  however, 
  may 
  be 
  found 
  almost 
  everywhere, 
  hovering 
  slowly 
  along 
  

   in 
  shady 
  woods 
  and 
  plantations, 
  and 
  offering 
  an 
  easy 
  prey 
  to 
  the 
  

   Entomologist, 
  as 
  well 
  as 
  to 
  the 
  more 
  merciless 
  insect-eating 
  birds. 
  

   The 
  species 
  of 
  Terias 
  prefer 
  rather 
  the 
  dry 
  and 
  more 
  open 
  parts 
  

   of 
  the 
  forest 
  country, 
  and 
  often 
  even 
  come 
  out 
  into 
  the 
  full 
  sun- 
  

   shine. 
  Several 
  species 
  of 
  Pleris 
  accompany 
  them 
  ; 
  but 
  they 
  

   cannot 
  vie 
  in 
  strength 
  and 
  rapidity 
  of 
  flight 
  with 
  the 
  species 
  of 
  

   CaUiilryas, 
  which 
  rejoice 
  in 
  the 
  hottest 
  sunshine, 
  and 
  crowd 
  in 
  

   dense 
  masses 
  of 
  several 
  yards 
  in 
  extent 
  around 
  puddles 
  and 
  on 
  

   sandy 
  beaches, 
  rising 
  in 
  clouds 
  of 
  yellow 
  and 
  orange 
  on 
  being 
  

   disturbed. 
  

  

  The 
  Rhodoceras 
  again 
  are 
  of 
  a 
  sylvan 
  taste, 
  the 
  handsome 
  R. 
  

   Leach'iana 
  being 
  found 
  only 
  in 
  open 
  paths 
  through 
  the 
  forest. 
  

  

  We 
  now 
  come 
  to 
  a 
  group 
  of 
  insects 
  peculiar 
  to 
  America, 
  the 
  

   Ageronidce, 
  and 
  in 
  them 
  we 
  first 
  see 
  a 
  deviation 
  from 
  the 
  normal 
  

   manner 
  of 
  carrying 
  the 
  wings 
  in 
  repose; 
  the 
  species 
  of 
  this 
  family 
  

   invariably 
  resting 
  with 
  the 
  wings 
  expanded. 
  Five 
  species 
  are 
  

   found 
  about 
  Para, 
  and 
  they 
  all 
  frequent 
  dry 
  situations, 
  and 
  always 
  

   settle 
  on 
  trunks 
  of 
  trees, 
  with 
  the 
  head 
  downwards. 
  The 
  singular 
  

   noise 
  produced 
  by 
  these 
  insects 
  has 
  been 
  noticed 
  by 
  Lacordaire 
  

   and 
  Mr. 
  Darwin. 
  The 
  common 
  species, 
  A. 
  Feronia, 
  produces 
  it 
  

   remarkably 
  loud, 
  when 
  two 
  insects 
  are 
  chasing 
  each 
  other 
  and 
  

   constantly 
  striking 
  together. 
  One 
  alone 
  does 
  not 
  produce 
  the 
  

   sound 
  in 
  flying 
  ; 
  and 
  I 
  have 
  never 
  heard 
  it 
  made 
  by 
  the 
  small 
  

   species, 
  A. 
  Chloe, 
  which 
  is 
  equally 
  common 
  with 
  the 
  other. 
  I 
  am 
  

   inclined, 
  therefore, 
  to 
  believe 
  that 
  it 
  is 
  produced 
  in 
  some 
  way 
  by 
  

   the 
  contact 
  of 
  two 
  insects, 
  and 
  that 
  only 
  the 
  larger 
  and 
  stronger 
  

   winged 
  species 
  can 
  produce 
  it. 
  

  

  Like 
  M. 
  Lacordaire, 
  I 
  have 
  found 
  the 
  pupa 
  of 
  a 
  species 
  of 
  this 
  

   family, 
  but 
  never 
  the 
  larva. 
  It 
  agreed 
  exactly 
  with 
  his 
  descrip- 
  

   tion, 
  and 
  was 
  attached 
  to 
  a 
  post, 
  and 
  braced 
  like 
  that 
  of 
  a 
  Papilio. 
  

  

  Of 
  the 
  Danaidce 
  two 
  species 
  only 
  are 
  found 
  on 
  the 
  Amazon. 
  

   They 
  frequent 
  the 
  most 
  open 
  situations, 
  fly 
  low, 
  and 
  constantly 
  

   settle 
  on 
  herbaceous 
  plants. 
  In 
  the 
  beautiful 
  family 
  of 
  lieliconidce, 
  

   the 
  glory 
  of 
  South 
  American 
  Entomology, 
  the 
  Amazon 
  valley 
  is 
  

   particularly 
  rich, 
  at 
  least 
  sixty 
  or 
  seventy 
  species 
  being 
  found 
  

   there, 
  of 
  which 
  a 
  considerable 
  number 
  seem 
  peculiar. 
  And 
  here 
  

   the 
  same 
  thing 
  takes 
  place 
  which 
  we 
  observed 
  with 
  regard 
  to 
  the 
  

   Pap'dios, 
  — 
  that 
  the 
  more 
  rare 
  and 
  restricted 
  species 
  are 
  those 
  which 
  

   inhabit 
  the 
  forest, 
  while 
  the 
  species 
  found 
  in 
  the 
  open 
  grounds 
  

   are 
  generally 
  widely 
  distributed, 
  and 
  often 
  seem 
  mere 
  stragglers 
  

   from 
  other 
  parts 
  of 
  the 
  continent. 
  Among 
  these 
  latter 
  are 
  Lijcorea 
  

   Halia, 
  Tithorca 
  Mcgara, 
  and 
  Mcchanitis 
  Lrjsidice,
