DESCRIPTION OF GENERA AND SPECIES. 261 



brown, with lighter patches of yellow, the caput and face yellowish brown. Sternum shield 

 shape, longer than wide, elevated in the centre, brown, with a yellow median band. The 

 labium is long, of nearly equal width throughout. The maxillie (Fig. Id) are extremely 

 long, rounded at the tip o.n the inside, and bluntly pointed on the outside, the width about 

 one-third the length. 



Eyes: Eye space wide; the ocular quad (lb) on an elevation most prominent in front; 

 rear wider than front, and about equal to sides ; MF larger than ]\1R, separated by less 

 than 1.3 diameter ; JNIR separated by nearly 2 diameters. The side eyes on a slight 

 tubercle; SR greater than SF, from which they are separated by about their diameter; the 

 space between side eyes is less than that between IMF and MR; SF are separated from MF 

 by about twice the distance between IMF. The clypeus in height about 1.5 diameter MF. 

 All the eyes are black, or upon black basal spots. The front row is slightly recurved, the 

 rear row about aligned. 



Legs : 1, 2, 4, 3 ; long, thin, armed with light, yellowish bristles, and rather sparingly 

 with long, thin spines, set upon dark pits; first pair eleven times as long as the ceplialo- 

 thorax ; color, warm yellow, with slight brown annuli at tips of joints, and the feet some- 

 what darker or blackish. The palps resemble the legs in form, color, and armature. The 

 mandibles are long, subcylindrical, the outer margin concave, bent sharply outward toward 

 the tips, where they are widely separated ; their length is about that of tlie cephalothorax ; 

 the fang (le) is long, curved, sinuated, not quite touching the niaxillse, black, or blackish 

 brown ; the base marked with a tooth on the upper surface. The mandibles are a light 

 shade of brown or dark yellow. The tips are armed around the apical margin with strong 

 black teeth ; one large tooth is placed upon the apex of the exterior fiirrow ; after a wide 

 interval there follow six smaller teeth. The interior row consists of nine to ten teeth, 

 diminishing in size toward the base. 



Abdomen : Much longer than wide, cylindrical, thickest at the base. The dorsum is 

 highly arched on the base, about the middle slopes downward, and the apical half contracts 

 into a width of about one-half that at the base, where it is somewhat rounded or trun- 

 cated ; the spinnerets are distal. The surface is clothed with delicate pubescence ; the color 

 varies from yellow to light brown, with, e.specially in alcoholic specimens, metallic, golden 

 reticulations. The dorsal folium is bounded by two longitudinal, waving lines, having about 

 three indentations from the base to the apex. In the middle is a darker longitudinal band, 

 separated more or less distinctly by a median line. The ventral pattern is a brown or dark 

 yellow band, pa.ssing from the gills to the spinnerets, with marginal bands of lighter color, 

 the whole reticulated like the dorsum and sides. Tlie epigynum (Ic) is simply a small 

 semicircular hood, without any scapus. 



Male : Length, 8 mm. ; from the tips of the outstretched mandibles, 11 mm. The legs, 

 cephalothorax, and mandibles are colored as in the female, and the abdomen has the same 

 general colors and form. The dorsal folium, however, is not so complicated. The abdomen 

 is not so thick at the base, relatively, but is more equal in length throughout, cylindrical, 

 and covered with pubescence apparently stronger than in the female. The palps are 

 extremely long (2a, 2b), the digital joint swollen into a semiglobular bulb, beyond which 

 the cymbium and alveolus much project ; the cubital joint is about one-half the length of 

 the radial. The mandibles (2a) are relatively longer than those of the female, more uni- 

 formly concave outwardly, thickened towards the tips, with long, sinuated fangs ; of the 

 teeth on the front margin of the claw furrow one is much longer and stronger than the 

 other, and one strong, curved tooth, next in size to the above, is set upon the inside, at 

 the tip. A long spur, with bifid ti]>, marks the ujiper and exterioi' part of the apex. The 

 labium is long, somewhat narrower at the rounded tip ; the maxillse, as in the female, 

 extremely long, cut ratlier more squarely at the tip, where they are widest, and thence 

 curving along the outer margin to the base, where they are even thicker than at the tip. 



Distribution : This species is widely distributed throughout the LTnited States, my 

 specimens locating it from New England, along the Atlantic Coast, southward and west- 

 ward through Pennsylvania, Ohio, AVisconsin, and again along the Pacific Coast from 

 Oregon to California. Hentz found it in North and South Carolina and Alabama ; Abbot in
