darker along the sides, tlie markings varying in individuals and 

 sometimes broken into irregular spots. 



The male palpi have the tarsus with a small process at the base 

 on the upper side. The tarsal hook is curved outward at the end 

 where it has two points, the distal one much the longer. Fig. 6a. 

 The mandibles of the male are turned apart from the middle, where 

 two of the teeth alon;,' their edge are much larger than the others.

The epigynum is short and wide, the outer fold in two lateral 

 lobes, with a small middle one. Fig. 6 c. 



Jackson, N. H., June 1, 1910. 



Bathyphantes intricata, new. 



3 mm. long and pale, without any markings. Cephalothorax and 

 legs yellowish and the abdomen gray. The legs long and slender, 

 the front pair 8 mm. long. The male palpi have the tibia and 

 patella short and of the usual form, without processes, but the tar- 

 sus and its appendages are extremely complicated, as best shown 

 in the figures. The tarsus has a sharp angle on the upper side and 

 a process at the base and both these are elongated into sharp, 

 curved teeth. PI. Ill, figs. 7, 7d. The tarsal hook is hard to de- 

 scribe. It has all the curves and angles found in this genus and all 

 exaggerated into teeth and ridges. 



Three Mile Island, Oct. 20, 1909. 



Diplostyla brevis. 



Like iiigrina in size and color, varying in length from 2 mm. to 

 3.5 mm. and in color from pale to dark gray, almost black. As in 

 uigrina the markings of the back of the abdomen, especially near 

 the front end, may he small gray spots in pairs on a pale ground 

 or they may be pale s])ots in a general dark gray. On the under 

 side this species is generally lighter than nigrina, having two pale 

 stripes sometimes extending the whole length or sometimes only 

 partway backward from the epigynum with the space between the 

 stripes, in some individuals, nearly as pale as the stripes them- 

 selves. 



The epigynum has the two median finger-like appendages not 

 more than half as long as in nigrina. PI. IV, fig. 1 b. The male 

 palpi have the tarsus a little shorter and less angular than in nigrina. 

 Figs. 1, la. The tarsal hook has a blunt point not widened at the 

 tip as in nigrina. Fig. 1. The palpal organ has the middle pro- 

 cess on the under side not straight as it is in nigrina, but curved
