between  conspicuousness  and  inconspicuousness  with  respect  to  the 
excavation  of  the  upper  surface  of  the  caudal  segments. 
Fabeicius'  type  of  australasiae  and  Gervais'  type  of  cumingii  are 
both  preserved  in  the  Natural  History  Museum.  In  the  latter  speci- 
men the  tail  is  more  excavated  above  than  it  is  in  the  former;  but 
otherwise  there  is  no  noticeable  difference  between  the  two.  In  his 
description  of  cumingii,  G-ervais  (Ins.  Apt.  Ill,  p.  69)  says  that  the 
body  is  finely  granular  above.  This,  however,  is  not  the  case;  for  a 
lens  of  sufficiently  high  power  shows  that  what  Gervais  described  as 
granules  are  in  reality  exactly  the  opposite,  namely  punctures. 
Curiously  enough  the  late  Count  Keyserling  appears  to  have  fallen 
into  precisely  the  same  error.  For  although  he  describes  the  species 
as  granular,  yet  an  examination  of  the  examples  in  his  own  collection 
shows  that  they  are  not  granular  but  finely  and  closely  punctured. 
11.  Hormurus  weberi  sp.  n.  (Pl.  VI.  fig.  1 —  lb). 
Several  specimens  from  Luwu  in  Celebes. 
Colour  —  trunk  above  rufo-piceous  ;  palpi  somewhat  darker  than  the 
trunk;  legs  and  caudal  vesicle  and  lower  surface  ochraceous. 
Céphalothorax  usually  a  little  longer  than  wide,  at  least  not  wider 
than  long,  more  convex  from  side  to  side  than  in  H.  australasiae, 
closely  punctured  and  finely  granular,  the  frontal  portion  nearly  smooth 
and  punctured,  the  lateral  and  posterior  portions  sparsely  granular, 
with  smooth,  neither  granular  nor  punctured,  areas;  the  middle  third 
of  the  anterior  border  deeply  excised ,  the  external  thirds  nearly 
straight;  the  ocular  tubercle  deeply  cleft,  situated  in  the  anterior  half 
of  the  céphalothorax;  the  median  eyes  large  and  very  close  together, 
the  distance  between  them  being  about  half  a  diameter  or  even  less; 
lateral  eyes  large  and  very  prominent,  about  equal  in  size  and  equi- 
distant from  each  other. 
Tergites  finely  punctured,  rugulose. 
Sternites  finely  punctured,  entirely  smooth. 
Tail  about  2-|  times  the  length  of  the  céphalothorax  in  Ç  and 
nearly  2f  in  the  cT  ;  the  segments  gradually  increasing  in  length  and 
all  of  them  longer  than  wide;  the  upper  surface  of  all  of  them,  ex- 
cept of  the  5th,  mesially  excavated,  the  sides  rounded,  very  weakly 
granular,  and  noticeably  without  an  enlarged  terminal  granule;  the
