  This 
  is 
  the 
  type 
  species 
  of 
  the 
  genus. 
  The 
  type 
  slide 
  (bearing 
  

   three 
  apterous 
  viviparous 
  females) 
  exists 
  in 
  the 
  British 
  Museum. 
  

   Frederick 
  Laing 
  writes 
  that 
  segment 
  III 
  of 
  these 
  specimens 
  have 
  

   from 
  30-34 
  sensoria, 
  reaching 
  nearly 
  the 
  length 
  of 
  the 
  segment. 
  

   Drawings 
  kindly 
  loaned 
  by 
  him 
  show 
  the 
  hairs 
  of 
  III 
  to 
  be 
  less 
  than 
  

   half 
  the 
  width 
  of 
  the 
  segment 
  and 
  capitate. 
  The 
  cornicle 
  is 
  shown 
  

   to 
  be 
  about 
  three-fifths 
  as 
  long 
  as 
  III, 
  moderately 
  slender, 
  conspic- 
  

   uously 
  swollen, 
  and 
  with 
  no 
  reticulations 
  or 
  imbrications. 
  

  

  As 
  explained 
  on 
  page 
  3, 
  this 
  species 
  is 
  known 
  only 
  from 
  the 
  type 
  

   slide. 
  

  

  AMPHOROPHORA 
  AMURENSIS

  Mordvilko 
  described 
  this 
  form 
  as 
  a 
  subspecies 
  of 
  rubi 
  Kalten- 
  

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

   good 
  species. 
  It 
  may 
  be 
  separated 
  from 
  its 
  near 
  relatives 
  by 
  the 
  

   characters 
  given 
  in 
  the 
  key 
  on 
  page 
  54. 
  I 
  quote 
  herewith 
  a 
  trans- 
  

   lation 
  of 
  Mordvilko 
  by 
  A. 
  J. 
  Bruman. 
  

  

  Apterous 
  viviparous 
  female. 
  — 
  Body 
  spindle 
  shaped. 
  Depth 
  of 
  frontal 
  fur- 
  

   row 
  is 
  two-sevenths 
  to 
  one-third 
  the 
  distance 
  between 
  the 
  bases 
  of 
  the 
  antennae. 
  

   Antennal 
  tubercles 
  quite 
  convex. 
  The 
  projection 
  of 
  the 
  vertex 
  is 
  distinct. 
  

   Antennae 
  only 
  slightly 
  longer 
  than 
  the 
  body 
  (one 
  and 
  one-twenty-fifth 
  to 
  one 
  

   and 
  one-fourteenth 
  times). 
  The 
  third 
  segment 
  is 
  one 
  and 
  one-fourth 
  to 
  one 
  

   and 
  one-third 
  times 
  longer 
  than 
  the 
  fourth, 
  and 
  the 
  fourth 
  nearly 
  that 
  many 
  

   times 
  longer 
  than 
  the 
  fifth. 
  The 
  base 
  of 
  the 
  sixth 
  segment 
  is 
  one-sixth 
  to 
  

   two-thirteenths 
  the 
  length 
  of 
  the 
  third, 
  and 
  the 
  tip 
  of 
  the 
  sixth 
  is 
  only 
  very 
  

   slightly 
  less 
  than 
  the 
  length 
  of 
  the 
  third 
  segment 
  (for 
  instance 
  eleventh-twelfths 
  

   of 
  that 
  length). 
  The 
  capitate 
  hairs 
  on 
  the 
  third 
  segment 
  reach 
  four-fifths 
  to 
  

   three-fifths 
  the 
  diameter 
  of 
  the 
  proximal 
  part 
  of 
  the 
  segment. 
  Near 
  the 
  base 
  

   this 
  segment 
  has 
  6-12 
  secondary 
  sensoria. 
  The 
  cornicles 
  reach 
  two-ninths 
  to 
  

   one-fourth 
  the 
  length 
  of 
  the 
  body. 
  At 
  a 
  distance 
  of 
  one-third 
  from 
  the 
  end 
  they 
  

   are 
  swollen. 
  From 
  here 
  toward 
  the 
  base 
  they 
  first 
  become 
  narrow 
  and 
  then 
  

   at 
  the 
  very 
  base 
  they 
  widen 
  considerably. 
  In 
  front 
  of 
  the 
  flange 
  there 
  is 
  another 
  

   slight 
  (hardly 
  noticeable) 
  swelling. 
  No 
  sculpture 
  is 
  seen 
  on 
  the 
  walls 
  of 
  the 
  

   cornicles. 
  The 
  cauda 
  is 
  two 
  to 
  two 
  and 
  one-half 
  times 
  shorter 
  than 
  the 
  cor-
