  The 
  following 
  notes 
  are 
  based 
  on 
  the 
  type, 
  which 
  is 
  a 
  male 
  : 
  Head 
  

   not 
  thin; 
  frons 
  polished; 
  transverse 
  diameter 
  of 
  opening 
  between 
  

   clypeus 
  and 
  mandibles 
  a 
  little 
  longer 
  than 
  the 
  distance 
  from 
  the 
  

   opening 
  to 
  the 
  eye; 
  antennae 
  broken, 
  16 
  segments 
  remaining, 
  non& 
  

   of 
  the 
  flagellar 
  segments 
  twice 
  as 
  long 
  as 
  thick; 
  thorax 
  smooth 
  and 
  

   polished; 
  parapsidal 
  grooves 
  sparsely 
  hairy; 
  propodeum 
  polished, 
  

   with 
  a 
  short 
  stub 
  of 
  a 
  median 
  ridge 
  at 
  apex 
  and 
  a 
  slight 
  impression 
  

   just 
  before 
  the 
  stub; 
  first 
  abscissa 
  of 
  radius 
  fully 
  as 
  long 
  as 
  the 
  inner 
  

   side 
  of 
  stigma 
  ; 
  the 
  second 
  abscissa 
  of 
  radius 
  less 
  than 
  twice 
  the 
  first 
  ; 
  

   abdomen 
  missing; 
  head 
  and 
  thorax 
  black; 
  wings 
  dusky; 
  legs, 
  in- 
  

   cluding 
  all 
  coxae, 
  yellow. 
  Somewhat 
  resembles 
  meromyzae, 
  but 
  

   the 
  thorax 
  is 
  not 
  so 
  long 
  and 
  slender 
  as 
  in 
  that 
  species, 
  the 
  first 
  

   abscissa 
  of 
  radius 
  is 
  longer, 
  and 
  the 
  propodeum 
  is 
  without 
  the- 
  

   median 
  carina 
  which 
  is 
  usually 
  distinct 
  in 
  meromyzae.
