which  is  represented  in  the  g  (perhaps  homologically)  by  the  united 
coxae  of  the  posterior  pair  of  copulatory  feet. 
The  two  genera  of  this  family  obtained  by  Dr.  Max  Weber  may 
be  recognised  by  the  following  characters: 
a.  Tarsi  almost  truncate  at  the  apex,  being  not  so  noticeably 
narrowed  in  the  distal  half,  the  superior  apical  spine  above  the 
claw  and  separated  by  a  considerable  distance  from  it.  (Distal  seg- 
ment of  the  posterior  pair  of  copulatory  appendages ,  divided). . .

type  hercules,  Brandt. 
b.  Tarsi  narrowed  in  their  distal  half,  pointed  at  the  apex  which 
bears  the  terminal  claw,  the  superior  apical  spine  close  to  the 
claw  but  distinctly  in  front  of  it  Zephronia,  Gray.

This  species  is  so  different  from  all  others  in  its  abruptly  sloping 
1st  tergite  and  in  the  thickness  and  height  of  its  anterior  margin 
that  a  detailed  description  of  it  is  not  necessary.  Since  however  the 
copulatory  organs  that  I  have  examined  differ  in  some  important  par- 
ticulars from  the  figures  that  Dr.  Karsch  has  published,  perhaps  a 
few  words  descriptive  of  these  parts  may  be  of  use.
