  and 
  the 
  two 
  basal

  the 
  opening 
  between 
  clypeus

   greater

  the 
  opening 
  to 
  the

  a 
  

   stub

  a 
  median 
  ridge 
  at 
  apex; 
  second 
  abscissa

  radius 
  usually 
  

   more 
  than 
  twice 
  as 
  long 
  as 
  the 
  first; 
  last 
  abscissa 
  of

  not 
  

   longer 
  than 
  the

  Distribution. 
  — 
  From 
  Canada 
  to 
  North 
  Carolina, 
  as 
  judged 
  by 
  the 
  

   material 
  examined; 
  probably 
  occurs 
  wherever 
  its 
  primary 
  hosts 
  are 
  

   found. 
  

  

  Hosts. 
  — 
  Gnonmoschema 
  gallaesolidaginis

  The 
  above 
  notes 
  are 
  based 
  on 
  the 
  types 
  and 
  extensive 
  series 
  in 
  

   the 
  National 
  Museum 
  reared 
  from 
  Gnorimoschema 
  gallaesolidaginis 
  

   by 
  R. 
  A. 
  Cushman, 
  at 
  Vienna 
  and 
  East 
  Falls 
  Church, 
  Virginia, 
  and 
  

   northern 
  Pennsylvania, 
  and 
  by 
  R. 
  W. 
  Leiby 
  in 
  North 
  Carolina. 
  At 
  

   the 
  Gipsy 
  Moth 
  Laboratory 
  there 
  is 
  a 
  series 
  reared 
  from 
  the 
  same 
  

   host 
  taken 
  at 
  Melrose 
  Highlands, 
  Massachusetts. 
  I 
  have 
  been 
  un- 
  

   able 
  to 
  separate 
  fungicola 
  from 
  furtivus.
