  tivorous 
  birds. 
  Most 
  of 
  the 
  other 
  strange 
  developments 
  seem 
  to 
  be 
  protected 
  

   by 
  simulating 
  some 
  part 
  of 
  the 
  plant 
  on 
  which 
  they 
  live 
  or 
  else 
  so 
  arranged 
  as 
  to 
  

   blend 
  into 
  the 
  lights 
  and 
  shadows 
  of 
  their 
  favorite 
  situation 
  as 
  to 
  render 
  them 
  

   inconspicuous. 
  For 
  example, 
  a 
  species 
  that 
  lives 
  on 
  the 
  oak 
  has 
  a 
  white 
  

   stripe 
  down 
  the 
  middle 
  of 
  the 
  back 
  which 
  is 
  very 
  striking 
  when 
  seen 
  in 
  a 
  

   collection. 
  This 
  insect, 
  however, 
  in 
  life 
  rests 
  on 
  the 
  underside 
  of 
  a 
  twig 
  in 
  

   the 
  shadows 
  and 
  this 
  white 
  stripe 
  then 
  functions 
  like 
  the 
  light 
  under 
  part 
  of 
  

   the 
  deer 
  or 
  of 
  many 
  birds 
  and 
  helps 
  it 
  to 
  blend 
  with 
  its 
  surroundings. 
  

  

  The 
  adaptation 
  of 
  these 
  insects 
  to 
  their 
  surroundings 
  in 
  color 
  and 
  mark- 
  

   ings 
  is 
  if 
  anything 
  even 
  more 
  striking 
  than 
  their 
  grotesque 
  shapes. 
  A 
  study 
  

   -of 
  the 
  North 
  American 
  species 
  of 
  Telamonini 
  shows 
  that 
  nearly 
  every 
  one 
  

   of 
  them 
  has 
  a 
  single 
  food 
  plant 
  to 
  which 
  it 
  is 
  almost 
  perfectly 
  adapted 
  in 
  color 
  

   and 
  form, 
  these 
  adaptations 
  being 
  combined 
  to 
  produce 
  invisibility 
  in 
  the 
  

   favorite 
  situation 
  of 
  the 
  individual 
  treehopper. 
  The 
  one 
  occurring 
  on 
  wild 
  

   plum, 
  for 
  example, 
  has 
  the 
  color 
  of 
  the 
  plum 
  bark 
  and 
  a 
  long 
  projection 
  like 
  

   a 
  plum 
  thorn. 
  The 
  one 
  on 
  sycamore 
  has 
  the 
  powdery 
  yellow 
  appearance 
  of 
  

   the 
  fresh 
  bark 
  of 
  that 
  tree. 
  The 
  one 
  on 
  hackberry 
  rests 
  in 
  crevices 
  in 
  the 
  

   bark 
  and 
  mimics 
  the 
  rough 
  outline 
  of 
  the 
  black 
  and 
  gray 
  flecking 
  of 
  the 
  

   rough 
  bark. 
  

  

  Collecting 
  these 
  insects 
  is 
  as 
  fascinating 
  as 
  trout 
  fishing. 
  It 
  is 
  only 
  the 
  

   trained 
  eye 
  that 
  can 
  detect 
  them 
  and 
  when 
  detected 
  it 
  is 
  only 
  by 
  the 
  use 
  of 
  

   the 
  greatest 
  skill 
  that 
  they 
  can 
  be 
  captured, 
  as 
  once 
  disturbed 
  they 
  snap 
  into 
  

   the 
  air 
  with 
  eye-defying 
  speed 
  and 
  are 
  lost 
  in 
  the 
  foliage. 
  If 
  one 
  uses 
  a 
  long 
  

   glass 
  tube 
  and 
  brings 
  it 
  down 
  from 
  directly 
  above 
  the 
  insect 
  without 
  allowing 
  

   the 
  slightest 
  lateral 
  movement 
  they 
  may 
  be 
  readily 
  captured. 
  They 
  are 
  

   lovers 
  of 
  the 
  open 
  and 
  of 
  warm 
  and 
  sunshiny 
  places 
  and 
  will 
  be 
  found 
  on 
  

   isolated 
  trees 
  or 
  small 
  clumps 
  or 
  on 
  the 
  margins 
  of 
  woods 
  but 
  not 
  inside 
  the 
  

   wooded 
  area 
  or 
  in 
  the 
  deep 
  shade. 
  Fortunately 
  for 
  the 
  collector 
  most 
  of 
  

   them 
  occur 
  on 
  the 
  low 
  spreading 
  branches 
  of 
  the 
  large 
  trees. 
  

  

  Notes 
  and 
  exhibition 
  of 
  specimens 
  

  

  Mr. 
  B. 
  A. 
  Porter 
  reported 
  the 
  rearing 
  at 
  Wallingford, 
  Connecticut, 
  of 
  

   Anaphoidea 
  conotracheli 
  Girault, 
  a 
  common 
  parasite 
  of 
  the 
  plum 
  curculio, 
  from 
  

   the 
  eggs 
  of 
  the 
  apple 
  maggot. 
  As 
  high 
  as 
  25 
  and 
  30 
  per 
  cent 
  of 
  the 
  apple 
  

   maggot 
  eggs 
  collected 
  in 
  the 
  field 
  have 
  been 
  found 
  to 
  be 
  parasitized 
  by 
  this 
  

   insect. 
  The 
  egg 
  turns 
  dark 
  just 
  before 
  the 
  emergence 
  of 
  the 
  parasite, 
  which 
  

   instead 
  of 
  using 
  the 
  oviposition 
  puncture 
  made 
  in 
  the 
  fruit 
  by 
  the 
  fly 
  makes 
  

   a 
  hole 
  of 
  its 
  own 
  through 
  the 
  skin 
  of 
  the 
  apple. 
  The 
  life 
  cycle 
  of 
  the 
  parasite 
  

   was 
  not 
  definitely 
  determined 
  but 
  data 
  available 
  show 
  it 
  to 
  be 
  less 
  than 
  three 
  

   weeks. 
  In 
  the 
  plum 
  curculio 
  it 
  is 
  10-11 
  daj^s. 
  The 
  oviposition 
  season 
  of 
  

   the 
  apple 
  maggot 
  following 
  that 
  of 
  the 
  plum 
  curculio 
  gives 
  a 
  favorable 
  host 
  

   rotation 
  from 
  June 
  to 
  September. 
  The 
  only 
  other 
  recorded 
  host 
  of 
  this 
  para- 
  

   site 
  is 
  the 
  grape 
  curculio. 
  

  

  Dr. 
  Howard 
  was 
  much 
  interested 
  in 
  the 
  observation 
  and 
  expressed 
  the 
  

   opinion 
  that 
  any 
  delicate 
  egg 
  deposited 
  in 
  the 
  same 
  position 
  as 
  those 
  of 
  the 
  

   curculio 
  and 
  the 
  maggot 
  would 
  serve 
  as 
  host 
  for 
  the 
  Anaphoidea. 
  

  

  Mr. 
  Gahan 
  mentioned 
  Trichogramma 
  mimita 
  Riley 
  as 
  another 
  example 
  of 
  

   a 
  parasite 
  attacking 
  eggs 
  of 
  insects 
  of 
  different 
  orders. 
  

  

  Dr. 
  J. 
  M. 
  Aldrich, 
  editor 
  of 
  the 
  Thomas 
  Say 
  Foundation, 
  stated 
  that 
  the 
  

   Foundation 
  would 
  shortly 
  be 
  able 
  to 
  publish 
  another 
  memoir 
  and 
  asked 
  for 
  

   the 
  opportunity 
  to 
  examine 
  any 
  manuscripts 
  that 
  might 
  be 
  available.
