  Lane 
  (1945) 
  has 
  very 
  adequately 
  redescribed 
  this 
  Brazilian 
  species. 
  

   It 
  resembles 
  M. 
  (M.) 
  stonei, 
  new 
  species, 
  in 
  general 
  coloration 
  and 
  

   structure, 
  the 
  mesonotum 
  yellowish 
  with 
  brown 
  dots, 
  the 
  scutellum 
  

   yellow 
  with 
  median 
  brown 
  spot 
  and 
  four 
  marginal 
  bristles, 
  forelegs 
  

   and 
  midlegs 
  yellowish, 
  the 
  hind 
  femur 
  and 
  tibia 
  black 
  and 
  scarcely 
  

   swoUen 
  and 
  hind 
  tarsi 
  unspined. 
  The 
  wings, 
  however, 
  in 
  addition 
  

   to 
  the 
  two 
  anterior 
  black 
  spots, 
  have 
  smaller, 
  rather 
  strong 
  spots 
  at 
  

   the 
  wing 
  margin 
  m 
  cells 
  R5 
  and 
  Mi, 
  and 
  across 
  the 
  apex 
  of 
  cell 
  M2. 
  

   The 
  polished, 
  brown, 
  lateral 
  spots 
  on 
  the 
  abdomen, 
  which 
  are 
  small 
  

   in 
  stonei, 
  are 
  larger 
  and 
  narrowly 
  connected 
  across 
  the 
  anterior 
  margin 
  

   of 
  each 
  tergite 
  in 
  multilineata. 
  

  

  The 
  male 
  genitalia 
  of 
  multilineata 
  are 
  of 
  the 
  same 
  type 
  as 
  those 
  of 
  

   stonei, 
  but 
  there 
  are 
  four 
  rather 
  than 
  two 
  bristles 
  at 
  the 
  base 
  of 
  the
