Neiv Spiders from New England. 407 



Dentryphantes castaneus, (Hentz), Peckham. Revision of the Attidae 

 of North America, Trans. Wis. Acad., 1909. 



Female 6 mm. long. Cephalothorax 3 mm. The cephalothorax 

 is covered with .short gray hairs I)ut in alcohol the whole front 

 half appears black and the hinder half brown. The abdomen is 

 brown with a white stripe around the front. There are fine waving 

 black lines running irregularly lengthwise and in the middle of the 

 hinder half a middle row of indistinct herringbone markings. In 

 alcohol the markings are more distinct and there is none of the red 

 color which is so evident in the other species of Dendryphantes. 

 PI. VI, fig. 5. The legs are pale with faint brown marks across 

 the middle of the joints which are deeper colored on the patella, 

 tibia and femur of the first legs. On the under .side the legs are 

 pale, including the coxae and sternum, with no marking except on 

 the front pair. The under side of the abdomen has three black 

 .stripes from the epigynum, nearly to the spinnerets and at the sides 

 the waving black lines extend underneath. Fig. 5 a. The epigynum 

 has a short rounded notch showing nothing distinctive. 



Gloucester, Mass. in a sphagnum bog, Aug. 25, 1910. Found 

 before by Banks in the southern states from Washington to Nortli 

 Carolina. 



Sittacus striatus, new. 



Female 5 mm. long. Male 3.5 mm. Cephalothorax in both sexes 

 2 mm. long. The cephalothorax is less narrowed in front and has 

 the sides straighter than in S. palusfris. The cephalothorax has 

 three narrow light stripes. The markings of the abdomen are much 

 like those of the female Dendryphantes mililaris, the middle markings 

 only slightly larger than the others. PI. VI, figs. 6, 6 b. Neither 

 s|iecimen has the large middle light mark which is conspicuous 

 in palustris. The legs are striped lengthwise, while in pahistris 

 they are ringed crosswise, but on the under .side there are indistinct 

 rings on the femura. The general color is light yellow-brown like 

 straw, much lighter than the usual color of palustris. The male 

 palpus has a sharji process on the outside of the tibia nearly as 

 long as the rest of the joint, as in palustris, but the bulb of the 

 palpal organ is circular while in palustris it always has a depression 

 on the outer edge. Figs. 6, 6e. 



A male and female were taken in straw on a salt marsh at Plum 

 Island, Mass., June 17 and another female in a sphagnum bog at 

 Bangor, Me. June 30.
