  the 
  abdominal 
  region, 
  which 
  is 
  crippled 
  and 
  distorted 
  also 
  to 
  a 
  

   considerable 
  extent 
  by 
  the 
  desiccated 
  conical 
  pupa-cases 
  of 
  the 
  

   male 
  parasite, 
  but 
  apparently 
  scarcely 
  incommoded 
  by 
  the 
  pres- 
  

   sure 
  of 
  the 
  female. 
  

  

  Mr. 
  Newport 
  indeed 
  on 
  one 
  occasion, 
  when 
  only 
  a 
  single 
  spe- 
  

   cimen 
  of 
  a 
  female 
  Stylops 
  had 
  been 
  nurtured, 
  found 
  the 
  oviducts 
  

   of 
  the 
  bee 
  " 
  of 
  ordinary 
  length 
  and 
  size, 
  but 
  the 
  ovaries 
  entirely 
  

   undeveloped, 
  and 
  scarcely 
  larger 
  than 
  they 
  are 
  at 
  the 
  period 
  when 
  

   the 
  bee-larva 
  passes 
  to 
  the 
  state 
  of 
  nymph. 
  They 
  contained 
  only 
  

   the 
  germs 
  of 
  a 
  few 
  very 
  imperfect 
  ova."* 
  

  

  On 
  the 
  other 
  hand, 
  when 
  speaking 
  of 
  the 
  manner 
  in 
  which 
  the 
  

   hexapod 
  larvae 
  of 
  Stylops 
  are 
  transferred 
  to 
  the 
  cells 
  of 
  their 
  

   victims, 
  he 
  observes, 
  " 
  they 
  cling 
  fast 
  to 
  the 
  hairs 
  on 
  the 
  body 
  of 
  

   the 
  wasp 
  or 
  bee 
  in 
  which 
  they 
  have 
  been 
  hatched, 
  and 
  are 
  trans- 
  

   ported 
  by 
  the 
  insect 
  to 
  its 
  nest."t 
  And 
  again, 
  "the 
  Stylops 
  

   hatched 
  within 
  its 
  parent 
  in 
  the 
  abdomen 
  of 
  the 
  bee, 
  issues 
  forth 
  

   and 
  clings 
  to 
  the 
  hairs 
  which 
  cover 
  the 
  body 
  of 
  the 
  fated 
  insect, 
  

   and 
  thus 
  at 
  once 
  has 
  a 
  means 
  of 
  conveyance 
  on 
  the 
  bee 
  to 
  her 
  

   nest, 
  in 
  which 
  it 
  is 
  to 
  be 
  fed." 
  J 
  

  

  These 
  remarks, 
  which 
  necessarily 
  assume 
  the 
  victim 
  to 
  be 
  

   capable 
  of 
  constructing 
  brood-cells, 
  and 
  of 
  depositing 
  eggs 
  

   therein, 
  are 
  in 
  perfect 
  unison 
  with 
  Dr. 
  Siebold's 
  views 
  upon 
  this 
  

   subject, 
  as 
  expounded 
  under 
  his 
  seventh 
  result, 
  wherein 
  he 
  states, 
  

   " 
  Die 
  sechsbeinigen 
  Strepsipteren-Larven 
  kriechen 
  auf 
  dem 
  Ab- 
  

   domen 
  der 
  Hymenopteren, 
  in 
  welchen 
  ihre 
  mutter 
  wohnen, 
  munter 
  

   umher. 
  Diese 
  Strepsipteren-Larven 
  lassen 
  sich 
  auf 
  diese 
  weise 
  

   in 
  die 
  nester 
  der 
  Hyinenopteren 
  tragen, 
  wo 
  sie 
  alsdann 
  gelegenheit 
  

   finden, 
  sich 
  durch 
  die 
  weichen 
  Korper-Bedeckungen 
  der 
  Hyme- 
  

   nopteren-Larven 
  hindurch 
  zu 
  arbeiten, 
  und 
  in 
  die 
  Leibeshohle 
  

   derselben 
  zu 
  gelangen."§ 
  

  

  If, 
  indeed, 
  in 
  accordance 
  with 
  the 
  opinion 
  first 
  suggested 
  by 
  

   Kirby, 
  and 
  generally 
  assented 
  to 
  by 
  others, 
  as 
  to 
  the 
  probable 
  

   effects 
  upon 
  the 
  reproductive 
  powers 
  in 
  the 
  case 
  of 
  the 
  male 
  para- 
  

   sites, 
  the 
  same 
  results 
  be 
  also 
  attributable 
  to 
  the 
  females, 
  and 
  

   their 
  hexapod 
  progeny 
  consequently 
  be 
  always 
  dependent 
  upon 
  

   fortuitous 
  means 
  of 
  access 
  to 
  the 
  larva-cells 
  of 
  prolific 
  individuals 
  ; 
  

   the 
  circumstance 
  of 
  the 
  subsequent 
  co-ordination 
  of 
  the 
  sexes 
  in 
  

   these 
  parasites, 
  indiscriminately 
  dispersed 
  in 
  the 
  first 
  instance 
  and 
  

   assembled 
  at 
  random 
  afterwards, 
  could 
  only 
  be 
  ascribed 
  to 
  some
