218 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 
separated from MF by 2.5 to 3 times the diameter of the latter, which, however, are much 
elevated above it; the eye space is yellowish brown, the tubercles and ocular quad glossy, 
black, corneous, with a few curved bristles placed along the margin of the clypeus, strongest 
at the base of the quad; front row slightly procurved, rear row greatly procurved. 
Leas: 1, 2, 4, 3, as follows: 52, 49, 42, 31.5 mm.; stout at the thighs, but gradually 
tapering to the tarsus, which is thin, as is also the metatarsus; in many adult females the 
last two joints, and frequently the last three joints, also including the patella, are glossy 
black, the thighs alone showing at the bases a bright yellow hue; in the younger specimens 
the leg is striped with brown and yellow (see Fig. 4); the whole surface is coyered with 
short hairs, yellow on the femora and dark on the other joints; femora-I are usually 
darker, and specimens will be found in which they are almost black, a peculiarity which 
extends to the third leg; surface thickly covered with bristles, and less abundantly with 
short dark spines; the palps are colored and armed like the legs, but in some specimens 
are entirely yellow; mandibles conical, dark brown, and glossy with yellowish tips. 
Aspomen: An elongated oval, narrowed or broadened according to the maturity or age 
of the individual; its width is usually about two-fifths its length, broadest about the 
middle, slightly tapering towards the apex, which overhangs the spinnerets; it also narrows 
somewhat towards the base, which is marked by two well developed conical processes, 
which project rather forwards than sideways, as in the case of Epeira. They show 
decidedly in half grown specimens, and more or less in adults not gravid, when the 
abdomen is distended with eggs; the dorsal field is marked by a broad irregular median 
band of blackish brown, flanked on either side by an irregular broken band of yellow 
spots; the median blackish brown band is marked by four to six, usually the latter, patches 
or spots of yellow, arranged symmetrically along the median line; four longitudinal brown- 
ish stripes, which are often indistinct, pass from the middle of the dorsal field along the 
folium to the apex; the surface is somewhat freely covered with short, silvery white hairs, 
and the skin is reticulated; the venter has a broad brown band, compressed towards the 
spinnerets, with eight circular yellow spots arranged symmetrically on the median line, 
and a broad ribbon of bright yellow along either margin, which passes to the base of the 
brown’ spinnerets, encircles the same in a broken band. The epigynum (Plate XVI., Figs. 
5, 5b, 5c) has a low, wide, yellow atriolum, subtriangular in form, but little separated from 
the venter; the scapus is brown, glossy, corneous, widest at the base, and curved along the 
lower side, short, terminating in a wide, notched tip, which is hollowed on either side; 
when removed from the venter, and the under part is viewed, this organ is seen to be 
quite hollow; it is covered with short, curved, black bristles. 
Mare: Plate X, Figs. 5 and 6. The male of this species is about one-fourth the size 
of the female, being 6 to 8 mm. in body length. The cephalothorax is yellowish brown, 
covered, but less densely than the female, with white and yellowish white hairs, which 
also sparsely clothe the caput, and are found within the eye space. The eyes are arranged 
nearly as in the female. The MF are about 1 to 1.5 diameter removed from the margin of 
the clypeus, and are separated from SF by a space a little greater than that which divides 
themselves. The rear eyes are on tubercles, propinquate, SF slightly the smaller. The front 
row is arranged in a nearly straight line, the rear row much procuryed. The legs are 
brownish yellow, with faintly marked annuli, and well provided with spines, bristles, and 
hairs. The abdomen is a long oval, widest at the top, where at each corner the base 
presents a slight conical process, and is marked by a cluster of long bristles. Along the 
middle of the dorsum extends a wide dentated band of brown color, interspersed with 
yellow, on either margin of which along the sides is a zigzag band of white, sprinkled 
with silver hairs, corresponding with the interrupted zigzag bands on the sides of tae 
female. The mandibles do not extend beyond the border of the eye space, and the head 
on either side projects beyond them, The humeral, cubital, and radial joints of the palp 
are yellowish white, the two last named being short and irregularly rounded, the last one 
particularly having a number of radiating bristles. The digital joint is bright brown, inter- 
mingled with yellow color, and may most readily be distinguished by three projections 
extending from the outer side, of which two are relatively long, and the third, or shorter
