  U.S.N.M. 
  

  

  Described 
  from 
  nine 
  females 
  and 
  six 
  males 
  all 
  taken 
  at 
  the 
  type- 
  

   locality 
  by 
  E. 
  M. 
  Walker 
  on 
  July 
  25, 
  1918. 
  

  

  The 
  only 
  variations 
  of 
  moment 
  are 
  in 
  the 
  extent 
  of 
  the 
  yellow 
  

   markings 
  in 
  the 
  male 
  ; 
  the 
  yellow 
  spots 
  on 
  postscutellum, 
  first 
  tergite 
  

   and 
  the 
  inner 
  one 
  on 
  the 
  hind 
  coxae 
  sometimes 
  wanting 
  and 
  the 
  first 
  

   tergite 
  entirely 
  black. 
  In 
  other 
  specimens 
  these 
  markings 
  as 
  well 
  as 
  

   the 
  others 
  are 
  larger 
  than 
  in 
  the 
  allotype.
