  Hab. 
  Trincomali,

  (

  In 
  Bingham's 
  Table, 
  {I.e., 
  p. 
  5) 
  this 
  species 
  comes 
  in 
  at 
  

   " 
  b 
  l 
  . 
  Spot 
  silvery 
  white, 
  b 
  2 
  . 
  First 
  abdominal 
  segment 
  not 
  

   ciliated 
  with 
  white 
  hairs, 
  a 
  3 
  . 
  Second 
  abdominal 
  segment 
  

   with 
  a 
  transverse 
  band 
  of 
  white 
  pubescence 
  on 
  its 
  apical 
  

   margin 
  in 
  addition 
  to 
  the 
  spot," 
  but 
  it 
  is 
  very 
  different 
  

   from 
  M. 
  decora 
  Sm., 
  the 
  representative 
  of 
  this 
  section. 
  

   With 
  M. 
  trimaculcita 
  it 
  has 
  no 
  near 
  relationship; 
  but, 
  

   judging 
  from 
  the 
  descriptions, 
  it 
  must 
  be 
  nearly 
  related 
  

   to 
  M. 
  coronota 
  Bingham. 
  It 
  is 
  not 
  M. 
  stridula 
  Rossi, 
  

   sec. 
  Rad. 
  = 
  coronota 
  Fab., 
  for 
  that 
  has 
  the 
  first 
  segment 
  

   "arme 
  de 
  dents 
  et 
  carene," 
  which 
  is 
  not 
  the 
  case 
  here; 
  nor 
  

   has 
  it 
  the 
  pygidial 
  area 
  "ovale, 
  assez 
  grand, 
  finement 
  strie," 
  

   nor 
  are 
  the 
  tarsi 
  reddish. 
  It 
  is 
  not 
  the 
  coronota 
  of 
  Saussure, 
  

   Reise 
  der 
  Novara, 
  Hymen, 
  p. 
  106, 
  who 
  quotes 
  his 
  Ceylonese 
  

   species 
  as 
  doubtfully 
  identical 
  with 
  M. 
  coronota 
  Fab. 
  

   M. 
  coronota 
  Sauss. 
  has 
  the 
  pleurae 
  "omnis 
  excavata 
  et 
  

   polita, 
  postice 
  ad 
  marginem 
  leviter 
  rugulata," 
  while 
  in 
  the 
  

   present 
  species, 
  the 
  pro- 
  and 
  meta-pleurae, 
  are 
  strongly 
  

   and 
  coarsely 
  punctured. 
  

  

  Head 
  wider 
  than 
  the 
  thorax; 
  black, 
  the 
  tubercles 
  and 
  

   the 
  middle 
  of 
  the 
  mandibles 
  broadly 
  rufous; 
  coarsely 
  

   punctured, 
  the 
  punctures 
  large 
  and 
  deep 
  ; 
  there 
  is 
  a 
  dis- 
  

   tinct 
  keel 
  down 
  the 
  middle 
  of 
  the 
  front; 
  thickly 
  covered 
  

   with 
  long, 
  fuscous 
  hair; 
  the 
  tubercles 
  large, 
  shining, 
  im- 
  

   punctate, 
  a 
  fine 
  keel 
  between 
  them 
  ; 
  over 
  them 
  is 
  a 
  

   moderately 
  thick, 
  curved 
  keel; 
  behind 
  the 
  eyes 
  the 
  head 
  

   is 
  obliquely 
  narrowed. 
  Antennae 
  stout, 
  the 
  scape 
  shining, 
  

   sparsely 
  covered 
  with 
  longish, 
  pale 
  hairs; 
  the 
  flagellum 
  

   opaque, 
  covered 
  with 
  a 
  white 
  down. 
  Thorax 
  distinctly 
  

   narrower 
  than 
  the 
  head, 
  narrowed 
  towards 
  the 
  base 
  and 
  

   apex 
  ; 
  the 
  pro- 
  and 
  meso-notum 
  coarsely 
  longitudinally
