Phidippus ferrugineus, sp. nov. (plate XXIX, jBgs. 2, 3). 



This is a large species, with two dominant colors — black and reddish brown. 

 Female. — Length, 14-15 mm. Length of abdomen, 10 mm; width of ab- 

 domen, 7mm.: height of abdomen, 6mm. Width of cephalothorax, 

 4 mm.-, height of cephalothorax, 4 mm. 

 Legs.— Relative length, 4, 1, 2, 3. Absolute length, 9.5, 9, 8.5, 10.5 mm., 



respectively. 

 Colors. — The abdomen is black beneath and on the sides, with some- 

 times faint indications of lighter spots or streaks. Above it is reddish 

 brown except in the central longitudinal region, which is occupied by a 

 black stripe extending from the anterior pair of muscle depressions to 

 the spinnerets. This stripe broadens just back of the posterior muscle 

 depressions until it is nearly 3 mm. in width, when it narrows again 

 gradually toward the tip of the abdomen. In some specimens the red 

 projects into the stripe so as to form two pairs of spots. Often these 

 spots are entirely isolated from the red of the dorsum. Occasionally a 

 spider has scarcely any indication of the stripe, being of a uniform red- 

 dish brown color above. Usually a lighter red or yellowish streak ex- 

 tends along the front border of the abdomen and runs diagonally down 

 the sides, Back of the diagonal portion of this stripe may be one or 

 two more yellowish stripes running down from the red-brown of the 

 dorsum. The cephalothorax is black beneath, on the sides, and on that 

 portion of the dorsal aspect that slopes toward the abdomen. The 

 higher portion is reddish brown above, like the abdomen. The che- 

 licera3 are iridescent green and purplish. The pedipalps and the first 

 two pairs of legs have yellowish scales scattered here and there, and 

 rings of like color near some of the joints. The presence of some long 

 whitish hairs on these appendages is also common. The second and 

 third pair of legs are almost always uniformly black, though some 

 specimens have the proximal half of the tarsus lighter. This spider 

 spends the winter under loose stones in large oval dwelling sacks of 

 closely woven silk, protected in some cases by the addition of leaves or 

 trash. I have found the species only in the vicinity of Manhattan, on 

 the summit of higher slopes of hills capped with the Permian limestone. 

 I have not been able to identify the male. ,
