  A 
  new 
  species 
  of 
  North 
  American 
  Tingitidae, 
  Gargaphia 
  solani, 
  

   is 
  described 
  from 
  specimens 
  obtained 
  from 
  Kirkwood, 
  Mo., 
  

   on 
  Solanum 
  carolinense 
  and 
  S. 
  elaeagnifolium 
  ; 
  from 
  Lavaca 
  Co., 
  

   Texas, 
  on 
  coffee 
  weed 
  and 
  Solanum 
  ; 
  from 
  El 
  Reno, 
  Okla., 
  and 
  

   Norfolk, 
  Va. 
  This 
  species 
  is 
  found 
  on 
  egg-plants 
  and 
  potatoes 
  in 
  

   great 
  abundance, 
  and 
  seems 
  to 
  have 
  a 
  wide 
  range 
  of 
  distribution 
  

   from 
  the 
  Atlantic 
  coast 
  to 
  the 
  South-Western 
  States.

  The 
  larvae 
  of 
  Melanotus 
  communis 
  and 
  Agriotes 
  mancus 
  were 
  

   responsible 
  for 
  the 
  destruction 
  of 
  much 
  sown 
  maize. 
  Clover 
  was 
  badly 
  

   affected 
  by 
  the 
  clover 
  Chalcid, 
  Bruchophagus 
  funebris, 
  the 
  clover-root 
  

   borer, 
  Hylastinus 
  obscurus, 
  and 
  the 
  clover 
  mite, 
  Bryobia 
  pratensis. 
  

   B. 
  funebris 
  larvae 
  were 
  only 
  found 
  in 
  the 
  seed 
  of 
  the 
  common 
  red 
  

   and 
  mammoth 
  red 
  clovers 
  ; 
  adults 
  were 
  observed 
  flying 
  about 
  the 
  

   heads 
  of 
  the 
  alsike 
  clover, 
  but 
  no 
  grubs 
  were 
  obtained 
  from 
  this 
  

   variety. 
  The 
  grubs 
  were 
  first 
  observed 
  in 
  the 
  red 
  clover 
  seed 
  in 
  July, 
  

   at 
  which 
  time 
  no 
  adults 
  could 
  be 
  found 
  about 
  the 
  heads. 
  In 
  the 
  

   laboratory, 
  adults 
  began 
  to 
  emerge 
  about 
  the 
  middle 
  of 
  July, 
  and 
  

   after 
  that, 
  and 
  throughout 
  the 
  greater 
  part 
  of 
  August, 
  they 
  were 
  

   present 
  in 
  large 
  numbers, 
  depositing 
  their 
  eggs 
  in 
  the 
  young 
  seeds. 
  

   In 
  many 
  heads 
  examined 
  in 
  small 
  experimental 
  plots 
  there 
  was 
  com- 
  

   plete 
  failure 
  to 
  ripen 
  seed, 
  although 
  most 
  of 
  the 
  flowers 
  had 
  been 
  

   f 
  ertihsed. 
  A 
  small 
  Chalcid 
  parasite 
  was 
  reared 
  from 
  the 
  clover-leaf 
  midge, 
  

   Dasyneura 
  trifolii, 
  which 
  was 
  quite 
  common 
  on 
  the 
  leaves 
  of 
  white 
  

   clover. 
  The 
  turnip 
  flea-beetle, 
  Phyllotreta 
  vittata, 
  was 
  abundant 
  in 
  

   the 
  rootfields, 
  and 
  early 
  in 
  the 
  season 
  did 
  much 
  injury 
  to 
  young 
  

   turnips. 
  Considerable 
  damage 
  was 
  caused 
  among 
  radishes 
  by 
  the 
  

   wavy 
  flea-beetle, 
  P. 
  sinuata, 
  which 
  seems 
  not 
  to 
  have 
  been 
  

   previously 
  reported 
  as 
  a 
  pest 
  in 
  Quebec 
  Province. 
  

  

  Potatoes 
  suffered 
  severely 
  from 
  the 
  flea-beetles, 
  Epitrix 
  cucumeris 
  

   and 
  Systena 
  hudsoniae. 
  Pieris 
  rapae 
  was 
  extremely 
  abundant 
  on 
  

   cabbage 
  and 
  other 
  cruciferous 
  plants, 
  but 
  its 
  parasites, 
  chief 
  among
