  Mordvilko 
  described 
  this 
  form 
  as 
  a 
  subspecies 
  of 
  rubi 
  Kaltenbach. 
  

   I 
  have 
  not 
  seen 
  it, 
  but 
  judging 
  from 
  his 
  description 
  it 
  is 
  a 
  good 
  species. 
  

   The 
  apterous 
  form 
  can 
  be 
  distinguished 
  from 
  rubi 
  Kaltenbach 
  by 
  the 
  

   differences 
  in 
  proportion 
  of 
  the 
  antennal 
  segments 
  (see 
  page 
  54). 
  

   I 
  quote 
  herewith 
  a 
  translation 
  of 
  Mordvilko 
  by 
  A. 
  J. 
  Bruman. 
  

  

  Apterous 
  viviparous 
  female. 
  — 
  Depth 
  of 
  frontal 
  furrow 
  represents 
  about 
  three- 
  

   tenths 
  the 
  distance 
  between 
  the 
  bases 
  of 
  the 
  antennae. 
  Mouth 
  of 
  furrow 
  about 
  

   two-thirds 
  this 
  distance. 
  The 
  projection 
  of 
  the 
  vertex 
  is 
  distinct. 
  Antennae 
  

   somewhat 
  longer 
  than 
  the 
  body. 
  The 
  third 
  segment 
  is 
  one 
  and 
  three-sevenths 
  to 
  

   one 
  and 
  one-half 
  times 
  longer 
  than 
  the 
  fourth 
  and 
  this 
  one 
  is 
  only 
  slightly 
  longer 
  

   than 
  the 
  fifth. 
  The 
  base 
  of 
  VI 
  equals 
  one-fifth 
  to 
  two-elevenths 
  the 
  length 
  of 
  

   the 
  third 
  segment, 
  and 
  the 
  unguis 
  of 
  the 
  sixth 
  segment 
  is 
  one 
  and 
  two-ninths 
  times 
  

   or 
  thereabouts 
  longer 
  than 
  the 
  third. 
  On 
  the 
  third 
  segment 
  near 
  the 
  base 
  there 
  

   are 
  3-4 
  sensoria, 
  its 
  longest 
  hairs 
  reach 
  three-fifths 
  to 
  four-fifths 
  of 
  the 
  diameter 
  of 
  

   the 
  proximal 
  part 
  of 
  the 
  segment. 
  The 
  cornicles 
  reach 
  one-fifth 
  to 
  two-ninths 
  

   the 
  length 
  of 
  the 
  body; 
  toward 
  the 
  base 
  they 
  become 
  wider, 
  at 
  one-fourth 
  

   to 
  one-third 
  from 
  the 
  base 
  they 
  become 
  narrow, 
  from 
  the 
  point 
  to 
  one-third 
  

   from 
  the 
  end 
  they 
  widen 
  and 
  finally, 
  at 
  the 
  flange 
  they 
  again 
  become 
  narrow. 
  

   Cornicles 
  without 
  sculpture, 
  except 
  at 
  the 
  very 
  tip 
  one 
  may 
  notice 
  2-3 
  trans- 
  

   verse, 
  ring-shaped 
  ribs. 
  The 
  cornicles 
  are 
  two 
  and 
  one-half 
  to 
  two 
  and 
  one- 
  

   third 
  times 
  longer 
  than 
  the 
  cauda. 
  The 
  cauda 
  is 
  long-triangular 
  with 
  uneven 
  

   laterial 
  edges, 
  with 
  4-5 
  bristly 
  hairs 
  on 
  each 
  side.
