Glomeris. 
24.  Glomeris  albicornis  sp.  n. 
Sumatra  :  Singkarah.  Several  specimens. 
Colour.  —  Tergites  shining  black ,  with  pale,  nearly  white  poste- 
rior and  lateral  margins;  in  the  middle  of  the  tergites  the  posterior 
band  is  slightly  thicker  and  in  small  specimens  there  are  obscure  in- 
dications of  a  pale  thin  median  band;  upper  part  of  the  head  fuscous 
with  a  median,  white  band,  antennae  and  region  of  the  labrum 
entirely  white  or  testaceous ,  legs  and  under  surface  of  body  also  white 
or  testaceous. 
Eyes  composed  of  a  longitudinal  series  of  from  7  —  10  ocelli,  with 
an  additional  external  ocellus  and,  in  one  specimen,  two  internal  ocelli. 
Nuchal  plate  (1st  tergite)  marked  with  two  sub-parallel  arched  striae. 
Second  tergite  marked  laterally  with  from  7  —  9  striae,  most  of  which 
cross  the  vertex  ;  the  rest  of  the  tergites  marked  laterally  and  inferiorly 
with  two  or  three  striae;  all  the  tergites  smooth  but  marked  with 
exceedingly  fine  close-set  punctures.  Anal  tergite  with  its  border  very 
lightly  emarginate  in  the  male,  but  not  impressed,  being  convex 
from  above  downwards  and  from  side  to  side. 
The  male  with  the  17th  pair  of  legs  very  small;  18th  pair  larger 
with  coxae  not  coalesced;  intercoxal  lamina  long  and  piriform,  pro- 
jecting as  far  as  the  distal  margin  of  the  first  segment  of  the  copu- 
latory  feet,  with  a  slender  pointed  process  on  each  side;  copulatory 
foot  composed  of  four  segments ,  the  first,  stout  and  cylindrical,  bears 
a  single  slender  pointed  internal  process,  the  second  segment  also 
stout  and  bearing  a  posterior  stout  more  or  less  spatulate  process 
and  an  anterior  short  and  slender  process  ;  third  segment  stout  and  wide 
and  furnished  posteriorly  with  a  short  blunt  process;  fourth  (distal) 
segment  thick  at  the  base,  becoming  gradually  thin  towards  the 
apex,  and  strongly  curved. 
Length  10.5  mm. 
At  first  sight  this  species  appears  to  be  almost  identical  with  Gl. 
carnifex  var.  pallida  from  Mergui l)  ;  but  the  two  differ  in  some  points 
1)  Pocock:  Journ.  Linn.  Soc.  ZooL  XXI,  p.  290,  pi.  24,  fig.  7.  —  The  copulatory 
feet  of  this  species  were  wrongly  described  as  being  composed  of  five  segments.  In 
reality  there  are  but  four  as  in  this  species.  What  I  mistook  for  the  first  segment 
proves  to  be  merely  membranous  and  not  chitinous.
