Museum of Comparative Zoology, Cambridge, Mass. 
In a recent revision of the spiders in the genus Xysticus 
at the Museum of Comparative Zoology, five new species 
have been found. Two more have been figured, one for 
the first time and the other to show more definitely the 
striking features of the palpus. 
Xysticus aprilinus sp. n. (Fig. 4). 
$ 5 mm. long, cephaiothorax 2.5 mm. long, 2.5 mm. wide. 
Cephalothorax light, with a broad, brown stripe each 
side of the median light stripe, marginal markings faint 
and lacking the terminal light spots; dark spot at end of 
thoracic groove missing; abdomen much shrunken, show- 
ing no markings but occasional dark dots ; abdominal 
bristles long; legs light with a light brown stripe edged 
with faint irregular dark marks on all legs, faint broken 
band at end of femur IV ; sternum, venter and under sides 
of legs light ; spines, I tibia, 4-2, no lateral, metatarsus 5-4, 
1 lateral. Cephalothorax as long as femur I. Head very

lection. 
The two broad, brown stripes on the cephalothorax, the 
light, unspotted legs makes this distinct from any other 
species.
