  $. 
  — 
  Head 
  broader 
  than 
  thorax 
  (5 
  : 
  4), 
  much 
  broader 
  than 
  long 
  (5 
  : 
  2), 
  the 
  length 
  

   being 
  measured 
  across 
  the 
  vertex 
  ; 
  occiput 
  very 
  concave, 
  the 
  edge 
  sharp. 
  Eyes 
  large, 
  

   densely 
  clothed 
  with 
  whitish 
  pubescence 
  ; 
  malar 
  space 
  distinct, 
  triangular. 
  Frons 
  

   slightly 
  prominent 
  at 
  the 
  base 
  line 
  of 
  the 
  eyes, 
  just 
  above 
  which 
  the 
  antennae 
  are 
  set 
  ; 
  

   vertex 
  coarsely 
  reticulate, 
  seen 
  from 
  above 
  shining 
  green. 
  Posterior 
  ocelli 
  about 
  

   twice 
  as 
  far 
  from 
  one 
  another 
  as 
  from 
  the 
  ocular 
  edge. 
  Behind 
  the 
  posterior 
  ocelli 
  

   the 
  vertex 
  is 
  a 
  little 
  excavated 
  and 
  smoothed 
  towards 
  the 
  postero-lateral 
  angle 
  of 
  

   the 
  occiput, 
  but 
  the 
  reticulation 
  reappears 
  just 
  before 
  the 
  occiput 
  is 
  reached. 
  Occiput 
  

   sharply 
  defined, 
  surface 
  down 
  to 
  the 
  neck 
  (facing 
  the 
  prothorax) 
  dull, 
  reticulate, 
  dark 
  

   purple. 
  Frons 
  coarsely 
  reticulate 
  to 
  below 
  the 
  anterior 
  ocellus 
  (which 
  divides 
  a 
  

   line 
  drawn 
  from 
  the 
  apex 
  of 
  either 
  scape 
  to 
  the 
  opposite 
  posterior 
  ocellus), 
  and 
  con- 
  

   colorous 
  with 
  the 
  vertex 
  ; 
  its 
  surface 
  up 
  to 
  this 
  point 
  flat 
  or 
  slightly 
  convex, 
  but 
  

   below 
  the 
  anterior 
  ocellus 
  the 
  face 
  is 
  hollowed, 
  consisting 
  of 
  two 
  inclined 
  finely 
  

   reticulate 
  plates, 
  which 
  unite 
  rather 
  indistinctly 
  in 
  the 
  middle, 
  but 
  with 
  clear 
  sutures 
  

   above 
  from 
  the 
  anterior 
  ocellus 
  to 
  the 
  upper 
  margin 
  of 
  the 
  eye 
  ; 
  the 
  face 
  here 
  has 
  

   aeneous 
  reflections, 
  but 
  from 
  in 
  front 
  is 
  dark 
  green 
  ; 
  the 
  lower 
  mid 
  line 
  of 
  the 
  frons 
  

   and 
  the 
  clypeus, 
  which 
  is 
  gently 
  concave 
  on 
  the 
  oral 
  edge, 
  is 
  smooth. 
  Above 
  the 
  

   middle 
  of 
  the 
  frons 
  the 
  orbits 
  are 
  subparallel, 
  but 
  they 
  diverge 
  both 
  towards 
  the 
  

   occiput 
  and 
  the 
  genae. 
  All 
  the 
  frons 
  wide, 
  the 
  shortest 
  distance 
  between 
  the 
  eyes 
  

   being 
  J-§ 
  greater 
  than 
  the 
  width 
  of 
  the 
  eye 
  seen 
  from 
  the 
  same 
  aspect. 
  Genae 
  duller, 
  

   with 
  short 
  pubescence, 
  at 
  most 
  showing 
  a 
  faint, 
  purplish 
  reflection. 
  On 
  the 
  occipital 
  

   edge 
  4 
  bristles, 
  viz., 
  a 
  median 
  pair 
  with 
  one 
  on 
  each 
  side 
  aligned 
  after 
  an 
  interval 
  

   with 
  a 
  row 
  of 
  five 
  bristles, 
  which 
  fringe 
  the 
  orbit, 
  the 
  last 
  of 
  this 
  row 
  standing 
  at 
  

   the 
  level 
  of 
  the 
  apex 
  of 
  the 
  scape 
  ; 
  below 
  this 
  on 
  each 
  side 
  a 
  row 
  of 
  5-6 
  minute 
  bristles 
  ; 
  

   across 
  the 
  clypeus, 
  above 
  the 
  mouth 
  edge, 
  6 
  bristles 
  (3, 
  3) 
  and 
  a 
  pair 
  below 
  the 
  scrobes 
  ; 
  

   a 
  single 
  hair 
  behind 
  the 
  anterior 
  ocellus 
  and 
  one 
  inside 
  each 
  of 
  the 
  posterior 
  ocelli 
  ; 
  

   between 
  the 
  ocellar 
  triangle 
  and 
  the 
  apices 
  of 
  the 
  scapes 
  two 
  pairs 
  of 
  lateral 
  medianly 
  

   convergent 
  bristles. 
  

  

  Antennae 
  eight- 
  jointed 
  (fig. 
  2, 
  b) 
  : 
  scape, 
  pedicel, 
  one 
  ring 
  joint, 
  three 
  funicular 
  and 
  

   two 
  in 
  the 
  club 
  — 
  the 
  last 
  with 
  a 
  terminal 
  spur. 
  Scape 
  slender, 
  five 
  times 
  as 
  long 
  as 
  

   broad, 
  on 
  ventral 
  edge 
  6-7 
  hairs, 
  dorsally 
  about 
  three. 
  Pedicel 
  about 
  twice 
  as 
  long 
  as 
  

   broad, 
  shorter 
  than 
  first 
  funicular 
  joint. 
  Ring 
  joint 
  very 
  small 
  ; 
  under 
  a 
  high 
  power, 
  

   apparently 
  consisting 
  of 
  at 
  least 
  two 
  laminae, 
  closely 
  appressed. 
  The 
  funicular 
  joints, 
  

   especially 
  the 
  second 
  and 
  third, 
  pedunculate 
  anteriorly, 
  first 
  longest, 
  second 
  and 
  

   third 
  decreasing 
  slightly 
  ; 
  first 
  joint 
  of 
  club 
  much 
  bigger 
  than 
  the 
  second. 
  Joints 
  

   4-8 
  show 
  three 
  kinds 
  of 
  structure 
  : 
  (a) 
  long 
  scattered 
  hairs, 
  (b) 
  short 
  mushroom-like
