  a 
  jack-boot, 
  stipes 
  rather 
  narrow 
  ; 
  

   maxillary 
  palpus 
  two-jointed 
  (2:3), 
  the 
  first 
  joint 
  broader 
  and 
  bare, 
  the 
  second 
  slightly 
  

   tapered, 
  with 
  one 
  bristle 
  near 
  base, 
  three 
  more 
  distally 
  and 
  a 
  long 
  terminal 
  one 
  with 
  

   a 
  minute 
  bristle 
  at 
  the 
  side. 
  Mentum 
  rather 
  broad, 
  reticulate 
  like 
  the 
  stipes. 
  

   Labial 
  palpus 
  just 
  exceeding 
  basal 
  joint 
  of 
  maxillary 
  palpus, 
  ending 
  truncately 
  

   with 
  two 
  long 
  bristles 
  and 
  a 
  minute 
  one

  The 
  lingua 
  with 
  six 
  setigerous 
  

   marginal 
  cells. 
  Mandibles 
  somewhat 
  oblong, 
  with 
  an 
  outer 
  (ventral) 
  strong 
  tooth 
  

   separated 
  by 
  a 
  deep 
  incision 
  from 
  an 
  inner 
  one 
  which 
  is 
  somewhat 
  longer. 
  The 
  apical 
  

   inner 
  (upper) 
  edge 
  of 
  the 
  mandible 
  is 
  serrate 
  with 
  three 
  to 
  four 
  denticles. 
  Posteriorly 
  

   the

  Thorax 
  : 
  prothorax 
  coarsely 
  reticulate, 
  save 
  for 
  a 
  rather 
  broad 
  median 
  area 
  where 
  

   the 
  pattern 
  is 
  fine 
  and 
  transversely 
  drawn 
  out. 
  There 
  is 
  a 
  small 
  postero-lateral 
  

   semi-circular 
  excision 
  for 
  the 
  spiracle. 
  On 
  each 
  side 
  of 
  the 
  bare 
  median 
  area 
  

   posteriorly 
  are 
  three 
  strong 
  bristles, 
  with 
  three 
  to 
  four 
  weaker 
  ones 
  in 
  front, 
  besides 
  

   one 
  or 
  two 
  microscopic 
  bristles 
  ; 
  on 
  the 
  anterior 
  edge 
  are 
  two 
  median 
  bristles. 
  

   Mesonotum 
  with 
  generally 
  equal, 
  moderate, 
  clearly 
  raised 
  reticulation, 
  which 
  is 
  just 
  

   a 
  little 
  coarser 
  posteriorly. 
  Parapsidal 
  furrows 
  merely 
  indicated 
  anteriorly. 
  The 
  

   bare 
  axillae 
  penetrate 
  deeply 
  and 
  their 
  pattern 
  is 
  rather 
  drawn 
  out 
  and 
  not 
  raised. 
  

   One 
  bristle 
  opposite 
  the 
  inner 
  anterior 
  angle 
  of 
  the 
  axillae, 
  another 
  in 
  front, 
  between
