DESCRIPTION OF GENERA AND SPECIES. 203 
Frmare: Total length, 7 mm.; cephalothorax, 3.5 mm. long, 3 mm. wide, 1.5 mm. at 
the face; abdomen, 6 mm. long, 5.5 mm. wide below the shoulder humps; across the 
shoulder humps, 6.3 mm. 
CrrHALornorax: ‘Triangular ovate, widest near the base, where it is truncated, and 
sharply shelving to the crest, where the corselet is highest; thence it slopes forward again 
with considerable inclination toward the face; margins rounded; cephalic suture well 
marked; corselet grooves not distinct; fosse a semicircular depression, overcoyered by the 
cephalothorax; color yellowish brown, glossy, rather sparsely coyered with stout, gray, 
bristlelike hairs, whose bases are distinctly marked with slight rugosities; caput much 
depressed, sloping to the face, which would appear contracted except for the strong tubercles 
on which the side eyes are set. The sternum is shield shaped, and longer than wide, on 
account of the projecting apex; with sternal cones; the sides deeply indented; the centre 
covered with bristles; color yellow, with rather lighter shade in the middle. Labium sub- 
triangular, wider than long, and about half the height of maxillse, which are rounded at the 
sides and tip, and but little wider than long. Both labium and maxille yellowish brown; 
slight elevations mark the sternum opposite the eoxe. 
Eyes: Ocular quad on a high prominence, which is elevated above the side tubercles, 
and is higher behind than in front. The quad front is slightly wider than rear, and about 
equals the sides; MF separated by about or more than 1.5 diameter, and a little larger 
than MR, which are separated by about the same space. Side eyes on prominent 
tubercles; barely contingent; the front somewhat larger than the rear; SR well behind SF. 
MF are separated from SF by about 1.3 their area, and from the margin of the clypeus 
about 2 to 2.5 diameter of MF. The front row is recurved, the rear row slightly pro- 
curved, and the longer. (Fig. 3b.) . 
Leas: 1, 2, 4, 3; stout, heavily covered with gray pubescence and bristles, and with 
numerous white spines with dark bases. The front and inner sides of the metatarsi, 
particularly of the first, second, and third pairs, are marked by thickly set rows of 
yellowish spines, with brown bases, curyed toward the front and inner sides, which extend 
also to the apical half of the tibia. This hairy and spinous armature gives the legs a par- 
ticularly hirsute appearance. The color is a warm yellow, marked with narrow, dark 
brown annuli at the tips of and between the joints; palps colored and armed as the legs; 
mandibles cylindrical, not projecting beyond the clypeus. 
AxspomEn: Subglobose, arched in front and along the dorsum; the base with two 
castellated tubercles, whose summits are marked by numerous conical spurs or warts, a 
few of which appear upon the front, just below the base of the castle. The color is cre- 
taceous, mottled with blackish spots; and a folium of indistinct outlines, in the specimen 
in hand, marks the dorsal field, with wavy lines of black or blackish brown. The surface 
is covered with numerous short, gray and black bristles, which extend also to the sides of 
the tubercles and the warts thereon. The venter is a broad, blackish band, marked with 
median lines of yellow; spinnerets distal, dark brown in color; epigynum (Fig. 8c) is 
without a prolonged scapus, haying a short triangular flap, somewhat pointed, which does 
not extend beyond the posterior margin of the genital cleft. The atriolum is widened and 
arched, hairy and yellow. 
Disrrreution: Kentucky, North Carolina, and Florida. Hentz found specimens in the 
mud daub nests of Sphex cyané@a, and supposed the species to be rare; but it is probably 
well distributed throughout the Southern States. (Marx Collection.) 
Genus WAGNERIA, new. 
I propose this genus, in honor of Professor Waldemar Wagner, of Moscow, to receive 
Cambridge’s species, Epeira tauricornis. It is distinguished by a corselet high at the 
summit, descending abruptly to the truncated base; cephalic suture so plainly marked that 
the caput is sharply differenced from the corselet, is squarely truncate at the base, and 
rises thence arched to the vertex, whence it slopes to the face, which is broad. The
