  The 
  author 
  deals 
  with 
  the 
  elm 
  aphids 
  of 
  the 
  Eastern 
  United 
  States 
  

   belonging 
  to 
  the 
  genus 
  Schizoneura. 
  Among 
  the 
  points 
  of 
  specific 
  

   value 
  in 
  separating 
  these 
  aphids 
  are 
  the 
  antennae 
  of 
  the 
  stem 
  females, 
  

   the 
  wax 
  glands 
  of 
  the 
  apterous 
  generations 
  and 
  the 
  antenna! 
  characters 
  

   of 
  the 
  winged 
  females. 
  The 
  habitat 
  and 
  the 
  species 
  of 
  the 
  elm 
  con- 
  

   cerned 
  are 
  also 
  of 
  much 
  significance. 
  Among 
  the 
  species 
  considered 
  

   in 
  this 
  bulletin 
  is 
  the 
  woolly 
  aphid 
  of 
  elm 
  bark, 
  S. 
  rileyi. 
  It 
  is 
  not 
  

   uncommon 
  to 
  find 
  the 
  trunks 
  and 
  branches 
  of 
  young 
  elms 
  with 
  the 
  

   tender 
  places 
  in 
  the 
  bark 
  closely 
  packed 
  with 
  colonies 
  of 
  this 
  species. 
  

   Descriptions 
  of 
  the 
  distinguishing 
  features 
  of 
  the 
  different 
  generations 
  

   are 
  given, 
  the 
  antennae 
  especially 
  being 
  described 
  and 
  illustrated. 
  

   Elm 
  rosette 
  or 
  leaf-cluster 
  aphid, 
  S. 
  lanigera, 
  and 
  the 
  northern 
  curl 
  

   of 
  American 
  elm, 
  S. 
  americana, 
  are 
  here 
  treated 
  separately, 
  though 
  

   the 
  author 
  states 
  that 
  there 
  seems 
  to 
  be 
  no 
  ground 
  for 
  separating 
  the 
  

   two 
  except 
  the 
  nature 
  of 
  their 
  elm 
  habitat 
  [see 
  this 
  Review, 
  Ser. 
  A, 
  i, 
  

   pp. 
  24-26.] 
  The 
  author 
  also 
  notes 
  that 
  the 
  life-cycle 
  of 
  the 
  leaf- 
  

   roller 
  of 
  elms, 
  S. 
  ulmi, 
  includes 
  a 
  residence 
  on 
  the 
  roots 
  of 
  currants 
  and 
  

   gooseberries, 
  the 
  form 
  which 
  occurs 
  onRibes 
  being 
  known 
  as 
  S.fodiens. 
  

   Specimens 
  identical 
  with 
  S. 
  ulmi 
  (fodiens) 
  have 
  been 
  collected 
  in 
  

   Cahfornia, 
  Oregon, 
  Maine 
  and 
  Ontario. 
  

  

  The 
  Bulletin 
  concludes 
  with 
  a 
  food-plant 
  catalogue 
  of 
  the 
  Aphididae 
  

   of 
  the 
  world.
