  ; 
  the 
  anterior 
  

   lobe 
  is 
  punctured 
  and 
  has 
  three 
  well-marked 
  striae 
  on 
  each 
  

   side. 
  The 
  anterior 
  outline 
  of 
  the 
  mesosternum 
  is 
  feebly 
  bow- 
  

   shaped.

   my 
  own 
  cabinet.
