1930 ] Neiv Species of Xysticus 135 
Xysticus hamatinus Banks , Bull. U. S. nat. mus., 1910, 
p. 48. 
In his description, Keyserling fails to describe the pal- 
pus and the only figure given omits the most striking 
character. This, Mr. Banks described as “a long plate-like 
piece projecting straight across the bulb towards the top 
of the palpus.” The lower of the two apophysis usually 
found in the center of the palpus is prolonged into a slender 
piece which extends obliquely across the center; the upper 
apophysis is reduced to a small darkened, obtuse point 
which lies under the upper end of this piece. The end of 
the tube is bent almost at right angles and is probably 
one of the dark hooks figured by Keyserling. 
The tibia has the usual three processes, the upper, rest- 
ing against the tarsus, under the tutaculum, the lower a 
broad flattened piece and the middle reduced to a very 
small projection between the two. The palpus is much 
larger than is usual in the genus. 
The type of Keyserling is from Bee Spring, Ky. Mr. 
Bank’s type is from Sea Cliff, N. Y. In the M.C.Z. collec- 
tion it is found from Cohasset, Mass. (17 June, 1914, E. B. 
Bryant Coll.) south to Falls Church, Va., and west to Las 
Vegas, New Mexico.
