  The 
  form 
  which 
  occurs 
  here, 
  how- 
  

   ever, 
  differs 
  from 
  the 
  typical 
  vitifex 
  by 
  having 
  a 
  large 
  black 
  spot 
  on 
  

   either 
  side 
  of 
  the 
  scutellum 
  at 
  the 
  base, 
  by 
  having 
  the 
  red 
  line 
  on 
  the 
  

   middle 
  of 
  the 
  thorax 
  usually 
  not 
  forked 
  in 
  front, 
  and 
  by 
  not 
  having 
  the 
  

  

  i-ed 
  on 
  the 
  head 
  in 
  two 
  lines, 
  but 
  in 
  a 
  

   large 
  blotch 
  more 
  or 
  less 
  spotted 
  with 
  

   whitish. 
  

  

  The 
  illustration 
  (Fig. 
  IL'7) 
  was 
  made 
  

   from 
  a 
  specinien 
  that 
  most 
  nearly 
  ap 
  

   proac'hes 
  a 
  typical 
  HUfex 
  in 
  coloration. 
  

   It 
  seems 
  that 
  the 
  Colorado 
  Ibrm 
  is 
  a 
  

   very 
  distinctly 
  marked 
  variety, 
  and 
  

   for 
  it 
  I 
  suggest 
  the 
  name 
  Coloraden.sis. 
  

   The 
  two 
  spots 
  on 
  the 
  scutellum, 
  which 
  

   are 
  perfectly 
  constant, 
  will 
  alone 
  se]>a- 
  

   rate 
  it 
  from 
  the 
  eastern 
  form.
