  Remarks. 
  — 
  The 
  male 
  genitalia 
  are 
  most 
  distinctive, 
  the 
  simple 
  

   apices 
  of 
  the 
  parameres 
  allying 
  M. 
  (M.) 
  texana 
  with 
  M. 
  (M.) 
  macfiei, 
  

   new 
  species. 
  However, 
  the 
  external 
  features, 
  as 
  nearly 
  as 
  can 
  be 
  

   ascertained 
  from 
  the 
  badly 
  damaged 
  specimen, 
  are 
  closer 
  to 
  other 
  

   species, 
  the 
  wing 
  markings 
  being 
  nearly 
  like

  of
