with white; there is a 



basal band which extends 



back on the sides, a large 



central triangular spot, 



and farther back on the 



sides there are two pairs of bars. The tibiae of the first legs 



are heavily fringed. 



This is a Southern species occurring throughout the Gulf States. 



Phidippus whitmanii (P. whit-man'i-i).— The body in this 

 species is almost entirely red above. In the male the cephalothorax 

 is red except for a black hairless region extending from the first 

 to the second row of eyes; and in the female a light band comes 

 up from between the anterior median eyes, nearly crossing the 

 black hairless region. The abdomen is red with a more or less 

 distinct white band on the base and sides, and sometimes there 

 are two pairs of white bars on the posterior part. 



This is a Northern species; it has been taken from New Eng- 

 land to Wisconsin.
