New South African Spiders. 79 



Cocoons. The white cocoon is of soft texture and subspherical in 

 shape, except on one side, which is flat and provided round the edge, 

 at least in part, with a narrow free flap (act, fig. 3). An uninjured 

 cocoon contained 43 eggs, each measuring about 2f mm. in diameter 

 (in spirits) and still at a very early stage of development (Novem- 

 ber 25th). The cocoon is placed at the bottom of the burrow.

Nests. The nest closely resembles that of S. unispinosus Pure. 

 (Ann. S. A. Mus., v. 3, p. 24, pi. 1, figs. 1-2), having the lids very 

 thick and cork-like and generally much less strongly bevelled at the 

 edge than those of the two preceding species. The lower edge also 

 is more angular and less rounded. The lids of the adults measure 

 23-27^ mm. across (taken parallel to the hinge) and 5-i 9 mm. in 

 average thickness, the diameter of the hole at 1 cm. from the edge 

 being 16^-18 mm. All the holes measure 18-19 cm. in depth, and 

 they are not enlarged at the bottom. In every case the spider was 

 found at the bottom of the hole. 



These nests abound in the open veld near the Baths, and numbers 

 of open and deserted ones were met with. 



4. STASIMOPUS BIMACULATUS n. sp. 



Type. 1 5 (No. 9942) from Willowmore, Cape Colony, collected 

 by Dr. H. Brauns, in December, 1901. 



Closely related to the foregoing. 



2 . Colour brown, the carapace behind and the 2 posterior pairs 

 of legs paler and more yellowish, the pedipalps ochraceous above 

 along the middle of the patella and tibia, the 2 posterior pairs of 

 legs and the 4 pairs of coxae pale ochraceous ; abdomen pallid, with 

 small black dorsal patch in front and a larger one behind. 



Carapace as long as the patella, tibia, and metatarsus of first leg 

 and as the tibia, metatarsus, and f of the tarsus of fourth leg. 



Ocular area compacter than usual, its width behind just equal to 

 the length of the tibia and slightly exceeding that of the metatarsus
