  In 
  the 
  groups 
  of 
  plates 
  this 
  insect 
  resembles 
  A. 
  cucullus, 
  Gr. 
  It 
  also 
  has 
  affinities 
  

   with 
  Morganella 
  maskelli, 
  but 
  differs 
  from 
  both 
  in 
  the 
  presence 
  of 
  circumgenital 
  

   pores, 
  and 
  in 
  the 
  median 
  lobes 
  being 
  fused. 
  On 
  the 
  whole, 
  however, 
  I 
  think 
  it 
  is 
  

   more 
  nearly 
  allied 
  to 
  Howardia 
  biclavis, 
  Comst. 
  

  

  Lepidosaphes 
  erythrinae, 
  sp. 
  nov. 
  

  

  Female 
  scale 
  about 
  2 
  mm. 
  long 
  ; 
  exuviae 
  at 
  one 
  end 
  golden-brown 
  ; 
  secretion 
  

   very 
  dark 
  brown. 
  

  

  Male 
  scale 
  similar, 
  but 
  smaller 
  ; 
  white 
  in 
  region 
  of 
  " 
  hinge 
  " 
  and 
  often 
  caudad 
  

   of 
  " 
  hinge." 
  

  

  Adult 
  elongated 
  ; 
  cephalothorax 
  large, 
  sides 
  straight, 
  tapering 
  slightly 
  towards 
  

   the 
  anterior 
  end, 
  which 
  is 
  rounded. 
  Antenna 
  consisting 
  of 
  a 
  tubercle 
  bearing 
  1 
  or 
  

   2 
  long 
  setae 
  ; 
  in 
  one 
  case 
  one 
  of 
  the 
  setae 
  is 
  deeply 
  forked. 
  Anterior 
  spiracles 
  with 
  

   1 
  or 
  2 
  parastigmatic 
  glands, 
  posterior 
  one 
  without 
  such 
  glands. 
  A 
  single 
  pair 
  of 
  

   lobes, 
  resembling 
  somewhat 
  in 
  shape 
  the 
  lobes 
  of 
  Howardia 
  biclavis, 
  Comst. 
  ; 
  they 
  

   are 
  prominent, 
  somewhat 
  triangular 
  in 
  shape, 
  but 
  not 
  symmetrically 
  so, 
  the 
  apex 
  

   being 
  much 
  nearer 
  to 
  the 
  mesal 
  side 
  ; 
  the 
  mesal 
  margin 
  is 
  slightly 
  curved, 
  with 
  

   a 
  notch 
  near 
  the 
  apex 
  ; 
  the 
  lateral 
  margin 
  straight, 
  minutely 
  but 
  distinctly 
  

   serrated. 
  A 
  large 
  triangular 
  chitinous 
  area 
  extends 
  into 
  the 
  pygidium 
  from 
  the 
  base 
  

   of 
  each 
  lobe. 
  The 
  other 
  lobes 
  are 
  rudimentary, 
  being 
  represented 
  by 
  small 
  serrated 
  

   projections. 
  Between 
  the 
  median 
  lobes, 
  a 
  pair 
  of 
  plates, 
  a 
  pair 
  of 
  setae, 
  and 
  a 
  small 
  

   spinous 
  process. 
  There 
  is 
  also 
  a 
  small 
  seta 
  on 
  the 
  base 
  of 
  the 
  median 
  lobes. 
  

   Laterad 
  of 
  the 
  median 
  lobes 
  in 
  the 
  following 
  order 
  : 
  — 
  a 
  plate 
  ; 
  a 
  gland-pore, 
  with 
  

   a 
  short 
  spine-like 
  extension 
  ; 
  two 
  setae, 
  the 
  mesal 
  one 
  of 
  which 
  is 
  situated 
  over 
  

   the 
  serrated 
  projection 
  which 
  occupies 
  the 
  position 
  of 
  second 
  lobe 
  ; 
  two 
  long 
  plates, 
  

   the 
  lateral 
  one 
  of 
  which 
  is 
  associated 
  with 
  a 
  gland 
  pore 
  ; 
  a 
  gland 
  pore 
  ; 
  a 
  seta 
  ; 
  two 
  

   long 
  plates 
  with 
  a 
  seta 
  between 
  them 
  ; 
  two 
  gland 
  pores 
  ; 
  a 
  seta 
  ; 
  two 
  plates 
  with 
  

   a 
  seta 
  between 
  them 
  ; 
  one 
  gland 
  pore. 
  The 
  marginal 
  pores 
  are 
  long 
  and 
  narrow. 
  

   The 
  segments 
  in 
  front 
  of 
  the 
  pygidium 
  bear 
  two 
  or 
  three 
  plates 
  on 
  their 
  margins. 
  

   The 
  anus 
  is 
  situated 
  cephalad 
  of 
  the 
  median 
  group 
  of 
  circumgenital 
  pores.

   had

  Dorsal 
  pores 
  small,

  two 
  bands 
  on 
  each 
  side 
  of 
  

   pygidium, 
  the 
  mesal 
  band 
  being 
  mesad 
  of 
  the 
  lateral 
  groups 
  of 
  circumgenital 
  pores. 
  

   The 
  median 
  lobes 
  of 
  the 
  second 
  exuvium 
  are 
  distinct 
  and 
  of 
  the 
  same 
  shape 
  as 
  

   those 
  of 
  the 
  adult.
