This  species  is  very  nearly  allied  to  0.  multidens  of  Haase  from 
Celebes,  but  the  colour  is  different,  the  antennae  are  longer,  the 
denticles  of  the  coxal  plates  and  of  the  basal  tooth  are  much  more 
blunt  and  very  ill-defined;  moreover  Dr.  Haase  makes  no  mention  in 
his  description  of  any  deep  impression  on  the  anal  tergite.  It  also 
appears  to  resemble  0.  longicorne  of  Tömösvary  from  Borneo,  but  in 
this  species  the  antennae  are  much  longer,  being  composed  of  25  or 
more  segments.

Colour:  upper  surface  bluish-green;  under  surface  much  paler;  anal 
legs  bluish-green. 
Head-plate  heart-shaped,  slightly  wider  than  long;  antennae  long, 
extending  to  the  hinder  edge  of  the  sixth  tergite  ;  composed  of  seventeen 
cylindrical  segments  whereof  the  basal  three  are  bare  and  the  rest 
clothed  with  testaceous  pubescence. 
Maxillary  coxal  plates  wide,  much  wider  than  long,  in  contact  in 
the  middle,  anterior  border  of  each  convex  and  furnished  with  six  ill- 
defined  teeth;  basal  tooth  of  the  maxillipedes  well- developed  and  sub- 
dentate. 
Tergites  from  the  third  sulcate,  from  the  sixth  or  seventh  margi- 
nate,  except  the  first  five  or  six  laterally  rugulose;  at  the  posterior 
end  of  the  body  much  more  strongly  rugulose,  with  a  low  median 
longitudinal  carina,  sub-carinate  laterally  and  furnished  with  many 
spinuliform,  sub-serially  arranged  denticles. 
Sternites,  wholly  smooth,  with  two  very  short  anterior  sulci. 
Anal  somite;  tergite  with  an  anterior  low,  median  ridge ,  wider 
behind  than  in  front ,  with  convex  slightly  produced  posterior  margin  ; 
pleurae  finely  and  closely  porous,  somewhat  strongly  produced,  with 
a  single  postero-lateral  spine,  about  half  way  between  the  apex  and
