250 Mr. R. I. Pocock on the Genera and 
a. Legs short, posterior three pairs very ro- 
bust, with their distal segments strongly 
spined ; fourth leg subequal to third in 
length, without claws, its coxa and tro- 
chanter (three basal segments) as long 
as the rest of the limb and furnished 
with only three malleoli* (according to 
Su ACOA A ots He Qian poe scr, cS eee Fam. HEx1sopoDID4&, nov. 
b. Legs long or short, fourth pair at most 
weakly spined and considerably longer 
and stronger than the others, armed with 
two claws, its coxa and trochanter 
much shorter than the rest of the ap- 
pendaye and bearing five malleoli on each 
side in the adult t. 
a’, Abdominal tracheal stigmata lying be- 
hind and under the posterior margin of 
the second and third sternal plates and 
protected by comb-like plates; basal 
segment of claws hairy; tarsus of palp 
freely, movable nese staal Aes: Fam. GALEODIDZ (s. s.). , 
6, Abdominal tracheal stigmata visible 
upon the posterior margin of the second 
and third sterna, lying in a triangular 
excision of the plates; claws free from 
hairs ; tarsus of palp immovably fused 
to the protarsus © 4/00: sepa ao Js,- Fam. SoLPuGIpDaz (8. s.). 
a’, Anal segment small, subcircular, the 
aial aperture extending from its in- 
ferior almost up to its superior edge. Subfam. Solpugine, nov. 
b?. Anal segment of large size, trans- 
versely elliptical, the anal aperture 
not extending more than halfway 
from its lower border towards the 
dorsal border'§ <Seeeal akan oar Subfam. Rhagodine, nov. 
* I have applied the term madleolus to the racquet-shaped organs 
situated upon the basal segments of the fourth leg. 
+ The genus Gnosippus, Karsch, represented by one species from 
Egypt, and probably belonging to the Solpugide, is described as having 
no claws on the legs of the fourth pair. It is also said to be peculiar in 
that the coxa of this limb is nearly as long as the femur, But a glance 
at the figure of this appendage shows that Karsch has mistaken the coxa 
jor the trochanter. As a matter of fact, the trochanter is scarcely longer 
than usual; but, if the figure is to be trusted, it presents the unique 
character of being undivided instead of bisegmented as in the rest of the 
order. The segment which Karsch refers to as the trochanter is the 
segmented basal end of the femur. 
t ? Zombis of Simon, based upon a specimen from Jaffa, and said to be 
characterized by the possession of only three pairs of malleoli, three 
tarsal segments on the third and fourth legs, and only a pair of sete on 
the ocular tubercle. But, as is explained below (p. 258), the number of 
malleoli, of tarsal segments, and of ocular sete is often but an indication 
of immaturity, and that it is probably so in the case of Zombis may be 
inferred from the fact that the type, pusiola, is only 9 millim. long.
