  In 
  order 
  to 
  establish 
  the 
  taxonomic 
  status 
  of 
  the 
  weevil 
  breeding 
  in 
  

   Arizona 
  wild 
  cotton 
  (Thurberia 
  thespesioides) 
  the 
  authors 
  undertook 
  

   a 
  number 
  of 
  studies, 
  the 
  results 
  of 
  which 
  are 
  given 
  in 
  the 
  present 
  

   paper. 
  This 
  weevil 
  very 
  closely 
  resembles 
  the 
  Mexican 
  cotton 
  boll 
  

   weevil 
  (Anthonomus 
  grandis), 
  and 
  an 
  account 
  of 
  it 
  has 
  already 
  been 
  

   given, 
  under 
  the 
  name 
  of 
  A. 
  grandis 
  var. 
  thurberiae 
  [see 
  this 
  Review, 
  

   Ser. 
  A, 
  ii, 
  pp. 
  78-79]. 
  Experiments 
  were 
  made, 
  the 
  principal 
  results 
  

   of 
  which 
  were 
  to 
  show 
  that 
  the 
  two 
  varieties 
  are 
  able 
  to 
  interbreed 
  and 
  

   produce 
  fertile 
  offspring. 
  The 
  question 
  whether 
  the 
  thurberiae 
  form 
  

   will 
  flourish 
  on 
  cultivated 
  cotton 
  is 
  now 
  being 
  tested.

  The 
  Arizona 
  Wild 
  Cotton 
  plant 
  assumed 
  economic 
  importance 
  on 
  

   being 
  found 
  in 
  1913 
  to 
  harbour 
  a 
  variety 
  of 
  the 
  dreaded 
  Mexican 
  

   cotton 
  boll 
  weevil 
  (Anthonomus 
  grandis, 
  var. 
  thurberiae 
  Pierce). 
  The 
  

   authors 
  have 
  since 
  made 
  a 
  thorough 
  examination 
  of 
  the 
  insects 
  asso- 
  

   ciated 
  with 
  this 
  plant. 
  

  

  The 
  plant 
  is 
  a 
  perennial, 
  resembling 
  the 
  cotton 
  plant 
  so 
  closely 
  that 
  

   it 
  is 
  locally 
  known 
  as 
  wild 
  cotton 
  ; 
  it 
  occurs 
  at 
  altitudes 
  of 
  2,300-5,000 
  

   feet 
  in 
  Arizona. 
  The 
  species 
  of 
  insects 
  recorded 
  from 
  the 
  plant 
  are 
  

   83 
  in 
  number 
  distributed 
  as 
  follows 
  : 
  Acarina 
  1, 
  Rhynchota 
  14, 
  

   Orthoptera 
  3, 
  Thysanoptera 
  2, 
  Lepidoptera 
  7, 
  Coleoptera 
  24, 
  Hymeno- 
  

   ptera 
  29, 
  Diptera 
  2, 
  and 
  Strepsiptera 
  1 
  ; 
  according 
  to 
  their 
  behaviour 
  

   towards 
  the 
  plant 
  these 
  insects 
  may 
  be 
  classified 
  as 
  injurious 
  25, 
  

   nectar-visiting 
  40, 
  parasitic 
  12, 
  and 
  predaceous 
  6. 
  The 
  most 
  impor- 
  

   tant 
  injurious 
  insects 
  are 
  the 
  boll-weevil 
  (Anthonomus 
  grandis 
  thur- 
  

   beriae), 
  the 
  cotton 
  worm 
  (Alabama 
  argillacea), 
  the 
  Thurberia 
  boll 
  worm 
  

   (Sacadodes 
  pyralis, 
  Dyar), 
  a 
  blister 
  mite 
  (Eriophyes 
  sp.), 
  a 
  gall-forming 
  

   insect 
  belonging 
  to 
  the 
  family 
  Cecidomyiidae, 
  and 
  a 
  mealy 
  bug 
  

   {Pseudococcus 
  sp. 
  ) 
  .
