Solifuge in the British Museum. 91 
Loc. Interior of S. Africa (Harl of Derby). 
The above-given measurements show that this species 
further differs from hostél’s in having the legs shorter as com- 
pared with the width of the cephalic plate. 
In the structure of its mandibles it seems to approach 
S. producta of Karsch (=vincta (C. Koch), Simon); but the 
teeth on the lower jaw of the mandible are more to the front, 
the curvature of the flagellum is much more abrupt, the upper 
jaw projects further in front of it and is not hooked at the 
apex. 
Solpuga Marshall, sp.n. (Pl. IV. figs. 9, 9 a.) 
¢g. Colour of head, mandibles, palpi, and anterior three 
pairs of legs reddish brown ; the distal segments of the fourth 
leg, 7. e. from the tibia to the tarsus, black ; abdomen with a 
broad median black band, which spreads in front on to the 
posterior thoracic segments,+clothed at the sides with long 
yellowish-white hairs. 
Head exceeding in width the length of the protarsus of 
palp, but shorter than tarsus and protarsus taken together. 
Mandible with upper fang straight and parallel-sided from 
base to point, where, in addition to the terminal fang, it is 
armed with two blunt teeth ; flagel/um almost as in S. hostilis, 
White, but rising from an upstanding semicircular plate and 
running forwards almost up to the apex of the fang, then 
turning abruptly backwards and terminating in a slightly 
upcurled point above the ocular tubercle. 
Palpi short and moderately robust; the protarsus much 
less strongly bowed than in hostilis. 
Measurements in millimetres.—Total leugth of trunk 21; 
width of head 5; length of mandible 9, of palp 22, of its 
tibia 7, tarsus and protarsus 7; length of fourth leg 36, its 
tibia 7°2, protarsus 6:2. 
Loc. Fort Salisbury (Mashonaland). A single specimen 
obtained by Mr. G. A. K. Marshall, to whom I have great 
pleasure in dedicating the species. 
This species is nearly allied to S. hostil’s and derbiana, but 
may be recognized from both by the form of its mandibles. 
Genus RHAX. 
thax miranda, sp.n. (PI. IV. fig. 1.) 
_.g-—Colour. Head black, with a small yellow spot on each 
side near the ends of the anterior border; mandibles entirely 
black; posterior two thoracic segments yellowish white ;
