  To 
  the 
  excellent 
  account 
  of 
  this 
  insect 
  given 
  by 
  Professor 
  Weed 
  we 
  

   have 
  nothing 
  to 
  add 
  save 
  a 
  few 
  notes 
  as 
  to 
  its 
  occurrence 
  at 
  Saranac 
  

   Inn. 
  The 
  imago 
  was 
  not 
  observed 
  at 
  all 
  outside 
  our 
  breeding 
  cages. 
  

   Larvae 
  and 
  pupae 
  were 
  obtained 
  in 
  several 
  places 
  about 
  the 
  shores 
  of 
  

   Little 
  Clear 
  pond. 
  

  

  June 
  14 
  Dr 
  Felt 
  and 
  I, 
  while 
  looking 
  over 
  the 
  ground 
  preparatory 
  to 
  

   beginning 
  regular 
  operations, 
  rowed 
  into 
  the 
  little 
  bay 
  on 
  the 
  west 
  side 
  of 
  

   Blueberry 
  island 
  in 
  Little 
  Clear 
  pond 
  and 
  found 
  the 
  species 
  in 
  abundance. 
  

   The 
  bank 
  was 
  overhung 
  with 
  clumps 
  of 
  fragrant 
  Labrador 
  tea, 
  and 
  here 
  

   and 
  there 
  lay 
  a 
  rotting 
  hemlock 
  log 
  half 
  in 
  the 
  water 
  and 
  half 
  out, 
  the 
  

   exposed 
  portion 
  bearing 
  an 
  ornamental 
  covering 
  of 
  matted 
  moss 
  and 
  

   sundew 
  plants. 
  Our 
  boat 
  touched 
  shore 
  beside 
  one 
  of 
  these 
  logs; 
  and 
  

   there 
  was 
  a 
  hole 
  in 
  the 
  rotten 
  wood, 
  with 
  an 
  empty 
  pupa 
  skin 
  hanging 
  

   out 
  of 
  it. 
  We 
  followed 
  this 
  clue, 
  and, 
  examining 
  the 
  log, 
  found 
  the 
  

   Chauliodes 
  pupae. 
  By 
  pulling 
  apart 
  the 
  crumbling 
  fragments 
  with 
  

   our 
  fingers, 
  we 
  in 
  a 
  very 
  little 
  while 
  found 
  in 
  this 
  and 
  a 
  few 
  other 
  logs 
  

   near 
  by, 
  25 
  pupae. 
  One 
  of 
  these 
  transformed 
  on 
  the 
  way 
  home, 
  and 
  the 
  

   imago 
  was 
  lost 
  ; 
  three 
  were 
  raised 
  ; 
  a 
  number 
  were 
  preserved 
  for 
  specimens, 
  

   and 
  the 
  remainder 
  died. 
  On 
  the 
  i6th 
  I 
  returned 
  to 
  this 
  place 
  again, 
  

   and 
  found 
  that 
  by 
  this 
  time 
  many 
  had 
  transformed. 
  There 
  were 
  still 
  

   plenty 
  of 
  pupae 
  to 
  be 
  found, 
  however, 
  by 
  diligent 
  searching 
  of 
  the 
  partly 
  

   submerged 
  and 
  crumbhng 
  logs. 
  

  

  Chauliodes 
  eggs, 
  which 
  I 
  took 
  to 
  belong 
  to 
  this 
  species, 
  were 
  not 
  

   uncommonly 
  found 
  attached 
  to 
  the 
  flat 
  surface 
  of 
  some 
  old, 
  gray 
  snagx)r 
  

   board 
  several 
  feet 
  above 
  the 
  surface 
  of 
  the 
  water. 
  They 
  were 
  more 
  

   grayish 
  in 
  color 
  than 
  the 
  eggs 
  of 
  Ch. 
  serricornis, 
  and 
  were 
  ar- 
  

   ranged 
  in 
  somewhat 
  more 
  regular 
  V-shaped 
  rows, 
  and 
  never 
  more 
  than 
  

   one 
  layer 
  in 
  depth. 
  I 
  saw 
  a 
  number 
  of 
  clusters 
  about 
  July 
  i 
  on 
  the 
  

   side 
  of 
  the 
  boathouse 
  facing 
  the 
  pond. 
  These, 
  as 
  well 
  as 
  the 
  clusters
