  prove 
  to 
  be 
  the 
  same 
  as 
  other 
  specimens 
  which 
  I 
  had 
  already 
  described 
  

   in 
  manuscript 
  as 
  davidsoni, 
  new 
  species. 
  Swain 
  did 
  have 
  specimens 
  

   of 
  rubi 
  Kaltenbach 
  from 
  other 
  sources, 
  but 
  did 
  not 
  describe 
  them. 
  

  

  Mordvilko 
  under 
  rubi 
  Kaltenbach 
  considers 
  four 
  subspecies. 
  One 
  

   of 
  these 
  is 
  the 
  typical 
  rubi 
  Kaltenbach. 
  Another 
  is 
  fragarieUum 
  

   Theobald 
  which 
  I 
  believe 
  to 
  be 
  the 
  same 
  as 
  rubi 
  Kaltenbach. 
  The 
  

   other 
  two 
  subspecies 
  are 
  apparently 
  distinct 
  and 
  I 
  have 
  elevated 
  

   them 
  to 
  the 
  rank 
  of 
  species. 
  These 
  are 
  discussed 
  under 
  the 
  indi- 
  

   vidual 
  species. 
  I 
  give 
  herewith 
  a 
  translation 
  of 
  Mordvilko's 
  key 
  for 
  

   the 
  separation 
  of 
  his 
  four 
  subspecies. 
  

  

  1. 
  (6) 
  The 
  third 
  segment 
  of 
  the 
  antennae 
  exceeds 
  the 
  fourth 
  only 
  slightly, 
  for 
  

   instance, 
  one 
  and 
  one-third 
  to 
  one-seventh 
  times; 
  the 
  unguis 
  of 
  the 
  sixth 
  segment 
  

   almost 
  equals 
  the 
  third 
  segment 
  (in 
  wingless 
  females 
  somewhat 
  shorter 
  and 
  in 
  

   winged, 
  somewhat 
  though 
  very 
  little 
  longer). 
  

  

  2. 
  (5) 
  The 
  base 
  of 
  the 
  sixth 
  segment 
  of 
  the 
  antennae 
  consists 
  of 
  one-seventh 
  

   to 
  one-sixth 
  the 
  length 
  of 
  the 
  third 
  segment, 
  reaching 
  0.17-0.19 
  and 
  almost 
  0.20 
  

   mm., 
  but 
  at 
  times 
  (in 
  the 
  case 
  of 
  long 
  antennae) 
  0.22. 
  

  

  3. 
  (4) 
  The 
  cornicles 
  even 
  in 
  the 
  wingless 
  females 
  are 
  dark, 
  in 
  front 
  of 
  the 
  

   flange 
  they 
  are 
  usually 
  very 
  slightly 
  but 
  nevertheless 
  noticeably 
  swollen; 
  they 
  

   reach 
  one-fourth 
  to 
  two-ninths 
  the 
  length 
  of 
  the 
  body 
  (in 
  wingless 
  females); 
  

   cauda 
  with 
  3-4 
  bristly 
  lateral 
  hairs 
  Ac. 
  rubi 
  amurense, 
  new 
  subspecies. 
  

  

  4. 
  (3) 
  Cornicles 
  in 
  wingless 
  females 
  light 
  colored; 
  in 
  front 
  of 
  the 
  flange 
  there 
  

   is 
  hardly 
  any 
  swelling 
  noticeable; 
  the 
  cornicles 
  reach 
  two-sevenths 
  to 
  one-third 
  

   the 
  length 
  of 
  the 
  body; 
  on 
  the 
  sides 
  of 
  the 
  cauda 
  are 
  5-6 
  bristly 
  

   hairs 
  Ac. 
  rubi 
  rubi 
  (Kaltenbach) 
  .

  (2) 
  The 
  base 
  of 
  the 
  sixth 
  segment 
  of 
  the 
  antennae 
  consists 
  of 
  one-fifth 
  the 
  

   length 
  of 
  the 
  third, 
  reaching 
  0.22 
  mm 
  Ac. 
  rubi 
  fragarieUum 
  (Theobald). 
  

  

  6. 
  (1) 
  The 
  third 
  segment 
  of 
  the 
  antenna 
  exceeds 
  the 
  fourth 
  distinctly, 
  for 
  

   instance, 
  one 
  and 
  two-fifths 
  to 
  one 
  and 
  one-half 
  times 
  and 
  the 
  unguis 
  of 
  the 
  sixth 
  

   segment, 
  even 
  in 
  the 
  wingless 
  females 
  exceeds 
  the 
  third 
  segment 
  distinctly, 
  for 
  

   instance, 
  one 
  and 
  two-fifths 
  to 
  one 
  and 
  one-half 
  times 
  and 
  the 
  unguis, 
  even 
  in 
  

   wingless 
  females 
  exceeds 
  the 
  third 
  segment 
  distinctly, 
  for 
  instance, 
  one 
  and 
  two- 
  

   ninths 
  times; 
  the 
  base 
  of 
  the 
  sixth 
  segment 
  consists 
  of 
  about 
  one-fifth 
  the 
  length 
  

   of 
  the 
  third 
  reaching 
  0.17-0.18 
  mm 
  Ac. 
  rubi 
  zhuravlevi, 
  new 
  subspecies.
