  and 
  with 
  darker 
  basal 
  areas) 
  more 
  like 
  that 
  of 
  the 
  rare 
  

   Z. 
  Chrysantas, 
  Trim. 
  A 
  singular 
  difference 
  between 
  the 
  

   two 
  forms 
  is 
  exhibited 
  in 
  the 
  cilia, 
  the 
  conspicuous 
  

   white 
  interruptions 
  of 
  which 
  in 
  Oreas 
  are 
  at 
  the 
  ex- 
  

   tremity 
  of 
  the 
  nervules, 
  while 
  in 
  Chrysantas 
  — 
  as 
  well 
  as 
  

   in 
  all 
  others 
  of 
  the 
  genus 
  known 
  to 
  me 
  in 
  which 
  this 
  

   character 
  occurs 
  — 
  they 
  are 
  inter-nervular. 
  In 
  the 
  

   structural 
  features 
  of 
  the 
  antennae 
  and 
  palpi, 
  and 
  in 
  the 
  

   shape 
  of 
  the 
  wings, 
  Oreas 
  also 
  agrees 
  with 
  Chrysantas. 
  

   The 
  under 
  side 
  is, 
  as 
  regards 
  the 
  hind 
  wings, 
  quite 
  

   unique 
  in 
  pattern 
  and 
  marking, 
  though 
  the 
  ^-shaped 
  

   hind-marginal 
  liturse 
  which 
  it 
  (in 
  common 
  with 
  the 
  apex 
  

   of 
  the 
  fore 
  wings) 
  presents 
  remind 
  one 
  of 
  the 
  similar 
  

   (but 
  reversed 
  and 
  much 
  brighter 
  silvery) 
  markings 
  in 
  

   the 
  otherwise 
  wholly 
  different 
  Z. 
  Wallengrenii, 
  Trim. 
  

   The 
  total 
  absence 
  of 
  any 
  steely 
  or 
  brassy 
  centres 
  in 
  the 
  

   black 
  spots 
  of 
  both 
  wings 
  is 
  further 
  a 
  highly 
  peculiar 
  

   feature 
  in 
  the 
  under 
  side 
  of 
  Z. 
  Oreas. 
  

  

  The 
  discovery 
  of 
  this 
  notable 
  addition 
  to 
  the 
  genus 
  

   Zeritis 
  is 
  due 
  to 
  Mr. 
  J. 
  M. 
  Hutchinson, 
  who 
  thus 
  de- 
  

   scribes 
  how 
  he 
  met 
  with 
  the 
  insect 
  at 
  an 
  elevation 
  of 
  

   about 
  7000 
  ft. 
  in 
  the 
  Drakensberg 
  Mountains, 
  Natal,

  " 
  The 
  first 
  specimen 
  I 
  saw 
  I 
  failed 
  to 
  capture, 
  

   owing 
  to 
  my 
  net 
  becoming 
  disjointed 
  ; 
  and 
  for 
  a 
  week 
  or 
  

   ten 
  days 
  subsequently 
  I 
  searched 
  for 
  another 
  without 
  

   success. 
  But 
  hurrying 
  home 
  to 
  my 
  cave 
  from 
  a 
  thunder- 
  

   storm, 
  while 
  a 
  heavy 
  wind 
  was 
  blowing, 
  one 
  of 
  the 
  new 
  

   Zeritis 
  was 
  blown 
  against 
  my 
  leg, 
  and, 
  lighting 
  there, 
  

   was 
  soon 
  boxed. 
  In 
  less 
  than 
  five 
  minutes 
  I 
  had 
  taken 
  

   eight, 
  including 
  a 
  pair 
  in 
  copula. 
  The 
  insect 
  was 
  very 
  

   local, 
  not 
  occurring 
  over 
  more 
  than 
  two 
  or 
  three 
  acres 
  of 
  

   ground. 
  Its 
  flight 
  is 
  near 
  the 
  ground, 
  but 
  very 
  rapid 
  

   and 
  very 
  suddenly 
  interrupted. 
  Unless 
  one 
  rose, 
  — 
  when 
  

   five 
  or 
  six 
  others 
  would 
  join 
  in 
  the 
  flight, 
  — 
  they 
  sat 
  very 
  

   close, 
  and 
  even 
  sweeping 
  the 
  net 
  over 
  them 
  would 
  not 
  

   make 
  them 
  rise. 
  I 
  took 
  eighteen 
  specimens."
