   loDg 
  triangular, 
  the 
  sides 
  bent 
  a 
  little 
  beyond 
  the 
  middle, 
  before 
  which 
  

   they 
  are 
  broadly 
  elevated 
  a 
  little, 
  the

  acutaugulate, 
  the

  plane, 
  the 
  median

  hardly 
  percepti-

  consisting 
  of 
  a 
  pair

  roundly 
  truncate, 
  the 
  basal 
  half 
  gradually 
  

   tapering 
  and 
  beyond 
  again 
  enlarging 
  to 
  somewhat

  This 
  species 
  is 
  certainly 
  very 
  closely 
  allied 
  in 
  structure 
  to 
  the 
  next, 
  

   M. 
  cinereus, 
  and 
  may 
  prove 
  to 
  be 
  a 
  variety 
  of 
  it, 
  found 
  in 
  difterent 
  sta- 
  

   tions. 
  It 
  wholly 
  lacks, 
  however, 
  the 
  cinereous 
  speckling 
  so 
  characteris- 
  

   tic 
  of 
  typical 
  examples 
  of 
  the 
  latter 
  species, 
  .with 
  the 
  rusty 
  hue 
  of 
  the 
  

   pronotum. 
  

  

  Some 
  individuals 
  are 
  much 
  smaller 
  than, 
  hardly 
  more 
  than 
  half 
  as 
  

   large 
  as, 
  others; 
  the 
  measurements 
  are 
  taken 
  from 
  the 
  larger 
  and 
  appar- 
  

   ently 
  commoner 
  forms.
