RECORDS AND DESCRIPTIONS OF THE ARACHN1DA OF THE 
COLLECTION. 
(Plate XV, Text figures 17-22). 
By John Hewitt. 
Order SCORPIONES. 
The Scorpion material comprises thirteen species most of which are 
represented by several specimens ; a new genus near Uroplectes, Ptrs., is 
described : also a new species of Parabuthus, Poc., and a new variety of 
Uroplectes ccirinatus , Poc. 
In most cases I have not thought it necessary to give references to 
original or other descriptions as the synonymy is now for the most part 
well established, complete bibliographies being available in the works 
which form the basis of our modern knowledge of Scorpion systematic^ in 
Sonth Africa, especially Dr. Purcell’s papers in the first two volumes of 
the Annals of the South African Museum (Capetown), and Prof. 
Kraepelin’s work on the Scorpions in “Das Tierreich”: an important 
paper dealing with the Scorpions collected by Dr. Schultze in the Kalahari 
and German South-West Africa is published by Kraepelin in Denkschr. d. 
Med.-Naturwiss. Gesell. Jena XIII, p. 247-268 (1908). 
Family BUTHIDAE. 
Parabuthus brevimanus , Thor. 
A single example from Quibis. 
Parabuthus schlcchteri , Pure. 
Two examples, one from rocks at Kraikluft, the other from the sandy 
river-bed at Wasserfall, 
Parabuthus viUpsus , Ptrs. 
Taken at Quibis (1437m.), in sandy soil at Narudas Slid, and amongst 
rocks at Kraiklufc. In the valley above Narudas Slid, Prof. Pearson heard 
an individual of this species in the act of stridulating and Mr. Methuen 
noticed the same phenomenon on other occasions amongst Parabuthi. 
Parabuthus granulafus , H. and E. 
The specimens are dark, being referable to the form described by 
Simon as fulvipes. The middle lateral crest on the fourth caudal segment 
is distinct though weak, in one adult specimen almost extending the whole 
length of the segment, but not so in another example of nearly adult size. 
Found on sandy plains and in the sandy river-bed at Wasserfall. 
Parabuthus stridulus , sp. nov. (pi. XY, fig. 1). 
This species is related to P. flavidus, Poc., P. mpsambimmsis, Pet. and 
apparently very closely so to a species recently described by Mr.'S. Hirst 
from Loangwa in Portuguese East Africa under the name of P. truculentus 
(Manchester Memoirs Vol. 56, No. 2, p. 2). 
Type. A single male specimen, probably not quite adult, from 
Liideritzbucht, Nov. 26, 1912 ; T. M. Cat. Scorp. No. 1030 in the Transvaal 
Museum Collection. 
Colour yellow except for the sting which is dark brown. 
Carapace granular throughout, except on the ocular tubercle where 
it is quite smooth. Length and breadth subequal.
