FAMILY ERESIDAE. 

 GEN. EKESUS, Walck. 



ERESUS PURCELLI, n. sp. (Plate XXIX, fig. 1). 



Specimens. One ? (No. B 2435, Type), E. London (Dr. W. F. 

 Pnrcell, 9/05). 



Colour. Cephalothorax almost black, becoming redder posteriorly, 

 aud with a light border above the pedicel ; chelicera black, legs 

 red dish -brown in colour, posterior ones slightly lighter, anterior ones 

 darker distally. Abdomen dull testaceous in colour, and with short 

 scanty hairs only ; no white rings round dorsal stigmata ; under 

 surface infu seated around spinners. Sternum dark red brown, coxae 

 and under surface of legs slightly lighter. 



Cephalothorax. Surface clothed with appressed dark 'hairs ; punc- 

 tate, but not spined. Length equal to patella, tibia and metatarsus of 

 1st leg, and very slightly exceeding tibia, metatarsus and tarsus ; 

 width equal to patella and tibia, and slightly exceeding metatarsus 

 and tarsus of 1st leg ; also reaches from fovea to hind margin of 

 posterior median eyes. Cephalic portion raised, but not abruptly, 

 above thoracic portion, both being approximately equal in width. 



Eyes. Posterior medians large ; about 1| diameters apart, and 

 about 2 diameters from the anterior laterals ; othei'wise as in E. nama- 

 quensis (Pure.). 



Sternum and chelicera spineless. 



Legs. Without spines on coxae or femora, or on patellae of anterior 

 legs, but clothed with long hairs as in E. namaquensis. 



Pedipalps. "With some long bristle-like spines on inner and under 

 surfaces of tarsus ; otherwise spineless. 



Vulva. Ks in Plate XXIX, fig. 1. 



Measurements. Total length 17'5 mm. long. Carapace 6 mm. long 

 and 4 mm. wide. Though only one specimen is available for descrip- 

 tion, the species has been founded since the lack of spines on the 

 under surface of femora, coxae, etc., of 1st two pairs of legs, and from 

 the sternum and carapace is apparently unusual in the S. African 

 species of this genus. 



ERESUS DEPRESSUS, n. sp. (Plate XXIX, fig. 2A-B). 



Specimens. Numerous ? $ from Hanover and neighbouring 

 localities (Types, No. 12852). Collected by Mr. S. C. Cronwright
