THE SPIDERS OF EPPING FOREST.
By FRANK P. SMITH.
(Continued from page 60).
(With Plates IX. and X.)
Family ANYPHAENIDAE.
[Drassidae, Cambr, List, ad partem.]
This family is very closely allied to the Clubionidae, but the single genus
represented in Britain may be easily distinguished from that family by the tube-
tracheal opening being placed not immediately in front of the spinners, but in a
conspicuous transverse depression about half-way between the genital aperture
and the posterior extremity of the abdomen.
Genus ANYPHAENA, Sund.
Spiders of moderate size, usually with distinct blackish
markings upon the pale abdomen. The males are often much
more darkly coloured than the females. A single species occurs
in Britain.
Anyphaena accentuata, Walck. Commonly beaten from
trees in many parts of the forest.
Family SPARASSIDAE.
Cephalo-thorax longer than broad, strongly constricted at the caput. Eyes
8, almost homogeneous (of the diurnal type), rather small, not greatly unequal in
size, anterior row recurved, posterior row unusually procurved. Clypeus narrow.
Labium short, almost semicircular. Maxillae rather straight, never much inclined
towards the labium. Legs, second pair shorter than fourth pair. Spines present
and fairly strong. Claw tuft and Scopula present. Tarsal claws, 2.
The Sparassidae are spiders intermediate in characteristics
between the Clubionidae and the Philodromidae. They
spin no snare. One genus is found, but rarely, in Britain.
Genus SPARASSUS, Walck.
[Micrommata, Cambr. List.]
Spiders of rather large size and brilliant colours which have
many structural affinities with the Clubionidae, but in their habits
remind one more strongly of the Philodromidae. One rare and
beautiful species, S. virescens, Clk, has occurred in Britain, but
not in Epping Forest.
Family PHILODROMIDAE.
[Thomisidae, Cambr. List, ad partem Philodrominae. ]
Cephalo-thorax short and broad, strongly constricted in the region of the
caput, and obtuse and rounded in front. Eyes eight, of the diurnal type, not
greatly unequal in size, arranged in two recurved rows, the whole group describing
a figure of a more or less crescent-like form. Legs; relative length varies in
different species. Those of the first and second pairs are always somewhat
o
