Colour-,  head  brown,  antennas  infuscate;  somites  above  pitch  black  or 
deep  brown,  contrasting  strongly  with  the  flavous  tint  of  the  keels  and 
caudal  process;  lateral  surface  black,  or  deep  brown;  sternal  areas  flavous,

First  tergite  convex,  wider  than  the  head,  distinctly  keeled,  the 
keel  depressed,  its  posterior  border  directed  forwards,  its  hinder  angle 
sharp,  its  anterior  border  evenly  convex  from  the  posterior  angle.  The 
second  tergite  as  wide  as  the  first,  its  keel  well- developed  and  just 
below  the  level  of  the  keel  of  the  first  and  of  the  third,  its  anterior 
angle  not  produced,  its  posterior  angle  strongly  produced.  Keels  of 
the  third  and  fourth  well  developed,  concave  behind,  convex  in  front, 
with  pointed  posterior  angle.  The  keels  of  the  rest  horizontal,  rising 
above  the  middle  of  the  side,  well  developed,  the  lateral  border  parallel 
to  the  long  axis  of  the  body,  the  position  of  the  pore  clearly  defined, 
the  anterior  angle  rounded,  the  posterior  angle  acute  and  produced 
beyond  the  level  of  the  posterior  border  of  the  tergite,  the  lateral 
margin  thickened.  The  dorsal  surface  shining,  almost  smooth,  lightly 
longtudinally  striolate;  the  transverse  sulcus  well-marked,  slightly 
sinuate  in  the  middle,  beginning  on  the  fourth.  Lateral  surfaces  finely 
granular,  smoother  towards  the  hinder  end  of  the  body.  Inferior  crest 
or  keel  well  developed  on  the  first  four  somites ,  represented  from  the 
fifth  about  the  twelfth  by  a  posterior  tubercle  which  decreases  in  size 
towards  the  posterior  end  of  the  body.  Caudal  process  with  its  sides 
slightly  converging  posteriorly,  the  apex  truncate  and  bifid,  its  upper 
surface  raised  above  the  level  of  the  rest  of  the  tergite.  Anal  sternite 
normally  bituberculate.  Sterna  and  legs  normal. 
Length  up  to  about  38  mm.;  width  of  10^  segment  5.4.

with  the  keels  a  little  higher.  The  sternal  process  of  the  5*h  segment 
consisting  of  two  distinct  tubercles.  The  copulatory  feet  like  those  of 
coar datum,  slender  curved,  terminating  distally  in  two  processes  the
