  the 
  hair 
  on 
  the 
  under 
  side 
  of 
  the 
  metatarsus 
  rufous; 
  the 
  

   apex 
  of 
  the 
  tarsi 
  rufous. 
  The 
  femora 
  and 
  tibiae 
  are 
  normal, 
  

   not 
  dilated, 
  except 
  that 
  the 
  hinder 
  tibiae 
  on 
  the 
  inner 
  side 
  

   are 
  triangularly 
  produced, 
  but 
  not 
  sharply, 
  the 
  apex 
  being 
  

   rounded. 
  Abdomen 
  shining, 
  impunctate; 
  the 
  base 
  of 
  the 
  

   segments 
  belted 
  with 
  white, 
  depressed 
  pile 
  ; 
  the 
  second 
  to 
  

   fourth 
  segment 
  with 
  wide 
  transverse 
  furrows 
  near 
  the 
  

   base 
  ; 
  the 
  ventral 
  segments 
  smooth, 
  shining 
  ; 
  their 
  apices 
  

   fringed 
  with 
  short, 
  white 
  hair 
  ; 
  the 
  sides 
  of 
  the 
  third 
  and 
  

   fourth 
  with 
  long, 
  white 
  hair 
  ; 
  the 
  penultimate 
  segment 
  

   broadly 
  depressed 
  in 
  the 
  middle, 
  with 
  a 
  smaller, 
  somewhat 
  

   pear-shaped, 
  depression 
  on 
  either 
  side 
  at 
  the 
  apex. 
  

  

  This 
  is 
  perhaps 
  not 
  a 
  true 
  Nomia. 
  The 
  trophi 
  do 
  not 
  

   differ 
  in 
  form 
  from 
  those 
  of 
  that 
  genus. 
  The 
  only 
  point 
  

   in 
  which 
  the 
  legs 
  agree 
  with 
  those 
  of 
  Nomia 
  is 
  in 
  the 
  

   projecting 
  apex 
  of 
  the 
  hinder 
  tibiae. 
  It 
  differs 
  in 
  the 
  

   interstitial 
  first 
  recurrent 
  nervure 
  and 
  in 
  the 
  shorter 
  wings.

   M.

  a 
  very 
  different 
  species 
  from 
  M.

  the
