  Host.

  Unknown. 
  

  

  Known 
  only 
  from 
  the 
  holotypes 
  of 
  atricollis 
  and 
  nawaasorum, 
  

   and 
  one 
  additional 
  female 
  specimen, 
  labeled 
  "Algonquin, 
  111. 
  18-12- 
  

   95-134, 
  4855." 
  The 
  only 
  complete 
  antennae 
  are 
  those 
  on 
  the 
  type 
  of 
  

   nawaasorum, 
  which 
  have 
  43 
  segments. 
  A 
  thorough 
  studj' 
  of 
  the 
  

   types 
  shows 
  nawaasorum 
  to 
  be, 
  without 
  doubt 
  conspecific 
  with 
  

   atricollis.

  Superficially 
  quite 
  similar

  differs 
  especially 
  

   in 
  the 
  thorax 
  being 
  smooth

  on 
  the 
  propodeum
