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 maxille (Fig. 1d) are extremely 
long, rounded at the tip on the inside, and bluntly pointed on the outside, the width about 
one-third the length. 
Eyrns: Eye space wide; the ocular quad (1b) on an elevation most prominent in front; 
rear wider than front, and about equal to sides; MF larger than MR, separated by less 
than 1.3 diameter; MR 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 MF and MR; SF are separated from MF 
by about twice the distance between MF. 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. 
Lees: 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 cephalo- 
thorax; color, warm yeilow, 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 the cephalothorax; 
the fang (le) is long, curved, sinuated, not quite touching the maxille, 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 furrow; after a wide 
interval there follow six smaller teeth. The interior row consists of nine to ten teeth, 
diminishing in size toward the base. 
AspoMeN: 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, especially 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, passing from the gills to the spinnerets, with marginal bands of lighter color, 
the whole reticulated like the dorsum and sides. The epigynum (lc) is simply a small 
semicircular hood, without any scapus. 
Mare: 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 tip, marks the upper and exterior part of the apex. The 
labium. is long, somewhat narrower at the rounded tip; the maxillz, as in the female, 
extremely long, cut rather 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. 
Disrrisution: This species is widely distributed throughout the United States, my 
specimens locating it from New England, along the Atlantic Coast, southward and west- 
ward through Pennsylvania, Ohio, Wisconsin, and again along the Pacific Coast from 
Oregon to California, Hentz found it in North and South Carolina and Alabama; Abbot in
