J. H. Emerton — JSfexo England Attidce. 229 



One of the most common Attidiv, living on plants, especially 

 evergreen trees, all over New England. 



The colors of the male, Fig. 2^*, differ extremely from those of the 

 female. The legs are ringed as in the female, but the brown parts 

 are wider and not obscured by white hairs, while the white parts are 

 whiter. The cephalothorax is dark brown with a white stripe each 

 side under the eyes, bending toward each other behind but not con- 

 nected. The front of the head is also white and covered with long 

 white hairs, "^rhe palpi have the femur dark brown at the base and 

 white at the end. The patella and tibia are brown and the tarsus is 

 bi'own with white hairs on the upper side. The abdomen is white in 

 front and around the sides. The middle is dark brown with a few 

 yellow and greenish scales in the middle. The brown area is iisually 

 notched at the sides in four scallops and sometimes indistinctly 

 divided in four pairs of spots as in the female. 



In the female the cepalothorax is a third longer than wide and not 

 much widened across the middle. In the male the cephalothorax is 

 only slightly wider. The mandibles are vertical in both sexes and 

 but little larger in the male than in the female. 



The male palpi and the palpal organs are large in i)ro]»ortion to the 

 size of the spider. The palpal organ extends back beyond the tibia. 

 The tibial hook is very small. Fig, 2e. The tube of the palpal 

 organ has a stiff point at its side a little longer than the tube itself.

The epigynum has the front opening small and divided into two 

 directed sidewise. Fig. 2/", 



Dendryphantes montanus, new sp. 



Female 7™™ long, a little smaller than militaris, cephalothorax as 

 long as in militaris but not as wide. , Legs and mouth parts a little 

 more slender than in militaris. The markings, as far as can be 

 judged from specimens in alcohol, are like those of militaris. 



The male has the cephalothorax nearly as wide as long. PI. XVII, 

 fig. 3a. The mandibles are as long as in militaris but not as stout, 

 fig. 3b, and the palpi are as long and much stouter. The femora of 

 the palpi are thickened towards the end, as in (estivalis, and the tibia 

 and patella are very short. The palpal organ is long, and the tube 

 long and stout. Figs. Sd, 3e. The epigynum, fig. 3c, has a single 

 round opening, and a notch of various shapes, like mstivalis.
