chitinized; on the anterior margin is a small depression 
which obviously bears pores leading into the spermathecal 
ducts; these ducts are indistinctly seen through the chitin 
extending from the depression almost to the genital furrow 
in the midline. The spermathecae can be indistinctly seen 
in the anterior lateral parts of the epigynum. 
Holotype: Female, collected at Seattle, Wash., by Pro- 
fessor Kincaid. (Exline Coll.) 
Closest to Tegenaria calif ornica Banks, but separated by 
the much greater distance between the anterior median 
eyes, and the large chitinized area of the epigynum which is 
negligible in T. calif ornica. 
Tegenaria magnacava n. sp. (Fig. 5) 
Female: Length 11 mm. Cephalothorax light reddish 
yellow with grayish streaks on the sides, cephalic part only 
a little darker than the thoracic; cephalothorax moderately 
rounded with no great demarcation between cephalic part 
and thoracic. Chelicerae quite geniculate in front, red in 
color. Legs well clothed with hair, moderately long and 
tannish or reddish yellow. Eyes of equal size, those of pos- 
terior row somewhat procurved, widely and equally spaced. 
Eyes of anterior row almost equally spaced, but slightly 
nearer each other than those of posterior row. Abdomen 
with a light yellowish gray background and mottled and 
checked with dark gray markings. Epigynum large sur- 
rounded by a thick posterior fold of chitin and an anterior 
semicircular fold ; the cavity formed by these is large and 
deep. See fig. 
Holotype: Female, collected at Seattle, Wash., Nov. 20, 
1930. (Exline Coll.) 
Similar in size and physical structure to Tegenaria der- 
hami Scop. The epigynum is entirely different in form 
from that of any other species, consisting of a large cavity 
surrounded by chitinous folds.
