  JASSOIDEA. 
  

  

  Under 
  the 
  general 
  term 
  "leaf-hoppers" 
  are 
  included 
  a 
  large 
  number 
  of 
  

   active 
  little 
  species 
  referred 
  to 
  the 
  families 
  Tettigoniellidfe, 
  Bythoscopidae 
  

   and 
  Jassids3. 
  They 
  are 
  more 
  or 
  less 
  elongate, 
  usually 
  tapering 
  posteriorly, 
  

   the 
  head 
  short, 
  generally 
  blunt 
  and 
  more 
  or 
  less 
  crescent 
  shaped, 
  the 
  tip 
  

   of 
  the 
  beak 
  projecting 
  between 
  the 
  front 
  legs. 
  The 
  feelers 
  are 
  very 
  short 
  

   and 
  bristle-like, 
  the 
  hind 
  legs 
  long 
  and 
  fitted 
  for 
  leaping. 
  They 
  occur 
  on 
  

   grasses, 
  shrubs 
  and 
  trees 
  of 
  all 
  kinds 
  and 
  many 
  of 
  them 
  are 
  injurious, 
  

   sometimes 
  much 
  more 
  so 
  than 
  is 
  generally 
  appreciated.

  species 
  occurs 
  that 
  often 
  becomes 
  excessively 
  abundant 
  after 
  mid- 
  

   summer, 
  punctures 
  the 
  cells 
  of 
  the 
  leaves 
  and 
  produces 
  a 
  yellow 
  spot 
  

   which 
  afterward 
  turns 
  brown. 
  When 
  these 
  spots 
  are 
  sufficiently 
  close 
  

   together 
  the 
  entire 
  leaf 
  dries 
  up, 
  dies 
  and 
  drops 
  long 
  before 
  the 
  shoot 
  is 
  

   mature. 
  Young 
  apple 
  trees 
  frequently 
  suffer 
  from 
  an 
  allied 
  species 
  that 
  

   yellows 
  and 
  dries 
  the 
  foliage 
  soon 
  after 
  mid-summer. 
  

  

  In 
  general, 
  the 
  insects 
  winter 
  as 
  adults 
  in 
  rubbish 
  and 
  crevices 
  and 
  lay
