was subequal to the diameter of the AME in 13, and less than the 
diameter of the AME in ten. 
Labium. Of 39 females measured : 26 have length subequal to 
width, 1 1 wider than long, and two longer than wide. Of 23 males 
measured: 19 have length subequal to width, two longer than wide, 
and two wider than long. 
Color. Female. Pattern illustrated in Figure 8. Carapace dark 
brown with the eye region darkest. Eyes outlined with black. A 
narrow pale brownish yellow median stripe beginning just behind the 
second eye row and running the length of the carapace. Broad mar- 
ginal stripes of the same color. Both the marginal stripes and the 
median one densely clothed with white hair. Marginal stripes broad- 
ening anteriorly and extending to edge of clypeus. Chelicerae dark 
reddish brown, almost black. 
Sternum brownish yellow. Endites darker reddish brown with 
distal ends brownish yellow. Proximal segments of legs brownish 
yellow without distinct contrasting markings, metatarsi and tarsi 
darker brown. 
Dorsum of abdomen with a broad dark brown median stripe from 
base to tip, with two pairs of white spots at lateral indentations of 
stripe anteriorly, and transverse chevrons clothed with white hair 
posteriorly. Brownish yellow area adjacent to brown median stripe 
on each side, thickly clothed with white hair; lateral edges of dorsum 
darker brown, mottled with tufts of white hair. Venter brownish 
yellow. 
Male. Very similar to the female in coloration. 
Diagnosis. Sosippus calif ornicus resembles S. agalenoides and S. 
michoacanus in color pattern. S. michoacanus is darker in color, how- 
ever, and both it and S. agalenoides can be separated from S. calif orni- 
cus by the form of the epigynum. (compare Figs. 27, 28 with Figs. 
29, 30 or 31, 32.) Sosippus plutonus is closest to S. calif ornicus in 
the form of the epigynum, but is a very dark, almost black species and 
smaller than S. calif ornicus (compare Fig. 8 with Fig. 5). Sosippus
