Heligmomerus astutus (Hewitt). 
This species, founded on an adult male example, was described as 
an Idiops (Annals Natal Museum, III, pt. 2). 
A large female example in the Rhodesian Museum, presumably- 
belonging to this species, was ‘taken in June, 1915, at Bulawayo, by 
Mr. Ericsson. It is evidently very closely related to H. caffer Puicell,. 
and may be specifically identical therewith or with H. deserti Pocock. 
It seems to differ very slightly from a Moorddrift specimen which is 
provisionally referred to caffer in the arrangement of the posterior row of 
eyes : in the Bulawayo example, the distance between the posterior 
medians is scarcely more than times as great as the distance between 
a posterior median and posterior lateral, whilst in the Moorddrift example 
the distance between the posterior medians is quite 1| times as great as 
that between the posterior median and posterior lateral. 
Pelmatorycter nudus, sp. nov. 
Type . — A single adult male example found under a stone at Little 
Wonderboom, Magaliesberg, by Mr. A. Roberts (6th June, 1915). This 
species is at once distinguished from pretoriae in the general absence of 
long hairs on the surfaces of the body and appendages. There are no long 
hairs on the anterior surface of the chelicerae and none on the legs : the 
abdomen is clothed with short fine hairs superiorly, and on the mesial 
area above, there are three pairs of short slender spines and a group of such 
spines occurs on the anterior portion of the upper surface. 
Other characters are as follows : — 
Pedipalp. — At the distal end of the femur superiorly on each side- 
is a short, dark-coloured, horny projection, and a short distance behind 
the apex the superior surface is slightly raised into two small, rather 
indistinct humps adjacent to each other. Tibia much shorter than that of 
pretoriae, but the style of the bulbal organ hardly reaches back half-way 
along the tibia. Pressed, forwards, the palp only extends as far as the 
basal fifth of tibia I. Maxilla without denticles at the anterobasal angle 
interiorly . “ 
Legs . — Tarsus I with a single spine on the posterior side near the 
apex, II with 2 spines on the posterior side, III with 3 spines on each side 
distally, IY also with about 3 on each side distally. Metatarsus I with 
3 spines at the apex inferiorly and in addition the lower surface has 
2-6 spines, II with 3 at the apex and 4 on the lower surface, 
IY with about 5-6 spines on the lower surface besides those at the 
apex, and, in addition, 2 on the posterior surface. Tibia I inferiorly with 
3 strong spines at the apex, 10 spines m 2 rows on the lower surface, also 
5-10 on the anterior surface and 1 on the posterior surface near the base. 
Patella III with 12 or 13 spines on the anterior surface and 4 on the dorsal 
surface ; IY without spines or only 1 inferiorly near the apex. Tarsal 
claws of first leg with 7 or 8 teeth in each row, of fourth leg with 6 or 7 
teeth in the inner row, and 5 or 6 in the outer row. 
Chelicerae . — The left jaw has 7 teeth in the inner row (dentition of 
right jaw abnormal).
