  Comparison 
  of 
  the 
  Platyptiliin^:, 
  Eucnemidophorinje, 
  Amblyptiliin^, 
  

   and 
  marasmarchinie. 
  

   The 
  Platyptiliinae 
  are 
  essentially 
  a 
  subfamily 
  with 
  internal-feeding 
  

   larvae, 
  recognised, 
  in 
  the 
  larval 
  stage, 
  by 
  the 
  absence 
  of 
  the 
  depression 
  

   of 
  the 
  prothoracic 
  scutellum 
  ; 
  by 
  an 
  abundance 
  of 
  unjointed 
  secondary 
  

   skin-hairs, 
  in 
  addition 
  to 
  the 
  usual 
  skin-points 
  or 
  spiculae; 
  the 
  presence 
  

   of 
  simple, 
  tapering, 
  primary 
  setae 
  ; 
  the 
  arrangement 
  of 
  tubercles 
  i 
  and 
  ii 
  

   in 
  a 
  transverse 
  line 
  on 
  the 
  meso- 
  and 
  metathorax 
  ; 
  the 
  separation 
  of 
  setae 
  

   iv 
  and 
  v 
  although 
  on 
  a 
  common 
  basal 
  plate 
  ; 
  the 
  absence 
  of 
  the 
  accessory 
  

   postspiracular 
  tubercles, 
  and 
  the 
  unraised 
  character 
  of 
  the 
  spiracles. 
  

   The 
  pupal 
  characters 
  are 
  as 
  distinctly 
  marked, 
  inasmuch 
  as 
  there 
  is 
  a 
  

   poor 
  development 
  (or 
  absence) 
  of 
  the 
  anterior 
  portion 
  of 
  the 
  cremastral 
  

   hooks, 
  while 
  the 
  pupal 
  skin 
  is 
  smooth, 
  the 
  setae 
  microscopic 
  and 
  clubbed, 
  

   the 
  nose-horn 
  well-developed, 
  the 
  dorsal 
  ridge 
  prominent, 
  and 
  the 
  

   posterior 
  portion 
  of 
  the 
  abdominal 
  segments 
  rough 
  dorsally. 
  The 
  

   Eucnemidophorinae, 
  Amblyptiliinae, 
  and 
  Marasmarchinae, 
  on 
  the 
  other 
  

   hand, 
  are 
  peculiar, 
  in 
  that 
  they 
  have 
  larvae 
  that 
  are 
  internal- 
  feeders 
  in 
  

   their 
  earliest 
  stadia 
  (i.e., 
  to 
  the 
  hybernating 
  period), 
  more 
  or 
  less 
  external 
  

   and 
  exposed 
  feeders 
  in 
  their 
  later 
  stadia 
  (i.e., 
  after 
  hybernation) 
  ; 
  the 
  

   depression 
  of 
  the 
  prothoracic 
  scutellum 
  is 
  generally 
  well-marked, 
  often 
  

   strongly 
  pigmented; 
  the 
  secondary 
  skin-hairs 
  are 
  variable 
  in 
  size, 
  markedly 
  

   knobbed, 
  or 
  swollen, 
  at 
  tip; 
  the 
  primary 
  setae 
  smooth, 
  blunt 
  or 
  swollen 
  

   at, 
  or 
  just 
  before, 
  tip; 
  the 
  setae 
  accompanied 
  by 
  secondary 
  hairs, 
  living- 
  

   rise 
  to 
  incipient 
  wart-structure; 
  those 
  of 
  i 
  and 
  ii 
  conjoined 
  on 
  either 
  side 
  

   on 
  meso- 
  and 
  metathorax 
  ; 
  of 
  iv 
  and 
  v 
  also 
  with 
  conjoined 
  bases 
  ; 
  tubercle 
  

   vi 
  usually 
  single-haired 
  ; 
  the 
  accessory 
  postspiracular 
  tubercles 
  usually 
  

   indicated, 
  or 
  more 
  or 
  less 
  weakly 
  developed; 
  the 
  spiracles 
  rather 
  raised. 
  

   The 
  pupal 
  characters 
  are 
  as 
  characteristic; 
  both 
  portions 
  of 
  the 
  cremaster 
  

   are 
  well- 
  supplied 
  with 
  hooks; 
  the 
  skin, 
  though 
  smooth, 
  bears 
  well- 
  

   developed 
  primary 
  setae 
  (almost 
  of 
  the 
  same 
  form 
  as 
  those 
  of 
  the 
  larva) 
  ; 
  

   the 
  nose-horn 
  evanescent, 
  or 
  absent 
  ; 
  the 
  dorsal 
  ridge 
  variable 
  (e\ 
  anoscent
