Peckham—Revision of the Attidce of North America. 421 
scales in the cephalic quadrangle. Abdomen similar to that of 
the male, bnt with the two central yellow lines which unite to 
form a triangular spot more conspicuous, but not meeting be¬ 
hind, with a pair of very small yellow spots between it and the 
spinners; sides and lower surface entirely clothed with dull 
white pubescence. Legs pale red-brown, i. and ii., clothed with 
yellow, iii. and iv., with yellow-white hairs. Mandibles metallic 
green, clothed with yellow hairs at the base. Palpi fringed with 
long yellow hairs.” 
We have this species from Arizona, Texas, California and 
Guadalajara, and Cambridge reported it from Chilpancingo, 
Mexico. 
Phidippus cruentus (found in Mexico), of which Mr. Cam¬ 
bridge described only the female, has the male almost exactly 
like arizonensis. The abdomen has two red bands, and white 
spots on a black ground down the middle; the third and fourth 
legs are not so hairy, and all the fringes have white hairs 
mingled with the yellow; the top of the tarsus of the palpus is 
dark marked with a white line, and the tube is much stouter 
and does not come off from a marked shoulder. The cephalo- 
thorax is not so wide, but has the same tubercles, the legs have 
the same yellow fringes, and the pencil of hairs on the femur 
of the first is present, although not quite so large. The mark¬ 
ings are like those that Cambridge figures for the female.
