58 THE SPIDERS OF EPPING FOREST.
localities under loose bark, but the greater part of the specimens
taken are immature.
Clubiona compta, C. L. Koch. —Widespread, but appar-
ently not common.
Clubiona pallidula, Clerck.—Under loose bark, especially
that upon wooden fences. Fairly common in all parts of the
district.
Clubiona brevipes, Bl.—Occasionally beaten from horn-
beams, oaks, etc.
Clubiona diversa, Cb.—A single female, taken July 1902.
See Essex Naturalist, Vol. xiii., p. 22.
The following British species of Clubiona have not been taken
in the Forest up to the present:—C. lutescens, Westr., C. neglecta,.
Cb., C. holosericea, De Geer., C. subtilis, L. Koch, C. trivialis, L.
Koch, C. coerulescens, L. Koch, C. formosa, Templ, (a doubtful
species).
Genus CHIRACANTHIUM, C. L. Koch.
The spiders of this genus are very similar to Clubiona, but the
first leg is longer than the fourth; the falces, especially in
the male, project much farther in front, and the tarsus of the
male palpus is of a form totally different from that found in the
previous genus. Three species are recognised as British, of
which two are found in the Forest, the remaining one C. pennyi,
Cb., being of extreme rarity.
Chiracanthium lapidicolens, Sim. Females have been
found in several localities.
Chiracanthium carnifex, Fabr. A single female at Whip's
Cross.
Genus AGROECA, Westr.
The spiders included in this genus are usually of a pale warm
brown colour, the thorax generally being distinctly marked with
black converging lines. They bear a very strong general
resemblance to some of the representatives of the family
Agelenidae, but may be at once distinguished by their shorter
spinners and by their possessing but two tarsal claws. The
egg-sac formed by these spiders must be a familiar object to
most observant naturalists. It is a goblet-shaped object, closed
at the top, and composed of white silk. Some species, if not all,
have a habit of covering the sac with mud, possibly as a
protection against the attacks of ichneumon flies. I have found
