red hairs like those on tlie cephalothorax; it has a white basal band 

 which extends on to the sides, and four indented dots. The legs are 

 dark reddish brown, with many white hairs. 

 2 . The color is much. less brilliant than in the ^ , being usually of a dull 

 brick-red hue. The abdomen, besides the white basal band, has an 

 obhque white band on each side, and two black bands on the poste- 

 rior dorsal parts; these black bands reach the apex, and curve toward 

 each other anteriorly; each has a white dot at its anterior, and one 

 at its posterior end, and a transverse white line across the middle, 

 where it is ^dest. The legs are reddish brown with black rings. 



In cardinalis, with which it might be confused, the clyj)eus is one-third 

 not one-fourth, and the lateral anterior eye is separated by one-half not two- 

 thirds of its own diameter froin the large middle eye. The second and 

 third legs in cardinalis are about equal; in rufii^> the second is plainly 

 longer than the third. 

 Habitat: United States.
