  Biology. 
  — 
  I 
  have 
  found 
  this 
  species 
  sparingly 
  on 
  the 
  stems 
  of 
  

   raspberry, 
  never 
  on 
  the 
  leaves. 
  Pergande 
  says 
  in 
  his 
  notes: 
  "Found 
  

   on 
  stems 
  of 
  Rubus, 
  which 
  they 
  sometimes 
  covered 
  for 
  a 
  distance 
  of 
  

   several 
  inches. 
  Drop 
  readily, 
  if 
  disturbed." 
  It 
  probably 
  remains 
  

   on 
  Rubus 
  throughout 
  the 
  year. 
  I 
  have 
  examined 
  specimens 
  taken

  This 
  species 
  is 
  not 
  known 
  to 
  me. 
  It 
  was 
  first 
  taken 
  by 
  Thomas 
  

   at 
  Carbondale, 
  111., 
  on 
  May 
  26, 
  1878, 
  and 
  described 
  by 
  him 
  in 
  1880. 
  

  

  In 
  1913 
  Davis 
  redescribed 
  it 
  from 
  specimens 
  in 
  the 
  Illinois 
  collec- 
  

   tion, 
  which 
  he 
  considered 
  to 
  be 
  the 
  type 
  specimens 
  and 
  gave 
  camera 
  

   lucida 
  drawings. 
  These 
  appear 
  to 
  be 
  of 
  a 
  valid 
  species 
  of 
  Amplioro- 
  

   phora.
