  M. 
  cedipus, 
  but 
  the 
  latter 
  is 
  easily 
  known 
  from 
  it 
  by 
  the 
  

   thorax 
  beinj; 
  contracted 
  in 
  the 
  middle. 
  

  

  Head 
  large, 
  a 
  little 
  broader 
  than 
  the 
  thorax 
  ; 
  coarsely 
  

   longitudinally 
  striolated 
  ; 
  the 
  striae 
  running 
  into 
  reticula- 
  

   tions 
  towards 
  the 
  antennae 
  ; 
  black 
  ; 
  the 
  front 
  and 
  vertex 
  

   broadly 
  ferruginous 
  ; 
  the 
  ferruginous 
  colour 
  extending 
  

   to 
  a 
  little 
  below 
  the 
  bottom 
  of 
  the 
  eyes 
  : 
  the 
  antennal 
  

   tubercles 
  and 
  a 
  stripe 
  on 
  the 
  mandibles 
  ferruginous. 
  The 
  

   scape 
  of 
  the 
  antennas 
  covered 
  with 
  long 
  silvery 
  hairs, 
  the 
  

   flagellum 
  sparsely 
  with 
  a 
  pale 
  down. 
  Thorax 
  short, 
  not 
  

   much 
  longer 
  than 
  the 
  head 
  ; 
  coarsely 
  rugosely 
  punctured, 
  

   sparsely 
  covered 
  with 
  black 
  hairs 
  ; 
  the 
  apex 
  of 
  the 
  median 
  

   segment 
  oblique; 
  the 
  pleurae 
  excavated, 
  shining, 
  impunc- 
  

   tate 
  ; 
  the 
  base 
  and 
  apex 
  a 
  little 
  pilose 
  ; 
  at 
  the 
  top 
  in 
  

   the 
  middle 
  the 
  median 
  segment 
  ends 
  in 
  a 
  sharp 
  spine. 
  

   Abdomen 
  a 
  little 
  longer 
  than 
  the 
  head 
  and 
  thorax 
  united 
  ; 
  

   the 
  base 
  obliquely 
  truncated, 
  with 
  a 
  narrow 
  margin 
  at 
  its 
  

   apex, 
  and 
  with 
  a 
  spot 
  of 
  pale 
  golden 
  pubescence 
  in 
  its 
  

   centre 
  above 
  ; 
  at 
  the 
  apex 
  of 
  the 
  second 
  segment 
  there 
  is 
  a 
  

   central 
  and 
  a 
  lateral 
  somewhat 
  larger 
  o\al 
  mark 
  of 
  pale 
  

   golden 
  pubescence 
  ; 
  the 
  other 
  segments 
  have 
  a 
  somewhat 
  

   squarish 
  mark 
  in 
  the 
  middle 
  of 
  the 
  same 
  colour. 
  The 
  

   ventral 
  segments 
  punctured, 
  the 
  basal 
  segment 
  much 
  

   more 
  strongly 
  than 
  the 
  others 
  ; 
  they 
  are 
  fringed 
  with 
  

   fulvous 
  hairs. 
  Legs

  black,

  The 
  present 
  species 
  may, 
  of 
  course, 
  be 
  the 
  2 
  of 
  my 
  

   M. 
  cedipus, 
  but 
  this 
  is 
  a 
  point 
  which 
  can 
  only 
  be 
  

   decided 
  by 
  direct 
  observation. 
  The 
  head 
  in 
  M 
  . 
  RotJincyi 
  

   is 
  wider 
  compared 
  to 
  the 
  prothorax 
  ; 
  the 
  mesothorax 
  is 
  

   stoutly 
  spined 
  ; 
  the 
  front 
  and 
  vertex 
  strongly 
  longi- 
  

   tudinally 
  striated 
  all 
  over, 
  while 
  in 
  M. 
  cedipus 
  it 
  is 
  only 
  

   punctured 
  ; 
  the 
  head 
  behind 
  the 
  eyes 
  in 
  M. 
  adipus 
  is 
  much 
  

   more 
  thickly 
  covered 
  with 
  white 
  hairs. 
  There 
  is 
  no 
  

   appreciable 
  difference 
  in 
  the 
  form 
  and 
  coloration 
  of 
  the 
  

   two 
  ; 
  in 
  M. 
  Rothneyi 
  the 
  sides 
  of 
  the 
  median 
  segment 
  are
