  More 
  than 
  a 
  century 
  ago 
  (in 
  1770), 
  Drnry, 
  in 
  the 
  first 
  vol- 
  

   ume 
  of 
  his 
  admirable 
  work 
  cited 
  above, 
  illustrates 
  a 
  laro- 
  e 
  and 
  

   beautiful 
  Homoptera 
  from 
  examples 
  received 
  from 
  Virginia 
  

   and 
  Carolina, 
  to 
  which,-in 
  the 
  appendix 
  to 
  the 
  second 
  volume 
  

   he 
  applies 
  the 
  name 
  of 
  Phalcena 
  {Noctua) 
  lunata. 
  In 
  the 
  

   second 
  volume 
  (in 
  1773), 
  he 
  describes 
  and 
  figures 
  Phalcena 
  

   (Noctua) 
  edusa, 
  a 
  form 
  from 
  New 
  York, 
  differino- 
  from 
  the 
  

   preceding 
  in 
  having 
  the 
  subterminal 
  space 
  of 
  the 
  brown 
  wings 
  

   of 
  a 
  grayish 
  or 
  bluish 
  white, 
  which, 
  on 
  the 
  superiors, 
  is 
  gath- 
  

   ered 
  in 
  two 
  lunulated 
  spots. 
  

  

  From 
  their 
  wide 
  distribution 
  through 
  several 
  of 
  (he 
  United 
  

   States, 
  their 
  comparative 
  abundance 
  and 
  their 
  marked 
  beautv 
  

   these 
  two 
  forms 
  have 
  found 
  place 
  in 
  nearly 
  every 
  one 
  of 
  our 
  

   collections 
  of 
  Lepidoptera, 
  under 
  the 
  above 
  names, 
  and 
  not 
  

   infrequently 
  associated 
  with 
  their 
  presumed 
  companions 
  of 
  

   the 
  opposite 
  sex. 
  Very 
  recently, 
  the 
  interesting 
  discovery 
  

   has 
  been 
  made 
  that 
  the 
  two 
  constitute 
  but 
  a 
  single 
  species 
  

  

  I 
  was 
  led 
  to 
  suspect 
  the 
  above 
  relationship 
  two 
  years 
  ago 
  

   from 
  the 
  study 
  of 
  a 
  few 
  examples 
  in 
  my 
  collection, 
  and 
  accord- 
  

   ingly 
  requested 
  of 
  some 
  of 
  my 
  friends 
  the 
  careful 
  inspection 
  

   ot 
  their 
  future 
  captures, 
  with 
  a 
  view 
  of 
  determining 
  this 
  point. 
  

   Since 
  that 
  time 
  numerous 
  examples 
  of 
  the 
  two 
  forms 
  have 
  

   come 
  under 
  oar 
  observation, 
  in 
  all 
  of 
  which 
  the 
  females 
  are 
  

   lunata 
  and 
  all 
  the 
  males 
  "Edusa." 
  As 
  no 
  other 
  differences 
  

   except 
  sexual 
  are 
  perceptible, 
  beyond 
  the 
  colorational 
  features 
  

   there 
  is 
  no 
  longer 
  reason 
  for 
  questioning 
  the 
  identity 
  of 
  the
