$Philodromus lineatus.$--The female of this species is a little larger
than _ornatus_, the brown markings are lighter, and, in life or when
freshly killed, purplish in the lighter parts. The markings are less
distinct than in _ornatus_, the brown and white running into each other.
The abdomen has a brown band each side, often broken into several spots,
and a brown band in the middle extending back half its length, behind
which are several lighter marks (figs. 106, 107). Between these are
several oblique lighter markings and rows of spots. The legs are light
gray, darker toward the ends of the joints.
[Illustration: FIGS. 108, 109, 110. Philodromus pictus.--110, adult
female. 109, male without the legs. 108, markings of the abdomen of a
young female. All enlarged six times.]
$Philodromus pictus.$--Female about one-fifth of an inch long, the
abdomen nearly twice as long as the thorax, with the widest part across
the middle farther forward than in most species (fig. 110). Legs and
palpi pale yellow with fine brown spots. Thorax light yellow in the
middle and reddish brown at the sides, covered with fine spots. Abdomen
dull red at the sides and bright yellow in the middle, with a dark mark
in the middle of the front half and two dark marks behind it on the
hinder half. The eyes are surrounded by distinct light rings. In some
specimens, usually immature, the abdomen has a more distinct yellow and
red pattern (fig. 108). The male (fig. 109) has the thorax and legs
darker and the abdomen less bright red and yellow than the female,
sometimes gray and iridescent.

$Ebo latithorax.$--In color and general appearance this resembles
Philodromus, but is at once distinguished by the length Of the second
legs, which are more than twice as long as any of the others (fig. 111).
The thorax is wider than long, and the abdomen is wider than in
Philodromus. The head is narrow and rounded in front. The front middle
eyes are largest and farthest forward. The colors are gray and white,
with black spots in the darker parts, as in Philodromus. The length is
not much over an eighth of an inch and the length of the longest legs
quarter of an inch.

six times. 113, left side of the abdomen.]
