   having 
  fallen 
  in 
  all 
  at

  Weather 
  preceding 
  this 
  rain 
  had 
  

   been 
  dry 
  enough 
  to 
  affect 
  the 
  growth 
  of 
  corn, 
  only 
  two 
  light 
  showers 
  

   having 
  occurred 
  in 
  July 
  and 
  these 
  early 
  in 
  the 
  month. 
  Railroad 
  

   traffic

  Bugs 
  in 
  corn 
  next 
  to 
  oats 
  quite 
  

   as 
  abundant 
  as

  of

  Now 
  a

  to 
  two

   bugs 
  on 
  a

  the 
  edges 
  of 
  the 
  field. 
  Adults 
  active, 
  a 
  

   great

  Many 
  young 
  just 
  hatched. 
  Very 
  few 
  dead 
  

   ones, 
  beating 
  rain 
  seeming 
  to 
  have 
  produced 
  no 
  marked 
  efPect. 
  A 
  

   few 
  freshly 
  dead 
  adults 
  were 
  seen 
  at 
  the 
  bases 
  of 
  the 
  leaves 
  next 
  the 
  

   stalks. 
  Ground 
  carefully 
  examined 
  for

   but 
  without 
  result. 
  None 
  seen 
  floating

  Weather 
  extremely 
  hot, 
  with 
  bright 
  suu. 
  No 
  rain

   last

  a 
  marked 
  diminution 
  in 
  number 
  of 
  bugs. 
  Adults 
  still 
  

   pairing. 
  Very 
  many 
  freshly 
  dead 
  adults 
  between 
  leaves 
  and 
  stalks 
  

   of 
  corn 
  in 
  the 
  field. 
  Only 
  a 
  few 
  of 
  these, 
  however, 
  showed 
  Sporo- 
  

   trichum, 
  and 
  none 
  Entomophthora. 
  Most 
  of 
  the 
  young 
  in 
  apparently 
  

   healthy 
  condition, 
  although 
  a 
  few 
  were 
  found 
  dead 
  with 
  Sporotrichum. 
  

  

  August

  From 
  a 
  collection 
  of 
  chinch-bugs 
  brought 
  in 
  from 
  

   Tamaroa 
  July 
  31, 
  all 
  dead, 
  individuals 
  were 
  selected 
  comprising 
  

   fifty-one 
  adults 
  and 
  about 
  fifteen 
  young, 
  with 
  two 
  more 
  adults 
  ami 
  

   one 
  young 
  in 
  a 
  dying 
  condition. 
  Twenty 
  adults 
  were 
  placed 
  on 
  

   damp 
  sand 
  under 
  cover, 
  the 
  remainder 
  being 
  retained 
  for 
  microscopic 
  

   examination. 
  One 
  of 
  the 
  two 
  dying 
  adults 
  lay 
  on 
  its 
  back 
  perfectly 
  

   helpless, 
  but 
  with 
  all 
  its 
  appendages 
  in 
  constant 
  tremor. 
  The 
  other 
  

   crawled 
  very 
  feebly 
  about. 
  This 
  collection 
  was 
  in 
  strong 
  contrast 
  

   with 
  those 
  made 
  at 
  the 
  same 
  time 
  at 
  Odin, 
  Edgewood. 
  and 
  Mattoon. 
  

   ill 
  respect 
  especially 
  to 
  the 
  large 
  number 
  of 
  dead 
  adults 
  in 
  the 
  Tama- 
  

   roa 
  lot.

  two 
  of 
  the 
  twenty 
  bugs 
  removed 
  to 
  damp 
  sand 
  

   exhibited 
  a 
  growth 
  of 
  SjJorofriclnuii 
  (jlohuliferuui. 
  But 
  one 
  addi- 
  

   tional
