the  tergite,  apex  terminated  by  three  spines;  sternite  with  converging 
lateral  borders,  rounded  posterior  angles  and  emarginate  posterior 
border;  legs  long  and  slender,  with  cylindrical  segments,  femur  very 
feebly  spined,  1  at  the  apex  internally,  1  in  the  posterior  half 
of  the  internal  surface,  1  in  the  anterior  half  of  the  under-inner 
edge  and  1  in  the  corresponding  spot  on  the  under  outer  edge, 
tarsi  unarmed,  claw  with  two  spurs. 
Legs-,  1st  pair  with  a  spine  on  the  anterior  surface  of  femur,  pa- 
tella, tibia  and  1st  tarsus,  but  no  inferior  spine  on  the  1st  tarsus; 
2nd  and  3rd  pairs  with  an  anterior  tibial  spine  and  two  1st  tarsal 
spines;  4*  to  the  18^  pairs  with  two  1st  tarsal  spines;  19th  ana 
20th  with  only  a  single  1st  tarsal  spine;  all  the  claws  spurred. 
Length  75  mm. 
This  fine  and  interesting  species  resembles  the  preceding  R.  cari- 
nulata  in  having  carinate  and  denticulate  tergites,  but  differs  from  it 
in  having  fewer  antennal  segments,  more  prosternai  teeth,  differently 
spined  pleurae  and  longer  and  more  sparsely  spined  anal  legs. 
Otocryptops. 
16.  Otocryptops  luzonicus  (Kohl.). 
Celebes:  Luwu.  One  specimen. 
This  specimen  is  of  considerable  interest  since  it  partakes  of  the 
characters  of  the  two  varieties  of  this  species  -  namely  celebensis 
and  australis  -  which  Dr.  Haase  established.  The  first  of  these  was 
from  N.  Celebes;  the  second  from  New  Guinea  and  Halmahera.  But 
since  this  specimen  from  Luwu  is  intermediate  between  the  two  va- 
rieties, they  can  scarcely  receive  any  longer  the  rank  that  was  ori- 
ginally assigned  to  them.

Sumatra:  Singkarah,  A  single  mutilated  specimen. 
Colour  olivaceo-fuscous,  head,  antennae  and  anal  segment  pale 
chestnut. 
Head-plate  ovate,  without  sulci,  overlapped  behind  by  the  first 
tergite.  Antennœ  short  composed  of  17  segments.  Maxillary  coxœ 
wider  than  long,  with  its  anterior  border  wide  and  nearly  straight, 
furnished  on  each  side  with  a  single  seta,  maxillary  feet  rather  slen- 
der, furnished  with  three  internal  setae,  claw  long  slender  and  cur-
