  I 
  thought 
  at 
  first 
  this 
  might 
  be 
  the 
  male 
  of 
  M. 
  negligenda, 
  but 
  it 
  

   comes 
  from 
  a 
  different 
  locality 
  and 
  differs 
  in 
  too 
  many 
  respects. 
  It 
  is 
  

   considerably 
  smaller 
  than 
  M. 
  assimilis 
  Smith, 
  with 
  shorter 
  antennae. 
  

   The 
  marginal 
  cell 
  is 
  longer 
  and 
  relatively 
  narrower 
  than 
  in 
  M. 
  atrata 
  

   Smith.
