h  Labral  pores  4  +  4  ;  the  transverse  sulcus  obsolete  and  replaced  by 
a  deep  groove,  the  area  behind  which  is  elevated  and  bears  the 
pore;  longitudinally  banded  Spirobolellus.

chrysoproctus. 
b9.  Dorsal  flavous  band  divided  by  median  black  band,  anal  tergite 
fuscous.

Rhinocricus,  Karsch  (emend.) 
Head  with  a  complete  or  nearly  complete  median  sulcus:  labral 
pores  2  +  2.  Eyes  subcircular  widely  separated.  Antennce  short,  the 
2Dd  segment  the  longest,  the  rest  subequal. 
First  tergite  or  collum  gradually  narrowed  laterally,  its  lateral  border 
generally  convex;  the  2**  segment  projecting  below  the  1st.  The  trans- 
verse sulcus  on  the  segments  complete  dorsally  or  obsolete.  Pores 
situated  just  in  front  of  it.  Some  of  the  segments  generally  furnished 
with  the  scobina.  Sterna  transversely  striate.

Celebes:  Luwu.  Several  specimens. 
Colour  (in  alcohol)  olivaceous  or  brunneous  with  paler  or  redder, 
hinder  borders  to  the  tergites;  head  olivaceous,  with  labral  margin 
reddish.  Antennae  ochraceous.  Feet  ochraceous,  darker  at  the  base. 
Body  robust,  narrowed  at  the  posterior  end. 
Head  convex,  smooth,  polished,  marked  throughout  by  a  feeble 
vertical  sulcus  which  becomes  still  fainter  below;  labral  margin  angu- 
larly excised,  with  two  pores,  one  median  and  one  lateral.  Eyes 
separated  by  a  space  equal  to  about  four  times  a  diameter,  composed 
of  about  28  ocelli  arranged  in  5  transverse  rows.  Ântenuœ  short, 
not  so  long  as  the  face,  about  equal  to  the  width  between  the  eyes, 
the  segments  narrowed  at  the  base,  subequal  in  length,  the  two 
distal  hairy,  the  rest  smooth. 
The  first  tergite  smooth,  the  lateral  portion  feebly  margined  in 
front,  not  striate,  the  angle  rounded  and  not  extending  so  low  as  the 
inferior  extension  of  the  second.  The  rest  of  the  somites  finely  striolate 
below  and  in  front,  smooth  behind,  the  transverse  suture  weak ,  visible
