  (8). 
  Mamestra 
  hrassicce. 
  I 
  had 
  not 
  more 
  than 
  half-a- 
  

   dozen 
  pupEe 
  of 
  this 
  species, 
  and 
  only 
  two 
  of 
  them 
  

   emerged, 
  and 
  the 
  same 
  day, 
  the 
  17th 
  March, 
  on 
  our 
  

   homeward 
  voyage 
  between 
  Singapore 
  and 
  Trincomalee. 
  

   This 
  is 
  a 
  moth 
  I 
  should 
  have 
  thought 
  would 
  have 
  been 
  

   earlier 
  affected. 
  

  

  (9). 
  Pelurc/a 
  comitata. 
  I 
  obtained 
  about 
  four 
  dozen 
  

   larvae 
  of 
  this 
  species 
  feeding 
  upon 
  Chenopodium 
  at 
  

   Chatham 
  in 
  September, 
  1890, 
  but 
  not 
  a 
  single 
  moth 
  

   appeared 
  during 
  the 
  cruise, 
  and 
  I 
  imagined 
  that 
  the 
  

   pupae 
  had 
  all 
  perished. 
  However, 
  on 
  the 
  11th 
  August, 
  

   at 
  Sheerness, 
  a 
  fine 
  female 
  emerged. 
  The 
  larvae 
  were 
  

   fed 
  up 
  in 
  a 
  large 
  wide-mouthed 
  bottle, 
  and 
  on 
  the 
  6th 
  

   September, 
  as 
  I 
  required 
  the 
  bottle 
  for 
  other 
  larvae, 
  I 
  

   shook 
  out 
  the 
  contents, 
  and 
  was 
  surprised 
  to 
  find 
  over 
  

   two 
  dozen 
  healthy-looking 
  pupas, 
  which 
  evidently 
  intend 
  

   to 
  lie 
  over 
  to 
  next 
  season. 
  I 
  may 
  add 
  that 
  we 
  left 
  

   Sheerness 
  on 
  the 
  14th 
  August 
  for 
  Bermuda 
  and 
  Halifax, 
  

   where 
  we 
  had 
  some 
  hot 
  weather, 
  and 
  returned 
  to 
  Ports- 
  

   mouth 
  on 
  the 
  25th 
  instant. 
  

  

  The 
  number 
  of 
  species 
  experimented 
  upon 
  were 
  not 
  

   sufficient 
  to 
  enable 
  any 
  important 
  conclusions 
  to 
  be 
  

   drawn, 
  although 
  it 
  would 
  appear 
  that 
  a 
  tolerably 
  quick 
  

   change 
  from 
  a 
  very 
  cold 
  to 
  a. 
  very 
  warm 
  climate 
  induces 
  

   early 
  hatching 
  ; 
  but 
  that 
  different 
  species 
  are 
  differently 
  

   affected, 
  Eupithecia 
  sind 
  Iladena, 
  for 
  instance, 
  appearing 
  

   before 
  Tcsniocampa, 
  and 
  Pelurga* 
  being 
  in 
  no 
  way 
  

   influenced. 
  

  

  It 
  is 
  an 
  interesting 
  subject, 
  and 
  I 
  hope 
  to 
  be 
  able 
  to 
  

   carry 
  out 
  experiments 
  on 
  a 
  larger 
  scale 
  during 
  the 
  

   coming 
  winter.

  H.M.S.

  Portland,

   My 
  dear 
  Sir, 
  — 
  Since 
  I 
  sent 
  that 
  little 
  paper 
  I 
  have 
  bred 
  two 
  

   Pelurga 
  comitata, 
  one 
  on 
  30th 
  September, 
  the 
  other 
  on 
  1st 
  inst., 
  

   from 
  the 
  larvae 
  found 
  thirteen 
  months 
  ago. 
  They 
  are 
  very 
  eccentric 
  

   in 
  their 
  manner 
  of 
  appearance. 
  Perhaps 
  you 
  would 
  kindly 
  add 
  a 
  

   footnote 
  to 
  my 
  paper, 
  and 
  oblige 
  yours, 
  in 
  great 
  haste, 
  

  

  H. 
  Goss, 
  Esq. 
  Gervase 
  F. 
  Mathew.
