  with 
  teucrii. 
  He 
  says 
  that, 
  in 
  the 
  Roeslingberg, 
  loranus 
  only 
  occurs 
  

   without 
  any 
  transitional 
  forms 
  to 
  teucrii 
  ; 
  at 
  the 
  beginning 
  of 
  June, 
  

   1897, 
  the 
  insect 
  was 
  already 
  on 
  the 
  wing, 
  whilst 
  many 
  fresh 
  specimens 
  

   were 
  observed 
  between 
  the 
  beginning 
  of 
  July 
  and 
  the 
  20th 
  of 
  the 
  

   month, 
  amongst 
  them 
  a 
  couple 
  paired, 
  both 
  sexes 
  true 
  loranus 
  form, 
  in 
  

   1895." 
  He 
  adds: 
  " 
  I 
  found 
  at 
  the 
  same 
  place 
  a 
  fresh 
  $ 
  as 
  late 
  as 
  

   August 
  19th. 
  In 
  the 
  Lenning, 
  there 
  flies, 
  without 
  definite 
  transitional 
  

   forms 
  to 
  loranus, 
  round 
  Teucrium 
  scorodonia, 
  the 
  species 
  named 
  after 
  this 
  

   foodplant, 
  teucrii; 
  it 
  occurs 
  in 
  the 
  second 
  week 
  of 
  June, 
  and, 
  compared 
  

   with 
  loranus, 
  is 
  abundant, 
  and 
  continues 
  till 
  the 
  beginning 
  of 
  July, 
  never 
  

   later. 
  In 
  the 
  Heimbach 
  Valley, 
  where 
  I 
  discovered 
  loranus, 
  and 
  

   where 
  I 
  have 
  since 
  repeatedly 
  met 
  it, 
  although 
  never 
  so 
  abundantly 
  as 
  

   on 
  the 
  Roesling 
  mountain, 
  I 
  only 
  once, 
  on 
  May 
  31st, 
  1897, 
  captured 
  

   0. 
  teucrii, 
  a 
  fine 
  $ 
  , 
  flying 
  round 
  Teucrium 
  scorodonia. 
  The 
  two 
  

   insects 
  with 
  us 
  have 
  different 
  habitats, 
  which 
  can 
  only 
  be 
  attributed 
  

   to 
  different 
  foodplants, 
  but, 
  although 
  I 
  have 
  not 
  yet 
  found 
  the 
  larva 
  of 
  

   loranus, 
  I 
  am 
  satisfied 
  that 
  it 
  does 
  not 
  live 
  on 
  Teucrium. 
  On 
  the 
  Roesling 
  

   mountain 
  the 
  moths 
  are 
  always 
  found 
  flying 
  about 
  a 
  pretty 
  but 
  tiny 
  

   plant, 
  blooming 
  in 
  July, 
  that 
  I 
  have 
  been 
  unable 
  to 
  determine, 
  but 
  

   which 
  certainly 
  is 
  not 
  Teucrium.'" 
  It 
  must 
  be 
  confessed 
  that 
  Fuchs' 
  

   argument 
  is 
  here 
  particularly 
  weak, 
  so 
  much 
  so 
  that 
  Staudinger 
  and 
  

   Rebel 
  have 
  no 
  hesitation 
  in 
  referring 
  loranus 
  to 
  teucrii 
  (Cat., 
  3rd 
  ed., 
  

   p. 
  71) 
  with 
  the 
  diagnosis 
  " 
  var. 
  minor, 
  obscurior, 
  magis 
  grisea.

   west

  — 
  This 
  stands, 
  according 
  to 
  Hoffmann, 
  next 
  to 
  obseurus, 
  Z., 
  on 
  account 
  

   of 
  the 
  white 
  longitudinal 
  dash 
  in 
  the 
  outer 
  marginal 
  fringes 
  of 
  the 
  lower 
  lobe, 
  and 
  

   of 
  the 
  nearly 
  equal 
  length 
  of 
  the 
  black 
  scaling 
  on 
  each 
  side 
  of 
  the 
  apex 
  of 
  the 
  third 
  

   plumule 
  of 
  the 
  hind 
  wing; 
  it 
  is, 
  however, 
  usually 
  larger, 
  and 
  of 
  a 
  darker, 
  more 
  coffee- 
  

   or 
  yellow-brown, 
  ground 
  colour, 
  while 
  obseurus, 
  Z., 
  has 
  a 
  red-brown 
  coloration, 
  

   which, 
  in 
  viewing 
  a 
  number 
  of 
  specimens, 
  very 
  easily 
  catches 
  the 
  eye. 
  The 
  white 
  

   markings 
  on 
  both 
  lobes 
  of 
  the 
  forewings 
  are 
  broader 
  and 
  more 
  shining 
  than 
  in 
  

   obseurus, 
  Z., 
  also 
  the 
  disc 
  of 
  the 
  wing 
  carries 
  several 
  white 
  dots, 
  which 
  are 
  wanting 
  

   in 
  the 
  latter, 
  so 
  that 
  var. 
  eeleusi 
  appears 
  much 
  more 
  variegated. 
  The 
  palpi 
  in 
  var. 
  

   celeusi 
  are, 
  in 
  18 
  specimens 
  bred 
  here 
  and 
  quite 
  perfect, 
  more 
  slender 
  and 
  rounder, 
  

   mostly 
  somewhat 
  curved 
  upwards 
  with 
  slightly 
  drooping 
  terminal 
  joints 
  ; 
  the 
  2nd 
  

   joint 
  is 
  outwardly 
  brown 
  with 
  two, 
  more 
  or 
  less 
  large, 
  white 
  spots, 
  and 
  has 
  no 
  

   porrected 
  tuft 
  of 
  hairs 
  at 
  the 
  extremity 
  ; 
  the 
  3rd 
  joint 
  is 
  white, 
  with 
  a 
  pair 
  of 
  fine 
  

   brown 
  spots, 
  or 
  brown 
  with 
  white 
  spots 
  ; 
  in 
  several 
  specimens 
  the 
  palpi, 
  outwardly, 
  

   are 
  almost 
  entirely 
  white. 
  On 
  the 
  inner 
  side 
  the 
  palpi 
  are 
  marked 
  just 
  as 
  on 
  the

  The 
  pilosellae-hieracii 
  group 
  is 
  one 
  of 
  the 
  most 
  difficult 
  amongst 
  the 
  plumes, 
  

   and 
  one 
  suspects 
  that 
  too 
  many 
  species 
  have 
  been 
  described 
  therein. 
  This 
  doubt 
  

   was 
  impressed 
  on 
  me 
  when 
  I 
  read, 
  in 
  Stainton's 
  Ent. 
  Annual 
  for 
  1870, 
  the 
  description 
  

   of 
  a 
  new 
  species, 
  teucrii 
  (Greening), 
  Jordan. 
  This 
  doubt 
  was 
  increased 
  when 
  I 
  

   received 
  from 
  Zeller 
  two 
  specimens 
  of 
  this 
  new 
  English 
  species 
  (probably 
  from 
  

   Jordan). 
  The 
  larvae 
  of 
  this, 
  I 
  learned 
  from 
  Regensburg, 
  had 
  been 
  reared 
  on 
  

   Teucrium 
  scorodonia. 
  A 
  few 
  years 
  ago, 
  Schmid 
  found 
  a 
  larva 
  on 
  Teucrium 
  

   chamaedrys, 
  near 
  Kelheim, 
  that 
  produced 
  an 
  Oxyptilus, 
  which 
  the 
  discoverer, 
  

   thinking 
  he 
  had 
  a 
  new 
  species, 
  called 
  0. 
  celeusi. 
  As 
  a 
  result 
  of 
  many 
  years' 
  

   collecting 
  1 
  possess 
  a 
  very 
  large 
  number 
  of 
  specimens 
  belonging 
  to 
  the 
  pilosellae- 
  

   hieracii 
  group 
  from 
  different 
  countries, 
  and 
  I 
  have 
  become 
  very 
  doubtful 
  as 
  at 
  the 
  

   specific 
  difference 
  of 
  hieracii 
  and 
  pilosellae. 
  0. 
  teucrii, 
  Jord., 
  and 
  0. 
  celeusi, 
  I 
  

   unhesitatingly 
  conclude 
  to 
  be 
  dark 
  forms 
  of 
  hieracii 
  ; 
  two 
  specimens, 
  received 
  years 
  

   ago 
  from 
  Glitz, 
  of 
  Hanover, 
  completely 
  agree 
  with 
  the 
  specimens 
  from 
  England 
  

   and 
  Kelheim, 
  etc. 
  (Frev).
