  Through 
  the 
  kindness 
  of 
  my 
  friend 
  Dr. 
  H. 
  Behr, 
  I 
  am 
  enabled 
  to 
  present 
  

   the 
  following 
  description 
  of 
  a 
  new 
  species 
  of 
  this 
  very 
  interesting 
  group 
  of 
  

   insects, 
  examples 
  of 
  which 
  are 
  contained 
  in 
  his 
  collection. 
  

  

  The 
  genus 
  Tkyris, 
  though 
  of 
  wide 
  geographical 
  distribution, 
  contains 
  but 
  

   few 
  forms, 
  and 
  perhaps 
  not 
  more 
  than 
  five 
  species 
  are 
  yet 
  known 
  to 
  science. 
  

   Of 
  these, 
  two 
  are 
  found 
  in 
  Europe, 
  one 
  in 
  India, 
  and 
  two 
  in 
  the 
  United 
  States. 
  

   The 
  species 
  now 
  noted 
  approaches 
  very 
  closely 
  in 
  coloration 
  to 
  the 
  European 
  

   forms, 
  but 
  is 
  in 
  many 
  respects 
  abundantly 
  distinct. 
  

  

  Thyris

  Primaries, 
  tawny, 
  palest 
  at 
  their 
  base, 
  with 
  four 
  waved 
  brownish 
  bands, 
  the 
  

   two 
  basal 
  narrow 
  and 
  very 
  irregular 
  in 
  form, 
  third 
  broadest, 
  notched 
  inwardly, 
  

   and 
  spreading 
  out 
  to 
  its 
  greatest 
  width 
  on 
  costa, 
  where 
  it 
  incloses 
  a 
  small 
  tri- 
  

   angular 
  yellow 
  patch. 
  Submarginal 
  band, 
  almost 
  equal. 
  On 
  the 
  disc 
  is 
  a 
  mi- 
  

   nute, 
  subovate, 
  vitreous 
  spot. 
  Fringes, 
  yellowish 
  brown. 
  

  

  Secondaries, 
  tawny, 
  with 
  brownish 
  blotches. 
  In 
  center 
  of 
  the 
  wing 
  is 
  a 
  large 
  

   vitreous 
  patch, 
  seemingly 
  two 
  oblong 
  patches 
  joined 
  together. 
  Fringes, 
  yel- 
  

   lowish 
  brown. 
  Underside, 
  same 
  as 
  the 
  upper, 
  with 
  the 
  brown 
  markings 
  a 
  little 
  

   darker 
  and 
  the 
  vitreous 
  patches 
  less 
  distinct.

  H. 
  Behr. 
  

  

  Nearly 
  allied 
  to 
  T. 
  fenestnita 
  of 
  Europe, 
  but 
  differing 
  by 
  its 
  paler 
  color, 
  and 
  

   by 
  the 
  smaller 
  size 
  of 
  the 
  vitreous 
  spots. 
  

  

  Specimens 
  of 
  Thyris

  Harris, 
  are 
  also 
  to 
  be 
  found 
  in 
  Dr. 
  Behr's 
  

   collection, 
  taken 
  in 
  the 
  same 
  locality 
  as 
  T. 
  montana. 
  

  

  Lake 
  Livingstone.

  H.

  HARKNESS,

  This 
  lake, 
  which 
  has 
  previously 
  been 
  visited 
  only 
  by 
  a 
  few 
  hunters, 
  is 
  situated 
  

   in 
  the 
  midst 
  of 
  mountains 
  of 
  high 
  altitude, 
  which 
  flank 
  Warner's 
  Valley 
  upon 
  

   the 
  north 
  and 
  Big 
  Meadows 
  upon 
  the 
  west. 
  In 
  general 
  outline 
  the 
  lake 
  is 
  in 
  

   the 
  form 
  of 
  a 
  triangle 
  measuring 
  one 
  and 
  three-fourths 
  miles 
  in 
  its 
  two 
  great- 
  

   est 
  diameters. 
  The 
  barometer 
  marked 
  an 
  altitude 
  of 
  7,330 
  feet 
  above 
  the 
  sea 
  

   level, 
  it 
  being, 
  as 
  I 
  believe, 
  the 
  most 
  elevated 
  of 
  any 
  body 
  of 
  water 
  of 
  such 
  

   magnitude 
  in 
  the 
  United 
  States, 
  although 
  there 
  are 
  many 
  lakes 
  in 
  the 
  vicinity 
  

   of 
  a 
  much 
  greater 
  elevation, 
  but 
  of 
  less 
  extent. 
  

  

  I 
  failed 
  to 
  detect 
  the 
  least 
  trace 
  of 
  fish, 
  or, 
  indeed, 
  of 
  any 
  animal 
  life 
  what-
