  is 
  the 
  type 
  of 
  the 
  species. 
  The 
  special 
  feature 
  of 
  this 
  form 
  lies 
  in 
  

   the 
  radiating 
  lines 
  running 
  from 
  the 
  base, 
  or 
  near 
  it, 
  across 
  the 
  disc 
  

   of 
  the 
  forewing 
  and 
  ending 
  in 
  the 
  costa, 
  apex, 
  or 
  termen. 
  The 
  

   ground 
  colour 
  is 
  usually 
  ochreous 
  of 
  a 
  paler 
  or 
  darker 
  shade, 
  but 
  

   the 
  colour 
  of 
  the 
  rays 
  varies 
  much. 
  They 
  may 
  be 
  dark 
  ochreous, 
  

   dark 
  brown, 
  red 
  brown 
  or 
  fuscous. 
  In 
  some 
  specimens 
  the 
  rays 
  are 
  

   mere 
  lines 
  little 
  darker 
  than 
  the 
  ground 
  colour 
  while 
  in 
  the 
  opposite 
  

   extreme 
  they 
  are 
  broad 
  solid 
  bands, 
  leaving 
  only 
  thin 
  streaks 
  of 
  

   ground 
  colour 
  between 
  them. 
  Among 
  the 
  rays 
  one 
  may 
  generally 
  

   be 
  traced 
  extending- 
  from 
  the 
  base 
  to 
  the 
  apex. 
  This 
  is 
  the. 
  most 
  

   persistent 
  and 
  is 
  the 
  ray 
  which 
  alone 
  survives 
  in 
  ab. 
  fissella. 
  

  

  Ab. 
  bi/sinella,

  Samm."

  Forewings 
  whitish 
  with 
  a 
  dark 
  ochreous 
  median 
  ray, 
  costa 
  and 
  

   dorsum 
  broadly 
  ochreous. 
  The 
  whitish 
  ground 
  colour 
  is 
  thus 
  split 
  

   up 
  into 
  a 
  fine 
  pale 
  subcostal 
  ray 
  and 
  two 
  broader 
  pale 
  rays, 
  the 
  one 
  

   above 
  and 
  the 
  other 
  below 
  the 
  dark 
  median 
  ray. 
  Mr. 
  Durrant 
  

   kindly 
  showed 
  me 
  one 
  nearly 
  typical 
  example 
  from 
  France 
  and 
  

   others 
  belonging 
  to 
  this 
  form, 
  but 
  with 
  brown 
  or 
  reddish 
  rays, 
  from 
  

   England. 
  Bijainella 
  differs 
  from 
  typical 
  radiatella 
  in 
  having 
  only 
  

   about 
  three 
  pale 
  rays 
  whereas 
  that 
  has 
  alternate 
  pale 
  and 
  dark 
  rays.

  This 
  is 
  the 
  form 
  with 
  a 
  broad 
  dark 
  streak 
  running 
  through 
  the 
  

   middle 
  of 
  the 
  forewing 
  from 
  the 
  base 
  to 
  the 
  apox, 
  thus 
  dividing 
  the 
  

   wing 
  into 
  two 
  parts. 
  Huebner's 
  figure 
  shows 
  a 
  whitish 
  example 
  

   with 
  a 
  broad 
  blackish 
  median 
  ray. 
  The 
  more 
  handsome 
  specimens 
  

   show 
  a 
  uniform 
  white 
  or 
  pale 
  ochreous 
  ground 
  colour 
  and 
  a 
  deep 
  

   red-brown 
  stripe. 
  The 
  ground 
  colour 
  varies 
  through 
  ochreous, 
  

   reddish-brown 
  to 
  fuscous, 
  and 
  the 
  stripe 
  from 
  red 
  -brown 
  to 
  blackish 
  

   grey. 
  The 
  paler 
  portion 
  of 
  the 
  wing 
  is 
  sometimes 
  mottled 
  as 
  in 
  

   ab. 
  variella.

  Forewings 
  dark, 
  uniformly 
  covered 
  with 
  short 
  pale 
  longitudinal 
  

   strigulae. 
  This 
  is 
  probably 
  an 
  extreme 
  development 
  of 
  one 
  of 
  the 
  

   directions 
  of 
  radiatella 
  in 
  which 
  the 
  rays 
  are 
  broken 
  up 
  into 
  short 
  

   lengths 
  instead 
  of 
  being 
  continuous. 
  The 
  general 
  appearance 
  of 
  

   aspinsa 
  is 
  so 
  distinct 
  from 
  the 
  other 
  aberrations 
  that 
  I 
  think 
  it 
  ought 
  

   to 
  bear 
  a 
  name. 
  My 
  specimen 
  (ex. 
  Sam 
  Steven's 
  coll.) 
  is 
  red-brown 
  

   thickly 
  sprinkled 
  with 
  short 
  ochreous 
  grey 
  streaks.

  " 
  Forewings 
  uniform 
  ochreous 
  brown 
  or 
  light 
  nut 
  brown." 
  

   Treitschke 
  adds 
  to 
  this 
  description 
  that 
  sometimes 
  there 
  is 
  also 
  a 
  

   dark 
  median 
  streak 
  and 
  a 
  black 
  dot 
  before 
  the 
  hind 
  margin. 
  He 
  

   seems 
  to 
  have 
  been 
  under 
  the 
  impression 
  that 
  he 
  had 
  the 
  HnitcUa 
  

   of 
  Huebner 
  before 
  him. 
  This 
  is 
  an 
  OecnpJwra. 
  Later 
  (vol. 
  10, 
  part 
  

   3, 
  p. 
  187.) 
  he 
  recognises 
  the 
  moth 
  as 
  a 
  variety 
  of 
  Ihnelia, 
  and 
  after 
  

   describing 
  the 
  latter 
  he 
  says 
  " 
  very 
  seldom 
  the 
  median 
  streak 
  is 
  

   absent 
  and 
  all 
  the 
  wing 
  is 
  ochreous 
  with 
  the 
  discal 
  spot 
  very 
  faint, 
  

   thus 
  is 
  constituted 
  the 
  variety, 
  iinitella."
