The cephalothorax is reddish, covered with yellowish hairs, 
with long black hairs around the eyes and long white hairs grow¬ 
ing thick on the clypeus. The falces are dark reddish-brown 
with slight iridescence. The abdomen is covered with tawny- 
gray hairs and has a whitish band at the base and a pair of 
white spots on the middle of the back. The legs and palpi 
are bright-reddish brown with white scales and hairs. 
In shape and general color princeps is so much like Putnamii 
that very probably Mr. Banks is right in making it the female 
of that species. They have not, however, been found in the 
same locality, princeps having been taken but once, and then in 
Pennsylvania, while Putnamii (of which gracilis K. is a syn¬ 
onym) is reported from Kentucky, Iowa and Missouri. 
Mr. Banks says, in a letter of February 2nd, 1907, that the 
spiders he listed as Philseus princeps in 1892 are males of 
clarus.

This is a medium sized species of dark brown ground color, 
with the pattern in white, and many long gray hairs which give 
it a hoary appearance. The clypeus is covered with long white 
hairs passing into white bands which entirely cover the
