  coloration, 
  but 
  is 
  much 
  smaller 
  and 
  more 
  slenderly 
  built; 
  

   may 
  readily 
  be 
  known 
  by 
  the 
  central 
  tooth 
  on 
  the 
  median 
  

   segment 
  not 
  being 
  broad 
  and 
  plate-like.

  Hab. 
  Barrackpore 
  (RotJiney). 
  

  

  This 
  species 
  fits 
  best 
  into 
  Bingham's 
  "Section 
  D" 
  ; 
  but 
  

   the 
  head 
  has 
  less 
  black 
  and 
  more 
  red 
  than 
  in 
  most 
  of 
  the 
  

   species 
  of 
  the 
  group. 
  The 
  spined 
  metanotum, 
  size 
  and 
  

   coloration 
  indicate 
  its 
  relationship 
  to 
  the 
  Ceylonese 
  M. 
  

   aspera, 
  &c. 
  

  

  Antennae 
  stout, 
  the 
  flagellum 
  thickly 
  covered 
  with 
  

   white 
  pubescence, 
  the 
  scape 
  and 
  base 
  of 
  flagellum 
  dark 
  

   piceous 
  ; 
  the 
  third 
  joint 
  narrowed 
  at 
  the 
  base 
  and 
  twice 
  

   the 
  length 
  of 
  the 
  fourth. 
  Head 
  as 
  wide 
  as 
  the 
  thorax 
  ; 
  

   slightly 
  rounded 
  in 
  front, 
  transverse 
  behind 
  ; 
  behind, 
  it 
  is 
  

   not 
  quite 
  so 
  long 
  as 
  the 
  eyes 
  ; 
  the 
  lower 
  edges 
  distinctly 
  

   margined, 
  irregularly 
  serrate, 
  below 
  the 
  eyes. 
  Antennal 
  

   tubercles 
  large, 
  smooth, 
  and 
  shining. 
  The 
  face 
  and 
  oral 
  

   region 
  rufo-testaceous, 
  the

  with 
  shorter, 
  white

  pale 
  testaceous. 
  

   Thorax 
  twice 
  as 
  long 
  as 
  broad 
  ; 
  the 
  sides 
  irregular, 
  not 
  

   contracted 
  in 
  the 
  middle 
  ; 
  on 
  the 
  sides, 
  behind 
  the 
  middle, 
  

   are 
  six 
  distinct 
  teeth 
  ; 
  the 
  basal 
  one 
  is 
  the 
  smallest, 
  the 
  

   apical 
  one 
  stouter 
  and 
  broader 
  than 
  the 
  others 
  ; 
  the 
  upper 
  

   edge 
  is 
  irregularly 
  toothed 
  ; 
  the 
  central 
  tooth 
  being 
  longer, 
  

   sharper, 
  and 
  more 
  distinct 
  than 
  the 
  lateral, 
  and 
  from 
  its 
  

   base 
  a

  keel 
  runs 
  towards 
  the 
  middle 
  of 
  the 
  

   mesonotum. 
  The 
  apex 
  of 
  the
