Spiders -- United States
$Epeira verrucosa.$--Common in the South and as far north as Long
Island, N.Y. The body is about a quarter of an inch long. The abdomen is
narrow behind but not pointed, and in front nearly as wide as long. The
middle is nearly covered by a triangular light spot,--white, yellow, or
pink in different spiders,--surrounded by a darker color of various
shades of brown or gray. The cephalothorax is yellow or light gray, with
sometimes some darker spots in the middle. The legs are colored like the
thorax, with darker rings at the ends of the joints and in the middle of
the first and second femora. The spines are slender and colored like the
hairs. The abdomen has a prominent tubercle behind, at the end of the
light spot, and under it in the middle line two others. At the sides
near the posterior end are two pairs of tubercles, and sometimes two
other pairs farther forward, and two at the corners of the light spot.
The colors of the under side are as variable as those above,--sometimes
light without distinct markings, and sometimes almost black at the
sides, on the sternum, and around the spinnerets. The epigynum (fig.
422) has a slender pointed finger reaching halfway to the spinnerets.
The male (fig. 423) has the head narrower than the female, and the
abdomen as small as the cephalothorax. The legs are longer and more
slender, with the metatarsus of the second pair curved inward, and a
long forked spine on the inside of the tibia of the same legs.

with one front leg to show its great length. 425, female with the legs
of one side drawn up in a natural position, showing the spots. 426,
female with four large spots on the back. 427, under side. All enlarged
four times.]
$Larinia directa.$--This resembles a much elongated _Epeira pratensis_
(p. 167). It is about as long as _pratensis_, a quarter to a third of an
inch, but very slender,--not much more than a quarter as wide as long
(fig. 425). The general color is yellowish but pale and translucent,
marked with very distinct black spots. The spots are usually in six
pairs on the abdomen, sometimes so small as to be hardly visible,
sometimes so large as to be the most distinct part of the spider. In
some individuals there is a row of black spots on the upper side of each
leg, so that when these are drawn up over the back hardly anything is
visible except the spots. In some individuals the first and third pairs
of spots on the abdomen are very large and the others very small (fig.
426). The sternum is nearly twice as long as wide, with the sides of the
front half parallel. It is darker at the sides. On the under side of the
abdomen are two parallel dark stripes. In the male (fig. 424) the front
legs are nearly three times the length of the body, but neither the
first nor the second pair is curved or thickened. It is found in South
Carolina, Georgia, and Alabama.
