  When 
  revising 
  Walker's 
  species 
  in 
  1899 
  I 
  accepted 
  that 
  

   writer's 
  arrangement 
  and 
  labelling 
  of 
  his 
  Ochlerus 
  scaber 
  at 
  

   its 
  face 
  value, 
  although 
  on 
  founding 
  my 
  genus 
  Hemingius 
  on 
  

   that 
  species 
  I 
  stated 
  that 
  the 
  type 
  did 
  not 
  agree 
  with 
  the 
  

   description. 
  I 
  wrote 
  : 
  " 
  Walker, 
  in 
  his 
  diagnosis 
  of 
  this 
  

   species, 
  describes 
  the 
  scutellum 
  as 
  ' 
  more 
  than 
  half 
  the 
  length 
  

   of 
  the 
  abdomen,' 
  whereas 
  it 
  reaches 
  the 
  apex 
  of 
  the 
  abdomen 
  

   &c." 
  On 
  further 
  consideration 
  I 
  think 
  it 
  certain 
  that 
  

   Walker 
  misplaced 
  the 
  labels, 
  for 
  Stal 
  saw 
  Dallas's 
  type 
  before 
  

   Walker 
  commenced 
  his 
  Catalogue, 
  and 
  I 
  therefore 
  sink 
  my 
  

   genus 
  and 
  follow 
  Stal's 
  determination.
