  Under 
  the 
  genus 
  Bacunculus 
  Brunner 
  has 
  recorded 
  three 
  walking 
  

   sticks 
  as 
  occurring 
  in 
  our 
  fauna, 
  two 
  of 
  which 
  are 
  unknown 
  to 
  the 
  

   writer. 
  One 
  is 
  the 
  Bacteria 
  (Bacunculus) 
  striatus 
  of 
  Burmeister 
  and 
  

   the 
  others 
  are 
  ones 
  described 
  by 
  Brunner 
  as 
  new, 
  all 
  treated 
  as 
  species 
  

   of 
  Bacunculus 
  but 
  rightly 
  referable 
  to 
  the 
  older 
  generic 
  name 
  Hetero- 
  

   nemia 
  of 
  Gray. 
  Striatus 
  Burmeister 
  is 
  recorded 
  from 
  Texas, 
  another, 
  

   texanus, 
  is 
  described 
  from 
  the 
  same 
  State, 
  while 
  the 
  third, 
  Isevissimus, 
  

   is 
  described 
  from 
  St. 
  Louis 
  and 
  "Lacus 
  Ontario." 
  These 
  last 
  two 
  

   are 
  very 
  probably 
  synonyms 
  of 
  other 
  species, 
  but 
  until 
  the 
  types 
  are 
  

   seen 
  it 
  is 
  not 
  deemed 
  advisable 
  to 
  so 
  place 
  them. 
  The 
  last, 
  Isevissi- 
  

   7nus, 
  is 
  probably 
  a 
  young 
  female, 
  Diapheromera 
  femorata. 
  The 
  three 
  

   species 
  are 
  separated 
  as 
  follows 
  by 
  Brunner, 
  the 
  table 
  based 
  on 
  the 
  

   female:

  Pseudoseymyle 
  Caudell 
  has 
  had 
  one 
  species 
  added 
  since 
  the 
  revision 
  

   of 
  the 
  Phasmidse 
  of 
  the 
  United 
  States 
  in 
  1903 
  by 
  the 
  writer, 
  P. 
  tenuis, 
  

   having 
  been 
  described 
  from 
  Texas 
  in 
  1909 
  by 
  Rehn 
  and 
  Hebard. 
  

   This 
  species, 
  known 
  from 
  a 
  single 
  male 
  specimen, 
  is 
  closely 
  allied 
  to 
  

   P. 
  hanlcsii 
  Caudell, 
  No 
  better 
  table 
  for 
  the 
  separation 
  of 
  the 
  species 
  

   of 
  this 
  genus 
  than 
  those 
  in 
  the 
  above-mentioned 
  revision 
  have 
  been 
  

   made. 
  The 
  table 
  there 
  given 
  for 
  the 
  females 
  is 
  fairly 
  satisfactory, 
  

   but 
  the 
  males 
  are 
  more 
  diflficult, 
  and 
  the 
  character 
  of 
  comparative 
  

   length 
  given 
  for 
  the 
  separation 
  of 
  this 
  sex 
  of 
  hanlcsii 
  and 
  truncata 
  is 
  

   not 
  a 
  good 
  one. 
  

  

  The 
  original 
  description 
  of 
  HoplolihetJira 
  tuherculata 
  Caudell 
  states 
  

   that 
  the 
  hind 
  tibiae 
  are 
  provided 
  beneath 
  with 
  an 
  apical 
  areolate 
  area. 
  

   This 
  is 
  an 
  inexcusable 
  mistake, 
  there 
  being 
  no 
  trace 
  of 
  such 
  an 
  area. 
  

  

  The 
  later 
  described 
  Lihethra 
  confusa 
  of 
  Brunner 
  from 
  Mexico 
  seems 
  

   structurally 
  allied 
  to 
  Hoplolihethra 
  tuherculata, 
  but 
  the 
  measurements 
  

   given 
  for 
  it 
  does 
  not 
  seem 
  to 
  agree 
  very 
  well. 
  

  

  Parahacillus 
  palmeri 
  Caudell 
  described 
  from 
  Mexico 
  has 
  been 
  taken 
  

   within 
  our 
  borders, 
  specimens 
  in 
  the 
  U. 
  S. 
  National 
  Museum 
  from 
  

   Oklahoma 
  and 
  Arizona 
  being 
  referred 
  to 
  that 
  species. 
  The 
  diagnostic 
  

   character 
  of 
  the 
  long 
  legs 
  prove 
  variable, 
  and 
  so 
  this 
  species 
  is 
  reduced 
  

   to 
  varietal 
  rank. 
  

  

  In 
  my 
  revision 
  of 
  the 
  Phasmidse 
  I 
  included 
  the 
  first 
  description 
  of 
  

   Timema 
  califomica, 
  carefully 
  crediting 
  it 
  to 
  Scudder 
  and 
  quoting 
  his
