942 AMERICAN SPIDERS AND THEIR SPINNINGWORK.

its hinder extremity is sometimes prolonged in a quasicaudal form. Ail the known species 
are more or less ornamented with patches, streaks, stripes, lines, or sprinklings of brilliant 
silyer, sometimes varied with black and reddish on a whitish or yellowish, or often, in life, 
a greenish colored ground; occasionally the abdomen is short, stout, or subglobular. The 
true Meta has the legs usually stronger and more freely clothed with spines, and the 
abdomen in form more subtriangular than in Argyroepeira, approaching more nearly the 
larger Linyphioid spiders. The palps of the male in Argyroepeira nearly approach in 
structure those of Tetragnatha, as well as those of Pachygnatha.*

Fremate: Total length, 7 mm.; cephalothorax, 3 mm. long, 2 mm. wide; abdomen 
5 mm. long, 3 mm. wide. 
Crrnatornorax: A long oval, truncated behind, flat upon the dorsum ; median fosse a 
deep circular pit; cephalic suture strongly marked ; corselet grooves prominent; head slightly 
depressed ; color yellow; caput smooth and rounded, but little pubescent. Along the margin 
of the corselet on either side in the adult is a row of short, stout bristles, sloping forward 
like cogs in a wheel. The corselet is of almost equal thickness throughout. The sternum is 
cordate or subtriangular, slightly longer than wide, with decided sternal cones; yellow, with 
long, blackish, bristlelike hairs. The labium has parallel sides, and an obtusely triangular 
tip; is dark brown, about half the length of the maxille, which are much longer than 
wide, the greatest width being at the tip, where it is rounded. (See Fig. 1a.) 
Eyres: The ocular quad has only the midfront eyes upon a prominence; is wider 
behind than in front; sides longer than rear. MF are separated by about one diameter, 
MR, which about equal MF in size, by a diameter and a half. The side eyes are pro- 
pinquate, SR smaller than SF, and placed behind them. MF are separated from SF 
by 1.3 their area, SR from MR by about anéqual spack, The front row is recurved, the 
rear row slightly procurved. The clypeus has the width of about one diameter MF. 
Lres: Rather long, sufficiently stout, particularly at the femora, with longitudinal rows 
of short, fine hairs. A curious tuft of long, curved hairs marks the inside of the fourth 
leg toward the front. (Fig. 1c.) These are arranged in double rows of about ten to twelve 
on each side. There are but few spines, and these long and feeble. The palps are marked 
as the legs; mandibles long, strong, conical, arched at the base, separated at tips. 
Anpomen: Cylindrical, somewhat thicker at the base, and but little wider; apical wall 
high, spinnerets placed immediately beneath; colors green, with beautiful silvery reticula- 
tions, and black longitudinal lines on the dorsal field; skin without pubescence. The 
epigynum is an open atriolum, without a scapus. 
Maun: Fig 4, side view. In general color and markings resembles the female, is 
smaller, and not so stout; body length, 4 mm.; the abdomen, which slightly overhangs the 
cephalothorax, 2.2 to 3 mm., the cephalothorax 2 mm. long. The legs are much longer than 
with the female, and, relatively, not so stout; order, 1, 2, 4, 3, as follows: 16, 13, 10, 8 mm.; 
tibia-II has no clasping spines or other special developments, and the double row of hairs 
11 have adopted substantially Cambridge’s description of this genus, Emerton having made none. 
2No. 475 of the Abbot MSS. may also refer to this species, which the drawing closely resembles. It 
is, however, somewhat uncertain; but I have no doubt at all as to No, 113,
