76 Mr. R. I. Pocock on some 
being smaller and in having the hairy clothing of the legs 
thicker. Apart from colouring, these are, perhaps, the first 
distinctive characters to strike the eye. The colouring, 
however, is very different, intrepidus being provided with a 
continuous median dorsal black band, the sides of the abdo- 
men being clothed with white or yellow hairs, and the hairs 
on the distal segments of the legs and palpi being of a bright 
greenish yellow, those on the distal half of the appendages 
and on the head and mandibles being greyer. ‘The spine- 
armature of the legs is as in arabs, except that the spines are 
perhaps longer. Moreover, the lower surface of the tibia 
of the second, third, and fourth legs is furnished with a few 
hairs which are markedly stouter than the rest, and the ante- 
rior spine at the distal end of the lower surface is considerably 
stouter, and there appear to be always three pairs of spines on 
the first tarsal of the second and third legs. In the male the 
tarsus of the fourth pair of legs is clothed beneath with 
ordinary slender setiform hairs, and the fifth (and sixth) sterna 
of the abdomen are furnished with slender bacilliform spines, 
as in arabs. 
I need hardly add that Simon’s reason for changing the 
name intrepidus into Savignyz, because Dufour wrongly 
identified one of his species as ¢ntrepidus, is utterly untenable. 
Birula’s Savignyt (Zool. Anz. 1890, p. 206), from Turkestan, 
which has six spines on the protarsus of the fourth leg, is 
probably different from what I believe to be cntrepidus, as, 
indeed, might have been imagined from the locality. So, too, 
does Simon’s scalaris, from Central Abyssinia, differ in having 
three pairs of spines confined to the distal half of the protarsus 
of the fourth leg. It resembles my specimens, however, in 
its small ocular tubercle ; and I am not inclined to lay very 
much stress upon the presence of an extra spine upon the 
posterior side of the protarsus of the fourth leg, because there 
seems to be a tendency in this species for hairs to become 
spiniform, and in two of the British Museum specimens, 
which otherwise do not seem recognizable from the rest of the 
examples of ¢ntrepidus, there are six spines on this protarsus, 
the additional one being, however, not a pair to the one that 
is usually unpaired, but occupying a corresponding position on 
the anterior surface, but nearer the proximal end. One of the 
examples presenting this is a female from Oran, the other 
a male without locality. In addition to these two, the 
Museum has another example (a female, without locality), 
three (two males, one female) from Aden, one (female) from 
Perim Island, and two (male and female) from the island of 
Shadwan in the Red Sea.
