$Epeira parvula.$--A common spider all over the country, with the
abdomen wide in front and bluntly pointed behind, gray and brown colors
and a great variety of markings. The length is quarter to three-eighths
of an inch, with the abdomen two-thirds as long and as wide across the
front. The abdomen is as high behind as it is in front, and the pointed
end is sometimes turned a little upward, as it is in _conica_. The front
of the head is narrow, not more than half as wide as the back of the
thorax. The front legs are half longer than the body. The cephalothorax
is gray, darker at the sides, and sometimes with a few black spots. The
legs are irregularly marked with rings and spots, and the femora are
dark toward the end. The abdomen is commonly gray, with a tapering
scalloped middle stripe and a distinct dark middle spot and two large
light spots at the front end (fig. 416). Sometimes there is a middle
narrow dark stripe the whole length of the abdomen (fig. 418), and
sometimes all the middle is white or light yellow. The males have the
head a little narrower and more pointed, the legs longer, and the second
tibia slightly thickened, but not curved. The webs are in low bushes.

$Epeira stellata.$--A brown spider, a quarter to a third of an inch long
and nearly as broad, with pointed humps around the abdomen. The
cephalothorax is wide in front, and the lateral eyes are on the outer
sharp corners. The legs are short and usually drawn up and partly
concealed under the abdomen. The abdomen has a sharp point in front
that extends over the cephalothorax as far as the base of the first
legs, and a large point behind, with a smaller one under it. At the
sides are five pairs of points, and over the first of these another pair
a little higher on the back. The cephalothorax is brown, lighter in the
middle and darker at the sides, and covered with short gray hairs. The
abdomen is marked with lighter and darker spots of brown, the front part
generally dark with a very light middle spot, and the hinder half
showing traces of the usual middle stripe of Epeira. The legs have dark
rings at the ends and middle of the joints. It lives among low bushes a
foot or two from the ground all over the country. This spider, as well
as several other species, often leaves a web unfinished with the inner
spiral still covering a large part of it, as in fig. 420.
