  The 
  only 
  Lepidoptoroiis 
  insect 
  worthy 
  of 
  special 
  notice 
  is 
  a 
  species 
  

   of 
  Moth 
  of 
  the 
  family 
  Litliosiida3 
  ; 
  this 
  moth 
  is 
  very 
  distinct 
  from 
  

   any 
  species 
  of 
  the 
  genus 
  hitherto 
  descrihed, 
  being 
  unusually 
  free 
  

   from 
  the 
  beautiful 
  spotting 
  peculiar 
  to 
  the 
  group. 
  

  

  Deiopeia 
  lactea. 
  

  

  Primaries 
  above 
  cream-coloured, 
  in 
  the 
  female 
  with 
  two 
  black 
  

   dots, 
  one 
  above 
  the 
  other, 
  upon 
  the 
  discocellular 
  veinlet 
  ; 
  a 
  marginal 
  

   series 
  of 
  black 
  spots, 
  the 
  largest 
  of 
  which 
  is 
  placed 
  at 
  the 
  apex 
  ; 
  a 
  

   greyish 
  indication 
  of 
  an 
  irregular 
  discal 
  belt 
  seen 
  through 
  the 
  wing. 
  

   Secondaries 
  pure 
  pearly 
  snow-white, 
  the 
  apex 
  broadly 
  black 
  from 
  

   costal 
  margin 
  to 
  third 
  median 
  branch, 
  with 
  a 
  conical 
  white 
  spot 
  at 
  

   the 
  apex 
  ; 
  two 
  small 
  depressed 
  black 
  marginal 
  spots 
  upon 
  the 
  median 
  

   interspaces 
  ; 
  an 
  extremely 
  slender 
  sordid 
  brownish 
  marginal 
  line 
  

   between 
  the 
  black 
  spots 
  and 
  the 
  anal 
  angle. 
  Thorax 
  cream-coloured, 
  

   with 
  the 
  usual 
  black 
  dots 
  — 
  that 
  is 
  to 
  say, 
  two 
  on 
  the 
  collar 
  and 
  two 
  

   on 
  each 
  tegula 
  ; 
  a 
  spot 
  of 
  pale 
  ochreous 
  on 
  each 
  shoulder. 
  Abdomen 
  

   pure 
  white. 
  Under 
  surface 
  pure 
  white 
  : 
  the 
  primaries 
  slightly 
  tinted 
  

   with 
  cream-colour, 
  strongly 
  so 
  on 
  the 
  costal 
  border 
  ; 
  a 
  more 
  or 
  less 
  

   interrupted, 
  externally 
  irregularly 
  dentated 
  black 
  band 
  across 
  the 
  

   disk, 
  commencing 
  upon 
  the 
  subcostal 
  vein, 
  and 
  terminating 
  in 
  a 
  

   more 
  or 
  less 
  distinct 
  furca 
  near 
  the 
  external 
  angle 
  ; 
  a 
  more 
  or 
  lesa 
  

   complete 
  marginal 
  series 
  of 
  black 
  spots 
  as 
  above, 
  and, 
  in 
  the 
  female, 
  

   a 
  black 
  augulated 
  bar 
  across 
  the 
  end 
  of 
  the 
  cell 
  upon 
  the 
  disco- 
  

   cellular 
  veinlet 
  ; 
  two 
  or 
  three 
  obliquely-placed 
  rose-red 
  subapical 
  

   spots 
  : 
  secondaries 
  with 
  a 
  black 
  spot 
  at 
  apex, 
  an 
  irregular 
  black 
  

   subapical 
  oblique 
  band, 
  and 
  from 
  one 
  to 
  four 
  marginal 
  spots. 
  Pectus 
  

   slightly 
  cream-tinted, 
  with 
  one 
  or 
  two 
  minute 
  lateral 
  black 
  dots. 
  

   Proboscis 
  pale 
  ochreous. 
  Anterior 
  tibise 
  and 
  tarsi 
  fuliginous 
  grey 
  

   in 
  front. 
  Venter 
  with 
  pale 
  ochre-tinted 
  anal 
  segment 
  ; 
  female 
  with 
  

   a 
  blackish 
  spot 
  on 
  each 
  side 
  of 
  the 
  opening. 
  Expanse 
  of 
  wings 
  

   37 
  millim. 
  

  

  One 
  pair, 
  Providence 
  Island 
  (Mascarenes), 
  April 
  1882. 
  

  

  The 
  entire 
  absence 
  of 
  the 
  usual 
  scarlet 
  markings 
  from 
  the 
  upper 
  

   surface 
  of 
  the 
  wings 
  in 
  this 
  species 
  renders 
  it 
  conspicuously 
  distinct 
  

   from 
  every 
  Deiopeia 
  hitherto 
  described 
  ; 
  it 
  bears 
  more 
  resemblance 
  

   to 
  pale 
  examples 
  of 
  D. 
  pura 
  (from 
  Guatemala) 
  than 
  to 
  any 
  other 
  

   species.
