   dorsally, 
  pale 
  golden 
  laterally 
  and 
  beneath, 
  the 
  line 
  of 
  junction 
  of 
  the 
  colours 
  rather 
  

   deeply 
  incised, 
  the 
  black 
  wedges 
  situated 
  at 
  the 
  apices 
  of 
  the 
  tergites. 
  Tergites 
  

   4-7 
  each 
  with 
  a 
  small 
  median 
  basal 
  whitish 
  spot. 
  Legs 
  dark 
  ; 
  undersides 
  of 
  femora, 
  

   tibiae, 
  and 
  first 
  tarsal 
  segments 
  lighter 
  ; 
  no 
  white 
  markings 
  on 
  any 
  of

  outstanding 
  ones 
  ligulate. 
  Upper 
  fork-cell 
  

   nearly 
  three 
  times

  nearer

  than 
  is 
  

   that 
  of 
  the 
  lower 
  fork-cell. 
  Wing-length, 
  3 
  mm. 
  

  

  Cotypes, 
  2$ 
  (Fiebrig). 
  No 
  exact 
  data. 
  

  

  This 
  species 
  is 
  probably 
  related 
  to 
  W. 
  Irinidadensis, 
  Theo., 
  differing 
  in 
  the 
  entire 
  

   absence 
  of 
  white 
  on 
  the 
  tarsi 
  and 
  in 
  other 
  particulars. 
  I 
  think 
  that 
  Phoniomyia 
  

   can 
  be 
  recognised 
  as 
  a 
  good 
  subgenus 
  on 
  the 
  character 
  of 
  the 
  proboscis, 
  but 
  whether 
  

   its 
  recent 
  division 
  by 
  Bonne-Wepster 
  & 
  Bonne 
  into 
  Phoniomyia, 
  Dodecamyia 
  and 
  

   Dyarina 
  can 
  be 
  maintained 
  seems 
  open 
  to 
  serious 
  question. 
  

  

  Psorophora 
  (Psorophora) 
  ciliata, 
  Fab. 
  

  

  Some 
  of 
  the 
  examples 
  in 
  the 
  collection 
  (all 
  are 
  females) 
  seem 
  to 
  me 
  to 
  be 
  indis- 
  

   tinguishable 
  from 
  the 
  North 
  American 
  species. 
  They 
  have 
  the 
  scales 
  on 
  the 
  pre- 
  

   scutellar 
  space 
  mostly 
  flat 
  and 
  white, 
  with 
  a 
  narrow 
  area 
  of 
  golden 
  ones 
  in 
  the 
  middle. 
  

   Some 
  others 
  may 
  perhaps 
  represent 
  a 
  distinct 
  species 
  (? 
  tibialis, 
  R.-D.) 
  ; 
  in 
  these 
  

   the 
  pre-scutellar 
  scales 
  are 
  all 
  narrow 
  and 
  golden.
