  Male.

  This

  From 
  the 
  fact 
  of 
  the 
  two 
  sexes 
  corresponding 
  in 
  size, 
  I 
  take 
  

   them 
  to 
  be 
  male 
  and 
  worker. 
  The 
  male 
  Bomhi 
  are 
  usually 
  con- 
  

   siderably 
  smaller 
  than 
  the 
  females.

  yellow 
  hairs 
  on 
  the 
  vertex 
  ; 
  the 
  thorax 
  clothed 
  with 
  

   ochraceous 
  pubescence, 
  as 
  well 
  as 
  the 
  two 
  basal 
  segments 
  of 
  the 
  

   abdomen 
  ; 
  the 
  wings 
  dark 
  fuscous,

  Worker. 
  — 
  Head 
  entirely 
  black, 
  as 
  broad 
  as 
  long 
  ; 
  the 
  thorax 
  

   clothed 
  wilh 
  bright 
  fulvous 
  pubescence, 
  and 
  the 
  two 
  basal 
  seg- 
  

   ments 
  of 
  the 
  abdomen 
  with 
  bright 
  golden 
  yellow 
  ; 
  the 
  rest 
  of 
  the 
  

   abdomen 
  with 
  black 
  ; 
  the 
  wings 
  dark 
  fuscous

  There 
  is 
  considerable 
  general 
  resemblance 
  between 
  this 
  species 
  

   and 
  nasulus, 
  and 
  probably 
  in 
  faded 
  specimens 
  it 
  would 
  be 
  still 
  

   greater, 
  but 
  the 
  form 
  of 
  the 
  head 
  is 
  decisive 
  of 
  their 
  difference.
