Species of Tropical African Solifuge. 251 
Family Hexisopodida. 
This family contains the single genus Heaisopus, repre- 
sented by two species confined, so tar as is at present known, 
to South Africa. The generic synonymy is as follows :— 
Aellopus, ©. Koch, Arch. Naturg. 1842, pt. i. p. 354 ; id. Uebersicht des 
Arach.-syst. pl. v. p. 97 (1850) (nom. preocc.). 
Hexisopus, Karsch, Berl. ent. Zeitschr. xl. p. 109 (1879). 
The two described species are :— 
(1) LHexisopus lanatus, C. Koch, Arch. Naturg. 1842, pt. i. 
p- 354; id. Die Arachniden, xv. p. 102, fig. 1439 (sub 
Aellopus). 
Loc. Cape of Good Hope. 
(2) Hexisopus fodiens, Simon, Ann. Soc. Ent. France, 1887, 
p. 374, pl. vi. figs. 6 & 7. 
Toc. Kalahari Desert. 
The British Museum has no representative of this inter- 
esting Arachnid, 
Family Galeodida (sensu stricto), 
Genus GALEODES, Olivier. 
Galeodes, Oliv. Encycl. Méthod. vi. p. 579 (1791). 
Rhax, Hermann, Mém. Ins. Aptérol. pp. 13 & 16 (1804). 
Type araneoides, Pallas. 
Olivier established the genus Galeodes for the reception of 
two species, namely Phalangium aranoides of Pallas and the 
South-African species which he himself described as setégera. 
C. Koch (Arch. Nat. 1842, pt. i. p. 350 &c.) first dismembered 
the genus and applied the term Galeodes to the araneotdes 
section, thus selecting the latter as its type. 
Rhax of Hermannis stated by its founder to be synonymous 
with Galeodes of Olivier. Consequently C. Koch had not 
the power to apply the name to species not included by 
Olivier under Galeodes. 
The genus (raleodes nearly resembles Rhagodes (cf. infra) 
in distribution, being essentially a Palearctic torm, but 
extending into Somaliland, where it is represented by the 
Arabian and Egyptian species G. arabs, C. Koch.
