abdomen : in villosa, there are only three pairs of black blotches on the abdomen 
anteriorly, these being followed immediately by the black patch which covers 
all the posterior tergites: in chelicornis var. pubescens there are six or seven 
pairs of black blotches in front of the continuous bands. In both species, 
the posterior abdominal sternites are infuscated throughout their breadth, 
instead of at the sides only, as in females of hostilis or derbiana : the blackening 
is more intense at the sides however. The hind borders of the genital plates 
are considerably produced in both species. 
The terminal fang of the lower jaw is not quite so elongated as in the 
pubescens form of chelicornis , which this species resembles in the possession 
of a dense pile of short hairs on the upper surfaces of the distal segments of 
the palp in both sexes, but more especially in males: the distance from the 
tip of the fang to the apex of the first tooth is about equal to if times the 
distance between the apices of the two large teeth.

The type and only known specimen is indefinitely located Gt. Namaland.

The type came from Quibis, S.W.A., near the Karasbergen.

The types came from localities near the Karasbergen, S.W.A., viz. 
Kraikluft, Narudas Sud, and from between Kraikluft and Sandmund. Stridu- 
latory ridges are well developed on the chelicerae of the male. The lower jaw 
has numerous feathered bristles on its inner side, and on the outer side is a 
feeble but distinct ridge distally. The colouration of the abdomen has a general 
resemblance to that of hostilis, and the species is no doubt diurnal in habit. 
The tergites are entirely brown except for slight infuscation in the middle, 
which is faint in the anterior segments but more pronounced posteriorly, the 
three posterior tergites being dark brown throughout: the soft skin between 
the tergites is also blackened mesially. On each side of the tergites, the soft 
skin is blackened as a continuous longitudinal stripe. Below this, the sides 
are silvery. The sternites are infuscated laterally.

Dr Purcell records this species from the divisions of Namaqualand, 
Carnarvon, Uitenhage, Robertson and Swellendam. It is known to me from 
Alicedale (F. Cruden), Dunbrody (V. Powels), De Aar (Miss E. Friedlander) 
and Victoria West (B. Marais). 
Stridulatory ridges are well developed on the chelicerae of the male. In 
the lower jaw of the male, the patch of bristles on the inner surface includes 
two or three curved spines distally, thus differing from hostilis, and most 
other species, where the patch is composed of bristles of more uniform size : the 
stouter curved bristles and spines are mostly in a single line along the lower 
portion of the extensive patch of bristles. There are numerous feather bristles 
which, however, like those of the upper jaw, are not very densely feathered. 
There is a very long interval between the first and second teeth of the lower 
jaw. On the outer side of the lower jaw is a distinct keel. In the female the 
posterior margins of the genital sternite are rounded.
