  This 
  species 
  seems 
  to 
  be 
  widely 
  distributed 
  in 
  Europe 
  and 
  on 
  the 
  

   North 
  American 
  continent. 
  In 
  America, 
  however, 
  there 
  is 
  another 
  

   similar 
  species 
  (see 
  sensoriata 
  Mason) 
  which, 
  no 
  doubt, 
  has 
  often 
  been 
  

   confused 
  with 
  rubi. 
  In 
  many 
  of 
  the 
  references 
  in 
  literature 
  it 
  is 
  

   impossible 
  to 
  tell 
  to 
  which 
  one 
  the 
  writer 
  referred. 
  Gillette 
  had 
  this 
  

   new 
  species 
  when 
  he 
  wrote: 
  "A 
  very 
  similar 
  species 
  taken 
  by 
  Mr. 
  

   Bragg 
  at 
  Lawrence, 
  Kans., 
  differs 
  by 
  having 
  cornicles 
  decidedly 
  

   shorter 
  and 
  having 
  joint 
  4 
  of 
  the 
  antenna 
  in 
  the 
  alate 
  viviparae 
  well 
  

   set 
  with 
  sensoria. 
  " 
  Dr. 
  C. 
  P. 
  Gillette 
  kindly 
  lent 
  me 
  this 
  slide 
  for 
  

   examination. 
  Still 
  another 
  species 
  which 
  might 
  be 
  confused 
  with 
  

   rubi 
  Kaltenbach 
  is 
  described 
  in 
  this 
  paper 
  as 
  reticulata, 
  new 
  species. 
  

  

  The 
  typical 
  rubi 
  Kaltenbach, 
  as 
  fixed 
  by 
  Gillette, 
  Van 
  der 
  Goot, 
  

   and 
  Mordvilko 
  and 
  which 
  is 
  accepted 
  here, 
  has 
  sensoria 
  only 
  on 
  

   segment 
  III, 
  while 
  sensoriata 
  Mason 
  has 
  them 
  also 
  on 
  IV 
  and 
  V. 
  

   Gillette 
  says 
  that 
  specimens 
  from 
  England 
  examined 
  by 
  him 
  are 
  a 
  

   little 
  smaller 
  but 
  agree 
  in 
  other 
  respects 
  with 
  American 
  specimens. 
  

  

  The 
  species 
  described 
  by 
  Swain 
  in 
  1919 
  is 
  not 
  rubi 
  Kaltenbach. 
  

   He 
  described 
  specimens 
  received 
  from 
  Gillette. 
  I 
  have 
  had 
  the 
  

   privilege 
  of 
  examing 
  these 
  same 
  slides, 
  kindly 
  lent 
  by 
  Ferris, 
  and 
  they
