  Mr. 
  A. 
  R. 
  Wallace 
  on 
  the 
  Habits 
  of 
  the 
  

  

  Lower 
  Amazon, 
  while 
  immediately 
  opposite 
  to 
  it 
  is 
  found 
  an 
  allied 
  

   species, 
  the 
  C. 
  Leprieuril. 
  A 
  third 
  species 
  has 
  been 
  discovered 
  

   by 
  Mr. 
  Bates, 
  on 
  the 
  south 
  side 
  of 
  the 
  Upper 
  Amazon, 
  and 
  has 
  

   been 
  named 
  after 
  him 
  ; 
  while 
  a 
  fourth, 
  equally 
  beautiful, 
  which 
  I 
  

   found 
  near 
  the 
  sources 
  of 
  the 
  Rio 
  Negro, 
  was 
  lost 
  with 
  the 
  rest 
  of 
  

   my 
  collections 
  on 
  my 
  return 
  voyage, 
  and 
  so 
  remains 
  to 
  be 
  redis- 
  

   covered. 
  They 
  all 
  frequent 
  dry, 
  open 
  woods. 
  The 
  females 
  often 
  

   fly 
  low, 
  but 
  the 
  males 
  settle 
  on 
  the 
  leaves 
  of 
  lofty 
  trees, 
  and 
  are 
  

   very 
  difficult 
  to 
  capture. 
  The 
  C. 
  Leprieurn 
  was 
  found 
  plentifully 
  

   on 
  the 
  trunks 
  of 
  trees, 
  where 
  a 
  black 
  sap 
  was 
  exuding. 
  In 
  their 
  

   flight 
  they 
  much 
  resemble 
  the 
  Epicalias. 
  

  

  The 
  next 
  group 
  of 
  insects 
  I 
  shall 
  mention 
  are 
  but 
  poorly 
  repre- 
  

   sented 
  in 
  the 
  Amazon 
  valley. 
  The 
  Catagrammas 
  seem 
  to 
  abound 
  

   most 
  in 
  the 
  mountains, 
  and 
  not 
  more 
  than 
  three 
  species 
  occur 
  in 
  

   the 
  district 
  under 
  consideration. 
  As 
  might 
  be 
  expected, 
  therefore, 
  

   they 
  prefer 
  dry 
  situations, 
  and 
  are 
  very 
  active 
  in 
  their 
  move- 
  

   ments 
  ; 
  they 
  often 
  settle 
  on 
  the 
  ground 
  and 
  on 
  trunks 
  of 
  trees, 
  

   and 
  after 
  rain 
  come 
  to 
  the 
  open 
  places 
  about 
  houses. 
  The 
  He- 
  

   terochroas, 
  the 
  representatives 
  of 
  the 
  Ltmenitis 
  of 
  the 
  old 
  world, 
  

   resemble 
  them 
  in 
  their 
  steady 
  sailing 
  flight. 
  They 
  are 
  found 
  in 
  

   the 
  open 
  glades 
  and 
  on 
  the 
  skirts 
  of 
  the 
  forest. 
  

  

  CalUzona 
  Jccsta 
  and 
  Gynec'ta 
  Dirce 
  are 
  two 
  singular 
  butterflies, 
  

   resembling 
  one 
  another 
  in 
  their 
  markings 
  and 
  in 
  their 
  habits. 
  

   They 
  settle 
  upon 
  trunks 
  of 
  trees 
  as 
  invariably 
  as 
  the 
  Ageronias, 
  

   but 
  always 
  carry 
  their 
  wings 
  in 
  an 
  erect 
  position. 
  The 
  two 
  are 
  

   often 
  seen 
  together, 
  and 
  are 
  both 
  equally 
  common. 
  They 
  fre- 
  

   quent 
  trees 
  from 
  which 
  sap 
  is 
  exuding, 
  and 
  never 
  by 
  any 
  chance 
  

   rest 
  upon 
  a 
  leaf 
  or 
  flower. 
  

  

  Prepona 
  Demophron 
  and 
  Hypna 
  Chjtemnestra 
  have 
  very 
  similar 
  

   habits 
  to 
  the 
  last, 
  but 
  are 
  not 
  so 
  exclusively 
  attached 
  to 
  a 
  parti- 
  

   cular 
  station 
  ; 
  sitting 
  upon 
  a 
  stick 
  or 
  leaf 
  when 
  it 
  appears 
  most 
  

   convenient. 
  They 
  fly 
  very 
  strongly 
  and 
  delight 
  in 
  dry 
  sunny 
  

   places. 
  The 
  genera 
  Paphia 
  and 
  Sidcrone 
  have 
  very 
  similar 
  habits, 
  

   and 
  frequent 
  the 
  same 
  situations. 
  

  

  Aganisthos 
  Orion, 
  Megistanis 
  Cadmus 
  and 
  M. 
  Bccotus 
  are 
  very 
  

   strong-winged 
  insects, 
  and 
  are 
  generally 
  found 
  near 
  the 
  rivers, 
  

   preferring 
  to 
  settle 
  on 
  damp 
  spots 
  on 
  the 
  ground, 
  and 
  often 
  at 
  

   the 
  water's 
  edge, 
  where 
  in 
  the 
  dry 
  season, 
  on 
  the 
  Upper 
  Amazon 
  

   and 
  Rio 
  Negro, 
  they 
  are 
  very 
  abundant. 
  The 
  71/. 
  Bceotus 
  first 
  

   occurs 
  on 
  the 
  Amazon 
  and 
  Rio 
  Negro, 
  a 
  few 
  hundred 
  miles 
  above 
  

   their 
  junction, 
  and 
  continues 
  abundant 
  up 
  to 
  the 
  Andes. 
  The 
  blue 
  

   and 
  the 
  orange 
  varieties 
  are 
  found 
  together, 
  and 
  in 
  almost 
  equal 
  

   numbers, 
  and 
  there 
  is 
  little 
  doubt 
  are 
  sexes 
  of 
  one 
  species.
