Pedipalps. Scopula of tarsus divided by a weak line of setae ; 

 tibia with 2 weak apical spines on under surface. 



Vulval plate with a pair of round dark marks showing near posterior 

 lip centrally. 



Measurements. Chelicera to end of abdomen 13'5 mm. Carapace 

 6 mm. long, 5 mm. wide. 



A small subadult ? from the same locality appears to be a different 

 species from the above. 



FAMILY DIPLURIDAE. 



The specimens identified by Dr. Purcell in Ann. S. Afr. Mus., vol. 3, 

 p. 106, 1903, should not have been referred to Theleclioris as denned 

 in Hist. Nat. des Araign., p. 187, since on examination the type 

 specimen of T. australis, Pure., does not agree with the description 

 of that genus. Hence my concbusion (Ann. S. Afr. Mus., vol. 17, 

 p. 119, 1917), based on the type $ of australis, that the <$ of this 

 species of Thelechoris proved that Tlielecltoris was not synonymous 

 with Isclinothele, is no longer valid. Thelechoris and Ischnothele 

 are synonymous, as stated by Simon. Neither are the specimens 

 in question referable to Evagrus, from, which genus they appreciably 

 differ. Hewitt points out (Ann. Durb. Mus., vol. 1, pp. 132-3) 

 that Evagrus caffer, Poc., and T. australis, Pure., undoubtedly belong 

 to the same genus, which is not Evagrus and cannot be Ischnothele 

 (Thelechoris) ; hence, as he suggests, it is advisable to create a new 

 genus, for which I propose the name AUothele. 



The principal diffei-ences between Evagrus and Allothele are that in 

 Evagrus (following Ausserer's description) the spinners are shorter 

 than the abdomen ; the 1st and 2nd pairs of legs are stouter in build 

 than the remainder ; tibia I is swollen and armed below and partly 

 also on the inside with numerous very strong long spines ; tibia II 

 is short and very thick with a projecting tubercle on the inside, on 

 the end of which are 3 very long spines ; also numerous shorter spines 

 on saddle-shaped depression, on the outside ; metatarsus II has two 

 projecting txibercles below, the larger on the inside, in the upper 

 quarter, the smaller outside in the upper third ; from both there runs 

 a sharp keel down the length of the metatarsus. 



These and other characters distinguish Evagrus from the following : 



GEN. ALLOTHELE, n. gen. 



Cephalothorax moderately convex, one-fifth longer than broad ; 

 fovea slightly recurved. Ocular tubercle at least twice as broad as
