  I 
  do 
  not 
  have 
  access 
  to 
  the 
  description 
  of 
  this 
  species 
  by 
  Linnaeus, 
  

   and 
  so 
  give 
  the 
  following 
  brief 
  characterization 
  by 
  Harris: 
  

  

  Ou 
  rose. 
  * 
  * 
  * 
  In 
  its 
  perfect 
  state 
  it 
  is 
  rather 
  less 
  than 
  three- 
  twentieths 
  of 
  an 
  

   inch 
  long. 
  Its 
  body 
  is 
  yellowish 
  white, 
  its 
  wing 
  covers 
  and 
  wiugs 
  are 
  white 
  and 
  

   transparent, 
  and 
  its 
  eyes, 
  claws, 
  and 
  piercer 
  brown. 
  The 
  male 
  has 
  two 
  recnrved 
  

   appendages 
  at 
  the 
  tip 
  of 
  its 
  hind 
  body. 
  It 
  maybe 
  called 
  Tettigonia 
  rosiv. 
  (See 
  Figs.

  Doctor 
  Gustav 
  Flor, 
  in 
  Khynchoten 
  Livlands 
  (Cicadiua 
  uud 
  Psyl- 
  

   lodea),' 
  says 
  that 
  this 
  species 
  is 
  sometimes 
  golden 
  yellow 
  in 
  color 
  to 
  

   near 
  the 
  elytra, 
  and 
  that 
  the 
  males 
  are 
  2.^ 
  and 
  the 
  females 
  2^ 
  mm. 
  in 
  

   length. 
  He 
  also 
  says 
  that 
  it 
  is 
  abundant 
  on 
  rose 
  and 
  also 
  upon 
  linden 
  

   from 
  August 
  to 
  late 
  in 
  October. 
  

  

  This 
  is 
  a 
  very 
  widespread 
  and 
  common 
  species. 
  Specimens 
  in 
  my 
  col- 
  

   lection 
  from 
  Europe, 
  and 
  from 
  ocean 
  to 
  ocean 
  in 
  this 
  country, 
  seem 
  to 
  

   be 
  identical, 
  the 
  chief 
  variation 
  being 
  in 
  size. 
  Specimens 
  

   that 
  I 
  have 
  studied 
  vary 
  from 
  3.25 
  to 
  3J 
  mm. 
  in 
  length. 
  

   The 
  only 
  dark 
  markings 
  that 
  I 
  have 
  seen 
  are 
  those 
  men- 
  

   tioned 
  by 
  Harris 
  in 
  his 
  description, 
  but 
  I 
  find 
  that 
  the 
  

   males 
  frequently 
  have 
  the 
  upi^er 
  portion 
  of 
  the 
  face 
  

  

  bright 
  orange 
  in 
  color. 
  

  

  Professor 
  G. 
  C. 
  Davis 
  sent 
  me 
  

   specimens 
  of 
  this 
  speiie.s 
  that 
  he 
  

   took 
  at 
  the 
  Michigan 
  Agricul- 
  

   tural 
  College 
  on 
  apple, 
  plum, 
  

   tame 
  cherry, 
  currant, 
  and 
  grape. 
  

   Mr. 
  Pergande 
  sent 
  me 
  specimens 
  

   that 
  he 
  took 
  in 
  the 
  District 
  of 
  

   Columbia 
  on 
  apple, 
  and 
  I 
  have 
  

   received 
  specimens 
  from 
  Mr. 
  

   Samuel 
  Henshaw, 
  marked 
  " 
  Mass. 
  

   on 
  rose," 
  and 
  others 
  from 
  the 
  Illi- 
  

   nois 
  State 
  Laboratory 
  of 
  Natural 
  History 
  from 
  grape 
  (10819). 
  Speci- 
  

   mens 
  sent 
  me 
  from 
  the 
  U. 
  S. 
  National 
  Museum 
  were 
  labeled 
  as 
  follows: 
  

   "Ft. 
  Collins, 
  Colo., 
  Sep. 
  4th, 
  on 
  apple, 
  J. 
  Cassidy." 
  " 
  Burlington, 
  Yt., 
  

   on 
  apple." 
  " 
  Iowa, 
  Gillette." 
  I 
  have 
  specimens 
  from 
  Corfield, 
  Van- 
  

   couver 
  Island, 
  taken 
  on 
  rose 
  by 
  Mr. 
  Clermont 
  Livingstone, 
  where 
  they 
  

   are 
  evidently 
  abundant. 
  

  

  I 
  have 
  taken 
  the 
  species 
  in 
  this 
  State 
  at 
  Denver 
  and 
  Fort 
  Collins 
  on 
  

   apple, 
  at 
  Manitou 
  on 
  oak, 
  and 
  at 
  Fort 
  Collins 
  on 
  cotton 
  wood.
