  A. 
  vaporarium 
  West. 
  The 
  "white 
  fly" 
  or 
  plant-house 
  "Aleyrodes." 
  A 
  

   common 
  pest 
  of 
  green-houses 
  throughout 
  the 
  State. 
  "It 
  has 
  been 
  

   found 
  on 
  over 
  sixty 
  different 
  kinds

  A. 
  waldeni 
  Britton. 
  Described 
  from 
  Connecticut, 
  but 
  will 
  probably 
  be 
  

   found 
  in 
  New 
  Jersey. 
  Occurs 
  sparingly, 
  but 
  widely 
  scattered, 
  on 
  

   leaves 
  of 
  "Juglans 
  cinerea" 
  and 
  "nigra" 
  (W. 
  E. 
  B.). 
  

   The 
  "A. 
  brassicae 
  Wlk." 
  of 
  the 
  previous 
  edition 
  is 
  probably 
  not 
  found 
  in 
  

  

  America 
  at 
  all. 
  

  

  Family 
  COCCID/E. 
  

  

  These 
  are 
  the 
  "scale 
  insects," 
  broadly 
  speaking, 
  characterized 
  by 
  a 
  

   degraded, 
  larva-like 
  form 
  in 
  the 
  female, 
  and 
  by 
  the 
  presence 
  of 
  a 
  single 
  

   pair 
  of 
  wings 
  only 
  in 
  the 
  male. 
  The 
  latter 
  is 
  further 
  peculiar 
  in 
  having 
  

   a 
  complete 
  metamorphosis, 
  a 
  long 
  anal 
  style 
  or 
  filament 
  and 
  an 
  extra 
  

   pair 
  of 
  eyes 
  replacing 
  the 
  mouth, 
  which, 
  in 
  this 
  sex, 
  is 
  not 
  used 
  at 
  all 
  

   for 
  feeding 
  purposes. 
  

  

  There 
  are 
  several 
  sub-families, 
  differing 
  much 
  in 
  habit 
  and 
  structure, 
  

   but 
  in 
  New 
  Jersey 
  we 
  need 
  refer 
  to 
  only 
  three 
  main 
  series, 
  the 
  "mealy 
  

   bugs," 
  included 
  in 
  the 
  "Dactylopinee"; 
  the 
  "soft 
  scales," 
  included 
  in 
  the 
  

   "Coccinae," 
  and 
  the 
  "armored 
  scales," 
  included 
  in 
  the 
  "Diaspinse." 
  In 
  the 
  

   "Ortheziinse" 
  we 
  have 
  no 
  out-door 
  species. 
  In 
  the 
  "Dactylopinse" 
  there 
  

   are 
  the 
  ordinary 
  "mealy 
  bugs" 
  of 
  the 
  green-house, 
  having 
  no 
  sort 
  of 
  pro- 
  

   tective 
  covering, 
  and 
  therefore 
  easily 
  reached 
  by 
  penetrating 
  contact 
  in- 
  

   secticides; 
  the 
  species 
  of 
  "Phenacoccus" 
  and 
  allies, 
  which 
  have 
  long 
  

   waxy 
  filamentous 
  secretions, 
  partly 
  or 
  wholly 
  covering 
  the 
  insects 
  at 
  cer- 
  

   tain 
  seasons; 
  and 
  the 
  species 
  of 
  "Kermes," 
  occurring 
  mostly 
  on 
  oak, 
  which 
  

   have 
  no 
  powdery 
  or 
  filamentous 
  covering. 
  The 
  species 
  of 
  "Phenacoccus" 
  

   may 
  be 
  reached 
  during 
  the 
  winter 
  by 
  diluted 
  oil 
  mixtures, 
  and 
  in 
  sum- 
  

   mer, 
  when 
  massed, 
  may 
  be 
  often 
  destroyed 
  on 
  shade 
  trees 
  by 
  solid 
  jets 
  of 
  

   water. 
  

  

  The 
  soft 
  scales 
  are 
  species 
  of 
  usually 
  considerable 
  size, 
  waxy 
  surface 
  

   texture, 
  and 
  more 
  or 
  less 
  convex 
  form. 
  The 
  "scale" 
  is 
  merely 
  the 
  thick- 
  

   ened 
  surface 
  of 
  the 
  insect 
  itself, 
  and 
  not 
  a 
  separate 
  or 
  separable 
  structure. 
  

   These 
  insects 
  are 
  not 
  easily 
  reached 
  by 
  insecticides, 
  except 
  in 
  the 
  larval 
  

   stage, 
  and 
  we 
  have 
  several 
  of 
  them 
  that 
  are 
  more 
  or 
  less 
  troublesome.
