markings of the abdomen are larger and the white mai'kings of the 

 hinder half larger and wider. The yellow parts are paler and the 

 joints of the legs are less darkened toward the ends. In very young, 

 just after leaving the cocoon, fig. Id, the legs are entirely pale, 

 except the claws, which are black; the cephalothorax is black with a 

 few 5'^ellow scales. The abdomen, which is very short, is black with 

 a yellow marking along the middle and around the front half. The 

 two hinder pairs of white spots are twice as wide as long, and the 

 other pair are very small. 



In alcohol the orange color disappears almost entirely. The palpi 

 remain light yellow and the colors of the legs become lighter and 

 darker shades of yellowish brown. The cephalothorax is dark brown, 

 darker on the head, and the abdomen becomes brown with the black 

 and white markings still distinct but faded. 



The colors of the male are entirely different from those of the 

 female, fig. la. The cephalothorax and legs to the end of the tibia 

 are black. The metatarsus and tarsus of all the legs are reddish brown 

 with black ends. The palpi are black with a stripe of white scales 

 on the upper side of patella, tibia and half of the tarsus. Abdomen 

 black beneath- and in the middle above. Around the front end is a 

 white stripe. The sides of the top of the abdomen are briglit orange 

 and between the orange and black areas are three pairs of white 

 spots. In the middle of the black area is a lighter stripe of yellowish 

 iridescent scales which, in some lights, can not be easily seen, and 

 may be absent altogether. 



The epigynum has a round opening in front with the sides slightly 

 darkened and toothed. The hinder notch is rounded but variable in 

 shape. PI. I, fig. le, If. 



The male palpus has the tibial hook, small and sharp. Fig, Ih, li. 



This is one of the most common Attidae on plants throughout the 

 summer. It matures in July and the males and females may be found 

 together in a bag of silk among leaves, and in the same bag the 

 female makes her cocoon of eggs, from which the young come out in 

 August and become Jialf grown before winter.

Phidippus brunneus, new sp. 



This spider closely resembles P. mxdtiformis, and I supposed it to be 

 a variety of that species. The size is the same and it has indistinctly 

 the same markings on the abdomen in some individuals. The differ-
