DESCRIPTION OF GENERA AND SPECIKS. KM 



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 tho 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 portulre. 



DISTRIBUTION : 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.

MALE: 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. Gb) cordate, longer than broad, yellowish brown color. 

 I ,iil >i inn, tip triangular, confpressed at the base ; maxilhe somewhat longer than wide, 

 obtusely triangular at tip. 



EVES: 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 1.3 their area, or nearly twice their 

 intervening space ; front row recurved, the longer rear row slightly procurved ; clypeus about 

 two diameters MF in height. 



LEGS: 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. 



ABDOMEN: 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. 



DISTRIBUTION: Crescent City, Fla. The female of this species has not been taken.

FKMALE: 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. 



CEI-IIALOTHORAX : 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 inaxillii*, 

 which are gibbous, somewhat longer than wide, yellow, with a few liristlelike hairs thereon.
