  have 
  one 
  specimen 
  in 
  which 
  the 
  white 
  patch 
  is 
  extended 
  along 
  the 
  

   costa, 
  and 
  the 
  whole 
  of 
  the 
  dorsum 
  is 
  also 
  white, 
  while 
  an 
  ochreous 
  

   brown 
  streak 
  runs 
  along 
  the 
  centre 
  of 
  the 
  wing 
  from 
  base 
  to 
  apex. 
  

   This 
  is 
  a 
  parallel 
  form 
  to 
  ab. 
  fissella 
  of 
  H. 
  radiatdla. 
  Of 
  the 
  two 
  

   following 
  aberrations 
  I 
  have 
  not 
  seen 
  any 
  examples. 
  

  

  Ab. 
  iistidata, 
  Haw. 
  542. 
  Stephens. 
  

  

  Wings 
  whitish 
  with 
  various 
  reddish 
  ash 
  streaks, 
  cilia 
  umber 
  

   brown 
  but 
  fulvous 
  at 
  the 
  anal 
  angle. 
  

  

  Ab. 
  erminea, 
  Haw. 
  542. 
  Stephens. 
  

  

  Wings 
  white, 
  thickly 
  spotted 
  with 
  fuscous 
  or 
  black, 
  with 
  a 
  dark 
  

   spot 
  beyond 
  the 
  middle 
  and 
  a 
  short 
  golden 
  streak 
  from 
  the 
  base 
  to 
  

   the 
  middle. 
  

  

  Ab. 
  ochroleuca, 
  Haw. 
  542. 
  Sfceph. 
  

  

  Wings 
  ochreous 
  white 
  with 
  an 
  immaculate 
  oblong 
  white 
  patch 
  at 
  

   the 
  base. 
  This 
  is 
  an 
  albescent 
  almost 
  unicolorous 
  form. 
  I 
  have 
  

   two 
  worn 
  examples, 
  ex. 
  coll. 
  S. 
  Stevens. 
  It 
  is 
  parallel 
  to 
  ab. 
  

   flaviciliata 
  of 
  H. 
  radiatella. 
  

  

  It 
  will 
  be 
  seen 
  that 
  this 
  species 
  does 
  not 
  show 
  so 
  large 
  a 
  range 
  

   of 
  variation 
  as 
  H. 
  radiatella, 
  nevertheless 
  it 
  is 
  difficult 
  to 
  obtain 
  two 
  

   specimens 
  exactly 
  alike. 
  

  

  Ahehaea 
  si/lrella, 
  L., 
  " 
  Sys. 
  Nat." 
  ed. 
  xii.,

  Wood, 
  1541. 
  

  

  The 
  species 
  of 
  this 
  genus 
  show 
  very 
  little 
  variation 
  in 
  comparison 
  

   with 
  those 
  of 
  the 
  last. 
  The 
  present 
  species 
  varies 
  in 
  the 
  depth 
  of 
  

   colour 
  and 
  in 
  the 
  number 
  and 
  completeness 
  of 
  the 
  fasciae. 
  I 
  have 
  

   one 
  specimen 
  which 
  is 
  almost 
  unicolorous 
  as 
  the 
  fasciae 
  are 
  scarcely 
  

   traceable. 
  Normally 
  there 
  are 
  two 
  oblique 
  bands 
  on 
  the 
  forewing, 
  

   one 
  before 
  and 
  the 
  other 
  beyond 
  the 
  middle. 
  Some 
  examples 
  

   exhibit 
  a 
  third 
  fascia 
  lying 
  between 
  the 
  base 
  and 
  the 
  first 
  band 
  (as 
  I 
  

   call 
  it 
  for 
  convenience) 
  while 
  in 
  others 
  a 
  third 
  fascia 
  lies 
  between 
  the 
  

   second 
  band 
  and 
  the 
  hind 
  margin. 
  Wood's 
  figure 
  shows 
  a 
  specimen 
  

   bearing 
  all 
  the 
  four 
  fasciae, 
  I 
  have 
  mentioned, 
  and 
  also 
  an 
  additional 
  

   fascia 
  on 
  the 
  hind 
  margin. 
  This 
  last 
  I 
  have 
  never 
  seen 
  in 
  any 
  

   example. 
  

  

  Abebaea 
  alpella, 
  Schiff. 
  " 
  Verz." 
  135. 
  jyersicellus, 
  Steph. 
  Wood, 
  

   fig. 
  1536. 
  

  

  This 
  is 
  a 
  smaller 
  and 
  greyer 
  insect 
  than 
  sylvella 
  and 
  does 
  not 
  

   seem 
  to 
  vary 
  much. 
  Some 
  examples 
  are 
  more 
  ochreous 
  than 
  others 
  

   and 
  in 
  some 
  the 
  reticulations 
  of 
  the 
  forewing 
  are 
  more 
  strongly 
  

   expressed. 
  The 
  dorsal 
  fasciae 
  may 
  be 
  mere 
  spots 
  lying 
  on 
  the 
  

   margin 
  or 
  they 
  may 
  be 
  extended 
  upwards 
  beyond 
  the 
  fold. 
  At 
  one 
  

   time 
  it 
  was 
  a 
  belief, 
  especially 
  among 
  continental 
  collectors, 
  that 
  

   alpella 
  was 
  the 
  male 
  and 
  Uicella 
  the 
  female 
  of 
  one 
  and 
  the 
  same 
  

   species. 
  Of 
  alpella 
  I 
  have 
  both 
  sexes. 
  This 
  is 
  the 
  persicellus 
  of 
  

   Stephens 
  and 
  Wood 
  but 
  not 
  of 
  Schiffermiller. 
  That 
  species 
  is 
  a 
  

   sulphur, 
  yellow 
  insect 
  which 
  has 
  not 
  occurred 
  in 
  Britain.
