Peck-Jiani — Spiders of the Family Attldae, 289 



broken at the edges by three pairs of red bars, the first pair 

 near the middle, the others, less distinct, behind. There is a 

 faint yellowish band around the anterior end of the abdomen, 

 and below this and around the lower sides it is black. There 

 is a thin covering of black and white hairs over the back. The 

 falces are bright green. The palpi are dark brown with black 

 and white hairs, and the legs black with yellowish hairs. 

 We have a single female from Santa Fe, xs^ew ]VIexico. 



Phidippus calif ornicuSy sp. nov. 

 PL XXIII, figs. 3-3a. 



A handsome spider of above medium size, with red abdomen^ 

 black cephalothorax and dark legs. 



$, Length 13. Length of cephalothorax 5.5 ; width, 4.5. 



Legs 1423 ; those of the first pair longer than the body 



The cephalothorax is black with a covering of coarse brown- 

 ish hairs w^hich grow long about the front part of the head. The 

 falces are iridescent bluish-green. The abdomen is bright red 

 with two longitudinal black bands which are broken in two 

 places, behind the middle of the dorsum, by red bars. There is 

 a narrow white band, scarcely visible from above, around the 

 front and sides. Over the back is a thin growth of long brown- 

 ish hairs. The legs are very dark brown, the first and second 

 pairs being almost black. The first legs are more heavily 

 fringed than the others, the hairs being brown on the femur, 

 white on the patella, brown on the tibia (this joint is black and 

 iridescent), white on the proximal halves of the metatarsus and 

 tarsus, and brown on the distal halves. The palpus has white 

 hairs and scales on the femur, patella, and tibia. 



Calif ornicus is too large to be taken for rufus (8.5) or in- 

 solens, (9.5), both of which have the cephalothorax red, and, 

 moreover, neither of these species has been found further west 

 than Colorado. It is most like Johnsonii, which is not much 

 smaller, and is also found on the Pacific Slope. The coloration 

 is similar, although Johnsonii has the abdomen crimson rather 

 than red, with the black bands very indistinct or entirely lacking.
