  indicated 
  that 
  there 
  was 
  probably 
  an 
  additional 
  molting 
  prior 
  to 
  pupa- 
  

   tion, 
  but 
  the 
  rearing 
  of 
  the 
  species 
  later 
  by 
  Dr 
  Packard 
  seems 
  to 
  show 
  

   conclusively 
  that 
  there 
  are 
  but 
  four 
  molts 
  — 
  the 
  same 
  number 
  found 
  by 
  

   Mr 
  Edwards 
  (see 
  citation). 
  

  

  During 
  the 
  following 
  month 
  (September 
  1869), 
  from 
  the 
  7th 
  to 
  the 
  

   1 
  6th, 
  T4 
  individuals 
  were 
  taken 
  by 
  me, 
  and 
  as 
  many 
  more 
  by 
  Mr 
  Meske, 
  

   of 
  Albany, 
  from 
  the 
  lower 
  branches 
  of 
  a 
  number 
  of 
  pines 
  {Finns 
  strobns) 
  

   bordering 
  a 
  road 
  in 
  the 
  Forbes 
  manor, 
  at 
  Bath. 
  Their 
  presence 
  on 
  a 
  

   tree 
  was 
  in 
  most 
  instances 
  readily 
  revealed 
  by 
  the 
  large 
  pellets 
  of 
  their 
  

   excrement 
  lying 
  upon 
  the 
  smooth 
  gravelled 
  road 
  beneath, 
  when, 
  from 
  the 
  

   robust 
  form 
  of 
  the 
  larva 
  in 
  marked 
  contrast 
  with 
  the 
  slender 
  leaves 
  sur- 
  

   rounding 
  it, 
  its 
  resting 
  place 
  was 
  not 
  difficult 
  to 
  detect. 
  On 
  the 
  7th 
  one 
  

   was 
  taken 
  which 
  had 
  just 
  completed 
  its 
  last 
  molting; 
  on 
  the 
  9th 
  one 
  was 
  

   observed 
  in 
  the 
  process 
  of 
  molting, 
  which, 
  from 
  some 
  irregularity 
  

   attending 
  it, 
  had 
  fallen 
  to 
  the 
  ground 
  ; 
  and 
  on 
  the 
  same 
  day 
  one 
  which 
  

   had 
  already 
  assumed 
  the 
  brown 
  or 
  tawny 
  hue 
  indicative 
  of 
  its 
  full 
  

   maturity 
  was 
  taken 
  while 
  moving 
  down 
  the 
  trunk 
  of 
  a 
  tree 
  to 
  seek 
  its 
  

   place 
  for 
  pupation. 
  The 
  most 
  advanced 
  one 
  of 
  the 
  others 
  collected 
  

   matured 
  on 
  the 
  nth, 
  and 
  transformed 
  to 
  a 
  pupa 
  on 
  the 
  surface 
  of 
  the 
  

   ground 
  on 
  the 
  i6th 
  of 
  the 
  month. 
  Most 
  of 
  the 
  remainder 
  entered 
  

   the 
  ground, 
  where 
  they 
  constructed 
  cells 
  of 
  moderate 
  dimensions 
  for 
  

   their 
  pupal 
  transformation. 
  

  

  The 
  pupae 
  were 
  kept 
  in 
  a 
  cold 
  room 
  during 
  the 
  winter, 
  and 
  about 
  

   March 
  i 
  were 
  removed 
  to 
  a 
  warm 
  apartment. 
  April 
  28, 
  May 
  3 
  and 
  7, 
  

   male 
  imagos 
  emerged, 
  after 
  which 
  females 
  were 
  disclosed 
  till 
  near 
  the 
  

   end 
  of 
  the 
  month. 
  Dr 
  Dyar 
  reports 
  (see 
  citation) 
  that 
  from 
  June 
  20 
  

   to 
  August 
  4, 
  40 
  examples 
  of 
  the 
  moth 
  were 
  captured 
  at 
  electric 
  lights 
  in 
  

   Poughkeepsie, 
  N. 
  Y., 
  of 
  which 
  r6 
  were 
  taken 
  on 
  July 
  9. 
  

  

  In 
  September 
  1870, 
  diligent 
  search 
  was 
  again 
  made 
  for 
  the 
  larva 
  in 
  

   the 
  locality 
  at 
  Bath, 
  where 
  it 
  had 
  been 
  abundant 
  the 
  preceding 
  year, 
  as 
  

   above 
  recorded, 
  without 
  finding 
  a 
  single 
  individual. 
  Its 
  non-occurrence 
  

   indicates 
  a 
  marked 
  periodicity 
  in 
  the 
  appearance 
  of 
  the 
  species 
  or, 
  possi- 
  

   bly, 
  an 
  exhausted 
  locality 
  from 
  the 
  collections 
  made. 
  

  

  Description 
  of 
  the 
  egg". 
  The 
  following 
  is 
  Dr 
  Packard's 
  description 
  

  

  of 
  the 
  egg 
  of 
  this 
  insect 
  : 
  

  

  Length, 
  3 
  mm; 
  breadth, 
  2.5 
  mm; 
  thickness, 
  2 
  mm. 
  Flattened 
  ellip- 
  

   tic, 
  ends 
  alike, 
  white, 
  with 
  an 
  equatorial, 
  smooth, 
  distinct 
  ridge. 
  

   The 
  shell 
  is 
  white, 
  the 
  surface 
  under 
  a 
  high 
  power 
  triplet 
  is 
  seen 
  to 
  be 
  

   finely 
  pitted, 
  the 
  pits 
  being 
  shallow 
  and 
  not 
  closely 
  crowded. 
  Under 
  a 
  

   half-inch 
  objective 
  the 
  pits 
  are 
  seen 
  to 
  be 
  shallow, 
  and 
  not 
  often 
  with 
  a 
  

   definite 
  raised 
  edge: 
  often 
  there 
  is 
  a 
  boss 
  or 
  bead 
  in 
  the 
  center.
