5th  subequal  in  length,  the  6^  longer,  the  7th  conical  and  nearly  as 
long  as  the  2nd. 
First  tergite  about  twice  as  wide  as  the  head,  but  much  narrower 
than  the  second,  with  its  keels  lightly  depressed,  their  posterior  bor- 
ders directed  obliquely  forwards,  and  their  anterior  borders  directed 
slightly  backwards  to  meet  the  posterior  border  in  the  lateral  angle 
which  is  very  pointed,  the  anterior  border  weakly  dentate ,  the  posterior 
border  furnished  with  a  row  of  about  7  elongate  tubercular  teeth; 
the  whole  of  the  upper  surface,  including  the  keels,  tubercular.  The 
keels  of  the  rest  of  the  somites  very  similar  in  form,  depressed,  about 
twice  as  wide  as  long,  narrowed  distally,  mostly  at  right  angles  to 
the  long  axis  of  the  body ,  although  directed  backwards  towards  the 
hinder  end  of  the  body;  the  anterior  border  of  each,  straight,  with 
a  small  basal  shoulder  and  unarmed;  the  anterior  angle  very  convex 
and  armed  with  distinct  sharp  teeth,  which  become  smaller  upon 
the  lateral  border;  the  posterior  angle  tooth-like  and  directed  back- 
wards ,  directed  more  and  more  strongly  backwards  towards  the  hinder 
end  of  the  body  ;  the  posterior  border  furnished  with  a  row  of  about 
7  large  elongate,  rounded,  equi-distant  teeth,  nearly  straight  at  the 
anterior  end  of  the  body  but  coming  gradually  lightly  concave  towards 
the  hinder  end.  The  dorsal  surface  of  each  somite  more  or  less  hairy 
and  furnished  with  five  irregular  transverse  rows  of  distinct  tubercles  ; 
on  the  keels  the  tubercles  become  reduced  in  size  and  number,  there 
being  about  two  rows;  lower  surface  of  the  keels  smooth.  The  lateral 
surface  of  the  somites  thickly  hairy.  Caudal  process  triangular,  poin- 
ted, tubercular  throughout,  projecting  posteriorly  beyond  the  apex  of 
the  keels  of  the  19th.  Anal  sternite  bitubercular.  Sternal  areas  very 
narrow,  deeply  grooved  longitudinally. 
Length  16  mm.;  width  4.8 
c?.  Legs  of  the  6th  and  7th  somites  widely  separated ,  to  make  room 
for  the  copulatory  feet  which  are  partially  internal

Java:  Buitenzorg.  Several  specimens. 
1)  Since  this  species  will  doubtless  prove  to  be  generically  distinct  from  the  following, 
I  propose  the  name  Trichopeltis  for  it.
