Tlie three following genera are ant-like in general appearance. 

 They are long and narrow. The pedicel of the abdomen is long and 

 visible from above. Abdomen and cej^halothorax each with a depres- 

 sion near the middle ; legs slender. 



Synageles Sim.on. Dorsal eyes as far back as the middle of the 

 cephalothorax. Transverse dej)ression very slight. Cephalothorax 

 flattened above, the hinder half narrowing slightly backward, IS. 

 picata, page 250. 



/SaUicus Latreille, Simon. Cephalic part of cephalothorax higher 

 than the thoracic. Mandibles large. Palpi of females with tibia 

 and tarsus thickened. iS. ej^hij^j^iattis, page 249. 



Synemosyna Hentz. Very long and narrow. Depressions in 

 cephalothorax and abdomen deep. Cephalothorax and abdomen both 

 narrowed toward the pedicel. Middle eyes very large ; the others 

 all small. S. formica, page 248. 



Phidippus multiformis, new sp. 



Phidippus rufus Peckham, but not Attus rufus Hentz, nor A. castaneiis Hentz, nor 

 Phidippus ruber (Keyserling) Peckham. Keyserling has named this species Phi- 

 dippus auctus Koch in the Cambridge museum. 



The female is 8 to 9'"'" long, the male 5 to 7™™. The general color 

 of the adult female is j^ellowish brown with black and white mark- 

 ings. Around the front of the abdomen is a white band, and on the 

 back are two indistinct longitudinal black stripes in which are four 

 pairs of wdiite spots. The general brown color is produced by a 

 mixture of scales and hairs of various colors. The females are most 

 brightly colored just before reaching maturity. The general color is 

 then a bright orange, mixed with darker red and brown scales and 

 black hairs. The cephalothorax is covered with yellow scales inclin- 

 ing to red in the middle of the back. The black stripes on the 

 abdomen are more distinct and the white spots larger. PI. XVI, 

 fig. \b. The legs are pale in the middle of the joints and dark toward 

 the ends and covered with gray and black hairs. The palpi are yel- 

 low. The hairs and scales are of various shapes, the most common 

 being that of slightly flattened hairs, fig, 1/, These, with black 

 hairs, form the darker colors. The yellow and orange scales are 

 wider and less sharply pointed, fig. \h, and the white spots have 

 short and wide scales. Under the abdomen the color is light gray 

 with two parallel darker stripes. In younger spiders the black
