  The 
  following 
  notes 
  on 
  the 
  male 
  type 
  of 
  this 
  species 
  are 
  copied 
  

   from 
  my 
  notebook 
  as 
  written 
  a 
  few 
  months 
  ago: 
  "The 
  male 
  type 
  

   has 
  the 
  cerci 
  convex 
  outwardly 
  and 
  deeply 
  concave 
  inwardly. 
  The 
  

   niQth 
  segment 
  of 
  the 
  abdomen 
  is 
  about 
  two 
  times 
  as 
  long 
  as 
  broad, 
  

   parallel 
  sided, 
  and 
  posteriorly 
  broadly 
  notched, 
  the 
  entire 
  length 
  

   about 
  equaling 
  that 
  of 
  the 
  cerci; 
  eighth 
  segment 
  two- 
  thirds 
  as 
  long 
  

   as 
  the 
  ninth, 
  of 
  the 
  same 
  width 
  posteriorly 
  and 
  broadening 
  a 
  little 
  

   anteriorly; 
  seventh 
  segment 
  about 
  the 
  same 
  length 
  as 
  the 
  ninth 
  and 
  

   of 
  the 
  same 
  width 
  posteriorly 
  as 
  the 
  anterior 
  width 
  of 
  the

   ment, 
  the 
  anterior 
  part 
  gently 
  narrowing.

  The 
  following 
  notes 
  on 
  the 
  unique 
  male 
  type 
  of 
  D. 
  Carolina 
  are 
  from 
  

   my 
  note 
  book: 
  ''Cerci 
  strongly 
  incurved 
  and 
  much 
  flattened, 
  being 
  

   fully 
  twice 
  as 
  thick 
  vertically 
  as 
  horizontally, 
  broadened 
  slightly 
  

   toward 
  the 
  apex; 
  outwardly 
  the 
  cerci 
  are 
  convex 
  and 
  inwardly, 
  espe- 
  

   cially 
  in 
  the 
  apical 
  portion, 
  concave, 
  nearly 
  spoon-shaped; 
  no 
  basal 
  

   cereal 
  tooth 
  visible. 
  Ninth 
  segment 
  of 
  the 
  abdomen 
  globose 
  no 
  

   longer 
  than 
  the 
  posterior 
  width. 
  Seventh 
  and 
  eighth 
  segments 
  of 
  

   abdomen 
  equal 
  in 
  length, 
  each 
  slightly 
  broader 
  than 
  long 
  and 
  neither 
  

   quite 
  as 
  long 
  as 
  the 
  ninth 
  segment." 
  

  

  The 
  Scudder 
  collection 
  contains 
  a 
  pair 
  of 
  walking 
  sticks 
  which 
  I 
  

   consider 
  as 
  probably 
  belonging 
  here 
  in 
  which 
  the 
  cerci 
  of 
  the 
  male 
  

   are 
  more 
  concave 
  inwardly 
  than 
  those 
  of 
  the 
  type. 
  The 
  cerci 
  of 
  this 
  

   female 
  are 
  as 
  long 
  as 
  the 
  eighth 
  segment 
  of 
  the 
  abdomen 
  and 
  concave 
  

   on 
  the 
  inside. 
  The 
  eighth 
  segment 
  of 
  the 
  abdomen 
  is 
  apparently 
  a 
  

   fourth 
  shorter 
  than 
  the 
  ninth. 
  These 
  were 
  evidently 
  preserved 
  in 
  

   spirits 
  and 
  are 
  considerably 
  shriveled. 
  They 
  are 
  labeled 
  "Palmer 
  

   Assorting 
  No. 
  1032." 
  This, 
  according 
  to 
  a 
  note 
  book 
  shown 
  me 
  by 
  

   Mr. 
  Henshaw, 
  means 
  "Pacific

  The 
  genus 
  Rhahdoceratites 
  of 
  Rehn 
  and 
  Hebard 
  is 
  closely 
  allied 
  to 
  

   Diapheromera, 
  but 
  the 
  head 
  being 
  armed 
  with 
  a 
  small 
  pair 
  of 
  horns, 
  

   or 
  spurs, 
  will 
  serve 
  to 
  separate 
  it 
  from 
  that 
  genus. 
  The 
  only 
  species 
  

   recorded 
  from 
  our 
  fauna 
  is 
  R. 
  covillese 
  Rehn 
  and 
  Hebard, 
  described 
  

   in 
  1909 
  from 
  Texas. 
  In 
  1906 
  I 
  took 
  nymphs 
  at 
  Ciudad 
  Juarez, 
  

   Mexico, 
  on 
  creosote 
  bushes, 
  but 
  failed 
  to 
  rear 
  adults. 
  The 
  Shudder 
  

   collection 
  contains 
  a 
  female 
  from 
  New 
  Mexico. 
  About 
  the 
  middle 
  of 
  

   September, 
  1912, 
  Mr. 
  C. 
  K. 
  Gray 
  sent 
  to 
  the 
  United 
  States 
  National 
  

   Museum 
  a 
  female 
  of 
  this 
  species 
  which 
  had 
  freshly 
  matured, 
  the 
  old 
  

   skin 
  being 
  but 
  partially 
  cast. 
  A 
  month 
  later 
  three 
  pairs 
  of 
  this 
  fine 
  

   insect 
  were 
  received 
  from 
  the 
  same 
  gentleman, 
  all 
  being 
  taken 
  from 
  

   creosote 
  bushes 
  at 
  El 
  Paso, 
  Texas. 
  The 
  eggs 
  of 
  this 
  species, 
  a 
  number 
  

   of 
  which 
  were 
  found 
  in 
  the 
  box 
  with 
  the 
  living 
  insects, 
  are 
  very 
  like 
  

   those 
  of 
  Diapheromera, 
  but 
  appear 
  to 
  be 
  more 
  fragile 
  and 
  are 
  decidedly
