DESCRIPTION OF GENERA AND SPECIES. 165 
and are tufted at the base, which well overhangs the cephalothorax. The ventral pattern 
is a broad blackish band, with lighter hues in the middle, which encompasses the spin- 
nerets, which are of lighter color, and decidedly overhung by the rounded apical wall. The 
epigynum (Fig. 5a) has a short subtriangular scapus, which extends barely beyond the 
genital cleft, and is flanked on either side by a slight bowl shaped projection apparently 
marking the outer walls of the portulz. : 
Disrripution: District of Columbia; Utah. I have seen but two specimens, which are 
in Dr. Marx’s collection, but the habitat of these indicates a wide distribution from the 
Atlantic Coast to the Rocky Mountains.

Mare: Total length, 4 mm.; cephalothorax, about 2 mm. long, 1.5 mm. broad; abdo- 
men, about 2.3 mm. long, 1.4 mm. broad. The color is a bright yellow to orange, with a 
lateral longitudinal band of yellow on the caput, and lateral bands along the cephalic 
grooves; fosse a deep longitudinal cleft; cephalic suture sufficiently distinct; slightly 
pubescent. The sternum (Fig. 6b) cordate, longer than broad, yellowish brown color. 
Labium, tip triangular, compressed at the base; maxille somewhat longer than wide, 
obtusely triangular at tip. 
Eyres: Ocular quad on a rounded elevation, dark brown in color, the eyes themselves 
black. The quad wider in front than rear, the sides longer than either; eyes subequal; 
MF separated by 1.5 diameter, MR by about 1. Side eyes on slight tubercles, contingent, 
about equal in size. MF removed from SF by about 1.8 their area, or nearly twice their 
intervening space; front row recurved, the longer rear row slightly procurved; clypeus about 
two diameters MF in height. 
Leas: 1, 2, 4, 3; yellow or reddish brown, well armored with long brownish spines; 
tibia-II without any special thickening or clasping armature, except a few additional 
ordinary spines towards the tip, which are also found upon tibia-I. The palpal digit is 
represented at Fig. 6c. 
AxspomEn: A long oval, rounded at the base and apex, of about equal width through- 
out; colors yellow, with a silvery gloss. A light folium, almost obliterated in alcohol, 
passes along near the distinctly marked muscular indentations, and on the apical part of 
the dorsum are two black longitudinal patches, passing to the apex. The surface is 
pubescent. The ventral pattern is a black or blackish brown band, which encompasses the 
spinnerets, of like color, and which are somewhat overhung by the abdomen. The entire 
skin of this spider is glossy. 
Disrripurion: Crescent City, Fla. The female of this species has not been taken.

Femare: Total length, 5 mm.; cephalothorax, 2.5 mm. long, 1.3 mm. wide; abdomen, 
4 mm. long, 3 mm. wide. General colors of fore part of body uniform yellow; abdomen 
cretaceous white, with a black folium. 
CrpHALorHoRAXx; Cordate, high in the middle, sloping backward to the base of the 
corselet; the fosse a deep conical pit; corselet grooves tolerably distinct; cephalic suture 
distinct; caput narrow at base, rounded, smooth, but much depressed to the wide face. 
Sternum shield shape, yellow, slightly pubescent, flat in the middle; skin glossy; only a few 
whitish-yellow bristlelike hairs; labium subtriangular,*about half the height of maxille, 
which are gibbous, somewhat longer than wide, yellow, with,a few bristlelike hairs thereon.
