lower  of  which  constitutes  a  sheath  for  the  upper  which  is  flagelliform. 
A  single  9  example  of  what  is  either  the  same  or  a  closely  allied 
species  was  bronght  from  Macassar.  There  appear  to  be  slight  differences 
in  the  form  of  the  keels  between  it  the  Javan  form ,  but  without 
knowing  the  male,  I  refrain  from  establishing  another  species  for  the 
reception  of  this  specimen. 
65.  Strongylosoma  conspicuurn,  sp.  n.  Pl.  XXII,  fig.  9. 
Java:  Buitenzorg.  Two  cf  examples. 
Closely  allied  to  the  preceding;  but  differing  as  follows. 
The  body  is  more  slender  (length  33  mm.,  width  3.7);  the  keels 
are  a  little  larger  and  more  yellow  i.  e.  the  black  of  the  dorsal  surface 
does  not  spread  on  to  them  at  the  base  at  it  does  in  weberi.  The 
caudal  process  is  larger  and  more  yellow,  with  its  sides  parallel  and 
not  converging,  approaching  what  is  seen  in  Leptodesmus. 
66.  Strongylosoma  atro-roseum,  sp.  n. 
Java:  Buitenzorg.  A  single  9  example. 
Colour;  head  brown,  paler  below;  antennas  infuscate;  dorsal  surface 
brown,  keels  and  caudal  process  of  a  yellowish-pink  tint  ;  lateral  surface 
pale  brown  above,  fading  into  yellow  below;  legs  and  sterna  flavous. 
Head  smooth  and  sulcate  above;  antennœ  moderately  long. 
First  tergite  convex,  anterior  border  convex  from  side  to  side,  keeled, 
anterior  angle  of  keel  very  obtuse,  posterior  angle  nearly  rectangular, 
its  posterior  border  directed  slightly  backwards.  The  keel  of  the  second 
considerably  below  that  of  the  first  and  of  the  third ,  anteriorly  and 
posteriorly  produced.  Keels  of  third  and  fourth  well  developed,  with 
rounded  anterior  and  acute  posterior  angles.  Keels  of  the  rest  above 
the  middle  of  the  side,  well  developed,  with  thickened  margins, 
rounded  anterior  angle,  and  acute  posterior  angle;  the  posterior  angle 
of  the  fifth  about  on  a  level  with  the  posterior  border  of  the  tergite, 
those  of  the  rest  becoming  progressively  more  and  more  produced 
from  before  backwards.  The  pores  situated  on  the  lower  edge  of  the 
lateral  surface  of  keels.  The  dorsal  surface  smooth,  only  very  slightly 
polished.  The  transverse  sulcus  nearly  straight,  rather  shallow,  not 
punctured.  The  anterior  groove  not  sculptured.  Lateral  surfaces  nearly 
smooth  and  shining,  only  at  the  anterior  end  of  the  body  very  finely 
granular  below.  Inferior  crest  only  present  on  the  2nd,  3nd  and  Caudal
