  Described 
  from 
  7 
  females 
  and 
  one 
  male 
  ; 
  the 
  type 
  and 
  two 
  female 
  

   paratypes 
  were 
  reared 
  from 
  the 
  above 
  host 
  at 
  Knoxville,

  the 
  allotype 
  was 
  reared 
  by 
  E. 
  A. 
  Cushman 
  from 
  Mompha, 
  

   at 
  Vienna, 
  Virginia, 
  under 
  Quaintance

  two 
  female 
  para- 
  

   types 
  were 
  secured 
  by 
  H. 
  B. 
  Weiss 
  from 
  seed 
  capsules 
  of 
  evening 
  

   primrose 
  in 
  Middlesex

  ; 
  and 
  two 
  other 
  paratypes

  All 
  the 
  specimens 
  agree 
  very 
  closely 
  with 
  the 
  type 
  in 
  color 
  and 
  

   structure; 
  the 
  number 
  of 
  segments 
  in 
  the 
  antennae 
  varies 
  from 
  33 
  

   to 
  36.
