interrupted or more or less continuous, but very mvicli 
weaker tliough more numerous than those on the second 
segment. The last tergite is very finely and closely g-ranu- 
lated over the whole length of the median area. Middle 
lateral keel of segment IV very weak, but distinct. Ocular 
tubercle quite smooth. Vesicle very deeply excavated at 
the base superiorly Male of P. stridulus Hewitt. 
(p) Caudal segment I only shallowly excavated superiorly, the 
stridulatory area entirely composed of very fine granules, 
as is also the case on the last tergite. Ocular tubercle 
smooth above. Middle lateral keel of segment IV weak, 
obsolete in the anterior fourth of the segment.

This species was recorded from Umtata, but Miss Pegler, who collected 
the types, informs me that the actual locality is Mqanduli. The species 
is known to me from East Zululand (Natal Museum) . The Transvaal Museum 
has a very young specimen, apparently referable to this species, from 
Arnhemburg, Carolina District, and an adult from Clearwaters, near 
Haenertsburg. Prof. Kraepelin has described a small specimen, only 
23 mm. long, from Umfuli River, Mashonaland, under the name of P. pegleri 
var. nigrinianus Kraep. (13). The specimen has 13 pectinal teeth, movable 
finger with 6 flanking granules anterior to the main rows, and the middle 
lateral keel of caudal segment IV is distinguishable. 
According to Kraepelin, this genus is intermediate between Lychas 
C. L. Koch, and Odorituriis Karsch. It differs from Lychas in the greatly 
enlarged basal pectinal tooth of the female, and in the presence of two 
external flanking teeth instead of only one, alongside the enlarged basal 
tooth of each main row on the movable finger : it differs from Odontiirus 
in the presence of only one tooth, instead of two, on the immovable finger 
of the chelicera. I am inclined to think it will eventually rank as a sub- 
genus Lychas. It is held to be the same as Lychas by Mr. Hirst.

We have what seems to be this form from Redhouse (Mrs. T. V. Paterson).
