  tion 
  ; 
  the 
  front 
  and 
  vertex 
  sparsely 
  covered 
  with 
  longish 
  

   blackish 
  hair 
  ; 
  the 
  cheeks, 
  face, 
  and 
  clypeus 
  densely 
  covered 
  

   with 
  silvery 
  pile 
  and 
  with 
  longish 
  fuscous 
  hair. 
  Eyes 
  

   slightly 
  converging 
  beneath 
  ; 
  the 
  ocelli 
  hardly 
  forming 
  a 
  

   triangle 
  ; 
  a 
  furrow 
  along 
  their 
  side, 
  the 
  furrows 
  meeting 
  

   into 
  a 
  V-shaped 
  depression, 
  which 
  has 
  a 
  sharp 
  raised 
  pro- 
  

   jection 
  in 
  its 
  centre. 
  Clypeus 
  broadly 
  rounded, 
  the 
  apex 
  

   depressed 
  and 
  with 
  a 
  short 
  incision 
  in 
  the 
  centre. 
  Thorax 
  

   sparsely 
  covered 
  with 
  a 
  fuscous 
  to 
  black 
  pubescence 
  ; 
  the 
  

   pubescence 
  on 
  the 
  middle 
  segment 
  dull 
  fulvous. 
  Pro- 
  

   notum 
  with 
  a 
  distinct 
  and 
  broad 
  depression 
  in 
  its 
  centre 
  ; 
  

   the 
  mesothorax 
  is 
  also 
  slightly 
  depressed 
  in 
  the 
  centre, 
  

   and 
  the 
  scutellum 
  and 
  post 
  scutellum 
  are 
  distinctly 
  

   and 
  broadly 
  furrowed. 
  Median 
  segment 
  transversely 
  and 
  

   regularly 
  striolated 
  ; 
  a 
  wide 
  and 
  deep 
  furrow 
  in 
  its 
  centre 
  

   at 
  the 
  apex, 
  and 
  there 
  is 
  an 
  elongated 
  pear-shaped 
  depres- 
  

   sion 
  on 
  the 
  upper 
  part. 
  Abdomen 
  shining, 
  with 
  a 
  plum- 
  

   beous 
  tint 
  ; 
  the 
  petiole 
  covered 
  with 
  long 
  black 
  hair, 
  and 
  a 
  

   little 
  longer 
  than 
  the 
  coxae 
  ; 
  the 
  pygidial 
  area 
  shagreened, 
  

   and 
  with 
  a 
  few 
  scattered 
  punctures. 
  Legs 
  with 
  the 
  coxae, 
  

   trochanters 
  and 
  four 
  apical 
  joints 
  of 
  the 
  tarsi 
  and 
  the 
  spines 
  

   on 
  the 
  hinder 
  tibiae, 
  blackish. 
  

  

  In 
  the 
  colour 
  of 
  the 
  body 
  and 
  pubescence 
  this 
  species 
  

   comes 
  nearest 
  to 
  8. 
  rufipennis, 
  but 
  is 
  readily 
  known 
  from 
  it 
  

   by 
  the 
  reddish 
  legs. 
  It 
  can 
  hardly, 
  I 
  think, 
  be 
  an 
  extreme 
  

   variety 
  of 
  8. 
  auriilenta, 
  from 
  which, 
  apart 
  from 
  the 
  dif- 
  

   ference 
  in 
  coloration 
  of 
  the 
  head 
  and 
  thorax 
  and 
  their 
  

   pubescence 
  (comparing 
  the 
  females), 
  it 
  differs 
  in 
  having 
  

   the 
  pronotum 
  more 
  distinctly 
  raised 
  above 
  and 
  separated 
  

   from 
  the 
  mesonotum, 
  besides 
  being 
  broadly 
  furrowed 
  in 
  the 
  

   centre 
  ; 
  the 
  mesonotum 
  and 
  scutellums 
  are 
  also 
  broadly 
  

   furrowed, 
  and 
  the 
  median 
  segment, 
  instead 
  of 
  having 
  three 
  or 
  

   four 
  raised 
  ridges, 
  is 
  uniformly 
  and 
  regularly 
  striolated. 
  

  

  The 
  amount 
  of 
  black 
  on 
  the 
  tarsi 
  varies, 
  as 
  does 
  also 
  

   the 
  colour 
  of 
  the 
  spines 
  and 
  wings, 
  the 
  latter 
  in 
  one 
  specimen
