  vertex, 
  28; 
  width 
  of 
  front 
  at 
  base 
  of 
  antennae,

  head, 
  75. 
  Frontal 
  calli 
  promi- 
  

   nent; 
  vertex, 
  frontal 
  calli, 
  and 
  face 
  shining; 
  silvery-tomentose 
  areas 
  

   of 
  face 
  as 
  in 
  male 
  but 
  much 
  more 
  prominent 
  ; 
  a 
  similar 
  area 
  on 
  ocular 
  

   orbit 
  below 
  frontal 
  callus 
  and 
  a 
  transverse 
  band 
  between 
  frontal 
  

   callus 
  and 
  vertex. 
  Third 
  antennal 
  segment 
  proportionately 
  a 
  little 
  

   longer 
  than 
  in 
  the 
  male. 
  Pattern 
  of 
  mesonotum 
  essentially 
  as 
  in 
  male 
  

   except 
  that 
  the 
  black 
  areas, 
  especially 
  of 
  the 
  presutural 
  lateral 
  spots, 
  

   are 
  larger; 
  the 
  bright 
  tomentum, 
  however, 
  is 
  grayish 
  yellow 
  rather 
  

   than 
  golden 
  and 
  is 
  not 
  so 
  long 
  or 
  dense 
  as 
  in 
  the 
  male. 
  No 
  erect 
  pile 
  

   on 
  mesonotum 
  or 
  upper 
  parts 
  of 
  pleura. 
  Abdomen 
  wholly 
  black, 
  

   posterior 
  margins 
  of 
  first, 
  second, 
  and 
  third 
  sternites, 
  however, 
  very 
  

   narrowly 
  reddish; 
  tergites 
  with 
  a 
  distinct 
  steel-blue 
  cast; 
  sternites 
  

   bluish 
  in 
  certain 
  lights.

  Remarks. 
  — 
  This 
  species 
  traces, 
  rather 
  imperfectly 
  because 
  of 
  the 
  

   coloration 
  of 
  the 
  legs 
  and 
  abdomen, 
  to 
  Odontomyia 
  ilnalis 
  (Walker) 
  in 
  

   Brimetti's 
  key. 
  Though 
  both 
  Walker's 
  description 
  and 
  Brunetti's 
  

   redescription 
  fail 
  to 
  mention 
  certain 
  important 
  characters, 
  finalis 
  

   is 
  probably 
  a 
  closely 
  related 
  species.
