PHOLCIP.l 

 Psilof/iorus californi,r sp. nov. 



Carapace, slcrnum. and legs yellow or the carapace and legs proximally of pale 

 brown casi ; the femora proximally and the patella and tibis 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 eves 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 corniiliu and differs also in position and form from 

 that in /<ullulu3. (PI. 3, f. 2.) The species is most readily recognized by the structure 

 of the male palpus, which is represented in pi. 3, f. 3. 



Length (male), 3.2 mm. Length of femur I, 4.S mm.; of femur IV, 3.S mm.; of 

 tib. -f pat. I, 5 mm.; of tib. -f- pat. IV, 4 mm. 



Type— M. C. Z. 370.

 l.illiyfilianirs mimiiiJrs sp. nov. 



h'emale — Carapace reddish brown or chestnut, darker on lower part of sides and 

 svilh an obscure median longitudinal dorsal line on pars cephalica at least. Sternum 

 chestnut, sometimes nearly black. Legs chestnut, with anterior tibiae darker. Cheli- 

 cer.T, labium and enditf> darker, almost mahogany, .'\bdomen in general silvery white, 

 with n cllr^e network of tine brown lines; dorsum typically with four pairs of dark spots 

 of which the most caudal arc 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 obli(|ue lines uniting the two branches in the caudal region; venter covered 

 »vith 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 lornllalus. equal. Posterior row of 

 eyes slightly procurved. Posterior median eyes their diameter apart, nearly twice as 

 far from the ei|ual laterals. The species is easily separable from /.. corollalus, which 

 it superficially resembles, by the strongly different form of the epigynum as well as by 

 the difference in eye arrangement noted above. See pi. 3, f. 4. 



Length, 7.5 mm. Length of cephalothorax, 2.9 mm. Length of tib. -f pat. 1, 3.4 

 mm.; of tib. -|- pal. IV, 3.2 mm.
