410 Mr. R. I. Pocock on 
Tarsi as in Zephronia or approaching in structure those of 
Spheropeus. 
Type S. rotundatum, Brandt. 
Distribution. 8. Africa. 
Spherotherium monticola, sp. n. 
&. Colour piceo-olivaceous. 
Nuchal plate marginally punctured; the other terga coarsely 
but irregularly punctured. 
Anal tergite punctured and hairy and marked mesially with 
a narrow vertical area, densely beset with piliferous punctures. 
Length 17 millim. 
Loc. Table Mountain (H. A. Spencer). 
Spherotherium granulatum, sp. n. 
Colour deep green, with posterior borders of tergites ferru- 
ginous. 
Related apparently to S. rotundatum and compressum, but 
differing from both, as from all the other species of the genus 
known to me, in having the anal tergite finely and thickly 
granular. 
Length 15 millim. 
Loc. Port Klizabeth (H. A. Spencer). 
Genus ZOOSPH ERIUM, nov. 
Closely allied to Arthrosphera in the vulva, but having 
the external of the two distal lamine of this organ deeply 
notched. Antenne usually long, with the apical segment 
cylindrical in both sexes. 
Tarst nearly intermediate in structure between those of 
Arthrosphera and Zephronia. 
Type Z. neptunus (Butler). 
Distribution. Madagascar. 
Genus ARTHROSPHARA, nov. 
Vulva composed of three distinct segments, one proximal 
and the others distal, arranged in the form of a cone. 
Copulatory feet. Movable digit of anterior pair armed with 
lobe-like teeth and much larger than the immovable digit, 
with its basal portion often segmented: in the posterior pair 
the immovable is compressed and blade-like, with its cutting- 
edge finely toothed ; the movable not segmented, armed poste- 
riorly with a set of granuliform teeth and internally with two 
membranous processes.
