  This

  agree 
  in 
  the

  of

  the 
  body 
  

   densely 
  cinereous

  red, 
  

   the

  it 
  must 
  be, 
  I 
  should 
  

   think,

  although 
  the 
  apex 
  of 
  the 
  median

   ment

  truncated, 
  yet 
  it

  obtuse

  and 
  the 
  third 
  cubital 
  

   cellule 
  is 
  called 
  " 
  subtriangular,"

  here 
  it

  distinctly 
  

   petiolated
