DESCRIPTION OF GENERA AND SPECIES. 203 



Female: 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. 



Cephalothorax: 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, overcovered by the 

 cephalothorax; color yellowish brown, glossy, rather sparsely covered with stout, gray, 

 bristlelil^e hairs, whose bases are distinctly marked witli 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 maxillre, which are rounded at the 

 sides and tip, and but little wider than long. Both labium and maxilLt; yellowish brown; 

 slight elevations mark the sternum opposite the coxa;. 



Eyes: Ocular ciuad on a high prominence, which is elevated above the side tubercles, 

 and is higher behind than in front. Tlie 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 tlie longer. (Fig. 3b.) 



Legs: 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, curved 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. 



Abdomen: 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 browu. 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, having 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 }'ellow. 



Distribution : Kentucky, North Carolina, and Florida. Hentz found specimens in the 

 mud daub nests of Sphex cyanea, and supposed the species to be rare ; but it is j>robably 

 well distributed throughout the Southern States. (Marx Collection.) 



Genus WAGNERTA, new. 



1 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
