  The 
  body 
  is 
  brownish 
  ochraeeous, 
  heavily 
  banded 
  with 
  blackish 
  

   brown, 
  the 
  proportions 
  of 
  the 
  two 
  varying 
  somewhat. 
  The 
  head 
  

   (excepting 
  the 
  vertex 
  and 
  a 
  broad 
  stripe 
  behind 
  the 
  eyes 
  which 
  are 
  

   blackish 
  brown) 
  and 
  the 
  fore 
  and

  legs 
  are 
  dirty 
  ochraeeous, 
  

   darker

  an 
  olivaceous 
  tinge, 
  and 
  the 
  

   same 
  color 
  is 
  found 
  on 
  the 
  whole 
  under

  of 
  the 
  body 
  and 
  the 
  lower 
  

   half 
  or 
  less 
  of 
  the 
  lateral 
  lobes 
  of 
  the 
  pronotum; 
  the 
  broad 
  dark 
  band 
  

   behind 
  the 
  eyes 
  continues 
  across 
  the 
  upper 
  half 
  of 
  the 
  lateral 
  lobes 
  

   and 
  the 
  whole 
  of 
  the 
  abdomen, 
  bordered 
  above 
  by 
  an 
  ochraeeous 
  stripe, 
  

   which 
  begins 
  between 
  the 
  eyes, 
  bordering 
  their 
  upper 
  margin, 
  and 
  con- 
  

   tinues 
  to 
  the 
  end 
  of 
  the 
  abdomen, 
  often 
  becoming 
  duller 
  in 
  color 
  as 
  it 
  

   approaches 
  the 
  extremity 
  and 
  is 
  more 
  narrowly 
  separated 
  from 
  its 
  

   mate; 
  sometimes 
  the 
  intervening 
  dark 
  strii)e, 
  which 
  occui^ies 
  most 
  of 
  

   the 
  vertex 
  of 
  the 
  head, 
  and 
  is 
  always 
  broader 
  anteriorly 
  than 
  posteri- 
  

   orly, 
  is 
  interrupted 
  at 
  the 
  metazona 
  and 
  on 
  the 
  meso- 
  and 
  metanota, 
  so 
  

   that 
  the 
  lighter 
  bands 
  here 
  unite.
