  The 
  reference 
  of 
  X. 
  Thaxteri 
  as 
  a 
  variety 
  of 
  X. 
  lambda, 
  by 
  

   Dr. 
  Speyer, 
  has 
  been 
  noted 
  on 
  page

  From 
  the 
  examina- 
  

   tion 
  of 
  the 
  photograph 
  of 
  X. 
  Thaxteri 
  given 
  in 
  the 
  Grote 
  

   Check 
  List, 
  Pt. 
  ii, 
  fig. 
  3, 
  Dr. 
  Speyer 
  was 
  led 
  to 
  express 
  his 
  

   opinion* 
  that 
  it 
  was 
  bnt 
  a 
  variety 
  of 
  the 
  European 
  X. 
  lambda. 
  

   Mr. 
  Grote, 
  in 
  its 
  description 
  {Bui. 
  Buf. 
  Soc. 
  Nat. 
  Sei., 
  ii, 
  p. 
  

   196), 
  had 
  instituted 
  a 
  comparison 
  between 
  it 
  and 
  Zinckenii, 
  

   under 
  which 
  name 
  X. 
  lambda 
  was 
  formerly 
  known. 
  

  

  The 
  recent 
  examination 
  by 
  Dr. 
  Speyer 
  of 
  a 
  number 
  of 
  ex- 
  

   amples 
  of 
  X. 
  Thaxteri 
  has 
  confirmed 
  the 
  opinion 
  above 
  

   expressed. 
  He 
  finds 
  it 
  to 
  " 
  correspond 
  with 
  the 
  European 
  

   species 
  in 
  all 
  particulars 
  except 
  in 
  that 
  its 
  primaries 
  are 
  a 
  

   little 
  broader, 
  and 
  its 
  secondaries 
  somewhat 
  more 
  excavated 
  

   on 
  vein 
  5. 
  X. 
  lambda 
  had 
  heretofore 
  been 
  known 
  under 
  three 
  

   varieties 
  ; 
  Zinckenii 
  Treits., 
  rufescens 
  Men., 
  and 
  somni- 
  

   culosa 
  Hering. 
  Thaxteri 
  is 
  now 
  the 
  fourth 
  well 
  marked 
  

   variety 
  ; 
  in 
  its 
  sharp 
  markings, 
  it 
  resembles 
  ZincJcenii 
  var., 
  

   and 
  in 
  its 
  color, 
  rufescens 
  var."

  In 
  Harris' 
  Report 
  on 
  the 
  Insects 
  of 
  Massachusetts, 
  p. 
  345 
  

   (Edition 
  of 
  1841), 
  the 
  aathor, 
  after 
  describing 
  some 
  caterpil- 
  

   lars 
  infesting 
  the 
  hop-vine, 
  says 
  of 
  the 
  moths 
  proceeding 
  

   from 
  them, 
  that 
  "they 
  have 
  been 
  named 
  [by 
  him] 
  the 
  Hypena 
  

   humuli, 
  on 
  the 
  supposition 
  that 
  they 
  are 
  distinct 
  from 
  the 
  

   Hypena 
  rostralis 
  or 
  hop-vine 
  snout-moth 
  of 
  Europe." 
  

  

  "These 
  moths 
  are 
  readily 
  known 
  by 
  their 
  long, 
  wide, 
  and 
  

   flattened 
  feelers, 
  which 
  are 
  held 
  close 
  together, 
  and 
  project 
  

   horizontally 
  from 
  the 
  fore 
  part 
  of 
  the 
  head 
  in 
  the 
  manner 
  of 
  

   a 
  snout. 
  The 
  antennae 
  in 
  both 
  sexes 
  are 
  naked 
  and 
  bristle- 
  

   formed. 
  The 
  wings 
  vary 
  in 
  color, 
  being 
  sometimes 
  dusky 
  or 
  

   blackish 
  brown, 
  and 
  sometimes 
  of 
  a 
  much 
  lighter 
  rusty 
  brown 
  

   color. 
  The 
  fore- 
  wings 
  are 
  marbled 
  with 
  gray 
  beyond 
  the 
  

   middle, 
  and 
  have 
  a 
  distinct 
  oblique 
  gray 
  spot 
  on 
  the 
  tip 
  ; 
  they 
  

   are 
  crossed 
  by 
  two 
  wavy 
  blackish 
  lines, 
  one 
  near 
  the 
  middle, 
  

   and 
  the 
  other 
  near 
  the 
  outer 
  hind 
  margin 
  ; 
  these 
  lines 
  are 
  

   formed 
  by 
  little 
  elevated 
  black 
  tufts, 
  and 
  there 
  are 
  also 
  two 
  

   similar 
  tufts 
  on 
  the 
  middle 
  of 
  the 
  wing. 
  The 
  hind 
  wings 
  are 
  

   dusky 
  brown 
  or 
  light 
  brown, 
  with 
  a 
  paler 
  fringe, 
  and 
  are 
  

   without 
  bands 
  or 
  spots. 
  The 
  wings 
  expand 
  about 
  one 
  inch 
  

   and 
  a 
  quarter."
