DESCRIPTION OF GENERA AND SPECIES. 155 



the face. Sternum cordate, inclined to rectangular, raised in the middle, with sternal cones, 

 slightly pubescent, yellow ; labium sulitriangular, though rectangular at the base ; maxillie 

 but little longer than wide, triangular at the tip, dark yellow, as is also the labium. 



Eyes: Ocular quad upon a rectangular eminence, most prominent behind; the front 

 somewhat wider than the rear, and the side about equal to the front, MF separated by 

 about two diameters; SR, which are somewhat larger and yellow in color, by al>out 1.5 

 diameter. Side eyes are on tubercles; SF somewhat larger; separated by less than a 

 radius. MF separated from SF by 1.3 the area thereof, or 1.5 the intervening space. The 

 space between MR and SR is much greater. The margin of the clypeus is removed from 

 MF by two or more diameters, the central eminence coming close up to the margin. The 

 front row is somewhat procurved ; the rear row, which is the longer, is much procurved. 



Legs: 1, 2, 4, 3; yellow, with slight annuli at the tips of the tibije; provided with 

 yellowish white bristles and hairs, and yellow spines, which are numerous underneath the 

 femora, especially of legs-I and II. The palps are yellow, and armored as the legs. The 

 mandibles are long, conical, somewhat separated at the tips, pubescent, and thickly hirsute 

 on the inner edges. 



Abdomen : A triangular ovate widest at the base, narrowing somewhat to the apex ; 

 the spinnerets distal ; dorsum arched ; the folium a simple triangular pattern, with undula- 

 ting margins ; colors light pea green, shaded with yellow to yellowish white and reddish 

 marginal and longitudinal lines; the venter a broad, yellowish brown patch, cretaceous, 

 extending upward on the sides ; the whole abdomen covered with soft yellow hairs ; the 

 spinnerets yellow, surrounded by a blackish base. The epigynum presents a semicircular 

 atriolum, brown, glossy, rugose, from which extends a short, chitinous scapus, like the 

 bowl of a spoon. 



Male: Fig. 8, 8a; 5 mm. long. In color and markings quite similar to the female. 

 The annuli of the legs appear to be darker; tibia-II is curved, and thickened at the 

 middle and toward the base; provided from the middle to the apex with a series of strong 

 dark brown spines about seven in number, of wliich one underneath is much longer, 

 having nearly the length of half the joint, and placed upon an elevated base. Under- 

 neath the femora is a row of six or more acute, brown, erect spines. The humeral joint of 

 the palps is as long as or longer than the three terminal joints, of wliieh the cubital is 

 globose, armed with long spines ; the radial is bilabed ; the digital is rounded, corneous, 

 yellowish brown, the embolus being wide, bifid, or strongly notched at the tip, presenting 

 at once a prominent characteristic. The legs are stout at the femora, but much diminished 

 in size at the mettitarsus and tarsus. 



Distribution : I have from ;Mr. Thomas Gentry one female in a collection from 

 North Carolina and Georgia. Hentz described it from Alabama, Emerton from New 

 England, and Dr. Marx has examples from Washington, D. C, Florida, Savannah, Ga., 

 New York, Columbus, and Texas. It is thus distributed along the entire Atlantic Coast, 

 and probably throughout all the Gulf States as far as Texas. Its western distribution has 

 not been determined, though it will probably be found as far west as the American Plains.

Female: Total length, 16 mm.; abdomen, 9 mm. long, 7 mm. wide; cephalothorax, 

 7 mm. long, 5 mm. wide; width of face, 2 mm. The general colors are for the abdomen 

 yellow, with black stripes and spots ; cephalothorax, orange red ; legs, orange and black. 



Cephalothorax : Corselet rounded, high at the centre ; head at the fosse elevated and 

 sloping to the front, with little decrease of width ; color brown, intermingled with orange ; 

 in one species this color is dark orange brown; skin glossy, and heavily clothed on the 

 sides and head with long gray bristles. Sternum cordate, dark orange brown, covered 

 along the margins with white bristles, higher in the centre, and about as wide as long;
