  segmented 
  in 
  the 
  proportion 
  of 
  4:3:3 
  ; 
  the 
  apical 
  joint 
  with 
  a 
  spur. 
  In 
  no 
  region 
  

   is 
  the 
  antenna 
  really 
  black, 
  but 
  the 
  funicle 
  and 
  club 
  are 
  dusky. 
  After 
  the 
  ring 
  joints 
  

   all 
  the 
  joints 
  bear 
  both 
  hairs 
  and 
  sensory 
  channels 
  surmounted 
  by 
  clear, 
  triangular, 
  

   chitinous 
  flanges. 
  

  

  Thorax 
  black 
  with 
  bluish 
  and 
  even 
  slightly 
  greenish 
  reflections, 
  except 
  on 
  the 
  

   pronotum, 
  where 
  there 
  is 
  a 
  purplish 
  tinge. 
  Pronotum 
  narrow 
  antero-posteriorly 
  

   and 
  descending 
  roundly 
  towards 
  the 
  occiput 
  and 
  neck, 
  neither 
  elongated 
  anteriorly 
  

   nor 
  sharply 
  ridged 
  transversely. 
  The 
  whole 
  surface 
  is 
  reticulate, 
  delicately 
  so 
  

   from 
  the 
  neck 
  to 
  the 
  posterior 
  edge, 
  the 
  pattern 
  becoming 
  coarser 
  towards 
  the 
  

   sides 
  and 
  reaching 
  its 
  maximum 
  on 
  the 
  pleural 
  flap 
  enveloping 
  the 
  pre-episternite. 
  

   One 
  strong 
  short 
  bristle 
  above 
  the 
  spiracle 
  on 
  each 
  side, 
  and 
  between 
  these 
  a 
  

   transverse 
  row 
  of 
  similar 
  bristles 
  (twelve 
  in 
  all), 
  the 
  median 
  pair 
  stronger 
  than 
  

   the 
  others 
  ; 
  the 
  general 
  surface 
  of 
  the 
  pronotum 
  in 
  front 
  of 
  this 
  row 
  with 
  numerous 
  

   minute 
  hairs, 
  60 
  to 
  70 
  in 
  all. 
  Mesonotum 
  (fig. 
  16) 
  with 
  the 
  parapsidal 
  furrows 
  complete, 
  

   straight, 
  wide, 
  deep 
  ; 
  two 
  widely 
  separated 
  parallel 
  lateral 
  furrows 
  on 
  the 
  scutellum. 
  

   No 
  furrow 
  on 
  the 
  mid 
  lobe 
  of 
  the 
  mesonotum, 
  but 
  the 
  mid 
  line 
  in 
  a 
  cleared 
  specimen 
  

   indefinitely 
  paler. 
  Axillae 
  sharply 
  and 
  extensively 
  produced 
  into 
  the 
  parapsides 
  

   or 
  lateral 
  lobes. 
  Entire 
  surface 
  evenly 
  reticulate, 
  the 
  pattern 
  being 
  coarser 
  only 
  

   at 
  the 
  outer 
  edge 
  of 
  the 
  mid 
  lobe. 
  The 
  latter 
  bare 
  on 
  the 
  anterior 
  quarter, 
  with 
  

   over 
  30 
  short 
  bristles 
  behind 
  and 
  one 
  strong 
  bristle 
  before 
  the 
  postero-lateral 
  angle. 
  

   Lateral 
  lobes 
  with 
  one 
  strong 
  bristle 
  at 
  the 
  postero-lateral 
  angle 
  before 
  the 
  tegula, 
  

   and 
  some 
  15 
  others 
  on 
  the 
  surface. 
  Axillae 
  bare. 
  Scutellum 
  with 
  the 
  lateral 
  lines 
  

   well-marked, 
  mid 
  lobe 
  with 
  two 
  parallel 
  rows 
  (3, 
  3) 
  of 
  clear 
  pustules, 
  the 
  first 
  and 
  

   third 
  setigerous 
  ; 
  outer 
  lobes 
  bare. 
  Metanotum 
  distinctly 
  developed 
  in 
  three 
  

   surfaces, 
  viz. 
  : 
  — 
  two 
  smooth 
  and 
  depressed 
  at 
  the 
  sides, 
  with 
  a 
  median 
  broadly 
  

   pentagonal 
  reticulate 
  area, 
  separated 
  from 
  the 
  sides 
  by 
  ridges. 
  Propodaeum 
  well 
  

   developed, 
  oblong, 
  with 
  straight 
  posterior 
  edge 
  and 
  distinct 
  lateral 
  angles, 
  which 
  

   do 
  not 
  project 
  beyond 
  the 
  line 
  connecting 
  them 
  and 
  passing 
  through 
  the 
  insertion 
  

   of 
  the 
  petiole. 
  Apparently 
  flat 
  from 
  above, 
  but 
  really 
  declivous 
  on 
  the 
  posterior 
  

   quarter 
  and 
  towards 
  the 
  sides 
  from 
  the 
  sharply 
  defined 
  central 
  keel. 
  There 
  is 
  no 
  

   lateral 
  keel 
  or 
  ridge 
  except 
  near 
  the 
  extreme 
  side, 
  where 
  there 
  is 
  an 
  abrupt 
  descent 
  

   of 
  the 
  pleura 
  to 
  the 
  insertion 
  of 
  the 
  coxa. 
  The 
  spiracle 
  lies 
  at 
  the 
  anterior 
  angle 
  of 
  

   the 
  dorsum. 
  The 
  entire 
  upper 
  surface 
  of 
  the 
  propodaeum 
  is 
  bare 
  and 
  reticulate 
  ; 
  

   on 
  the 
  pleurae, 
  above 
  the 
  metacoxae, 
  are 
  three 
  short 
  bristles. 
  The 
  most 
  distinct 
  

   character 
  of 
  the 
  propodaeum 
  as 
  a 
  whole 
  is 
  that 
  the 
  anterior 
  and 
  posterior 
  and 
  the 
  

   lateral 
  edges 
  respectively 
  are 
  parallel, 
  save 
  where 
  the 
  posterior 
  edge 
  is 
  excavated 
  

   for 
  the 
  petiole. 
  The 
  sternum 
  of 
  the 
  thorax 
  reticulate 
  ; 
  the 
  mesosternum 
  somewhat 
  

   quadrate 
  with 
  a 
  central 
  ridge 
  ; 
  bare 
  ; 
  mesopleurae 
  furrowed 
  ; 
  mesoprepectus 
  large, 
  

   triangular, 
  reticulate 
  ; 
  sternite 
  divided 
  by 
  a 
  ridge 
  into 
  an 
  upper 
  smooth 
  and 
  a 
  

   ventral 
  reticulate 
  portion 
  ; 
  epimeron 
  bare. 
  

  

  Wings 
  : 
  fore 
  wings 
  long 
  and 
  narrow 
  (20 
  : 
  7), 
  shortly 
  ciliated 
  at 
  the 
  edges, 
  widest 
  

   at 
  a 
  point 
  well 
  beyond 
  the 
  radius. 
  Submarginal 
  a 
  little 
  shorter 
  than 
  the 
  marginal 
  

   (5 
  : 
  6), 
  with 
  only 
  a 
  trace 
  of 
  the 
  postmarginal 
  ; 
  radius 
  moderate, 
  with 
  four 
  cells 
  (fig. 
  15, 
  e) 
  ; 
  

   both 
  marginal 
  and 
  submarginal 
  veins 
  broad 
  and 
  the 
  former 
  only 
  narrowly 
  inter- 
  

   rupted 
  ; 
  the 
  marginal 
  vein 
  bears 
  seven 
  to 
  eight 
  stout 
  bristles. 
  The 
  whole 
  wing 
  has 
  a 
  

   faint 
  transparent 
  brown 
  tint. 
  Length,
