  This 
  large 
  species 
  on 
  Rubus 
  is 
  rather 
  close 
  in 
  appearance 
  to 
  two 
  

   other 
  species 
  on 
  Rubus 
  which 
  are 
  described 
  in 
  this 
  paper 
  as 
  davidsoni 
  

   and 
  maxima. 
  It 
  may 
  be 
  distinguished 
  from 
  them 
  by 
  the 
  large 
  

   dusky 
  spot 
  on 
  the 
  tips 
  of 
  the 
  wings 
  and 
  by 
  the 
  dark 
  colored 
  antennae, 
  

   segment 
  III 
  of 
  which 
  is 
  conspicuously 
  shorter 
  than 
  the 
  cornicle 
  and 
  

   has 
  20-30 
  sensoria. 
  

  

  Alate 
  viviparous 
  female. 
  — 
  Antennae 
  about 
  as 
  long 
  as 
  body, 
  dark 
  

   colored, 
  except 
  base 
  of 
  III, 
  hairs 
  conspicuous, 
  about 
  as 
  long 
  as 
  width 
  

   of 
  segment, 
  III 
  with 
  20-30 
  sensoria 
  scattered 
  over 
  nearly 
  the 
  entire 
  

   length 
  and 
  not 
  in 
  a 
  straight 
  row. 
  Antennal 
  tubercles 
  fairly 
  large. 
  

   Beak 
  extending 
  usually 
  to 
  third 
  coxae. 
  In 
  some 
  specimens 
  there 
  are 
  

   two 
  tubercles 
  showing 
  on 
  the 
  posterior, 
  dorsal 
  portion 
  of 
  the 
  head. 
  

   The 
  prothorax 
  has 
  two 
  dorsal 
  tubercles, 
  and 
  a 
  lateral 
  tubercle 
  on 
  

   each 
  side. 
  The 
  front 
  wings 
  have 
  a 
  dusky 
  spot 
  at 
  the 
  tips. 
  This 
  is 
  

   darker 
  in 
  some 
  specimens 
  than 
  in 
  others. 
  The 
  abdomen 
  has 
  several 
  

   lateral 
  tubercles, 
  one 
  specimen 
  showing 
  five 
  in 
  front 
  of 
  the 
  cornicle 
  

   and 
  one 
  caudad 
  of 
  the 
  cornicle. 
  Hairs 
  are 
  present 
  around 
  each 
  

   tubercle. 
  The 
  cornicles 
  are 
  long, 
  curved, 
  conspicuously 
  swollen 
  and 
  

   distinctly 
  reticulated. 
  The 
  cauda 
  is 
  long, 
  slender 
  and 
  constricted, 
  

   with 
  5-6 
  lateral 
  hairs.
