102 ARANEIDEA. 
4. Teudis ruber, sp. n. (Tab. VII. fig. 23, ¢ .) 
Type, 2, in coll. Godman & Salvin. Total length 8-5 millim. 
Colour entirely orange-yellow, abdomen paler (the tints have probably faded). 
Posterior row of eyes straight ; eyes subequal, almost equidistant, one diameter apart. Anterior row straight ; 
centrals very small, less than half a diameter apart, the same distance from the laterals. Inferior margin 
of the fang-groove with four stout teeth. Tibia i. and ii, with 2—2—2 spines beneath, one pair apical, 
and three lateral spines on each side. Protarsi i. and ii. with one pair of long spines at the base and one 
lateral basal spine. Tarsi and protarsi i. and.ii. thickly clothed with scopuliform hairs. Patelle i. and ii. 
with two bristles. For a figure of the vulva, see Tab. VII. fig. 23. 
Hab. Guatemata (Sarg). 
5. Teudis roseus, sp.n. (Tab. VII. fig. 24, 2.) 
Type, ?, in coll. Godman & Salvin. Total length 10-11 millim. 
Colour entirely pale orange-yellow, abdomen palef, mandibles darker (the tints have probably faded). 
Posterior row of eyes almost straight ; eyes subequal, almost equidistant (centrals further apart), one diameter 
apart, Anterior row straight ; centrals much smaller, one-half a diameter apart, one diameter from the 
laterals. Mandibles 5-6 stout teeth on the inferior margin of the fang-groove. Spinulation of the legs 
asin 7. ruber. For a figure of the vulva, see Tab. VII. fig. 24. 
Hab. Panama, Bugaba (Champion). 
SILLUS, gen. nov. 
Type, 9, Sillus putus (O. P.-Cambr.). Costa Rica. 
Very similar in general structure to Teudis, but the carapace is more compressed, especially in front, while the 
caput is narrower and the eyes more closely grouped. ‘The protarsi i. and ii. have two pairs of spines 
beneath, the tibiew also two pairs; no apical pair. It differs from Anyphena in the very much smaller 
central anterior eyes. The upper margin of the fang-groove bears 4 stout teeth, the lower 13 or 14 very 
minute ones ( @ ). 
It is quite possible that several genera belonging to this group which are here held 
separate will eventually fall together. 
Males. 
A. Mandibles gibbous at the base beneath, furnished with two stout 
teeth in the middle of the basal segment beneath. Tibia of palpus 
nearly twice as long as the patella, distinctly longer than the tarsus, 
narrowed towards its base. Spine at the apex of the bulb short, 
stout, curved, but not simuous . . . . . 2. ee 6 ee.  attigpuus, O. P.-Cambr. 
B. Mandibles not gibbous at the base beneath, nor furnished with teeth 
in the middle. Tibia of palpus only one and a half times, or less, 
longer than the patella, shorter than the tarsus. 
a. Tibial spur stouter, concave, bifid or with a sharp curved spine. 
Spine at the apex of the bulb straight or slightly sinuous. 
1. Tibial spur bifid at the apex, concave beneath. Tibia one-third 
longer than the patella. ‘Terminal spine terminating in a long 
straight point, directed forwards. . . . . ~ + « « « longispina, sp. n.
