  This 
  insect, 
  which 
  I 
  have 
  much 
  pleasure 
  in 
  dedicating 
  to 
  

   M. 
  R. 
  du 
  Buysson, 
  o£ 
  the 
  Paris 
  Museum, 
  is 
  very 
  similar 
  to 
  

   B. 
  pusillus, 
  Kohl, 
  in 
  general 
  appearance, 
  but 
  may 
  be 
  readily 
  

   distinguished 
  by 
  the 
  absence 
  of 
  yellow 
  markings 
  on 
  the 
  face 
  

   and 
  clypeus 
  and 
  the 
  totally 
  black 
  tarsi.

  The

  which 
  

   Cameron 
  says 
  that 
  /. 
  ornaticeps

  easily 
  known, 
  are 
  present 
  

   in 
  I.

  The

   no

   Tenasserim,

  I,

  described 
  from 
  Dory, 
  New 
  Guinea, 
  is 
  

   certainly 
  the

  that 
  described

  years

  P.

  the 
  type

  has 
  been 
  compared
