  covered 
  with 
  white 
  hair 
  ; 
  the 
  trochanters, 
  apex 
  of 
  femora, 
  

   tibiae, 
  and 
  tarsi 
  rufo-testaceous. 
  Petiole 
  as 
  long 
  as 
  the 
  

   hinder 
  coxae 
  ; 
  coarsely 
  shagreened, 
  the 
  sides 
  distinctly 
  

   margined 
  ; 
  beneath, 
  it 
  is 
  prolonged 
  to 
  the 
  apex 
  of 
  the 
  second 
  

   segment 
  ; 
  the 
  base 
  of 
  the 
  third 
  segment 
  being 
  obliquely 
  

   truncated 
  beneath, 
  it 
  forms, 
  with 
  the 
  apex 
  of 
  the 
  petiole, 
  a 
  

   wide, 
  triangular 
  incision. 
  The 
  rest 
  of 
  the 
  abdomen 
  smooth 
  

   and 
  shining 
  ; 
  the 
  apex 
  without 
  a 
  pygidial 
  area. 
  

  

  In 
  some 
  respects 
  this 
  species 
  is 
  intermediate 
  between 
  

   Pempliredon 
  and 
  Passaloecus, 
  its 
  petiole 
  being 
  longer 
  

   than 
  it 
  is 
  in 
  the 
  latter, 
  but 
  much 
  shorter 
  than 
  in 
  

   the 
  former, 
  from 
  which 
  it 
  further 
  differs 
  in 
  the 
  hinder 
  

   tibiae 
  not 
  being 
  spined 
  ; 
  in 
  the 
  head 
  not 
  being 
  covered 
  

   with 
  long 
  hair 
  ; 
  in 
  the 
  margined 
  eyes, 
  in 
  the 
  vertex 
  

   and 
  hollowed 
  front 
  bearing 
  keels 
  ; 
  and 
  in 
  the 
  median 
  

   segment 
  having 
  keels 
  which 
  form 
  large 
  distinct 
  areae, 
  

   the 
  lower 
  part 
  of 
  the 
  segment, 
  too, 
  being 
  largely 
  and 
  

   deeply 
  hollowed. 
  The 
  labrum 
  is 
  not 
  emarginate 
  at 
  the 
  

   apex, 
  so 
  far 
  as 
  I 
  can 
  make 
  out 
  from 
  the 
  dense 
  silvery 
  

   pubescence 
  which 
  covers 
  the 
  mouth 
  ; 
  the 
  mandibles 
  are 
  

   large, 
  not 
  furrowed 
  ; 
  oblique 
  at 
  the 
  apex, 
  where 
  there 
  is 
  

   one 
  large, 
  acute 
  tooth, 
  and 
  a 
  much 
  smaller 
  and 
  blunter 
  one, 
  

   next 
  to 
  it. 
  The 
  eyes 
  reach 
  to 
  the 
  base 
  of 
  the 
  mandibles 
  

   and 
  are 
  parallel 
  ; 
  the 
  antennae 
  are 
  situated 
  quite 
  close 
  to 
  

   the 
  base 
  of 
  the 
  clypeus, 
  but 
  not 
  touching 
  it 
  ; 
  the 
  transverse 
  

   basal 
  nervure 
  is 
  interstitial 
  ; 
  on 
  the 
  mesopleurae 
  there 
  is 
  

   one 
  distinct, 
  moderately 
  wide 
  and 
  deep, 
  complete, 
  longi- 
  

   tudinal 
  furrow. 
  The 
  second 
  cubital 
  cellule 
  is 
  much 
  

   narrower 
  than 
  it 
  is 
  in 
  either 
  PempJiredron 
  or 
  Passaloecus 
  

   proper, 
  and 
  is 
  much 
  narrowed 
  on 
  the 
  lower 
  side 
  ; 
  the 
  

   stigma 
  is 
  large 
  ; 
  the 
  radial 
  cellule 
  elongate, 
  lanceolate 
  ; 
  

   in 
  the 
  female, 
  there 
  is 
  no 
  pygidial 
  area. 
  The 
  tubercules 
  

   do 
  not 
  reach 
  to 
  the 
  tegulae. 
  

  

  This 
  species, 
  having 
  only 
  one 
  longitudinal 
  furrow 
  on 
  the 
  

   mesopleurae, 
  is 
  a 
  Passaloecus 
  as 
  limited
