surfaces, particularly on the outer surface (the right-hand metatarsus 

 had over 20 spines and the left had under 10 ; the left leg was also 

 shorter). 



Pedipalps. Armed with 1 spine on outer side of base of tarsus ; 



4 apical spines on under surface of tibia, 1 median and 1 basal spine 

 on outer side of under surface, and 4-5 on inner surface of tibia. 



Measurement*. Chelicerae to end of abdomen, 13'5 mm. Carapace 



5 mm. long and 3'2 mm. wide ; spinners 2mm. long. Tibia of 1st leg 

 2 mm. long. 



Though the material is scanty and only in moderate preservation, 

 the genus Pionothele seems sufficiently distinct from Hermacha to 

 remain separate from it. 



FAMILY DI I.'LOTHELEAE. 

 GEN. DIPLOTHELE, Cainbr. 



Ol the three genera of the group, Acropliolius and Cestrotrema (>Sim.) 

 are both confined to Madagascar, and Dip!th<'1<' to India and Ceylon. 

 The following species from Rhodesia does not agree with the Mada- 

 gascan genera, but coincides rather with the Indian genus ; it differs 

 therefrom in certain respects, but the differences are not generic. 



DIPLOTHELE AECTURUS, 11. sp.

 abdomen dull blackish brown, flecked with numerous testaceous spots; 

 under abdomen testaceous with a black spot directly below the vulva. 

 Sternum, coxae, and under side of legs slightly lighter than the 

 carapace. The latter is marked with numerous infuscated lines 

 radiating from the t'ovea ; sides of cephalic region lightly infuscated; 

 ocular tubercle almost entirely black. 



Carapace. Equal in length to the tibia, metatarsus and -;, ! tarsus 

 of 1st leg, and to the metatarsus and tarsus of the 4th leg. Orna- 

 mented with appressed yellow hairs and scattered black bristles, which 

 are most numerous on the cephalic portion. Fovea small and straight, 

 cephalic edge longer and slightly procurved. 



Ocular area wider than long. 



Eyes. Anterior laterals oval, oblique, and nearly their long 

 diameter apart anteriorly ; anterior medians round and slightly 

 smaller than the anterior laterals; at least their own diameter behind 

 the latter and from each other. The anterior eve area, is thus slightly
