 5 — 6 mm. long, the cephalothorax 3 mm. long. The female 

 is covered with bluish gray hairs, through which can be seen indis- 

 tinct white markings on the abdomen and dark gray at the ends 

 of the joints of the legs. In alcohol the light gray color disappears, 

 and dingy gray and brown take its place on which the white and 

 dark markings show more distinctly. The male is brightly marked 

 with black and white. The cephalothorax has a pair of white stripes 

 at the sides and another pair just above the lateral eyes extending 

 its whole length, and a white middle stripe from the front middle 

 eyes as far back as the posterior eyes. The abdomen has lateral 

 and middle white stripes connected in front ; the lateral stripes are 

 broken in their hinder half into two white spots, and the middle 

 stripe is sometimes broken into spots at the end. The second, 

 third, and fourth legs are irregularly ringed with gray and white, 

 but the first pair are highly ornamented with long black hairs and 

 white spots, PI. XII, fig. 3a, 3b. The first leg has the femur black with 

 short hairs like the other legs, the patella white with a crest of 

 white hairs above and long black hairs below, the tibia black with 

 a white spot on the upper side near the end, and long black hairs 

 above and below, the metatarsus and tarsus white. The third legs 

 have no peculiar modifications of the patella or tibia. The palpi 

 have the tarsus black and the patella white. 



In marsh grass and under sticks and stones along the shore, 

 Ipswich, Mass., Long Island, New York. 



Males and females mature about August 1. In dancing before 

 the female, the male holds the front legs out sidewise with the 

 tibia nearly horizontal and the tarsus turned downward, and walking 

 on the other six legs, approaches her by short quick steps without 

 much movement from side to side until near enough to touch her 

 and then quickly retreats.
