  believe 
  Dr. 
  Capron 
  has 
  met 
  with 
  the 
  species 
  in 
  his 
  

   neighbourhood. 
  It 
  forms 
  the 
  genus 
  Theroholus, 
  Forst. 
  

   According 
  to 
  Brischke 
  (Schr. 
  Nat. 
  Ges. 
  Danzig, 
  1878, 
  

   p. 
  108) 
  it 
  has 
  been 
  bred 
  from 
  the 
  maggots 
  of 
  Pegomyia 
  

   conformis, 
  Fall. 
  The 
  ambiguous 
  character 
  of 
  the 
  wings 
  

   would 
  allow 
  this 
  species 
  to 
  enter 
  the 
  genus 
  DiacJiasma, 
  

   if 
  it 
  were 
  not 
  that 
  the 
  2d 
  abscissa 
  is 
  a 
  little 
  too 
  long.

  Haliday

  in

  collection,

  The 
  rugosity 
  of 
  the 
  scutellum

  the 
  black 
  coxse 
  make 
  the 
  species
