which is represented in the cf (perhaps homologically) by the united 

 coxœ 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). . . 



Sphœropœus, Brandt, 

 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. 



type ovalis, Gray. 



Sphaeropœus.

 This species is so different from all others in its abruptly sloping 

 1 st 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. 

 cf — Anal tergite evenly rounded. 



Forceps; I s * pair with immovable finger crescentic and incurved;

 very much the larger of the two and is produced inwardly into a
