   Sir: 
  I 
  have 
  the 
  honor 
  to 
  transmit 
  herewith, 
  and 
  to 
  recommend 
  for 
  

   publication 
  as 
  Bulletin 
  No. 
  117 
  of 
  the 
  Bureau 
  of 
  Entomology, 
  a 
  

   manuscript 
  entitled 
  "The 
  Red 
  Spider 
  on 
  Hops 
  in 
  the 
  Sacramento 
  

   Valley 
  of 
  California, 
  " 
  by 
  William 
  B. 
  Parker, 
  an 
  entomological 
  assistant 
  

   in 
  this 
  bureau. 
  

  

  This 
  manuscript 
  deals 
  with 
  a 
  pest 
  the 
  study 
  of 
  which 
  has 
  been 
  

   hitherto 
  largely 
  neglected 
  and 
  which 
  of 
  recent 
  years 
  has 
  attracted 
  

   much 
  attention 
  from 
  an 
  economic 
  standpoint, 
  on 
  account 
  of 
  immense 
  

   losses 
  to 
  growers 
  of 
  hops 
  and 
  other 
  crops 
  in 
  the 
  Pacific 
  coast 
  region 
  

   and 
  elsewhere. 
  

  

  Mr. 
  Parker's 
  studies, 
  as 
  outlined 
  in 
  this 
  paper, 
  have 
  added 
  con- 
  

   siderably 
  to 
  the 
  knowledge 
  of 
  the 
  habits 
  of 
  this 
  pest 
  and 
  have 
  shown 
  

   methods 
  by 
  which 
  it 
  may 
  be 
  economically 
  controlled. 
  

   Respectfully,
