  The 
  genus 
  Amphorophora 
  seems 
  to 
  be 
  world-wide 
  in 
  its 
  distribution. 
  

   From 
  data 
  at 
  hand 
  various 
  species 
  of 
  the 
  genus 
  are 
  found 
  in 
  North 
  

   America, 
  South 
  America, 
  Europe, 
  Africa, 
  India, 
  and 
  Japan. 
  

  

  Certain 
  groups 
  of 
  plants 
  are 
  favored 
  as 
  hosts. 
  The 
  genus 
  Rubus 
  

   has 
  eight 
  of 
  the 
  species 
  discussed 
  in 
  this 
  paper. 
  Ribes 
  has 
  four 
  

   species. 
  In 
  the 
  family 
  Ericaceae 
  the 
  genus 
  Vaccinium 
  has 
  one, 
  

   Gaultheria 
  one, 
  Epigoea 
  one, 
  Azalea 
  one, 
  and 
  Rhododendron 
  two 
  spe- 
  

   cies. 
  The 
  family 
  Compositae 
  is 
  host 
  to 
  five 
  species. 
  This 
  family 
  

   is 
  known 
  to 
  be 
  the 
  summer 
  host 
  of 
  one 
  of 
  these 
  five 
  and 
  will 
  probably 
  

   prove 
  to 
  be 
  the 
  same 
  for 
  the 
  others. 
  The 
  Coniferae 
  furnish 
  hosts 
  

   for 
  one 
  species 
  in 
  this 
  country 
  and 
  one 
  in 
  England. 
  

  

  There 
  are 
  practically 
  no 
  data 
  on 
  the 
  alternation 
  of 
  hosts 
  in 
  this 
  

   genus. 
  Only 
  one, 
  and 
  probably 
  two 
  species 
  are 
  known 
  to 
  have 
  alter- 
  

   nate 
  hosts. 
  Some 
  of 
  the 
  others 
  seem 
  to 
  live 
  on 
  the 
  same 
  plants 
  

   throughout 
  the 
  year. 
  

  

  Very 
  little 
  can 
  be 
  said 
  on 
  the 
  origin 
  and 
  phylogeny 
  of 
  the 
  group, 
  

   as 
  the 
  species 
  are 
  too 
  imperfectly 
  known 
  at 
  present. 
  I 
  am 
  not 
  

   in 
  a 
  position 
  to 
  say 
  where 
  the 
  genus 
  originated 
  or 
  on 
  what 
  plant. 
  

   In 
  fact, 
  I 
  can 
  not 
  be 
  absolutely 
  certain 
  that 
  I 
  am 
  dealing 
  with 
  a 
  

   phyllogenetic 
  group. 
  It 
  seems 
  probable 
  that 
  those 
  species 
  on 
  a 
  cer- 
  

   tain 
  hos£ 
  group 
  originated 
  from 
  a 
  common 
  ancestor, 
  as 
  they 
  seem 
  to 
  

   be 
  rather 
  closely 
  related. 
  

  

  In 
  the 
  group 
  of 
  forms 
  mentioned 
  as 
  living 
  on 
  Compositae 
  there 
  are 
  

   several 
  very 
  closely 
  related 
  ones. 
  These 
  include 
  cosmopolitana 
  

   (lactucae 
  Kaltenbach), 
  carduellinum 
  Theobald, 
  oleraceae 
  v. 
  d. 
  Goot, 
  

   formosana 
  Takahashi, 
  sonchifoliae 
  Takahashi. 
  There 
  are 
  also 
  some 
  

   other 
  specimens 
  in 
  the 
  National 
  Collection 
  which 
  could 
  be 
  described 
  

   as 
  new 
  species 
  with 
  about 
  as 
  much 
  difference 
  as 
  is 
  given 
  for 
  most 
  of 
  the 
  

   species 
  mentioned, 
  but 
  I 
  hesitate 
  to 
  do 
  this 
  until 
  more 
  is 
  known 
  of 
  

   them. 
  This 
  group 
  is 
  so 
  closely 
  related 
  that 
  it 
  is 
  often 
  difficult 
  to 
  

   place 
  an 
  individual 
  specimen. 
  There 
  should 
  be 
  extensive 
  rearings 
  

   to 
  settle 
  definitely 
  the 
  number 
  of 
  species 
  concerned. 
  Until 
  this 
  is 
  

   done 
  I 
  am 
  retaining 
  as 
  valid 
  species 
  those 
  which 
  have 
  been 
  described, 
  

   with 
  the 
  exception 
  of 
  sonchifoliae 
  Takahashi. 
  He 
  admits 
  that 
  it 
  is 
  

   very 
  near 
  oleraceae 
  v. 
  d. 
  Goot, 
  but 
  his 
  differences 
  do 
  not 
  hold 
  when 
  

   checked 
  against 
  metatype 
  specimens. 
  

  

  Certain 
  species 
  which 
  have 
  been 
  placed 
  in 
  this 
  genus 
  by 
  various 
  

   writers 
  are 
  not 
  included 
  here, 
  since 
  they 
  belong 
  to 
  the 
  group 
  men- 
  

   tioned 
  as 
  having 
  imbricated 
  antenna! 
  tubercles. 
  These 
  include 
  

   rhinanthi 
  Schouteden, 
  subterrans 
  Wilson, 
  magnoliae 
  Essig 
  and 
  

   Kuwana, 
  lonicericola 
  Takahashi, 
  and 
  hydrangeae 
  Matsumura. 
  

  

  Other 
  species 
  properly 
  belonging 
  to 
  Megoura 
  have 
  been 
  placed 
  in 
  

   Amphorophora 
  at 
  times 
  and 
  there 
  is 
  some 
  evidence 
  for 
  considering 
  

   Megoura 
  as 
  a 
  synonym 
  of 
  Amphorophora. 
  However, 
  I 
  have 
  decided 
  

   to 
  retain 
  it 
  as 
  a 
  valid 
  genus, 
  separating 
  the 
  two 
  on 
  the 
  shape 
  of 
  the
