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: PI. 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 multiformis, PI. XII, 

 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. 

 PL XI, tig. 5. The writer does not know the female.
