﻿470 
  BRITISH 
  LEPIDOPTERA. 
  

  

  the 
  spine3 
  are 
  extra 
  growths 
  interpolated 
  between 
  tubercles 
  i 
  and 
  ii. 
  

   It 
  must, 
  however, 
  be 
  noted 
  that, 
  in 
  some 
  Oxyptilid 
  pupse, 
  of 
  which 
  

   that 
  of 
  Oa-yptilits 
  parvidactyla 
  is 
  a 
  good 
  example, 
  the 
  pupa 
  has 
  the 
  

   spines 
  obsolescent 
  ; 
  in 
  0. 
  parvidactyla 
  they 
  exist 
  on 
  some 
  posterior 
  

   segments 
  ; 
  in 
  0. 
  laetus, 
  however, 
  they 
  are 
  quite 
  wanting.

  The 
  genus 
  Capperia 
  was 
  first 
  named 
  in 
  the 
  Ent. 
  Bee, 
  xvii., 
  p. 
  37, 
  

   when 
  heterodactyla 
  was 
  cited 
  as 
  the 
  type. 
  It 
  is 
  one 
  of 
  the 
  most 
  highly 
  

   specialised 
  of 
  the 
  genera 
  in 
  the 
  Oxyptilid 
  group, 
  if 
  not 
  in 
  the 
  whole 
  

   of 
  the 
  "plume" 
  fauna. 
  The 
  chief 
  characters 
  have 
  been 
  already 
  noted, 
  

   and 
  are 
  to 
  be 
  summarised 
  as 
  — 
  

  

  Imago 
  : 
  Palpi 
  slender, 
  second 
  joint 
  ascending 
  with 
  appressed 
  scales, 
  the 
  third 
  

   joint 
  very 
  slender 
  and 
  shorter 
  than 
  the 
  second, 
  the 
  fringes 
  of 
  the 
  outer 
  margin 
  of 
  the 
  

   second 
  lobe 
  with 
  a 
  white 
  dash 
  at 
  the 
  anal 
  angle. 
  The 
  genitalia 
  have 
  the 
  9th 
  and 
  

   10th 
  dorsal 
  plates 
  slender, 
  the 
  latter 
  being 
  small, 
  pointed, 
  and 
  hidden 
  on 
  the 
  9th 
  

   dorsal 
  plate; 
  the 
  9th 
  ventral 
  plate 
  very 
  strongly 
  developed, 
  as 
  long 
  as 
  the 
  prensors, 
  

   convex 
  below, 
  concave 
  above, 
  split 
  terminally 
  in 
  two 
  tips 
  or 
  points 
  ; 
  the 
  prensors 
  

   very 
  long, 
  narrow, 
  hollow 
  inside, 
  very 
  strongly 
  furnished 
  with 
  bristles 
  without 
  

   appendages 
  ; 
  the 
  penis 
  is 
  strongly 
  bent 
  downwards 
  before 
  and 
  behind, 
  terminating 
  

   in 
  two 
  strong 
  points, 
  a 
  shorter 
  and 
  longer. 
  

  

  Larva 
  : 
  Prothoracic 
  plate 
  with 
  many 
  secondary 
  hairs, 
  but 
  there 
  is 
  no 
  difficulty 
  in 
  

   distinguishing 
  the 
  usual 
  six 
  setse 
  on 
  each 
  side. 
  Body 
  deeply 
  segmented 
  ; 
  tubercles, 
  

   many-haired 
  warts 
  with 
  primary 
  and 
  secondary 
  hairs 
  ; 
  abdomen, 
  i 
  + 
  ii 
  forming 
  a 
  

   large 
  round 
  wart, 
  with 
  two 
  primary 
  hairs 
  ; 
  iii 
  also 
  a 
  large 
  wart 
  with 
  one 
  primary 
  

   hair 
  ; 
  iv 
  + 
  v 
  also 
  one 
  wart, 
  with 
  two 
  primaries, 
  that 
  representing 
  v 
  higher 
  than 
  the 
  

   other 
  ; 
  vi 
  has 
  one 
  primary 
  hair 
  ; 
  vii 
  three 
  primary 
  hairs 
  ; 
  behind 
  the 
  spiracle, 
  

   towards 
  back 
  of 
  segment, 
  two 
  accessory 
  warts 
  ; 
  skin 
  thickly 
  shagreened 
  with 
  blunt 
  

   skin-points 
  ; 
  many 
  minute 
  scattered 
  secondary 
  hairs, 
  broad 
  at 
  tips 
  ; 
  hooks 
  of 
  prolegs 
  

   well 
  developed, 
  

  

  Pupa: 
  Hairy 
  pupa 
  — 
  dorsal 
  spines 
  multiple 
  ; 
  hairs 
  on 
  appendages; 
  submedian 
  

   spines 
  on 
  each 
  side, 
  each 
  forming 
  a 
  bifid 
  process 
  of 
  which 
  each 
  branch 
  is 
  long 
  and 
  

   slender, 
  one 
  directed 
  forwards, 
  the 
  other 
  backwards 
  ; 
  good 
  cremaster. 
  

  

  Of 
  the 
  two 
  species 
  placed 
  by 
  Hofmann 
  (Deutsch. 
  Pteroph., 
  p. 
  116) 
  

   in 
  this 
  group, 
  he 
  notes 
  that 
  " 
  heterodactyla 
  is 
  to 
  be 
  distinguished 
  

   from 
  leonuri 
  by 
  the 
  darker 
  coloration 
  of 
  the 
  latter, 
  and 
  by 
  the 
  scale- 
  

   tuft 
  of 
  the 
  third 
  plumule, 
  in 
  which 
  the 
  isolated 
  group 
  of 
  scales 
  at 
  the
