Supplement to the New England Spiders. 183 



The length is about 4 mm., the sexes differing little in size. The 

 cephalothorax and abdomen are about equal in length. The cephalo- 

 lliorax is wide in front ; about two-thirds as wide as it is at the widest 

 part, and the rows of eyes are almost straight, the upper row only 

 slightly longer than the lower. The palpi of the female are as long as 

 the cephalothorax, and those of the male longer. The maxilla? have 

 the ends straight and nearly parallel, as in Enoplognatha marmorata, 

 not oblique as in Steaioda borealis. The sternum is as wide as long, 

 widest between the first and second legs and slightly pointed behind. 

 The colors are dull brown and gray, without any markings. The ce- 

 phalothorax is smooth andshining and darkened a littletoward thehead. 

 The legs are brown like the cephalothorax, darkened toward the tips 

 and covered with fine hairs. The abdomen is gray, generally lighter 

 than the cephalothorax, and covered with dark gray hairs. The 

 epigynum has a characteristic pear-shaped piece in front, PI. 1, 

 fig. lc, but in some individuals this piece is oblong, PI. 1, fig. Id. 

 The male palpi are stout and three-fourths as long as the rest 

 of the spider. The tibia and patella are both short and together 

 equal in length to the tarsus. The tibia is a little narrowed at the 

 base and widened at the end around the base of the tarsus on the 

 outer side. The tarsus is narrow, only partly covering the palpal 

 organ. Near the tip it has a notch on the upper side, and two 

 curved stiff hairs, PI. I, fig. 1 a. 



Pedanostethus pumilus, new. (Plate I, figures 2, 2 a.) 



In the maple swamp at Clarendon Hills, south of Boston, three 

 males have been found of this small species. It is 2.5 mm. long, 

 colored like very light individuals of riparius, and resembling it in 

 every respect except in the palpi. These are proportionally shorter 

 than in riparius. being not much longer than the cephalothorax. The 

 tibia is more contracted at the base than in riparius. and the tarsus 

 is shorter, rounder and thicker. The notch near the tip is wider 

 and there are no special hairs. The female is the same size and 

 color as the male. The epigynum is short like that of riparius but 

 has the front piece wider than long instead of pear shaped fig. 2a. 

 One male also found near the Carter notch, White Mountains, 

 Aug., 1906, and another at Three-mile Island, Lake Winnipesaukee. 



Pedanostethus spiniferus, new. (Plate I, figures 3, 3 a.) 



The male is 2.5 mm. long, and pale like pumilus, and resembles 

 it except that the lateral eyes of the upper row are a little farther 

 back. The palpi have the tibia shaped much as in riparius, not
