  Takahashi 
  discusses 
  this 
  form 
  without 
  giving 
  it 
  a 
  name, 
  simply 
  

   calling 
  it 
  Amphorophora, 
  species. 
  While 
  I 
  have 
  not 
  seen 
  it, 
  I 
  do 
  not 
  

   recognize 
  it 
  from 
  his 
  description 
  as 
  belonging 
  to 
  any 
  of 
  the 
  named 
  

   species 
  in 
  this 
  genus. 
  It 
  is 
  evidently 
  a 
  border 
  line 
  species 
  between 
  

   Amphorophora 
  and 
  Macrosiphum. 
  I 
  take 
  pleasure 
  in 
  naming 
  it 
  

   after 
  Takahashi 
  and 
  quote 
  his 
  description.
