  Art. 
  XVII. 
  — 
  On 
  a 
  Hymenopterous 
  Insect 
  parasitic 
  on 
  Coccidse. 
  

  

  By 
  W. 
  M. 
  Maskell, 
  

  

  [Read 
  before 
  the 
  Philosophical 
  Institute 
  of 
  Canterbury, 
  4:th 
  July, 
  1878.] 
  

  

  Plate 
  IX, 
  

  

  Some 
  of 
  the 
  Coccids 
  are 
  much 
  trouhled 
  by 
  parasites. 
  In 
  this 
  country 
  I 
  

   have 
  not 
  found 
  this 
  to 
  be 
  the 
  case 
  upon 
  the 
  naked-bodied 
  species, 
  Lecanium, 
  

   etc. 
  But 
  some 
  of 
  the 
  Diaspidte, 
  particularly 
  MytUaspis 
  pomorum, 
  have 
  often 
  

   in 
  their 
  shells 
  minute 
  white 
  Acari 
  ; 
  and 
  as 
  in 
  these 
  cases 
  many 
  of 
  the 
  

   enclosed 
  eggs 
  have 
  been 
  shrivelled 
  or 
  empty, 
  I 
  imagine 
  that 
  the 
  Acarus 
  may 
  

   devour 
  them. 
  

  

  The 
  insect 
  I 
  am 
  now 
  describing 
  attacks 
  some 
  of 
  the 
  indigenous 
  test- 
  

   bearing 
  Coccidte. 
  When 
  in 
  June, 
  1877, 
  I 
  found 
  my 
  first 
  specimens 
  of 
  

   Ctenochiton 
  perforatus, 
  I 
  did 
  not 
  at 
  first 
  understand 
  the 
  nature 
  of 
  an 
  object
