flat, oval in outline, but broadly truncated at the hinge, its diameter 

 taken at right angles to the hinge equal to the diameter taken parallel 

 to the hinge (each being 19 mm.). 



The under side of the lid is lined with white silk, but the upper 

 surface is rough and covered with clay. At the edge the lid broadly 

 overlaps the edge of the hole. Width of hinge about 13 mm. ; 

 diameter of hole at 1 cm. from opening 13 mm. ; width of hole at 

 opening 15 mm. ; width of carapace of occupant 5^ mm. 



Synoptic Table of the Adult Females of HARPACTIRELLA. 



a. Apical segment of spinners (measured below) J- longer than the penultimate 

 segment, and longer than the ocular tubercle. 



a 1 . Colour brownish yellow. First leg decidedly shorter than the fourth (by 

 the fourth tarsus). Uitenhage Division H. magnu n. sp. 



I 1 . Colour blackish brown. First leg subequal to the fourth or only slightly 

 shorter (by at most | of the fourth tarsus). Paarl Division 



H. lif/htfooti * Pure. 



b. Apical segment of spinners subequal to the penultimate segment in length, and 

 shorter than, or at most only slightly longer than, the ocular tubercle. 



a-. Scopula of fourth tarsus divided along the middle by a very conspicuous and 

 rather thick band of longish black setse. Metatarsus II spined at apex. 

 Posterior median eyes very small, much smaller than the laterals or the 

 anterior medians. Robertson and Swellendam Divisions 



H. doinicola n. sp. 



b~. Scopula of fourth tarsus entire or divided by a fine band or row of slender 

 sets. Metatarsus II not spined. Posterior median eyes generally only 

 slightly smaller than the anterior medians. 



f/ 3 . Carapace as long as the tibia and metatarsus of first leg. Scopula of 

 fourth tarsus undivided. Prince Albert H. karrooica Pure. 



fr3. Carapace as long as tibia, metatarsus, and f-f of the tarsus of first leg. 

 Scopula of fourth tarsus imperfectly or more or less distinctly divided by 

 a line of fine setse. 



4 . Ocular tubercle further forward, about J of its length from the 

 anterior margin. First leg shorter than the fourth by - of the 

 fourth tarsus. Cape Peninsula H. treleaveni Pure. 



b*. Ocular tubercle further back, about ^ of its length from the anterior 

 margin. First leg shorter than the fourth by almost the whole 

 length or more than the length of the fourth tarsus. Malmesbury 

 Division H. hdeucc n. sp. 



* H. liiiJitfooti may possibly be the ? of longipes Pure., to which it is closely 

 related. The female specimens doubtfully referred to longipes in a previous paper 

 (Trans. S. A. Phil. Soc., v. 11, p. 344) do not really belong to that species.
