  There 
  were 
  a 
  large 
  number 
  of 
  this 
  form 
  in 
  the 
  lot 
  sent 
  me 
  by 
  Mr. 
  

   Creveco'ur 
  from 
  Onaga, 
  Kansas, 
  and 
  1 
  also 
  have 
  a 
  few 
  specimens 
  

   that 
  are 
  not 
  so 
  well 
  marked 
  from 
  Mr. 
  C. 
  A. 
  Hart, 
  The 
  specimens 
  from 
  

   Mr. 
  Hart 
  were 
  taken 
  near 
  Champaign, 
  Hlinois, 
  and 
  differ 
  from 
  the 
  

   others 
  in 
  having 
  the 
  red 
  coloration 
  almost 
  evenly 
  diffused 
  over 
  the 
  ver- 
  

   tex, 
  pronotum, 
  scutellum, 
  and 
  anterior 
  two- 
  thirds 
  of 
  the 
  elytra. 
  It 
  

   would 
  be 
  hard 
  to 
  recognize 
  this 
  form 
  as 
  belonging 
  to 
  obliqua 
  were 
  it 
  not 
  

   for 
  the 
  short 
  clypeus, 
  strongly 
  contracted 
  at 
  the 
  l)ase, 
  and 
  the 
  very 
  

   oblique 
  direction 
  of 
  the 
  inner 
  cross 
  nervure 
  of 
  the 
  elytron, 
  which 
  are 
  

   peculiarities 
  of 
  this 
  species.

  TYPHLOCYUA

  TYPHLOCYBA 
  ILLINOIENSIS, 
  new 
  species. 
  

  

  Color 
  whitish, 
  with 
  eyes 
  and 
  three 
  spots 
  on 
  elytra 
  black, 
  and 
  red 
  

  

  spots 
  on 
  head, 
  pronotum, 
  and 
  scutel- 
  

   lum; 
  length 
  3 
  mm. 
  

  

  This 
  species 
  is 
  whitish 
  or 
  pale 
  yel 
  

   low 
  throughout, 
  excei)t 
  the 
  eyes 
  and 
  

   the 
  red 
  and 
  black 
  spots, 
  which 
  are 
  

   distributed 
  as 
  follows 
  : 
  In 
  well-marked 
  

   specimens 
  there 
  is 
  a 
  bright 
  red 
  spot 
  

   on 
  the 
  vertex, 
  one 
  on 
  the 
  i^ronotum, 
  

   one 
  on 
  the 
  tip 
  of 
  the 
  scutellum, 
  a 
  few 
  

   very 
  minute 
  ones 
  on 
  the 
  bases 
  of 
  the 
  

   elytra, 
  and 
  one 
  on 
  the 
  mesopleura. 
  In 
  

   pale 
  specimens 
  all 
  of 
  these 
  may 
  be 
  absent 
  or 
  appearing 
  as 
  pale 
  yellow 
  

   spots, 
  the 
  one 
  on 
  the 
  scutellum 
  being 
  the 
  most 
  constant. 
  Each 
  elytron 
  

   has 
  three 
  distinct 
  black 
  spots, 
  one 
  midway 
  near 
  the 
  costal 
  margin, 
  one 
  

   at 
  the 
  base 
  of 
  the 
  inner 
  apical 
  cell, 
  and 
  one 
  between 
  the 
  third 
  tran- 
  

   verse 
  vein 
  aud 
  the 
  cla\'al 
  suture, 
  nearer 
  the 
  base 
  of 
  the 
  wing 
  than 
  to 
  

   the 
  transverse 
  nerves. 
  This 
  last 
  spot 
  is 
  usually 
  the 
  largest 
  aud 
  is 
  sur- 
  

   rounded 
  by 
  a 
  halo 
  of 
  red 
  or 
  yellow. 
  The 
  legs 
  are 
  whitish, 
  with 
  the 
  

   tibi;e 
  and 
  tarsi 
  more 
  or 
  less 
  tinged 
  with 
  pinkish 
  in 
  most 
  specimens. 
  

   The 
  tergum 
  is 
  also 
  often 
  tinged 
  with 
  reddish.
