separable from one another, but the 4 species described may be 
distinguished as follows :— 
a. Under side of cheliceree (measured along the middle of the groove) longer than 
the sternum. Coxe of pedipalps with very few (2-4) teeth at the base. Claws 
of anterior legs with 2-4 teeth in each row; claws of fourth leg with 2-3 teeth in 
each row, but the outer claw with 0-1 tooth in the inner row. Anterior tarsi not 
distinctly scopulate below. Cape Div. .. .. ee ee Lae Lightfoovl n..Sp: 
b. Under side of chelicerze sometimes subequalling ‘bat generally distinctly shorter 
than the sternum. Coxe of pedipalps with a number (15-50) of teeth at the 
base. Claws of anterior legs with 5-9 teeth in each row; claws of fourth leg 
with 4-6 teeth in each row, but the outer claw sometimes with only 3 teeth in the 
inner row. Anterior tarsi distinctly scopulate. 
a‘. Outer claw of fourth leg with 3-4 (very rarely 5) teeth in the inner row. The 
oblique black stripes on posterior $ of the dorsal surface of abdomen more or 
less distinctly continued over the sides to the ventral surface. Posterior 
tarsi muticous or spined. Coxe of pedipalps with 30-42 basal teeth.

1. HERMACHA LANATA N. sp. 
Type: 1 § (No. 3639) collected by Mr. M. Schlechter in the 
Bokkeveld, east of Pakhuisberg, Clanwilliam Div. 
g§ . Colowr.—Carapace brown, with darker radiating stripes, the 
cephalic portion more yellowish laterally, the surface thickly covered 
in places with pale cream-coloured, long, mostly appressed, silky 
* In both sexes of the species of this genus known to me the claws of all the legs 
are biseriately dentate below, the rows being opposite to one another, composed of 
numerous teeth, and of about equal length, each extending from the base up to or 
beyond the middle of the claw. The inferior claw is minute in the anterior pairs 
of legs but distinct in the posterior pairs. The rastellum is composed of slender 
or moderately stout sete, sometimes with a few slender spines in addition. The 
anterior surface of the chelicere is always thickly covered with numerous, short, 
stout bristles, as in the other members of the family. The females may be readily 
distinguished from those of Hermachastes by the broad, dense, entire scopula which 
covers the whole under surface of the tarsi and metatarsi of the 2 anterior pairs 
of legs. The posterior spinners in both sexes are frequently very long and 
the anterior ones widely separated, as in the Dipluride, and it is very probable 
that the species described by Ausserer as Brachythele capensis belongs to this genus. 
In the adult male the tibia of the first leg is much stouter than the metatarsus and 
its outer apical spine below is stout and spur-like. By far the greater number 
of the Ctenizide usually found in collections made in South Africa belong to the 
genera Hermachastes and Hermacha.
