170 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 
Leos: 1, 2, 4, 3; stout, yellow to orange yellow, with brown annuli at tips of joints; 
well provided with bristles and hairs, rather sparsely with stout spines; palps yellowish 
brown, armed as legs; mandibles conical, little divergent at tips, and, like the face, some- 
what glossy. : 
AspomEN: Globular ovate thickest and widest at the base, arched on dorsum, tapering 
to distal spinnerets; in gravid females the width is as great as the length; surface retic- 
ulated; dorsal field without a folium, but with three or four circular longitudinal patches 
in the median line; an irregular band of color traverses the margin; a deeper color marks 
the side; the apical half of the dorsum is sometimes marked by median lines of yellow, 
and has several black spots on either side tapering V-shape to the spinnerets. Venter ~ 
pattern a triangular patch of yellow, marked with six or eight circular spots symmetrically 
arranged on either side of the median line. Spinnerets brown; epigynum (Figs. 3a, 3b, 3c) 
has a tolerably long, yellow, curved scapus somewhat wrinkled, of nearly equal length 
throughout, slightly tapering and rounded at the tip. The parmula is a thin, elevated plate, 
scrolled at the top, placed between it and the spinnerets; this is yellow at the base, brown 
and glossy at the apex and edges, not quite as long as the scapus. 
Mate: Figs. 5, 5a. The males of this species appear to be rather scarce; at least it 
has proyed so in my collecting. They are colored and marked substantially like the 
female. Underneath femur-I is a row of four spines, which appear to be smaller in femur-IT; 
tibia-II is not thickened at the apex, but slightly curved, with a row of four strong 
rounded spines on the apical half; digital bulb globular; radial joint with a strong curved 
brown spur; cubital joint about the same length as radial; mandibles relatively longer and 
slighter than in female; the first two femora rather darker than corresponding joints of 
female. 
Disrripution: Throughout the Eastern and Middle United States, having been collected 
in New England, New York, Pennsylvania, Maryland, District of Columbia, Virginia, 
Georgia, North and South Carolina, Alabama, Florida, Tennessee, and as far to the north 
and west as Wisconsin. I have no specimens from the Pacific Coast.

Femate: Total length, 5 mm.; abdomen, 4 mm. long, 3 mm. wide; cephalothorax, 
2 mm. long, 1.5 mm. wide. The general colors are yellow and brown for the fore part, and 
yellow and gray for the abdomen. The abdomen is placed so nearly at right angles to the 
plane of the cephalothorax as much to shorten the apparent total length. 
CerHALoTHORAX: Corselet rounded at sides, truncated behind, elevated at centre, the 
grooves indistinct, cephalic suture well marked; color yellow, with sometimes streaks of 
1 No. 875 of Abbot’s MSS. drawings is undoubtedly Epeira globosa Keyserling, and the drawing cor- 
responds well with Walckenaer’s description of Epeira Pegnia. Walckenaer makes two varieties of the 
species. Abbot’s No. 484 seems not a good variety, but rather to be a Theridioid spider., His variety B is 
Abbot’s No. 375, a female. Abbot’s No. 389 (Var. B, Walckenaer) is an immature male. Abbot’s No. 555 is 
also a remarkably good drawing of this species, but I have not been able to find it referred to in Walck- 
enaer’s descriptions. : 
2 This, according to Abbot’s drawings, appears to be the same species as the above—a female.
