  on 
  each 
  side 
  at 
  the 
  orbits 
  and 
  about 
  16, 
  short, 
  stout 
  and 
  spinose, 
  on 
  the 
  ocellar 
  

   triangle 
  ; 
  on 
  each 
  frontal 
  plate 
  from 
  the 
  upper 
  suture 
  to 
  the 
  scrobes 
  are 
  about 
  a 
  

   dozen 
  bristles, 
  placed 
  mainly 
  near 
  the 
  orbits. 
  Scrobes 
  rather 
  large, 
  oval, 
  just 
  above 
  

   the 
  base 
  line 
  of 
  the 
  eyes 
  ; 
  a 
  distinct 
  keel 
  from 
  the 
  clypeal 
  corner 
  to 
  the 
  lower 
  angle 
  

   of 
  the 
  eye, 
  with 
  nine 
  to 
  ten 
  short 
  bristles 
  inside, 
  on 
  the 
  frontal 
  aspect. 
  

  

  Antennae 
  11-jointed 
  (fig. 
  17, 
  a) 
  : 
  scape, 
  pedicel, 
  three 
  ring 
  joints, 
  funicle 
  of 
  three, 
  club 
  

   of 
  three. 
  Length, 
  1 
  mm. 
  ; 
  long, 
  cylindrical 
  and 
  not 
  expanded 
  in 
  the 
  club. 
  The 
  scape 
  

   is 
  flavescent, 
  and 
  the 
  other 
  joints 
  (except 
  the 
  ring 
  joints) 
  brownish 
  and 
  infuscated 
  ; 
  

   the 
  pedicel 
  a 
  little 
  flavescent 
  below. 
  Scape 
  three-and-a-half 
  times 
  as 
  long 
  as 
  broad, 
  

   with 
  one 
  strong 
  subapical 
  ventral 
  bristle, 
  and 
  two 
  to 
  three 
  behind 
  on 
  the 
  same 
  line. 
  

   Pedicel 
  not 
  half 
  the 
  length 
  of 
  the 
  scape, 
  longer 
  then 
  broad 
  (8:5). 
  Three 
  ring 
  joints, 
  

   the 
  basal 
  one 
  with 
  a 
  broad 
  articulation, 
  the 
  others 
  more 
  leaf-like, 
  but 
  apparently 
  

   distinct. 
  Funicle 
  joints 
  cylindrical 
  and 
  elongate, 
  about 
  twice 
  as 
  long 
  as 
  broad, 
  

   and 
  subequal 
  ; 
  the 
  middle 
  one 
  a 
  trifle 
  longer 
  than 
  the 
  first 
  or 
  the 
  third, 
  each 
  

   bearing 
  about 
  12 
  sensoria 
  with 
  strong 
  processes. 
  Club 
  joints 
  in 
  the 
  proportions 
  

   9:8:6; 
  the 
  third 
  joint 
  tapered 
  into 
  a 
  stout 
  spur, 
  on 
  which 
  stands 
  a 
  minute 
  bristle 
  ; 
  

   the 
  sensoria 
  well 
  developed.

  melicJilorus,

  ;

  antenna 
  ; 
  

   fc, 
  mandible. 
  

  

  Mouth-parts 
  : 
  the 
  cardo 
  boot-shaped, 
  the 
  heel 
  rounded 
  off, 
  and 
  the 
  stipes 
  large. 
  

   The 
  maxillary 
  palpus 
  four 
  to 
  five 
  times 
  as 
  long 
  as 
  the 
  labial, 
  with 
  one 
  post-median 
  

   outer 
  hair, 
  two 
  (a 
  shorter 
  and 
  a 
  longer) 
  subapical, 
  and 
  exactly 
  at 
  the 
  apex, 
  a 
  thick 
  

   truncated 
  hyaline 
  bristle. 
  Galea 
  with 
  four 
  or 
  five 
  of 
  the 
  stronger 
  bristles 
  rising 
  

   from 
  cells. 
  Mentum 
  with 
  a 
  single, 
  rather 
  long 
  bristle 
  well 
  behind 
  the 
  base 
  of 
  the 
  

   palpi. 
  Lingua 
  with 
  four 
  setigerous 
  marginal 
  cells. 
  Mandibles 
  (fig. 
  17, 
  b) 
  with 
  three 
  teeth, 
  

   the 
  outer 
  (ventral) 
  pair 
  rather 
  deeply 
  separated 
  and 
  of 
  equal 
  length, 
  the 
  innermost 
  

   marked 
  off 
  by 
  a 
  shallow 
  concavity 
  and 
  with 
  rounded 
  apex 
  ; 
  behind 
  the 
  third 
  tooth 
  

   the 
  mandible 
  swells 
  out, 
  but 
  contracts 
  at 
  the 
  middle 
  of 
  the 
  inner 
  edge, 
  being 
  again 
  

   slightly 
  swollen 
  on 
  the 
  same 
  edge 
  near 
  the 
  base. 
  

  

  Thorax 
  longer 
  than 
  broad 
  (3:2). 
  Pronotum 
  entirely 
  brownish 
  black, 
  with 
  a 
  posterior 
  

   row 
  of 
  eight 
  to 
  ten 
  bristles, 
  and 
  many 
  in 
  front. 
  Mesonotum 
  yellowish, 
  with 
  a 
  distinct 
  

   brown 
  blotch 
  extending 
  from 
  the 
  base 
  four-sevenths 
  towards 
  the 
  apex 
  ; 
  apically 
  

   the 
  blotch 
  is 
  a 
  little 
  incised 
  medianly, 
  and 
  at 
  the 
  sides 
  near 
  the 
  parapsidal 
  furrows 
  

   there 
  is 
  a 
  narrow, 
  indefinitely 
  paler 
  margin 
  ; 
  along 
  this 
  margin 
  are 
  placed 
  six 
  hairs, 
  

   and 
  a 
  stronger 
  bristle 
  near 
  the 
  apical 
  corner. 
  The 
  median 
  furrow 
  is 
  broad, 
  and 
  

   completely 
  interrupts 
  the 
  moderately 
  coarse, 
  even 
  reticulation 
  of 
  the 
  lobe.
