  3. 
  Lecanium 
  Mbernaculorum, 
  Targioiii. 
  

  

  Also 
  European; 
  the 
  body, 
  in 
  its 
  later 
  stages 
  becomes 
  quite 
  rounded 
  or 
  

   bag- 
  shaped, 
  the 
  open 
  mouth 
  of 
  the 
  bag 
  downwards 
  on 
  the 
  leaf. 
  The 
  bag 
  

   becomes 
  filled 
  with 
  eggs 
  and 
  young. 
  The 
  skin 
  is 
  marked 
  with 
  small 
  spots 
  

   at 
  pretty 
  regular 
  distances. 
  It 
  is 
  common 
  in 
  our 
  greenhouses. 
  

  

  4. 
  Lecanium 
  maculatum, 
  Signoret. 
  

  

  European 
  ; 
  occurring 
  here 
  on 
  a 
  hothouse 
  plant, 
  Bavarclia. 
  The 
  species 
  

   is 
  distinguished 
  by 
  a 
  row 
  of 
  oval 
  spots 
  commencing 
  above 
  the 
  abdominal 
  

   lobes 
  and 
  extending 
  up 
  the 
  centre 
  of 
  the 
  dorsal 
  region 
  as 
  far 
  as 
  the 
  rostrum. 
  

  

  I 
  need 
  not 
  dwell 
  longer 
  on 
  the 
  species 
  of 
  Lecaniese 
  ; 
  there 
  are 
  others 
  

   here, 
  but 
  Eur'opean. 
  Nor 
  shall 
  I 
  dwell 
  upon 
  the 
  next 
  subsection 
  on 
  my 
  list. 
  

  

  II. 
  PULVINARIEJE. 
  

  

  As 
  far 
  as 
  my 
  observation 
  has 
  extended, 
  this 
  subsection 
  is 
  confined 
  here 
  

   to 
  one 
  species, 
  namely, 
  the 
  Camellia 
  scale. 
  

  

  5. 
  Pulvinaria 
  camellicola, 
  Signoret. 
  

  

  The 
  insect, 
  which 
  is 
  European, 
  differs 
  from 
  Lecanium 
  hesperidiim 
  chiefly 
  

   in 
  its 
  mode 
  of 
  propagation. 
  Instead 
  of 
  producing 
  the 
  young 
  beneath 
  itself 
  

   it 
  forms 
  elongated 
  cocoons 
  of 
  white 
  cottony 
  fibre 
  in 
  which 
  it 
  encloses 
  its 
  

   eggs. 
  I 
  have 
  not 
  been 
  fortunate 
  enough 
  to 
  procure 
  a 
  male, 
  although, 
  as 
  I 
  

   understand, 
  it 
  is 
  not 
  rare. 
  

  

  III. 
  — 
  Lecanio-diaspid^, 
  Targioni. 
  

  

  I 
  come 
  now 
  to 
  my 
  third 
  subsection, 
  containing 
  in 
  this 
  country 
  only 
  

   genera 
  and 
  species 
  which 
  are, 
  as 
  I 
  believe, 
  new 
  to 
  science. 
  The 
  subsection 
  

   itself 
  has 
  been 
  created 
  by 
  Professor 
  Targioni-Tozzetti, 
  of 
  Florence, 
  in 
  order 
  

   to 
  include 
  those 
  genera 
  of 
  Coccidae 
  which 
  partake 
  of 
  the 
  characters 
  of 
  the 
  

   Lecanidse 
  and 
  of 
  the 
  characters 
  of 
  the 
  Diaspidse. 
  They 
  have 
  the 
  mentum 
  

   and 
  abdominal 
  lobes 
  of 
  Lecanium, 
  but 
  they 
  are 
  surrounded 
  by 
  a 
  shell, 
  shield 
  

   or 
  test, 
  as 
  in 
  Diaspis. 
  This 
  test 
  or 
  carapace 
  is 
  therefore 
  a 
  character 
  clearly 
  

   distinguishing 
  them 
  from 
  the 
  other 
  Lecanidte 
  which 
  have 
  the 
  body 
  naked 
  in 
  

   all 
  its 
  stages 
  ; 
  at 
  the 
  same 
  time 
  the 
  abdominal 
  lobes 
  forbid 
  their 
  entrance 
  

   into 
  any 
  other 
  group. 
  

  

  It 
  would 
  appear 
  that 
  Professor 
  Targioni 
  makes 
  one 
  of 
  the 
  distinguishing 
  

   characters 
  of 
  this 
  subsection 
  the 
  fact 
  that 
  the 
  insects 
  lose 
  then- 
  limbs 
  like 
  

   the 
  Diaspidse, 
  "becoming 
  apodous 
  in 
  the 
  adult 
  stage." 
  Now 
  the 
  genera 
  

   and 
  species 
  which 
  I 
  have 
  to 
  describe 
  do 
  not 
  all 
  entirely 
  agree 
  with 
  this 
  

   account. 
  The 
  feet 
  and 
  antennae 
  are 
  preserved 
  at 
  least 
  until 
  the 
  female 
  has 
  

   propagated 
  her 
  young 
  and 
  sometimes 
  still 
  later, 
  although 
  in 
  other 
  instances 
  

   I 
  have 
  been 
  unable 
  to 
  detect 
  the 
  limbs 
  in 
  the 
  later 
  stages. 
  To 
  the 
  naked 
  

   eye, 
  indeed, 
  or 
  even 
  with 
  a 
  low 
  power 
  of 
  the 
  microscope, 
  all 
  the 
  insects 
  

   appear 
  apodous 
  ; 
  but 
  a 
  higher 
  power 
  often 
  reveals 
  the 
  limbs 
  as 
  if 
  buried 
  in 
  

   the 
  fat 
  body. 
  It 
  seems 
  to 
  me 
  that 
  I 
  have 
  therefore 
  only 
  two 
  alternatives 
  :
