  have 
  received 
  .specimens 
  of 
  this 
  species 
  as 
  follows 
  : 
  From 
  Professor 
  

   H. 
  E. 
  Weed, 
  marked 
  "Ag. 
  Ooll. 
  Miss., 
  Oct. 
  22,

  from 
  Illiuois 
  State 
  

   Laboratory 
  of 
  Natural 
  History, 
  marked 
  13572 
  and 
  1730S, 
  those 
  of 
  the 
  

   latter 
  number 
  taken 
  on 
  grapes; 
  from 
  the 
  private 
  collection 
  of 
  ]\lr. 
  C. 
  A. 
  

   Hart, 
  specimens 
  bearing- 
  the 
  numbers 
  462, 
  550, 
  562, 
  and 
  566, 
  all 
  taken 
  in 
  

   Illinois: 
  also 
  from 
  Mr, 
  Hart 
  a 
  number 
  of 
  specimens 
  that 
  he 
  took 
  on 
  

   grape 
  at 
  Havana, 
  Illinois; 
  from 
  Mr, 
  F, 
  F. 
  Creveco'ur, 
  a 
  number 
  of 
  spec- 
  

   imens 
  taken 
  by 
  himself 
  in 
  early 
  

   spring 
  among 
  leaves 
  in 
  the 
  

   timber 
  at 
  ( 
  )naga, 
  Kansas 
  ; 
  from 
  

   the 
  U, 
  S. 
  National 
  Museum 
  

   si»ecimens 
  labeled 
  "Mo, 
  Riley." 
  

   This 
  is 
  a 
  very 
  pretty 
  species 
  

   that 
  varies 
  to 
  a 
  considerable 
  

   extent, 
  in 
  its 
  markings. 
  The 
  

   three 
  dusky 
  fasciae 
  are 
  very 
  

   distinct 
  in 
  some 
  specimens 
  and 
  

   almost 
  wanting 
  in 
  others 
  ; 
  some 
  

   have 
  almost 
  none 
  of 
  the 
  led 
  

   coloration, 
  while 
  others 
  are 
  

   highly 
  colored 
  upon 
  the 
  elytra 
  

   with 
  sanguineous. 
  In 
  all 
  the 
  specimens 
  that 
  I 
  have 
  examined 
  the 
  tip 
  

   of 
  the 
  scutellum 
  has 
  been 
  jet 
  black.
