  XV. 
  ON 
  CARADRLNA 
  FIDICULARIA 
  MORR. 
  

  

  This 
  species 
  was 
  described 
  as 
  Segetia 
  fidicularia 
  by 
  Mr. 
  

   Morrison, 
  in 
  Proc. 
  Bost. 
  Soc. 
  Nat. 
  Hist, 
  vol. 
  xvii, 
  p. 
  145. 
  

   In 
  the 
  Grote 
  Check 
  List 
  (No. 
  456) 
  this 
  name 
  is 
  recorded 
  as 
  a 
  

   synonym 
  of 
  Caradrina 
  fmullifera 
  Walker. 
  In 
  vol. 
  viii, 
  p. 
  

   188 
  of 
  the 
  Canadian 
  Entomologist, 
  Mr. 
  Grote 
  refers 
  the 
  species 
  

   to 
  the 
  European 
  C. 
  cubicularis 
  S. 
  V., 
  from 
  a 
  comparison 
  made 
  

   by 
  him, 
  with 
  a 
  male 
  example 
  of 
  the 
  latter, 
  noting 
  as 
  the 
  

   only 
  difference 
  between 
  the 
  American 
  and 
  the 
  European 
  forms, 
  

   that 
  the 
  latter 
  has 
  the 
  common 
  line 
  beneath 
  more 
  extended, 
  

   and 
  the 
  hind 
  wings 
  white. 
  

  

  With 
  four 
  examples 
  of 
  C. 
  fidicularia 
  before 
  me 
  (three 
  in 
  

   nearly 
  perfect 
  condition), 
  and 
  two 
  of 
  cubicularis, 
  I 
  am 
  com- 
  

   pelled 
  to 
  differ 
  from 
  the 
  reference 
  made 
  by 
  Mr. 
  Grote. 
  1 
  note 
  

   the 
  following 
  points 
  of 
  difference, 
  as 
  my 
  reasons 
  for 
  regarding 
  

   them 
  as 
  distinct. 
  

  

  While 
  in 
  0. 
  fidicularia 
  the 
  primaries 
  are 
  of 
  a 
  clear 
  gray, 
  in 
  

   cubicularis 
  they 
  are 
  of 
  a 
  peculiar 
  pale 
  brownish 
  shade, 
  diffi- 
  

   cult 
  to 
  designate, 
  bearing 
  what 
  might 
  be 
  called 
  an 
  amber 
  tint. 
  

   In 
  the 
  former, 
  the 
  intranervular 
  marginal 
  black 
  dots 
  are 
  more 
  

   conspicuous 
  than 
  in 
  the 
  latter, 
  and 
  its 
  subterminal 
  line 
  is 
  not 
  

   followed 
  by 
  whitish 
  ; 
  the 
  posterior 
  transverse 
  line 
  is 
  farther 
  

   removed 
  from 
  the 
  reniform 
  than 
  in 
  cubicularis. 
  O. 
  fidicu- 
  

   laria 
  has 
  a 
  well 
  marked 
  discal 
  dot, 
  which 
  the 
  other 
  has 
  not. 
  

   The 
  primaries 
  of 
  the 
  American 
  species 
  are 
  the 
  broader. 
  

  

  The 
  secondaries 
  of 
  fidicularia 
  are 
  of 
  a 
  fuscous 
  shade, 
  increas- 
  

   ing 
  in 
  depth 
  toward 
  the 
  margin 
  ; 
  in 
  the 
  other 
  they 
  are 
  white, 
  

   with 
  the 
  end 
  of 
  the 
  nervules 
  and 
  extreme 
  margin 
  tinted 
  with 
  

   ochraceous. 
  In 
  the 
  latter, 
  no 
  discal 
  spot 
  is 
  seen 
  from 
  above, 
  

   while 
  in 
  the 
  former 
  it 
  is 
  quite 
  conspicuous 
  — 
  the 
  heavily 
  

   marked 
  dot 
  of 
  the 
  lower 
  surface 
  showing 
  in 
  transparency. 
  

  

  G. 
  cubicularis 
  is 
  known 
  to 
  be 
  a 
  variable 
  form, 
  differing 
  

   greatly, 
  according 
  to 
  Guenee, 
  in 
  size, 
  depth 
  of 
  color, 
  and 
  

   intensity 
  of 
  designs, 
  having 
  been 
  described 
  under 
  the 
  sev- 
  

   eral 
  names 
  of 
  quadripunctata 
  Fabr.,
