  Head 
  from 
  in 
  front 
  wider 
  (12 
  : 
  11) 
  than 
  deep 
  (fig. 
  4, 
  b), 
  clypeal 
  edge 
  straight. 
  

   Eyes 
  with 
  very 
  short 
  scattered 
  pubescence, 
  in 
  profile 
  occupying 
  two-thirds 
  of 
  the 
  

   depth 
  of 
  the 
  head 
  and 
  so 
  large 
  that 
  at 
  the 
  level 
  of 
  the 
  anterior 
  ocellus 
  they 
  are 
  separated 
  

   by 
  only 
  one-sixth 
  and 
  at 
  the 
  base 
  line 
  by 
  about 
  two-thirds 
  of 
  the 
  width. 
  Toruli 
  

   (12 
  : 
  7) 
  set 
  low 
  down, 
  not 
  half 
  their 
  length 
  from 
  the 
  clypeal 
  edge, 
  and 
  separated 
  by 
  

   one 
  and 
  a 
  half 
  lengths 
  from 
  one 
  another. 
  The 
  frons 
  is 
  practically 
  smooth 
  and 
  bare, 
  

   save 
  for 
  the 
  usual 
  row 
  of 
  orbital 
  bristles, 
  but 
  the 
  inflexed 
  face 
  is 
  finely 
  striate-reticulate, 
  

   becoming 
  more 
  normally 
  reticulate 
  towards 
  the 
  genal 
  keel. 
  About 
  20 
  bristles 
  between 
  

   the 
  toruli. 
  The 
  narrow 
  vertex 
  (fig. 
  4, 
  a) 
  is 
  smooth, 
  with 
  the 
  ocelli 
  in 
  an 
  isosceles 
  triangle.

   joint 
  minute. 
  Funicle

  three) 
  equal, 
  and 
  if 
  the

  is 
  taken 
  as 
  15 
  the 
  

   breadths 
  are

  24, 
  28. 
  The 
  second 
  funicular 
  joint 
  bears 
  six 
  sensoria.

  of 
  which 
  is 
  densely 
  set 
  with 
  fine 
  bristles.
