  mostly

   mounted

  balsam 
  ; 
  collected 
  by

  the

  Observations. 
  — 
  This 
  species, 
  so 
  far 
  as 
  one 
  can 
  judge 
  from 
  the 
  insufficient 
  and 
  

   incomplete 
  description 
  of 
  Mayr 
  and 
  without 
  the 
  help 
  of 
  the 
  characters 
  of 
  the 
  male, 
  

   approaches 
  very 
  closely 
  B. 
  brasiliensis, 
  Mayr, 
  and 
  B. 
  bifossulata, 
  Mayr, 
  from 
  Brazil. 
  

   From 
  the 
  first, 
  however, 
  it 
  would 
  appear 
  to 
  differ 
  in 
  the 
  distinctly 
  shorter 
  terebra 
  

   (0-58-0-68 
  mm. 
  instead 
  of 
  0-80-0-84 
  mm.) 
  and 
  the 
  first 
  joint 
  of 
  the 
  fore 
  tarsus, 
  which 
  

   is 
  half 
  the 
  length 
  of 
  the 
  tibia 
  and 
  not 
  one-third 
  ; 
  from 
  the 
  second 
  species 
  in 
  the 
  

   fourth 
  joint 
  of 
  the 
  antennae, 
  which 
  is 
  twice 
  as 
  long 
  as 
  broad 
  distally 
  (instead 
  of 
  being 
  

   as 
  long 
  as 
  wide) 
  and 
  in 
  the 
  first 
  joint 
  of 
  the 
  tarsus, 
  which 
  in 
  the 
  Brazilian 
  form 
  is 
  

   scarcely 
  one-fifth 
  the 
  length 
  of 
  the 
  tibia.

  in

  balsam 
  and 
  collected 
  by 
  Prof. 
  H. 
  M. 
  Lefroy 
  in 
  India. 
  

   This 
  species 
  was 
  already 
  known 
  in 
  Java 
  and 
  Ceylon. 
  In 
  the 
  latter 
  island 
  it 
  is 
  found 
  

   in 
  the 
  receptaculi 
  of 
  Ficus 
  glomerata, 
  Roxb. 
  Mayr 
  mentions 
  having 
  examined 
  some 
  

   specimens 
  collected 
  in 
  Java 
  in 
  Ficus 
  covellii. 
  

  

  The 
  terebra 
  of 
  the 
  29 
  belonging 
  to 
  the 
  British 
  Museum 
  is 
  a 
  little 
  longer 
  than 
  the 
  

   abdomen 
  or, 
  rather, 
  somewhat 
  longer 
  (length 
  of 
  gastrum, 
  0-96 
  mm. 
  ; 
  length 
  of 
  

   projecting 
  portion 
  of 
  terebra, 
  1 
  -22 
  mm.) 
  but 
  is 
  never 
  one 
  and 
  a 
  half 
  times 
  as 
  long 
  as 
  

   the 
  abdomen.

  One 
  2 
  and 
  six 
  £$ 
  mounted 
  in 
  Canada 
  balsam 
  and 
  collected 
  by 
  H. 
  N. 
  Ridley 
  in 
  

   Singapore, 
  Malay 
  Peninsula, 
  occurring 
  in 
  Ficus 
  roxburghi. 
  This 
  species 
  was 
  known 
  

   from 
  the 
  island 
  of 
  Java, 
  where 
  it 
  is 
  found 
  in 
  the 
  receptaculi 
  of 
  Ficus 
  ribes, 
  Reinw. 
  

  

  In 
  the 
  British 
  Museum 
  specimens 
  the 
  first 
  joint 
  of 
  the 
  fore 
  tarsus 
  of 
  the 
  2 
  is 
  longer 
  

   than 
  the 
  following 
  three 
  taken 
  together 
  ; 
  in 
  the 
  <$$ 
  the 
  tibia 
  of 
  the 
  middle 
  leg 
  is 
  

   provided 
  at 
  the 
  distal 
  extremity 
  with 
  four 
  spiniform 
  teeth, 
  the 
  internal 
  one 
  of 
  which 
  

   is 
  very 
  conspicuous.
