  Mr. 
  William 
  F. 
  Kir 
  by 
  on 
  the 
  

  

  The 
  genus 
  XanthosjnlojJteryx 
  was 
  founded 
  by 
  Wallen- 
  

   gren 
  in 
  1858, 
  in 
  the 
  * 
  (Efversigt 
  ' 
  of 
  the 
  Swedish 
  Academy 
  

   (p. 
  83). 
  The 
  typical 
  species 
  was 
  Noctiia 
  Geryon, 
  of 
  

   Fabricius, 
  but 
  several 
  species 
  were 
  at 
  that 
  time 
  included 
  

   under 
  the 
  names 
  of 
  Geryon, 
  Fab., 
  or 
  Eiqjhemia, 
  Stoll 
  ; 
  

   and 
  as 
  the 
  actual 
  species 
  on 
  which 
  Wallengren 
  founded 
  

   his 
  genus 
  proved 
  to 
  be 
  Eusemia 
  superha, 
  ButL, 
  the 
  latter 
  

   becomes 
  the 
  true 
  type. 
  

  

  Hitherto 
  the 
  species 
  of 
  Xanthospilopteryx 
  have 
  usually 
  

   been 
  included 
  in 
  the 
  East 
  Indian 
  genus 
  Eusemia, 
  Dalm.* 
  

   {Episteme, 
  Hiibn.), 
  but 
  the 
  section 
  represented 
  by 
  

   Eusemia 
  Euphemia, 
  auct., 
  is 
  exclusively 
  confined 
  to 
  

   Tropical 
  and 
  Subtropical 
  Africa, 
  from 
  Abyssinia 
  to 
  

   Caffraria 
  and 
  Natal. 
  The 
  presence 
  of 
  an 
  accessory 
  cell 
  

   in 
  the 
  fore 
  wings, 
  and 
  the 
  shorter 
  and 
  thicker 
  legs, 
  the 
  

   shorter 
  claws, 
  unexpanded 
  tarsal 
  joints, 
  &c., 
  amply 
  

   justify 
  the 
  separation 
  of 
  Xanthospilojiteryx 
  from 
  Episteme. 
  

   There 
  are 
  other 
  species 
  from 
  Africa, 
  and 
  more 
  especi- 
  

   ally 
  Madagascar, 
  described 
  under 
  Eusemia, 
  which 
  do 
  

   not 
  belong 
  to 
  Xanthospilopteryx, 
  most 
  of 
  which 
  belong 
  

   to 
  Prof. 
  Westwood's 
  genus 
  Rothia 
  ; 
  these 
  I 
  do 
  not 
  

   intend 
  to 
  discuss 
  at 
  present. 
  No 
  true 
  Xanthospilopteryx 
  

   appears 
  to 
  inhabit 
  Madagascar, 
  

  

  The 
  British 
  Museum 
  is 
  very 
  rich 
  in 
  species 
  of 
  this 
  

   genus, 
  which 
  my 
  friend 
  and 
  colleague 
  Mr. 
  Butler 
  has 
  

   just 
  rearranged. 
  The 
  total 
  number 
  of 
  species 
  on 
  our 
  

   lists 
  (including 
  one 
  or 
  two 
  doubtfully 
  belonging 
  to 
  

   Xanthospilopteryx, 
  and 
  two 
  new 
  species 
  described 
  below) 
  

   is 
  25, 
  of 
  which 
  the 
  Museum 
  possesses 
  no 
  less 
  than 
  18. 
  

   Mr. 
  Butler 
  therefore 
  agreed 
  with 
  me 
  that 
  it 
  would 
  be 
  

   useful 
  to 
  give 
  a 
  short 
  sketch 
  of 
  the 
  species, 
  most 
  of 
  

   which 
  are 
  described 
  by 
  English 
  authors, 
  and 
  seem 
  very 
  

   little 
  known 
  abroad, 
  as 
  Mabille, 
  in 
  a 
  paper 
  on 
  the 
  subject 
  

   in 
  the 
  ' 
  Annales 
  de 
  la 
  Soc. 
  Ent. 
  de 
  France' 
  (6), 
  x., 
  Bull., 
  

   pp. 
  cxxii 
  — 
  cxxiv, 
  has 
  just 
  stated 
  that 
  he 
  is 
  only 
  acquainted 
  

   with 
  8 
  species 
  of 
  the 
  group, 
  4 
  of 
  which 
  he 
  describes 
  as 
  

   new 
  ; 
  and 
  that 
  he 
  has 
  only 
  been 
  able 
  to 
  find 
  descriptions 
  

   of 
  5 
  species 
  already 
  described, 
  one 
  of 
  which 
  {Eusemia 
  

   contigua, 
  Walk.) 
  is 
  unknown 
  to 
  him. 
  

  

  The 
  sjpecies 
  of 
  Xanthospilopteryx- 
  are 
  handsome 
  moths, 
  

   measuring 
  from 
  Ij 
  to 
  85 
  in. 
  in 
  expanse, 
  according 
  to 
  

   the 
  species. 
  The 
  fore 
  wingst 
  are 
  usually 
  longer 
  than
