  it 
  is 
  sharply 
  serrate 
  on 
  the 
  outer 
  edge, 
  and 
  less 
  distinctly 
  so 
  on 
  its 
  inner 
  

   aspect 
  ; 
  the 
  lateral 
  serrations 
  are 
  the 
  terminal 
  units 
  of 
  parallel 
  rows 
  (about 
  50) 
  

   of 
  teeth, 
  numbering 
  15-20 
  per 
  row. 
  Maxilla 
  laterally 
  compressed 
  and 
  appearing 
  like 
  

   a 
  blade 
  between 
  the 
  saws 
  attached 
  to 
  the 
  mandibles 
  ; 
  stipes 
  in 
  the 
  form 
  of 
  a 
  long, 
  

   narrow 
  strip 
  (6:1), 
  broadest 
  near 
  the 
  apex 
  ; 
  galea 
  with 
  two 
  bristles 
  ; 
  palpus 
  entirely 
  

   absent. 
  Labium 
  like 
  a 
  laterally 
  compressed 
  (5:1) 
  spoon 
  ; 
  palpi 
  not 
  certainly 
  present 
  ; 
  

   in 
  their 
  place 
  and 
  possibly 
  homologous 
  with 
  them 
  are 
  two 
  approximated 
  slightly 
  

   raised 
  clear 
  spots 
  which 
  give 
  rise 
  to 
  a 
  bristle 
  ; 
  two 
  minute 
  distal 
  bristles.

  Thorax. 
  — 
  Noteworthy 
  in 
  this 
  region 
  are 
  the 
  reduction 
  of 
  the 
  pronotum, 
  the 
  develop- 
  

   ment 
  of 
  the 
  prothoracic 
  spiracle, 
  the 
  mesonotum 
  and 
  the 
  propodaeum. 
  Pronotum 
  

   short, 
  angularly 
  emarginate 
  behind, 
  consisting 
  of 
  two 
  triangular 
  sclerites 
  connected 
  

   by 
  a 
  narrow, 
  membranous 
  area. 
  On 
  each 
  triangle 
  there 
  is 
  an 
  irregular 
  row 
  of 
  

   bristles 
  along 
  the 
  inner 
  edge, 
  a 
  few 
  more 
  on 
  the 
  outer, 
  and 
  one 
  or 
  two 
  on 
  the 
  surface 
  

   near 
  the 
  posterior 
  angle. 
  Prothoracic 
  spiracle 
  with 
  a 
  strong, 
  terminal 
  chitinous 
  cap, 
  

   which, 
  along 
  with 
  part 
  of 
  the 
  trachea, 
  projects 
  clear 
  of 
  the 
  side 
  ; 
  this 
  structure 
  and 
  

   the 
  tegula 
  are 
  probably 
  the 
  two 
  thorns 
  or 
  spines 
  with 
  which 
  Dalman 
  says 
  his 
  insect 
  

   is 
  provided 
  on 
  the 
  sides 
  of 
  the 
  thorax. 
  Mesonotum 
  triangular 
  before 
  the 
  suture, 
  

   coming 
  to 
  a 
  point 
  anteriorly 
  in 
  the 
  middle 
  of 
  the 
  prothorax 
  ; 
  no 
  definite 
  parapsidal 
  

   furrows 
  ; 
  4-6 
  short 
  bristles 
  posteriorly, 
  on 
  each 
  side 
  of 
  an 
  incomplete 
  median 
  line.
