258 ENTOMOLOGICAL NEWS. [Oct., '04 



The middle area of the cephalothorax is yellow, brightest near the base. 

 In the central longitudinal line is a narrowing streak of brown running 

 back from a point between the posterior median eyes. On either side of 

 this streak is a broader stripe of brown, ending a short distance in front 

 of the posterior margin, in an enlarged portion curved slightly outward. 

 Still farther out, conforming to the outward curve of the cephalothorax, 

 is a broad stripe of brown bordered laterally by a narrow line of yellow. 

 On the extreme lateral margin is a hair-line of brown. 



The ground color of the abdomen is dark brown. There is a narrow 

 central stripe of dirty yellow and three broad transverse bands of about 

 the same color. The portion of the dorsal region not occupied by these 

 bands is punctate with yellow. The legs are yellowish brown, the former 

 color predominating in the proximal joints, the latter on the tibiae, meta- 

 tarsi and tarsi. The third and fourth pairs of legs are lighter in general 

 than the first and second pairs. ■ Scattered over the abdomen and also on 

 the front of the head and on the pedipalps are numerous stubby hairs, some 

 of them enlarged at the ends so as to be almost clavate. 



This spider is a pronounced type, but not common. Several 

 females were taken under stones near Manhattan in June. In 

 this situation they were guarding their egg sacks. 



Family SALTICID^. 

 Phidippus ierrngineus sp. nov. (Figs. 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 

 abdomen 7 mm. ; height of abdomen 6 mm. Width of cephalothorax 4 

 mm. ; height of cephalothorax 4 mm. 



Legs. — Relative length 4, i, 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 de- 

 pressions until it is nearly 3 mm. in width, when it narrows again gradu- 

 ally 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 reddish brown 

 color above. Usually a lighter red or yellowish streak extends 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.
