New Species of Xysticus 
139 
legs, I tibia 4-3, no lateral, metatarsus, 4-4, 2 lateral; 
sternum light with many small dark dots. Cephalothorax 
longer than I femur. 
The epigynum is large and dark. 
1 $ holotype, 1 $ allotype; Mass.; Ipswich on beach, 
14 June, 1914. E. B. Bryant Collection. 
This pair was found with the cocoon at the head of the 
beach under trash. It was first identified as a small X. 
stomachosus but closer examination shows that it is a 
different species. In X. stomachosus the spins on tibia I 
are 7-5, metatarsus 5-5. And the palpus and epigynum are 
quite different. 
Xysticus vernalis sp. n. (Figs. 13, 15). 
8 3.5 mm. 
Cephalothorax dark mottled brown, with a broad median 
light stripe shaded with light brown at the anterior end, 
and a distinct dark spot at the end of the thoracic groove ; 
abdomen with the characteristic markings of the genus, a 
pair of oblique lateral marks at the basal end and three 
pairs of transverse marks, connected by a median spot; 
sternum and venter light with many dark spots; legs 
brown, showing a light line bordered with dark on femur; 
patella and tibia ; tibia and metatarsus lighter than femur ; 
anterior tarsi light; spines, I few scattered on upper side 
of femur, tibia 4-4, two middle pair longer than diameter 
of joint, 3 lateral, metatarsus, 3-3, the two middle pair 
longer than diameter of the joint, 2 lateral. Cephalothorax 
as long as femur I. 
Palpus. The upper process of tibia ends in a short, 
obtuse recurved spine, the middle process a blunt spatulate 
lobe and the lower process an inconspicuous knob bearing 
three long bristles. Three long bristles on the inner side 
of the tibia. In the palpal organ the upper apophysis is 
large, dark and bent downward, the lower is slender, dark 
and pointed, the two are separated by a clear white spatu- 
late lobe. Below the lower process is a long slender fila- 
ment lighter in color than the two median, which extends 
up and reaches the beginning of the bulb. The tutaculum 
is small and is edged with short curved hairs.
