  impressions 
  extending 
  from 
  mid-eye 
  level 
  to 
  the 
  front 
  margin 
  of 
  

   clypeus, 
  gradually 
  contracted 
  in 
  front, 
  and 
  bounded 
  outwardly 
  by 
  

   a 
  ridge, 
  area 
  between 
  them 
  slightly 
  depressed, 
  clypeal 
  suture 
  well 
  

   marked, 
  front 
  margin 
  of 
  cljrpeus 
  faintly 
  emarginate, 
  a 
  seta 
  on 
  each 
  

   side, 
  labrum' 
  tnmcate, 
  6-setose; 
  a 
  narrow 
  furrow 
  running 
  along 
  

   inner 
  margin 
  of 
  eye, 
  widening 
  behind 
  eye 
  and 
  turning 
  obUquely 
  

   inwards 
  for 
  a 
  short 
  distance, 
  just 
  beyond 
  its 
  termination 
  a 
  large 
  

   shallow 
  pore. 
  (These 
  pores 
  are 
  no 
  doubt 
  setiferous, 
  as 
  in 
  other 
  

   species, 
  but 
  the 
  setae, 
  as 
  in 
  the 
  case 
  of 
  the 
  front 
  supra-orbital 
  pores, 
  

   have 
  vanished). 
  Mandibles 
  small, 
  sharp, 
  eyes 
  moderately 
  prominent, 
  

   front 
  margin 
  close 
  to 
  buccal 
  fissure; 
  antennae 
  reaching 
  base 
  of 
  

   thorax, 
  setose 
  from 
  first 
  third 
  of 
  joint 
  4, 
  2 
  very 
  short, 
  rest 
  about 
  

   equal, 
  but

  a 
  little 
  shorter 
  and

  a 
  little 
  longer 
  than 
  the

  angles 
  adjoining

   and 
  quite 
  inconspicuous, 
  margin 
  finely 
  bordered, 
  forming 
  an 
  obtuse 
  

   angle 
  a 
  little 
  before 
  middle, 
  strongly 
  arcuate 
  in 
  front 
  of 
  this, 
  straight 
  

   behind, 
  but 
  sinuate 
  near 
  hind 
  angle, 
  which 
  is 
  right, 
  a 
  (presumably 
  

   setiferous) 
  pore 
  at 
  side 
  angle, 
  none 
  visible 
  at 
  basal 
  angle; 
  trans- 
  

   verse 
  impressions 
  obsolete, 
  median 
  line 
  deep 
  and 
  wide, 
  almost 
  

   reaching 
  extremities, 
  basal 
  foveae 
  elongate, 
  a 
  ridge 
  running 
  inside 
  

   border 
  from 
  near 
  basal 
  angle 
  to 
  near 
  apex, 
  leaving 
  a 
  more 
  or 
  less 
  

   explanate 
  area 
  between 
  it 
  and 
  margin 
  (coloured 
  red), 
  widest 
  opposite 
  

   side 
  angle 
  ; 
  surface 
  shiny, 
  a 
  Little 
  transverse 
  striation 
  at 
  sides, 
  some 
  

   coarse 
  confluent 
  punctures 
  on 
  base 
  and 
  basal 
  foveae.

  and 
  third 
  

   not

  both 
  adjoining 
  stria 
  2, 
  5 
  with 
  a 
  single 
  puncture 
  

   at 
  a 
  third 
  from
