  It 
  has 
  also 
  been 
  reported 
  from 
  the 
  Yellowstone 
  region 
  and

  (Bruner),

  (Scudder), 
  

   and

  Valley,

  (Coquillett). 
  

  

  I 
  have 
  found 
  this 
  insect 
  only 
  upon 
  the 
  sage 
  brush 
  (Artemisia), 
  and 
  so 
  

   completely 
  do 
  its 
  gray 
  and 
  rusty 
  colors 
  harmonize 
  with 
  its 
  surround- 
  

   ings 
  that 
  it 
  is 
  extremely 
  difficult 
  to 
  detect 
  when 
  at 
  rest. 
  This 
  has 
  

   also 
  been 
  noticed 
  by 
  Bruner, 
  who 
  remarks 
  that 
  the 
  resemblance 
  extends 
  

   to 
  the 
  earlier 
  stages 
  of 
  the 
  insect. 
  

  

  Coquillett 
  remarks 
  upon 
  the 
  ease 
  of 
  its 
  flight, 
  describing 
  it 
  as 
  in 
  a 
  

   straight 
  line, 
  for 
  a 
  distance 
  of 
  from 
  5 
  to 
  20 
  feet 
  from 
  the 
  ground. 
  He 
  

   found 
  it 
  devouring 
  the 
  ripe 
  kernels 
  of 
  rye 
  in 
  California, 
  and 
  Riley 
  

   reports 
  it 
  as 
  injuring 
  cotton 
  in 
  Louisiana. 
  Coquillett 
  regards 
  it 
  as 
  a 
  

   migrating 
  species, 
  but 
  his 
  specitic 
  statements 
  refer 
  only 
  to 
  short 
  flights 
  

   from 
  the 
  rtelds 
  to 
  the 
  tree 
  tops 
  or 
  the 
  reverse, 
  fifty 
  to 
  one 
  hundred 
  

   yards 
  being 
  the 
  usual 
  distance. 
  In 
  the 
  San 
  Joaquin 
  Valley 
  he 
  found 
  

   specimens 
  pairing 
  at 
  the 
  last 
  of 
  July.

  Nearly 
  uniform 
  light 
  testaceous. 
  Head 
  slightly 
  prominent 
  in 
  the 
  

   male, 
  hardly 
  darker 
  above 
  than 
  elsewhere, 
  with 
  no 
  trace 
  or 
  but 
  feeblest 
  

   trace 
  of 
  any 
  postocular 
  band; 
  vertex 
  very 
  gently 
  tumid, 
  hardly 
  elevated
