  A 
  very 
  heavy 
  infestation, 
  so 
  much 
  so 
  that 
  the 
  insects 
  covered 
  a 
  very 
  large 
  propor- 
  

   tion 
  of 
  the 
  branches. 
  

  

  A 
  somewhat 
  remarkable 
  species, 
  distinguishable, 
  in 
  the 
  adult 
  female, 
  by 
  the 
  curious 
  

   character 
  of 
  the 
  derm 
  and 
  the 
  relatively 
  short 
  anal 
  cleft 
  (0*7-0 
  "8 
  mm.) 
  ; 
  in 
  the 
  second 
  

   stage 
  female 
  by 
  the 
  absence 
  of 
  marginal 
  cylindrical 
  ducts 
  to 
  the 
  glands 
  ; 
  and 
  in 
  the 
  

   larva 
  by 
  the 
  unusual 
  character 
  and 
  relative 
  position 
  of 
  the 
  tarsal 
  digitules.

  Female 
  Puparium 
  (fig. 
  16). 
  — 
  -This, 
  when 
  perfect, 
  is 
  narrowed, 
  strongly 
  produced, 
  

   and 
  slightly 
  involute 
  posteriorly, 
  resembling 
  the 
  long 
  curved 
  toe 
  of 
  an 
  Oriental 
  slipper 
  

   in 
  miniature. 
  This 
  very 
  remarkable 
  appendage 
  is 
  composed 
  of 
  both 
  dorsal 
  and 
  

   ventral 
  portions 
  of 
  the 
  capsulate 
  puparium 
  ; 
  but 
  it 
  is 
  rarely 
  found 
  intact 
  in 
  examples 
  

   which 
  have 
  been 
  submitted 
  to 
  even 
  light 
  pressure, 
  as 
  it 
  is 
  very 
  brittle 
  and 
  readily 
  

   breaks 
  away.
