of  colouration  and  in  the  form  of  the  copulatory  foot.  Thus  in  Gl. 
pallida  the  testaceous  band  on  the  tergites  is  wider;  the  lateral  por- 
tions of  the  first  tergite  are  exceedingly  widely  testaceous,  the  black 
not  touching  the  striate  portion  as  it  does  in  this  new  species;  the 
antennae,  too,  in  pallida  are  fuscous  and  not  white  as  in  albicornis; 
and  moreover  in  pallida  the  posterior  process  of  the  third  segment 
(figured  and  described  as  the  fourth)  of  the  copulatory  foot  is  longer, 
pointed  and  more  or  less  blade-like,  instead  of  being  short  and  obtuse 
as  in  albicornis. 
25.  Glomeris  infuscatus ,  sp.  n.  Pl.  XIX,  fig.  10  — 10b. 
Sumatra:  Mount  Singalang,  several  specimens. 
Colour.  —  The  upper  surface  a  dark  slate  grey ,  the  extreme  edges  of 
the  tergites  paler  ;  in  the  posterior  half  of  the  body  there  is  a  feebly 
marked  pale  spot  in  the  middle  of  the  hinder  edge  of  the  tergites  ;  ventral 
surface  pale;  legs  lightly  infuscate. 
Eyes  composed  of  seven  ocelli;  six  in  a  longitudinal  series  and  one 
external  to  this  series. 
Nuchal  plate  (1st  tergite)  marked  by  two  conspicuous  arched  grooves 
which  cross  it  from  corner  to  corner. 
Second  dorsal  plate  marked  laterally  with  from  nine  to  twelve  striae , 
most  of  which  cross  the  summit  of  the  plate;  the  rest  of  the  ter- 
gites marked  laterally  and  inferiorly  with  two  or  three  striae. 
All  the  tergites  smooth  but  marked  with  exceedingly  small,  close-set 
punctures. 
Anal  tergite  in  the  female  convex  from  side  to  side ,  nearly  straight 
from  above  downwards;  in  the  male,  with  the  hinder  border  emar- 
ginate  in  the  middle  and  with  a  conspicuous  depression  just  above  the 
emargination. 
In  the  male  the  17th  pair  of  legs  are  exceedingly  short,  the  18th 
are  much  longer  than  the  17th  but  shorter  than  the  19th  or  copulatory 
pair;  the  coxal  lamina  is  long  and  piriform,  projecting  as  far  as  the 
distal  margin  of  the  second  segment  of  the  copulatory  feet,  with  a 
short  and  slender  process  on  each  side;  the  first  segment  of  the 
copulatory  feet  is  long  and  bears  no  process,  the  second  is  produced 
posteriorly  into  a  digitiform  prolongation,  the  apex  of  which  extends 
as  far  as  the  apex  of  a  similar  but  much  smaller  digitiform  prolong- 
ation from  the  third  segment,  which  is  somewhat  compressed;  the
