  shifted 
  its 
  quarters, 
  and 
  was 
  observed 
  nearly 
  buried 
  beneath 
  the 
  

   skin, 
  at 
  no 
  great 
  distance 
  from 
  its 
  companion, 
  and 
  later 
  in 
  the 
  day 
  

   both 
  were 
  completely 
  out 
  of 
  sight. 
  

  

  The 
  other 
  larva, 
  B., 
  which 
  had 
  two 
  hexapous 
  placed 
  upon 
  it 
  

   at 
  3 
  p.m., 
  one 
  of 
  which 
  had 
  taken 
  up 
  its 
  position 
  on 
  the 
  breast, 
  

   was 
  found 
  at 
  5 
  p. 
  m., 
  having 
  this 
  half-buried 
  beneath 
  the 
  skin, 
  

   the 
  remaining 
  portion 
  recumbent, 
  and 
  attached 
  outside. 
  The 
  

   second 
  hexapod 
  had 
  fixed 
  itself 
  upon 
  a 
  lobe 
  of 
  the 
  head, 
  near 
  

   the 
  raentum, 
  from 
  which 
  I 
  was 
  unable 
  to 
  detach 
  it 
  ; 
  but 
  it 
  sub- 
  

   sequently 
  removed, 
  and 
  in 
  the 
  morning 
  was 
  nowhere 
  to 
  be 
  found, 
  

   while 
  the 
  first 
  had 
  entirely 
  and 
  deeply 
  penetrated 
  within. 
  

  

  Other 
  hexapods, 
  placed 
  upon 
  a 
  soft 
  yellow 
  Polisles 
  pupa, 
  left 
  

   this 
  unmolested.

  About 
  a 
  week 
  later, 
  viz., 
  on 
  the 
  24th, 
  seeing 
  little 
  prospect 
  of 
  

   rearing 
  the 
  said 
  PoUstes 
  larvae, 
  to 
  which 
  I 
  had 
  administered 
  in 
  

   the 
  interval 
  moistened 
  sugar, 
  diluted 
  honey, 
  fruit, 
  &c., 
  with 
  no 
  

   appearance 
  of 
  relish 
  on 
  their 
  part, 
  I 
  determined 
  to 
  institute 
  a 
  

   search 
  for 
  the 
  hexapods 
  within, 
  in 
  order 
  to 
  ascertain 
  what 
  their 
  

   condition 
  might 
  be. 
  On 
  carefully 
  opening 
  B, 
  and 
  removing 
  a 
  

   dark 
  globular 
  mass, 
  which 
  is 
  always 
  met 
  with 
  in 
  those 
  larvae, 
  I 
  

   found 
  the 
  hexapod 
  which 
  had 
  penetrated 
  on 
  the 
  17th 
  and 
  18th, 
  

   in 
  a 
  somewhat 
  distended 
  condition, 
  perfectly 
  motionless, 
  the 
  head 
  

   deflexed, 
  the 
  anterior 
  segments 
  humped, 
  and 
  obviously 
  preparing 
  

   to 
  undergo 
  its 
  first 
  moult, 
  as 
  seen 
  in 
  the 
  silkworm. 
  

  

  In 
  about 
  half 
  an 
  hour, 
  I 
  observed 
  that 
  the 
  juices 
  of 
  the 
  

   PoUstes 
  larva 
  were 
  rapidly 
  inspissating, 
  while 
  the 
  hexapod 
  itself 
  

   appeared 
  to 
  have 
  undergone 
  some 
  alteration 
  ; 
  and 
  on 
  further 
  

   examination, 
  I 
  perceived 
  that 
  the 
  latter 
  was 
  then 
  in 
  the 
  act 
  of 
  

   discarding 
  its 
  hexapod 
  skin, 
  the 
  anterior 
  portion 
  being 
  now 
  

   pellucid 
  white, 
  without 
  any 
  trace 
  of 
  legs, 
  furnished 
  with 
  two 
  

   minute 
  but 
  very 
  distinctly 
  marked 
  black 
  eyes, 
  and 
  having 
  the 
  

   lower 
  region 
  still 
  enveloped 
  in 
  the 
  fuscous 
  folds 
  of 
  the 
  hexapod. 
  

  

  During 
  the 
  day, 
  I 
  also 
  opened 
  the 
  other 
  PoUstes 
  larva. 
  A, 
  

   and 
  soon 
  found 
  the 
  two 
  hexapods 
  which 
  had 
  penetrated 
  on 
  the 
  

   18th, 
  — 
  one 
  having 
  its 
  head 
  turned 
  towards 
  the 
  anal 
  extremity, 
  

   the 
  other 
  lying 
  transversely 
  ; 
  neither, 
  however, 
  having 
  undergone 
  

   any 
  metamorphosis,

  Stale. 
  

  

  It 
  would 
  seem, 
  from 
  the 
  foregoing 
  remarks, 
  that 
  the 
  position 
  of 
  

   the 
  Strepsipterous 
  larvae 
  in 
  the 
  incipient 
  stage 
  exhibits 
  no 
  uni- 
  

   formity, 
  and 
  that 
  the 
  hexapods 
  indiscriminately 
  attack 
  any 
  part 
  

   of 
  their 
  victims, 
  although 
  eventually 
  restricted 
  to 
  the 
  abdo-
