  in 
  iEgeriids 
  for 
  instance) 
  ; 
  still, 
  the 
  undersurface 
  and 
  front 
  meet 
  here, 
  

   at 
  an 
  angle 
  of 
  about 
  85°. 
  The 
  thorax 
  (at 
  the 
  middle 
  of 
  the 
  meso- 
  

   thorax) 
  is 
  broader 
  and 
  higher 
  than 
  any 
  other 
  part 
  of 
  the 
  pupa, 
  but 
  

   so 
  slightly 
  that 
  it 
  would 
  be 
  almost 
  correct 
  to 
  say 
  it 
  is 
  of 
  the 
  same 
  width 
  

   from 
  here 
  to 
  the 
  3rd 
  abdominal. 
  There 
  is, 
  however, 
  a 
  slight 
  tapering 
  

   in 
  this 
  length, 
  but 
  no 
  bulbousness 
  of 
  the 
  thorax 
  as 
  in 
  the 
  pupae 
  of 
  some 
  

   Stenoptilias. 
  The 
  widtb 
  at 
  the 
  3rd 
  abdominal 
  segment 
  is 
  about 
  

   l-5mm., 
  of 
  the 
  4th 
  abdominal 
  segment 
  (without 
  appendages) 
  hardly 
  

   less, 
  and 
  it 
  thence 
  tapers 
  slightly 
  to 
  the 
  end 
  of 
  the 
  6th 
  abdominal 
  

   segment, 
  and 
  then 
  more 
  rapidly 
  to 
  the 
  point 
  of 
  the 
  cremastral 
  spine. 
  

   From 
  the 
  nose-spine 
  to 
  the 
  end 
  of 
  the 
  3rd 
  abdominal 
  segment, 
  to 
  which 
  

   the 
  appendages 
  are 
  fixed, 
  is 
  5mm. 
  ; 
  beyond 
  this, 
  the 
  free 
  appendages 
  

   (maxillae 
  and 
  second 
  and 
  third 
  tarsi) 
  extend 
  2mm., 
  and 
  are 
  accom- 
  

   panied 
  by 
  the 
  special 
  wing-tips 
  for 
  nearly 
  half 
  the 
  distance. 
  The 
  first 
  

   tarsi 
  reach 
  to 
  the 
  end 
  of 
  the 
  3rd 
  abdominal 
  segment 
  (to 
  the 
  end 
  of 
  

   the 
  wings, 
  without 
  tips) 
  ; 
  the 
  antennae 
  l-5mm. 
  less. 
  The 
  maxillae 
  

   disappear 
  beneath 
  the 
  first 
  legs 
  a 
  little 
  higher 
  up, 
  at 
  2*6mm. 
  from 
  

   their 
  base, 
  to 
  reappear 
  again 
  in 
  the 
  free 
  appendage-process. 
  The 
  

   first 
  femora 
  do 
  not 
  appear, 
  and 
  only 
  the 
  minutest, 
  narrow, 
  triangular 
  

   piece 
  of 
  labium. 
  The 
  mandibles 
  meet 
  in 
  the 
  middle 
  line 
  for 
  a 
  short 
  

   distance 
  ; 
  the 
  labrum 
  is 
  thus 
  short 
  and 
  obtuse, 
  but 
  with 
  a 
  sharp 
  

   point. 
  There 
  appears 
  to 
  be 
  one 
  (very 
  minute) 
  hair 
  on 
  the 
  face 
  ; 
  none 
  

   are 
  detected 
  on 
  the 
  labrum 
  or 
  at 
  the 
  antennal 
  bases. 
  They 
  may, 
  

   however, 
  be 
  present, 
  as, 
  in 
  these 
  unmounted 
  specimens, 
  those 
  on 
  the 
  

   eye-covers 
  are 
  quite 
  invisible 
  till 
  got 
  into 
  profile. 
  The 
  eye-covers 
  have 
  

   two 
  hairs 
  of 
  approximately 
  the 
  length 
  already 
  given 
  ; 
  the 
  covers 
  are 
  

   circular, 
  apart 
  from 
  the 
  flat 
  edge 
  against 
  the 
  antennae, 
  and 
  have 
  the 
  

   eye-facets 
  as 
  fine 
  points 
  round 
  the 
  margin. 
  The 
  small 
  prothoracic 
  

   piece, 
  tolerably 
  closely 
  attached 
  to 
  the 
  mesothorax, 
  is 
  connected 
  (on 
  

   dehiscence) 
  to 
  the 
  eye- 
  piece 
  by 
  a 
  long 
  membrane, 
  of 
  which 
  a 
  slight 
  

   fold 
  may 
  be 
  the 
  dorsal 
  head-piece 
  ; 
  the 
  prothorax, 
  membrane, 
  and 
  

   eye-piece 
  (as 
  in 
  the 
  dehisced 
  pupa, 
  not 
  stretched 
  out 
  but 
  bent 
  

   and 
  twisted) 
  are 
  about 
  065mm. 
  in 
  length, 
  divided 
  so 
  that, 
  of 
  

   five 
  parts, 
  two 
  are 
  prothorax, 
  two 
  membrane, 
  and 
  one 
  eye-piece. 
  

   The 
  prothoracic 
  spiracle-cover 
  (on 
  mesothorax) 
  is 
  like 
  those 
  of 
  others 
  

   of 
  the 
  same 
  genus, 
  forming 
  a 
  little 
  arched 
  hood 
  (longest 
  in 
  line 
  of 
  

   incision), 
  beautifully 
  ornamented 
  with 
  microscopic 
  spicules 
  or 
  hairs, 
  

   which 
  differ 
  a 
  little 
  in 
  size 
  and 
  arrangement 
  from 
  one 
  end 
  of 
  

   the 
  cover 
  to 
  the 
  other. 
  The 
  mesothorax 
  opens 
  by 
  a 
  dorsal 
  suture 
  on 
  

   dehiscence 
  ; 
  the 
  metathorax 
  remains 
  undivided. 
  The 
  dorsal 
  ridges 
  

   hardly 
  affect 
  the 
  prothorax, 
  but 
  cross 
  the 
  mesothorax, 
  are 
  rather 
  wide 
  

   apart 
  and 
  high 
  in 
  front 
  (where 
  they 
  have 
  already 
  been 
  alluded 
  to 
  as 
  

   giving 
  a 
  straight 
  outline 
  to 
  the 
  front), 
  lower 
  and 
  approximate, 
  towards 
  

   the 
  metathorax. 
  On 
  the 
  metathorax 
  they 
  begin 
  a 
  little 
  further 
  apart 
  

   than 
  they 
  were 
  at 
  the 
  posterior 
  border 
  of 
  the 
  mesothorax, 
  and 
  gradu- 
  

   ally 
  get 
  further 
  apart 
  till 
  they 
  terminate 
  before 
  the 
  posterior 
  border 
  of 
  

   the 
  3rd 
  abdominal 
  segment. 
  They 
  are 
  low 
  and 
  rounded, 
  but 
  still 
  quire 
  

   pronounced. 
  There 
  is 
  a 
  slight 
  hollow, 
  plaoed 
  dorsal 
  to 
  the 
  wings, 
  deepest 
  

   at 
  the 
  1st 
  abdominal 
  segment, 
  whereit 
  would 
  form 
  a 
  waist, 
  but 
  that 
  it 
  

   does 
  not 
  affect 
  the 
  dorsal 
  line 
  appreciably. 
  The 
  wings 
  are 
  rather 
  

   polished, 
  but 
  show 
  some 
  of 
  the 
  neuration. 
  In 
  this, 
  and 
  in 
  a 
  good 
  many 
  

   other 
  "plume" 
  pupa 
  1 
  1 
  have 
  examined, 
  the 
  wings 
  contain 
  a 
  large 
  number 
  

   of 
  the 
  imaginal 
  scales, 
  torn 
  from 
  the 
  wing 
  in 
  emerging, 
  so 
  that 
  the
