394 APPENDIX C. 
up with the sete and not always easy to distinguish; the tarsi 
4-segmented, the basal segment a little longer than the other three, 
armed with five pairs of spines below, the second segment with a 
pair of long spines; the third unspined, and the fourth with a pair 
of long spines; tibia of fourth leg with three spines in front and 
two behind ; tarsus composed of seven segments, the basal with 
five pairs of spines, the second, third, fifth and seventh with one 
pair each. 
Measurements in millimetres: total length of body 25; of 
head, 5; width of head, 7.5 ; length of mandible, 9; of palp (from 
base of femur), 30; of fourth leg from base of femur, 30. 
Two male specimens, of which the label was unfortunately 
obliterated. 
This species which apparently falls into the genus Zevza differs 
from the species of So/puga in having only two long bristles in 
front of the ocular tubercle instead of a thick cluster, and the 
extremity of the rostrum somewhat strongly deflexed, whereas it 
is horizontal in Solpuga. It is evidently allied to the Algerian 
Zeria persephone, Sim., which is known to me merely from frag- 
ments of a female specimen, the two having apparently the same 
bristle-armature on the ocular tubercle; but the rostrum of ferse- 
phone appears to be horizontal at the tip like that of So/puga. 
Liton fuscipes, sp. n. 
Closely related to B. brunnipes, Poc.) from which it differs prin- 
cipally in color, the tibia, protarsus, and tarsus of the palp being 
wholly infuscate, as well as the distal end of the femur; the remain- 
ing appendages are also more infuscate ; the whole of the femur, 
with the exception of a small area at the base, and the tibia of the 
fourth, being uniformly brown. In B. drunnipes, as in Galeodes 
arabs, the palpi have a variegated appearance, owing to the fact 
that, although mostly brownish black, the tarsus, the extremities of 
the protarsus, and of the tibia are yellow; the same pattern obtain- 
ing in the fourth leg, the joints being yellow. 
In fusctpes, too, the dentition of the mandibles is stronger, the 
teeth being both larger and sharper. In other characters, how- 
ever, such as spine-armature of legs, etc., the two are apparently 
alike. On the inner side of the apex of the protarsus of the palp 
there is a very distinct spine amongst the sete.
