bristle on margin above coxse I. Many small clavate bris- 
tles on cephalothorax and abdomen, spatulate hairs on 
legs arranged in rows. Quadrangle wider in front than 
behind. 
Epigynum. A shallow depression divided by a septum, 
on each side large oblique opening. The usual anterior lobe 
is large and quite remote from the other parts.

Ozyptila formosa sp. n. 
Figs. 5, 7, 17. 
$ 3 mm. long. 
Cephalothorax dark brown, median light stripe very ob- 
scure at anterior portion; abdominal markings indistinct; 
legs, I femur, patella and tibia dark brown, slightly mottled 
with light brown; II, III, IV femora light yellow at base, 
patellae and tibiae dark brown; all tarsi and metatarsi 
light yellow ; sternum, coxae and venter light without 
markings. Spines; one spine on upper side of all femora; 
I tibia 2-2, metatarsus 2-2-2, no lateral ; II tibia 2-2, meta- 
tarsus 2-2-2, 1 lateral ; all paired spines longer than diame- 
ter of joint. Quadrangle of eyes slightly narrowed pos- 
teriorly. Clavate bristles small and only ordinary bristles 
on clypeus. 
Palpus. Superior apophysis of tibia, with a slight tooth 
near base on the exterior side, prolonged into a sinuate 
spine more than half the length of the tarsus, and parallel 
with it. Inferior apophysis about half the length of the 
superior, slender and ending in slightly enlarged tip, which 
rests against a blackened lobe on the lower side of the 
palpus. The superior and inferior apophyses are separated 
by a white intermediate lobe. The palpal organ is very 
simple and has, like the typical Xysticus, a superior and 
inferior apophysis widely separated; between the two is a 
small black cusp. At the opposite side is a dark crescent- 
shaped piece. The embolus is short and rests against the 
superior apophysis. There is a slight tutaculum similar 
to Xysticus.
