THE SPIDERS OF EPPING FOREST. 213
of this species, were found amongst heather near the "Robin
Hood."
Oxyptila atomaria, Panz. A single female, taken some-
where in the Forest a few years ago, is my only record, but unfor-
tunately the locality was not noted at the time of capture.
The British species not yet found in the Forest are O. trux,
Bl.; O. flexa, Cambr.; O. sanctuaria, Cambr.; and O. blackwallii,
Simon.
Genus DIAEA, Thorell,
Crab-spiders of moderate size and of brilliant colours, green
being a prevailing tint. The sexes are exceedingly dissimilar.
Diaea dorsata, Fabr. The female of this beautiful green
spider has been taken on several occasions at Loughton and
Theydon Bois.
Two other species are recorded as British, D. formosa, Bl.;
and D. devoniensis, Cambr.
Genus MISUMENA, Simon.
Large spiders of uniform pale tints. One species occurs in
Britain, and is not uncommon in the Forest.
Misumena vatia, Clerck. Found hiding amongst the
blooms of various plants, where it lies in wait for unsuspecting
insects who visit the flowers in search of honey.
Genus PISTIUS, Simon.
A single species of this genus, P. truncatus, Pallas, is found in
Britain, but it has not occurred in the Forest.
Genus THOMISUS, Walck.
In this genus the caput is peculiarly angular, and the
abdomen abruptly truncated at its posterior extremity. A single
species occurs in Britain.
Thomisus onustus, Walck. An immature male amongst
heather near the "Robin Hood" is, at present, the only record
for the Forest.
Family SALTICIDAE.
Cephalo-thorax large compared with the abdomen, very wide in front, its
sides being often nearly parallel. Eyes, eight, of the diurnal type. Four
large eyes form a transverse row upon the front of the caput, the remainder
being small, and arranged in a quadrate figure upon the upper surface of the
cephalo-thorax. Falces usually normal, but in some cases peculiarly exaggerated
in the male sex. Sternum narrow. Palpi normal, that of the male being
furnished with an apophysis upon the tibia, and occasionally upon the femur
