they pass. Some of them, as Heteropoda, carry the egg-sac tucked under the sternum ; 
others weave together a few leaves in a tubular form, making a retreat, and in this 
they conceal the egg-sac, rushing forth with startling rapidity if the retreat be handled. 
In this they resemble Chiracanthium and other Clubionids. 
Subfam. PSEUDOSPARIANTHINA. 
Spinners set upon a distinct basal segment. Apex of protarsi i. and ii. with modified membranous lobes; not 
so well developed as in Heteropodine. 
PSEUDOSPARIANTHIS. 
Pseudosparianthis, E. Simon, Bull. Soc. Zool. Fr. 1887, p. 473. 
Type P. fusca, E. Simon. Amazons. 
Posterior row of eyes procurved, subequal, equidistant ; anterior row slightly procurved ; centrals the largest 
of the eight, rather further from each other than from the laterals. Apex of abdomen attenuate ; 
spinners set upon a common basal segment. Upper margin of fang-groove with three or four larger 
teeth; lower margin with very minute teeth, very variable in number, 4-8 &c. Tibiee i. and ii. with 
2—2—2 spines beneath. Protarsii. and ii. with two long spines beneath. Tarsi compressed and 
slightly convex above. Protarsus iii. with two spines and a group of very small curved spines in the 
centre at the apex beneath; protarsus iv. with 2—2 spines and a similar group of small spines beneath 
at the apex. 
1. Pseudosparianthis variabilis, sp.n. (Tab. VIII. figg. 21, 21a, 4,9.) - 
Type, 2, in coll. Godman & Salvin. Total length 12 millim. | 
©. Carapace, legs, and mandibles orange-yellow, the former margined and mottled with streaks of brown. 
The tibie, protarsi, and tarsi of the first two pairs of legs are also darker. Sternum, mouth-parts, and 
coxee of legs somewhat paler. Abdomen pale clay-yellow, streaked and mottled with brown, including a 
pair of shoulder-bands and a series of more or less distinct ~“\-shaped bars, becoming broken up into a 
series of triangular spots towards the spinners; lateral area streaked with brown; ventral surface pale 
yellow, unicolorous. 
Structure similar to that recorded in the generic diagnosis. Eyes of posterior row nearly four diameters 
apart. Central anteriors one and three-fourths apart, the same distance from the laterals. 
Vulva consisting of an elongate cordiform central area, its apex attenuate and directed backward. 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith). 
This spider agrees neither with the diagnosis of Stasina nor Pseudosparianthis. It 
is certainly not congeneric with Eastern forms of the first-named genus, neither does it 
agree with M. Simon’s diagnosis of Pseudosparianthis, said to possess three pairs of 
spines beneath the protarsi i. and ii. (though the type, P. fusca, Sim., possesses but 
two pairs: of. Bull. Soc. Zool. Fr. 1887, p. 473). 
The present species possesses only one pair of spines beneath protarsi i. and ii., as does 
Stasina. Notwithstanding these discrepancies, or because of them, I leave this spider 
under the genus Pseudosparianthis, which will probably be found to have a wider 
signification than is suggested in the original diagnosis.
