OF WASHINGTON. 95 
Amcularia californica n. sp. 
Cephalothorax densely clothed with yellowish-gray hair, rather paler 
on sides and brighter in the middle; on anterior margin is a fringe over- 
hanging the mandibles of long, pale gray hairs with tawny tips; eye tubercle 
with some long, partly recurved, bristles on middle, their bases tawny, 
and their tips pale. The mandibles are densely clothed above, with 
yellowish-gray appressed hair, and long, procurved bristles, whose bases 
are tawny, and tips pale. Sternum and coxae black, with short fine 
grayish hair, and long, erect, partly tawny bristles. Legs densely clothed 
with yellowish-gray hair, and long, procurved bristles, except above on 
the femora, where there are only a few bristles near tip; the under sides 
of the legs are darker than upper side; and there is a dense black scopula 
beneath metatarsi and tarsi; there are two or three spines beneath on 
metatarsus iv toward base. Abdomen clothed above with fine dark 
brown hair, and many long, recurved bristles of a tawny color with pale 
tips; venter black-haired, and with long tawny bristles, especially notice- 
able on the posterior sides. Maxillae and fang-grooves with long tawny 
bristles. 
Length of cephalothorax, 28 mm.; width 16 mm. 
Several specimens from the vicinity of San Diego, California. 
Cybceus minutus n. sp. 
Entirely dull yellowish, the cephalothorax and legs rather brighter 
than the abdomen; eyes on black spots. Cephalothorax not very slender ; 
posterior eye-row a trifle recurved, P. M. E. more than diameter apart, 
and scarcely farther from equal P. S. E., anterior eye-row almost recurved; 
A. M. E. small, and about diameter apart, and closer to larger A. S. E., 
S. E. separate by radius; quadrangle of M. E. much narrower in front. 
Mandibles not strongly geniculate. Legs of moderate length, 4-4 spines 
under tibiae i and ii; sternum rather broad; metatarsi i not scopulate. 
Abdomen short and broad; epigynum reddish, swollen, showing beneath 
a cavity in each posterior side. 
Length 3.5 mm. 
One female from Olympia, Washington. Distinguished by 
small size, and pale color. 
Argyrodes pluto n. sp. 
Deep jet black, except a few glittering patches of yellowish near summit 
of abdomen; an oblique spot each side, two transverse dots above before 
apex, and a semicircle partly around apex. Abdomen higher than long, 
not projecting beyond spinnerets, but very high directly over spinnerets 
and ending in a rather sharp point, the posterior margin (seen from side) 
and the dorsal margin slightly convex. The abdomen (seen from above) 
is rather broad in middle, more so than in most species. The first legs 
are long, but scarcely as long proportionately as in A. trigonum. 
Length 4 mm.; abdomen high, 2,8 mm.* tibia i, 2 mm.
