Nemesoides hespera sp. nov. 
Male—Carapace, sternum, labium and endites and legs yellowish. Chelicere 
darkened distad by the black teeth of the rastellum. Abdomen yellowish beneath; 
light brown above, with three longitudinal rows of short, black, transverse marks. 
Chelicere long and rather slender, extending almost directly forward, not at all 
geniculate, the lower teeth of rastellum stout. Anterior row of eyes procurved in 
such manner that the line tangent to the lower edges of the median eyes passes 
through or near the centers of the laterals; lateral eyes with diameter twice that 
of the medians; median eyes their diameter apart. Anterior and posterior lateral 
eyes equal or very nearly so, separated by less than half their radius. Posterior 
median eyes nearly of same size as the anterior medians from which separated by 
their radius, closer to the posterior laterals. Tibia I in male with spur or process; 
strongly spined; a series of long, stout spines along each side, fewer smaller ones 
beneath, typically a short, oblique row of four close-set and especially stout spines 
at the ectoventral corner of the distal end. Metatarsus I with a strong angle, or 
process, at-middle of the ventral edge. Palpal organ as shown in pl. 1, fig. 1. 
Length, 10 mm. Length of cephalothorax, 5 mm. Length of tib. + pat., 1.5 mm.; 
of tib. + pat. IV, 5.5 mm. 
Type M. C. Z. 379. Claremont. Wm. A. Hilton coll. 
DICTYNID 
Amaurobius nigrellus sp. nov. 
Female—Carapace dusky chestnut to nearly black. Sternum solid black. Labium 
and endites black or blackish excepting across tips. Legs dusky brown, the femora 
darker, blackish. Abdomen above and laterally blackish brown, the background black 
lightened by numerous minute yellowish dots; venter mesally immaculate black. 
Anterior median eyes their diameter apart, once and a half as far from the laterals. 
Posterior row of eyes but little longer than the anterior; median eyes nearly twice 
their diameter apart, and almost two and a half times their diameter from the 
laterals. Area of median eyes wider behind than in front and longer than wide. Tibia 
I unarmed. Anterior metatarsi well spined beneath. Tibia IV with four spines 
beneath, these in a longitudinal line with an extra one at distal end. Tibie III and 
IV with a small spine at the base above, in this differing from the other known 
North American species. Lower margin of furrow of chelicere armed with two 
teeth. Epigynum a plate subcordate in outline with a median longitudinal band ex- 
tended laterad on each side behind. 
Length 6 mm. Length of tib.+ pat. I, 3 mm.; of tib. + pat. IV, the same. 
Type—M. C. Z., 374. Cal., Claremont. Prof. Wm. A. Hilton. 
Parauximus gen. nov. 
Resembles Auximus in eye characters, but eyes of both rows nearly equidistant. 
It differs in having the lower margin of the furrow of the chelicere armed with 
eight teeth, instead of four or five, of which the most distal instead of the most 
proximal is largest; upper furrow with three teeth of which the median is largest. 
A notable feature of the genus is that the patella of the male palpus, at least in the 
genotype, bears a stout apophysis. 
Genotype—P. tardatus sp. nov.
