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. Intescens, Westr., C. neglecta,. 

 Cb., C. holosericea, De Geer., C. snhtilis, L. Koch, C. tvivialis, L. 

 Koch, C. coerulcscem, L. Koch, C. formosa, Tempi, (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. pennyiy 

 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.

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
