  north, 
  and 
  Los 
  Angeles 
  County, 
  in 
  the 
  south. 
  The 
  typical 
  forms 
  are 
  

   very 
  dark, 
  having- 
  tegmiua 
  surpassing 
  but 
  little 
  the 
  hind 
  femora, 
  with 
  

   meager 
  maculation 
  of 
  the 
  discoidal 
  area, 
  rarely 
  at 
  all 
  cinereous 
  in 
  the 
  

   basal 
  half; 
  the 
  hind 
  tibiae 
  are 
  variable 
  in 
  color. 
  

  

  A 
  second 
  form, 
  which 
  appears 
  to 
  be 
  the 
  widest 
  spread, 
  occurring 
  in 
  

   nearly 
  every 
  county 
  in 
  which 
  the 
  species 
  has 
  been 
  found, 
  from 
  Shasta 
  

   to 
  San 
  Diego 
  and 
  from 
  Marin 
  to 
  Sierra, 
  is 
  of 
  a 
  decidedly 
  cinereous 
  

   aspect, 
  with 
  abundant 
  and 
  generally 
  rather 
  confused 
  maculation 
  in 
  the 
  

   discoidal 
  area 
  of 
  the 
  tegmiua, 
  which 
  usually 
  much 
  surpass 
  the 
  hind 
  

   femora; 
  the 
  hind 
  tibiae 
  are 
  variable, 
  but 
  rarely 
  glaucous. 
  This 
  form 
  

   best 
  represents 
  the 
  original 
  types 
  of 
  the 
  species 
  when 
  first 
  described, 
  

   and 
  being 
  also 
  the 
  most 
  common 
  may 
  bear 
  the 
  name 
  Jl. 
  d. 
  typicaJis 
  

   (Plate 
  XIII, 
  fig. 
  5). 
  It 
  is 
  of 
  medium 
  size. 
  

  

  The 
  third 
  form 
  is 
  also 
  of 
  medium 
  size 
  and 
  is 
  very 
  closely 
  related 
  to 
  

   the 
  last, 
  and 
  often 
  hardly 
  distinguishable. 
  It 
  may 
  be 
  called 
  21. 
  d. 
  

   atfinis^ 
  (Plate 
  XIII, 
  fig. 
  6). 
  It 
  differs 
  principally 
  by 
  its 
  shorter 
  teg- 
  

   mina, 
  which 
  rarely 
  surpass 
  the 
  hind 
  femora, 
  and 
  which 
  are 
  very 
  sharply 
  

   maculate, 
  with 
  well-defined 
  spots, 
  and 
  the 
  hind 
  tibiae 
  are 
  usually 
  glau- 
  

   cous, 
  occasionally 
  luteous. 
  I 
  have 
  seen 
  specimens 
  from 
  Sierra, 
  Sacra- 
  

   mento, 
  and 
  Los 
  Angeles 
  counties. 
  

  

  The 
  fourth 
  form 
  is 
  by 
  far 
  the 
  largest 
  and 
  the 
  most 
  heavily 
  marked 
  of 
  

   all, 
  besides 
  being 
  of 
  a 
  rather 
  light 
  tint, 
  in 
  which 
  the 
  dark 
  maculations 
  

   appear 
  with 
  the 
  greater 
  distinctness, 
  and 
  it 
  may 
  accordingly 
  be 
  known 
  

   as 
  .1/. 
  (7. 
  conspicuus 
  (Plate 
  XIII, 
  fig. 
  7). 
  It 
  appears 
  much 
  like 
  an 
  exag- 
  

   gerated 
  form 
  of 
  the 
  last-mentioned 
  type, 
  and 
  has 
  a 
  more 
  prominent 
  

   head, 
  much 
  longer 
  tegmiua, 
  which 
  well 
  surpass 
  the 
  hind 
  femora, 
  and 
  

   ample 
  wings, 
  so 
  that 
  I 
  suspect 
  the 
  migrating 
  flights 
  will 
  be 
  found 
  to 
  be 
  

   composed 
  mainly 
  or 
  exclusively 
  of 
  this 
  form 
  ; 
  the 
  pronotum 
  is 
  unusually 
  

   clear 
  of 
  lateral 
  markings, 
  and 
  the 
  hind 
  tibiae 
  are 
  pale 
  glaucous. 
  It 
  has 
  

   not 
  been 
  found 
  south 
  of 
  the 
  center 
  of 
  the 
  State 
  (nor 
  have 
  any 
  migratory 
  

   hordes 
  been 
  reported 
  there), 
  and 
  indeed 
  only 
  in 
  the 
  central 
  portions 
  

   and 
  the 
  elevated 
  districts, 
  namely, 
  in 
  Sacramento, 
  Eldorado, 
  Amador, 
  

   and 
  Merced 
  counties.
