  Scale 
  of 
  adult 
  $ 
  about 
  2 
  mm. 
  long, 
  moderately 
  broadened 
  behind, 
  convex, 
  usually 
  

   curved, 
  white, 
  not 
  glossy, 
  but 
  with 
  ± 
  conspicuous 
  growth-lines 
  ; 
  exuviae 
  orange- 
  

   brown 
  to 
  dark 
  brown. 
  The 
  colour 
  of 
  the 
  second 
  exuviae 
  is 
  only 
  slightly 
  obscured 
  by 
  

   a 
  faint 
  secretionary 
  covering. 
  

  

  Puparium 
  of 
  <J 
  comparatively 
  large, 
  white, 
  non-carinate, 
  with 
  yellow 
  or 
  orange 
  

   exuviae. 
  

  

  Adult 
  O, 
  when 
  mounted, 
  regular 
  in 
  outline, 
  about 
  1*3 
  mm. 
  long, 
  elongate, 
  widest 
  

   behind 
  the 
  middle, 
  hyaline, 
  except 
  the 
  median 
  lobes 
  which 
  are 
  very 
  deuse, 
  and 
  the 
  

   middle 
  part 
  of 
  the 
  pygidium 
  which 
  is 
  yellowish. 
  The 
  segmentation 
  of 
  the 
  body 
  is 
  

   unusually 
  distinct 
  but 
  is 
  not 
  strongly 
  marked 
  at 
  the 
  margins, 
  nor 
  are 
  the 
  abdominal 
  

   segments 
  produced. 
  

  

  The 
  pygidial 
  margin 
  is 
  simple. 
  There 
  is 
  only 
  one 
  pair 
  of 
  lobes 
  present, 
  which 
  are 
  

   short 
  and 
  broad, 
  densely 
  chitinised, 
  brown, 
  with 
  the 
  rounded 
  outer 
  margin 
  once 
  

   notched. 
  Plates 
  are 
  apparently 
  absent, 
  but 
  there 
  are 
  two 
  stout 
  spines 
  on 
  each 
  side.
