  fig

  a), 
  the 
  latter 
  lying 
  obliquely 
  to 
  one 
  side 
  of 
  the 
  median 
  line 
  in 
  mounted 
  pre- 
  

   parations. 
  Clypeus 
  (fig. 
  1, 
  a, 
  cl.) 
  strongly 
  produced, 
  densely 
  hairy 
  and 
  com- 
  

   pletely 
  overlying 
  the 
  mentum. 
  Antennae, 
  legs 
  and 
  thoracic 
  stigmata 
  lying 
  in 
  very 
  deep 
  

   -depressions. 
  Ventrally 
  the 
  margins 
  and 
  the 
  whole 
  of 
  the 
  thoracic 
  area, 
  together 
  with 
  

   the 
  terminal 
  abdominal 
  segment, 
  densely 
  hairy 
  ; 
  the 
  hairs 
  (fig. 
  1, 
  d) 
  distinctly 
  knobbed 
  

   at 
  the 
  tips. 
  Antennae 
  (fig. 
  1, 
  a, 
  an) 
  robust, 
  of 
  8-9 
  strongly 
  chitinised 
  segments. 
  

   Legs 
  (fig. 
  1, 
  a) 
  robust, 
  and 
  strongly 
  chitinised 
  ; 
  claw 
  simple. 
  Abdominal 
  stigmata 
  

   small 
  and 
  apparently 
  in 
  six 
  pairs. 
  Thoracic 
  stigmata 
  large 
  ; 
  the 
  gland-pores 
  mul- 
  

   tilocular, 
  the 
  cylindrical 
  ducts 
  long 
  and 
  apparently 
  truncate 
  proximally. 
  Dermal 
  

   gland-pores 
  (fig. 
  1, 
  /) 
  large 
  and 
  with 
  a 
  deep 
  cylindrical 
  rim 
  ; 
  they 
  are 
  irregularly 
  

   •disposed 
  on 
  the 
  venter 
  and 
  for 
  a 
  short 
  distance 
  also 
  beyond 
  the 
  margii 
  ; 
  the 
  dorsum 
  

   rather 
  thickly 
  studded 
  with 
  minute 
  pores 
  surrounded 
  by 
  dark 
  granular 
  bodies. 
  

   Anus 
  large 
  and 
  roughly 
  circular 
  in 
  the 
  outline 
  formed 
  by 
  the 
  dense 
  chitinous 
  walls 
  

   of 
  the 
  body 
  ; 
  no 
  other 
  exact 
  details 
  observed, 
  but 
  portions 
  of 
  a 
  ruptured 
  

   membranous 
  cuticle 
  project 
  into 
  the 
  lumen, 
  suggesting 
  that 
  the 
  true 
  structure 
  is 
  

   wanting. 
  Diameter, 
  6'5-9mm. 
  ; 
  antennae, 
  0*6 
  mm. 
  long. 
  

  

  Larva. 
  Form 
  elongate. 
  Antennae 
  (fig. 
  1, 
  b) 
  clavate, 
  of 
  six 
  segments 
  ; 
  2nd, 
  4th, 
  

   and 
  6th 
  longest 
  ; 
  3rd 
  and 
  5th 
  very 
  short 
  and 
  sub 
  equal 
  ; 
  all 
  the 
  segments 
  with 
  fine 
  

   slender 
  hairs, 
  the 
  longer 
  ones 
  less 
  than 
  the 
  length 
  of 
  the 
  terminal 
  segment 
  ; 
  terminal 
  

   segment 
  with 
  several 
  slender 
  spinose 
  hairs 
  at 
  the 
  tip 
  ; 
  in 
  the 
  clear 
  membrane 
  which 
  

   connects 
  the 
  2nd 
  and 
  3rd 
  segments 
  is 
  a 
  relatively 
  very 
  large 
  chitinous 
  ring 
  with 
  a 
  

   granular 
  centre 
  ; 
  as 
  no 
  hair 
  or 
  spine 
  has 
  been 
  seen 
  attached 
  to 
  this 
  organ 
  it 
  is 
  

   suggested 
  that 
  it 
  may 
  be 
  a 
  sensorium 
  or 
  gland-pore 
  ; 
  three 
  similar 
  structures 
  also 
  

   occur 
  on 
  the 
  coxae. 
  Legs 
  long 
  and 
  slender 
  ; 
  claw 
  (fig. 
  1, 
  c) 
  with 
  a 
  minute, 
  

   subapical 
  denticle. 
  Dorsal 
  gland-pores 
  with 
  a 
  broad 
  quoit-like 
  rim 
  and 
  a 
  very 
  short 
  

   cylindrical 
  duct, 
  the 
  whole 
  structure 
  when 
  seen 
  in 
  profile 
  reminding 
  one 
  of 
  a 
  very 
  

   short-stemmed 
  agaric 
  or 
  broad-flanged 
  stopper 
  to 
  a 
  g]ass 
  jar 
  ; 
  these 
  are 
  arranged 
  

   more 
  or 
  less 
  in 
  transverse 
  rows. 
  The 
  terminal 
  segments 
  of 
  the 
  abdomen, 
  more 
  

   •especially 
  in 
  the 
  region 
  of 
  the 
  anus, 
  with 
  a 
  group 
  of 
  large 
  spines, 
  packed 
  very 
  closely 
  

   together 
  in 
  the 
  median 
  area. 
  Terminal 
  abdominal 
  bristles 
  in 
  five 
  pairs 
  ; 
  these 
  are 
  

   of 
  great 
  length, 
  or 
  slightly 
  longer 
  than 
  the 
  antennae. 
  The 
  chitinised 
  hind 
  gut 
  with 
  

   its 
  flange-like 
  papillae 
  very 
  distinct. 
  Abdomen 
  with 
  at 
  least 
  six 
  pairs 
  of 
  stigmata 
  ; 
  

   the 
  external 
  opening 
  minute 
  and 
  membranous 
  ; 
  the 
  atrium 
  long, 
  gradually 
  

   narrowed 
  distally, 
  strongly 
  ribbed 
  transversely 
  or 
  irregularly 
  moniliform, 
  and 
  the 
  

   proximal 
  portion 
  with 
  a 
  deep 
  wide 
  cleft 
  ; 
  the 
  connective 
  tube 
  slender, 
  chitinised, 
  

   and 
  bifurcated, 
  each 
  branch 
  having 
  well-formed 
  taenidia 
  ; 
  length 
  of 
  the 
  atrium 
  

   about 
  twice 
  the 
  diameter 
  of 
  the 
  large 
  quoit-like 
  gland-pores.

  The 
  determination 
  of 
  the 
  species 
  is 
  based 
  upon 
  an 
  examination 
  of 
  a 
  specimen 
  (ex 
  

   coll.

  A. 
  Cockerell) 
  kindly 
  supplied 
  by 
  Mr. 
  E. 
  E. 
  Green, 
  to 
  whom 
  I 
  express 
  my 
  

   thanks, 
  as 
  in 
  the 
  absence 
  of 
  his 
  material 
  I 
  should 
  most 
  certainly 
  have 
  given 
  this 
  

   insect 
  a 
  new 
  specific 
  name. 
  

  

  I 
  have 
  described 
  the 
  morphological 
  characters 
  in 
  some 
  detail 
  as 
  hitherto 
  the 
  true 
  

   characteristics 
  seem 
  to 
  have 
  been 
  almost 
  entirely 
  overlooked.
