New Californian Spiders 
RALPH V. CHAMBERLIN 
The new spiders described below were found recently while identifying a col- 
lection from Claremont received from Prof. Hilton and one made by the writer in 
the same region in 1909 and 1913. A few forms from other localities noted in mak- 
ing comparisons are also included. 
AVICULARIIDAE 
Hexura fulva sp. nov. 
Carapace and sternum with labium and endites yellow of light reddish cast, un- 
marked excepting for the solid black interocular area. Legs pale yellowish brown 
without the reddish tinge. Chelicerae typically a little darker than the carapace. 
Abdomen grey above and either wholly unmarked or sometimes showing a short 
median longitudinal pale line at base; venter paler excepting toward the spinnerets, 
where darkened; spinnerets pale brown like the legs. Chelicerae long, clothed 
above on mesal portion with long sete which are more abundant on the anterior face 
below. Anterior lateral eyes much the largest, less than their long diameter apart, 
scarcely three times the diameter of the medians. Anterior median eyes about their 
radius apart, between two-thirds and three-fourths the diameter of the posterior 
medians, which are smaller than the posterior laterals. Tibie I and II armed beneath 
with 3-1-1 spines, the two unserried spines being at distal end. Méetatarsi I and II 
armed beneath with 3-3 spines. Spinnerets with articles proportioned much as in 
picea, the terminal article being pointed and subannulate, but the length rather shorter 
than the width of the abdomen and much shorter than its length. 
Length, 9 mm. Length of cephalothorax, + mm. Length of tib.+- pat. I, 3 mm.; 
of tib. + pat. IV, 3.2 mm. 
Type—M. C. Z. 380. Claremont. 
A much lighter colored species than ficea, the genotype, and differing in the 
much shorter spinnerets, in having 3-3 spines instead of 2-2 below on metatarusus I, 
in having the anterior lateral eyes scarcely three times instead of more than four 
times the diameter of an anterior median, in the proportionately broader endites, etc. 
Nemesoides gen. nov. 
Pars cephalica of moderate size. Fovea thoracica moderate, recurved. Anterior 
row of eyes procurved, median eyes much smaller than the laterals. Laterel eyes 
on each side less than their radius apart, the anterior scarcely larger than the pos- 
terior. Rastellum of chelicere well developed, the teeth long and stout. The labium 
broader than long, unspined. Endites armed at base with a patch of slender spines. 
Sternum with a pair of large impressions united at middle and in transverse line 
with them, near, but separated from, each lateral margin a much smaller impression. 
Tarsal claws with teeth numerous, in two sinuous series. ‘Tarsi and, in part, meta- 
tarsi of first two pairs of legs scopulate. Tarsi of last two pairs of legs spined (male, 
genotype.) Metatarsus IV shorter than tibia IV. Superior spinnerets large, four- 
jointed, the distal joint short, rounded, shorter than the third and much shorter than 
the second. ‘Tibia I of male with spur. 
Genotype—N. hespera sp. nov. 
This genus falls in Simon’s group Nemesiex in its more restricted sense.
