DESCRIPTION OF GENERA AND SPECIES. 277 



with green or olive, and orcasional patches of purple. The whole surface is reticulateil, 

 and covered with yellowish hairs; the venter has a yellowish patch flanked with hlackish 

 brown on either side, which encompasses the spinnerets and cribellum (fie), which are a 

 dull yellowish color; the epigynum (Fig. 6f) is a simple, wide, arched atriolum, without a 

 scapus, slightly projecting over the genital cleft. 



Male : (Fig. 7.) Resembles the female in general structure and coloring, but is smaller, 

 being about 3 mm. in length. The abdomen presents the same lumpy appearance, and is 

 heavily covered with hairs. The palp (Fig. 7a) is peculiar in its conformation, the digital 

 bulb being very long, tlie cymbium canoe shaped, covered closely with hairs. 



Distribution: I have collected this species at various points from New England along 

 the Atlantic Coast southward ; in New York, Pennsylvania, and Ohio. I have specimens 

 as far to the northwest as Wisconsin (Professor Peckham), and Dr. Marx has specimens from 

 Virginia, Maryland, and the District of Columbia. It will probably be found to inhabit 

 the entire middle zone of the United States. It appears to prefer mountainous or hilly 

 regions, although not confined thereto. A favorite dwelling i>lace is in or near pine woods. 



By some oversight, which neither author nor i^rinter can exjjlain, the copy of the fol- 

 lowing species was lost, and omitted from its proper place. The error was not discovered 

 until the appropriate signature had been iirinted, and a description is inserted here.

Female: Total length, 7 mm.; cepbalothorax, 2.2 mm. long, 1 mm. broad ; abdomen, 

 5 mm. long, 2.2 mm. broad, diminishing to about 1 mm. The cephalothorax is a rounded 

 oval ; color dark brown. The legs and palps yellow, with brown median and apical annuli. 

 The abdomen has a grayish hue, with tinges of yellow ; is widest at the base, where it is 

 somewhat arched, and diminishes from about the middle into an extended caudal part, 

 which projects beyond the spinnerets nearly one-half the length of the abdomen. The 

 spinnerets are placed well beneath, at the apex of the subconical venter. 



Male: (Fig. 8.) Total length, 4.5 mm. The cephalothorax is a rounded oval, almost 

 circular, slightly truncate at the base ; color reddish brown, with dark stripes passing from 

 the fosse to the margin ; fosse a circular depression ; caput slightly depressed, of darker 

 color than the cephalothorax ; face sufficiently wide. The ocular quad is somewhat longer 

 than broad, slightly nari-ower behind ; MF larger than SF, and separated by about one 

 diameter; space between MF and SF but little larger than that between MF; side eyes on 

 tubercles; propincjuate, about equal in size; front row recurved, rear slightly procurved. 



The Legs are 1, 2, 4, 3 ; yellow, with broad brown annuli on the femora, which are 

 sufficiently stout, and apical and median annuli on the other joints. They are well pro- 

 vided with stout spines, especially on the tibia of leg-I and leg-II, the latter also slightly 

 curved inward. The abdomen, as in the female, is a grayish yellow, mottled with black. 

 The spinnerets are placed about the middle of the venter, and the apex of the abdomen 

 projecting beyond into a caudal part (8a). The palp (8b) is comparatively short, but the 

 digit large, subglobular, terminal bulb brown, cymbium yellow, covered with hairs. The 

 radial joint is short, compressed, scarcely more than half the length of the cubital joint, 

 which is yellow, and has projecting from it a long, brown spine, slightly curved towards 

 the point. The position from which Fig. 8b was drawn does not show the true relative 

 proportion of the radial and cubital joints. 



Distribution : A female was taken by Hentz in Alabama ; Dr. Marx collected a male 

 in the District of Columbia, and the description of Keyserling is from a female specimen 

 collected in New Granada, South America. This indicates distribution from the northern 

 belt of Southern United States to the northern belt of South American States.
