NEW AND LITTLE KNOWN SPECIES OF TEGENARIA 
(Araneida: Agelenidae) 
By Harriet Exline 
University of Washington 
Three new species of Tegenaria have been found in the 
Pacific Northwest and are described in this paper. Two 
other species, Tegenaria nana Simon and Tegenaria Cali- 
fornia Banks, are included because they are quite common 
in the Northwest, and because their original descriptions in- 
cluded no figures. The most common Tegenaria represented 
in this locality is the cosmopolitan species Tegenaria der- 
hami (Scop.), a description of which is omitted because it 
is adequately described and figured elsewhere (Emerton: 
Common Spiders, 1902, p. 96; ibid: New Eng. Spiders, 
Trans. Conn. Acad., Vol. VIII, 1889, p. 29, f. 6.). 
Notes of appreciation are expressed to Miss Elizabeth B. 
Bryant of the Museum of Comparative Zoology for identi- 
fying specimens of Tegenaria, and to Drs. Melville H. Hatch 
and Robert C. Miller of the University of Washington for 
their help and inspiration, and especially to Professor 
Trevor Kincaid for the loan of his collection of spiders.

hairy legs. Cephalothorax reddish yellow, becoming quite 
reddish on cephalic part and almost black around and in 
front of the eyes. The cephalic part is rounded, highest in

what geniculate, with prominent yellow condyles. The eyes
