Attenuated  anteriorly  and  posteriorly. 
Colour:  most  of  head ,  first  tergite,  and  part  of  the  second  and  third,  to- 
gether with  the  pleurae  rufo-castaneous  ;  the  rest  of  the  body  including  the 
anterior  margin  of  the  head  and  first  tergite  green  with  metallic  lustre. 
Head  rounded  laterally,  wider  than  long,  sparsely  and  feebly  punc- 
tured. Antennae  long,  composed  of  twenty-one  segments,  whereof 
the  basal  two  are  bare,  the  rest  pubescent.  Maxillary  coxce  with 
prosternai  plates  well  developed,  short,  wide,  in  contact ,  each  furnished 
with  about  seven  teeth  most  of  which  are  ill-defined;  maxillary  feet 
with  conspicuous,  sub-dentate  basal  process. 
Tergites  bisulcate  from  the  sixth  or  seventh,  marginate  from  the 
tenth  or  eleventh,  with  a  low  nearly  obsolete  median  longitudinal 
ridge  and  wrinkled  sides.  Sternites  obsoletely  impressed,  with  two 
faint  abbreviated  sulci  in  front. 
Anal  somite)  tergite  with  strongly  raised  lateral  margins,  angulate 
posterior  margin,  deeply  impressed  above  and  behind;  pleurae  covered 
with  minute  close-set  pores,  produced  into  an  angular,  short,  blunt 
process,  armed  at  its  apex  with  three  spines,  and  with  one  lateral 
spine  halfway  between  the  apex  and  the  tergite;  sternite  with  rounded 
converging  lateral  margins,  rounded  posterior  angles  and  concave 
posterior  margin;  legs  long  and  slender;  one  femur  armed  with  2 
spines,  one  apical,  one  median,  on  the  upper-inner  edge;  2  on  the 
inner  surface  and  4  on  the  infero-external  edge;  the  other  has  5 
smaller  spines,  arranged  in  two  longitudinal  series,  on  the  inner- 
surface  and  5,  also  smaller,  on  the  infero-external  edge;  tarsus 
unarmed,  claw  spurred. 
The  rest  of  the  legs  have  the  claws  spurred,  and  most  of  them 
have  a  spine  on  the  anterior  surface  of  the  distal  end  of  the  tibia 
and  two  distal  spines  on  the  first  tarsal  segment,  one  anterior  and 
one  inferior;  (preanal  pair  of  legs  absent). 
Length  60  mm. 
The  British  Museum  has  a  specimen  of  this  species  which  was  col- 
lected at  mount  Salak  in  Java  by  Mr.  R.  Ejrkpatrick. 
This  specimen  has  2  spines,  one  apical,  on  the  upper  inner  edge 
and  6  strong^spines  in  two  parallel  rows  of  3  each  on  the  lower 
surface  of  the  anal  leg.
