eighth segments have basal white bands, the fifth, sixth and seventh 
lateral white basal spots, which have a tendency to unite and form 
basal bands, there are also traces of the same on the second segment; 
first segment deep ochraceous, with two patches of dark scales in 
the middle; genitalia deep brown. Legs as in the 9 5 but the 
metatarsal bands in the fore and mid legs small or absent; ungues 
of fore and mid legs unequal, both toothed, the hind one equal. 
Length .—4 mm. 
Habitat. —Salisbury, Mashonaland (G. A. K. Marshall) (79). 
Time of capture .—February and March. 
Observations .-—Specimens sent by Mr. Marshall resemble very 
strongly S. sugens, Wied., but they differ in having the leg 
banding apical and in the structure of the £ palpi (Fig. 92). The 
thoracic ornamentation is however very similar. The species, 
judging from the number sent, is common in Central Africa.
