  As 
  I 
  cannot 
  trace 
  any 
  record 
  of 
  Monodontomerus 
  pachypsyllae, 
  Ashm. 
  , 
  and 
  the 
  name 
  

   appears 
  to 
  have 
  existed 
  up 
  to 
  1916 
  in 
  MS. 
  only, 
  its 
  authorship 
  should 
  be 
  credited 
  

   to 
  Viereck, 
  not 
  to 
  Ashmead.
