  than 
  broad, 
  gaping 
  at 
  the 
  apex, 
  the 
  base 
  broadly 
  rounded. 
  

   Lateral 
  hair 
  fringe 
  sparse, 
  silvery. 
  Legs 
  black 
  ; 
  the 
  apex 
  

   of 
  coxae 
  and 
  trochanters 
  ; 
  the 
  greater 
  part 
  of 
  the 
  femora 
  

   beneath 
  ; 
  and 
  the 
  tibiae 
  and 
  tarsi, 
  except 
  the 
  apices 
  of 
  the 
  

   posterior, 
  yellow. 
  

  

  The 
  $ 
  has 
  the 
  clypeus 
  slightly 
  convex 
  ; 
  the 
  apex 
  pro- 
  

   jecting 
  in 
  the 
  middle, 
  black 
  and 
  with 
  a 
  short 
  broad, 
  blunt 
  

   tooth 
  in 
  the 
  middle. 
  The 
  coloration 
  is 
  as 
  in 
  the 
  ? 
  except 
  

   that 
  the 
  fifth 
  segment 
  is 
  entirely 
  black 
  and 
  the 
  sixth 
  nearly 
  

   entirely 
  yellow. 
  Pygidial 
  area 
  of 
  equal 
  width 
  throughout 
  ; 
  

   depressed 
  before

  known 
  from 
  C.

  the 
  median 
  segment 
  

   wanting 
  yellow 
  marks 
  ; 
  by 
  there 
  being 
  only 
  a 
  central 
  basal 
  

   yellow 
  mark 
  on 
  the 
  second 
  abdominal 
  segment; 
  by 
  the 
  legs 
  

   being 
  broadly 
  black 
  at 
  the 
  base, 
  by 
  the 
  third 
  joint 
  of 
  the 
  

   flagellum 
  being 
  distinctly 
  longer 
  than 
  the 
  fourth 
  ; 
  by 
  the 
  

   central 
  lobe 
  of 
  clypeus

  roundly 
  convex 
  and 
  gaping

  It 
  is 
  probable 
  that 
  this 
  will 
  prove 
  to 
  be 
  identical 
  with 
  

   C. 
  novarce. 
  So 
  far 
  as 
  the 
  description 
  of 
  the 
  9 
  goes 
  the 
  

   only 
  difference 
  is 
  that 
  m 
  fervens 
  there 
  are 
  two 
  lines 
  on 
  the 
  

   scutellum 
  ; 
  but 
  in 
  both 
  the 
  females 
  of 
  NovarcB 
  I 
  have 
  

   examined, 
  there 
  is 
  a 
  minute 
  yellow 
  mark 
  on 
  either 
  side 
  of 
  it. 
  

   Smith's 
  description 
  of 
  the 
  $ 
  differs 
  moreover, 
  it 
  having 
  the 
  

   sixth 
  segment 
  (not 
  the 
  fifth) 
  yellow 
  marked 
  ; 
  and 
  apparently 
  

   the 
  median 
  segment 
  wants 
  the 
  yellow 
  marks. 
  

  

  Smith, 
  I 
  may 
  add, 
  named, 
  in 
  Mr. 
  Rothney's 
  collection, 
  

   the 
  $ 
  of 
  the 
  species 
  I 
  have 
  called 
  ViscJimi, 
  fervens 
  ; 
  but 
  it 
  

   does 
  not 
  agree 
  with 
  the 
  description 
  of 
  fervens 
  ; 
  and 
  my 
  

   specimen 
  is 
  certainly 
  not 
  the 
  $ 
  of 
  Novarce. 
  It 
  is 
  possible 
  

   that 
  Smith 
  has 
  assigned 
  the 
  wrong 
  $ 
  to 
  \C\s 
  fervens.
