Psilochorus california sp. nov. 
Carapace, sternum, and legs yellow or the carapace and legs proximally of pale 
brown cast; the femora proximally and the patelle and tibie at ends often tinged 
with bright red. The head and the furrows commonly darker than other parts of 
carapace, with the eyes enclosed in black. The abdomen to the naked eye appears grey, 
commonly of a greenish tinge; under the lens it shows on the sides numerous light, 
somewhat silvery, spots and above a basal pale mark, with several pairs of dark spots 
enclosed by the light ones and often more or less subdivided. Posterior row of eyes 
straight; the median eyes nearly their diameter apart, their radius or a little more 
from the anterior lateral eyes, and three-fourths their diameter from the anterior 
medians. Anterior eyes in a strongly procurved row, with the medians much the 
smaller, as usual. In the male the apophysis on the chelicera is attached near the 
middle of the anterior face and projects directly downward or a little forward of 
downward; it is smaller than in cormutus and differs also in position and form from 
that in pullulus. (PI. 3, f. 2.) The species is most readily recognized by the structure 
of the male palpus, which is represented in pl. 3, f. 3. 
Length (male), 3.2 mm. Length of femur I, 4+.8 mm.; of femur IV, 3.8 mm.; of 
tib. + pat. I, 5 mm.; of tib.-++ pat. IV, + mm. 
Type—M. C. Z. 370.

Lithyphantes mimoides sp. nov. 
Female—Carapace reddish brown or chestnut, darker on lower part of sides and 
with an obscure median longitudinal dorsal line on pars cephalica at least. Sternum 
chestnut, sometimes nearly black. Legs chestnut, with anterior tibie darker. Cheli- 
cere, labium and endites darker, almost mahogany. Abdomen in general silvery white, 
with a close network of fine brown lines; dorsum typically with four pairs of dark spots 
of which the most caudal are united; a narrow, brown hastate mark along middle, a 
brown stripe on anterior face and extending caudad along each side where it bifurcates, 
a series of oblique lines uniting the two branches in the caudal region; venter covered 
with a network of dark lines and spots. Anterior row of eyes nearly straight or 
slightly procurved. Anterior median eyes smaller than the laterals, their diameter or 
more apart and slightly farther from the laterals. Lateral eyes on each side narrowly 
separated, obviously closer to each other than in corollatus, equal. Posterior row of 
eyes slightly procurved. Posterior median eyes their diameter apart, nearly twice as 
far from the equal laterals. The species is easily separable from L. corollatus, which 
it superficially resembles, by the strongly different form of the epigynum as well as by 
the difference in eye arrangement noted above. See pl. 3, f. 4. 
Length, 7.5 mm. Length of cephalothorax, 2.9 mm. Length of tib. + pat. I, 3.4 
mm.; of tib. + pat. IV, 3.2 mm.
