white hairs at the sides, the dorsal stigmata also ringed with white, 

 as in Eresus fumosus, Koch. 



Carapace with the cephalic portion narrow and not so high as in 

 collinus, the width of the head being equal to the tibia, metatarsus, 

 and about -I-J of the tarsus of first leg, equal to or slightly shorter 

 than the distance from the fovea to a line joining the hind margins 

 of the posterior median eyes, but slightly less than the width of the 

 thorax. 



Eyes much as in collinus, the posterior medians perhaps a trifle 

 smaller. 



Vulva is in PL X., fig. 9, the posterior median portion rectangular, 

 truncated, with a small cavity at each hind angle. 



Legs short, the length of the carapace * being equal to the patella, 

 tibia, metatarsus, and J— J of the tarsus of first leg. 



Length of carapace and abdomen 11 mm. 



2. Dresserus laticeps, n. sp. 



1 ? (No. 12831) from Tsabis, 20 miles N.E. of Concordia, Nama- 

 qualand Div., Cape Colony (/. H. C. Krapohl, 1902). 



Carapace as long as the patella, tibia, metatarsus, and about 

 \ of the tarsus of first leg, the cephalic portion reddish-black, very 

 high and broad, flattened above, rising abruptly behind far above the 

 height of the fovea, its width equal to the patella, tibia, and at least 

 i the metatarsus, and to the tibia, metatarsus, and § of the tarsus of 

 first leg, and considerably exceeding the distance from the fovea to 

 the anterior margin of the ocular tubercle. 



Posterior median eyes moderately large, about 1J diameters apart, 

 their distance from the anterior laterals equal to 3 diameters at least. 



Abdomen pale yellowish, covered with olive-brown hairs. Vulva 

 as in PI. X., fig. 10, the lateral emarginations rather shallow. 



Length of carapace and abdomen 15 mm.

Loxosceles spinulosa, n. sp. 



1 2 (No. 7915) from the Pass at Avontuur, near Stormsvlei, 

 Swellendam Div. (IF. E. P., August, 1900). 



* Length of carapace is measured between 2 parallel lines touching the 

 anterior and posterior margins and includes the ocular tubercle.
