Phidippus mystaceus. 



Attus mystaceus Hentz, ? Phidnypus albomaculatus Keys., ,? P. purpuiatus Keys., P. 

 ijalathea Peckham. 



The largest of the New England Attidae, females measuring 12 to 

 15'"™ long. The female is black, covered with gray hairs and scales 

 closely enough to give the whole spider a gray color. On the abdo- 

 men are two longitudinal black stripes that do not extend quite to 

 the front end and in these stripes are four pairs of bright white spots. 

 The front end of the abdomen is crossed by a white band that ex- 

 tends back obliquely each side and at the sides of the abdomen are 

 several oblique white stripes with black edges. PI. XVI, fig. 3. 

 The hairs of the palpi and front of the head under the eyes are longer 

 and whiter than on other parts of the body. Under the abdomen is a 

 middle dark line narrowing behind, on each side of which is a light 

 gray border. At the sides of this are two wider dark bands and 

 outside of them lighter gray. Legs gray, not ringed but a little 

 darker toAvard the ends of the joints. 



In alcohol the general color becomes dark brown and later reddish 

 and all the markings are less distinct. 



The male resembles the female but is darker colored. The cepha- 

 lothorax, palpi and legs are black with a few scattered white scales 

 and hairs. Abdomen black beneath. Back of abdomen with a 

 greenish white border and a black area in the middle in which are 

 four pairs of white spots. 



The 'male palpus is large. The tarsal hook is nearly as long as the 

 tarsus and sharp and slightly curved at the tip. Fig. 3a, 35. 



The epigynum has a hard plate with two small openings in front 

 and a notch of various shapes behind. Fig. 36', 3c?. 



It lives under stones at all seasons. In winter or when moulting 

 or laying eggs it hides in a thick white bag of silk, in which the 

 cocoons are made early in the summer. The young become nearly 

 full grown before winter. Adult males are found from May to July 

 and adult females at all seasons. 



Common all over New England. Peckham has not found it in 

 Wisconsin.

Attus audax Heutz, Alius tripunctatus Hentz, Phidippus morsilans Peckham. 



A large female from Connecticut, measures lo""" long and they 

 are usually 8 to 9™". Peckham says western specimens are larger, 

 often as long as 15'"'".
