  Elytron 
  of 
  typhlocyba 
  tenerrima. 
  

  

  the 
  cross 
  nervures, 
  and 
  the 
  extremities 
  of 
  the 
  outer 
  cross 
  nervure 
  and 
  

   of 
  the 
  iuner 
  and 
  outer 
  apical 
  nervures 
  are 
  black; 
  the 
  tip 
  of 
  the 
  ovi- 
  

   positor 
  and 
  the 
  basal 
  portion 
  of 
  the 
  tergum 
  of 
  the 
  abdomen 
  are 
  also 
  

   black; 
  aside 
  from 
  the 
  dark 
  compound 
  eyes, 
  these 
  are 
  the 
  only 
  mark- 
  

   ings. 
  (See 
  Fig. 
  145.) 
  

  

  Specimens 
  of 
  this 
  species 
  were 
  sent 
  me 
  by 
  Professor 
  i\. 
  C. 
  Davis. 
  

   One 
  lot 
  was 
  labeled, 
  "Ag. 
  

   Coll. 
  Mich., 
  9/23/'92, 
  460," 
  and 
  

   another 
  lot, 
  "Ag. 
  Coll. 
  Mich., 
  

   9/17/"95, 
  on 
  wild 
  grape." 
  I 
  

   found 
  it 
  rather 
  common 
  on 
  

   hazelnut 
  {Corylus 
  rostrata) 
  in 
  

   Colorado, 
  in 
  Clear 
  Creek 
  Canon, 
  above 
  Golden, 
  July 
  18, 
  and 
  in 
  the 
  

   foothills 
  near 
  Palmer 
  Lake, 
  August 
  12, 
  1896. 
  

  

  TYPHLOCYBA 
  LETHIERRYI 
  Edwards. 
  

  

  I 
  have 
  not 
  seen 
  the 
  original 
  description 
  of 
  this 
  species, 
  but 
  deter- 
  

   mined 
  the 
  specimens 
  that 
  I 
  have 
  by 
  comparison 
  with 
  European 
  speci- 
  

   mens 
  loaned 
  me 
  by 
  Mr. 
  E. 
  P. 
  Van 
  Duzee. 
  I 
  also 
  sent 
  specimens 
  to 
  

   Doctor 
  Melichar, 
  who 
  determined 
  them 
  T. 
  lethierryi, 
  so 
  there 
  can 
  be 
  

   little 
  doubt 
  as 
  to 
  the 
  correctness 
  of 
  the 
  determinations. 
  The 
  species 
  

   is 
  described 
  by 
  Doctor 
  Melichar 
  along 
  with 
  the 
  preceding. 
  

  

  The 
  si)ecies 
  resembles 
  T. 
  ros(c 
  very 
  closely, 
  but 
  is 
  sulphurous 
  yellow 
  

   in 
  color 
  instead 
  of 
  pale 
  yellow 
  or 
  whitish. 
  The 
  color 
  is 
  deepest 
  on 
  the 
  

   elytra 
  where 
  it 
  stops 
  abruptly 
  at, 
  or 
  a 
  little 
  in 
  front 
  of, 
  the 
  cross- 
  

   nervures, 
  and 
  the 
  palest 
  yellow 
  is 
  beneath. 
  The 
  dark 
  eyes 
  and 
  black 
  

  

  tip 
  of 
  the 
  ovipositor 
  are 
  the 
  

   only 
  markings. 
  (See 
  Fig. 
  146.) 
  

   The 
  only 
  specimens 
  of 
  this 
  

   species 
  that 
  I 
  have 
  seen 
  from 
  

   America 
  were 
  a 
  few 
  samples 
  

   sent 
  by 
  Professor 
  G. 
  C. 
  Davis, 
  

   labeled, 
  "Ag. 
  Coll. 
  Mich., 
  

   7/5/'92," 
  and 
  a 
  good 
  number 
  sent 
  me 
  by 
  Mr. 
  E. 
  D. 
  Bell, 
  labeled 
  "Ames, 
  

   Iowa, 
  June 
  19, 
  from 
  hard 
  maple."
