  Anorthosia 
  straminis,

  Ypsolnpkus 
  straminis, 
  Wlsm., 
  Trans. 
  Ent. 
  Soc. 
  Lond., 
  

   1881, 
  266. 
  

  

  Grahamstown 
  (Cape 
  Colony), 
  one 
  specimen 
  {Druce) 
  ; 
  

   Delagoa 
  Bay 
  (East 
  Africa), 
  one 
  specimen 
  {Druce). 
  

  

  This 
  species 
  only 
  differs 
  from 
  Anorthosia 
  punctiferella, 
  

   Clem., 
  the 
  type 
  of 
  the 
  genus, 
  by 
  having 
  11 
  veins 
  in 
  the 
  

   fore 
  wings 
  (7 
  and 
  8 
  being 
  coincident) 
  instead 
  of 
  12 
  veins, 
  

   7 
  and 
  8 
  from 
  a 
  common 
  stem. 
  

  

  In 
  my 
  former 
  paper 
  I 
  had 
  placed 
  it 
  in 
  the 
  genus 
  

   Ysolophas, 
  which 
  has 
  the 
  same 
  neuration 
  as 
  Anortliosia, 
  

   but 
  the 
  form 
  of 
  the 
  palpi 
  agrees 
  far 
  more 
  closely 
  with 
  

   the 
  latter 
  genus. 
  The 
  neural 
  characters 
  of 
  Anortliosia, 
  

   as 
  figured 
  in 
  Stainton's 
  edition 
  of 
  Clemens' 
  papers 
  

   (Tin. 
  N. 
  Am., 
  p. 
  Ill), 
  is 
  not 
  precisely 
  correct; 
  veins 
  3 
  

   and 
  4 
  of 
  the 
  hind 
  wings 
  should 
  be 
  separated 
  at 
  the 
  base, 
  

   and 
  the 
  discal 
  cell 
  of 
  both 
  wings 
  is 
  closed, 
  as 
  in 
  other 
  

   allied 
  genera.

  whitish, 
  annulated 
  with 
  brown. 
  Palpi 
  : 
  second 
  

   joint 
  thickly 
  clothed 
  with 
  projecting 
  scales 
  taking 
  a 
  triangular 
  

   form 
  ; 
  externally 
  brown, 
  fringed 
  with 
  whitish 
  at 
  its 
  anterior 
  edge, 
  

   internally 
  whitish 
  throughout 
  ; 
  apical 
  joint 
  very 
  long, 
  slender, 
  

   erect, 
  slightly 
  recurved, 
  whitish, 
  springing 
  from 
  the 
  apex 
  of 
  the 
  

   triangular 
  tuft 
  of 
  scales, 
  not, 
  as 
  is 
  usual 
  in 
  Ypsolophus, 
  fi'om 
  the 
  

   base 
  ; 
  in 
  this 
  respect 
  it 
  agrees 
  aiDproximately 
  with 
  Anortliosia, 
  

   Clem., 
  rather 
  than 
  with 
  Yjysolojjhus, 
  in 
  which 
  I 
  was 
  at 
  first 
  

   inclined 
  to 
  place 
  it, 
  although 
  differing 
  somewhat 
  from 
  both 
  in 
  the 
  

   form 
  of 
  the 
  apical 
  joint.

  with 
  a

  before 
  the

   apex,

  is 
  rather

  followed 
  by 
  a 
  few 
  brown 
  scales 
  on 
  the

  part 
  of 
  the 
  

   margin 
  near 
  the

  third 
  of 
  the

   brown 
  narrow 
  hue-like 
  spot 
  along 
  the 
  extreme 
  costal

   scarcely 
  beyond
