  it 
  is 
  reddish 
  ; 
  but 
  in 
  other 
  respects 
  the 
  two 
  agree, 
  except 
  

   that 
  the 
  hinder 
  femora 
  have 
  more 
  black. 
  It 
  may, 
  how- 
  

   ever, 
  be 
  as 
  well 
  to 
  give 
  a 
  description 
  of 
  the 
  2 
  M. 
  opulcnta 
  

   in 
  case 
  M. 
  soror 
  may 
  be 
  different. 
  

  

  Head 
  as 
  wide 
  as 
  the 
  thorax; 
  red, 
  coarsely 
  and 
  rugosely 
  

   punctured, 
  shining, 
  bare, 
  behind 
  the 
  eyes 
  the 
  vertex 
  

   almost 
  as 
  long 
  as 
  the 
  width 
  of 
  the 
  eyes. 
  Scape 
  of 
  the 
  

   antenna; 
  rufous, 
  darker 
  at 
  the 
  apex 
  and 
  beneath, 
  and 
  

   bearing 
  large 
  punctures 
  ; 
  the 
  flagellum 
  black, 
  thickly 
  

   covered 
  with 
  fuscous 
  pile. 
  Thorax 
  black, 
  twice 
  the 
  length 
  

   of 
  the 
  head; 
  the 
  sides 
  almost 
  parallel, 
  not 
  dilated 
  towards 
  

   the 
  apex, 
  very 
  coarsely 
  rugosely 
  punctured 
  ; 
  the 
  apex 
  of 
  

   the 
  median 
  segment 
  with 
  a 
  very 
  slight 
  oblique 
  slope 
  ; 
  

   above 
  coarsely 
  punctured, 
  the 
  rest 
  finely 
  and 
  uniformly 
  

   rugose 
  ; 
  the 
  lower 
  part 
  covered 
  with 
  long 
  golden 
  hairs. 
  

   The 
  pleurai 
  smooth 
  ; 
  the 
  base 
  of 
  the 
  pronotum 
  and 
  the 
  

   metapleura;

  punctured; 
  the 
  lower 
  portion 
  of

   metapleurai 
  thickly 
  covered 
  with 
  pale 
  golden 
  pubescence. 
  

   Petiole 
  black, 
  the 
  apex 
  (probably 
  the 
  whole 
  in 
  fresh 
  

   examples) 
  fringed 
  with 
  golden 
  hairs; 
  on 
  the 
  base 
  of 
  the 
  

   second 
  segment 
  are 
  two 
  large 
  oval 
  golden 
  marks 
  ; 
  its 
  apex 
  

   has 
  a 
  golden 
  band, 
  broadly 
  narrowed 
  in 
  the 
  centre 
  ; 
  the 
  

   third 
  segment 
  is 
  entirely 
  golden 
  ; 
  the 
  pygidium 
  coriaceous, 
  

   fringed 
  at 
  the 
  sides 
  with 
  long 
  golden 
  hairs. 
  The 
  second 
  

   ventral 
  segment 
  has 
  large, 
  somewhat 
  shallow, 
  clearly 
  

   separated 
  punctures 
  ; 
  all 
  the 
  segments 
  fringed 
  with 
  long 
  

   golden 
  hairs. 
  The 
  front 
  four 
  legs 
  red, 
  the 
  knees 
  black, 
  

   sparsely 
  covered 
  with 
  golden 
  hairs, 
  especially 
  the 
  tarsi 
  ; 
  

   the 
  apical 
  three-fourths 
  of 
  the 
  hind 
  femora 
  are 
  black 
  ; 
  the 
  

   tibise 
  and 
  tarsi 
  thickly 
  covered

  The 
  form 
  of 
  the 
  spots 
  on 
  the 
  second 
  abdominal 
  seg- 
  

   ment 
  varies. 
  In 
  one 
  example 
  on 
  the 
  inner 
  side 
  at 
  the 
  apex 
  

   they 
  are 
  rounded 
  ; 
  in 
  another 
  they 
  are 
  there 
  truncated 
  as 
  

   figured 
  by 
  Saussure 
  in 
  his 
  M. 
  liuuibcrtiana; 
  in 
  another 
  

   they 
  are 
  more 
  as 
  he 
  figures 
  them 
  in 
  .V. 
  soror, 
  but
