  duced 
  into 
  Hawaii 
  in 
  1922 
  where, 
  according 
  to 
  Pemberton, 
  it 
  proved 
  so 
  

   efficient 
  as 
  practically 
  to 
  exterminate 
  its 
  host. 
  More 
  recently 
  it 
  was 
  

   introduced 
  into 
  Puerto 
  Rico 
  where, 
  according 
  to 
  the 
  above-cited 
  report 
  

   of 
  the 
  Puerto 
  Eican 
  Experiment 
  Station, 
  it 
  gives 
  every 
  indication 
  of 
  

   bringing 
  the 
  host 
  insect 
  under 
  complete 
  control.

  Known 
  only 
  from 
  the 
  type, 
  a 
  single 
  female, 
  said 
  to 
  have 
  been 
  reared 
  

   from 
  the 
  stems 
  of 
  Elyrrms 
  virginicus, 
  at 
  Villa 
  Ridge, 
  111. 
  The 
  real 
  

   host 
  was 
  probably 
  a 
  pseudococcine 
  scale 
  on 
  the 
  Elymus, 
  as 
  Timber- 
  

   lake 
  pointed 
  out.

   No

  the

  P. 
  angelicns 
  was 
  originally 
  described 
  from 
  Los 
  Angeles, 
  Calif., 
  as 
  

   a 
  parasite 
  of 
  Pseudococcus 
  sp. 
  on 
  passionflower. 
  It 
  has 
  since 
  been 
  

   recorded 
  by 
  Timberlake 
  as 
  parasitizing 
  Pseiuiococcus 
  {longispinus 
  

   Tsirgiom) 
  = 
  adonidum 
  (Linnaeus), 
  ryani 
  (Coquillett), 
  and 
  {citro- 
  

   philus 
  Clausen) 
  = 
  gahani 
  Green; 
  by 
  Clausen 
  from 
  Pseudococcits 
  

   maritiinus 
  (Ehrhorn) 
  and 
  gahani 
  Green; 
  and 
  by 
  Flanders 
  from 
  

   Pseudococcus 
  adonidu/m 
  (Linnaeus) 
  and 
  Phenacoccus 
  gossypii 
  Town- 
  

   send 
  and 
  Cockerell. 
  All 
  these 
  records 
  are 
  of 
  occurrences 
  of 
  the 
  species 
  

   in 
  California, 
  and 
  thus 
  far 
  it 
  is 
  not 
  known 
  to 
  occur 
  outside 
  of 
  that 
  

   State. 
  

  

  Timberlake 
  has 
  given 
  a 
  satisfactory 
  description 
  of 
  this 
  species 
  in 
  

   the 
  paper 
  cited 
  above, 
  except 
  that 
  it 
  should 
  be 
  not^d 
  that 
  the 
  trans- 
  

   verse 
  fuscous 
  band 
  on 
  the 
  cheeks 
  which 
  he 
  mentions 
  is 
  not 
  always 
  

   present. 
  

  

  8. 
  PSEUDAPHYCUS 
  ABSTRUSUS, 
  new 
  species 
  

  

  The 
  specimens 
  to 
  which 
  this 
  name 
  is 
  here 
  assigned 
  have 
  proved 
  

   exceedingly 
  puzzling 
  (hence 
  the 
  specific 
  name). 
  

  

  Female. 
  — 
  Length 
  0.94 
  mm. 
  Apparently 
  agreeing 
  in 
  every 
  respect 
  

   with 
  females 
  of 
  angelicus 
  except 
  that 
  the 
  frontovertex 
  is 
  very 
  slightly 
  

   narrower 
  than 
  in 
  that 
  species, 
  and 
  the 
  general 
  color 
  is 
  somewhat
