(b) 1 ad. ? (No. 12394) with nest and cocoon from Ashton Station, 

 Eobertson Division, collected by Mr. T. O'Connor. 



Cocoon. The cocoon resembles that of S. quadratimaculatus n. sp., 

 described further on (p. 79). 



Nest. The nest resembles that of S. erythrognathus n. sp., but is 

 smaller. The lid was firmly fastened down, as is usually the case 

 during the hatching period, being attached all round the lower edge 

 to the lining of the tube by means of silk. The dimensions are as 

 follows : Width of lid taken parallel and at right angles to hinge 

 22 mm. ; width of hole at 10 mm. from edge 16f ; width of hinge 

 15 ; average thickness of lid about 4 ; length of occupant 29^-, width 

 of its carapace 7f . 



3. STASIMOPUS QUADRATIMACULATUS n. sp. 



Specimens. ad. ? ? (types ; Nos. 12397-12402) with 5 of the 

 nests, 2 also with cocoons, from the low veld at the Montagu 

 Baths, collected by my wife and myself in November, 1902. Also, 

 2 immature specimens (one with the nest) from the same locality. 



? ? . Colour as in brevipalpis n. sp., but the abdomen with a 

 small but very distinct quadrate infuscate mark anteriorly above and 

 generally also a large infuscate patch posteriorly above the spinners. 



Carapace as long as the patella and tibia together with f or the 

 whole of the metatarsus of first leg and as the tibia and metatarsus 

 together with f or the whole of the tarsus of fourth leg. 



Eyes much as in erythrognathus n. sp. ; the posterior median eyes 

 sometimes less than their own diameter from the posterior laterals. 



Legs. Length of tibia of first leg equalling or slightly exceeding 

 (rarely less than) the width of the posterior row of eyes and often 

 only slightly less than the length of the metatarsus ; apical patch of 

 spinules on the tibia small, occupying at most ^ of the length of the 

 dorsal surface ; dorsal band on metatarsus I occupying from ^ f of 

 the length of the dorsal surface. Third leg with 12-21 spines in the 

 anterior and 14-24 in the posterior band on the metatarsus ; the 

 distal dorsal spinules on the patella mostly setiform and sometimes 

 absent. Fourth leg with 8-11 regularly arranged, subsetiform spines 

 in the infero-posterior apical tuft of the metatarsus. Legs otherwise 

 as in erythrognathus n. sp. 



Measurements of adults. Total length 27-32 mm. ; length of cara- 

 pace 10-11 ; width of ocular area in largest ? 3^. 



The two immature specimens have the posterior eyes closer 

 together on each side.
