abdomen is marked by a middle row of five pairs of oblique light 
spots, and the front pair of muscular spots is not conspicuous as it 
is In agils.

Male a little smaller than the female, and the same general color. 
The cephalothorax is darker than in the female, and the abdomen 
covered on the upper side with dull yellow hairs. The legs are 
darker than those of the female. The mandibles are iridescent 
green. The male palpal organ is short and wide at the base, and 
the tube is stout and with a double bend: Pl. XI. fig. 1.

Phidippus Whitmani. (Plate XI, figure 5 and Plate XII, figure 1.) 
The male of this species is very distinctly marked. It is about 
8 mm. in length, larger than most males of multformis, Pl. XIU, 
fig. 1. The cephalothorax and abdomen are red, in some individuals 
inclining to orange. There is a distinct black band across the front 
of the head behind the eyes and as wide as the largest eyes. 
There is a narrow yellow band around the front of the abdomen, 
and in some individuals two pairs of indistinct yellow spots near 
the hinder end, but in others the whole back of the abdomen is 
red without any spots. In alcohol the spots are more distinct, and 
another pair of spots often shows in front of the others. The legs 
and palpi are gray with irregular dark and light spots obscured 
by long hairs. In alcohol the femora are dark and the other 
joints have dark rings at the end. The palpal organ is long and 
narrow, the bulb extending backward the whole length of the tibia.
